Cool roofs—those with reflectance and emissivity that make them good at keeping out the sun’s heat—are recommended widely without much regard for climate or project specifics. They’ve been adopted into multiple energy codes, and the concept even has its own bill in the U.S. Senate. But it turns out that, beneath one of the least controversial green building recommendations, a debate is raging.

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.” 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.

Overall, buildings are responsible for more than one-third of global energy consumption. While whole-building approaches are ideal, every day building envelope components are upgraded or replaced using technologies that are less efficient than the best options available. These advanced options, which are the primary focus of this roadmap, are needed not only to support whole-building approaches but also to improve the energy efficiency of individual components.
