IAAC develops endesa solar pavilion for barcelona's 2012 smart city expo

designed by the institute for advanced architecture of catalonia (IAAC), the ‘endesa pavilion’ is a highly efficient shelter built to meet very specific energetic and comfort needs. essentially a wooden box, modules on the exterior walls fold out at different distances to create triangular protruding awnings whose exact angle and length are precisely calculated by the position of the sun, the need for shade, and the spatial requirements of the interior.

each section contains photovoltaic cells on top, which block out the sun over the window located underneath or on the downward-facing side. built by the IAAC as part of the 2012 smart city expo in barcelona, the inside of the forms create pockets for people or storage, effectively increasing the livable area on the same size footprint.

a simple pine-wood frame system supports panels of oriented strand board (OSB) which make up the floors and ceiling planes. each component, based on particular algorithms and angles, was digitally fabricated using CNC machines and was assembled in one month with a great amount of precision. all the design issues were solved on the computer, so that each piece could be created afterwards and simply assembled on site.
