Design for adaptability should start with the occupants needs for comfort and indoor air quality. These are partly influences by the changing environmental forces as wind and sun. Weather predictions and the aggegated voting of users about their thermal comfort, should be the leading parameters to adaptable comfort and the adaptable building. To let the building effectively react on the thermal comfort demands it should react to the path of the sun. This can be done optimally by letting rotate the building, its sun protection or both. The external enclosure can be considered the "third skin" of the human body and its comfort (light, fresh air, optimum temperatures, etc.) is based upon human senses and either provided for by natural means (windows for light, passive solar energy for heat, shade for cooling, etc.) or by more artificial means (solar collectors, photovoltaïc panels etc..). There are some examples of buildings which either have a rotating "third skin" or rotated them selves to optimal follow the sun. These building will be presented and discussed. The focus will be onrotating active roofs. This research was part of the Knowledge Centre Building & Systems (KCBS), in which Eindhoven University of Technology and TNO Environment and Geosciences cooperate.
