Winchester/Camberley Homes is partnering with Home Innovation Research Labs on a new construction test home (NCTH) in Silver Spring, MD in the mixed humid climate. The Building America goals for this test home are twofold: 1) to develop and implement optimized framing air sealing, and insulation systems that increase the wall insulation level by 30% and improve air sealing effectiveness with minimized cost increases, and 2) integrate the envelope and space conditioning systems into a high performing home design that can be constructed on a production basis using quality management practices. As a BA test home, this home will be evaluated to detail energy use as well as wall moisture performance.
