Energetically modernized with “sunglasses”

The “House of Architects” in Stuttgart is a forum for building culture and the headquarters of the Chamber of Architects of Baden-Württemberg. The glazed foyer has just been completely modernized. Some pane edges had become leaky and the glass had become fogged by condensation between the panes. The glazing was also far below current energetic standards. The sun blinds, which were on the inside, required constant maintenance and blocked the view. The complex requirements for the modernization were to lower the heating and cooling costs, improve the lighting, and provide a clear, glare-free view, unobstructed by shading.
