ISO 16343 pdf download Energy performance of buildings — Methods for expressing energy performance and for energy certification of buildings
This International Standard sets out ways of expressing the energy performance in an energyperformance certificate of a building (including the technical building systems) and ways of expressingenergy performance requirements. This includes an overall numerical energy performance indicatorand classes against benchmarks.
This International Standard additionally includes numerical indicators at system or component level.
This International Standard defines the different types of rating (such as calculated, measured, design.and tailored rating) and the energy uses to take into account (such as heating, cooling, domestic hotwater, ventilation, and lighting)
This International Standard defines
aoverall indicators to express the energy performance of whole buildings, including heatingventilation, air conditioning, domestic hot water, and lighting systems (this includes differentpossible indicators),
ways to express energyrequirements forthe design ofnewbuildings or renovation ofexisting buildings.b
clprocedures to define reference values, and
d) ways to design a procedure for building energy certification.
Furthermore, it provides a (calculation) link between delivered energy and the energy performanceindicators for buildings. Since a building generally uses more than one fuel (e.g. gas and electricity), thedifferent energy sources are collected per energyware. The overall rating is based on a weighted sum ofdelivered energywares. The weightings can be related to, for instance, primary energy or CO2 emissionsto provide the end result of the calculation of energy performance.
t also provides calculation procedures to assess the energy performance on the basis of measuredenergy use, including ways to convert the measured values to values under standardized conditions(environment,user].
Finally, it defines the system boundaries needed to make a distinction between building energy needstechnical building systems, energy supply systems on site, and distant energy supply systems.
This International Standard can be applied to a group of buildings if they are on the same lot, if they areserviced by the same technical systems, and if no more than one of them has a conditioned area of morethan 1 000 m2.
This International Standard provides different options at different levels. When this Internationa.Standard is used to set up national or regional methods for expressing energy performance and/or forenergy certification of buildings, the choices between the options shall not be made by the individuauser but by authorized national or regional bodies.
