<strong>DRAFT</strong> <strong>CONCEPT</strong> <strong>DESIGN</strong> <strong>REPORT</strong><br />

<strong>UNIVERSITY</strong> <strong>OF</strong> <strong>CALGARY</strong><br />

MacKimmie Tower and Block I Repurposing and Renewal<br />

March 31, 2010


Preface<br />

The development of the MacKimmie Library Concept Design<br />

process included a series of design workshops and team<br />

meetings to present progress to date and to discuss<br />

opportunities to explore common design connections. A pivotal<br />

moment during this phase of the work occurred on December<br />

16 th and 17 th at a team design charrette in Toronto. During this<br />

session it was determined that three very strong programmatic<br />

concepts emerged. The first being the “Town Square” concept<br />

which promotes the MLB / MLT Link as a transparent primary<br />

pedestrian and student gathering node within the University<br />

Campus. This town square is strategically located at or near the<br />

heart of campus and serves several key functions including a<br />

new front door to MLB / MLT, a main entrance to the new TFDL,<br />

and is a major intersection and link to the campus pedestrian<br />

network. The second is that the Tower is best suited for<br />

Workplace environments and should be developed as such,<br />

while the Block is best suited for Academic functions and should<br />

be developed as such. The third and central to the project vision<br />

is the strong visual link between Swan Mall the interdisciplinary<br />

and common social space programmed around the perimeter of<br />

the Block and ground floor of the Tower. As a comprehensive<br />

design team we recognize there is much work ahead in resolving<br />

the programmatic space requirements and the exterior synthesis<br />

of the MLT/MLB. We believe that the functional and<br />

programmatic links to the Campus Master Plan Vision are critical<br />

to the success of repurposing of the MacKimmie Library. Our<br />

design team looks forward to the opportunity to explore and<br />

refine solutions around the program and the exterior expression<br />

of the MacKimmie project. In our opinion we have made<br />

significant progress so we ask that you consider where we are<br />

as a snapshot in the early stages of the overall design process.<br />

1.1 PROJECT DESCRIPTION<br />

Stantec Architecture was retain by the University of Calgary in September<br />

2009 to provide condition evaluation, programming and concept design<br />

services which will develop the long term strategy for repurposing the<br />

MacKimmie buildings (MLT / MLB) and establish the basis of the fund<br />

development required to support the Project. This work is Phase 1 of a two<br />

phase process. The second phase will include design and construction of<br />

the project and will be contingent upon receiving funding approval.<br />

The MacKimmie Tower, Block and Link structures will become available<br />

for re-use as a result of the relocation of the majority of the main campus<br />

library functions to the new Taylor Family Digital Library (TFDL) in winter<br />

2011.<br />

The MLB / MLT buildings are located in the heart of the main campus and<br />

combined total some 20,000 gross square meters of available space. They<br />

are joined by the Link, a key circulation component between MLB, MTL and<br />

the TFDL.<br />

It is anticipated that renovation and repurposing of MLT and MLB will form<br />

the key element of the University's master plan to improve space allocation<br />

and utilization across campus. The initial planning phase will determine the<br />

most appropriate utilization of the repurposed buildings and establish the<br />

costs to complete a major refurbishment.<br />

The repurposing of the MacKimmie Tower and Block is integral to the future<br />

master planning of research space across campus. By collecting and<br />

centralizing administrative uses now occupying space in research-capable<br />

buildings, the University will be able to significantly increase research and<br />

research support spaces in key areas, at an advantageous cost. Logical<br />

linking of new MLT/MLB with back-fill opportunities is to be included.<br />

1.2 ROLE <strong>OF</strong> ARCHITECT<br />

Stantec Architecture facilitated and coordinated the design teams’ activities<br />

according to the following parameters:<br />

� Ensure the project mandate is carried out and maintained.<br />

� Collaborate with all stakeholders to achieve the project goals and<br />

objectives.<br />

� Provided input into overall project schedule, timelines and<br />

milestones.<br />

� Ensure an integrated design process is structured around the<br />

following principles:<br />

o Conduct weekly management team meetings to achieve a<br />

comprehensive and holistic resolution to any conflicts and<br />

coordinate the input of team members.<br />

o Conduct regular planning and design meetings and<br />

workshops with the University of Calgary.<br />

o Regular and timely design charrettes to explore options for<br />

the resolution of design issues.<br />

1.3 PURPOSE <strong>OF</strong> THIS <strong>REPORT</strong><br />

The purpose of this report is to provide a concise package of information<br />

illustrating; the analysis of existing conditions, the planning and design<br />

process used, the evaluation of options and finally the recommended<br />

concept design approach to the redevelopment of the MacKimmie Tower,<br />

Block and Link. The report functions as a tool to communicate the<br />

development of the concept design and the steps taken by the design team<br />

to secure funding for phase 2 of the work and to advance the project to<br />

phase 2 of the work which is the development of the design and<br />

construction of the project.<br />

The Concept Design Report illustrates the following:<br />

� Clear direction and defined scope of work pertaining to the repurposing<br />

of the existing MacKimmie Library for future phases.<br />

� Existing condition of building elements and systems<br />

� Opportunities for re-use of existing building elements and systems<br />

� Test / Fit scenarios based on the General Functional Program<br />

� Development of a detailed Functional Program<br />

� Site opportunities and constraints<br />

� Architectural design concepts<br />

� Approach to Sustainable Design<br />

� Structural, Mechanical and Electrical system concepts<br />

MacKimmie Tower and Block I Repurposing and Renewal<br />

1.4 <strong>CONCEPT</strong> <strong>DESIGN</strong> PROCESS<br />

1. INTRODUCTION<br />

The process of developing the Concept Design was broken into four steps.<br />

The first step taken was the inspection of the existing building elements<br />

systems which culminated in a draft Condition Assessment Report<br />

submitted to the UC in November 2009. This report informed the design<br />

process relative to which elements and systems can be repurposed or<br />

rehabilitated and which can not.<br />

The second step taken by the consultant team was to develop options to<br />

test the best fit of the full range of potential uses for the available space. A<br />

variety of teaching spaces, student study spaces and administrative<br />

functions were developed within the tower and block buildings. This<br />

exercise informed the team of the best fit scenarios and the full range of<br />

potential opportunities for development in both buildings.<br />

The third step taken was the development of a detailed functional program.<br />

A series of program surveys and interviews were conducted to better<br />

understand the specific needs and requirements of each department. This<br />

information coupled with the General Functional Program, produced a<br />

detailed document describing which departments can be accommodated in<br />

the exiting MacKimmie buildings. This Detailed Functional Program<br />

informed the Concept Design Process.<br />

The fourth step was the development of a preferred Concept Design option.<br />

Several in-house Design Charrettes were organized for this phase of the<br />

work, with the intent to coordinate common design issues, develop a<br />

common design language, and resolve on-going issues. Several client<br />

workshops were also held to gain consensus on a wide range of issue<br />

including the preferred option for the concept design.<br />

2.1 Existing Campus Plan<br />

Occupying more than 200-hectares in the City’s northwest quadrant, the<br />

University of Calgary plays a significant role within the Province of Alberta<br />

and the City of Calgary. The University contributes to the economic vitality of<br />

the region, educates the future workforce, advances important academic and<br />

research initiatives, and provides public amenities to the surrounding region.<br />

The University of Calgary is located approximately 10-kilometers (6.7 miles)<br />

northwest of downtown Calgary. The campus is strategically situated at the<br />

center of a district defined by academic, research, and medical functions,<br />

and is adjacent to several residential neighborhoods and recreation areas.<br />

The Mackimmie Library (MLT/MLB) is located near the centre of campus<br />

facing Swan Mall to the West and backing on TFDL.<br />

2.3 Site Plan<br />

The existing MacKiimmie Library faces onto Swan Mall and backs onto the new<br />

Taylor Family Digital Library (TFDL). A new +15 link has been recently<br />

constructed connecting TFDL to the MacKimmie Link at the 2 nd floor.<br />

The MacKimmie Tower, Block and Link are connected buildings which will<br />

become available for re-use as a result of the relocation of the majority of the<br />

main campus library functions to the new Taylor Family Digital Library (TFDL) in<br />

winter 2011.<br />

The MLB and MLT are cast-in-place structures which were built in 1963 and<br />

1972 respectively. No major upgrading has occurred to building envelopes,<br />

mechanical systems or electrical systems. The University has undertaken<br />

comprehensive assessments of the existing Tower and Block within the past two<br />

years. It has determined that a wide range of renewals and upgrades are<br />

needed. All electrical and HVAC systems are considered obsolete and the main<br />

building envelope is leaking and in need of a major upgrading and/or<br />

replacement.<br />

The MLB and MLT buildings are located in the heart of the main campus and<br />

combined total some 20,000+ gross square meters of available space. They are<br />

joined by the Link, a key circulation component between MLB, MTL and the<br />

TFDL. This link was constructed with the tower in 1972.<br />

It is anticipated that renovation and repurposing of MLT and MLB will form the<br />

key element of the University’s master plan to improve space allocation and<br />

utilization across campus. The initial planning phase will determine the most<br />

appropriate utilization of the repurposed buildings and establish the costs to<br />

complete a major refurbishment.<br />

The repurposing of the MacKimmie Tower and Block is integral to the<br />

future master planning of research space across campus.<br />

2.4 Climate<br />

Average daily temperatures range from -12 degrees Celsius in the winter<br />

to 23 degrees Celsius in the summer, and discourage outdoor activity<br />

and circulation for much of the year. Design strategies should retain<br />

heat, protect from cold winds, and capture sun during the winter, and<br />

mitigate high temperatures during the summer. The latitude and low<br />

angle of the sun create strong shadows nine months out of the year.<br />

Areas with good solar exposure tend to be more accessible during the<br />

afternoon than in the morning, and include such areas as the Taylor<br />

Family quad and the gathering space south of the Engineering Complex.<br />

Arctic winds blow from the northwest to the southeast and create harsh<br />

conditions across the campus. Large buildings tend to block the wind<br />

and create sheltered areas, while expansive open spaces are sometimes<br />

left exposed. The outdoor areas between Science B and<br />

MacEwan Hall, and between Murray Fraser Hall and the Professional<br />

Faculties Building receive more intense winds, while the corridors<br />

between the Taylor Family quad and the MacKimmie Library Block<br />

experience less intense winds.<br />

These conditions suggest that the most comfortable outdoor spaces on<br />

campus are found on the southern facades of buildings that are<br />

protected from wind and receive ample sunlight.<br />

It was found that the MacKimmie façades located on the eastern<br />

orientation have the greatest potential for contributing to energy savings.<br />

3.1 Campus Master Plan Guiding Principals<br />

The overriding guiding principal for the redevelopment of the MacKimmie<br />

Library is “create dynamic, integrated spaces that adhere to the<br />

principals of the Campus Master Plan as prepared by Sasaki”. The<br />

following elements of the Campus Master Plan Vision statement<br />

informed the design team in its development of key project design<br />

objectives.<br />

� VISION<br />

The University of Calgary master plan establishes a vision for the<br />

campus that builds upon previous planning efforts, is rooted in the<br />

academic and research missions of the institution, integrates innovative<br />

approaches to higher education delivery, and serves as a model of<br />

sustainability. The following fundamental themes and ideas characterize<br />

the campus vision:<br />

o Campus Heart<br />

The master plan creates a well-defined campus heart near the<br />

Taylor Family quad. Landscape and architectural interventions<br />

transform the quad into an active and iconic open space that<br />

reinforces the identity of the University.<br />

o Pedestrian-Oriented Campus<br />

The master plan preserves and enhances the pedestrian qualities<br />

of the campus. It concentrates mission-related purposes around the<br />

academic core of the campus, and situates other uses along its<br />

periphery. The master plan enhances pedestrian paths and bicycle<br />

routes, and improves transit and residential facilities.<br />

o Sustainability<br />

The master plan builds upon the work conducted by the University’s<br />

Office of Sustainability, and supports the environmental, economic,<br />

and social sustainability goals articulated in the draft Sustainability<br />

Master Plan. The master plan addresses sustainability through<br />

working landscapes with integrated storm water management<br />

benefits, transportation demand management strategies that<br />

promote alternate forms of transportation, and building designs that<br />

reduce energy usage, among other strategies.<br />

o Interdisciplinarity<br />

Interdisciplinarity is encouraged through building and land use, and<br />

strategic architecture and open space interventions. The master<br />

plan considers programmatic adjacencies, and provides flexible<br />

venues that encourage collaboration and interdisciplinary<br />

interaction. Interdisciplinary nodes are designed as centers for<br />

academic faculties that foster an open and collegial atmosphere for<br />

faculty and student engagement between departments.<br />

o Enhanced Entrances<br />

The master plan reinforces the unique identities of the four major<br />

campus entrances. University Way is redesigned to function as the<br />

ceremonial and iconic campus entrance for students, faculty, staff,<br />

and visitors. New development and open spaces encourage<br />

pedestrian and transit connections near the LRT University Station,<br />

<strong>CONCEPT</strong> <strong>DESIGN</strong> <strong>REPORT</strong><br />

<strong>UNIVERSITY</strong> <strong>OF</strong> <strong>CALGARY</strong><br />

3. PROJECT OBJECTIVES<br />

while site improvements around the EEEL Building redefines the entrance from 32nd Avenue NW. Street trees and a redesigned plaza position Collegiate Boulevard as<br />

the primary entrance from the West Campus.<br />

o Indoor – Outdoor Engagement<br />

The master plan emphasizes physical and visual connections between indoor and outdoor environments. Facades are articulated with transparent materials, while<br />

circulation is brought to the edges of buildings. Terraces and student life programs are strategically situated along southern facades to capture sunlight, activate<br />

building edges, and negotiate the transition between the indoor and outdoor spaces.<br />

