SIMEA Stato dell’arte energetica degli edifici 1.2.27.6. Output 54 Doc.No 20100610.SIMEA.MR.03 Versione 1 Graphical summary reports provide a single-run results summary, a comparative results summary (compares results from multiple separate building simulation runs), and parametric tabular reports (compare annual results by endues, incremental or cumulative results). Additional output includes input/output summary reports (rule-of-thumb and other indices), nonhourly simulation results (tabular/text DOE-2 SIM file reports), hourly simulation results (text and commaseparated variable hourly listings for thousands of simulation variables), and California Title 24 compliance analysis reports. 1.2.27.7. Computer Platform Microsoft Windows 98/NT/2000/XP/Vista 1.2.27.8. Programming Language Interface: C++, DOE-2.2 engine: FORTRAN 1.2.27.9. Strengths The unique strength of eQUEST is that it is an energy performance design tool that evaluates wholebuilding performance throughout the entire design process. Its wizards (schematic, design development, and energy efficiency measure) make it possible for any member of the design team to explore the energy performance of design concepts from the earliest design phase. Its detailed interface (a full-featured Windows front-end for DOE-2.2) supports detailed analysis throughout the construction documents, commissioning, and post occupancy phases. Its execution speed makes it feasible to perform many evaluations of large models, capturing critical interactions between building systems at the whole-building level. Its rule-based processor provides intelligent dynamic defaults in the interface and enables automated quality control checks of simulation inputs and results and automated Title 24 compliance (certified by the California Energy Commission for use with the 2001 and 2005 Title 24 compliance analysis). 1.2.27.10. Weaknesses Defaults and automated compliance analysis has not yet been extended from California Title 24 to ASHRAE 90.1. It does not yet support SI units (I-P units only). Ground-coupling and infiltration/natural ventilation models are simplified and limited. Daylighting can be applied only to convex spaces (all room surfaces have an unrestricted view of each surface) and cannot be transmitted (borrowed) through interior glazed surfaces. Custom functions in DOE-2.1E (allows users limited customization of source code without having to recompile the code) have not yet been made available in DOE-2.2 or eQUEST.
SIMEA Stato dell’arte energetica degli edifici 1.2.28. ESP-r 55 Doc.No 20100610.SIMEA.MR.03 Versione 1 General purpose simulation environment which supports an indepth appraisal of the factors which influence the energy and environmental performance of buildings. The ESP-r system has been the subject of sustained developments since 1974 and in 2002 converted to the GNU Public License. ESP-r has the objective of simulating building performance in a manner that: a) is realistic and adheres closely to actual physical systems, b) supports early-through-detailed design stage appraisals, and c) enables integrated performance assessments in which no single issue is unduly prominent. ESP-r attempts to simulate the real world as rigorously as possible and to a level which is consistent with current best practice in the international simulation community. By addressing all aspects simultaneously, ESP-r allows the designer to explore the complex relationships between a building's form, fabric, air flow, plant and control. ESP-r is based on a finite volume, conservation approach in which a problem (specified in terms of geometry, construction, operation, leakage distribution, etc.) is transformed into a set of conservation equations (for energy, mass, momentum, etc.) which are then integrated at successive time-steps in response to climate, occupant and control system influences. ESP-r comprises a central Project Manager around which are arranged support databases, a simulator, various performance assessment tools and a variety of third party applications for CAD, visualization and report generation. In keeping with the philosophy of linking ESP-r to other modelling systems, users can now export to EnergyPlus an ESP-r model with materials, constructions, surfaces (all three and four sided surfaces as well as those including one window or one door - more complex surfaces are omitted). Boundary condition attributes are translated and the parent/child relationship between opaque and transparent surfaces established. The exported models usually pass the EnergyPlus parser with no errors or with minor warnings. Currently, approximate optical properties are established and schedules are not yet included. 1.2.28.1. Validation/Testing ESP-r has been extensively validated. See Strachan P A. 2000. 'ESP-r: Summary of Validation Studies', ESRU Technical Report, University of Strathclyde, Glasgow. for more information. 1.2.28.2. Expertise Required Understanding of thermo-physical processes in buildings, environmental systems and controls. 1.2.28.3. Users Hundreds of users, primarily in Europe and Asia. 1.2.28.4. Audience Engineers, researchers, architects, energy consultants. 1.2.28.5. Input Building geometry can be defined either using CAD tools or in-built facilities. ESP-r is compatible with the AutoCAD and ECOTECT which can be used to create a building representation of arbitrary complexity. Models can be exported to other assessments tools such as TSBI3 and Radiance. Constructional
