SDG&E Rebates & Energy Savings From Home Window Film in San Diego
Key Takeaway
Residential window film can reduce home cooling load by 25 to 35 percent in San Diego climates. SDG&E offers energy efficiency rebates through programs published on sdge.com, and California Title 24 building energy code recognizes window film as a qualifying retrofit. The U.S. Department of Energy and Energy Star both list window film as a recommended retrofit for hot-climate homes.
San Diego homes face one of the highest cooling loads in coastal California. Residential window film is one of the few retrofits that pays back through both immediate comfort and ongoing utility savings — and several of those savings are subsidized by SDG&E and California state programs.
