Thermal performance in the built environment. Determination of air flow rate in building applications by field measuring methods LONG_TITLE Verification of each phase1 Scope In the cooling and heating loads of a building, the air taken in from outside account for a large portion of the entire load; in order to estimate this load, it is necessary to correctly grasp the air flow rate of ventilation and air conditioning systems. This International Standard stipulates the methods for measuring the rate of air flow through the ducts in a steadily operating ventilation and air conditioning system and in the air control
