This European Standard describes the method to calculate the energy impact of ventilation systems
(including airing) in buildings to be used for applications such as energy calculations, heat and cooling
load calculation.
Its purpose is to define how to calculate the characteristics (temperature, humidity) of the air entering
the building, and the corresponding energies required for its treatment and the auxiliaries electrical
energy required.
This standard can also be used for air heating and cooling systems when they assure the provision of
ventilation, considering that prEN 15243 will provide the required heating or cooling load and the
corresponding air flows and/or air temperatures.
