Real estate ratings

Developers, project managers and investors want answers to the following questions:

  • Does the project meet the requirements of the 2000 Watt Society?
  • Have the recommendations issued by the SIA with respect to sustainable architecture (112/1) been implemented?
  • Does the project take account of the Energy Efficiency Path Guideline 2040 issued by the SIA?

The examination of the project qualities is used as a basis for specifying possible optimisations and drafting a corresponding measures catalogue.

A qualitative assessment based on the criteria of sustainable architecture issued by the SIA (Recommendation 112/1) can be carried out. Special quantitative criteria of sustainable architecture can be introduced to account for the Energy Efficiency Path Guideline 2040 issued by the SIA.

A statement on the compatibility of a property or a site with the criteria established by the 2000 Watt Society is issued after carrying out the corresponding examination. We would be delighted to help you on the right path.
