Renovations, heritage and volumes

For your renovation projects in Solothurn, the federal building register (RegBL) indicates that 3 buildings are listed under heritage protection, requiring early coordination with the municipality for permit applications. The building volume data covers 1517 houses with a median volume of 462 m3 according to the SIA 416 standard, which is essential for scaling your heating and insulation upgrades. Please note that data coverage is partial, as 1514 buildings are recorded under unknown or other standards. Since renovation year data is not available, you should conduct a thorough on-site assessment to accurately plan your specific property improvements.

Tips before you start

  • Solar thermal collectors usually cover much of summer hot water.
  • Combining collectors with a heat pump needs a sizing study.
