Indoor Air Quality Monitoring

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide (CO2), carbon monoxide (CO) and volatile organic compounds to particulates, humidity and bacteria such as legionella. CO2 is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying the building. CO2 production is a function of the number, size and activity levels of the people present in the building. Local concentrations can therefore vary dramatically – for example when a meeting room is occupied, or while workers are on lunch or coffee breaks. Excess CO2 levels can lead to tiredness and a lack of concentration and can contribute to the symptoms of Sick Building Syndrome such as headaches, eye, nose and throat irritation, itchy skin and nausea.

Indoor air quality (IAQ)

by Dimtech S.A     based in Keratsini, GREECE

Indoor Air Quality (IAQ) refers to the effects on human health of various factors that are properties or constituents of the air we breathe and generally indoors. Very briefly, we can say that a series of events led to the finding that many chemical or biological substances can be inhaled which can cause various health problems which start as simple disorders but lead to serious illnesses. Of similar importance are several natural parameters of the so-called `interior environment`.

BREEAM Air Quality

by Gradko International Ltd     based in Winchester, UNITED KINGDOM

The sustainability and environmental impact of a new build house is typically assessed using BREEAM. Part of the BREEAM assessment method is determining the air quality inside the house. Gradko can supply a range of products for qualified BREEAM assessors. We try to work with qualified BREEAM assessors to determine and meet their requirements. The products we normally supply are used for monitoring formaldehye and VOC levels in new build properties.

Measurement of methane and non-methane hydrocarbons for environmental air quality.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Model 8900 Methane/Non-Methane Analyzer provides direct measurement of Methane and Non-Methane Hydrocarbons. This instrument is utilized in ambient air monitoring networks around metropolitan areas, fence-line monitoring at industrial plants and hazardous waste sites, and in the production of high purity industrial gases. Methane is a naturally occurring gas generated from the decomposition of biological materials and industrial activity. Since Methane is not considered a pollutant it is the Non-Methane hydrocarbons that are of primary concern.
