Beyond materials

New standards and constraints for carbon neutrality from the European and international level.

The sustainability factor of a building today is an assessment criteria for purchasers, lessees and investors. This is expressed by the growing number of certificates for buildings, which evaluate sustainability according to set criteria. Below are some examples:

  • DGNB seal of quality (German Sustainable Building Council)
    This calls for integral planning plus the setting of sustainability goals and takes ecological and economic factors into consideration.

  • Passive house certificate
    Limits annual heating demand to 15 kW/h per m² of living area, so that a building can be heated exclusively by passive energy sources and needs no active heating system. To this end, the Passive House Institute requires a Uw value of ≤ 0.8 W/(m2K) for windows and glass façades.

  • Minergie standard (Switzerland)
    Assesses sustainability based on set energy indicators for buildings, amongst other things. The Minergie label for windows, for example, is granted when a double casement window achieves the demanding insulation value of Uw=1.0 W/(m2K).

  • LEED (Leadership in Energy and Environmental Design)
    Leadership in Energy and Environmental Design (LEED) is a third-party certification program. It is a nationally accepted organization for design, operation and construction of high-performance green buildings. This ensures the buildings are environmentally compatible, provide a healthy work environment and are profitable.
