ENERPASS
Detailed building energy simulation program for residential and smaller commercial buildings. ENERPASS calculates the annual energy use for space heating, cooling, lighting, water heating and fan energy. The calculations are performed on an hourly basis using hourly measured weather data. ENERPASS can model up to seven building zones and provides hourly temperature and humidity predictions for each zone. A wide range of HVAC systems can be modelled including make-up air units, heat recovery ventilators, rooftop units, VAV, four-pipe fan coil, and dual duct. The program uses full screen data entry in an easy-to-use format. A typical building model can be generated in one to two hours. In IEA validation studies ENERPASS results compare favorably with other hourly based computer programs.
Keywords
energy performance, design, residential and small commercial buildings
Validation/Testing
N/A
Expertise Required
A general understanding of building construction is required.
Users
Hundreds of builders, architects and researchers primarily in North America.
Audience
Building designers and specifiers can use ENERPASS to design more energy efficient buildings.
Input
Users must enter areas and R-values of walls, windows, etc and the characteristics of the HVAC and lighting systems. The program includes libraries of standard construction assemblies and equipment.
Output
Annual energy use and cost; includes histograms of temperature, humidity and light levels. Hourly results can also be displayed.
Computer Platform
PC-compatible 386 or higher, DOS, Windows 3.1 or 95.
Programming Language
C and FORTRAN
Strengths
Easy and quick data entry. Hourly calculation of results.
Weaknesses
The program is limited to seven zones and cannot handle large complex buildings such as hospitals.
