SR EN 15242:2007

Ventilation for buildings - Calculation methods for the determination of air flow rates in buildings including infiltration

This European Standard describes the method to calculate the ventilation air flow rates for buildings to be used for applications such as energy calculations, heat and cooling load calculation, summer comfort and indoor air quality evaluation. The ventilation and air tightness requirements (as IAQ, heating and cooling, safety, fire protection…) are not part of the standard. For these different applications, the same iterative method is used but the input parameter should be selected according to the field of application. For specific applications a direct calculation is also defined in this standard. A simplified approach is also allowed at national level following prescribed rules of implementation. The method is meant to be applied to: - Mechanically ventilated building (mechanical exhaust, mechanical supply or balanced system). - Passive ducts. - Hybrid system switching between mechanical and natural modes. - Windows opening by manual operation for airing or summer comfort issues. Automatic windows (or openings) are not directly considered here. Industry process ventilati
