Meta-National Database of Buildings in France. Integration of heat-related indicators of French administrative areas.

Abstract

International audienceThe innovation pathways for zero-carbon buildings by 2030 along with counterbalanced climate change impact are major transition challenges of the urban systems. The Urban Heat Island (UHI) effect, the most documented expression of climate change, reinforces the need for immediate action and puts under pressure local authorities. Moving the individual building to the building cluster or district level, involving simultaneous modification of local planning, can increase the current low rate of transition and reduce overall costs. However, the scarce availability of transparent and easily accessible data on building or city performance, which is necessary to cultivate the market for renovations and provide higher level energy efficiency design policies, is a major challenge to achieving the transition. To this end, we present an enhanced version of the French database on buildings with environmental and risk assessment indicators. The latest release includes the description of almost 27 million buildings across the country and the national energy efficiency label. The new proposed version is enhanced with various characteristics of the urban environment following the discretization scheme of administrative boundaries. The four new proposed indicators include UHI Intensity (UHIi), potential mitigation capacity (ΔUHIi), relative mitigation cost (€UHIi) and heat-stress-related vulnerability (HSi), for each administrative boundary of the entire country. The developed data source can help stakeholders for more targeted policy actions and provides high-resolution data for sustainability research studies in the field of urban building energy modeling (UBEM)
