Calculator for Relative Importance of Losses (RiL)

Using this calculator, the coefficient of Relative Importance of Losses (RiL) is obtained by consumed heat, transferred heat to network and hours in a month. Relative importance of losses represent the energy efficiency of DH company and sum of energy lost in the district heating e.g. thermal loss through pipes, water replenishment, etc. Also calculator take into account the electricity needed to deliver power and heat to the consumers. The lower is relative importance of losses the higher is energy efficiency of the DH company. The main users of tool can be DH operators to have an overview about the energy efficiency of heat distribution processes or heat losses in the grid. The tool can be also used by municipalities and national stakeholders to evaluate the DH companies and write specific regulation acts.
