Home Age & Window Efficiency Louisville
The median home in Louisville was built in 1969, placing the local housing stock in the very likely single-pane category. Windows original to construction are almost certainly single-pane glass — a significant source of heat loss in winter and heat gain in summer. The DOE estimates single-pane windows account for 25–30% of home heating and cooling energy loss in older homes. Source: U.S. Census Bureau, American Community Survey, median year structure built.
Louisville is a heating-dominated climate (4,207 annual heating degree days) — window insulation has a larger impact on winter energy bills. The DOE estimates that replacing single-pane windows in a heating-dominated climate can reduce heating energy use by 21–31% and cooling energy use by 11–22%. In a cooling climate, solar-control low-e windows can reduce cooling load significantly.

Custom Windows & Energy Costs — Kentucky
For Custom Windows, getting the glazing spec right for the climate is what separates a custom window that performs from one that just looks good. In this mixed climate (USDA Zone 7), DOE recommends U-factor ≤ 0.32, SHGC ≤ 0.40 — double-pane low-e balances winter retention and summer solar gain. At Kentucky's 13.24¢/kWh, the right U-factor/SHGC choice avoids roughly $236/year in energy loss versus old windows.
