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.
View the video above or read MCA’s case study to learn more about the project’s energy-efficient technologies, which include photovoltaics to generate electricity, solar-thermal technologies for domestic hot water and space heating, and rainwater capture for irrigation.
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.

Fortune Magazine recently featured a story about Starbucks’ use of shipping containers in the design of their new drive-through coffee shops. According to Fortune, a good portion of the 900 or so drive-through locations that Starbucks plans to build in the next five years will be made using retrofitted metal shipping containers.
The use and repurposing of metal shipping containers in construction is a growing trend, even though they are not always less expensive than other manufacturing methods. And re-using a metal shipping container that would otherwise be destined for the scrap heap can make a statement about sustainability, especially when used with other “green” building efficiencies.
MCA’s 2012 Chairman’s Award Winner in the Education-Colleges & Universities category is a creative example of how shipping containers can be used in construction. The project, a student center for Monterrey Technical University in Juarez, Mexico, was designed by Ruben Escobar, a graduate of MTU and principle at the architecture firm Grupo ARKHOS.
The student center uses 14 metal shipping containers to make a 7,000 sq. ft. space for students to interact socially. With exposed metal making up 80% of the new building’s structure, Escobar integrated a metal skin composed of Reynobond composite aluminum panels around the building’s entrance. The 4-mm panels from Alcoa Architectural Products proved to be a perfect complement to the shipping containers, and also were chosen for their durability.
Not only is the new building constructed primarily of recycled materials, but it also is designed to keep cooling costs low. An outdoor paint scheme that uses automotive paint mixed with ceramic nanospheres helps repel the desert sun’s rays, and a series of aluminum and glass garage doors open up to provide natural ventilation about 8 months out of the year.
It is estimated that there are more than 17 million shipping containers in the world today. Because the United States imports far more than it exports, there is a surplus of empty shipping containers in this country. Metal shipping container-inspired architecture is just one way to give new life and purpose to these resources.
Attending the Energy Efficient Roofing Conference in Charlotte, NC, next week? Don’t miss Scott Kriner’s presentation on the integrated energy efficient metal roof retrofit system at Goodfellow Air Force Base, San Angelo, TX.
“This Department of Defense (DOD) demonstration project is a result of the $1 million Environmental Security Technology Certification Program grant, which was awarded to a team of industry professionals representing metal roofing, retrofitting, solar technologies, insulation, and the Metal Construction Association (MCA),” said Kriner, MCA technical director. Results of the installation are expected later this year.
The United States Department of Defense (DOD) is a leader in energy efficiency for good reason—it is mandated to reduce energy use on its properties by 30% by 2015 and by another 37.5% by 2020. Three years ago, a team of leading metal construction companies and the Metal Construction Association (MCA) were awarded a $1 million grant to develop a retrofit metal roof system for a DOD building with integrated renewable energy technologies. Today, Goodfellow Air Force Base in San Angelo, TX, boasts a retrofit metal roofing system that integrates a host of solar energy-saving technologies and the ability to capture rainwater for irrigation purposes. View the case study of the project for more complete information.
The Department of Energy’s Oak Ridge National Laboratory (ORNL) is monitoring the building’s temperature and heat information. According to Scott Kriner, MCA technical director, both the DOD and the project team “are confident that this integrated retrofit roof system will perform as predicted and allow for the technology to be transferred throughout the DOD, to other federal agencies, and into the commercial-building sector.”
ORNL should be completing a year-long study of the building’s energy data in 2013 to quantify the impact of the metal roof retrofit project. Stay tuned–we will post more information to this site as it becomes available.

