Overview of the Report
The document is an explanatory report titled “Prüfung der Agglomerationsprogramme 5. Generation” published by the Swiss Federal Office for Spatial Development (Bundesamt für Raumentwicklung, ARE). It evaluates the fifth generation of agglomeration programmes, a national strategy aimed at coordinating urban development across Switzerland. The report is publicly accessible and was submitted to the database on 16 October 2026.
Scope and Purpose
The study analyses 42 agglomeration programmes that together request CHF 11.2 billion in funding. Its primary purpose is to assess the effectiveness of these programmes and to determine the appropriate federal contribution, which is set between 30 % and 50 % based on measured outcomes and the performance of earlier generations.
Key Financial Data
- Total requested funding: CHF 11.2 billion.
- Federal funding rate: 30 %–50 % of the total, contingent on programme efficiency.
- Funding is allocated to support sustainable housing, infrastructure, and spatial planning initiatives within the identified agglomerations.
Programme Structure
The five‑generation framework builds on previous iterations by introducing stricter performance metrics, enhanced coordination mechanisms, and a stronger focus on sustainability. Each agglomeration programme is required to present measurable targets for housing density, energy efficiency, and transport integration.
Sustainability Highlights
- Emphasis on energy‑efficient construction and retrofitting of existing housing stock.
- Promotion of mixed‑use developments to reduce commuting distances.
- Integration of green spaces and climate‑resilient infrastructure.
- Alignment with Swiss climate targets and European Union sustainability guidelines.
Measured Effectiveness
Effectiveness is evaluated through indicators such as:
- Reduction of per‑capita CO₂ emissions in urban areas.
- Increase in the share of renewable energy in residential buildings.
- Improvement of public transport accessibility.
- Achievement of housing affordability goals.
Implementation Timeline
The report outlines a multi‑year rollout, with regular monitoring cycles. The refresh cycle for the data is set to the fourth quarter of 2026, ensuring that progress is tracked and adjustments can be made promptly.
Stakeholder Involvement
The evaluation process involves federal authorities, cantonal governments, municipal planners, and private sector partners. Collaboration is designed to foster shared responsibility for sustainable urban growth across the 42 agglomerations.
Conclusions and Recommendations
The study concludes that a federal contribution of 30 %–50 % is justified when programmes demonstrate concrete sustainability outcomes. It recommends:
- Continued refinement of performance metrics.
- Greater emphasis on affordable, energy‑efficient housing.
- Enhanced data collection to support evidence‑based decision‑making. These recommendations aim to ensure that the agglomeration programmes effectively contribute to Switzerland’s broader sustainable housing objectives and serve as a model for pan‑European urban development strategies.
