A simulation-based tool developed to allow the DOE Institutional Conservation Program (ICP) staff and participants to reliably determine the energy savings directly attributable to ICP-supported retrofit measures implemented in a building. RESEM (Retrofit Energy Savings Estimation Model) calculates long-term energy savings directly from actual utility data, with corrections for weather and use variations between the pre-retrofit and post-retrofit utility data collection periods.
retrofit, institutional buildings
Moderate level of computer literacy; familiarity with building energy concepts.
Building managers and energy retrofit engineers.
Minimal required input includes: original year of building construction, total floor area, building type, utility data for both pre- and post-retrofit periods, and a description of the installed retrofit measures. Detailed building component description data may also be entered. All data are entered and viewed through a DOS-based graphical user interface.
Long-term energy consumption and retrofit savings for each fuel type.
PC-compatible running MS-DOS.
C with third party user interface library
Interactive user interface tailored to the retrofit energy savings estimation process, complete simulatable building description generated from minimal user input, fast embedded simulation engine, semi-automated process for tuning building simulation to measured utility data, numerous retrofit measures can be automatically applied to the building description.
Restricted to standard 640K of RAM.
