“Cool roofs are ready to save energy, cool urban heat islands, and help slow global warming… Cool roofs are one of the quickest and lowest cost ways we can reduce our global carbon emissions and begin the hard work of slowing climate change… By demonstrating the benefits of cool roofs on our facilities, the federal government can lead the nation toward more sustainable building practices, while reducing the federal carbon footprint and saving money for taxpayers.” said Secretary Chu. “
The Secretary today also issued a letter to the heads of other federal agencies, encouraging them to take similar steps at their facilities. To offer additional support for federal and commercial building operators that are looking to install cool roofs, DOE released its Guidelines for Selecting Cool Roofs, which provides technical assistance on types of roofing materials and how to select the roof that will work best on a specific facility. The Federal government has written a Guideline for Selecting Cool Roofs in July 2010. The DOE in July 19, 2010 stated Review the complete Guidelines for Selecting Cool Roofs (pdf – 909 kb).
President Obama and Secretary Chu have made clear that the federal government should play a leading role in moving the nation toward a more sustainable future. Under President Obama’s Executive Order on Sustainability, the federal government has committed to reducing its greenhouse gas emissions 28 percent by 2020. As part of that effort, Secretary Chu has directed all DOE offices to install cool roofs, whenever cost effective over the lifetime of the roof, when constructing new roofs or replacing old ones at DOE facilities. With cool roofs, these federal buildings will consume less energy, offset additional carbon emissions, and save taxpayers money. Read Secretary Chu’s memorandum (pdf – 395 kb).
The National Nuclear Security Administration (NNSA) has already installed more than two million square feet of cool and white roofs at NNSA sites across the country. Through the Roof Asset Management Program (RAMP) NNSA currently saves an average of $500,000 a year in energy cost and expects to save more than $10 million over the next 15 years. Overall, NNSA has reduced building cooling and heating cost by an average of 70% annually on reroofed areas by installing cool roofs and installing insulation.