10


Open Space and Connections<br />

Redesigned Taylor Family quad functions as the campus heart.<br />

Primary pedestrian connections to Taylor Family quad and Swann Mall are<br />

reinforced by enhancing access from Campus main entrance.<br />

New open space connection from the University Gateway to the Taylor Family<br />

quadrangle (and Swan Mall) improves connectivity between the quad and other key<br />

campus spaces.<br />

Diagonal pathway carries users into the Taylor Family quad (and Swan Mall) and<br />

maintains a visual connection with the University Gateway.<br />

Swann Mall is maintained as a more passive and informal quadrangle.<br />

Pedestrian Circulation<br />

The goal of the master plan is to create a legible, pedestrian-oriented campus within<br />

an integrated and accessible environment.<br />

The plan prioritizes pedestrian movements and facilitates effective circulation<br />

through compact development, well-defined pathways, and logical connections<br />

between indoor and outdoor environments.<br />

Pedestrian pathways function as part of a larger circulation and open space strategy<br />

that provides pedestrian access to public spaces and key locations on campus and<br />

to surrounding areas. Pedestrian improvements are also designed to facilitate<br />

community access to the campus.<br />

3. PROJECT OBJECTIVES<br />

The master plan also creates a new service access route to the Taylor Family<br />

Digital Library, MacKimmie Library Block and Tower, and the MacEwan Student<br />

Centre by removing the Plus- 15 between Craigie Hall and Murray Fraser Hall.<br />

The plan consolidates service in the MacEwan Student Centre to the east service<br />

bay and removes the west bay by the bookstore. This allows the removal of the<br />

service route through the Taylor Family quadrangle and improves the pedestrian<br />

quality of this critical space at the heart of the campus.<br />

3.2 GENERAL FUNCTIONAL PROGRAM<br />

The University of Calgary provided Stantec with two drafts of the General<br />

Functional Program. The first dated 24 August 2009 and a second dated 30<br />

September 2009. These documents served as the starting point for testing<br />

the best fit for the Tower and Block and provided the baseline for the<br />

program development.<br />

The draft General Functional Program identified several key project<br />

objectives:<br />

� Determine the most appropriate utilization of the repurposed<br />

buildings.<br />

� Centralize administrative uses now consuming space in research<br />

capable buildings.<br />

� Logical linking of new MLT/MLB with backfill opportunities.<br />

� Increase the amount and range of instructional space including<br />

Give priority to small classrooms and to eliminating temporary<br />

instructional spaces.<br />

The draft Campus Master plan also identifies a need for more student<br />

space.<br />

� “..student life is the most significant space deficit on campus”<br />

� “there is a need for additional student life amenities within the<br />

academic precincts.”<br />

� “Concentrate student-centered spaces within campus precincts to<br />

create vitality, and enhance the campus experience for students“.<br />

4.1 Purpose of the Report<br />

The first step in developing the program and concept design for MLT/MLB<br />

was the completion of detailed systems and building investigation. This<br />

work was completed in October 2009.<br />

The purpose of this report was to document comprehensive condition<br />

assessments and building code analysis of the existing University of<br />

Calgary MacKimmie Library Complex comprising of the 14 level Tower, 5<br />

level Block and 3 level Link. This report provided a description of building<br />

elements and systems, their current condition and their suitability for<br />

repurposing as an efficient, code compliant and sustainable academic and<br />

administrative complex.<br />

4.2 Building Code Analysis<br />

The “baseline” for building code requirements is the current 2006 Alberta<br />

Building Code, using Division “B”, Acceptable Solutions.<br />

The extent of non-conformance with the 1960 National Building Code<br />

(NBC) as well as the 1965 and 1970 versions of the National Building Code<br />

is significant considering that fundamentally the codes have not materially<br />

changed in many aspects since the 1965 and 1970 editions of the NBC.<br />

Of particular interest was that the 1970 NBC had included the additional<br />

measures for high buildings similar to current requirements, an aspect that<br />

was not incorporated into the design of the library tower at the time of the<br />

addition of 6 floors, clearly a high building by code definition.<br />

4.3 Geotechnical Assessment<br />

Performance of the renovated library structure, including building<br />

foundations likely will be satisfactory for the duration of a 50 year design life<br />

based on the following:<br />

� The performance of the structures reportedly is satisfactory with no<br />

known problems except for weather-related deterioration of the<br />

exterior cladding;<br />

� The foundations for the MacKimmie Library Tower were initially<br />

designed for a total of 21 floors and only 12 floors have been<br />

constructed;<br />

� The new cladding and change in occupancy will result in<br />

significantly lighter loads;<br />

� Information in the available historical reports for the MacKimmie<br />

Library Tower does not suggest less than satisfactory continued<br />

performance. The attached geotechnical report provides a<br />

preliminary historical summary for the Tower only with general<br />

commentary on current and future uses of the tower. Historical<br />

document review for the Block and Link will be completed once<br />

these documents are made available.<br />

Further investigation must be completed including current code<br />

requirements, inspecting former settlement monitoring hubs and evaluating<br />

the response of the foundations to loading and partial reloading.<br />

4.4 Structural Assessment<br />

All structures were visually reviewed for indications of excessive settlement<br />

or deflection of structural elements. No indications of excessive settlement,<br />

deflection, or other movement of primary structural elements were noted in<br />

any of the three structures. It was observed that the horizontal joints<br />

between precast concrete cladding panels on the McKimmie Library Tower<br />

have reduced over time. However, this is likely due to thermal effects<br />

combined with long term creep and shrinkage of the structure as a whole,<br />

which is expected in reinforced concrete construction.<br />

The primary notes of concern from a structural perspective were indications<br />

of moisture ingress through the building envelope. While the building<br />

envelope is discussed in more detail under the Architectural section of the<br />

report, it is noted here, as preventing moisture ingress will assist in<br />

extending the life expectancy of structural elements.<br />

The structures reviewed in this report appear to be good candidates for repurposing,<br />

as the structural systems remain in generally good condition,<br />

and due to the relatively high original design loading. It should be noted that<br />

construction issues with the Franki compacto piles below the McKimmie<br />

Library Tower limited the pile capacity in the original design, and will likely<br />

not a allow for vertical expansion of the Tower structure in a re-purposing<br />

project.<br />

<strong>UNIVERSITY</strong> <strong>OF</strong> <strong>CALGARY</strong><br />

MacKimmie Tower and Block I Repurposing and Renewal<br />

4. CONITION ASSESSMENT (appendix A)<br />

Fire protection in the MacKimmie Library Complex is currently very limited,<br />

typically consisting of basement sprinklers and standpipes.<br />

All mechanical systems throughout the three buildings are in extremely poor<br />

condition, are inefficient and require replacement. Mechanical issues with<br />

heating and ventilation are endemic and have been band-aided over the<br />

last 20-30 years. The occupancy of the some areas has also changed<br />

drastically since the original design, which has required additional<br />

mechanical system modifications. All mechanical systems are beyond their<br />

life cycle replacement.<br />

The existing mechanical systems should all be upgraded and replaced to<br />

provide long term service for building repurposing. The existing mechanical<br />

systems cannot be relied upon to provide services over the next 40-50<br />

years without a major renovation. It is recommended that a full mechanical<br />

replacement be performed to provide reliability, energy efficient operation,<br />

and to meet current standards for the new proposed occupancies.<br />

4.6 Electrical Assessment<br />

The majority of the electrical systems is original and has passed their<br />

normal life expectancy. Most of the systems are beyond 40 years old and<br />

are showing signs of deterioration. Most of the electrical systems are<br />

obsolete and are very hard to service. The equipment is of old technology<br />

and spare parts are hard to obtain posing concerns for long period of power<br />

outage to the buildings. The size of the existing service rooms does not<br />

meet current code requirements. Clearance in front of the equipment in<br />

many cases poses safety concerns.<br />

The life safety systems are of concern as they do not meet current code<br />

requirements. The emergency generator does not meet current code<br />

requirements and poses great concern that there may be no power in an<br />

emergency.<br />

4.7 Vertical Conveyances<br />

At the time of the inspection the equipment was found to be fair to average<br />

condition. The callback rate on all gearless traction elevators is very high<br />

according to logbook records and from my general knowledge of site.<br />

In most cases the elevators are operating close to design specifications<br />

(with regard to operating times, door times, and leveling accuracy) in spite<br />

of the poor maintenance at the site.<br />

The equipment is completely original with the exception of the minor<br />

upgrade of an infrared multibeam door reversal devices installed on most of<br />

the traction elevators. With proper maintenance at the site, the existing<br />

elevator systems should be able to provide acceptable elevator service to<br />

the building tenants as it exists.<br />

With a full upgrade of the existing elevator system, we are confident that the<br />

library tower elevators can be utilized for office type usage. The average<br />

waiting times have been shown on previous projects to be reduced by 25-<br />

50% from the 1969 technology that is currently in place.<br />

4.8 Architectural Assessment<br />

External building components in the Tower including the exterior pre-cast<br />

concrete cladding, window wall, vapor barrier, and roof are not functioning<br />

as intended, with reported water and air leaks, and difficulties maintaining<br />

internal temperatures. Stained acoustical ceiling tile and discolored and<br />

peeling paint was observed in several areas within the Tower. Some<br />

internal areas are covered with a flexible vapor barrier to prevent damage to<br />

internal components in the event of further leaking.<br />

The interior architectural building components, with the exception of<br />

damage due to water infiltration, are generally outdated but have typically<br />

been well maintained. It is anticipated that all interior partitions and finishes<br />

will be replaced as part of the repurposing of MLT /MLB.<br />

The exterior pre-cast concrete panels have warped and settled, crushing<br />

the control joints and spalling precast corners in numerous locations. The<br />

area immediately adjacent to and around the Tower has been fenced off to<br />

prevent injury to passersby from pieces of falling concrete panels.<br />

It is recommended that all exterior cladding and windows on both MLT and<br />

MLB be removed and replace with a new energy efficient building envelope.<br />

5.1 Workplace Test/Fit – MLT (Tower)<br />

The tower floor plate layout and compact core is well suited for workplace<br />

functions. With relatively minor adjustments to the structural core of the<br />

tower, elevators, mechanical systems, plumbing systems, electrical<br />

systems, and exiting can be made to accommodate an office environment.<br />

In defining new workplace planning opportunities for staff accommodation in<br />

the MacKimmie Block and Tower the Project Team identified guiding<br />

principles to be used in testing the suitability of the floors for staff<br />

accommodation. The most important of these workplace principals included<br />

clarity of circulation, access to natural light, flexibility for future changes and<br />

the integration of new workplace standards being considered by the<br />

University.<br />

The characteristics of the tower proved to be particularly well suited to the<br />

development, with the shallow distance between the core and exterior wall<br />

and with no internal columns, layout options have been developed which<br />

balance the amount of internal enclosed area with the open office areas<br />

adjacent to the windows. The corners of the floor, considered to be prime<br />

‘real estate’ with excellent views are developed as common use meeting<br />

space. A ring corridor surrounding the core allows for multiple tenants on<br />

any floor.<br />

.<br />

5.1 Workplace Test/Fit – MLB (Block)<br />

The MLB, although considered as appropriate for the accommodation of<br />

academic space, is equally suitable for the development of office space<br />

based on these same principals. In developing test fit plans for the block<br />

we have been able to provided access to natural light for all general office<br />

with a deep floor plate through the orientation of space and placement of<br />

services areas in the central area of the floor plate reducing the distance<br />

