ENER-WIN
Energy design tool for large commercial buildings. Performs whole-building energy analysis for 8760 hours/year for up to 98 zones and 20 different wall and window types. Calculates transient heat flows, HVAC loads, daylighting, energy consumption, demand charges, life-cycle costs, and floating temperatures in unconditioned zones. Input is through a sketching interface. Weather data from included database of 1500 cities. Graphical output is in form of bar charts and graphs. Tabulates peak zone loads and air quantities.

Validation/Testing
Soebarto, Veronica I. 1997, �Calibration of hourly energy simulations using hourly monitored data and monthly utility records for two case study buildings�, Proc. Building Simulation �97, Vol. II, Int�l. Bldg. Perf. Simulation Ass�n (IBPSA) Conf. held in Prague, the Czech Republic, pp 411-419, 8-10 Sept 1997
Expertise Required
Experience with Windows applications. Knowledge of building thermal properties and energy concepts.
Users
Estimated to be in the low hundreds at schools of architecture in Greece, Mexico, Thailand, and the U.S., as well as several dozen practitioners in the U.S., Canada, Kuwait, Mexico and Europe.
Audience
Architects, engineers, energy analysts, building inspectors, and students of architecture and engineering.
Input
Graphic entry of building plans through a sketch interface, building envelope thermal properties, hourly use profiles, hourly indoor temperature settings.
Output
Tabular reports and graphs available for monthly loads, annual loads and energy, peak loads, electric displacement by daylighting, life-cycle costs, and weather summaries.
Computer Platform
PC-compatible, MS Windows (All versions), 64 Mbytes RAM, 30 Mbytes of available hard drive. Screen resolution 1024x768 minimum.
Programming Language
Visual Basic and FORTRAN.
Strengths
Graphic sketch input interface, hourly weather data generator with 1500-city worldwide database. Can run in compacted weather data mode for quick testing of alternative design strategies. Generous use of defaults for materials, windows, profiles, costs, lights, etc.
Weaknesses
Uses simplified system simulation algorithms. Nine HVAC systems available. Not recommended for testing differences in HVAC systems.
