GB According to Robin Spence, daylight is essential for the physical and mental well being of the person. Homes must therefore be as transparent as possible.
Light constructions have specific demands for the energy house keeping of a building.
A lightly constructed building heats up quickly due to its low mass which requires extra measures to control the inner climate. Robin Spence developed the 'variable skin house'. The glass enclosure of his home forms, so to speak, a second skin, which regulates the ventilation and inner climate by a computer-controlled lamella system. The transparent enclosure is constructed from an insulated glass outer layer on steel profiles, containing a layer of insulated lamellas, whose position reacts on the climate changes inside and outside the home. The excess of hot air is drawn out and ventilated via floor grates to a heat-exchange in the basement.
