Conthey's housing stock in figures
The federal building register lists 3'186 residential buildings with 5'707 dwellings in Conthey. 59% were built before 1980, before serious insulation standards, and 34% are still heated with oil or gas.
Only 4.4% of residential buildings in Conthey 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.