If anyone understands long-term life cycles, it’s a cemetery owner. I know one in St. Louis, MO, who owns two large, old mausoleums that stand side by side. One mausoleum has steel and copper roof systems that have remained relatively maintenance- and repair-free—and beautiful—for as long as 80 years. The other mausoleum has a flat-roof addition, built in 1986, which has a conventional roofing system that has been plagued by leaks for decades.
After determining the life-cycle costing and return on investment on the two roofs, it’s not surprising that the owner decided to retrofit the flat-roof addition with a metal roof. He anticipates far fewer worries with a metal roof, given its ability to shed rainwater and its 40- to 60-year service life.
In addition to its longevity and durability, metal retrofit also offers long-term cost-savings in the form of appreciable value of the building, better insurance rates, and energy-efficiency. Adding insulation to a metal retrofit can provide R30 thermal resistance—one reason why you increasingly see them on military and municipal buildings, including schools. Many building owners choose to add renewable solar energy technologies to these roofs, such as photovoltaics or solar hot-water systems, which can reap huge tax benefits.
For designers and architects, metal retrofits add generous curb appeal to buildings. Architectural metal roofs are meant to be seen, and a stunning sloped metal retrofit is seen far and wide—and well into the future.
In a recent presentation at METALCON in Chicago, IL, Peter Pfeiffer, FAIA, principal, Barley & Pfeiffer Architects, Austin, TX, discussed some commonsense ideas for building and living green. Pfeiffer, a pioneer in green building who owns “the greenest house in America,” stressed the cost-effectiveness of conserving energy in simple ways, such as adjusting your sprinkler system, placing your electrical panel on an interior (instead of an exterior) wall, and having your roof act as a shading umbrella.
“Don’t underestimate the value of discussing the obvious,” said Pfeiffer. “R-value means little if the house leaks, windows are unshaded, or the roof is a dark color. This is obvious stuff.” He added that sensible green building is “smarter and better” because it results in “reduced consumption of stuff,” such as energy, water, and nonrenewable materials. This type of building also improves health and indoor air quality.
Pfeiffer stressed that producing your own power is expensive. “Shading windows is better than adding [high-maintenance] solar roof panels. Light-colored metal roofs with broad overhangs that shade windows save money and are easier to maintain.”
How do you accomplish green building? Pfeiffer stated, “Keep it simple and rely on smart, thoughtful, climate-sensitive design.” He said that gizmos and complex things break, and are expensive and time-consuming to fix. Instead, make practical changes to your house, such as using Energy Star dishwashers, low-flow showerheads, and less hot water (instead of buying a fancy water heater). Also, don’t use dark roofs in the South.
Pfeiffer is a proponent of cool metal roofing/ASV ventilation. Unlike conventional roofing insulation, ventilation makes the roof last longer because it doesn’t lock in moisture. A Galvalume metal roof with an airspace underneath keeps heat in the house, he said, and a metal roof costs more than shingles, but it provides long-term cost savings on energy and insurance.
Solar radiation is a “big, powerful thing—and it’s uncomfortable. You need overhangs. Retrofitting with window awnings cuts air conditioning loads by a third by reducing radiation.”

My daughter just started kindergarten this fall, and picking her up from school each day often reminds me of my days in grammar school. The brick-walled schools that I attended years ago are still in use today (they seemed so much bigger back then), and still providing students with a great environment in which to learn.
But just as I am reminded that every year I am getting older, there are reminders that the country’s thousands of school buildings are aging, too. Many are being replaced with new, state-of-the-art schools, and many more are being retrofitted to make them current with the latest education, technology and energy standards.
And with more frequency than in the past, those familiar brick walls are being upgraded and replaced with new, energy-efficient metal walls and roofs. Take, for instance, the Metal Construction Association’s newest case study on the William Allen High School in Allentown, PA. The school—originally constructed with brick masonry—had outgrown its existing space, so they built a new addition on an adjacent lot. The exterior of the new building is a combination of brick and metal panels, with the majority of wall surfaces being insulated metal panels (IMPs).
The metal complements the brick aesthetically—a trend that we are seeing more and more of—and it helped the new building attain LEED gold certification. Not only are the IMPs energy-efficient, but the added benefit of quick installation (IMPs allowed the building to be enclosed with insulation and the finished panel in one shot) made them an ideal choice for this project.
