Cool roofs in Los Angeles
Los Angeles, the second most populous city in the U.S., has made history by becoming the first major city to require all new and refurbished homes have a "cool roof." On December 17, 2013 the Los Angeles City Council unanimously passed an update to its Municipal Building Code. A cool roof is one that "reflects and emits the sun's heat back to the sky instead of transferring it to the building below," according to the Cool Roof Rating Council.
A white roof can reflect 80 percent of sunlight in the summer. A cooler building in the summer means less air conditioning is used and that saves homeowners money.
Those other benefits include improving air quality by reducing the formation of ozone, reducing greenhouse gas emissions, and decrease roof maintenance costs.
