SOLAR HOUSES: THE NEXT GENERATION

摘要

In 2002 a broadly supported (a.o. building developers, Dutch WWF) quality mark ‘Solarhouse’ was introduced in the Netherlands, having an overall reduction of energy performance of 25% below standard building regulations with a balanced package including solar techniques, offering an excellent indoor climate and choosing environmentally sound building materials. First experience from both building and market practice were gathered and analysed. With this a further reduction of the energy performance to a level of 50% below common new built practise is possible with common available insulation and installations. Solar techniques are a proven necessity in this. Over cost compared to standard building practise will decrease rapidly according to marketing learning curves which also hold for these proven techniques. Energy performance of new built high quality houses can thus be more than halved at a small fraction of total building cost.