between the core and exterior wall.<br />

5.2 Academic Space Test /Fit – MLB (Block)<br />

General Approach:<br />

The MLB at 4 stories in height with a steel structural system and<br />

a bay size of 19’-4” x 25’-8” and a floor plate size of<br />

approximately 22,000 SF is particularly well suited for academic<br />

uses which include smaller classrooms (up to approx. 40 seats),<br />

seminar style collaborative learning rooms (approx. 20-24 seats)<br />

and student lounge and study spaces.<br />

Ideally, on a typical floor, the student study spaces and<br />

collaborative learning spaces could be located along the outside<br />

wall to take advantages of natural light and views and the<br />

classrooms could be located to the interior.<br />

The MLB structure is comprised of steel columns and beams,<br />

providing some flexibility in modifying the building superstructure.<br />

For example, removal of interior columns and floor plate is<br />

possible creating large double height space to accomodate 200-<br />

300 seat theatres.<br />

Seminar/Active Learning Rooms<br />

The size and shape of one existing structural bay (i.e. no<br />

columns in the space) is the perfect size for a 20-24 seat<br />

seminar room, orientated in either direction. These rooms could<br />

be bookable 24/7 by students for collaborative group work. They<br />

could be “technologically enhanced” with a wall mounted flat<br />

panel monitor and collaborative software to promote small group<br />

work.<br />

Approximate size of each structural bay: 485 SF<br />

30/40 Seat Classroom<br />

The size and shape of two side by side existing structural bays<br />

(i.e. no columns in the space) is the perfect size for a 30 or 40<br />

seat (standard) classroom. A 40 seat classroom in most<br />

instances is probably too small for a technology enhanced<br />

collaborative learning space. This classroom could be enhanced<br />

with more of the standard type of technology, a ceiling mounted<br />

projector and audio/video capture for distance learning,<br />

conferencing etc. This space can work well within the limited<br />

floor to floor height of 12’-6”.<br />

Approximate size: 970 SF (485 x 2)<br />

80 Seat Classroom (and larger)<br />

Any spaces larger than 40 seats would be a challenge due<br />

primarily to the relatively low 12’-6” floor to floor height and the<br />

structural bay size (columns). The structural bay size of 4 bays<br />

works well (refer to illustration) spatially, but would have a<br />

column in the middle of the space. If these spaces were stacked,<br />

then a new structural system could be introduced for a column free space.<br />

These spaces should be created slightly larger to promote active learning styles such as “large<br />

group/small group” in a collaborative technologically advanced environment. These spaces would<br />

be flat floor with flexible furniture for different layouts dependant on teaching/learning styles.<br />

Approximate size: 1940 SF (485 x 4)<br />

Larger, 150 seat more traditional lecture spaces could be accommodated by restructuring and<br />

stacking the spaces with increased floor to floor heights and raked floors.<br />

5.2 Academic Space Test /Fit – MLT (Tower)<br />

General Approach:<br />

The tower offers a column free space from the core to the<br />

exterior wall which promotes spatial flexibility, at least from a<br />

planning approach. The “post tensioned” concrete structural<br />

system would be difficult to modify in a substantial way, so<br />

effectively limits any major structural modifications to include<br />

large teaching spaces.<br />

The small floor plate of the tower does have a major advantage<br />

for both administrative and academic uses and that is access to<br />

natural light and extraordinary views, effectively creating and<br />

maintaining a very effective connection with the rest of campus.<br />

Smaller academic spaces would fit very nicely around the<br />

exterior leaving the core, elevators, stairs, washrooms and<br />

service rooms and corridor to the interior.<br />

A major limiting factor on these floors related to assembly<br />

occupancies would be occupancy load relative to washroom<br />

requirements and the existing exiting capacities. It should be<br />

noted that the schematic shown would exceeds these capacities.<br />

Another major limiting factor on these floors is the limited space<br />

available in the building core for supply and return air. Larger<br />

occupancies such as classrooms would require mechanical air<br />

systems that would exceed the existing shaft capacities.<br />

Seminar/Active Learning Rooms<br />

The dimension from the core to the exterior wall nicely<br />

accommodates a 20-24 seat seminar room. These rooms could<br />

be bookable 24/7 by students for collaborative group work. They<br />

could be “technologically enhanced” with a wall mounted flat<br />

panel monitor and collaborative software to promote small group<br />

work.<br />

Approximate size: 540 SF<br />

30/40 Seat Classroom<br />

The dimension from the core to the exterior accommodates<br />

30/40 seat classrooms. Due to the column-free space these<br />

classrooms and the seminar rooms can be sized and located in<br />

many different combinations.<br />

A 30/40 seat classroom in most instances is probably too small<br />

for a technology enhanced collaborative learning space. This<br />

classroom could be enhanced with more of the standard type of<br />

technology, a ceiling mounted projector and audio/video capture<br />

for distance learning, conferencing etc. This space can work well<br />

within the limited floor to floor height.<br />

Approximate size: 960 SF (for approx. 40 seats)<br />

6.1 Introduction<br />

Programming is the gathering of information related to an<br />

organization – space requirements, relationships and adjacencies<br />

between departments, building use and the desired resources that<br />

will enable the University of Calgary to develop a highly efficient<br />

workplace which integrates new workplace standards in a<br />

refurbished MacKimmie Library Building. The definition of “space<br />

that works” could include such aspects as:<br />

� Flexibility & Adaptability<br />

� Function vs. Hierarchy<br />

� Emphasis on Team vs Individual Space<br />

� Increased Mobility of Space & People<br />

� Collaborative Tools & Technology<br />

� Transparency “Right to Light”<br />

� Cost effective operations<br />

� End User Control<br />

� Sustainability, Health & Safety<br />

Stantec Architecture approached the programming phase of the<br />

project with great excitement. The Stantec Team focused their<br />

resources on the collection of data required for the design and<br />

implementation of intelligent and strategically conceived workplace<br />

solutions. Working as an integrated team, Stantec and the<br />

University of Calgary Project Team, sought the input of a number<br />

of Key Stakeholders including groups both located within and<br />

outside the existing MacKimmie Tower and Block. Through the use<br />

of a programming questionnaire and subsequent planning<br />

meetings with individuals and groups, by identifying executive<br />

support and recording long term strategies for space use on the<br />

campus, a definition and vision for the project is being developed.<br />

Much of the programming effort focuses on quantitative<br />

calculations using new space standards to meet goals for space<br />

utilization and higher education standards.<br />

Described as the “Functional Program, the documentation<br />

summarizes all shared and support facilities that would be required<br />

if the University of Calgary were to locate particular groups into the<br />

refurbished building. Considered a “living document”, the facility<br />

program is expected to grow and change as the needs of the<br />

University change providing the flexibility to allow for continued<br />

evaluation the work environment requirements to ensure that<br />

facilities development strategy is in line with your long term space<br />

utilization strategy.<br />

6.2 Process<br />

Phase 1 - Define Program Data<br />

1. Define Problem, Scope and Goals<br />

2. Initialize Program<br />

3. Develop Data Base and Collect Data<br />

The University of Calgary has identified the working groups it believes may be<br />

impacted by any work to be undertaken in the refurbishment of the MacKimmie<br />

Library and it is based on this initial work the programming for this project has been<br />

undertaken. Utilizing a well developed methodology for data collection and the use<br />

of computer- based programming tool the Project Team distributed the program<br />

survey and scheduled follow-up interviews. The possible end users of the new<br />

space have been interviewed to identify the probable needs of the project. The<br />

results have been documented and verified through a thorough review process.<br />

Phase 2 - Generate Space Data<br />

1. Confirm Space Standards<br />

2. Generate Detail Listing of Working Groups<br />

3. Tabulate Space Summary<br />

The University of Calgary has recently developed a new space standards strategy<br />

which identifies personnel and group space standards which is the foundation of all<br />

square footage assignments. Using these space standards, the program formulates<br />

the space summary of each working groups and through a series of reviews of the<br />

data, follow by addtional interviews and revisions, a final program has been<br />

developed. Space usage projection is an essential element in studying the future<br />

need of the particular working groups has also been identified.<br />

Phase 3 - Generate Analysis and Findings<br />

1. Building Feasibility Analysis<br />

2. Comparative Data Analysis<br />

3. Adjacency and Space Distribution Analysis<br />

4. Blockings and Stacking<br />

The final phase of program development is the analysis and the synthesis of the<br />

gathered information in order to gain a clear understanding of the client's growth<br />

pattern and flexibility requirements, the programmer studies, compares and breaks<br />

down the data. The study included proximity between major working groups and<br />

growth projections between major groups and that of the total company. The<br />

purpose of the studies is to identify the growth patterns, review the degree of<br />

flexibility required for the project and to identify any discrepancies on the data<br />

received. The studies are useful in making informed decision regarding planning<br />

direction and on how best to allocate the spaces efficiently within the new spaces.<br />

The resulting program document includes a summary that illustrates the horizontal<br />

and vertical distributions of space using distribution tables and the blocking and<br />

layering diagrams<br />

7.2 Site Concept Plan<br />

The proposed site plan responds to several key Campus Master Plan<br />

Objectives.<br />

The first objective is to reinforce and enhance TFDL Quad as the campus<br />

heart. The proposed plan does this with the addition of a major pedestrian<br />

node between MLT and MLB. This “town square” is a key pedestrian node<br />

providing a new major pedestrian access to both TFDL and TFDL Quad.<br />

The second objective is to provide flexible venues that encourage<br />

collaboration and interdisciplinary interaction and to design Interdisciplinary<br />

nodes as centers for academic faculties that foster an open and collegial<br />

atmosphere for faculty and student engagement between departments.<br />

The proposed plan provides major venues and opportunities in the “town<br />

square”, in the Block and ground floor of the Tower for student events,<br />

formal/informal study and socialization.<br />

7.3 Town Square<br />

� Indoor / Outdoor Space<br />

The master plan emphasizes physical and visual connections between<br />

indoor and outdoor environments. Facades are articulated with transparent<br />

materials, while circulation is brought to the edges of buildings. Terraces<br />

and student life programs are strategically situated along southern facades<br />

to capture sunlight, activate building edges, and negotiate the transition<br />

between the indoor and outdoor spaces. The “town square” has to potential<br />

to provide this visual connection by utilizing transparent facades and by<br />

bringing the outdoors inside.<br />

7.5 Administration Tower<br />

� Visual Landmark<br />

The MacKimmie Tower is located in the historic centre of the Campus. It is<br />

highly visible from distant neighborhoods surrounding the Campus and is<br />

the most dominant structure as one enters the Campus at University Gate.<br />

The location and visual prominence of the tower could be exploited as a<br />

key landmark structure or beacon signaling the “Heart of the Campus”. The<br />

tower has two significant features which could be developed to highlight<br />

the tower.<br />

The first is Level 6A which is a storey and a half high which could be<br />

developed as special event space and treated differently from the rest of<br />

the tower. An example of how this could be achieved is the Administrative<br />

Tower at the De Young Museum in San Francisco.<br />

The second key feature is the penthouse, which could be developed as an<br />

illuminated cap which covers the entire footprint of the tower. This would<br />

provide a highly visible landmark particularly at night.<br />

7.6 Roof<br />

� Green Roof<br />

The block roof is highly visible from the MacKimmie Tower, TFDL, Social<br />

Science Tower and the Education Tower. This large prominent roof area<br />

could be exploited for its visibility, for its accessibility, its potential as a roof<br />

top garden using drought resistant native grasses and flowers, as an<br />

active/passive recreation and study space, as a pollutant filter, for<br />

scrubbing the surrounding air, for controlling storm water runoff and for<br />

sound absorption.<br />

The image to the right shows potential for developing not only a “healthy<br />

roof” but also how it can reflect the surrounding landscape. In the case of<br />

the MLB roof, the connection to and relationship with Swan Mall is obvious.<br />

The image below shows how the building elevation facing Swan Mall could<br />

be treated as a living wall.<br />

7.7 Building Envelope<br />

� Tower<br />

The tower will feature carefully selected glazing extending from<br />

approximately three feet above the floor to the underside of the ceiling in<br />

order to maximize daylight penetration, but reduce solar heat gains and<br />

heat losses. All glazing will be high performance double glazing, with a<br />

balance between a low shading coefficient to minimize cooling loads, and a<br />

high visible light transmittance to facilitate daylighting. With the exception<br />

of the ground floor which will have 100% glazing, all orientations will have<br />

