Indoor Air Quality (IAQ) Testing/Sampling in High-Rise & Large Commercial Buildings

If you need indoor air quality (IAQ) testing/sampling in high-rise & large commercial buildings assistance discussed in this information page, call us at 973-366-4660 or email us at info@atlenv.com for details and a free estimate.

Headquarters located in the New York City (NYC) Metropolitan area since 1978.  We have provided Indoor Air Quality to high-rise building owners and tenants since 1984 in Manhattan and the other boroughs of New York City (NYC), New York (NY).  Our offices in Atlanta, Chicago and Dallas, Los Angeles and Boston have further added to our knowledge and experience in the unique problems of high-rise and large commercial buildings, as well as the problem in large and densely populated communities.

Our experience includes Post-9/11 Building Air Quality in the areas surrounding Ground Zero in New York City (NYC).  This included testing/sampling for asbestos, lead, arsenic, mercury, concrete, dust, PCB’s, VOC’s, mold bacteria, and many other items.

We have developed a distinctive approach to evaluating individual tenant spaces and entire high-rise buildings for air quality, including molds and chemicals.  Sick Building Syndrome and Building-Related Disease are more likely in large commercial spaces because of the complexity of the HVAC systems, a variety of tenants, space constraints, and the surrounding area.  As buildings age, the potential for isolated problems increases while the possibility of building-wide problems decreases.


  • LOCATION:  Heavy commercial or industrial area with carbon monoxide, diesel exhaust, dust, smokestack emissions, cooling towers, and noise.
  • AIR INTAKE LOCATIONS:  Location of intake on ground level adjacent to loading docks below ground intakes or on roofs where exhaust and intakes are adjacent.
  • VERMIN:  Rats, mice, birds, and pets that can spread germs and disease.
  • BUILDING AGE:  Over time, buildings and building systems deteriorate, become inoperable, or accumulate debris.
  • VARIED OCCUPANCY:  Combining offices, computer equipment, printers, health care facilities, daycare, restaurants, schools, warehouses, factories, and studios all in the same building each with different environmental needs results in air quality differences for numerous tenants.
  • MOLD:  Problems due to leaking pipes, roof leaks, flooding, condensation, and window leaks.

To test and remediate air quality problems, we offer a phased approach to identify the problem rapidly and cost-effectively.


For tenant space – 1 day or less

For entire buildings – 1 to 4 days

  • We identify complaints through preliminary discussion with occupants and building services personnel.
  • Thorough inspection of HVAC Systems and occupied spaces.
  • Direct reading instrument testing/sampling for temperature, relative humidity, carbon dioxide, carbon monoxide, and volatile organic compounds (VOC).
  • Limited testing/sampling for highly suspect agents, such as mold, bacteria, chemical, insects, and dust.
  • A formal report identifying problems and recommended corrective measures, OR recommendations for additional tests based on initial findings.  In 70-80% of the time, we can identify the problems in the Phase I survey.


Where situations cannot be resolved by a Phase I evaluation, and the extent of the problem is greater than anticipated, or more testing/sampling and evaluation is necessary; a Phase II Investigation would be performed. Each situation is unique but the following are some of the tests that could be performed.

  • More extensive examination of the interior of the HVAC System, including opening ductwork and test for molds, bacteria, or chemicals.
  • Testing/sampling and analysis of airborne bacteria/fungi (Bioaerosols), Mycotoxins, or Endotoxins.
  • Microscopic assays – Air-O-Cells and Transparent Tape Imprints for mold, bacteria, fibers, dander, or pollen.
  • Particulate assays – microscopic identification of fibers, pollens, fungi, or asbestos.
  • Chemical assays – Volatile Organic Compounds (VOC’s), specific chemicals and identification of unknowns including Industrial Hygiene.
  • Indoor allergens – dust mites, cat and dog dander, cockroach allergens, and endotoxins.
  • Final formal report identifying problems and solutions.
