Seek Shade
Landscaping can do more than boost curb appeal. With thoughtfully chosen, strategically positioned trees and shrubs, you can actually keep your house cooler through the summer. After all, virtually all parts of the home exterior let in heat. To limit the effect, shade the roof with dense-canopied trees, ideally placed on the southern portion of the property. Also, deflect late afternoon sun with short trees, tall shrubs, or planted trellis-work situated along the western exposure.
Install Awnings
Of course, trees and shrubs can take years to mature. If yours are still too young to lend adequate shade, don't fret: Awnings achieve similar results, and they do so more or less instantly. Sure, not everyone loves the look of awnings, but few would argue against their effectiveness. Installed over a west-facing window, a fabric awning can reduce heat gain by as much as 77 percent! It's a simple concept, really: Block out the harsh sun to enjoy cooler spaces indoors.
Shield Your Windows
Go even further to reduce solar heat gain by applying reflective, heat-control window film to any windows in the hot room (or, if you choose, throughout the entire house). Made up of multiple UV-blocking layers, insulating window films limit the extent to which the sun's rays can drive up the temperature indoors. Because they're usually self-adhering, applying window film couldn't be easier. The process requires little more than a tape measure and a pair of scissors.
Focus on Fans
Don't underestimate the humble fan. In low humidity, a strategically placed fan can make you considerably more comfortable. On the sunny side of the house, particularly on upper floors, position fans to blow out toward an open window. On the shady side of the house, particularly on lower floors, do the opposite—orient fans to blow in toward the living spaces. In the summer, set ceiling fans to rotate counterclockwise so cool air gets drawn up from the floor.