35% window to wall ration (WWR) from a 3' sill height to underside of<br />

ceiling.<br />

A double façade has been explored for the tower; extending from the 7 th to<br />

the top floor on the southern orientation(s), this feature reduces solar heat<br />

gains in the summer while retaining envelope heat losses and acting as a<br />

“greenhouse” to passively heat the building and preheat incoming building<br />

air in the winter. Trombe Wall (double facade) on "South" and "East"<br />

facade starts on level 7 and extends to top floor. The trombe wall is 100%<br />

glass, single glazed with interior double glass consistent with lower and<br />

North facing facades.<br />

� Link<br />

The “Link” will be 100% glazed with a polycarbonate roof to permit<br />

daylighting and to create a visible and signature access point for the<br />

MacKimmie building and the adjacent TFDL. The polycarbonate roof will<br />

provide superior insulating qualities compared to a conventional glass roof,<br />

while still allowing the introduction of diffuse light into the commons space<br />

below. This system has a further benefit in that it reduces glare and radiant<br />

heating effects.<br />

� Block<br />

The block will feature a combination of floor to ceiling punched windows<br />

overlooking Swan Mall and smaller windows on the “West” and “South”<br />

facades.<br />

North façade will feature 80% WWR except for north class "block" which is<br />

0% glazing. Glass is floor to ceiling.<br />

West façade will feature 30% WWR, 3' sill height to underside of ceiling<br />

"South" 30% WWR, 3' sill height to underside of ceiling<br />

7.8 Sustainability<br />

Sustainable Design Objectives<br />

The integrated design team’s primary sustainable design objective for the<br />

MacKimmie Library Repurposing Project was to create a project that focuses on a<br />

superior indoor environment, while reducing resource consumption during<br />

construction and operation. Specific design objectives that will be achieved with the<br />

current concept design include:<br />

� Application of an integrated design process, including involvement of<br />

all primary design disciplines and University stakeholders.<br />

� Eligibility for LEED-Canada NC Gold Certification<br />

� A reduction in energy performance of 45% compared to ASHRAE 90.1<br />

2007<br />

� Facility compatibility and alignment with Campus sustainability<br />

initiatives including integration with the new district energy and<br />

cogeneration plant and campus stormwater management plan.<br />

Sustainable Design Features<br />

The project has aligned its sustainable design features with the LEED-Canada NC<br />

version 1.0 rating system, as a stated design objective is to attain LEED Silver or<br />

higher certification. As such, sustainable design strategies shall be listed according<br />

to the performance categories within LEED, namely site, water, energy, materials,<br />

indoor environment, and innovation.<br />

Site:<br />

As an existing building, the MacKimmie building is located in the heart of the<br />

University of Calgary campus. As such, the project is conducive to a number of<br />

sustainable strategies such as being located in a non-ecologically sensitive area,<br />

being in close proximity to multiple modes of alternative transportation including a<br />

comprehensive pedestrian network and mass transit such as the city LRT and major<br />

bus routes. By redeveloping an existing building, site disturbances are minimized<br />

and existing campus infrastructure such as the University storm water management<br />

system can be incorporated to treat and reduce stormwater run off. To further aid in<br />

the reduction of heat island effect, promote natural habitat in the campus, and to<br />

reduce stormwater run-off, a green roof is being proposed for over 50% of the<br />

building, with a white-roof proposed for the remainder. The green roof will be located<br />

on the “Block” portion of the building, where it will be visible not only from the<br />

MacKimmie “Tower” but also the adjacent Taylor Family Digital Library and other<br />

adjacent buildings.<br />

Water:<br />

The project plans to take advantage of left over process water from the district<br />

cooling system to offset potable water use for toilet flushing and green roof irrigation<br />

and/or establishment. Low flow water fixtures for lavatories, toilets, urinals, and<br />

showers will further help conserve water and reduce sanitary sewer loads, and the<br />

green roof will utilize native and adaptive plant species to further reduce reliance on<br />

landscape irrigation systems.<br />

Energy:<br />

The facility will feature a number of energy efficient features. A double façade has<br />

been explored for the tower; extending from the 7 th to the top floor on the southern<br />

orientation(s), this feature reduces solar heat gains in the summer while retaining<br />

envelope heat losses and acting as a “greenhouse” to passively heat the building<br />

and preheat incoming building air in the winter.<br />

The building envelope will feature high performance, well insulated walls, roofs, and<br />

exposed floors. Thermal bridging will be minimized. Target envelope performance<br />

values are as follows:<br />

� Walls: Effective R17<br />

� Roof: Effective R30<br />

� Glazing: Overall U-value 0.35; Shading Coefficient: 0.50 for Block and<br />

Tower, Link SC = 0.70<br />

The façade has been developed to balance access to daylight and views with<br />

reduced HVAC loads and energy consumption. The ground floor, facing north, will<br />

be nearly 100% glazed with floor to ceiling vision glass to permit views onto the<br />

adjacent Swan Mall while accomplishing a level of transparency between the<br />

building, its occupants, and the outdoors. The “Link” will be 100% glazed with a<br />

polycarbonate roof to permit daylighting and to create a visible and signature access<br />

point for the MacKimmie building and the adjacent TFDL. The polycarbonate roof<br />

will provide superior insulating qualities compared to a conventional glass roof, while<br />

still allowing the introduction of diffuse light into the commons space below. This<br />

system has a further benefit in that it reduces glare and radiant heating effects. The<br />

block will feature a combination of floor to ceiling punched windows overlooking<br />

Swan Mall and smaller windows on the “West” and “South” facades. The tower will<br />

feature carefully selected glazing extending from approximately three feet above the<br />

floor to the underside of the ceiling in order to maximize daylight penetration, but<br />

reduce solar heat gains and heat losses. All glazing will be high performance double<br />

glazing, with a balance between a low shading coefficient to minimize cooling loads,<br />

and a high visible light transmittance to facilitate daylighting. The façade glazing is<br />

summarized as follows:<br />

Block:<br />

� "North" = 80% WWR except for north class "block" which is 0% glazing.<br />

Glass is floor to ceiling.<br />

� "West" 30% WWR, 3' sill height to underside of ceiling<br />

� "South" 30% WWR, 3' sill height to underside of ceiling<br />

� Ground floor north = 100% WWR (except at north class "block"), floor to<br />

ceiling.<br />

Tower:<br />

� Trombe Wall (double facade) on "South" and "East" facade starting on<br />

level 7 and extending to top floor. The trombe wall is 100% glass, single<br />

glazed. Interior glass is as per other elevations (35% WWR)<br />

� All orientations: 35% WWR 3' sill height to underside of ceiling. Double<br />

glazing behind trombe wall.<br />

� North ground level = 100% glazing floor to ceiling.<br />

Link:<br />

� North and South = 100% Glazing floor to ceiling.<br />

� Roof: 100% "skylight" using kalwall/polycarbonate panels.<br />

The total overall window to wall ratio based on these inputs is 41%.<br />

The building lighting system will feature high efficiency lighting products and a<br />

sophisticated control system. The facility will utilize an addressable lighting control<br />

system such as the “Encelium” Energy Control System, which will be also<br />

connected to the building automation system. The lighting control system will<br />

include motion sensors, photocells, daylight sensors and override switches. This<br />

system will be provided for the zone switching of lighting during normal hours, after<br />

hours and daylight sensing. This will provide total flexible lighting control and also<br />

aid in reducing energy consumption. The addressable lighting control system will<br />

allow the ability of measurement of energy and usage of the lighting. The primary<br />

lighting control in the offices, classrooms and labs will be occupancy sensors with<br />

dimming via daylight sensors. Low voltage switching will also be provided in these<br />

areas as an override feature. Occupancy sensors utilized in storage rooms and<br />

wash rooms for switching the lights.<br />

The building HVAC system will be fed from the campus district energy system. The<br />

Tower plans to utilize a chilled beam system which reduces the amount of fan power<br />

used to condition the building. The Block will feature a displacement ventilation<br />

system for the lecture theatres and classrooms, and an overhead variable air<br />

volume distribution system for the remaining portion of the building. The Link will be<br />

heated via an in-slab radiant heating system, and during the winter will be ventilated<br />

by the Block ventilation system. During the summer, the Link will be passively<br />

cooled and naturally ventilated. All portions of the building will feature<br />

supplementary hydronic perimeter heating, heat recovery ventilation, and CO2<br />

demand controlled ventilation.<br />

Design Validation Energy simulations were undertaken to evaluate the potential<br />

energy savings for the proposed design, comparing the results to both the existing<br />

building energy consumption and the LEED reference energy code. Results are in<br />

Appendix D. The results indicate the proposed design is eligible for up to a 45%<br />

reduction in energy costs compared to ASHRAE 90.1-2007; as such, five (5) Energy<br />

and Atmosphere Credit 1 (Optimized Energy Performance) points have been carried<br />

in the project’s preliminary LEED scorecard.<br />

The facility will be fully commissioned and will feature a Measurement and<br />

Verification (M&V) system to ensure ongoing operational performance and energy<br />

cost accountability and savings.<br />

Materials:<br />

The building will focus on retaining as many structural elements as feasible so as to<br />

reduce demand for resources. Recycled and regional materials will be specified to<br />

both preserve the environment and to promote the local manufacturing economy,<br />

while wood products will be sought that attain Forest Stewardship Council<br />

certification. The new building elements will be constructed in a durable manner to<br />

reduce long term maintenance and repair costs.<br />

Indoor Environmental Quality:<br />

7. PLANNING AND <strong>DESIGN</strong> <strong>CONCEPT</strong>S<br />

The building will feature systems that are conducive to high air change<br />

effectiveness, such as displacement ventilation systems which have demonstrated<br />

superior thermal comfort while reducing disease transmission and associated<br />

impacts on student academic achievement and staff absenteeism. Further, the air<br />

system will be designed with a high level of air filtration (MERV 13 filters) and will<br />

contain CO2 monitoring and outdoor air control devices to ensure good indoor air<br />

33


quality. Automatic sensors will control lighting based on occupancy, daylighting,<br />

and occupant control and override.<br />

Access to daylight will be promoted via glazing that extends to the underside of<br />

ceilings, and a balance between the quantity of glazing for daylighting and the<br />

associated energy penalties for too much glass. Research and energy codes have<br />

demonstrated that daylighting can be achieved while minimizing energy<br />

consumption at a 35 to 50 percent window to wall ratio, and this project will attain<br />

approximately a 41% ratio. Views to the outdoors will be promoted via a program<br />

that promotes open spaces around the perimeter, with enclosed offices and<br />

classrooms in the core of the building. Views for such core spaces will be attained<br />

via the use of glass partitions.<br />

Innovation:<br />

As a higher education project, the facility will strive to be a showcase for<br />

sustainability and education. A digital learning kiosk and energy “dashboard” may<br />

be installed in the Link to educate occupants on the sustainable features being<br />

incorporated and to monitor real time consumption of energy and water resources.<br />

The green roof may feature a variety of plant species and roof technologies to<br />

demonstrate to various student groups the various systems on the market. One<br />

concept for the green roof includes using a “tile” system where the plants are made<br />

up of various tiles, which can allow for replacement or reorganization of the green<br />

roof, potentially to create various patterns, logos, or messages using different<br />

coloured plants and a grid pattern. If the double façade is included, the design team<br />

proposes incorporating a high level of monitoring sensors and equipment to<br />

conduct research on the benefits of such a feature in Calgary’s local climate.<br />

Preliminary LEED Scorecard<br />

Enclosed is a current LEED-Canada NC scorecard for the concept design. There<br />

are a number of credits that can be attained based on the above descriptions, with<br />

several other credits, primarily related to constructability, that will be ascertained<br />

during the design and construction process. Based on the systems described and<br />

typical construction practices, the scorecard demonstrates LEED Gold is attainable.<br />

7.9 Mechanical Systems<br />

� Introduction<br />

The HVAC system design concepts for the mechanical systems were strongly<br />

influenced by the existing building construction, design constraints, and proposed<br />

occupancies. In particular the existing Library Tower had several constraints that<br />

required an innovative mechanical concept to meet the comfort and sustainability<br />

objectives of this renovation.<br />

The Library Tower is constructed with a pre-stressed concrete slab with no columns<br />

between the core and the perimeter wall. Therefore, the core dimensions are fixed<br />

and cannot be changed without major revisions to slab connections. The existing<br />

allowances for mechanical shafts are limited since the original design utilized very<br />

high velocity supply ductwork for the main risers. The mechanical systems also had<br />

to provide energy efficient operation, which would be very difficult to achieve with<br />

the high velocity, high pressure ductwork design. The existing floors also have<br />

ceiling space challenges with low ceiling heights and flush mounted lighting fixtures.<br />

Reuse of the existing central systems provide limited energy efficiency opportunities<br />

other than upgrading to a variable air volume system.<br />

Upgrading the Library Tower to current standards required expansion of the existing<br />

washrooms to accommodate handicapped washroom stalls, new communication<br />

rooms, and new larger electrical rooms. This created pressure on the core area<br />

space allocations, since providing these rooms outboard of the core was not<br />

desirable due to vertical shaft requirements. Two redundant elevator shafts<br />

provided some of this additional space, but this was inadequate to fulfill all of the<br />

needs. It was also determined that the sixth floor mechanical floor space would be<br />

valuable real estate with high ceilings. Therefore, a distributed cooling system was<br />

determined to be the best solution for this building, which minimizes vertical shaft<br />

space requirements. It is desirable to increase the floor to ceiling height, most likely<br />

by exposing the concrete structure above. The exposed ceiling provides an<br />

opportunity to take advantage of the thermal mass of the concrete floor structure.<br />

