The Tran residence showcases a number of cutting edge green design and construction technologies. The home’s super insulated shell is built out of pre-fabricated Polyurethane Structural Insulated Panels (SIPs) and Pella triple pane windows. Designed with passive solar strategies in mind, the majority of the home’s windows face south to soak up with warm winter sun and provide ample natural day lighting. In the summer, these windows are shaded by carefully designed overhangs. This bright, cheery home is comfortable year round and extremely energy efficient.
