The so-called +EQ-Net research project developed an energy-plus concept, which will be applied in the area of a demolished row of buildings in Geretsried. The energy concept focuses on ensuring the compliance of energy production with economic and ecological criteria. It also takes seasonal fluctuations into account. Various technologies, such as heat pumps with ground collectors, PV plants, combined heat and power plants, energy storage tanks for heat, cold and electricity will be implemented; in combination with a low-temperature distribution grid and a strong focus on energy efficiency the ample use of these technologies will enable the highest possible level of covering the quarter's electricity requirements.

To keep the share of auxiliary energy as low as possible variable ventilation and heat distribution concepts will be used. The construction of the grid-neutral energy-plus city center („Neue Mitte“) started in summer 2017 and will be completed by 2019.

Additionally to the construction works, the Dresden University of Technology and the Munich University of Applied Sciences are developing a monitoring system to measure the energy consumption patterns of the grid-neutral quarter and its residents. Based on the results, an online tool will be developed to provide insights into operational diagnosis and building optimisation. This tool will enable residents to track their own energy consumption and thus help to raise awareness for a conscious use of energy.
