Methods used

Sustainable new construction work at the University of Groningen realized with various methods.

Geothermal heat pump

Storing heat and cold in the ground is an environmentally friendly and energy-saving alternative for a conventional cooling installation. Significant savings can also be made on the heating front.  

Geothermal heating works as follows. Cold, available in quantity in winter in the form of cold outside air or cold surface water, is stored in the ground. The stored cold can be used in the summer to cool equipment and rooms. In the summer the heat that is released when generating cooling can be stored in the ground and reused in the winter. Residual heat, for example from a heat pump or combined heat and power installation, can also be stored and reused later.

Geothermal heat pumps have been installed at the Zernike Complex and in the University Library.

New teaching facility UMCG

Concrete core activation

Concrete core activation is a heating and/or cooling system that uses the building’s mass, usually applied in utility construction. Water pipes are installed in the middle of the concrete floor. Water that has been heated by use is cooled to 40 degrees Celsius and then pressed into the water pipes under the floors. This results in simple and cheap heating. In reverse, cool air can be transported back.

Concrete core activation is currently being used in the new teaching building of the Faculty of Medical Sciences.

Energy requirements and sustainability of construction materials

For new buildings, the energy requirements and the sustainability of the materials suggested by the architect are tested in advance by external agencies. They are encouraged to choose energy-efficient, sustainable materials. However, it is important that the sustainability investments are also cost-efficient. This is because the government funding that the University uses are primarily intended for teaching and research.
