- The building occupants, numbers, their locations, movements, tasks and symptoms
- The building’s air conditioning and ventilation systems
- Likely contaminants and how people could be exposed.
The indoor air quality investigation will then involve the following:
- A walkthrough inspection to gather information on any related issues, inspect possible problem areas and consult with building occupants
- Review of any documentation available on the reported issues
- Consultation with the person managing the maintenance and control of the air conditioning, heating and ventilation systems (HVAC)
- Air quality testing and assessment by taking measurements where appropriate and comparing with national and international recommended levels
- Forming an opinion on the likely causes to be tested by implementation of corrective actions
- Carrying out further inspection and consultation to see whether the problem has resolved.
Maintaining good indoor air quality should be regarded a high priority in air conditioned office environments. High standards of hygiene need to be employed: filtration systems should be upgraded, regularly serviced and well-maintained.
