Lynn Crescent Passive House, Orkney
Download
as PDF The project transformed a disused former boiler house and biomass store into new residential home for Orkney Housing Association. The existing single storey building was utilitarian in appearance, set within a residential area. The boiler house comprised masonry walls and concrete tiled pitched roof, while the biomass store's walls were of thick reinforced concrete. The design philosophy aimed to:1. Preserve as much of the existing fabric as possible.2. Transform the building to have a domestic appearance.3. Achieve a low energy solution to minimise the residents fuel bills.4. Achieve Passivhaus Certification.The Lynn Crescent Passive House is the most northerly Certified Passivhaus in the United Kingdom, and the smallest inhabited Passivhaus in the Northern Hemisphere.
