The Kilkenny Passive Semi Detached project consists of a two-storey residential building meeting the passive house standards requirements to be certified under the passive house classic certification. This high-energy performance dwelling is constructed with a slab on grade, exterior insulated concrete form walls and a fully insulated truss roof system. The design of the semi 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. This project will be claiming the first Certified Passive House Semi-Detached residence in the SD&G Area.
