Abstract: Guidelines for health-based ventilation in Europe are proposed. They take the premise in control of exposures to air pollutants indoors having both indoor and outdoor origin. Exposures are controlled through a double sequential approach, in which source control is the primary strategy while ventilation is the secondary strategy only after all options for source control have been fully implemented. The World Health Organization (WHO) air quality (AQ) guidelines are used to set the exposure limits. A decision diagram is created to guide through the process of source control and to aid the choice of the ventilation rate for a specific building. Ventilation rate is called health-based, when the WHO AQ guidelines have been met both regarding the pollutants in the air used for ventilation and in the indoor air. If the WHO AQ guidelines are met through source control, then the health-based ventilation rate is equal to the base ventilation rate. This is the rate required to handle primarily human bioeffluents. Based on the literature review of epidemiological studies and other considerations, the base ventilation rate has been set at 4 L/s per person. The health-based ventilation rate cannot in any case be lower than the base ventilation rate. If WHO AQ guidelines cannot be met through source control, then the health-based ventilation rate is a multiple of the base rate, high enough to satisfy the WHO AQ guidelines for a specific building. Health-based ventilation guidelines do not define or promote a specific system to provide ventilation. They only advise on design, operation and maintenance of such systems so that the air supplied can always comply with the WHO AQ guidelines. They advise additionally on the separation of health-based ventilation rate for air quality control from the air used to achieve thermal requirements (heating/cooling), and on the use of volume flow per person as the main metric for ventilation. Implementation of the health-based ventilation guidelines is estimated to halve the loss of healthy life years in Europe from indoor exposure to poor air quality from 2 to 1.1 million without significant impact on energy. Harmonized regulation of product labelling and ventilation is needed to implement and get benefit from the guidelines for health-based ventilation. Additionally indoor air quality requirements must be integrated across different legislative acts including the Ambient Air Directive and the Energy Performance Building Directive. These actions will result in advancement in knowledge and technological innovation, and will secure the basic human rights to breathe clean air.
