DOE-2 Energy Modeling Summary - Office Building
The following report summarizes the energy use simulations performed for the GSA LEED Cost
Study Office Building models, using the computer program DOE2.1-E. Simulations were
developed for both the minimal facade renovation and full facade renovation variants of the
Office Building. The report includes the following information:
1) A description of the "baseline" buildings, including the building geometries, construction
assemblies, building systems, schedules, and utility rates.
2) A comparison of the baseline buildings to a LEED Reference Case that meets the
minimal prescriptive requirements of ASHRAE/IESNA 90.1-1999.
3) A description of the individual Energy Efficiency Measures (EEMs) simulated to achieve
energy savings beyond the Baseline cases.
4) A listing of the combined EEMs that were assembled to achieve three, five, and seven
energy points (minimal facade renovation), or five and eight energy points (full facade
renovation) under LEED credit EA-1, Optimize Energy Performance.
5) Energy Cost Budget forms to document the points earned under credit EA-1.
A. GENERAL INFORMATION
