Obligations
What this law requires
Apply new exemption criteria for building extensions: exemptions now apply to extensions with surface less than 150 m² AND surélévations (raised structures) with surface less than 150 m² or less than 30% of existing building reference surface
Calculate outdoor amenity space (Sagrément_ext) for collective housing as cumulative surface of balconies, loggias, and terraces in panel form, explicitly excluding roof terraces, ground-level terraces, garden-level terraces, and external access corridors
Calculate average ceiling height (HSPmoy) for residential buildings as weighted average of ceiling heights in residential spaces, weighted by reference surface area of those spaces
Apply new ceiling height modulation coefficient (MbHSP) to Bbio_max calculations for residential buildings in energy performance assessments
Apply new ceiling height modulation coefficient (McHSP) to Cep_nr_max, Cep_max, and Icénergie_max calculations in energy performance standards
