Calculator for Primary Energy Factor (PEF)

Primary energy factor (PEF) is energy indicator used for quantifying the primary energy use of a plant. It is calculated by using the methodology described in the European Standard EN 15316-4-5. Using this calculator the coefficient of Primary Energy Factor (PEF) is obtained by consumed heat, fuel input to the Heating Plant (HP) and Combined Heat and Power (CHP), electricity production of the cogeneration plants, fuel and its primary resource factor.
