By 2030, we will generate at least 70% of our revenue from sustainable construction projects.
Whenever possible, collaborate with sustainability-oriented investors and ensure sustainability is embedded in project definition and planning with clear objectives. Consider the entire life cycle, including use, management, renovation and dismantling. When choosing between replacement construction and renovation, consistently conduct a life cycle assessment and use environmental product declarations (EPDs, e.g. in accordance with the DIN EN 15804 standard). Overall, the principle remains: reduce, reuse, recycle. This means ensuring structures and components can be reused and dismantled.
Use recyclable building materials where possible and ensure short transport routes. Give preference to renewable building materials, natural stone and technical components suitable for reuse after dismantling or remodelling. Durability, modularity, repairability, and avoiding toxic substances and irreversible compounds in building materials (e.g. in coatings) increase recyclability. Where appropriate, work with existing materials and consider future changes in use. Ensure that material and product data, as well as construction and dismantling plans, remain available long-term.
Consider the built environment as a living space. Promote biodiversity and create meeting zones. Plan native plants and unsealed surfaces that serve both to regulate the microclimate (avoid heat islands, noise protection) and provide space for people and wildlife. Integrate local markets, cultural activities, shared spaces and resources, as well as participation opportunities into your projects. Create inclusive spaces that enable intergenerational living, alternative forms of housing and flexible use.
Implement energy efficiency measures such as thermal insulation, intelligent building management and the use of renewable energy such as solar or wind power to reduce buildings' energy consumption and environmental impact. Plan efficiently, use daylight and air circulation and avoid overheating. Close water cycles and use rainwater or grey water to irrigate green spaces or flush toilets. Use building information modelling (BIM) and, if needed, digital twins to ensure the most efficient planning, construction, management, renovation and demolition process possible.
The Swiss building stock accounts for around 45% of Switzerland's total energy requirements and – depending on the calculation – is responsible for between a quarter and a third of the country's total greenhouse gas emissions. Sustainable buildings and construction methods therefore make a significant contribution to reducing environmental pollution and lead to long-term cost savings. Additional aspects include social mixing, prevention of gentrification, dense construction and careful land use, sustainable mobility, integrated cultural sites, educational facilities, active neighbourhood life, access to fresh food and the promotion of biodiversity.
