The axis "Integrated Design Architecture and Sustainability" (IDEAS) is a joint initiative of both the Interdisciplinary Laboratory of Performance-Integrated Design (LIPID) and Laboratory of Architecture and Sustainable Technologies (LAST) of the School of Architecture, Civil and Environmental Engineering (ENAC) at EPFL. It aims to address an increased integration of the various issues related to sustainable architecture within the framework of the Doctoral program Architecture & Science of the city (EDAR) as well as a desire to strengthen exchanges and synergies between the three institutes of ENAC. Towards this end, it lies on one hand on a new interdisciplinary education offer in the form of seminlasars and workshops, and on the other hand on a networking structure for EPFL PhD students.
