Dr. ir. Marjolein van Esch is an assistant professor of Environmental Technology and Design at the Faculty of Architecture and the Built Environment of the Delft University of Technology and academic lead Climate Change Adaptation of the TU Delft Climate Action Program. She specialises in the role of urban design in the urban microclimate on the scale levels of the street and neighbourhood. Focus of her research and teaching are design measures for climate adaptation, the Urban Heat Island (UHI) effect and heat stress as well as the influence of the urban climate on the energy use of buildings. The adoption and application of (scientific) knowledge on these topics in practice is of key importance and therefore Marjolein is closely involved in projects with societal partners (e.g. The Van Leeuwenhoekpark in Delft, the Urban Climate Arboreta in Delft, Almere and Dordrecht) and providing education for practitioners.
