UNDER LA’S NEW COOL ROOFS ORDINANCE, ALL NEW OR RENOVATED BUILDINGS MUST HAVE REFLECTIVE ROOFS (HEAT ISLAND GROUP – LAWRENCE BERKELEY NATIONAL LABORATORY)
What’s the coolest place in Los Angeles? It may be right over your head. Starting in 2014, thanks to an update of the Municipal Building Code, all new or refurbished buildings will be equipped with “cool roofs.” A cool roof is built of reflective rather than absorptive material. Compared to traditional roofs, cool roofs can be as much as 50 degrees cooler on the roof surface, and can lower interior building temperatures by several degrees. Los Angeles is the first major American city to pass a cool-roof ordinance.
