In accordance with the motto "leading by example", we have included some successful examples of modernisation projects here. The best practice archive helps you to plan and carry out your energy-saving modernisation measures more effectively. In addition to details of measures that have already been carried out, you will find contact details for competent partners such as architects, building owners, building planners, contractors and tradesmen in the area. The archive is still under construction and new examples are being constantly added. Have you yourself carried out an exemplary modernisation? If so, we would be thankful for your contribution.
