Process of supplying or removing air by natural or mechanical means to or from a space. Note- Such air is not required to have been conditioned. [Source: EN 15603 Energy performance of buildings - Overall energy use and definition of energy ratings]
Heat recovered from exhaust air to reduce the ventilation heat transfer. [Source: International ISO Standard 13790- Energy performance of buildings — Calculation of energy use for space heating and cooling (2008).]
Heat flow rate due to air entering an enclosed space, either by infiltration or ventilation, divided by the difference between the internal air temperature and the supply air temperature. [Source: International ISO Standard 13790- Energy performance of buildings — Calculation of energy use for space heating and cooling (2008).]
