Promising areas for shallow geothermal energy (Breda formation)

This map layer contains calculated clusters based on the grid level heat demand map. Based on this map and the lower limit of 1,000 GJ/ha/year, a selection of areas has been created that have sufficient heat density for a collective solution. A buffer of 50 meters has been created around these clusters to involve neighboring buildings and addresses that have contributed to the high heat demand density in the cluster. For the remaining clusters, it was first checked whether they meet the lower limit of 500 GJ/year for collective solutions. The remaining clusters were then buffered by 300 meters to identify which clusters could be strung as beads to form a larger network. The heat demand of these large clusters was then calculated. For the effective use of a shallow geothermal system, a lower limit of heat demand is required. In this map layer, this lower limit is set at 50,000 GJ/year. Clusters whose heat demand was lower are therefore excluded. To determine the underground heat supply under the cluster, further work was done from the 'laced clusters'. A buffer of 700 meters has been added to these clusters to reach a total of 1,000 meters from the initial clusters. A heat supply density was calculated from the OGT potential maps of Breda and Brussels in the soil under the cluster. This density is multiplied by the surface area of ​​the cluster to calculate the total heat supply. This calculated heat supply and the calculated heat demand of the cluster make a partial sum with the degree of coverage as the answer.
