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.
The Santa Monica-based award-winning green design studio Minarc partnered up with Habitat for Humanity, and a local non-profit firm Restore Neighborhoods LA to design and build affordable, net-zero energy prefabricated homes in the low-income areas of South Los Angeles. Together they built 3 homes, which were all built on vacant lots in the poorest neighborhood of South Los Angeles. The houses all feature Minarc’s innovative, interlocking panel system, which is called mnmMOD. The homes are also equipped with roof top mounted solar panels.
