CETSC

Initiative

Description

Utilize industry leading architect and engineering firms

specializing in energy and sustainable infrastructure

services to improve facility operating efficiencies.

Established 5-year BPA contracts with 10 GSA

contractors for10 energy related services

(streamlined contracting procedures)

Utilizes current CETSC staff for technical project

management and oversight of RCx contracting

partners

Utilizes National Environmental Balancing Bureau

(NEBB) RCx guide as source document

CETSC Goals

and

Challenges

Goals

• Optimize energy use while preserving capacity to

meet mission requirements and needs of spaces

Challenges due to Facility Systems Designed For:

• Mission

• Full operational and personnel capability

• Integrating needs of operations, public works, and

IH directorates

Drivers

• Executive Order

• Rising Costs

• Energy Independence / Security

Retro-Cx

Program

Started in 2008

• Installations Included in the Program

• ~178 Installation Sites

Performed Retro-Cx:

• 36 Installations

• 221 Facilities

• 6,322,336 Square Feet

Reasons for

Retro-Cx at

ANG Bases

Executive Order 13423

• 3% Reduction in energy usage per year for 10

years

• Starting in 2005 (total of 30%)

• Current Reduction Target through 2010 – 15%

• Primary energy use: electricity, natural gas, fuel

oil

Reduce Energy Costs for Installations

Improve Functionality of Systems and Comfort

What is

Retro-Cx?

Retro-commissioning is the application of the

commissioning process to existing buildings. Retrocommissioning

is a process that seeks to improve how

building equipment and systems function together.

In all, retro-commissioning improves a building’s

operations and maintenance (O&M) procedures to

enhance overall building performance.

Started on 11/2010

Expected Completion – 120 Days After Kickoff

Mission and Current Facility Requirement Understanding

Retro-Cx Ongoing at Both Bases

Stratton - Functional

Testing Complete

Stewart - Currently in

Monitoring Phase

Initial

Findings

Stratton

• VAV boxes set in fixed positions

• Night Setback of systems not functioning

properly

• Preventive maintenance not typically

complete

Stewart – Functional Testing Not Completed

• Ongoing energy projects on base

• High lighting intensity in some areas

• Large hangers present difficult areas to

maintain comfortable temperature, and bring

back to temperature after door opening

Timeline

Setbacks or

Delays

Stratton:

– Equipment not on during testing, postponed some

testing until May

Stewart:

– Security of Installation

– Access to HVAC staff

Seasons and Staff Availability Impact Delivery Timelines

Security Badge Issues

CETSC Program

Accomplishments

Analysis (FY 08)

• RCx’d Facilities: 59

• RCx’d Sq Ft: 1.79M SF

• RCx Cost: $2.95M

• Projected Annual Electric/Gas Saved From FY08 :

$450K

• Simple Pay Back: 6.5 years

• Cost/Sq Ft is decreasing with SOW refinement
