Bernex's housing stock in figures
The federal building register lists 1'611 residential buildings with 4'686 dwellings in Bernex. 55% were built before 1980, before serious insulation standards, and 63% are still heated with oil or gas.
Only 12.2% of residential buildings in Bernex 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 your renovation projects in Bernex, the federal building registry data shows partial coverage. Although the register lists 1611 buildings, specific details regarding renovation years, heritage protection status, and building volumes based on the SIA 416 standard are not currently recorded or available in our system. Due to this lack of specific RegBL figures, property owners should communicate directly with the local municipal authorities to obtain precise information about their property before starting any major work. Early coordination with the municipality ensures that you address all relevant planning requirements and local building regulations for your renovation project.
