CEN - EN 16798-7

Energy performance of buildings - Ventilation for buildings - Part 7: Calculation methods for the determination of air flow rates in buildings including infiltration (Modules M5- 5)

active, Most Current
Organization: CEN
Publication Date: 1 June 2017
Status: active
Page Count: 64
ICS Code (Ventilation and air-conditioning systems): 91.140.30
ICS Code (Thermal insulation of buildings): 91.120.10
scope:

This European Standard describes the methods to calculate the ventilation air flow rates for buildings to be used for energy calculations evaluation, heating and cooling loads.

This European Standard applies to buildings with one or more of the following characteristics:

- mechanical ventilation systems (mechanical exhaust, mechanical supply or balanced system);

- passive duct ventilation systems for residential and low-rise non-residential buildings;

- combustion appliances;

- window openings (manual or automatic operation); and

- kitchens where cooking is for immediate use (including restaurants).

This European Standard is applicable to hybrid systems combining mechanical and passive duct ventilation systems in residential and low-rise non-residential buildings.

This European Standard applies to buildings with a building height of less than 100 m and rooms where vertical air temperature difference is smaller than 15 K.

The results provided by the standard are:

- the air flow rates entering or leaving a ventilation zone; and

- the air flow rates required to be distributed by the mechanical ventilation system, if present.

This European Standard is not applicable to:

- buildings with kitchens where cooking is not for immediate use; and

- buildings with industry process ventilation.

The definition of ventilation and airtightness requirements (as indoor air quality, heating and cooling, safety, fire protection, etc.) is not covered by this document. The definition of window opening scenarios is not covered by this document.

Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prENISO 52000-1.

NOTE 1 In prENISO/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 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might 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.
