Executive Summary

The Swiss Federal Council is financing sound-insulating windows for residential properties around the military airbases of Meiringen, Payerne, and Emmen. Based on updated noise calculations by EMPA, a total of approximately 280 properties need to be renovated: about 70 in Meiringen, 30 in Payerne, and 180 in Emmen. Installations are scheduled to begin in 2027, with the federal government bearing all costs. The necessary appropriation credit was requested from Parliament with the 2026 Army Message.

The adjustment of renovation figures based on updated data analysis signals a reassessment of noise exposure for affected municipalities. For cantons and municipalities around these strategic aviation sites, planning certainty is created: with implementation beginning in 2027, limit value exceedances will for the first time be systematically corrected in accordance with the Noise Protection Ordinance. The federal government's assumption of full costs relieves local budgets and underscores the recognition of infrastructure follow-up costs as a national responsibility.

Detailed Summary

The noise protection initiative is based on scientific calculations by the Swiss Federal Laboratories for Materials Science and Technology (EMPA), which has identified limit value exceedances at inhabited properties. The Department of Defence (VBS) has already financed sound-insulating windows in earlier phases; this tranche addresses properties not yet renovated with current exceedances.

Renovation planning is differentiated by location: Meiringen and Payerne show lower impact with approximately 100 properties combined, while Emmen forms the focus with around 180 objects. For Emmen, the exact number will only be determined through building inspections in the next planning phase – an indication of the complexity of data collection in comprehensive renovation programs. Implementation is expected to begin in 2027, which factors in a delay of at least one year following today's announcement.

Key Statements

  • Approximately 280 residential properties at three military airbases will receive sound-insulating windows to comply with the Noise Protection Ordinance
  • Federal Council bears renovation costs in full; appropriation credit requested in the 2026 Army Message
  • Implementation planned from 2027 onwards; Emmen requires additional data collection before planning begins

Critical Questions

  1. Evidence/Data Quality: What methodological differences between earlier and current EMPA calculations led to the adjustment in the number of properties? Have the new figures been validated?

  2. Data Quality Emmen: Why is the exact number of properties in Emmen (180 as an estimate) only known after building inspections? Does this indicate gaps in data collection?

  3. Cost Responsibility: On what legal or political basis does the federal government bear 100% of renovation costs rather than sharing these with affected municipalities?

  4. Timeline and Risks: What reasons lead to the delay until 2027? Is there a risk of further postponements?

  5. Implementation Capacity: How many windows can be installed per year? Is a multi-year program with corresponding capacity bottlenecks planned?

  6. Limit Value Definition: Which noise limit values of the ordinance are being exceeded, and are there differences between daytime and nighttime values?
