Besides energy efficiency, this client was strongly motivated by indoor air quality. All products and finishes were chosen to be zero or low VOC. This house was wrapped in cork, before cladding in local larch. And wall cavities were filled with sheep’s wool insulation. The PV system on the garage is sized for the house to be net zero, and be able to charge an electric car. This house achieved certificates in Indoor Air Quality Plus, Fortified Homes, Energy Star, and National Green Building Standard.
