Phoenix personnel have many years of experience with developing effective solutions to address IAQ concerns in office, school, hospital and residential environments. Typically, a site specific protocol is developed in consultation with site representatives based on the symptoms and concerns of the building occupants, as well as, the findings of a preliminary review of the work environment. As other factors may contribute to occupants’ perceptions, evaluations may include parameters such as lighting and psycho-social aspects. Investigations may range in duration from single day surveys through to comprehensive long term evaluations.

Examples of IAQ Investigations include:

• Comprehensive/Targeted Evaluations, which may incorporate:
  • Walkthrough of building
  • Review of HVAC System
  • Indoor Environment Questionnaire
  • Thermal comfort monitoring (re: ASHRAE 55-2010)
  • Monitoring of carbon dioxide levels and other comfort parameters over extended time periods.
  • Sampling for site specific contaminants (e.g., formaldehyde, volatile organic compounds, airborne environmental fungi (mould), bacteria and allergens, etc.,) 
• Comfort Survey - temperature, relative humidity, carbon dioxide, carbon monoxide and suspended particulate.
• Vehicle Exhaust Surveys (e.g, service garages, underground parking, loading docks and other entrainment issues)
• Odour investigation:
  • Evaluation of odourous and unknown compounds using multiple (or odour specific) sampling methodology
  • Identification of potential sources based on laboratory and literature data
• Monitoring in health care facilities during construction and renovation projects (per CSA Z317.13)
• LEED (Leadership in Energy and Environmental Design) IAQ testing
• Lighting Surveys
• Office Ergonomics
