Green cooling and heating: ENGIE Deutschland makes the Life Science Campus in Göttingen Fit for the Future

Cologne - Modern real estate space for scientific and technological progress: EBR's new Herbert-Quandt-Strasse innovation quarter in the Grone Süd district of Göttingen will in future bring together various companies with a high level of innovative power. In the first stage of development, EBR Immobilien Invest GmbH is currently building a "flagship" laboratory together with a logistics area and an office complex for the amedes Group, which operates throughout Europe. An elementary component of the future-oriented location for EBR was a sustainable and secure energy supply. In order to fully meet the laboratory building's high requirements for cooling and at the same time cover both the heating and cooling needs of the offices and the heating needs of the logistics areas, EBR relies on the expertise of ENGIE Germany. The specialists for technology, energy and service are responsible for the planning, construction, operation and maintenance of a central heating and cooling system, including the network and house transfer stations. In addition, the team of experts has developed a new supply concept for the competence center that has never been seen before in this form in the surrounding area. Borzou Rafie Elizei, Managing Director at EBR, explains:

"Our goal for the heating and especially for the cooling supply was to find an ecological, future-proof and economical solution. Together with ENGIE Deutschland, we are pleased to realize the amedes Competence Center as the first building ensemble of this kind in Göttingen that is heated and cooled entirely with renewable energies. Together with the amedes Group, we thus represent a showcase example for all companies in the region."

All-round carefree package along the entire value chain for EBR

The all-around green energy supply succeeds for the ENGIE Deutschland team thanks to a novel, highly complex combination of geothermal energy, brine-to-water heat pumps, air-to-water heat pumps and air-cooled chillers. Particularly sophisticated: The SPECTRUM Water from ENGIE Refrigeration, a sister company of ENGIE Deutschland, is used in combination with geothermal energy as a reversibly operated brine-to-water heat pump, thus supporting the balanced operation of the probe field. In the process, 54 geothermal probes achieve a share of coverage for more than three quarters of the building complex's cooling and heating. The drilling for geothermal use has already been completed; geoENERGIE Konzept, another sister company of ENGIE Deutschland, was responsible for planning the geothermal solution. A special feature of the project is that the SPECTRUM Water heat pump with the geothermal probe field as a heat source is not classically used to supply heat, but as a cooling solution - an approach that is unparalleled anywhere in Germany. In addition, photovoltaic systems installed on the building roofs by Solarimo, also part of the ENGIE family, ensure the efficient supply of green electricity to the competence center. Karina Bloche, Sales Manager Real Estate Solutions at ENGIE Deutschland, sums up: "In this project, the focus is clearly on sustainability and future security. With the help of our sister companies, we at ENGIE Deutschland guarantee both along the entire value chain - including maximum efficiency and the best supply security in an all-round carefree package for EBR." The cooling and heating supply for the competence center will begin in 2024, and the supply contract with ENGIE Deutschland will run for 20 years. The KfW standard Effizienzhaus 40 Erneuerbare Energien (EH40 EE for short) implemented by EBR and the DNGB certification additionally underline the sustainability and energy efficiency of the project.

With the completely green cooling and heating supply Life-Science-Campus in Göttingen, Germany, ENGIE Germany demonstrates the enormous potential of renewable energy sources.
