Renovations, heritage and volumes

For homeowners planning renovations in Thalwil, official building register data provides crucial insights. With a median building volume of 800 m3 measured according to SIA 416 standards, owners can better estimate the scope of heating or insulation upgrades. Note that this volume data is only partially covered, representing 13 out of 1050 houses. We strongly recommend contacting the municipality early in your planning process to discuss your specific property requirements. By addressing these structural details before you begin, you ensure that your renovation budget is accurate and that your project aligns perfectly with local building standards.

Tips before you start

  • Solar thermal collectors usually cover much of summer hot water.
  • Combining collectors with a heat pump needs a sizing study.
  • Several cantons subsidise collectors per m² or per installation.
