The length of time spent indoors in cold climates make its livable space a critical issue. BVN created four different building types, each having its own features, yet sharing inherent flexibility, and features like double height living spaces between a two-story service area and open floor plans. The double height space adds considerably to the sense of space and enhances family interaction. The house features sliding shutters as well as double glazing to provide a barrier to the cold and innovative uses of steel to minimise material usage and save energy. Hot water circulation system heats the lower level, coupled with radiators on the second level. Auxiliary cooling systems are not needed due to the high degree of natural ventilation achieved through the window configurations. BVN’s scheme provides small high quality spaces that are easy for occupants to personalise and maintain

Materials Consideration

The climate demands a well insulated home with glass areas generally minimised. The concept addresses this by achieving a balance between external views and natural light using minimal glass. Double glazed windows are specified with U=1.3 W/m²/°C plus external manually operated sliding shutters for use during periods of intense cold. The concept incorporating a sloping roof structure to shed snow and achieve U=0.2 W/m²/°C, and effective wall insultation to achieve U=0.1 W/m²/°C

Mechanical Systems
Clever design and choice of materials simplifies and minimises heating requirements. A hot water circulation system provides heating through the floors on the first level while the upper floors have radiators. The heat is powered by a gas fired boiler within the home or with the proposed community scheme, there is an option to consider a shared district heating system. Cooling is not required with adequate cross ventilation through open windows.
