When IMPs first emerged as a building product in the 1960s they were predominantly used as an exterior wall assembly. Throughout the last 60 years, the materials and production methods have advanced considerably. According to the Metal Construction Association, “Insulated Metal Panel Roofs are premier building products on the leading edge of innovation.” The far reaching benefits include: high performance, sustainable building envelope, design flexibility, single component, and speed of build. The question isn’t “why an IMP roof” … the question is “why not.”
Join METALCONLive! and MCA TOMORROW as they present, The Advantages of an IMP Roof, by Greg Lusty, Vice President of Sales at All Weather Insulated Panels. Greg will provide a review of insulated metal roof panel systems in terms of their performance characteristics, profiles, and testing/approval requirements; along with the design and installation considerations that will help you be successful. This webinar qualifies for one AIA LU and its FREE!
Metal Architecture at METALCONLive! is kicking off a new series of webinars aimed at showcasing projects that illustrate the beauty, durability, efficiency, and sustainability of metal. The first live session is scheduled for next Wednesday, January 13 at 1:00 EST and will explore Civitas and the role of metal in meeting a zero carbon world by guest speaker and renowned architect, Barry Yoakum. So what is Civitas? According to its creator and owner, Mr. Yoakum explains, “Civitas is poised to become the first certified zero energy/zero carbon single-family home in the Americas. Positioned overlooking the Mississippi River, the project involves its site fully, connecting interior and exterior and private property with community space. It is a case study house that focuses on balancing the challenges of cultural norms, climatic concerns, resiliency, and adaptability.”
Despite the pandemic, construction carried on and the “top lists” of this year’s architectural marvels are rolling in. ConstructConnect‘s criteria for inclusion on their list boiled down to the following items: The building had to have been substantially completed, topped out, or opened within the calendar year and had to have some aspect that makes the building “cool.” What does this mean? In their terms, it can range from the architecture, sustainability elements, unique construction methods, technology, building materials used, cultural impact, or some combination of these elements. This year, “cool” appears equivalent to “sustainability” along with an “eye on the future.”
In this time where face-to-face trade shows, meetings and conventions have come to a screeching halt, perhaps this amazing renovation and expansion of the Miami Beach Convention Center can provide a ray of hope for this temporarily decimated industry sector. Featured in their October issue, Building Design + Construction reported, “The project was built with the future in mind by using steel construction with composite metal decks for raised floors in the case of rising sea levels. The renovation concepts were inspired by modern designs incorporating natural elements of the ocean, beach, and underwater life. Waves, manta rays, and coral reefs were studied as part of the design process. The building envelope is designed with linear forms that create a curvilinear undulation inspired by ocean waves. The facade has hurricane resistant connections meant to withstand even the largest storms. The interior design finishes emulates receding water, sea foam, and patterns relating to various typed of local coral reef. “
As the year begins to wind down, awards and recognitions begin to roll in. Building Design + Construction just announced the winners of their 22nd annual Building Team Awards program, which celebrates excellence in team collaboration and design/construction solutions. Among the 12 winners are one platinum award, five gold awards, three silver awards, two bronze awards, and one honorable mention. While it was not a judged element, it is interesting to see the use of metal in the design and construction of each project.
This year’s sole Platinum honoree goes to LEED Platinum Emory University Student Center, where students were uniquely and intimately involved in the design. Echoing the comments of many of the judges, Anthony Grumbine, AIA, Principal, Harrison Design (and a BD+C “40 Under 40” honoree) saluted Emory and the project team for their “excellent involvement of students,” the high level of sustainable design, and the delicate preservation of Alumni Memorial Union Center.
Despite the postponement of the 2020 Summer Olympics, one project commemorating the history and spirit of the games, the U.S. Olympic & Paralympic Museum, opened on July 30. The museum was built on 1.7 acres of land near Pikes Peak, blocks away from the U.S. Olympic Committee headquarters. DesignandBuildwithMetal.com reports, “Tasked with constructing the museum’s exterior, MG McGrath Inc. sought to create a skin that matched architecture firm Diller, Scofidio + Renfro’s vision of a building structure and overall exterior visual effect that encapsulated the passion, dedication, and endurance of an Olympic athlete.” To accomplish this, Lorin anodized aluminum panels were selected to create the system of custom metal panels to wrap the double-curved geometry of the façade. The metal was also selected for its durability, low cost, malleability, environmentally friendly qualities, and color and finish.
