Climate Responsive Building Envelops for Museums and Galleries

  1. 1. IAMFA 2013 Climate Responsive Building Envelops for Museums and Galleries Chris Arkins Emrah Baki Ulas STEENSEN VARMING If a building becomes architecture, then it is art. Clearly if a building is not functionally and technically in order, then it isn’t architecture either, it’s just a building.
