The San Francisco based studio, Klopf architecture, in collaboration with mechanical engineering firm Monterey Energy Group has successfully completed a net-zero energy house in Cupertino, California. The renovation of the existing home on the site was aimed towards scoring as high as possible on the “GreenPoint Rated System.” The result is a two-story home that is filled with natural light and is capable of producing as much energy as it requires. The net-zero status of the home was achieved through features such as insulated concrete forms, structural insulated panels, high-performance windows, cementations siding and a rooftop-mounted solar photovoltaic array.
Harold Turner’s home near Concord, New Hampshire measures 3,370 square feet and was built using the ROSE construction method, which was created to build affordable net zero energy and cost effective homes in a wide variety of geographical locations and environments. R stands for “Renewable energy production,” O and S stand for “Owner driven spatial design,” and E is for “Energy efficient construction,” while the entire house is known as ROSE cottage and serves as a prototype and test bed for future homes to be built using this method. The entire home was built for $175 per square foot.
When their children went off to college, Professor Ty Newell and his wife Deb were faced with the so-called empty nesters problem of finding themselves living alone in a house too big for them. Instead of just buying a smaller home, the couple decided to build Equinox House, a net-zero home located in Illinois. The house was designed and constructed by Ty and his son Ben in 2010.
