The Pitt Street Passive Apartment project consists of a three-and-one-half-storey residential building meeting the passive house standards requirements to be certified under the passive house plus certification. The Passive house plus certification utilizes the requirement of reusable energy.  In this case, we plan to achieve this certification with the utilization of a Solar Voltaic System.  Similar to Project I, this high-energy performance dwelling is constructed with a slab on grade (partially submerged basement), exterior insulated concrete form walls and a fully insulated flat roof system. The design of the apartment dwelling supersedes the minimum building code requirements for energy efficiency by 2x and above. The use of this standard will reduce the building's required heating demand to less than 15kWh/(m²a), approximately 90% less than a conventional residential home, in turn, reducing energy cost and fossil fuel use.  Attention to detail for construction details, high-performance materials and carefully planned installation methods has amplified energy efficiency, indoor air quality and overall comfort.
