Advanced Ventilation for Better Health

In this paper the need for change of the present practice of building ventilation is discussed. Results on the importance of ventilation for the health of building occupants are presented to justify the need for change of the focus from room ventilation to ventilation for occupants. The present ventilation design based on ventilation rate has to be complimented with ventilation design based on ventilation air distribution. The performance of advanced ventilation methods providing optimal room air distribution is compared with the present mixing ventilation. The importance of proper design of advanced ventilation and its implementation and operation in practice is highlighted. The need for updating the present standards and considering new standards responding to the developed advanced ventilation methods is concluded.
