A panel of leading authorities on indoor air pollution and health within medicine and engineering, gathered at UCSC to perform a critical multidisciplinary scientific review of the current state of knowledge of ventilation rates as they impact occupant health in order to develop priorities for additional research that may be needed to evaluate the effect of ventilation rates on health in multiple types of indoor environments, including but not limited to offices, schools, residences, and day cares.


395 articles were retrieved through an extensive literature search by the Principal Investigators. Papers that did not contain data on health and ventilation rates were eliminated. This resulted in a set of 72 papers for further review.


Each paper was randomly assigned and reviewed by two scientists, one with expertise in health and one with expertise in ventilation. When reviewing the paper, information on different aspects of the study was collected including design, methods, data analysis, measurements of airflow rates and effects on health, possible bias, etc., its results and main conclusions.


Reviewed papers were then classified as:

relevant and conclusive

providing sufficient information on ventilation, health effects, data processing, and reporting;

relevant but non-informative

lacking essential information concerning ventilation or health effects; relevant but inconclusive with incomplete data processing or reporting;


not conclusive but suggestive of an association between ventilation and health,


not dealing with the scope, lacking data on health or ventilation or describing case studies.
