Policy Context & Overview
Short Answer: Funded partly by the CO2 levy, this unified program supports canton-specific subsidies to lower the heat energy demand of Swiss buildings.
The Swiss Building Program (Das Gebäudeprogramm) is a joint initiative of the Swiss Confederation and the individual Cantons. Buildings account for approximately 40% of Switzerland's energy consumption and a third of its greenhouse gas emissions. Funded partly by the national CO2 levy, the program provides financial incentives to help property owners insulate building envelopes and replace fossil fuel heating (oil and gas) with clean, renewable alternatives.
Subsidy Structure & Cantonal Variations
While the program operates under a national framework, the specific subsidy values, application portals, and requirements are managed by the individual Cantons (based on the Harmonized Subsidy Model - MuKEn):
- Building Envelope Insulation: Grants typically range from 40 to 100 CHF per square meter of insulated roof, facade, or floor area.
- Fossil Fuel Replacement: Replacing oil or gas boilers with heat pumps (air-to-water or geothermal). Subsidies range from 2,000 to 10,000 CHF based on system size.
- Geothermal Geoloop Bonus: Cantons offer additional bonuses to cover the cost of drilling vertical borehole heat exchangers for geothermal heat pumps.
Eligibility Criteria
- Property Type: Residential, commercial, and public buildings in Switzerland.
- Minimum Scope: Facade and roof insulation projects must meet minimum thermal resistance targets (U-value ≤ 0.20 W/m²K).
- GEAK Certificate Gate: Many cantons require homeowners to obtain a GEAK (Cantonal Building Energy Certificate) before deep renovation funding is approved.
Step-by-Step Application Guide
- Conduct GEAK Audit: Hire a certified energy advisor to assess your property and draft a GEAK report.
- Design Renovations: Choose insulation measures or heat pump upgrades that meet cantonal efficiency guidelines.
- Submit Cantonal Application: Apply online via your Canton's specific Gebäudeprogramm portal before starting construction work.
- Execute & Verify: Complete construction using certified contractors.
- Receive Payout: Submit final invoices and your GEAK compliance certificate to claim the subsidy.
Frequently Asked Questions
- Q: Can I apply for a subsidy after starting construction work?
- A: No. In all cantons, the subsidy application must be submitted and approved before any construction work begins. Retroactive applications are rejected.
- Q: What is a GEAK certificate?
- A: The GEAK (Gebäudeenergieausweis der Kantone) is Switzerland's official building energy rating system, classifying properties on a scale from A (highest efficiency) to G (lowest efficiency).
