Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
13.2 % of buildings mix housing with shops or offices.
For your renovation plans in Altendorf, federal building registry data provides vital insights for your budget. The median house volume is recorded at 1250 m3 according to the SIA 416 standard, which is essential for scaling heating and insulation requirements. Please be aware that data coverage is partial, as 800 buildings rely on other or unknown standards. Regarding heritage protection, information is missing for most of the housing stock. We strongly recommend contacting the municipal authorities early in your planning process to clarify any building restrictions or permit requirements before proceeding with your renovation project.

Solar thermal collectors capture sunlight to heat a fluid, which then transfers heat to a storage tank. In Switzerland, solar thermal collectors usually cover much of summer hot water, reducing the load on your primary heating system.
This is a great way to improve your energy independence while increasing your property value in Altendorf. To evaluate the realistic cost of this type of installation, use our RenoIndex estimation tool to quickly see the investment required for your home.
Integrating a solar thermal system should be consistent with your existing heating setup. If you already use or are planning a heat pump, note that combining collectors with a heat pump needs a sizing study.
