Save on Energy Bills with Modern, Insulated Windows
Upgrading to energy-efficient replacement windows is a smart investment for Berkeley homeowners, with real energy savings and better comfort all year.
How New Windows Reduce Energy Costs
Older single-pane windows let heat pass through, raising heating and cooling needs. Modern double- or triple-pane windows, filled with insulating gases like argon or krypton, limit that heat exchange.
California Title 24 Energy Efficiency Requirements
California’s Title 24 energy code sets firm standards for windows. The 2022 standards call for a maximum U-Factor of 0.30 and a Solar Heat Gain Coefficient (SHGC) of 0.23 or lower, which measure heat loss and heat gain.
Tax Credits & Rebates for Energy-Efficient Upgrades
Energy-efficient windows may qualify you for federal tax credits and local rebates that offset upfront costs. Check with your local utility, such as PG&E, for current programs.
