Resumen: Adaptive façades have emerged strongly in extreme climate countries, as their behaviour contributes to
optimize the energy efficiency of buildings and the well-being of the occupants. Its development in temperate
climates could contribute to the achievement of European environmental objectives for 2020 and 2050.
These will only be obtained if occupants accept and know how to use buildings, hence the need for in-use
assessments of buildings, especially of the most innovative ones. In the literature review, very few postoccupational evaluations or assessments of Adaptive Façades have been found, even less in temperate
climates, where the façade must adapt to varied conditions at a short time scale. This article shows the Case
Study of an office building, the Media-TIC, located in Barcelona (Spain), which has a Mediterranean Climate
with mild winters and warm summers. Media-TIC has two different Adaptive Facades facing southeast and
southwest, and the innovative technology consists on inflatable sheets and cushions made of ETFE
(Ethylene Tetrafluor Ethylene). The study was conducted with a small sample of occupants distributed in
different floors and orientations of the building. The behaviour of the Adaptive Façades, the occupants¿
acceptance in respect to the innovative system and the possibilities for its improvement were analysed.
