Airtight structures minimize radiant heat


Masdar Institute’s laboratory buildings are characterized by air-filled cushions that ensure almost no solar gain on the structures and limit the heat re-radiated to the street. A reflective foil-clad inner layer behind the cushions sends light to the pedestrian street below.

Behind the foil is a highly insulating and highly sealed panel to reduce cooling needs, and rooftop solar panels provide renewable energy. Additionally, outdoor shading elements allow natural daylight to stream into the space while keeping window glass blissfully cool to the touch.
