Climate change requires buildings to be adapted to ensure a sufficient level of comfort during increasingly severe heatwave periods. The challenge is to achieve this objective at lower cost and with lower environmental impact, in new construction but also with regard to the existing stock.
After a state-of-the-art phase and feedback on the 2019 heatwave, climate projection data were developed, a list of adaptation measures and samples of typical buildings were created (individual houses , collective housing, tertiary buildings) by considering different periods of construction.
Performance criteria have been defined to evaluate the effectiveness of the different adaptation solutions proposed. These criteria concern the risks of overheating, taking into account the notion of adaptive comfort, but also the environmental performance evaluated by life cycle analysis (including the possible effects of adaptation measures on heating and air conditioning needs). .
The objective is thus to evaluate the adaptation measures by different indicators, for example: degree-hours of discomfort, CO2 balance, LCA indicators concerning health, biodiversity and resources, costs. The results of these evaluations, which depend on the type of building, the climate considered and the behavior of the occupants, are distributed to project owners, technical design offices, administration in charge of regulations, researchers and other organizations concerned with these subjects.
The prospective climate data developed as part of this project are disseminated to users of dynamic thermal simulation tools. The knowledge acquired during this project could help guide public policies aimed at improving the resilience of buildings to heat waves.
