In collaboration with RIA we changed and refurbished a former factory in ShunYi district into the most energy saving school building in Asia. The whole building was reinforced to the highest standards of earthquake proofing. All outside surfaces are insulated with 30 cm XPS and triple glazed high quality windows fixed in the insulation layer. The ventilation system which continuously provides oxygen rich fresh and filtered air is equipped with a heat exchanger that prevents energy loss from all the used air that is blown out. Therefore the energy requirements are downsized by more than 67%. Compared with other refurbishment costs for similar volumes, we spend only 14% more. Finally the whole interior is made for children, using non-toxic and only natural materials while using modern and ancient Chinese and international design elements. The separately housed gym and canteen have the same features as the main teaching building.
