Fact of the Day: Earth Day Edition

By: John Ryan, Metal Construction Association 

It’s Earth Day today, and here is one fact that struck me, courtesy of the American Iron and Steel Institute (AISI):

More steel is recycled annually than paper, plastic, aluminum and glass combined.

I thought that was pretty remarkable. Approximately 90% of metal roofs and insulated metal panels are made out of steel, much of which is recycled content. That’s just one of the many green benefits found in metal roofs and walls.

In honor of St. Patrick’s Day, the Metal Construction Association (MCA) has decided to celebrate our favorite metal green buildings; figuratively and literally. MCA—and its members—embrace the green construction movement, and support sustainable and energy-efficient products. Here is a list of some green projects we hope you will find interesting and inspiring.

The Bullitt Center, Seattle

Billed as the greenest, most energy efficient commercial building in the world, The Bullitt Center is a net zero energy building that is being constructed to meet the goals of the Living Building Challenge. Scheduled to open in 2013, the building features metal panels from Metal Sales Manufacturing Corporation that have a long life span, are 100% recyclable and contain a high percentage of recycled material.

Just to close the loop on our recent glut of posts about solar power and metal roofs, we are pleased to share a Solar Energy Industries Association (SEIA) report released today that states that 2012 was a record year for solar installation, as reported by CNN.

In 2012 more than 3.3 gigawatts of solar power were installed, which is enough to power about 500,000 homes. That is a 76% increase from 2011, and the industry expects another record year for solar power installations in 2013.

“There were 16 million solar panels installed in the U.S. last year – more than 2 panels per second of the work day – and every one of these panels was bolted down by a member of the U.S. workforce,” said Rhone Resch, president and CEO of SEIA. “We’ve brought more new solar online in 2012 than in the three prior years combined.”

See below for some fun facts about the Top 10 Solar States, and visit SEIA for an executive summary of the full report.

Solar Roofs Revisited: Economic Benefits as well as Green Benefits

Metal Roofing and Solar PanelsBy: John Ryan, Metal Construction Association

The connection (pun intended) between metal roofing and solar (photovoltaic) systems has been a common theme for the Metal Construction Association’s The Metal Initiative these past few months. See some of the latest blog entries from February and December. We also recently hosted a webinar for architects on the metal roofing and solar topic. If you missed us, sign up for our next “Metal Roofing: The Perfect Platform for Solar Technologies” webinar.

And our friends at DesignandBuildwithMetal.com have been covering the story, publishing two stories on the topic recently. Ken Buchinger from MBCI recently wrote an article that shared his perspective about why standing seam metal roofs make the perfect platform for photovoltaic (PV) systems because the roofs have a service life that is likely to outlive the PV system, and because the systems can be mounted to metal roofs without penetrating the roof. Bob Zabcik of NCI Group, Inc. also penned an article that confronts common misconceptions about solar roofing.

We’re used to hearing about the well-established green and sustainable benefits of solar roofing, but Bob and Ken both take the stance that there are significant economical benefits in solar roofing, as well. PV systems can be expensive, but over time these systems can generate significant returns on the initial investment. And to protect that investment, metal roofing is the ideal platform for PV systems.

DOD + Metal Retrofit = Energy Efficiency

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.Goodfellow AFB

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.

Explore Metal Roofing’s Many Green Benefits

Sykes Chapel uses metal for roofAlthough metal roofing is now considered a building product of choice among a vast legion of green-minded customers, sometimes we need to be reminded of its many ecological benefits. A recent Metal Construction Association technical bulletin provides a quick but very thorough rundown of metal roofing benefits, including that metal roofing:

• Can virtually eliminate the need to use future raw materials to produce roofing.
• Is unaffected by hot-cold or wet-dry weather cycles that break down other materials.
• Has recycled content ranging from 25% to 95%.
• Is fully recyclable if it is removed, perhaps as part of a building renovation.
• Is low weight compared to other roofing materials, which helps extend the life of buildings, among other benefits.
• Does not pose a health risk.
• Is increasingly regarded for its energy efficiency.

Green Building Pioneer: Use Commonsense Roofing Design

The greenest house in AmericaIn 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.

