JTC 06 (CIE-ISO): Energy Performance of Lighting in Buildings

To develop an ISO/CIE standard that specifies the calculation methodology for the evaluation of the amount of energy used by lighting systems in buildings. The standard - shall provide a numeric indicator for lighting energy requirements used for certification purposes; - can be used for existing buildings and of new or renovated buildings; - provides reference values as a basis for the targets for energy allocated for lighting usage, keeping in mind lighting design requirements; - provides a methodology for the calculation of instantaneous lighting energy use for the estimation of the total energy performance of the building.
