Nashville-based Xelica LLC fabricated and installed operable windows, clerestory windows and exterior doors for the project. “ allow wind to flow through the windows and then out the clerestory windows on the north side, so you get natural cooling,” Ginn says. “And that’s why you’ll see the lower façade is set back from the upper façade to further facilitate that passive solar design.” “The way the roof is designed, it allows the winter sun to penetrate deep into the space, it blocks the summer sun and shades the glass,” he says. Porches on the east and west sides provide shade during the morning and afternoon. Long overhangs with porches tucked in underneath them prevent the hot, western sun from penetrating deep into the building, causing heat gain, Ginn says. The long roof runs east-west and faces south. Ginn says there are numerous nuanced, bioclimatic responses in the design to promote efficient energy use. Passive solar building design contributes to efficient energy use. “Really what it’s about, it’s about making it comfortable for the inhabitants with the least amount of power possible,” he says. The roof was specified in a light color to avoid the heat island effect, Ginn says. The chains direct water into an underground cistern covered by a wood platform, where it is stored to water plants and trees on the property. fabricated and installed steel components to support stainless steel chains in place of downspouts.

Nashville, Tenn.-based Don Kennedy Roofing Co. “We created the slope that you need for the gutters by extending the roof at the middle, and so the roof is shorter at the ends and longer in the middle to facilitate natural drainage,” Ginn says. The roof’s narrow edge directs water off it. “But the one thing that happens on it that’s interesting is that if you look on the south edge, all the water drains to one point on the roof,” Ginn says. Shed-style roofs are common on agricultural buildings in the hilly, central Tennessee woodlands. It is a simple, sloped, shed-style roof, Ginn says. “The roof’s vented, but other than that you’re not going to get any benefit from ,” Ginn says. “You’ll see that steps up, it bumps up where the heated and cooled spaces are there’s an edge around it.” Cost was also considered. “One reason was to keep the roof edge narrow and slim,” he says. Ginn says the roof is articulated to incorporate rigid foam insulation over interior spaces and omit insulation at two porches on the east and west sides and numerous overhangs. Steven Ginn, principal at Omaha, Neb.-based Steven Ginn Architects LLC, designed the project. The 2016 Metal Architecture Design Awards judging panel selected Bellswoods, a private residence in Franklin, Tenn., to receive the metal roofing award for its strong articulation, highlevel detail and aesthetics.
