1 Scope This International Standard defines the general procedures to assess the energy performance of buildings, including technical building systems, and defines the different types of ratings, and the building boundaries. The purpose of this International Standard is to
a) collate results from other International 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 a national energy policy, and
e) establish general principles for the calculation of primary energy factors and carbon dioxide emission coefficients.
This International Standard defines the energy services to be taken into account for setting energy performance ratings for planned and existing buildings and provides for
Other BS standards
