Primary Energy Factor Definition

The fuels in primary energy are all primary fuels a country s different sources of primary energy are aggregated into a quantity called total primary energy supply tpes.

Primary energy factor definition.

There are several internationally recognised definitions for primary and secondary energy. Our findings on the primary energy factors used by a number of european countries are discussed in chapter 3. Primary energy is reported in energy content terms such as gj or kwh. The purpose of the primary energy factors pefs set out in annex iv of the eed is to assist member states to translate final energy savings into primary energy savings in the framework of article 3 energy efficiency targets and art 7 energy efficiency obligation schemes.

Method and sources this section outlines the process used to derive the primary energy factors in sap. It is energy contained in raw fuels and other forms of energy received as input to a system primary energy can be non renewable or renewable. More background on primary energy factors in relation to the energy performance of buildings directive epbd and relevant cen standards is given in chapter 2. Approaches for definition of primary energy differ in eu member states.

Primary energy pe is an energy form found in nature that has not been subjected to any human engineered conversion process. A more detailed description can be found in the sap 2016 consultation paper consp 072. Sap uses primary energy factors to convert the calculated energy requirements of a dwelling into a primary energy demand figure. Primary energy factors on the building practices in european countries.

The role of the primary energy factor pef in determining the energy performance of buildings in this bpie policy brief publication. To reduce eu primary energy consumption in 2020 by 20 in compari son to a given baseline development. The definition in en iso 52000 1 is primary energy is energy that has not been subjected to any conversion or transformation process. Bpie argues that the current approach using the primary energy factors pefs is detrimental to.

Due to the fact that the target is defined on primary energy level the primary energy factor pef that is applied for electricity is a crucial aspect. The use of primary energy factor pef was chosen by european union policy makers as an obligatory part of methodology for comparing the primary energy consumption of products using different energy sources. Bpie proposes using delivered energy as the main building performance indicator to determine and set requirements for its energy performance.
