Choosing the most efficient window design for a commercial building can be difficult. Product information typically offers window properties, such as U-factor, Solar Heat Gain Coefficient, and Condensation Resistance. However, the relative importance of these properties depends on site- and building-specific conditions.
Here you can compare performance data between a set of Wausau products, and get building performance information on annual energy, peak demand, carbon emissions, daylight, glare, and condensation.
This tool was developed by John Carmody and Kerry Haglund, researchers at the Center for Sustainable Building Research at the University of Minnesota. All simulations were done using COMFEN software, developed by the staff at the Windows and Daylighting Group at Lawrence Berkeley National Laboratory.
