Standard Indoor Air Quality Testing

Healthy Environments standard indoor air quality investigations involve inspection, performing air testing for contaminants of concern and measurements of physical factors affecting IAQ. The indoor air quality parameters that are monitored continuously in real – time over a minimum period of 24 – hours are the following:

• Carbon Dioxide (CO2) (Parameter used to assess ventilation effectiveness)

• Carbon Monoxide (CO), Nitrogen Dioxide (NO2)

•Total Volatile Organic Compounds (TVOCs) (Gas monitor with PID, VOCs not identified)

• Suspended Particulates PM2.5 and PM10 (Particulate matter with particle size fraction less than or equal to 2.5-microns and 10-microns respectively)

• Airborne Particle Counts at 0.5-micron and 5.0-micron

• Dry Bulb Air Temperature and Relative Humidity

• Airflow measurements

• Micro- organisms (Airborne mould (fungi), bacteria and other organisms are sampled for a maximum period of 8- hours and then samples are submitted to an accredited laboratory for analysis.

Healthy Environments may also investigate other indoor air quality parameters as required depending on likely and or identified problems and potential air pollutants. The following inspection, measurements and testing may be undertaken where required:

• In depth inspection of the mechanical ventilation and air-conditioning systems

• Radiant Heat (Solar load assessments and effects on space temperature control)

• Oxygen Levels

• Volatile Organic Compounds (VOCs identified)

• (Thermal desorption GC – MS analysis of collected air samples)

• Man-made mineral fibres

• Asbestos (background or reassurance air sampling)

• Air quality testing for indoor environments NABERS ratings specified methodologies

• Microbes, surface testing in office environments and amenities, and within HVAC systems

• Background Noise and Vibration

• Nuisance odours (identification and source tracing)

• Air testing in the outdoor air intake of a ventilation system and or elsewhere in HVAC plant

Indoor Air Quality Overview

Large numbers of people work in an office environment, and the air quality in these environments is important to health and comfort of office occupants. There is often no single factor that determines the quality of indoor air in an office space. The IAQ in an office is a complexity of factors that influence the link to human health and comfort effects. Dissatisfaction with aspects of the indoor environment will be expressed at some time by some occupants of most buildings. Levels of complaints will vary from moderate to severe. Many will at least initially, be simply matters of unsatisfactory temperature control and/or air movement (drafts), lighting or intrusive noise. In some cases, the causes of complaints from occupants and negative impact on their health are less easily determined. The term ‘sick building syndrome’ is a term that has been applied when the symptoms are reported by a significant number of occupants of a building when no recognisable specific ailment can be identified; and when the symptoms are relieved within a comparatively short time of leaving the premises.

The symptoms usually reported by occupants are usually headaches, mucous membrane irritation, coughing, wheezing, runny nose, sore eyes, rashes, nausea and dizziness, lethargy, mental fatigue, itching and other unspecified hypersensitivity reactions.
