Indoor Air Quality Monitoring and Control

Indoor Air Quality

The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...

Indoor air quality.

Complaints in modern buildings have been attributed to inadequate ventilation for the last 20 years. Few data exist to support this claim. In fact, few studies have actually looked at ventilation and complaints at the same time. These missing studies indicate a failure of three groups of professionals, physicians and health scientists, architects and engineers, and scientists knowledgeable in e...

Indoor Air Quality and Asthma

Numerous contaminants in indoor air and their potential to cause or exacerbate asthma continue to be a subject of public health concern. Many agents are causally associated with or can exacerbate asthma, particularly in children. For formaldehyde, an established respiratory irritant based on numerous studies, the evidence for an association with asthma is still considered only limited or sugges...

Indoor Air Quality Measurement

A qualitative assessment of indoors air quality is presented, by the use of an electronic nose consisting of a gas sensor array, a data acquisition system and a pattern recognition system. The gas sensors are sensitive to gases polluting the indoors air but they are sensitive to indoors temperature and humidity as well. The data acquisition system overtakes the sensors specific response and out...
