DOE Implements Cool Roofs Initiative Across Federal Government
Cool roofs will reduce energy use, limit carbon pollution and save taxpayer money.
U.S. Department of Energy Secretary Steven Chu today announced a series of initiatives underway at the Department of Energy to more broadly implement cool roof technologies on DOE facilities and buildings across the federal government.
Cool roofs use lighter-colored roofing surfaces or special coatings to reflect more of the sun’s heat, helping improve building efficiency by reducing cooling costs and offsetting carbon emissions.
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).
“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,” said Secretary Chu. “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.”
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.

Roofs and road pavement cover 50 to 65 percent of urban areas. Because they absorb so much heat, dark-colored roofs and roadways create what is called the “urban heat island effect,” where a city is significantly warmer than its surrounding rural areas.
Cool roofs significantly reduce the heat island effect and improve air quality by reducing emissions. A recent study by researchers at Lawrence Berkeley National Laboratory (LBNL) found that using cool roofs and cool pavements in cities around the world can help reduce the demand for air conditioning, cool entire cities, and potentially cancel the heating effect of up to two years of worldwide carbon dioxide emissions.

DOE is also expanding its research activity for cool roofs to enable technological innovation and guide policy implementation. The research effort includes developing advanced testing protocols, conducting urban heat island analyses, and undertaking studies to further quantify the direct global cooling benefits associated with cool surfaces.
The Department also anticipates awarding new projects to develop higher performing, new innovative roofing materials under the Department’s Small Business Innovation Research grant program.
