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.
