Why This Matters
Solar heat gain through windows accounts for 25–30% of residential cooling load in California homes. That's the single largest controllable source of summer heat gain.
Near Senior Hall in Berkeley, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
California's Title 24 energy code sets minimum window performance standards for new construction. Window film can bring older homes up to — and beyond — those standards at a fraction of the cost of window replacement.
The Solution
Film selection for south- and west-facing windows should prioritize solar heat rejection. For north-facing windows, UV protection and glare control are typically the primary goals.
Ceramic film is the premium option: non-metallic, signal-transparent, and highly effective at blocking solar energy. It costs 20–40% more than standard films but offers superior clarity and a longer lifespan.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
Climate & Solar Performance
Properties near Senior Hall in West Berkeley, Berkeley experience low-e glass performance conditions that make window film particularly effective. Anti-Reflective Window Film is specifically engineered to address this solar exposure.