Last week during our METALCONLive! event, we learned from leading authority on metal roofing recover, Charlie Smith, the number one reason to recover a roof with metal is for its longevity. According to Rob Haddock with S-5!, “A metal roof has three to five to six times the longevity of conventional asphalt shingles.”
While metal roofs have made significant gains in recent years, the industry still fights a perception that the value of metal roofing is less than other roofing materials, especially in the residential market. In his recent article in Metal Architecture, Editorial Director Paul Deffenbaugh takes a look on how to quantify the “return-on-investment (ROI)” for metal roofing.
The article cites, “Currently, a metal roof replacing the existing roofing material returned 61.2% percent of the cost within two years. For an asphalt roof replacement, the return is slightly higher (65.9%) but the cost is significantly lower. There is no data available for the return on investment of a metal roof on a commercial project. For commercial real estate investors, building owners, appraisers, municipalities, appraisers, school boards, insurers and others interested in property values, there is nowhere they can turn to identify the intrinsic value of a metal roof.”
Chuck Howard, PE, president of Metal Roofing Consultants, Cary, N.C., and another industry expert says, “One of the problems we have in our industry is that value of the metal roof is not clearly defined while the value of flat roofs and shingle roofs are. It’s going to be X amount of dollars per foot. You tell people, ‘a flat roof will be $6 per square foot and a metal roof will be $12 per square foot,’ and they say they can’t afford metal.” Howard goes on to explain that sometimes the metal roof is designed to work on a structure that will work with any roof and is consequently overdesigned for a metal roof. Once you get a customer past the “cost” conversation, the payoff– the ROI — for metal roofing comes in the maintenance and durability of the product.
To increase awareness of the longevity of metal roofing, Haddock pushed for a survey to document the real service life of a metal roof. Sponsored by the Metal Construction Association and the ZAC Association, the survey analyzed low-slope, unpainted 55 percent Al-Zn coated steel standing seam roofing in a wide range of environments across the U.S. The research concluded that the expected service life of such a roof constructed today can be expected to be in excess of 60 years. That value, the researchers argue, equals the assumed service life of the building, as described by USGBC’s LEED v4 rating program. Haddock suspects if metal roofing were to warrant roofs to the same service life standard, the warranties would likely run to 60 years.
To help customers overcome the cost objections to metal roofs, Howard developed a spreadsheet that compares the anticipated costs of a metal roof to a typical flat roof including anticipated maintenance. His analysis includes initial costs that show metal roofing coming in at about 30 percent higher but at the 20-year mark, the total cost for a metal roof would be 22 percent less than a flat roof. At 40 years, it would be 60 percent less. And at 60 years, it would be 68 percent less. Over the 60 year life span of the building, the 20-year flat roofs need to be replaced three times and have considerably higher maintenance costs.
The durability of a metal roof provides a significantly better return on investment than a typical flat roof over the predictable service life of a building. Durability and maintenance are key elements positively affecting the ROI for metal roofs. Research from Harvard’s Joint Center for Housing Studies (JCHS) suggests that investments in maintenance and making sure the building doesn’t deteriorate over time improves the return on investment.
“A metal roof, if properly installed, requires no maintenance,” says Haddock. When we were doing the study, we got up on roofs that were 30 years old and nobody had ever been up there.”
While the value of a metal roof may not be apparent at the start, it is fair to say the ROI presents itself later based on the longevity and ease of maintenance.
TOP AIA COTE® AWARD HIGHLIGHTS IMPORTANCE OF TEACHING SUSTAINABILITY AT A YOUNG AGE
Each year, the AIA’s Committee on the Environment (COTE®) recognizes 10 projects that integrate design excellence and environmental performance. One winner receives the COTE Top Ten Plus award—an indication of exemplary proven energy performance and post-occupancy results. This year’s “plus” award was given to the Environmental Nature Center and Preschool in Newport Beach, California, for reasons of “Introducing kids to responsible sustainability at a young age and represents a place where people will want to send their children. It does all the right things—water, biophilia, resilience, and strong material choices.” (ARCHITECT Magazine) Through simple and cost-effective design strategies, the center was certified as the first LEED Platinum building in Orange County, California, and has operated at net zero since it opened, serving the community as an educational tool for sustainability.
