DIN EN 16798-7:2017-11

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.
