Dr. Julika Weiß


Dr. rer. nat., Environmental Engineer

How can climate protection succeed in the interplay between framework conditions and individual behavior? This is the question that drives Julika Weiß as head of research at the IÖW. After completing her doctorate on the topic of sustainable consumption, she specialized in her current focus: the heating transition.

In numerous projects, Julika Weiß develops recommendations for the energy-efficient refurbishment and climate-neutral heat supply of buildings and neighborhoods. Other core topics include rebound effects, municipal climate protection, the impact of working from home and digitalization. Here, the environmental engineer sheds light on technological, ecological, social, political and economic aspects.