Green Roofing System
“A roof should act as a shading umbrella,” Pfeiffer said. “R-value means little if the house leaks, the windows are unshaded, or the roof is a dark color.”

“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.”

Top Reasons to Use Insulated Metal Panels

More often than not, architects and designers choose Insulated Metal Panels (IMPs) for a combination of reasons, not the least of which is aesthetics given that they come in a variety of styles, sizes, colors, finishes, and textures and can be installed both horizontally and vertically. Metl-Span’s Tuff Wall® IMPs, for example, provide a stucco-like appearance to the new corporate-headquarter addition to the Hitchiner Manufacturing facility, Milford, NH, a casting supplier to manufacturers in the aerospace gas turbine engine industry. But according to Dennis Mires, PA, of The Architects in Manchester, NH, IMPs also met insurance requirements, stayed within the owner’s budget, and provided a high-tech look for the company.

With that in mind, what are top reasons for choosing IMPs? Industry experts say that the metal panels:

IMP Manufacturing Suppliesare energy-efficient. IMPs have two metal skins, an interior and an exterior, which are bonded to a foam polyisocyanurate insulation core, making them highly energy efficient, said Brian Jaks of Green Span Profiles, Waller, TX, a manufacturer of IMPs. Initially used on cold-storage facilities, the panels have R values as high as 8 per inch, compared to 3.7–4.3 per inch for batt insulation, and range in thickness from 2–6 inches.

have thermal performance. According to Ken Buchinger of Metal Building Components, Inc., who recently spoke at METALCON, IMPs provide continuous insulation and consistent R values across walls, and have concealed fastener systems that prevent thermal bridging between the exterior and interior skins. He further noted that IMPs tend to hold their R value over time and do not have significant thermal drift.

allow for fast installation. IMPs’ one-piece construction makes for faster installation, Buchinger said. Faster installation helps lower construction costs and interim financing costs. Moreover, he said, the steel skins are resistant to abuse and, compared to conventional building envelope materials, are not as affected by adverse weather conditions such as high winds.

are suitable for green building. IMPs were used on the new LEED-gold-certified “Bartholomew Building” addition to William Allen High School in Allentown, PA,   for their simplicity of design. “The [system] just goes together,” said Mitch Miller, associate and director of specifications of USA Architects, Easton, PA. “You’re installing the insulation and the finished panel at the same time.” Furthermore, the metal in a panel’s skin often has a high content of recycled steel or aluminum, and, when IMPs are removed from a wall, they can be recycled or re-used on another project, saving them from the landfill.

offer unsurpassed design flexibility. “People like the panel because it has a flat appearance,” Jaks said. “It doesn’t necessarily have corrugation and architects like that.” He added that IMPs are available in a variety of textures, including smooth, embossed, and heavy embossed. They also come in wide range of colors, and can be customized to match any color palette. IMPs’ design flexibility allows the ability to achieve almost any look and increase curb appeal.

are well suited for roof applications. More than 130,000 sq. ft. of IMPs was used to reroof the eight-building Haughton Middle School complex in Haughton, LA.  According to Lauren Marchive, project architect with Newman Marchive Carlisle, Inc., Shreveport, LA, the local school board chose IMPs for their thermal performance and because the roof system was available in red, which matched the school’s original design. Even more vital was the speed and ease of installation, and that the roof could be installed during the school year on sections of buildings that were not in use.

are code complaint. In his AIA presentation, Insulated Metal Panels (IMPs): High Performance Green Building Products, Randy Wilken of Metal Building Components, Inc., noted that IMPs qualify as continuous insulation, where required by the International Energy Conservation Code and ASHRAE 90.1. They are also available in ASHRAE/California-compliant cool-roof colors, as listed on the Cool Roof Rating Council’s website (www.coolroofs.org).

Choosing between metal construction materials and systems can be complex—each project has a number of factors that need to be considered. But IMPs offer a host of benefits to make them an attractive choice for a wide variety of projects.

School Construction Trending Towards Metal

By: John Ryan, Metal Construction Association

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.

Retrofitted High School
William Allen High School, Allentown, PA

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.

Check out our case study library for additional examples of how schools—new and old—are making use of metal walls and roofs.
