A facade of translucent plastic pillows can be pumped up to alter lighting and temperature inside this domed greenhouse, located at the Aarhus botanical gardens, by C. F. Møller.
The architects worked with membrane facade specialist formTL to create the ETFE plastic facade of the new Tropical House to provide an energy-efficient envelope with a quilted texture around the 18-metre-high structure.
The light and heat conditions within the building can be adapted by increasing or decreasing the air pressure inside the pillows, which then changes the translucence of the facade.
The domed shape and the building's orientation in relation to the points of the compass have been chosen because this precise format gives the smallest surface area coupled with the largest volume, as well as the best possible sunlight incidence in winter, and the least possible in summer," said the architects.
