There are two conventions for defining primary energy factors.
a) Total primary energy factor: The conversion factors represent all the energy overheads of delivery to the point of use (e.g. production outside the building system boundary, transport, extraction). In this case, the primary energy conversion factor always exceeds unity.
b) Non-renewable primary energy factor: The conversion factors represent the energy overheads of delivery to the point of use but exclude the renewable energy component of primary energy, which may lead to a primary energy conversion factor less than unity for renewable energy sources.
National annexes giving tables of values representing local conditions for electricity generation and fuel supply may be added to this International Standard. Such tables shall give values for primary energy factors or non-renewable primary energy factors, depending on which are to be used at national level.
Any national annex that defines primary energy factors and non-renewable primary energy factors shall state which of the above overheads have been included (e.g. energy to build the transformation and transportation system). If the coefficients for fuels are given by energy unit, they shall be based on gross calorific values. In the national annex, it shall also be clearly stated which type of factor or coefficient defined in 6.2 is used.
The CO2 emission coefficients shall include all CO2 emissions associated with the primary energy used by the building, as defined in 6.4. It shall be defined at national level whether the CO2 emission coefficients also include the equivalent emissions of other greenhouse gas emissions, e.g. methane.
Any national annex that defines CO2 emission coefficients shall state which of the additional overheads mentioned in 6.2 have been included. If the coefficients for fuels are given by energy unit, they shall be based on gross calorific values. This annex shall also state which type of coefficient defined in 6.2 is used.ISO 16346 pdf free download.
