This tool characterizes the shading performance of BrightShade
window systems. Each BrightShade
configuration may be evaluated for a specific location and façade orientation.
This tool makes several simplifying assumptions, most notably clear sky conditions, and a simplified model for diffuse radiation. The values obtained are for general design and not for engineering purposes.
Please click on the name of any input for specific instructions. After the inputs are set, click the "recalculate" button. The chart will display the shading performance of the window for each hour of the day for each month of the year. The "energy savings" column will display an estimate of the avoided heat gain resulting from the shade provided by the window. The shading and avoided heat values are relative to a typical glass jalousie window.
