Versoix's housing stock in figures
The federal building register lists 1'406 residential buildings with 5'552 dwellings in Versoix. 51% were built before 1980, before serious insulation standards, and 74% are still heated with oil or gas.
With 74% fossil heating and 9.1% electrically heated hot water, many buildings in Versoix will need a new system. Planning ahead avoids deciding under pressure after a breakdown.

Heating and hot water: which energies?
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 44 % | 40 % |
| Heating oil | 30 % | 27.5 % |
| District heating | 3 % | 1 % |
| Heat pump | 17 % | 3.9 % |
| Electricity | 4 % | 9.1 % |
| Wood | 2 % | 1 % |
| Solar thermal | 1 % | 10.3 % |
Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
Type of heating system
- Boiler (unspecified)66.7 %
- Heat pump16.8 %
- Condensing boiler5.3 %
- Standard boiler3.4 %
- Heat exchanger (district)2.8 %
- Direct electric heaters2.3 %
- Central electric heating1.7 %
- Stove0.5 %
A standard non-condensing boiler is usually older and less efficient.
Renovations, heritage and volumes
For your renovation plans in Versoix, the official building register data provides limited insights due to partial coverage. Information regarding heritage protection status and the year of renovation is not currently recorded. Furthermore, building volume data, measured under the SIA 416 standard, lacks specific median values to guide your project scale. Given the absence of these figures, it is essential to contact the municipality directly. Engaging with local authorities early is the best way to obtain the precise technical details required for planning heating or insulation works and ensuring your renovation cost estimates are accurate.

Useful local data
Rules of the canton of Geneva
These rules apply across the whole canton, not only in this town.
Fossil heating rules
- Note : Les exigences s'appliquent également aux nouvelles constructions, qui doivent être entièrement alimentées en chaleur renouvelable.
- Legal basis : Loi sur l'énergie (Le)
- In force since : 1er juin 2020
- Heating replacement : En cas de remplacement d'une installation de production de chaleur (chauffage et/ou eau chaude sanitaire), 100% de la chaleur doit être d'origine renouvelable, à l'exception des cas où des contraintes techniques ou financières empêchent l'atteinte de cet objectif. Dans ces cas, un minimum de 20% d'énergie renouvelable est exigé, complété par des mesures compensatoires (consommation d'énergie, émissions de CO2 ou performances énergétiques globales).
- Renewable share required : 100% (ou 20% avec mesures compensatoires si contraintes techniques/financières)
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.
