ISO 16346 pdf download Energy performance of buildings — Assessment of overall energy performance
This International Standard defines the general procedures to assess the energy performance ofbuildings, including technical building systems, and defines the different types of ratings, and thebuilding boundaries.
The purpose ofthis International Standard is to
collate results from other International Standards that calculate energy use for specific servicesalwithin a building.
baccount for energy generated in the building, some of which may be exported for use elsewhere,
present a summary of the overall energy use of the building in tabular form,c
dprovide energy ratings based on primary energy, carbon dioxide emission, or other parametersdefined by a national energy policy, and
9establish general principles for the calculation of primary energy factors and carbon dioxideemission coefficients.
This International Standard defines the energy services to be taken into account for setting energyperformance 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 notdepend 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 energy3) a method to improve confidence in the building calculation model by comparison with actualenergy use,and
4) a method to assess the energy effectiveness of possible improvements.
This nternational Standard is applicable to apart ofa building(eg.flat),awhole building, or severalbuildings.
lt is up to national bodies to define under which conditions, for which purposes, and for which types ofbuildings the various ratings apply.
This International Standard handles the energy performance of a building as a whole. The assessmentof the energy performance of specific technical building systems is handled in the appropriate part otthe EN 15241,EN 15243, and EN 15316 series or the appropriate International Standards or nationalstandards as listed in Annex A.
