Photo courtesy of 4/9 The 3.5 kW of solar electric panels installed on the roof contribute to the $1,905 in annual energy savings the homeowners will experience in this home compared to a home built to the 2009 energy code. Photo courtesy of 5/9 The structural insulated panel (SIP) thermal blanket uses 4.5-inch-thick wall panels (R-20) that sit on a bottom plate sealed against the post-tensioned slab foundation with a flexible foam sill gasket. Photo courtesy of 6/9 The SIP thermal blanket uses 8.25-inch roof panels (R-38) that are lowered into place on the SIP walls. Photo courtesy of 7/9 Because SIPs come to the job site precut to the dimensions that will be needed, on-site construction time is shortened and very little material is wasted. Photo courtesy of 8/9 The joints between the solid SIP panels are sealed, helping to provide an airtight, draft-free structure. Photo courtesy of 9/9 Volunteers helped construct the affordable, high-performance home, which includes solar electric panels to help ensure lower energy bills well into the future.
