A new technology is emerging from European initiatives which will bring about revolutionary changes in the building industry. A major use of recently developed transparent insulation materials is in the cladding of buildings [1]. The various high technology materials have excellent insulating qualities, while energy gains from solar radiation are also collected. Thus using transparent insulation becomes the most thermally efficient and cost effective construction method known today and can exceed the energy efficiency of conventional passive solar architecture by a wide margin. For the first time it will be possible to build a house which is completely solar heated.
