The Belgium HQ of ventilation and solar shading manufacturer Renson has been received a 2009 Good Green Design award from the European Centre for Architecture Art and Design along with the Chicago Museum of Architecture and Design

Designed by architect Jo Crepain and engineers VK Engineering the building is naturally ventilated and uses night cooling to pre-cool the structure to help maintain thermal comfort in the summer.
