This unique construction method provides on-site quality control, predictability, cost effectiveness, speed, a low carbon footprint and flexibility. In addition each project possesses an individual design and layout that reflects the needs of its future occupants.
Each Facit home incorporates a thermal envelope, where the home's “chassis” (more like a car than a traditional wooden frame) is airtight and stacked with insulation. This ensures that the home conserves energy and minimizes heat loss. “If you want to get geeky that's 0.14 W/m²/K heat-loss co-efficient for floors, walls and roof,” said Bell. In addition each home can be designed to feature a solar thermal system and photovoltaic panels.
Home owners Celia and Diana of Hertfordshire, UK, were the first to successfully have their home built using the on site D-Process. Their modern two story home features natural unfinished materials to blend in with its rural context and large south facing windows which are triple glazed to maximize heat retention in cold weather. Furthermore the entire 200 m² (2,153 ft²) house only requires a heating system with an output of just 4 kW, equivalent to a single radiator.
Facit Homes were also behind the design and construction of Villa Asserbo in Denmark, in partnership with Eentileen architects. This 115 m² (1,250 ft²) home was built from 800 sheets of sustainable plywood and features a series of angles, pitches and covered verandas which take advantage of natural light and the surrounding woodlands views.
