Overview

Assessment of indoor environmental quality parameters including CO₂, CO, temperature, relative humidity, airborne particulates, and volatile organic compounds (VOCs). The survey identifies potential sick building syndrome causes and evaluates whether indoor environments meet acceptable standards for occupant health and comfort.

Methodology

  • Deployment of calibrated IAQ monitor(s) in representative work areas
  • Continuous or spot measurements of CO₂, CO, temperature, humidity, PM2.5/PM10, and VOCs
  • Assessment of ventilation adequacy (air changes per hour)
  • Identification of potential pollutant sources (printers, cleaning agents, HVAC systems)

What You Receive

  • IAQ survey report with measured values per parameter per area
  • Compliance status against ASHRAE 62.1 and SANS guidelines
  • Identification of areas of concern and pollutant sources
  • Recommendations for ventilation improvements and source control
Applicable Legislation:
Environmental Regulations for Workplaces, 1987; ASHRAE Standard 62.1; OHS Act 85 of 1993 Section 8.

Frequently Asked Questions

What is sick building syndrome?
Sick building syndrome refers to symptoms experienced by building occupants — headaches, fatigue, difficulty concentrating, respiratory irritation — that appear linked to time spent in the building but cannot be traced to a specific illness. Poor IAQ is often the cause.
What CO₂ level is acceptable indoors?
ASHRAE recommends indoor CO₂ levels remain below 1,000 ppm. Levels above this typically indicate inadequate ventilation and can cause drowsiness and reduced productivity.
