Optimizing the link between territories and energy is one of the key factors to a successful transition of energy within our territories. The energy consumption of buildings along with that of the transport sector plays a central role in this matter.
At the level of the Grand Paris Metropolis, the energy consumption of buildings (residential and tertiary/service industry) represents about 90TW/pa (ARENE, 2009). This is 65% of total energy consumption, land transport and industry included (regional average). The low levels of energy consumption of new buildings, combined with a low rate of urban renewal mean that in 2050, present-day buildings will be the greatest consumers of energy (and the greatest sources of greenhouse gas emissions). Elements fundamental to the implementation of wide-scale policies as far as the reduction of energy consumption and greenhouse gas emissions (GES) is concerned are: an understanding of the building stock, as much regarding consumption as an ability to support the surge in renewable energy and energy recovery, an assessment of energy networks and the development of renewable energy.
Against this background the “Local Energy Plan (LEP)” has been developed, an initiative undertaken by the Paris Urbanism Agency on the scale of Paris and the Grand Paris Metropolis in partnership with numerous public and private bodies. This plan aims to supply key territorial players with a “tool box” bringing together data and analytical elements via a cartographic system, which will allow them to construct their territorial energy strategy. It will be one of the cornerstones of the future Metropolitan Climate Air Energy Plan.
