Consider this scenario: three employees on the second floor of a commercial office building in Augusta have been complaining about headaches and sinus irritation for weeks. The building manager checks the HVAC filter, which looks fine, and opens a window for a few hours. The complaints continue. Eventually someone suggests the new carpet installed two months ago might be the problem. It is. The carpet and adhesive are off-gassing formaldehyde and volatile organic compounds at levels well above what most occupants can tolerate.
According to the EPA, Americans spend approximately 90% of their time indoors, and indoor air pollutant concentrations are often two to five times higher than outdoor levels. In office environments, poor indoor air quality (IAQ) is one of the most common and least recognized sources of occupant complaints.
What Is in Your Office Air
Indoor air contains a mix of pollutants from sources both inside and outside the building. In commercial offices, the most common culprits include the following.
Volatile Organic Compounds (VOCs)
VOCs are gases emitted by a wide range of products and materials. In an office setting, sources include new carpet and flooring, paint and adhesives, office furniture (particularly items made with pressed wood or particleboard), cleaning products, printer and copier emissions, dry-erase markers, and personal care products used by occupants.
Common VOCs found in office environments include formaldehyde, benzene, toluene, xylene, and ethylene glycol. Many of these compounds cause irritation of the eyes, nose, and throat at low concentrations. At higher concentrations, some are associated with more serious health effects. The EPA notes that VOC concentrations are consistently higher indoors than outdoors, typically by a factor of two to ten.
Particulate Matter
Particulate matter (PM) refers to tiny particles suspended in the air. PM10 (particles 10 micrometers or smaller) can irritate the respiratory tract. PM2.5 (particles 2.5 micrometers or smaller) can penetrate deep into the lungs and enter the bloodstream. In offices, particulate sources include outdoor air infiltrating the building, printer and copier toner, dust from HVAC systems, construction or renovation activities, and mold spores. Poor filtration allows these particles to circulate continuously.
Carbon Dioxide
Carbon dioxide (CO2) is not a pollutant in the traditional sense, but elevated levels indicate inadequate ventilation. In occupied spaces, CO2 is produced by human respiration. Outdoor concentrations are roughly 420 ppm (parts per million). Well-ventilated offices maintain levels below 800 to 1,000 ppm. When levels rise above 1,000 to 1,200 ppm, occupants commonly report fatigue, difficulty concentrating, and headaches. CO2 is a reliable proxy for overall ventilation quality. The OSHA indoor air quality guidance identifies ventilation inadequacy as one of the primary contributors to sick building complaints.
Mold
Commercial buildings in the CSRA are vulnerable to mold from roof leaks, plumbing failures, HVAC condensate issues, and poor moisture management. Office mold is often hidden: in wall cavities behind leaks, inside HVAC equipment with saturated insulation, under flooring that absorbed water from a slow leak, or above drop ceilings where roof penetrations allow moisture entry. Employees who notice symptoms that improve on weekends or during time away from the building may be experiencing mold-related irritation.
Sick Building Syndrome and When to Suspect It
The EPA defines sick building syndrome as a situation in which building occupants experience acute health or comfort effects that appear to be linked to time spent in the building, but no specific illness or cause can be identified. Symptoms typically resolve after leaving the building and return upon re-entry. Common complaints include headaches, eye and throat irritation, fatigue, dizziness, and skin irritation.
Office environments that warrant IAQ investigation typically show one or more of the following patterns:
- Multiple employees reporting similar symptoms with no clear medical explanation
- Symptoms that correlate with time in specific areas of the building
- Musty odors, visible staining, or known water intrusion history
- Recent renovation, new furniture installation, or HVAC system changes
- A building with older HVAC equipment or an unresolved maintenance history
What Office IAQ Testing Includes
A professional IAQ assessment for a commercial space typically includes air sampling for VOCs and formaldehyde, particulate matter measurement, CO2 and ventilation rate assessment, surface and air sampling for mold and biological contaminants, and a walkthrough to identify visible sources and problem areas. The scope of testing depends on the building, the complaints, and the suspected source.
Testing produces results that point toward specific sources and specific remedies. Without testing, building managers are left guessing, and interventions such as replacing filters, painting over stains, or adding an air purifier may not address the actual problem.
Why Offices in Augusta and the CSRA Benefit From Testing
The CSRA’s hot, humid climate creates conditions that make office IAQ problems more likely than in drier regions. Summer humidity in Augusta regularly exceeds 70%, which strains HVAC moisture removal and provides favorable conditions for mold in any building with a moisture pathway. Seasonal transitions, particularly the shift from summer cooling to fall conditions, are when HVAC systems produce the most condensate and when filters and drain pans are most likely to be overwhelmed.
EnviroPro 360 provides indoor air quality testing for commercial office buildings, medical offices, educational facilities, and other occupied commercial spaces throughout Augusta, Evans, Martinez, Grovetown, North Augusta, Aiken, and surrounding CSRA communities. Testing is based on EPA and industry protocols, and results are delivered in written reports suitable for property management, employer HR documentation, or tenant records.
Schedule an Office IAQ Assessment
If employees in a building in the CSRA are experiencing unexplained symptoms, or if a recent renovation or HVAC change has raised questions about air quality, professional testing provides the data needed to identify the source and document conditions. To schedule an office IAQ assessment in Augusta or the surrounding region, contact EnviroPro 360.
