Cool Roofing & Energy Efficiency

“We strongly oppose any recommendation that irresponsibly promotes the use of one product over another based on faulty science. We question the validity of this study, since it is based on a sample size of only 22 roofs, and we… Read More

The EPDM Roofing Association (ERA) is challenging a study released by the Lawrence Berkeley National Laboratory, which cites white roofs as the most “cost-effective” roofing option over a 50-year time span. The study, published in the March, 2014, issue of… Read More

Urban areas are hot spots that drive multisector environmental change (1, 2). Consumption and production of resources for use within urban environments have local and remote implications for ecosystem services, hydroclimate, energy provision, health, and other factors of human wellbeing… Read More

Lawrence Berkeley National Laboratory has released a study titled: “Economic Comparison of White, Green, and Black Flat Roofs in the United States.” The EPDM Roofing Association is challenging this study. To help provide clarity regarding roofing system choice, and to… Read More

Article The use of white, reflective roofing materials throughout the United States has grown in popularity in recent years, but are these assemblies really ideal for all locations? When specifying roofing material color for a northern climate, it is important… Read More

During the past 15 years, reflective, or “cool,” roofs have been promoted as an effective way for building owners to save energy and lower utility costs while reducing a building’s carbon footprint. The belief white roofs always are the most… Read More

“Flat roofs generally have a high potential of nightly overcooling and, therefore, an increased risk of condensation within the construction, particularly in cold-climate zones, depending on their specific assembly. A white exterior surface or so-called “cool roof,” applied to decrease… Read More

“When designing a roof system membrane color, in addition to other variables such as building conditions, insulation levels and local weather conditions must be considered in order to prevent moisture condensation and subsequent accumulation within the assembly.”

A team of researchers from Arizona State University have found that warming resulting from megapolitan expansion is seasonally dependent, with greatest warming occurring during summer and least during winter. Among the most practical ways to combat urbanization-induced warming – the… Read More

Although an overall world population increase of 2.3 billion is projected by 2050 relative to 2011, urban growth is estimated at 2.6 billion, as urban complexes, in addition to absorbing all of the world’s additional inhabitants, are expected to draw… Read More
