The Brussels Métro Nord project consists in the extension of the current line 3 to the north of the region, with the construction of a new section linking the North station in Schaerbeek to the Bordet station in Evere.

The aim of this intervention is to better connect the North and South districts of Brussels with its city center. The line has a total extension of 4.5 km and includes 3.8 km of tunnel and 7 stations.

GEOEG has analyzed the feasibility of thermal activation of this tunnel line and its stations in collaboration with the partner Amberg Engineering. The analysis performed by GEOEG for the BMN consisted in assessing the feasibility and estimating the potential associated with the thermal activation of the considered infrastructure.

Multiple thermal activation scenarios for tunnel segments and/or stations were considered to provide a solution that together with complementary vertical geothermal heat exchangers operating underneath the stations can supply heating and cooling to real estate development projects in the vicinity of the metro line.
