-The air volume V<sub>n50</sub> within the heated building envelope is the volume that will be used for calculating [[planning:airtight_construction:general_principles:blower_door_test|the n50 air leakage value]]. It is supposed to indicate the //actual// volume of air that will be heated or cooled within the building and should be calculated separately for each room. The calculation should be carried out in accordance with detailed rules given in the [[https://passivehouse.com/downloads/03_building_criteria_en.pdf| Criteria for Buildings]], section 3.2.10 Airtightness of the building envelope.  +The air volume V<sub>n50</sub> within the heated building envelope is the volume that will be used for calculating [[planning:airtight_construction:general_principles:blower_door_test|the n50 air leakage value]].
