This European Standard specifies the calculation methodology for the evaluation of the amount of
energy used for indoor lighting inside the building and provides a numeric indicator for lighting energy
requirements used for certification purposes. This European Standard can be used for existing
buildings and for the design of new or renovated buildings. It also provides reference schemes to
base the targets for energy allocated for lighting usage. This European Standard also provides a
methodology for the calculation of instantaneous lighting energy use for the estimation of the total
energy performance of the building. Parasitic powers not included in the luminaire are excluded.
In this European Standard, the buildings are classified in the following categories: offices, education
buildings, hospitals, hotels, restaurants, sports facilities, wholesale and retail services and
manufacturing factories.
In some locations outside lighting may be fed with power from the building. This lighting may be used
for illumination of the façade, open-air car park lighting, security lighting, garden lighting etc. These
lighting systems may consume significant energy and if they are fed from the building, this load will
not be included in the Lighting Energy Numeric Indicator or into the values used for heating and
cooling load estimate. If metering of the lighting load is employed, these loads may be included in the
measured lighting energy.
