Tonight we had the pleasure of hosting Philippe Rahm as part of the IaaC Spring Lecture Series with a lecture entitled Thermodynamic Cities. Mr Rahm discussed themes regarding thermodynamics applied to architectural design, on all scales, through a series of works that have been developed in his Studio Philippe Rahm Architectes. Philippe Rahm is architect, principal in the office of Philippe Rahm architectes, based in Paris, France.
