« We used DistrictLab.H™ to optimize the operation of a heating network with 60 kilometers of piping, distributing 45 gigawatt-hours of energy per year. The network was historically fuelled by gas. The results convinced the stakeholders to switch part of the system to hot water, thereby reducing operating risks, heat loss and maintenance costs. In addition, DistrictLab.H™ enabled us to identify the cause of malfunctions at numerous consumers, and to propose corrective actions. DistrictLab.H™ offers significant advantages in terms of calculating optimum operating temperatures to reduce losses, and analyzing multi-producer systems.They have enabled us to make significant savings in analysis time. We are currently pursuing our mission by studying with DistrictLab.H™ the implementation of high-temperature heat pumps to decarbonize our heat production. »
