Modelling the impact of installation of heat cost allocators in DH in Croatia

Influential factors on the energy consumption can be defined as physical and non-physical, whereby the non-physical include behavioural aspects, individual cost allocation, demographic factors, the daily use schedule of heated space and others. Previous analyses and models have predominantly taken into consideration only physical factors. In this paper, analyses of heat consumption for 6 heating seasons based on the data supplied by the district heating companies was made. Also, the influence of the calculation formula on invoicing to individual consumers with the installed heat cost allocators is analysed. This analyses is based on the measured consumption data from about 3.800 households in 56 buildings in different Croatian cities. Results show the decrease in final energy use of about 28 % in average, and indicating that there is a significant influence of the heat cost allocators.
