Frey Architekten on the Photovoltaic Conference in Lyon, France2014.12.02

The German-French agency for renewable energies (DFBEE) organized its PV conference in Lyon in the Chamber of Industry and Commerce on December 2, 2014 on the topic: “What contribution can solar energy make to the implementation of the German and French energy efficiency goals?”

The building sector is responsible for a substantial share of energy consumption in Germany and France. This sector is therefore an important field of action for the implementation of the energy turnaround.


The EU Directive of 2010 provides for an energy consumption of almost zero by the end of 2020 for all new construction and for public buildings by the end of 2018. In order to achieve these objectives, the rapid implementation of large building projects with their own energy production and management from renewable energy sources is required to create the required feasibility.

The crucial factor for a successful system is scientific monitoring, simulation, analysis and monitoring of the data already in the concept phase.

As a sample project, graduate engineer Jürgen Heller from Frey Architekten presented the “Smart Green Tower” in Freiburg. The vision: With smart buildings in a smart power grid through to smart green cities. Intelligent building, as an active part of a smart grid, will form the basis of the smart green city.
