The Net Zero Carbon Renovation Europe report—led by Alliance HQE-GBC, Deerns and AIA Environnement— analyses and compares low-carbon renovation practices, methodologies and regulatory frameworks across France, Spain, Italy and the Netherlands, highlighting how national contexts influence carbon performance outcomes.
It also presents the outcome of an unprecedented harmonised life-cycle assessment (LCA) applied to seven generic renovation cases, modelled in Paris, Amsterdam, Madrid and Rome, and assessing :
– Embodied carbon (from materials and construction),
– Operational carbon (from building operations),
– Carbon payback time, as the time required for energy savings to offset renovation-related emissions, depending on national energy mixes and construction material data.
shows that the same building can have dramatically different carbon impacts depending on the country where it is located.
