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