“Cool” Roof Retrofit Earns Praise for Energy Efficiency

By: John Ryan, Metal Construction Association

Sometimes the word “cool” can be a bit overused–but not in the case of this recent metal roof retrofit project with the U.S. Air Force’s Goodfellow Air Force Base in Texas. This roof is cool–both literally and figuratively.

In 2010, a team of leading metal construction companies and the Metal Construction Association (MCA) were awarded a $1 million Environmental Security Technologies Certification Program (ESTCP) grant to develop a retrofit metal roof system with integrated renewable energy technologies, including an integrated assembly of six different roofing system components.

The Department of Energy’s Oakridge National Laboratory will soon be analyzing a full year’s worth of data on heat transfer, energy output from the photovoltaic panels and water usage from the building. MCA expects that the results will be positive, and the Air Force reports that preliminary numbers how a 44-percent reduction in energy consumption.

Stay tuned for the full report and results in the coming months from this “cool” project.
