Improved operation of heating systems in multi-storey buildings to realize low temperatures in district heating networks

This project focuses on developing and demonstrating a new digitalized service package that can significantly improve the operation of heating systems in multi-storey buildings connected to district heating networks. The smart service package will make use of data from existing digital energy meters in the heating system (heat cost allocator meters on all the radiators, DHW systems and energy meters in the central substation in the building) in combination with new room temperature sensors in a number of typical rooms to identify optimized set points in the controls of supply temperatures in space heating systems with radiators and heating power for the domestic hot water system. A constant monitoring of the systems will also allow the continuous commissioning of the heating systems in the buildings that will provide great help in detecting and fixing errors in the systems. This is instrumental to lower the operating temperatures in district heating systems, reduce peak loads in the networks, unlock the possibility to use low temperature waste heat and renewable energy and ensure the required comfort to the end-users in a cost and resource-efficient way
