Phase I IAQ Site Investigation

Many indoor air quality complaints can be easily resolved without sophisticated sampling. At EE&G we have developed a three-stage approach to resolve indoor air quality issues which results in the most successful and cost-effective completion of IAQ projects. Many indoor air quality complaints can be easily resolved without sophisticated sampling. This is why EE&G remains a Leading Environmental Engineering company in South Florida.

Phase I IAQ Site Investigation

  • Inspection and characterization of the HVAC system
  • Visual inspection of the facility for evidence of microbiological amplification
  • Interviews with affected occupants (employees)
  • Measurement of thermal comfort parameters (temperature, relative humidity)
  • Determination of the amount and distribution of fresh air
  • Evaluation and documentation of operations, which may impact, air quality
  • Determination of pressure differentials and mapping of moisture vapor
  • Identification of moisture content in building materials

Phase II Air and Material Sampling

  • Airborne particulate characterization
  • Surface microbial organisms
  • Dust Mites
  • Total Volatile Organic Compounds (TVOCs)
  • Carbon monoxide
  • Airborne microbial organisms
  • Bioaerosols (skin cell fragments, insect parts, fibers, dust, and aeroallergens)
  • Cockroach extract
  • Radon gas

Phase III Remediation Design

  • Test and Balance of HVAC System
  • Adjustment of HVAC system to provide a higher quality of air
  • Retrofit of HVAC system to allow more fresh air to enter the space
  • Restructure maintenance activities, including training of staff
  • Design HVAC system to allow for improved distribution of air
  • Comprehensive cleaning and decontamination of duct systems and Air Handlers

Indoor air quality (IAQ) is the air quality within and around buildings and structures. IAQ is known to affect the health, comfort, and well-being of building occupants. Poor indoor air quality has been linked to Sick Building Syndrome, reduced productivity and impaired learning in schools.

IAQ can be affected by gases

IAQ can be affected by gases (including carbon monoxideradonvolatile organic compounds), particulatesmicrobial contaminants (moldbacteria), or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. Residential units can further improve indoor air quality by routine cleaning of carpets and area rugs.

Determination of IAQ

Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, a collection of samples on building surfaces, and computer modeling of air flow inside buildings.

IAQ is part of indoor environmental quality (IEQ), which includes IAQ as well as other physical and psychological aspects of life indoors (e.g., lighting, visual quality, acoustics, and thermal comfort).

Indoor air pollution in developing nations is a major health hazard. A major source of indoor air pollution in developing countries is the burning of biomass (e.g. wood, charcoal, dung, or crop residue) for heating and cooking. The resulting exposure to high levels of particulate matter resulted in between 1.5 million and 2 million deaths in 2000.
