Abstract

The digitalization of the demand side increased significantly in the last few years. This was mainly due to the impulse of the European Energy Efficiency Directive (EED 2012/2018), binding member states to have all energy meters remotely
readable by January 2027. In collaboration with the Danish industrial partners and the local district heating (DH) operator in Viborg, the innovative use and integration of data from heat cost allocators, DH energy meters, and temperature sensors
helped secure low-temperature operations in existing buildings. It was documented that existing buildings connected to the local DH network can be comfortably heated with a supply and return temperature of 55/30 °C in the DH at 0 °C outdoor temperature without any deep energy renovation in the building or investments, yet secure correct control and operation of the heating systems.
