Confignon's housing stock in figures
The federal building register lists 802 residential buildings with 1'853 dwellings in Confignon. 50% were built before 1980, before serious insulation standards, and 69% are still heated with oil or gas.
Only 10.6% of residential buildings in Confignon report a solar thermal system in the register, so most roofs are still free. Photovoltaics are not recorded there; check the solar cadastre for your roof.

Renovations, heritage and volumes
For homeowners planning renovations in Confignon, please be aware that current data coverage from the official building register is partial. With 802 total buildings recorded, key metrics such as the renovation year, heritage protection status, and building volumes based on the SIA 416 standard are currently unavailable or not measured. Because these official figures are missing, we strongly advise you to contact the municipality directly before starting any major energy efficiency or structural work. Consulting local authorities early will help you clarify specific property requirements and ensure your renovation project proceeds smoothly despite the current data limitations.

Permits
- Competent authority : Office de l'urbanisme
- Solar panels : Soumise à autorisation de construire, mais avec une procédure simplifiée si certaines conditions sont remplies (conformité au droit des zones, intégration paysagère et patrimoniale satisfaisante, puissance totale inférieure à 100 kVA). Procédure simplifiée possible par le biais d'une déclaration préalable, si les installations sont sur des toits en pente conformes ou sur des toits plats non visibles, ou dans certains périmètres d'aménagement (zone 4B, 5, 5A, 5B, 6).
- Heat pump : Les pompes à chaleur air-eau ou air-air nécessitent une autorisation de construire si leur puissance dépasse 10 kW. Si elles sont installées à l'intérieur, elles sont soumises à la LCI (Loi sur les constructions et les installations) et non à la LALPT (Loi sur l'aménagement du territoire et les constructions). Pour les pompes à chaleur de puissance inférieure ou égale à 10 kW, une déclaration préalable est nécessaire, accompagnée d'une attestation de conformité acoustique. Des exigences en matière de bruit sont mentionnées pour les installations extérieures, avec des valeurs limites d'immissions fixées par l'Ordonnance sur la protection contre le bruit (OPB) et des règles spécifiques du règlement d'application de la LCI (rLCI). Un bureau spécialisé en acoustique est souvent requis pour les projets complexes.
