Lectures organized within the axis Integrated Design, Architecture and Sustainability (IDEAS) are given by external speakers, both from the academic sphere and from the private sector. Their contributions illustrate in a concrete manner the state of research in the sustainable development of the built environment. Some conferences are directly included in the IDEAS Teaching Unit UE K, whereas other IDEAS conferences, organized in a more autonomous way, are open to a broader audience (students, PhD candidates and staff from ENAC, STI and IC schools, but also any person interested in the addressed theme).
