Urban Materials for Cool Cities – UMat4CC

Submission summary

The UMat4CC project proposes an integrated interdisciplinary and systemic analysis of climate change adaptation in cities by focusing on the development of deployment strategies for cool materials and urban watering. In particular, it will develop methodological and technological tools for urban cooling in response to more frequent and intense heat-waves.
First, a geographical information system will be developed to assist cities in spatializing their urban cooling strategy. It will help rank urban areas according to their vulnerability to heat-waves, the exposure of their population and their cooling potential thanks to cool materials or urban watering. This work is based on an interdisciplinary collaboration between physicists and social scientists.
Second, experimental studies will be carried out in the laboratory on multilayer samples of three kinds of urban facets: pavements, façades and roofs. These experiments will study the fundamental thermo-climatic performance of cool urban materials as well as the performance of urban watering applied to these structures. Urban watering will also be optimized on the basis of these trials. Approximately ten samples of each type of urban facet will be studied under identical heat-wave conditions in a climate chamber with artificial sunlight in order to identify the dominant properties responsible for their cooling performance.
Based on this work, new material formulations will be proposed taking into account both new cooling objectives as well as existing mechanical (pavements) and thermal (facades and roofs) design goals. These results will be integrated into the geospatial analyses, in particular to assess the cooling potential of cool materials and urban watering.
Knowledge transfer to urban practitioners, decision makers and industry is at the heart of the project, which will draw on the expertise of a scientific and technical stakeholder committee and will disseminate the project's main results during an end-of-project seminar.
