1 Scope
This European Standard applies to the design, energy performance of buildings and
implementation of ventilation, air conditioning and room conditioning systems for non-residential buildings subject to human occupancy, excluding applications
like industrial processes. It focuses on the definitions of the various parameters
that are relevant for such systems.
The guidance for design given in this European Standard and accompanying CEN/TR 16798‑4 are mainly applicable to mechanical supply and/or exhaust ventilation systems. Natural ventilation systems or natural parts of hybrid ventilation systems are not covered by this European Standard. Reference is made to the Technical Report
for informative guidance on the design of such systems.
Applications for residential ventilation are not dealt with in this European Standard.
Performance of ventilation systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
The classification uses different categories. For some values, examples are given
and, for requirements, typical ranges with default values are presented. The default
values given in this European Standard are not normative as such, and should be used
where no other values are specified. Classification should always be appropriate to
the type of building and its intended use, and the basis of the classification should
be explained if the examples given in the European Standard are not to be used.
NOTE 1 Different standards may express the categories for the same parameters in a different way, and also the category symbols may be different.
Table 1 shows the relative position of this European Standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000‑1.
NOTE 2 In CEN ISO/TR 52000‑2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 3 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
