comptuer code: THERM, WINDOW, Optics, RESFEN at LBNL

RESFEN --A PC program for calculating the heating and cooling energy use of windows in residential buildings

WINDOW : for analyzing window thermal and optical performance

THERM: for analyzing two-dimensional heat transfer through building products. "THERM..Windows-based computer program for use by building component manufacturers, engineers, educators, students, architects, and others interested in heat transfer. Using THERM, you can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors; appliances; and other products where thermal bridges are of concern. THERM's heat-transfer analysis allows you to evaluate a product's energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity."

Optics5 : for analyzing optical properties of glazing systems

International Glazing Database : Optical data for glazing products used by WINDOW 5.2 and Optics5.1 including NFRC approved products.

Center for the Built Environment, U of Berkeley

mission is to improve the design, operation, and environmental quality of buildings by providing timely, unbiased information on building technologies and design techniques.
