Indoor Air Quality Testing in Office Buildings

IAQ Testing in Commercial Buildings, Offices and Schools

“Sick Building Syndrome” is a term for buildings with health-compromising air conditions which result in generalized discomfort, reduced productivity and employee dissatisfaction at work.  Building-Related Illness from exposures to specific air contaminants such as roof tar applications or other chemicals released into indoor air may also occur. Since 1992, ESMCorp has been NJ’s leader in IAQ assessment services With the risks posed by COVID-19 and its highly infectious variants, Commercial, Government, School, Healthcare and Retail employers seek our technical expertise to ensure that indoor air quality is optimized for safety as businesses return to full occupancy.  


Recent wildfires in Canada have caused smoke and high levels of airborne particles (PM2.5 and PM10) in outdoor air throughout the NJ/Mid-Atlantic Region. ESMCORP Air Quality Experts are assisting our customers with needed HVAC and other adjustments to maintain safe Indoor Air and Continuity of Business.

The most recent May, 2023 CDC guidelines for offices now recommend a target of 5 air changes per hour of a combination of ventilation, dilution, and filtration approaches to reduce risks of COVID spread now that the COVID Public Health Emergency Declaration has expired.  Meeting these guidelines is challenging for various building types.  Let us work with your facilities and HVAC team to determine the best combination for your site.

Common Indoor Air Quality Warning Signs and Parameters


Unusual odors may indicate the presence of air toxins or chemical hazards.

Carbon Dioxide & Fresh Air Supply

Adequate introduction of clean outdoor air is essential for good air quality and reduction of risk from infection in buildings. Insufficient outdoor air increases air quality risks from other factors. When fresh air introduction is optimized, accumulations of other contaminants may be reduced.   

Volatile Organic Compounds, Formaldehyde Carbon Monoxide & Chemical Contaminants

Volatile Organic Compounds are vapors that emit from cleaning supplies, hand sanitizers, building furnishings, or industrial and manufacturing processes.  We utilize the latest technologies for measuring VOC’s, carbon monoxide and formaldehyde in real time using hand-held scientific instruments, or in some cases, we may deploy special sampling and analytical techniques with laboratory analysis. 

Temperature and Humidity

A building’s indoor temperature and humidity affects its indoor air quality and occupancy comfort. Extremely dry conditions can irritate a person’s eyes and upper respiratory system. Alternatively, excessive humidity promotes the growth of mold on in air handlers and on surfaces. Thermostat settings in buildings can also impact humidity, thermal comfort, airborne mold levels, and in some cases, fresh air supply.  ESMCorp considers these factors as part of our air quality assessment services.   


Many Individuals have varying responses to naturally occurring mold spores and water-damage associated mold contamination.  The staff at ESMCorp are highly qualified to determine whether airborne mold levels are within their normal ranges, or if HVAC adjustments or more intensive remediation is necessary.  

Dusts and Allergens

There are many types of dusts and allergens including pollen, animal parts, plant parts, and inorganic materials. Some chemical compounds including metals, isocyanate, aldehyde and other classes cause or exacerbate allergies.
