Although small in size, tw/rl's impact on zero-energy architecture will be tremendous. From morning to evening, the featured umbrella has many performative functions: to shade from the sun, to ventilate cool air, and to collect solar energy. In order to maximize shade, the user rolls the umbrella manually on a track, which inadvertently positions the umbrella's interwoven surface of solar reflectors and collectors at the optimal angle to the sun. Solar heat is reflected into the spindle of the solar chimney to generate air movement and, simultaneously, is absorbed by photovoltaic tiles for later use.
