Marly's housing stock in figures
The federal building register lists 1'415 residential buildings with 4'650 dwellings in Marly. 44% were built before 1980, before serious insulation standards, and 39% are still heated with oil or gas.
Only 2.3% of residential buildings in Marly 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 Marly, official RegBL data provides vital insights. With 17 buildings under heritage protection, contacting the municipality early is essential to secure necessary permits. As renovation year records are unavailable, focus your planning on the building volume, which shows a median of 919 m3 for 9 homes measured via the SIA 416 standard. Please note that data coverage for volume is partial. Despite this, understanding your home's scale is a critical step in accurately estimating the scope of heating and insulation work required for your upcoming renovation project.
