What is this standard about?
This European standard is part of a series that aims to internationally harmonize the assessment methodology for the energy performance of buildings, called ‘the EPB set of standards’.
This one is the general standard on generation by combustion sub-systems (boilers, biomass) and is also intended for generation for domestic hot water production and/or space heating. These values are input data for calculation of the overall energy used according to BS EN ISO 52000-1 and BS EN 15316-1.
Who is this standard for?
- Users of EPB standards (e.g. architects, engineers, regulators)
- Users of the voluntary common European Union certification scheme for the energy performance of non-residential buildings (EPBD art.11.9)
- Other regional (e.g. Pan European) parties wanting to confirm their assumptions by classifying building energy performance for a dedicated building stock
Why should you use this standard?
For space heating generation by combustion sub-systems (boilers, biomass), including control, it specifies:
- Required inputs
- A calculation method
- Resulting outputs
- A method to take into account the energy performance of heat generation devices based on fuel combustion
It also specifies methods to calculate:
- Thermal losses from the heating and the domestic hot water generation system
- Recoverable thermal losses for space heating from the heating and the domestic hot water generation system
- Auxiliary energy of the heating and domestic hot water generation systems
It specifies the energy performance calculation of water based heat generation sub-systems including control based on combustion of fuels (“boilers”), operating with conventional fossil fuels as well as renewable fuels.
This standard is also applicable to heat generators for heating or for combined service as domestic hot water, ventilation, cooling and heating. Generators for domestic hot water only are taken into account in part M8-8.
NOTE: This standard does not cover sizing or inspection of boilers.
What’s changed since the last update?
This standard supersedes BS EN 15316-3-3:2007, BS EN 15316-4-1:2008 and BS EN 15316-4-7:2008. The main changes are:
a) The typology method was removed
b) The boiler cycling method has been added for existing boilers to get the input parameters for the case specific boiler efficiency method
