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)
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: **- Mechanical ventilation systems (mechanical exhaust, mechanical supply or balanced system); **- Passive duct ventilation systems for residential and low-rise non-residential buildings;**- Combustion appliances;**- Windows opening by manual operation;**- 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 smaller 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;**- 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**- Buildings with automatic windows (or openings)**- Buildings with industry process ventilation.**The definition of ventilation and airtightness requirements (as indoor air quality, heating and cooling, safety, fire protectionà) is not covered by this standard.**The following information can be found in other standards and technical reports:**- guidance to estimate pressure drops in ducts (CR 14378:2002)**Table 1 shows the relative position of this standard within the EN EPB package of standards.**
