The use of heat pumps in existing multi-family buildings represents an important underexploited potential to help decarbonize the building sector in terms of the heat requirements of urban areas on a large scale. However, challenges may arise which could either turn out to be obstacles or a complete “no-go” for heat pump projects. Legal, technical, administrative, financial and awareness considerations are reviewed here in a Swiss context.
