Shade Your Windows!
Now, there are two ways to shade your windows. We can shade them from the outside, or the inside. Between the two, shading from the outside is much more effective than from the inside.
 
     

When we shade the windows from the inside (blinds, curtains..etc), we are only partially shading the house. The sunlight hits the windows and heats them up, it then enters the room and heats up the shading devices and the space between them and the windows. (See drawing) Think you are shading your house? Think again! These three elements (window glass, shading devices and the space in between) act like a heater and constantly heat up your house.

Exterior shading devices, however, stop the light before it touches your windows. And because the shading devices are installed outside your house, the constant airflow takes away the heat on the shading devices. The heat never has a chance to come inside your house, not even onto your windows!
