RESEM

RESEM logo.

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.

Keywords

retrofit, institutional buildings

Validation/Testing

N/A

Expertise Required

Moderate level of computer literacy; familiarity with building energy concepts.

Users

Over 50.

Audience

Building managers and energy retrofit engineers.

Input

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.

Output

Long-term energy consumption and retrofit savings for each fuel type.

Computer Platform

PC-compatible running MS-DOS.

Programming Language

C with third party user interface library

Strengths

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.

Weaknesses

Restricted to standard 640K of RAM.
