Home Building Efficiency Report
← Change Location
Graham County, Arizona is located within the Warm Dry climate zone, which also has the designation of #3B. The US Department of Energy has split the United States into eight zones to help in creating optimal building practices to achieve the most energy savings within homes.
A warm-dry climate is defined as a region that receives less than 20 inches (50 cm) of annual precipitation and where the monthly average outdoor temperature remains above 45°F (7°C) throughout the year.
This region is considered "dry" based on a calculation involving the area's amount of precipitation and its annual mean temperature. The calculation is 0.44 x (TF – 19.5), where TF is the annual mean temperature in °F. If the annual precipitation is less than the equation, it’s a dry climate.
Best Energy Saving Products
We've outlined a handful of building products that should be tailored for homes specifically in your Arizona county. We detail the recommendations, how to interpret them, and then some of the more popular brands that meet or exceed those energy-saving standards.
Windows in Graham County are expected to have a U-Factor of 0.3 or less. The lower the U-Factor value of a window, the better it is at keeping heat inside the home.
The expected Solar Heat Gain Coefficient (SHGC) of windows installed in Graham County should be equal to or less than 0.25. This value measures how well a product can resist unwanted solar heat gain, which is important in the warmer summer months.
| Climate Zone | Window U-Factor | Skylight U-Factor | Glazed SHGC | Air Leakage |
|---|---|---|---|---|
3B – Warm Dry |
0.3 | 0.55 | 0.25 | ≤5 |
Any new or replacement window will be better at preserving energy than an old leaky one. Double paned windows with argon gas are the most energy efficient, but also the most expensive.
