Building the city of tomorrow in the face of climate change - Mapuce
Future climate projections predict a resurgence, lengthening and intensification of heat waves in Western Europe. In urban areas, the artificialisation of surfaces generates a particularly marked overheating effect during heat waves, resulting in a deterioration of thermal comfort due to the increase in temperature and the appearance of urban heat islands. In order to anticipate these effects and integrate these issues into urban planning exercises, a guide of recommendations for urban planners and planning agencies has been published as part of an ANR Mapuce research programme, coordinated by the National Meteorological Research Centre, CNRS and Météo-France. The urban planning exercise constitutes, due to the changes brought about by the Grenelle II law, an appropriate framework for integrating energy and climate issues into regional public policies. To facilitate its implementation, Mapuce first aimed to obtain, from digital simulations, quantitative energy-climate data relevant for urban planning, focusing on building-related energy in the residential and tertiary sectors (41% of final energy consumption). The second objective was to propose a methodology, applicable to all cities in France, for integrating such data into legal procedures and urban policies.
