Last spring, my wife and I installed Betterliving exterior solar shades on the south facing side of our home. What a difference they made! They reduced glare, reduced heat near the window, and reduced air conditioning costs!
Exterior solar shades reduce the house heating and cooling energy use
Yesterday, the Canadian National Research Council published a scientific report, which concludes:
“Exterior insulating rollshutters and close-weave screens are the most effective shading devices to reduce the house heating and cooling energy use, the on-peak cooling power demand, and the risk of moisture condensation on the interior surfaces of windows. They were also shown to improve the thermal comfort conditions near windows (e.g., window interior surface temperatures are several degrees higher with rollshutters than with typical interior blinds).”