The Library Block is a completely different construction than the Tower, with a<br />

mechanical penthouse spanning the entire building. This building was more flexible<br />

to renovations with steel deck construction and non-stressed slabs. However, the<br />

steel structure with required spray-on fire proofing is not an attractive finish for<br />

exposing the structure. This building was more conducive to classroom spaces<br />

from a mechanical perspective, as the ventilation can be provided from underfloor.<br />

The Link building currently has limited mechanical with a single multi-zone unit<br />

supplying cooling, heating and ventilation. The construction of a new Link structure<br />

provides several mechanical opportunities to provide an energy efficient structure.<br />

New floor slabs can be used for radiant heating and cooling to provide conditioning<br />

only where required, and a mixed-mode system with a natural ventilation mode can<br />

be incorporated<br />

� Displacement Air<br />

Displacement ventilation is the use of low velocity air typically at 18°C-19°C to<br />

provide cooling and ventilation of the space. Low velocity air is either delivered<br />

through floor diffusers in concert with a raised floor system, or by low wall mounted<br />

horizontal diffusers. Displacement ventilation provides excellent air change<br />

effectiveness by sweeping contaminants from the occupied space to the higher level<br />

return space. Displacement ventilation provides an additional benefit by allowing<br />

additional hours of free-cooling operation, particularly in Calgary’s climate.<br />

However, displacement ventilation has limited capacity to handle high cooling loads,<br />

so the envelope must be high performance or potentially a double façade.<br />

The Library Tower building construction does not lend itself to the use of<br />

displacement ventilation. The use of a raised floor displacement system creates<br />

many difficulties with required ramps or stair reconstruction. The additional cost of<br />

the raised floor system is also significant. The use of wall mounted displacement<br />

ventilation diffusers is possible but will require fixed overhead ductwork and fixed<br />

wall locations. The major disadvantage of displacement ventilation is the<br />

requirement for compartmental units located on each floor, which will require at least<br />

10 sq.m. of valuable floor space.<br />

The exception in the Tower is the potential 6 th floor converted space which is<br />

proposed to contain meeting type spaces. This floor has very high ceilings and<br />

would be a great candidate for displacement ventilation. The provision of<br />

compartmental units on this floor is also less disruptive with a meeting room layout.<br />

7. PLANNING AND <strong>DESIGN</strong> <strong>CONCEPT</strong>S<br />

The Library Block building provides a good application for displacement ventilation<br />

in the proposed large lecture theatres and classrooms. Displacement air is provided<br />

at low level under the seats and is very effective at providing a comfortable<br />

environment for these spaces.<br />

The new Link is also a good application for displacement ventilation due to the lower<br />

level occupancy and very high ceiling space. Displacement air can be delivered at<br />

low levels, possibly in some of the new main stair risers. This will ensure<br />

conditioning of the occupied areas and will allow some of the large empty space<br />

above to be partially conditioned. Displacement air can also be well utilized in<br />

conjunction with mixed mode natural ventilation. Exterior openings can provide the<br />

equivalent of displacement ventilation performance by allowing cool outside air to<br />

distribute along the floor.<br />

35


� Active Chilled beams<br />

Active Chilled beams are a newer technology borrowing on an old concept of<br />

induction. Active Chilled beams utilize a primary air source, typically from a<br />

dedicated outdoor air system, to provide induced air into the space. The chilled<br />

beam incorporates a higher temperature chilled water coil located within the chilled<br />

beam. The primary air is blown through air jet nozzles that induce room air through<br />

the chilled water coil. This provides three times the primary airflow to increase<br />

effective room ventilation effectiveness and room air change rates. Chilled beams<br />

typically incorporate a dew point sensor and separately controlled chilled water loop<br />

to ensure that water does not condense on the coil surface. The design of chilled<br />

beams and the air jet nozzles also ensures the acoustic performance meets the<br />

space requirements, so chilled beams are comparable or better than standard<br />

ceiling diffusers. Chilled beams require a primary air connection and chilled water<br />

lines, but do not require a condensate drain. Chilled beams are quite energy<br />

efficient since the have low fan power requirement, utilize higher temperature chilled<br />

water, and require a lower air volume primary air handling unit.<br />

The Library Tower is a great candidate for a chilled beam system due to the core<br />

area restraints and the floor space limitations. The existing ceiling can be exposed<br />

and the chilled beams mounted on the underside of the concrete at the same<br />

elevation as the lighting. The primary air ducts will be much smaller than equivalent<br />

variable air volume ductwork, which will allow the chilled beams to be mounted<br />

higher than the existing ceiling. Attention to detail on the layout of primary air<br />

ductwork and chilled water lines can provide a neat and non-obtrusive installation.<br />

The chilled beam system will not require a compartmental unit, so valuable floor<br />

space is saved.<br />

The Library Block could also potentially use chilled beams for the non-classroom<br />

student spaces and the lower floor registrar area. However, the occupancy for<br />

these areas is less controlled and may have significant student gatherings at times.<br />

This could create significant short term latent loads from people, which could lead to<br />

condensation issues on the chilled beams. Therefore, this option would be limited<br />

to office type areas located in the registrar.<br />

The Link building would not be a good candidate since the chilled beams would<br />

have to be mounted too high to be effective.<br />

� Raised Floor<br />

A raised floor system consists of tiled flooring system installed above the existing<br />

concrete slab. These tiles can be concrete or wood and are typically installed on a<br />

pedestal system to provide an interstitial space under the floor for cooling and<br />

ventilation air. This interstitial space can range from low electrical only floors that<br />

are 100 – 125 mm high to combination floors that range from 200 mm to 450 mm or<br />

more. It is recommended that an interstitial floor space for cooling and wiring be a<br />

minimum of 300 mm to provide room for proper crossovers, distribution ductwork,<br />

and equipment.<br />

Raised floor systems utilize either a displacement ventilation diffusers or turbulent<br />

flow diffusers to provide cooling and ventilation. Displacement ventilation systems<br />

have been described previously, but a raised floor system allows displacement<br />

diffusers to be easily located throughout the floor area. A turbulent flow diffuser<br />

system utilizes a similar principle as displacement ventilation but provides a mixed<br />

zone in the occupied area. The mixed zone area is up to approximately 1.5-1.8 m,<br />

with a non-mixed zone above that is at a higher temperature than the occupied<br />

zone. The majority of contaminants and high level heat loads are contained in the<br />

upper zone and do not enter the space. The turbulent flow system can handle<br />

higher cooling loads in the space.<br />

The challenge with the Library Tower building is the requirement for access ramps<br />

to the new raised floor height, or adjustment of existing stairways and elevator<br />

openings to the new floor height. The ramp solution will be very difficult in the tight<br />

floor space available on each floor, is awkward with the stair configuration, and is<br />

generally a poor solution. The adjustment of the existing stairwells and elevator<br />

openings will require rebuild of the entire stairway, new elevator openings, and a<br />

new elevator penthouse. This is a substantial expense over and above the<br />

significant cost of the raised floor system itself. However, a raised floor system will<br />

also allow exposure of the existing concrete structure, and will result in a higher floor<br />

to ceiling height. The major disadvantage of a raised floor system is the<br />

requirement for compartmental units located on each floor, which will require at least<br />

10 sq.m. of valuable floor space.<br />

The use of a raised floor system in the Library Block and Link was not practical with<br />

the existing building construction, the intended space usage, and the difficulty with<br />

implementation. Therefore, a raised floor system is not recommended.<br />

8.2 Sustainability ( Reference Appendix D )<br />

� OVERVIEW<br />

The project is pursuing LEED ® NC-Canada certification; as such, the building is<br />

required to meet Energy and Atmosphere (EA) Prerequisite 2: Minimum Energy<br />

Performance and are striving to achieve points for EA Credit 1 Optimize Energy<br />

Performance. The selected compliance path for both objectives is ASHRAE 90.1-<br />

2007 and the associated Energy Cost Budget methodology.<br />

For this purpose an energy model was developed in order to assess the buildings<br />

predicted energy consumption per the Building Energy Cost Budget Method in<br />

chapter 11 of the reference standard.<br />

A double façade was explored for the tower; extending from the 7 th to the top floor.<br />

This feature reduces solar heat gains in the summer while retaining envelope heat<br />

losses and acting as a “greenhouse” to passively heat the building and preheat<br />

incoming building air in the winter. Three models were developed to explore this<br />

option fully; a model with the double façade located on the southern orientation, one<br />

with the double façade located on the eastern orientation, and one model with no<br />

double façade. It was found that the double façade located on the eastern<br />

orientation contributed the greatest energy savings and therefore all results<br />

described in the following sections refer to this model.<br />

The model demonstrates that as currently designed, the MacKimmie Complex<br />

achieves the ASHRAE 90.1 minimum requirements per the Energy Cost Budget<br />

Method, and further demonstrates a 45% decrease in regulated annual modelled<br />

energy costs. The current version of LEED asks for the building to demonstrate a<br />

reduction in energy cost compared to the energy cost of the ASHRAE 90.1-1999<br />

standard. While it is recognised that ASHRAE 90.1-2007 is more stringent than the<br />

1999 standard, by using the 2007 standard it better aligns with the University<br />

guidelines and gives a more conservative points estimate. The proposed design<br />

meets EA Pr. 2 and is eligible for up to seven (7) EA Credit 1 points.<br />

The simulations and the design are preliminary in nature; the accuracy of the<br />

simulations reflects this and are typically considered to be within ±10% of the final<br />

design. Therefore, at least two projected LEED Energy and Atmosphere Credit 1<br />

energy points as reported in this document should be deducted from each building’s<br />

initial LEED scorecard and deemed a “maybe” until such time as a final compliance<br />

simulation is completed. Two EA Credit 1 points should be deemed as “maybes” for<br />

Mackimmie and five (5) points should be deemed achievable.<br />

� ENERGY MODEL<br />

Energy analysis and simulation can be used to estimate the energy consumption of<br />

a building based on the local climate characteristics, system choices, and geometry.<br />

The purpose of this energy simulation was to confirm the building will meet the<br />

energy requirements of the LEED Canada-NC rating system.<br />

Simulation tools bring architectural and engineering design aspects together to<br />

predict how different building components will interact with each other and the<br />

environment. By understanding the relationship between individual building<br />

components and the building as a whole, the model can estimate the energy use of<br />

the proposed building.<br />

� ENERGY ANALYSIS GOALS<br />

Baseline/Proposed Building<br />

An energy model was developed to represent the current buildings’ proposed<br />

design. Using this energy model, each building was characterised by:<br />

Electricity Consumption and Demand<br />

Natural Gas Consumption<br />

Total Energy Cost<br />

Process related equipment is not covered under the applicable reference standard<br />

or LEED and was therefore excluded from the simulation. However, approximations<br />

for plug loads were made to ensure Heating Ventilation and Air Conditioning<br />

(HVAC) system loads were accurately simulated.<br />

ASHRAE (Code) Building<br />

The proposed building was analysed for ASHRAE compliance by following the<br />

Building Energy Cost Budget Method. This involved creating a separate energy<br />

model with the same building layout, and by altering the performance parameters of<br />

glazing, envelope, mechanical and electrical (lighting) systems to the minimum<br />

values permitted by the code. The annual predictive energy cost estimate of this<br />

simulation was compared to the results of the baseline building design simulation to<br />

ascertain whether the annual regulated energy cost of the proposed building was<br />

45% less than the code reference, thereby meeting the minimum energy<br />

requirements of LEED Canada-NC version 1.0.<br />

Conclusions<br />

The models demonstrated that as currently designed the MacKimmie Building<br />

achieves the ASHRAE 90.1 minimum requirements per the Energy Cost Budget<br />

Method, and further demonstrate a 45% decrease in regulated annual modelled<br />

energy costs; therefore the proposed design meets LEED Energy and Atmosphere<br />

(EA) Prerequisite 2 and is eligible for up to seven (7) EA Credit 1 points.<br />

It should be noted that the simulations and the design are preliminary in nature; the<br />

accuracy of the simulations is typically considered to be within ±10% of the final<br />

design and therefore at least two (2) LEED EA Credit 1 energy point as reported in<br />

this document should be deducted from each building’s initial LEED scorecard and<br />

deemed a “maybe” until such time as a final compliance simulation is completed.<br />

