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...

We can even go this one better with green roof designs. But light is preferable to dark when it comes to surfaces in our hot climate (this is why adobes were white washed). Our most energy-intensive season is the the hottest period at end of summer/early fall months, with most of that energy going into air conditioning to cool heated buildings.
Great to see LA becoming a leader in requiring cool roofs that cost no more.
