DIN EN 15193:2008-03

This standard specifies the calculation methodology for the evaluation of the amount of energy used for lighting in the building and provides the numeric indicator for lighting energy requirements used for certification purposes. This 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 standard also provides a methodology for the calculation of dynamic lighting energy use for the estimation of the total energy performance of the building.
