A new Mondas IoT reference project is currently under construction in Bielefeld: 398 new housing units are being built according to the German energy standards KfW40+ and KfW50 in Grünheide. They will all be supplied with heat generated by four cascaded electric heat pumps via a cold local heating network. Upon completion, 29 PV systems with a total of 680 kWp mounted on the roofs of the multi-family dwellings will supply the tenants with electricity and power their heat pumps. Any remaining demand will be covered by certified green electricity.
We are very pleased about this project in particular, as investors as well as operators, planners and project designers are realizing a visionary lighthouse project for a post-fossil heat supply, which used to be considered unprofitable. However, in light of the ongoing energy and gas crisis, it looks to be very promising, as the Grünheide energy district will ultimately be heated using practically 100% renewable energy. It was pre-emptively decided not to install a gas connection.
Commissioned by Grünheide Energie GmbH, we at Mondas are working with our long-term partner enerquinn GmbH on a data monitoring concept for the energy district. The data monitoring system will record and analyze the production data of the heat pumps and the photovoltaic systems, the battery and heat storage devices as well as the consumption data at the distribution points. The IoT connection makes the financial operation management of the systems particularly easy.
The first construction phase of the residential district has been completed, the first tenants have moved in. The installation of the heating network started in August 2022. At the time of writing, the energy control center was still under construction.
