The purpose of the standard is to:a) collate results from other standards that calculate energy use for specific services within a building; b) account for energy generated in the building, some of which may be exported for use elsewhere;c) present a summary of the overall energy use of the building in tabular form;d) provide energy ratings based on primary energy, carbon dioxide emission or other parameters defined by national energy policy;e) establish general principles for the calculation of primary energy factors and carbon emission coefficients.This standard defines the energy services to be taken into account for setting energy performance ratings fo