Two EA Credit 1 points should be deemed as “maybes” for Mackimmie and five (5)<br />

points should be deemed achievable.<br />

8.3 Mechanical<br />

� OVERVIEW<br />

This system description outlines the mechanical systems proposed for the<br />

expansion of the existing University of Calgary MacKimmie Library. Its intent is to<br />

define the scope and nature of the heating, ventilation, cooling, plumbing, fire<br />

protection and building automation systems to be provided.<br />

The mechanical systems for all three buildings require complete replacement as<br />

noted in the Condition Assessment Report. Therefore, complete replacement of<br />

plumbing and heating systems provided the opportunity to update these systems to<br />

efficient designs. All mechanical systems will be updated to provide reliable and<br />

energy efficient service for the next 50 years.<br />

Codes and Standards<br />

The mechanical systems will be designed and installed to comply with the latest<br />

editions of the following codes as applicable.<br />

Alberta Building Code 1997<br />

Canadian Plumbing Code 1997<br />

N.F.P.A. Codes<br />

W.C.B. Regulations<br />

Canadian Gas Code CGBA149.1 M89<br />

CSA Standards<br />

Canadian Fire Code<br />

Local Building By-Laws<br />

In addition to the above, the mechanical systems will be designed to comply with the<br />

applicable standards issued by:<br />

ASHRAE (American Society of Heating, Refrigeration and Air Conditioning<br />

Engineers Inc.)<br />

ASPE (American Society of Plumbing Engineers)<br />

SMACNA (Sheet Metal and Air Conditioning Contractors National<br />

Association)<br />

The building is also being designed to meet both:<br />

The new building energy performance will be a minimum of 21% better<br />

than an equivalent building designed to meet the Canadian Model National<br />

Energy Code for Buildings. The building energy performance will also<br />

achieve a minimum performance of 8% better than ASHRAE 90.1-2007.<br />

The goal will be to achieve energy performance much greater than the<br />

minimums, which will be verified by the Energy Modelling process.<br />

The Canadian Green Building Council’s Leadership in Energy and<br />

Environmental Design (LEED) Gold standard. It is anticipated the LEED<br />

Canada NC Version 2.0 will be released prior to design of these<br />

renovations, which will provide revised point matrices, new point<br />

definitions, and additional opportunities.<br />

Design Criteria<br />

Indoor Design Conditions<br />

Winter: 21ºC, 30% minimum humidification<br />

Summer: 23ºC, maximum 60% humidity, typical 40-45%.<br />

Outdoor Design Conditions<br />

Winter: -33ºC (1%)<br />

Summer: 29ºC db, 17ºC wb (2½%)<br />

Ventilation Rates<br />

Ventilation rates shall be in accordance with ASHRAE 62, Current Edition.<br />

Controls<br />

All building controls will be upgraded to a full DDC control system, based on the<br />

based building control contractor Siemens. All pneumatic controls will be deleted<br />

and replaced by new electronic controls that will provide substantially improved<br />

controllability for the system. Energy metering as per U of C standards will be<br />

provided for chilled water and heating water systems. It is intended that LEED<br />

IPMPV credit requirements will be pursued to provide energy monitoring and<br />

confirmation of energy performance.<br />

� TOWER<br />

Site Services<br />

The building is served by a 200mm (8”) dia. sanitary sewer service and a 300mm<br />

(12”) dia. storm sewer service connected to manholes on the mains to the East.<br />

The building sanitary and storm sewer services are cast iron piping with hub and<br />

spigot joints. A 150 mm (6”) dia. domestic water service and chilled water is<br />

provided through the campus tunnel piping system network. These services are<br />

adequate to support the renovated building.<br />

Plumbing<br />

The plumbing piping systems will be completely replaced including domestic water<br />

lines, sanitary lines, and storm water lines.<br />

Plumbing fixtures will be water conserving, good commercial grade. Water closets<br />

will be low flow, dual-flow flushometer type. Urinals will be 0.1 gallon per flush<br />

models that provide a slight cleaning affect to the urinal surfaces. Faucets will be<br />

low flow and will be infra-red activated. Sanitary and storm drainage will be<br />

provided throughout in accordance with the Plumbing Code.<br />

Domestic hot water will be generated from the hot water system by the use of two<br />

domestic hot water heat exchangers. Domestic hot and cold water will be supplied<br />

to all fixtures with the exception of the toilets. River process water will be used for<br />

toilet flushing.<br />

Heating<br />

Heating systems will be completely replaced and will generally consist of radiant<br />

panels since high temperature heating water is readily available from the Co-<br />

Generation Plant. Standard entrance heaters will be provided at all entrances. The<br />

backside of the radiant panels will be used as a light shelf element where<br />

appropriate.<br />

Two new redundant primary high temperature hot water to low temperature hot<br />

water heat exchangers will be provided in the vault. A new high temperature hot<br />

water to steam generator will also be provided to serve humidification needs of the<br />

building.<br />

Ventilation and Cooling<br />

The recommended solution for cooling and ventilation of the Tower building is an<br />

Active Chilled beam system. A dedicated outdoor air unit complete with a heat<br />

wheel will provide ventilation, dehumidification, filtration and primary air supply for<br />

the chilled beams. This unit will supply sufficient primary air to drive the chilled<br />

beams, which will typically exceed the ASHRAE 62 minimum values. LEED<br />

recognizes that exceeding ASHRAE minimum values by 30% can increase the<br />

overall ventilation effectiveness. Providing a larger ventilation unit will also provide<br />

the University flexibility for program or space use changes.<br />

Active chilled beams will be located throughout all typical office floors and will be<br />

supplied from a tempered chilled water loop. The chilled beams will be mounted on<br />

the underside of the concrete structure as tight to the underside as possible,<br />

generally at the lighting elevation. Primary ductwork and chilled water lines will<br />

extend radially from ring mains located in the central exit corridor to provide a neat<br />

installation.<br />

The 6 th floor area will be provided with displacement ventilation compartmental<br />

units. Displacement ventilation diffusers will be located in the meeting room walls to<br />

provide cooling and ventilation. High overhead returns will return high level heated<br />

air back to the compartmental units.<br />

The new envelope should either be a high performance envelope or a double<br />

façade. The ideal envelope would be a double façade with motorized exterior<br />

50


window shades located in the interstitial space. This solution allows the window<br />

shades to be protected from the wind and prevents the majority of direct solar gain<br />

from entering the occupied space. The MacKimmie Tower allows the provision of a<br />

double façade system without requiring separate framing, which may make the<br />

system economical. The double façade will be ventilated by low level operable<br />

dampers and a relief fan at the top. Pre-heated outdoor air will be directed to the<br />

makeup air system in the winter.<br />

The intent of the new envelope would be to provide operable windows to allow<br />

occupants the access to fresh air. It is also intended that some of these openings<br />

be motorized to allow a night purge cycle to take advantage of the concrete thermal<br />

mass. Calgary’s climate is ideal for use with a high mass building to save operating<br />

energy. Night-time temperatures are from 10 to 15 degrees C cooler than daytime<br />

highs. Cool air at night will be used to flush the building and store cool within the<br />

high mass slab, ready for the next day’s operations. The daytime thermal<br />

flywheeling of the mass within the structure will be recharged by using the operable<br />

windows to drag cool air through the facility at night. The system will be automated<br />

to prevent overcooling of the facility or simultaneous heating and cooling.<br />

Chilled water will be provided from the central chilled water plant with cooling coils<br />

and chilled beams sized for high temperature differentials. The University of<br />

Calgary standard control valve and metering detail will be used for this connection.<br />

Fire Protection<br />

A new fire pump will be located in the basement of the MacKimmie Tower building<br />

to serve the entire facility. All three buildings will be considered as one building for<br />

the purposes of fire protection. The Siamese connection will be relocated to the<br />

front NE of the Tower building adjacent to the front entrance.<br />

Sprinklers will be provided throughout the building as per NFPA 13. New fire<br />

extinguishers located in lockable cabinets will also be provided throughout as per<br />

NFPA 10.<br />

� BLOCK<br />

Site Services<br />

The building is served by a 150mm (6”) dia. sanitary sewer service and a 300mm<br />

(12”) dia. storm sewer service connected to manholes on the East side of the<br />

building. A 150 mm (6”) dia. domestic water service and chilled water is provided<br />

through the campus tunnel piping system network. These services are adequate for<br />

the new expansion and may be reused.<br />

Plumbing<br />

The plumbing piping systems will be completely replaced including domestic water<br />

lines, sanitary lines, and storm water lines.<br />

Plumbing fixtures will be water conserving, good commercial grade. Water closets<br />

will be low flow, dual-flow flushometer type. Urinals will be 0.1 gallon per flush<br />

models that provide a slight cleaning affect to the urinal surfaces. Faucets will be<br />

low flow and will be infra-red activated. Sanitary and storm drainage will be<br />

provided throughout in accordance with the Plumbing Code.<br />

Domestic hot water will be generated from the hot water system by the use of two<br />

domestic hot water heat exchangers. Domestic hot and cold water will be supplied<br />

to all fixtures with the exception of the toilets. River process water will be used for<br />

toilet flushing and irrigation of the green roof areas.<br />

Heating<br />

Heating systems will be completely replaced and will generally consist of radiant<br />

panels since high temperature heating water is readily available from the Co-<br />

Generation Plant. Standard entrance heaters will be provided at all entrances.<br />

The old steam generators will be deleted and two new redundant primary high<br />

temperature hot water to low temperature hot water heat exchangers will be<br />

provided in the vault. A new high temperature hot water to steam generator will also<br />

be provided to serve humidification needs of the building.<br />

Ventilation and Cooling<br />

Ventilation and Cooling<br />

Two displacement ventilation units will be provided to serve the lecture theatres and<br />

classroom spaces. These units will be 100% outside air and will incorporate a heat<br />

recovery wheel. Displacement air will be distributed through stair risers in raked<br />

classroom areas and through low level wall diffusers in flat classrooms.<br />

Two conventional variable air volume units will provide ventilation and cooling to the<br />

student and registrar areas. These units will provide for occupancy loads in these<br />

areas that may have significant variability. Typically these areas will not have high<br />

outside air percentages, so a standard mixed air unit will provide good performance.<br />

Chilled water will be provided from the central chilled water plant with cooling coils<br />

sized for high temperature differentials. The University of Calgary standard control<br />

valve and metering detail will be used for this connection.<br />

� LINK<br />

8. <strong>CONCEPT</strong> <strong>DESIGN</strong><br />

Site Services<br />

Site services for the Link will be connected to the Block area where required. It is<br />

not anticipated that site services will be required for this area.<br />

Plumbing<br />

Plumbing will not be required within the Link area. Storm lines may be required<br />

depending on the final roof configuration, these will be directed towards the Block<br />

building and connected to storm.<br />

Heating<br />

The Link area will utilize radiant heating in the new slabs, since this area will be<br />

reconstructed as part of the proposed renovations. Standard entrance heaters will<br />

be provided at all entrances. Heating water for the Link will be provided from the<br />

Block mechanical room.<br />

Ventilation and Cooling<br />

The Link area will be served by radiant cooling in the slab (based on a switchover<br />

system) and a displacement ventilation system located in the occupied zones. The<br />

design intent is to use “unused” ventilation air from the Block building to provide part<br />

of the outdoor air supply to the Link Area. A damper arrangement and carbon<br />

dioxide monitor will allow the unit to reuse this ventilation air or draw directly from<br />

outside based on energy efficiency.<br />

The building is being designed to utilize a hybrid natural ventilation system. When<br />

the outdoor air temperature is conducive to ventilating, operable louvers or windows<br />

will allow cool outside area into the Link. The displacement ventilation system will<br />

be augmented by the use of these openings to introduce ventilation and cooling air<br />

into the facility.<br />

In order to assure that openings draw air into the Link regardless of wind direction or<br />

location, openable louvers and fans will be designed for the Link area. The negative<br />

pressure developed within the Link will promote a positive airflow from the openings,<br />

through the Link, and out the relief openings.<br />

It is also intended that some of these openings be motorized to allow a night purge<br />

cycle to take advantage of the concrete thermal mass. Calgary’s climate is ideal for<br />

use with a high mass building to save operating energy. Night-time temperatures<br />

are from 10 to 15 degrees C cooler than daytime highs. Cool air at night will be<br />

used to flush the building and store cool within the high mass slab, ready for the<br />

next day’s operations. The daytime thermal flywheeling of the mass within the<br />

structure will be recharged by using the operable windows to drag cool air through<br />

the facility at night. The system will be automated to prevent overcooling of the<br />

facility or simultaneous heating and cooling.<br />

8.4 Electrical<br />

� Overview<br />

The design goals are to provide electrical systems that provide flexibility,<br />

adaptability and accessibility so that the building can accommodate a mix of activity<br />

types within each floor area for both the present and future needs. The electrical<br />

systems presented will be designed so as to facilitate cable replacement, renewal<br />

and removal as the needs and activities of the users and departments change over<br />

the life of the building.<br />

The selection of the electrical systems are also based on the following goals:<br />

