Home Age & Window Efficiency San Gabriel
The median home in San Gabriel 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.
San Gabriel is a heating-dominated climate (3,162 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.

For Window Installation, the payback is the headline: DOE estimates drafty or single-pane windows account for 25–30% of heating and cooling energy use — about $581 per year in avoidable cost at California's 32.54¢/kWh (EIA, 2025). In this warm zone (USDA Zone 10), prioritize low SHGC (≤ 0.25) to block summer solar gain — the dominant load — with a low-e coating that reflects infrared.
