passive house 2015 This unique project radically changed our trajectory and understanding of buildings and technology. The clients had an understanding of passive technology and worked closely with us at the design phase as well as the build out. The result is amazing and outrageously energy efficient. Passive building comprises a set of design principles used to attain a quantifiable and rigorous level of energy efficiency within a specific quantifiable comfort level. “Maximize your gains, minimize your losses” summarize the approach. To that end, a passive building is designed and built in accordance with these five building-science principles and consumes 70-90% less energy than the standard home. 1)It employs continuous insulation through its entire envelope without any thermal bridging. 2)The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air. 3)It employes high-performance windows (typically triple-paned) and doors 4)It uses some form of balanced heat- and moisture-recovery ventilation and uses a minimal space conditioning system. 5)Solar gain is managed to exploit the sun's energy for heating purposes and to minimize it in cooling seasons. This little "test house" was the experiment where we tested all materials and techniques for the passive envelope. We are currently moving forward on the design for the main house that will accompany this structure on the lot.
