Heat-resilient urban and neighborhood development in large cities – Resident-oriented knowledge generation and implementation in Dresden and Erfurt

Challenges Aims

How does it feel to live with hot outside temperatures in a HeatResilientCity develops and implements innovative, socially strongly compacted residential quarter? In such just and user accepted adaptation measures to reduce the Average temperatures are based on averaging neighborhoods, heat stress is a serious issue for residents, as two almost cloud-free Landsat exposures of summer heat load of people in buildings and open spaces. The 20 June 2000 and 22 July 2006. summer heat waves can significantly reduce people's well- interdisciplinary and transdisciplinary research network

Together with the scientific partners, actors from the How can the quality of life be improved with reasonable effort building industry and urban development form a creative and despite summer heat? What role do the building structure and innovative environment. The two municipalities coordinate the the materials used play? How much energy will be needed in inner-city networking, organize and coordinate the work in the the future - for heating in winter and cooling in summer? What real-life laboratories and support the development and real effect can one expect from façade greening, open implementation of adaptation measures through the watercourses and green areas?
