Single-family house (energy saving house 60) | new build

Concept and architecture
The 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
