On the existing sites of Fluvius, around the Keerdok and on the site of the Rodekruisplein in Mechelen, a new mixed urban development project is being realized with housing, a hotel, retail, offices, parking facilities,...　

Ingenium was commissioned by Fluvius to investigate the feasibility of a collective very low temperature energy system for heating and cooling of the various buildings (LATENT).In this concept, each individual building has a collective heat pump for heating and a heat exchanger for passive cooling, both connected to the energy system.

This very low temperature energy system acts as a source network for the heat pumps and heat exchangers. As a heat and cold source, several collective BEO fields (borehole energy storage) are connected to this district network, so that the soil is used as seasonal storage of heat. For the thermal ground balance on an annual basis, heat extraction from the Dijle River was studied on the one hand, and sewage thermal energy on the other: a major sewage collector of Aquafin that collects wastewater from a large part of Mechelen's downtown passes through the site and must be reconnected for the project. In a subsequent phase, the concept was worked out in depth technically and answers were also sought to organizational and legal questions.

In addition, Ingenium supports Fluvius in the step-by-step rollout of this energy concept.
