 Because cool roofs save both money and energy, in October 2005 they became part of the prescriptive requirements of California's energy code, the Title 24 Building Energy Efficiency Standards. This highly effective initiative has yielded a favorable reduction in per capita energy usage. Learn more about California Title 24 and cool roofs here. |
White TPO and PVC exceed requirements of Section 118 of Title 24, requiring all commercial roofs to meet a baseline value of 0.70 for solar reflectance and 0.75 for thermal emittance |
 Established in 1998, the Cool Roof Rating Council (CRRC) is an independent, non-profit organization that maintains a third-party rating system for radiative properties of roof surfacing materials. Dow Roofing Systems is a Class "A" Charter Member of the CRRC. Visit www.coolroofs.org for more information. |
TPO and PVC membranes consistently exceed CRRC energy requirement |
 An ENERGY STAR qualified roof product is a reflective roof product that lowers roof surface temperature by up to 100°F, thereby decreasing the amount of heat transferred to a building's interior. ENERGY STAR qualified roof products save money and energy by reducing the amount of air conditioning needed to keep a building comfortable. Dow Roofing Systems is a charter member of the ENERGY STAR roof products program. Learn more and view ENERGY STAR qualified products from Dow Roofing Systems here. |
TPO and PVC membranes meet or exceed requirements for low- and steep-slope roofs |
 The Montreal Protocol and the U.S. Environmental Protection Agency (EPA) established a deadline for eliminating chlorofluorocarbons (CFCs) and converting to less environmentally harmful hydro-chlorofluorocarbons (HCFCs). This conversion was completed in 1994 but was only a transitional stage to be followed by a ban on production and importation of HCFCs used in foam plastic roof insulation and other products. Inventors of HCFC-free TERMICO™ polyisocyanurate insulation were awarded the prestigious U.S. EPA Stratospheric Ozone Protection Award in 1998. For current information about the Montreal Protocol, visit www.ozone.unep.org |

 The U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System is the nationally accepted benchmark for the design, construction and operation of high-performance green buildings. As a member of the USGBC, Dow shares a common goal in transforming the way buildings are designed, built and operated – for a more sustainable future. Incorporating Dow Roofing Systems products into building designs can help obtain LEED credits in several categories. For more information about how Dow Roofing Systems products and systems can help you earn credits toward LEED certification, download the Dow Roofing Systems, LEED and Sustainable Roof Assemblies Information Sheet (372KB PDF) or contact us. |
