Impetus for sustainable site development
The "Sustainable site development" 2024 colloquium showed how interdisciplinary approaches and innovative labels such as Minergie site and SNBS site are driving sustainable urban development in Switzerland. From clear certification models and co-operative practice to sufficiency as a strategy. Future-orientated sites are created where comfort, ecology, social integration and resilient economic activity interact.
Switzerland is one step ahead with the harmonisation of labels. Minergie-Areal focuses on energy efficiency, comfort and climate-friendly mobility and, with its streamlined certification process, is ideal for smaller, manageable sites. It sets clear specifications, for example for building quality and monitoring. SNBS-Areal is convincing for large, complex sites of 10,000 m² or more and covers social, economic and ecological aspects in equal measure. With 30 tested criteria and a broad sustainability assessment, it also serves as a basis for ESG reporting and special utilisation planning
The example of Kraftwerk1 in Zurich
Kraftwerk1 demonstrates the value of self-organisation, diversity and solidarity in urban areas. Democracy, low-car living, social rental models and flexible spaces ensure sustainability in practice. The cooperative structure combines individual appropriation with neighbourhood cohesion and strong environmental responsibility
Life cycle, costs and sufficiency as levers
Costs are reduced in the long term where product life cycles are extended, recycling is promoted and resources are optimally utilised. Beat Salzmann explains how life cycle management and the circular economy influence financial planning. Sustainable buildings are investments in the future. Sufficiency, as Boris Szélpal explains, means targeted reduction and conscious use of materials and energy. It expands the understanding of sustainability to include the aspect of voluntary renunciation, the development of resilient living spaces and social structures
Sustainable site development is a coordinated process. Standards create clarity, cooperatives live values and sufficiency opens the way to resilient neighbourhoods with a high quality of life and low environmental impact. The future lies in the balance between comfort and indulgence and in the openness to consistently develop new models
