Metal Construction in Atlanta: Portman Family Middle School

Portman Family Middle School, Atlanta, GA

Editor’s Note: As we gear up for METALCON International, Oct 1-3 in Atlanta, we’re highlighting some of our favorite Atlanta metal construction projects. We hope to see you next week in Atlanta!

Sports arenas, event centers and skyscrapers generate the most buzz around their construction. Other buildings, such as schools, may not enjoy the limelight, but they’re no less important. In fact, one could argue the design, planning and function of a school building affects the future of more people than any other building type.

As you tour Atlanta during the upcoming METALCON, Oct 1-3, you can’t miss metal’s contributions to the city’s famous buildings. But get off the beaten path a bit, and take note of some of the less known, yet highly influential ones.

Atlanta-based Portman Family Middle School is a prime example of design done well, and metal products contribute to the middle school’s educational and green attributes. A LEED Gold-certified building, construction of the middle school was made possible by a generous $10 million donation by Jan and John Portman.

Designed by architecture firm Shepley Bulfinch, the 75,000 sq.-ft. building was completed in 2009. Some of the “green” features of the design include:

• a garden roof used as an interactive learning space with native plants fed by a rainwater-fed runnel carrying water through the garden to a cistern below
• low-flow faucets, waterless urinals, and dual flush toilets
• daylight sensors, solar hot water, and a high-performance exterior envelope

ALPOLIC aluminum composite panels are central to the high-performance exterior envelope. The metal panels were chosen for their versatility, durability, modern appearance and energy efficiency.

As an energy-efficient green building, the middle school not only saves tens of thousands of dollars annually, it also educates hundreds of children about the importance of sustainable living.

Metal’s use as a green construction material will no doubt be a hot topic at METALCON this year. For a prime example of metal’s green attributes in action, check out Portman Family Middle School, too.

“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.

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.after photo WEB

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.

Is RoofPoint Recognition Worth It?

Pose this question to Robert J. Whitcomb, AIA, RRC, of C. B. Goldsmith and Associates, Inc., who served as designer on the RoofPoint-recognized East Lake High School roof-replacement project in Tarpon Springs, FL, and he will answer with a resounding yes.

“Having a program to evaluate, approve, and certify our roofing work has value if just to show our clients that the design was peer-reviewed and found to be sustainable,” says Whitcomb, who, not surprisingly, plans to incorporate the same sustainable strategies used in this project on other future projects.

Like many metal manufacturers, Whitcomb learned about RoofPoint only recently, upon completing the 216,283-sq. ft. high school roof and exterior-renovation project in spring 2012. After familiarizing himself with RoofPoint’s roof rating system, he applied for and received a Roofpoint certificate of recognition for the project.

“Our first impression of RoofPoint was that it is similar to LEED, but for roofing,” Whitcomb says. “We thought it was great that there was a program now in place to recognize our efforts. The validation came when our application [for this project] was approved, and we received our certificate of recognition.”

Whitcomb says that from the start, the school roof project was focused on sustainability, and that aim influenced all decisions, from material selection to phasing and scheduling. The high school’s new roof features a Drexel DMC 175S 0.040‐in. aluminum standing seam (snap lock) metal roof system with custom flashings and details and solar reflective roof coatings over the existing modified roofs, among other features.

What is RoofPoint? RoofPoint is a voluntary, consensus-based green rating system that helps building owners and designers select nonresidential roof systems based on long-term energy and environmental benefits. It was developed by the Center for Environmental Innovation in Roofing (CEIR), Washington, DC, a not-for-profit organization focused on the development and use of environmentally responsible roofing systems and technologies.

Word of RoofPoint is spreading. According to CEIR’s James Hoff, DBA, vice-president of research, and Jim Kirby, AIA, vice-president of sustainability, more than 1,000 roof-project applications are expected by the end of this year, and that number is expected to grow 10-fold in just 5 years. They stress that RoofPoint is particularly applicable to metal roofing systems and that the program

• is suitable for both low-slope and steep slope roofs, including architectural metal systems.

• provides credit for thermal break clips used with many metal roofing systems.

• recognizes a wide variety of roof surface colors other than just white as an appropriate cool roof surface.

• contains credits that help recognize metal roofing’s unique durability and life cycle features.

• recognizes both recycled content and material reuse, which are both very easy with metal.

According to its website, RoofPoint provides a simple, transparent, and professional measure to ensure that new and replacement roof systems are designed, installed, and maintained in accordance with the best sustainable practices available today.

3 Reasons Why Facebook Chose Perforated Metal Panels

Facebook Data Center, Prineville, OR

By: Jane Martinsons, Metal Construction Association

There are three very good reasons why nearly a quarter of the 65,000 square feet of metal wall panels on Facebook’s new data center in Prineville, OR, are perforated panels. Foremost, the screen metal walls secure the center’s sizable generator yard and help ventilate its diesel-fueled backup generators.

The metal panels, including the perforated metal panels, also are customized by Metal Sales Manufacturing Corporation  to allow the entire structure to meet strict LEED® Gold certification standards. More than half of each perforated panel—52.94%, to be exact—is open area for ventilation.

Last is aesthetics. The metal panels perfectly complement the simple and minimalist design of the neutral-colored center. But don’t let the Facebook data center’s understated façade fool you; inside the center is a powerhouse. The energy-efficient structure houses tens of thousands of Facebook’s servers containing information for its 800 million users. The only hint that the building serves one of the busiest websites in the world is the blue flag with the iconic ‘Facebook’ logo.

To recap, those three reasons are –

1. Superior ventilation
2. LEED® Standards
3. Aesthetics

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.

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.
