A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting 11 GRANT AGREEMENT Nº: NMP2-SE Main issue of existing low emissivity windows: low E coating is either on the outer (max. solar gain, desirable in winter) or the inner side (min. solar gain, desirable in summer) reversible window Breakthrough: to develop a reversible window, so that users can rotate the sash from winter to summer position and vice versa to change the position of low E coating to select the right configuration. Reversible Window

A2PB A2PBEER – Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting 12 GRANT AGREEMENT Nº: NMP2-SE The innovative window concept is based on the idea of reversing sash in vertical or horizontal positions through the central axis. Prototype dimensions 900x1400mm Wooden profiles thickness of 90mm. Prototype DUE TO POSSIBLE PATENT APPLICATION NO TECHNICAL DETAILS AND DRAWINGS CAN BE SHARED
