When infiltration and ventilation of a building are reduced in order to achieve energy savings, indoor air quality might deteriorate. Formaldehyde and other aldehydes, important indoor air contaminants, were studied as a function of building air exchange rates in public buildings and energy-efficient research houses. Sequential gas bubbling systems were used in conjunction with a pneumatic flow control system for field sampling. Samples were collected simultaneously for formaldehyde and total aliphatic aldehydes, and were analyzed in the laboratory using modified chromotropic acid, pararosaniline and MBTH methods. At public buildings, it was found that concentrations of formaldehyde and aldehydes were about the same in indoor and outdoor air due largely to traditionally high ventilation rates in these buildings. However, it is evident that indoor air in general has higher formaldehyde and total aliphatic aldehyde levels than outdoor air. Residential buildings and office trailers, in particular, have formaldehyde and total aliphatic aldehyde concentrations that can exceed the promulgated European indoor formaldehyde standard of 120 μg/m³ (~100 ppB). Since these high air contaminant levels might have adverse health and comfort effects on building occupants, further study is needed to establish ventilation requirements for energy-efficient building designs.
