Indoor Air Quality

What are the key components of an indoor air quality audit?

The audits are created to help the trained assessor, and the building manager, design an appropriate monitoring and cleaning plan to make sure your building occupants are within a healthy environment. The assessment will cover a range of appropriate tests and observations, made by the assessor, using the latest diagnosis laser equipment and laboratory tests.

The assessment will delve in to the following key subjects to analyse and identify problem areas in your ventilation system.

Indoor Pollutants
These are various in nature and almost uncountable in terms of what they could be. Especially when considering the idea that airborne fibrous material can depend on the building, what goes on there, and what size the particles are. The most common volatile organic chemicals (VOCs) that are analysed are nitrogen dioxide, carbon monoxide, carbon dioxide, bacteria, fungi, pollen and Ozone. Additionally, as previously stated, any other material fibres that may or may not be unique.

Outdoor Contaminants

For example, this could be caused by traffic fumes, in built up areas, which enter buildings by infiltration through the building materials themselves and through ventilation systems. Other contaminants come from burning fuels, candles and tobacco (these could be generated as indoor pollutants) and emissions from building materials themselves, including furnishings, cleaning products, electronic equipment, toiletries and animals. The list goes on to include people as possible causes for contamination. Far-reaching outsourced contaminants include fumes or particles (from other neighbouring buildings), cooling towers (vapours), factory smoke and pesticides (from farmland). This list is virtually impossible to finish, since the building could have an unusual environmental setting, which may need to be considered. This could call into question several other factors, like landfill infiltration or underground pollutants, such as oils or carcinogenic gas.

Unique to the building
The factors of contribution, described above, may only be necessary to investigate, should the building be at risk of them. There are other contaminants that simply will not be considered because of where the building is or even depending on what time of year it is. Until the Risk Assessor conducts the experiments, that are necessary to predict and confirm the contaminants, there is no way to put in place a comprehensive and practicable monitoring program, that would be correct for the building.
