Our topic in TEC21! The current issue highlights the added value of dynamic simulations as a tool for optimising buildings.

The article "Simulations in the service of energy efficiency" and the interview "We are talking about a factor of 10 to even 100" show the current status and potential of dynamic methods with physical simulation models.

The background to the issue is the massive oversizing of heating and cooling generators, which the research study "OptiPower" has demonstrably shown. Dynamic building simulations are the aforementioned approach to reducing this overdimensioning. This method makes it possible to understand buildings holistically and to analyse and optimise them under varying boundary conditions.

This is precisely why our association exists and serves as a network of experts who actively promote and disseminate the method. We are very pleased about this issue of TEC21 and would like to thank Ueli Stüssi for the excellent research and all those who actively contributed: Andreas Witzig, David Akeret, Manuel Frey and Moritz Zwahlen

In the thematic focus

• Simulations in the service of energy efficiency - Ulrich Stüssi
  Although dynamic building simulations can create a wide range of added value, they are still a niche market. This is all the more astonishing in view of current research results and convincing practical examples. We take up the cudgels in favour of this planning method.
• "We are talking about a factor of 10 to even 100" - Ulrich Stüsssi
  The financial and technical benefits of simulations exceed their costs many times over. In an interview with two specialists from Gruner, we find out who exactly benefits from the advantages and why such services are not requested more frequently.
