Scope of Work: Indoor Air Quality Testing

Overview:

​​EEC performed an Indoor Air Quality inspection on an office park with 10 office buildings in Tampa, Florida. This was a study requested by an insurance company underwriter as part of the policy renewal. After inspecting all 10 buildings for potential signs of mold, including air conditioning vents and air handler unit coils and pans, EEC conducted a full-scale air analysis. Each building was tested for temperature, relative humidity and carbon dioxide level. Some offices had at dirty air conditioning supply vents. EEC did not observe anything that appeared to be mold on any of the air conditioning supply or return vents. We observed that some suites had water stained ceiling tiles. The outside air non-viable fungal result was 667 spores per cubic meter of air sampled (spores/m3) with the most predominant species being Basidiospores at 227 spores/m3 (34% of the sample total), followed by Cladosporium at 207 spores/m3 (31% of the sample total) and Aspergillus/Penicillium-Like at 180 spores/m3 (27% of the sample total). The eight indoor air quality samples for non-viable fungal samples were determined to be satisfactory when compared to the outside air result. EEC recommended the preventative maintenance activities for air conditioning systems should be continued as they are working for this particular location.

Scope of Work: Indoor Air Quality Testing

Overview:

The sampling was requested by the landlord due to employee concerns and because of an odor in the facility. The testing was performed to insure acceptable air quality for the employees. Non-Viable Fungal Air samples were collected using the Air-O-Cell cassette sampling method. The cassettes are connected to an air pump that draws air through the filter media at a rate of 15 liters per minute. The air quality for fungus was tested and determined to be acceptable. EEC determined that the source of the odor was from the coil and pan not draining properly. It is possible that this unit was not cleaned regularly. EEC recommended cleaning the coil and drain pan and adjusting the drain line as necessary. In addition, EEC recommended inspecting the duct work to determine if it needs to be cleaned.
