Single-family house (energy saving house 60) | new build
Concept and architectureThe building was erected with compact exterior style and alignment towards southwest. Wide window openings towards southwest and little window areas at the northern side make an optimal use of solar heat gain possible. Outwalls and load-bearing walls made of sand-lime bricks serve (due to their dimensions), as well as the concrete ceilings, as storage medium for thermal energy. As a result the room temperature is well adjusted during the course of the day. Energetic figures far below energy saving regulation were achieved through an integrated energy concept. Effectively the heating energy consumption including hot water generation uses only about 6 liters fuel oil per m² of energy absorption area.
Construction- Multi-skinned strong insulated exterior wall with back ventilation of the cladding, U = 0.22 W/m²K
- Ridge roof with inner rafter insulation and bottom rafter insulation, U = 0.16 W/m²K
- Floor on soil, U = 0.27 W/m²K
- Window, U = 1.1 W/m²K
Building service engineering- Oil-heating value-boiler in ambient air independent usage combined with floor heating
- Bivalent hot water-solar plant with direct storage and heating-support
- Air refreshing facility with heat recovery, without heat registers
