Minewater energy for GGD Zuid-Limburg

The Medical Health Service of South Limburg (GGD) and Mijnwater B.V. agreed in 2016 to provide renewable energy to the building that hadto be renovated at Overloon 2 in Heerlen. By the end of 2017 this building will beequipped with heat and cold and renewable electricity, and will be the ninth project connected to the Minewater pipeline network in Heerlen.

Sustainability certification

The existing building of the GGD in Heerlen has not been demolished but completely stripped and then renovated using various durable materials. In the Sustainability Certification of BREEAM (Building Research Establishment Environmental Assessment Method), the integral energy supply of Minewater is particularly good. BREEAM is the tool for integrating and evaluating the sustainability of new buildings, existing buildings, areas and demolition projects. BREEAM is managed and developed by the Dutch Green Building Council and preserves the buildingenvironment.


Minewater supplies sustainable heat and cold for a total of 4,126 m2 of office space. This means that Minewater uses heat and also cold from a range of available sustainable sources. Through an exchange station and underground pipelines, the energy is transported to a network of buildings. The GGD’s building is based on such a network (cluster network A) that had to be expanded for this connection. In addition, for the purpose of generating renewable electricity, Mijnwater placed 110of solar panels on tworoofs of the GGD building, which are used not only by the office building but also by the mining system. Thus, a fully integrated system provides the necessary CO2 savings, less particulate emissions, less overheating of outdoor air in the summer in Heerlen and surrounding areas, and the building is no longer dependent on natural gas.

In April 2017, civilian activities were completed. The last thing is to connect the pipes to the Minewater energysystem. The GGD building is expected to be fullyconnected in the autumn of 2017.