Project capital budget.<br />

Design creativity, excellence and innovation.<br />

Energy efficiency to achieve low operating and maintenance costs while<br />

supporting the facility function.<br />

Reliability and continuity of electrical systems.<br />

Capacity for future modifications and extensions.<br />

The electrical systems design will comply with the following applicable codes and<br />

standards:<br />

All laws, ordinances, rules, regulations, codes and orders of all authorities<br />

having jurisdiction relating to this work.<br />

The Canadian Electrical Code, CSA Standard C22.1 and the applicable<br />

building codes.<br />

All equipment will be CSA approved and ULC certified.<br />

� Primary Electrical Service<br />

The existing U of C primary electrical distribution is at 13.2 kV and is fed from two<br />

Enmax Substations. Each existing building is fed in a ring main loop configuration<br />

with 350mm teck cable with a maximum loading of 50 percent (%) so that either side<br />

of the loop feed can be loaded to carry twice the load in the event there is a fault on<br />

either side of the loop. These ring main loops are run in the existing tunnel system.<br />

The existing services to the Tower and Block are old and past their expected life.<br />

There are also serious safety issue concerns with them. The existing services will<br />

be removed and replaced with new services in new larger electrical rooms.<br />

Tower<br />

New switchgear will be provided for the Tower which will include a new four switch<br />

13.2kV switchgear and will be located in a new main electrical room that will be<br />

located in the basement. Two new dry type 13.2kV-347/600V, 2000kva transformers<br />

will be provided and will be set up as a double ended switchboard configuration with<br />

a normally open tie breaker. The 600-volt switchboards will be rated for 3000 Amps<br />

for the Tower<br />

Block and Link<br />

New switchgear will be provided for the Block and Link which will include a new four<br />

switch 13.2kV switchgear and will be located in a new main electrical room that will<br />

be located in the basement. Two new dry type 13.2kV-347/600V, 1500kva<br />

transformers will be provided and will be set up as a double ended switchboard<br />

configuration with a normally open tie breaker. This will provide redundancy in the<br />

power service. The 600-volt switchboards will be rated for 2000Amps for the Block<br />

and Link<br />

General<br />

Both of these new switchgear will be incorporated into the existing ring mains in the<br />

tunnel.<br />

These switchboards and will be complete with drawout breakers for maintenance<br />

and operational ease. The 600-volt switchboards will be divided into two sectors,<br />

connected by a tie circuit breaker for each of the new services. Each side of the<br />

switchboard will be fed by one of the two step down transformers. This will provide<br />

reliable power in the event one transformer/feeder was to fail. Secondary feeders<br />

will be taken from the unit substation switchboard to the distribution panels located<br />

throughout the building.<br />

Digital Power metering equipment will be provided on each side of the 600-volt<br />

switchboard and will be tied to the campus monitoring system for maintenance<br />

troubleshooting and energy management activities.<br />

� Power Distribution<br />

All the power will be distributed throughout the building from the 600-volt, 3 phase,<br />

and 4 wire switchboards located in the basement electrical rooms in both the Tower<br />

and the Block.<br />

Tower<br />

In the Tower, from the main 600V switchboard, there will be three 347/600V bus<br />

duct risers. One will be for floor 1 to 6. The second will be for floors 7 to 12. The<br />

third one will be for the mechanical equipment. Each floor will have a 347/600V<br />

distribution board which will be fed from the bus duct with plug-in type fused<br />

switches. . These 347/600V distribution boards will then feed 347/600V panelboards<br />

for lighting and 600-120/208V transformers for all the 120V and 208V power<br />

requirements. 120/208V distribution boards will be from the 600-120/208V<br />

transformers in each floor electrical riser rooms which in turn will feed all the<br />

panelboards to serve all the 120V and 208V loads for the theatres and classrooms<br />

plus all general housekeeping receptacles, incandescent lighting fixtures and 120V<br />

and other 208V equipment. A 800 Amp, 600-volt feed (wire and conduit) will be run<br />

form the 600-volt mechanical busduct to a 800 Amp, 600-volt distribution panel in<br />

the mechanical penthouse to feed all the mechanical equipment and the elevators.<br />

Block and Link<br />

In the Block, from the main 600V switchboard, conduit and wire will be run to a<br />

distribution board which will then feed each floor electrical riser room 347/600V<br />

distribution boards. These 347/600V distribution boards will then feed 347/600V<br />

panelboards for lighting and 600-120/208V transformers for all the 120V and 208V<br />

power requirements.120/208V distribution boards will be from the 600-120/208V<br />

transformers in each floor electrical riser rooms which in turn will feed all the<br />

panelboards to serve all the 120V and 208V loads for the theatres and classrooms<br />

plus all general housekeeping receptacles, incandescent lighting fixtures and 120V<br />

and other 208V equipment. A 400 Amp, 600-volt feed (wire and conduit) will be run<br />

form the 600-volt switchboard in the basement electrical room to a 400 Amp, 600volt<br />

distribution panel in the mechanical penthouse to feed all the mechanical<br />

equipment and the elevators.<br />

General<br />

To reduce the arc-flash energy level, a breaker will be installed on the secondary<br />

side of all distribution transformers.<br />

To aid in the reduction of harmonics on the distribution system, all the 225 kVa, 600-<br />

120/208 volt transformers will be phase shifting harmonic mitigation zigzag<br />

transformers. All the plug-in bus ducts on all the floors will have double neutrals.<br />

This will eliminate harmonics at the transformer on each floor thus preventing any<br />

harmonics being introduced on the feeder risers and into the existing campus<br />

distribution. Further, all mechanical equipment fed from variable frequency drives<br />

<strong>CONCEPT</strong> <strong>DESIGN</strong> <strong>REPORT</strong><br />

<strong>UNIVERSITY</strong> <strong>OF</strong> <strong>CALGARY</strong><br />

MacKimmie Tower and Block I Repurposing and Renewal<br />

will incorporate in line reactors to eliminate any harmonics caused by the variable<br />

frequency drives.<br />

� Emergency Power<br />

A diesel fired standby emergency generator set rated at 500 kVa, 347/600-volt, 3<br />

phase, 4 wire will provide emergency power to life safety equipment such as fire<br />

alarms, emergency lighting fire pumps, communication and security equipment.<br />

Also, it will be used to provide emergency power to standby loads such as building<br />

basic heating systems (freeze protection) and one elevator.<br />

Automatic transfer switches will provide transfer of loads to the generator in case of<br />

power failure. There will be two transfer switches. One will be for life safety<br />

equipment and the other for non-life safety equipment.<br />

The emergency generator will be located outside in a exterior sound attenuated<br />

enclosure and a skid mounted fuel tank.<br />

� Lighting<br />

The lighting levels will be designed in accordance with the recommendations of the<br />

Illuminating Engineers Society (IES). The following lighting levels and lighting power<br />

densities will be used as design guidelines:<br />

The above design lighting power densities a minimally 25% below the requirements<br />

as stipulated in ASHRAE 90.1.<br />

Lighting fixtures will be selected based on visual comfort, energy efficiency and<br />

color rendering.<br />

The primary goal of the lighting design is to provide an overall energy efficient<br />

system which will comprise of efficient fixtures, lamps and controls.<br />

The majority of the lighting will be energy efficient fluorescent utilizing T5 lamps and<br />

electronic ballasts. This is a cost-effective solution in terms of initial capital cost as<br />

well as operating costs and provides higher color-rendering lamps at no cost<br />

premium. All fluorescent ballasts will be instant start, high quality and high power<br />

factor.<br />

The typical light fixtures in offices, labs and classroom spaces will be linear<br />

direct/indirect suspended fluorescent fixture.<br />

Architectural decorative luminaires will be provided in the public open areas.<br />

53


Two lamp strip lights with wire guards, T5 lamps and electronic ballasts will be used<br />

in all service rooms, janitor rooms, and storage rooms.<br />

The lecture theatres will be lit with a combination of recessed fluorescent fixtures,<br />

compact fluorescent pot lights. The lecture theatre's lights will be controlled by a<br />

dimming system lighting control system which will allow preset light switching for<br />

different modes of light levels.<br />

Where practical, LED fixtures will be utilized for both interior and exterior lighting.<br />

Incandescent lamp sources will be minimized and used only where absolutely<br />

necessary.<br />

The primary lighting control in the offices, classrooms and labs will be occupancy<br />

sensors with dimming via daylight sensors. Low voltage switches will also be<br />

provided in these areas as an override feature.<br />

Occupancy sensors utilized in storage rooms and wash rooms for switching the<br />

lights.<br />

LED illuminated exit lights at all building exits and as required to provide exit<br />

guidance in accordance with the Alberta Building Code.<br />

Partial interior lights will available while the building is on emergency power.<br />

The facility will utilize a addressable lighting control system such as the “Encelium”<br />

Energy Control System, which will be also connected to the building automation<br />

system. The lighting control system will include motion sensors, photocells, daylight<br />

sensors and override switches. This system will be provided for the zone switching<br />

of lighting during normal hours, after hours and daylight sensing. This will provide<br />

total flexible lighting control and also aid in reducing energy consumption. The<br />

addressable lighting control system will allow the ability of measurement of energy<br />

and usage of the lighting.<br />

� Grounding & Lightning Protection<br />

The grounding system will consist of a ground grid made up of 4-20 mm x 3000 mm<br />

copper ground rods connected together with 1-#3/0 bare copper ground wire. From<br />

this grid a #3/0 ground wire will be run to a ground bus located in each of the<br />

basement electrical rooms<br />

The grounding resistance for the electrical power system will have a maximum<br />

resistance to ground of 5 ohms. A wall mounted 6 mm by 50 mm and 1 m long<br />

minimum copper ground bus will be provided in each electrical room and in the main<br />

electrical service rooms. The ground bus will be located in the back of the room. The<br />

ground bus will be interconnected with the ground electrode and ground bus in the<br />

switchboard as well as the lighting conductors and water pipes.<br />

A separate communication ground bus will be provided for the communication and<br />

this ground bus will be connected with this main building grounding bus.<br />

A central grounding system will be provided for all switchboards. All grounded<br />

busses from switchboards, transformers, and panelboards will be connected at a<br />

central ground bus in the main electrical room.<br />

A separate green ground wire will be provided for all circuits.<br />

All transformers, switchgear, motor control centres, and panelboards will be<br />

grounded back to the basement electrical room ground bus.<br />

Lightning protection will provided for the building. The system will consist of air<br />

terminals mounted on the perimeter of the top of the building and ground conductors<br />

from the air terminals to ground rods to provide a path for lightning current to travel<br />

safely to the ground.<br />

� Voice and Data Systems<br />

There will be a main communication room for each of the Tower and the Block.<br />

These will be located in the basement of the respective buildings and will serve as<br />

the primary location for all data/voice entrance cables coming from the tunnel<br />

system, backbone distribution and server locations. The rooms will meet all codes<br />

and standards outlined by both the University of Calgary and the EIA/TIA 568-A.<br />

Cables entering from the tunnel supplying both voice and data links will consist of a<br />

200-Pr. Sealpic/Aircore ATMM voice cable originating from the Administration<br />

Building, and two 72 Single Mode cables coming from the Math Science Building<br />

and ICT Building respectively.<br />

All backbone cable will originate from the main communications rooms located in<br />

the basement. For all data applications, 24 Single Mode Optic Cable will be run to<br />

the Communication Riser rooms located on each floor and patched into an ADC<br />

Fibre Optic Patch Panel. For voice applications, 50-Pr ATMM Category 6A cable<br />

will also be run to each Communications Riser room and punched down in either a<br />

BIX or 110-Style frame. We feel that these cables will provide the flexibility needed<br />

for this building coupled with the support for all present and future applications that<br />

may arise in the years to come.<br />

Each of the Tower and the Block will have Communication Riser rooms will be<br />

located per floor and vertically aligned. Each riser room will have 3 x 4” sleeves<br />

located between riser rooms. Extending from this area will be a vertical ladder tray<br />

that will connect to a horizontal cable tray for distribution within the riser room.<br />

Data and telephone cabling will be proposed Performance Category 6A. Each cable<br />

will consist of (4) unshielded twisted pairs (UTP).<br />

Together with EIA/TIA 606 and the University of Calgary standards, voice and data<br />

jacks will be clearly identified using labels. In addition to this, there will also be a<br />

AutoCAD drawing of each floor located in each communication riser room for<br />

identification purposes and a clear understanding of the voice/data layout.<br />

