The table below shows the most common sources of heat gain in Arizona according to SRP.

Windows                       48%
Walls and Doors           19%
Activities and People   14%
Weatherization             13%
Ceiling                              6%

Surprising?  A couple years ago I would have told you that air or duct leakage would be at the top, and it may be for your home depending on age, construction defects, orientation and a number of other factors.  A good energy auditor will be able to prioritize the sources of your home’s heat gain, which is the basis for an effective game plan to reduce utility bills, increase comfort and improve indoor air quality.
