Following the trend set by the Grenelle II law, the urban planning exercise is an appropriate setting for the integration of energy and climate issues in public policies. However, if it provides a framework for project planning, it does not support its implementation, and is an exercise limited to a given territory. To facilitate this implementation, the MApUCE project aims to integrate in urban policies and most relevant legal documents quantitative data from urban microclimate, climate and energy, in a process applicable to all cities of France. The primary objective of this project is to obtain climate and energy quantitative data from numerical simulations, focusing on building energy consumption in the residential and service sectors, which represents 41% of the final energy consumption. We propose to develop, using national databases, a generic and automated method for generating in France and at the scale of urban blocks, the urban architectural, geographical and sociological parameters necessary for energy simulations. In terms of models, the project will use the urban climate model TEB, which includes a building energy module. We will develop a model of energy consumer behaviour in order to further refine energy consumption calculations within TEB. The resulting climate-energy-behaviour coupled model will be applied to a broad range of French cities, to establish a climate-related energy diagnosis across France for current or future (2050) climates. The second objective of the project is to propose a methodology to integrate quantitative data in legal proceedings and urban policies. We plan to work on all planning documents to identify the potential levers for change and the relevant scales regardless of the territories and engineering in place. We will analyse the legal documents to determine how the existing legal systems integrate or not the energy-climate issues. We will then study the implementation policies and few “best cases” in order to evaluate their performances. Finally, based on urban planning agencies requirements, we will define vectors to pass on quantified energy-climate data to legal urban planning documents. These vectors have to be understandable by urban planners and contain the relevant information. These could be urban climate maps. The relevance of the project is to integrate these vectors in the documents and practices that have the greatest potential. Three experiments are planned in Toulouse, Aix en Provence and La Rochelle to confront the developed tools to actual planning approaches. To meet these challenges, the project is organized around strongly interdisciplinary partners in the following fields: law, urban climate, building energetics, architecture, sociology, geography and meteorology, as well as the national federation of urban planning agencies. In terms of results, the cross-analysis of input urban parameters and urban micro-climate-energy simulated data will be available on-line as standardized maps for each of the studied cities. The urban parameter production tool as well as the models will be available as open-source. Finally, in response to the main goal of the project, a guide providing a method of implementation in different legal and incentive documents will be produced. It will identify the levers that improve the implementation of energy savings and climate management policies by integrating them into planning mechanisms "at the right time, at the right place, with the right tool".
