Installation of a “cool roof” can be a great way to reflect sunlight rather than having a building absorb it, thereby reducing a building’s thermal load, saving energy, money, improving building comfort, and reducing greenhouse gas emissions. To provide guidance on what it takes for a roof to be considered a cool roof, the CEC has put together a presentation, viewable here.
Looking for more information on cool roofs? Check out this Cool Roofs 101 page from the Cool Roof Rating Council (CRRC). A useful summary on financing and incentives for cool roofs – including PACE financing, and incentives offered by PG&E, SCE, Sacramento Municipal Utility District (SMUD), Riverside Public Utilities, Los Angeles Department of Water and Power, and Anaheim Public Utilities – is available here on CoolCalifornia.org’s website.
