5 Things About Indoor Environmental Surveys You May Not Know


Indoor environmental surveys begin with air quality and include other components of indoor living or working space. Surveys are based on the type of indoor environment. A home or multi family residential building may have different requirements than commercial buildings.

Hospitals, restaurants, hotels, retail establishments and industrial buildings all have separate standards to assess their indoor air quality. Compliance is mandatory for the health and safety of employees and others who use the facilities.

The following items are generally surveyed in most Indoor Environmental Surveys:

  • Thermal comfort
  • Filters
  • Flooring and windows
  • Humidity level
  • Exposure to lead paint and/or asbestos

Thermal comfort is just as important as  during Indoor Environmental Surveys

This is the base for any indoor air quality survey in any building. The heating ventilation and air conditioning (HVAC) system must work efficiently to provide maximum comfort. Thermostats must be adjusted to a comfortable level for occupants on a year-round basis.

Most rooms in a home should have six to eight complete air changes per hour. This is the average Air Change Rate (ACR) for a residence. The rate is different for commercial buildings based on occupancy and the size of rooms measured in cubic feet. The ACR indicates that the HVAC system is circulating air efficiently.

Air Filters Are Often Overlooked…

Air circulation must be free of harmful particles. This includes dust, pet dander, pollen, smoke and noxious odors. Rooms should be smoke-free in all commercial and industrial buildings. Smoke alarms should be used in all residences.

Filters in the HVAC system collect the harmful particulates and prevent them from circulating through the ducts. An audit of indoor air quality includes inspection of the filter system.

Most conventional filters are easy to change on a seasonal basis. New filters should replace old ones when homes change from heating to air conditioning.

Windows and floors contribute to Air Quality!

Double and triple pane windows hold out the cold and keep in the heat. They enable the HVAC system to work more efficiently. An indoor audit will check windows and doors along with weather stripping in certain areas of the country. This applies to residential and commercial building surveys.

The use of tinted film or glass on windows to cut down on heat or intense sunlight is also important. Many newer office buildings use reflective glass that cuts down on glare inside. This improves air quality by preventing excessive heat from sunlight. The HVAC system works at peak efficiency while saving energy.

Flooring is a component of residential and commercial building surveys. Carpeting provides warmth while tile and wood are much cooler. Carpeting holds dander, dust and pollen. Carpets should be vacuumed frequently to keep these pathogens out of the air. Hard surface flooring is easy to sweep and vacuum.

Humidity levels affect more than comfort….

Good air quality depends on a moisture level that is not too humid or too dry. Some homes and commercial buildings in arid areas need humidifiers. Conversely, rooms in humid regions will benefit from a dehumidifier. Ideal humidity is generally 40% to 50%.

High humidity leads to the growth of mold and fungus on walls and enclosed spaces. This includes HVAC ducts. A very dry environment often encourages dust particles to float in the air.

Asbestos and lead are a real consideration in older homes…

Older buildings are immediately checked for lead-based paint and asbestos in vinyl floors. Lead paint and asbestos must be removed by professionals wearing hazmat gear. Inhaling particulates from either substance is harmful to health.