Offices and work spaces will be provided with (2) tele/data outlets located on<br />

opposite walls to allow flexibility of equipment location.<br />

Classrooms and theatres be provided with tele/data outlets as required.<br />

Wireless access points will be provided throughout the building for complete<br />

wireless access in the entire building.<br />

Cooling will be provided for the equipment heat loads in the all the communication<br />

rooms. Dedicated emergency power receptacles and a signal ground will also be<br />

provided in each of these rooms.<br />

8.5 Structural<br />

� Overview<br />

The McKimmie Library Tower, Block and Link represent three distinct structures due<br />

to differences in their original design and construction. The Tower structure is<br />

largely able to accommodate a multitude of uses and occupancies while meeting<br />

current building codes, but is limited in flexibility with respect to modifications of the<br />

existing structure. The Block is similarly able to accommodate a multitude of uses<br />

and occupancies to meet current building codes, but is somewhat flexible in<br />

accommodating revisions to the existing structure. This may include removal of<br />

some columns and floor slabs to created two storey spaces, and relocation of stairs<br />

and elevators. Finally, the Link is a much smaller structure that has negligible<br />

additional capacity to accommodate revisions to use and occupancy, revisions to<br />

the structure, or to meet current building codes.<br />

� Tower<br />

The McKimmie Library Tower consists of primarily cast-in-place concrete<br />

construction. Concrete floor slabs span over concrete beams and joists, which in<br />

turn span from perimeter concrete columns to the interior concrete core. This interior<br />

core contains the elevator shafts, concrete stairs and mechanical shafts. This<br />

central core also provides the lateral load (wind and seismic) resistance of the<br />

structure. The perimeter columns protrude beyond the edge of the floor slabs, and<br />

taper from larger columns at the base to smaller columns at the top of the building.<br />

The concrete construction and the limited number of vertical load carrying elements<br />

in the Tower limit the potential for significant structural modification. However, this is<br />

largely compensated as the lack of columns does leave an open floor plate that<br />

allows flexibility for architectural and interior design.<br />

The Tower’s original design loading for a typical floor slab was 7.2 kPa (kilopascals),<br />

which is equal to150 psf (pounds per square foot). This is a relatively high loading<br />

that was due to the use as a library, and the high floor loading that results from<br />

stacking of books. For comparison, a typical design loading for an assembly use is<br />

4.8 kPa, and for administration and office areas a typical design loading is 2.4 kPa.<br />

Additionally, it has been proposed that the existing pre-cast concrete exterior panels<br />

be replaced with a lighter curtain-wall system. This combination of factors serves to<br />

decrease the expected vertical loading on the existing core, columns and foundation<br />

piles for a re-purposed Tower when compared to the original design.<br />

This reduced loading is important when investigating the lateral stability of the<br />

Tower under seismic conditions. The lateral stability of the Tower is provided by the<br />

concrete walls that form the central core. Seismic design requirements as specified<br />

by National and Provincial design codes have increased significantly in recent<br />

editions, and are currently much more stringent that was the case during the original<br />

design of the Tower. Increased lateral loading on the Tower structure translates to<br />

increased loading on vertical structural elements (columns and core walls). Of<br />

particular concern are the foundation piles. The foundations are the lowest loadbearing<br />

elements in a structure, and as such vertical loading is compounded to its<br />

highest degree. Additionally, foundation piles are very difficult to access should any<br />

reinforcing work be necessary. A preliminary lateral stability analysis of the Tower<br />

indicates that the increased vertical loads due to seismic loading applied per current<br />

building codes is offset by the reduction in gravity loading due to revised use and<br />

occupancy and a lighter building envelope. The only seismic upgrading of the Tower<br />

structure currently identified would be strengthening the lowest level of the core<br />

walls, from the basement level to the underside of the main level. This could be<br />

accomplished by either application of external steel bracing, or placing of an<br />

additional thickness of concrete adjacent to the existing wall.<br />

There is potential that the decrease in vertical loading on the Tower structure as<br />

described below may actually cause the structure to rebound from the soil. This<br />

would be realized as an upward vertical movement of the structure as load is<br />

released from the soil at the foundations, and the soil elastically returns toward its<br />

pre-loading location. The actual extent of this rebound would require further<br />

investigation at the detailed design phase. However, it is not expected that the<br />

overall rebound value would be a significant cause for concern. Of more concern<br />

would be the potential for differential rebound. This may be caused by a non-uniform<br />

reduction of the loading. This could then cause adjacent structural members to<br />

move differentially and cause local structural damage. The best way to<br />

accommodate this would be to conduct a carefully sequenced demolition of heavy<br />

elements, particularly the existing pre-cast building envelope. The demolition would<br />

be sequenced such that the reduction in load occurs uniformly across each<br />

foundation pile.<br />

The Tower has a structural steel framed mechanical penthouse on the roof level.<br />

This penthouse could relatively easily be modified or re-constructed to<br />

accommodate new mechanical equipment installed with the re-purposing of the<br />

Tower.<br />

� Block<br />

The McKimmie Block structure consists of structural steel beam, joist and column<br />

framing with concrete floor slabs. The current lateral load resisting system of the<br />

Block consists of rigid frames formed by the beams and columns. The structural<br />

steel construction will allow for simpler and more cost effective removal and<br />

replacement of structural members.<br />

The proposed re-purposing of the Block includes some significant structural<br />

revisions, including removal of existing stair and elevator shafts and removal of<br />

some columns to allow for larger classroom areas.<br />

As discussed above with regards to the Tower, the Block will also be subject to<br />

higher lateral loads due to seismic events as specified by current codes when<br />

compared to the original structural design. This will likely require an upgrade to the<br />

lateral load resisting system. It is proposed that this be accomplished by installation<br />

of structural steel cross-bracing. This cross-bracing would consist of relatively slim<br />

steel members, which would have some flexibility in its layout and location. The<br />

bracing may be placed at the Block’s perimeter, forming part of a new building<br />

envelope, or placed within interior walls. The interior walls at the large lecture<br />

theatres and the mechanical shafts are likely locations.<br />

This upgrade of the existing lateral load resisting system would allow for the removal<br />

and relocation of elevator and stair shafts, as their lateral stability properties could<br />

be made redundant. The existing shafts could be infilled with a typical floor slab<br />

structure to become useable space.<br />

8. <strong>CONCEPT</strong> <strong>DESIGN</strong><br />

Generally, columns can not be removed from exisiting buildings as the resultant<br />

span between remaining columns will increase, often to double the initial span. This<br />

requires an increased floor beam depth and strength. Additionally, this applies a<br />

higher load on the remaining columns and foundations. The removal of columns for<br />

the large classrooms in the Block is made possible by two primary factors. The first<br />

is the reduction of the design live load on the floor slabs due to use and occupancy.<br />

Similar to the Tower as discussed previously, the Block was originally designed for a<br />

relatively high live loading of 8.1 kPa. It is expected that this may be reduced to 4.8<br />

kPa for academic and student areas. The second factor is that the large classrooms<br />

will essentially be two stories in height. This would result in the removal of large<br />

portions of the existing second and third floors. Therefore, the longer spans resulting<br />

from the removal of some columns are generally offset by the combined reduction in<br />

live load and floor area. However, removal of the columns will require replacement<br />

of the floor beams, both to accommodate the increased span and the slope of the<br />

classroom theatre. From preliminary analysis, this is expected to be either a steel<br />

beam or truss, approximately one metre in depth. Refer to Figures<br />

55


8.5 Structural (cont.)<br />

The removal of columns without increasing the load on other adjacent columns and<br />

piles would allow for structural revisions to the existing superstructure, without the<br />

need for work to the existing pile foundations. This will allow the lower levels, and<br />

large areas of the upper levels to remain untouched, reducing the demolition and<br />

new construction scopes.<br />

The proposed new classrooms extending beyond the east face of the Block are a<br />

significant increase the existing protruding structure. This area would require<br />

significant new construction, including new pile foundations. However, this work<br />

would be more easily achieved in this location as it is at the perimeter of the existing<br />

building, allowing for excavation and drilling without significantly impacting the main<br />

Block structure.<br />

Similar to the Tower, the structural steel mechanical penthouse could be relatively<br />

easily re-constructed to suit new mechanical requirements.<br />

� Link<br />

The proposed re-purposing of the McKimmie Library structures includes a<br />

significantly revised link. The existing two storey, structural steel framed link is<br />

designed for a 4.8 kPa live load due to use and occupancy on level 2, and for snow<br />

loading on the roof level. The ground level is a concrete slab-on-grade. This<br />

configuration does not allow for additional capacity in existing members and<br />

foundations to be realized by reduction of live loads as was accomplished in the<br />

Tower and Block structures. Significant additional capacity would be required to<br />

achieve the proposed vertical expansion of the link to match the height of the Block.<br />

Therefore, it is likely that the existing link will be removed and reconstructed in its<br />

entirety, including construction of new pile foundations. Due to the desired<br />

transparency of the new link, it can be expected that the new construction will<br />

consist of structural steel, which generally allows for a much lower and slimmer<br />

profile than concrete. New construction of the link could easily accommodate<br />

seismic design requirements of current building codes.<br />

As discussed in the Block above, it is proposed to relocate the elevator currently in<br />

the interior of the Block to the Link, at the perimeter of the Block. Elevators generally<br />

require specialized foundations. As foundation work is very difficult within an existing<br />

building, it was deemed that relocation of the elevator to the link area would allow<br />

for the necessary foundation to be constructed.<br />

Recommended and Required Upgrades<br />

RECOMMENDED UPGRADES (LOW PRIORITY) - SHORT TERM (24+ months)<br />

a) Car cab renovations - The elevator cabs of all units appear to be original and<br />

are in poor to below average condition. Car cab interior renovations will be required<br />

within the next 2 to 4 years.<br />

Total cost: $200,000<br />

Required Upgrades – long term (5-10 years)<br />

NONE<br />

Recommended Upgrades (high priority) – short term (1-2 years)<br />

b) Code compliance - voluntary upgrades - The existing elevators meet the<br />

applicable code under which they were installed; there are no outstanding<br />

mandatory retroactive code upgrades required at this time. There are, however,<br />

several features that the existing elevators do not have that are required on new<br />

elevators and installation of these devices is optional:<br />

(1)Hall door retainers and fire gibs;<br />

(2)Car door restrictors.<br />

It is recommended that these devices be installed on all elevators where necessary<br />

to ensure that the highest possible degree of safety is maintained at the site.<br />

Estimated cost $60,000 (plus taxes)<br />

Recommended Upgrades - (1-2 years)<br />

Control and fixture upgrade - Traction Elevators<br />

The existing control systems for all of the traction elevators is the original openlooped<br />

VVDC-MG relay logic based system that can be maintainable for the<br />

foreseeable future. This type of relay logic system is very maintenance intensive.<br />

Leveling accuracy of elevators with this type of control system can only be<br />

guaranteed to within +/- 3/4" under normal operating circumstances. The existing<br />

systems will provide inconsistent leveling as the system ages, regardless of normal<br />

maintenance routines, and problems will likely worsen as the expertise available in<br />

the industry to adjust this type of system becomes more and more difficult to source.<br />

The current dispatching system also utilizes mechanical relays and contact or coil<br />

failures are very difficult to troubleshoot.<br />

Plans should be made to upgrade the traction elevator control system to newer<br />

microprocessor based, closed-loop control systems. This would include replacement<br />

of controllers, new VVVF motor drives and AC motors, refurbishing of machines,<br />

installation of auxiliary braking devices, installation of compensating devices and<br />

load weighers, and replacement of hall and car fixtures with vandal proof barrier free<br />

compliant devices.<br />

The benefits of such a modernization would include: guaranteed floor leveling<br />

accuracy to within 1/4", smooth, step-less acceleration and deceleration, reduction<br />

in unscheduled shutdowns and malfunctions, reduction in waiting times for hall calls<br />

by 25 to 50 percent.<br />

Estimated cost $1,400,000 (plus tax) for all traction units<br />

Tower<br />

The budget should be in the range of 450K per unit for a major upgrade, including<br />

all machine room controllers, refurbishment of gearless machines (or replacement<br />

with newer AC machines), new fixtures and cab interiors, new door operators, and<br />

all new wiring per UofC spec. Pricing would include new 3-phase disconnects and<br />

fire alarm panel tie-in’s. These would be regenerative drives also with potentially a<br />

good amount of power savings and reduced cooling requirement in machine room.<br />

To change the elevations of entrances (mechanical raised flooring option), the<br />

budget would have to be increased 100K per elevator with a minimum to a<br />

maximum of 200K if the machine room floor would need to be raised also.<br />

Would have to add approx 3-4 weeks per car for this work add on (total 15-19 week<br />

per elevator). Pricing would include all new doors and hall entrances and door locks.<br />

Block<br />

There is a need to have a minimum of 2 elevators, with one being a minimum of<br />

2500-3500 lb’s for stretcher capability. May want both elevators close to each other<br />

So if one is being serviced (or just out of service) the other can fill in.<br />

Suggestion would be 1-2500 pound passenger traction elevator and 1 - 4000-5000<br />

pound service traction elevator.<br />

Budget would be (not incl structure costs).<br />

2500 lb – 350K - time to install 12-14 weeks<br />

4000 lb – 400K - time – 13-15 weeks<br />

5000 lb – 425K - time – 14-16 weeks<br />
