Federal subsidies for energy-efficient building retrofits in Switzerland totaled 516.4 million Swiss francs in 2024, a slight decrease from the 528 million francs disbursed in 2023, the Federal Office of Energy (BFE) said on Tuesday.
Demand for funding remains high despite the modest reduction, the BFE noted. The majority of disbursements supported technical building systems and thermal insulation upgrades. For 2025, committed measures are projected to deliver cumulative energy savings of 12.1 billion kilowatt-hours and reduce carbon emissions by 3.3 million tons over their operational lifetimes.
The highest efficiency gains per franc of subsidy were achieved through heating system replacements and district heating solutions, according to the BFE. New commitments for energy retrofits in 2025 amounted to 522 million francs, with cantons reserving funds upon verified eligibility. Disbursements occur progressively as projects advance.
An additional incentive program, established under the Climate and Innovation Act, supported the replacement of fossil-fuel and electric heating systems as well as broader renovations in 2025. Of the 4.8 billion francs allocated for the program’s first year, 90% was allocated to nearly 4,350 approved projects.
