Description / Abstract:
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
1) a method to compute the standard calculated energy rating, a
standard energy use that does not depend on occupant behaviour,
actual weather, and other actual (environment or indoor)
conditions,
2) a method to assess the measured energy rating, based on the
delivered and exported energy,
3) a method to improve confidence in the building calculation
model by comparison with actual energy use, and
4) a method to assess the energy effectiveness of possible
improvements.
This International Standard is applicable to a part of a
building (e.g. flat), a whole building, or several buildings.
It is up to national bodies to define under which conditions,
for which purposes, and for which types of buildings the various
ratings apply.
This International Standard handles the energy performance of a
building as a whole. The assessment of the energy performance of
specific technical building systems is handled in the appropriate
part of the EN 15241, EN 15243, and EN 15316 series or the
appropriate International Standards or national standards as listed
in Annex A.
