A short description of a second generation low-energy house built at Hjortekaer in 1984, with a calculated annual heat demand of 3500 kWh (excluding domestic hot water), is given. The house is superinsulated and very airtight. The roof and walls are insulated with 400 and 300 mm of high quality mineral wool respectively, with infinitesimal thermal bridges, and the floor is a slab-on-grade construction insulated with 200 mm polystyrene. Most of the windows are south facing and fitted with a new type of lightweight external insulating shutter. A few typical construction details are chosen to illustrate airtight construction without cold bridges. Some preliminary results from pressurization tests and infiltration measurements are presented.
