Solar-ready metal roofing project wins award
The state-of-the-art Riverview Branch Library in Riverview, Florida, has won first prize for the commercial rooftop category in Academic Technology Approval Scheme (ATAS) International’s 2020 Project of the Year competition.
Standing metal roof panels manufactured by ATAS in .040 aluminum were installed on this new library. The panels, with a seam height of 0.61 m (2 ft) and a panel width of 4.65 m (15.25 ft), were mechanically seamed, followed by the installation of photovoltaic panels. The panel is a double interlocked structural panel that can withstand heavy load requirements.
The contractor, Alpha Roofing and Sheet Metal of Orlando, Florida, installed a total of 4113 m2 (44,276 sf) metal standing seam roof panels, including some tapered panels. Factory tapered panels ensure quality and dimensional accuracy as well as easier installation in the field. The metal roofing was purchased through Beacon Building Products of Orlando, Florida.
Standing seam metal roofing is an ideal choice for solar systems due to its longevity. When installing a crystalline system, which is typically guaranteed for 25 years of power generation, a building owner benefits from a roof substrate that has a longer lifespan than the solar panels.
Standing seam metal panels also provide a natural platform for fixing crystalline systems without roof penetrations, using clamps that attach to the panel seams. In addition, highly reflective roofs with cooler roof temperatures improve the performance of the solar panels.
The 3251.6 m2 (35,000-sf) Riverview Branch Library was designed in the old Florida grandeur style by FleischmanGarcia Architecture of Tampa, Florida. Ken Zuker, senior associate at FleischmanGarcia Architecture, stated: “The county commissioner dictated a pitched roof for this building, as it is a county building with an expected lifespan of 50 to 60 years, and a metal roof was the obvious choice. Because there would be 340 solar panels on the roof, we opted for aluminum as the metal substrate because of its long lifespan.”
