Renovations, heritage and volumes
For your renovation projects in St. Gallen, the RegBL data provides essential guidance. With 122 protected heritage buildings out of 147 known, contacting the municipality early is vital for securing building permits. Data regarding house volume is partial, covering only 3 buildings measured under the SIA 416 standard with a median of 805 m3; this metric helps scale your insulation or heating works. Please note that the renovation year is not recorded for any of the 8987 buildings listed in this register, meaning this specific information is currently unavailable for your strategic planning.

Analysis of heat source and network
Before any installation, first check whether your area can connect to a priority district heating network. In the canton of St. Gallen, municipal energy planning often defines priority areas for thermal networks.
If your building is located in one of these areas, connection is generally preferred over an individual heat pump.
A preliminary analysis by a qualified heating engineer is essential to validate the technical feasibility of your specific project and ensure optimal compatibility with your home's current distribution system.
Sizing according to local conditions
The local design outdoor temperature sets the heat pump's capacity. In St. Gallen, winter weather conditions require careful attention to ensure stable system performance.
Correct sizing prevents short cycles that wear out the compressor prematurely, while ensuring optimal thermal comfort on the coldest days.
It is recommended to entrust this power study to an expert who will consider both the actual heating needs of your building and the specific features of the St. Gallen climate during technical planning.
Managing noise pollution
Outdoor air-water heat pumps must meet noise limits towards neighbours. In the canton of St. Gallen, regulations require minimizing noise impacts on adjacent plots.
During installation, it is therefore crucial to choose a strategic location, away from rest areas, and to use anti-vibration mounts to reduce structural noise transmission.
Careful planning that integrates noise protection measures not only helps to comply with the law but also maintains good long-term relationships with your immediate neighbours.
Get a reliable budget estimate
A successful energy renovation project requires rigorous financial planning. Costs vary significantly depending on the chosen heat pump technology, the complexity of the hydraulic installation, and any insulation work required for your home.
