Indoor air

Indoor Air Quality or IAQ
Indoor air quality or IAQ refers to the level of environmental pollutants inside homes and buildings. Good IAQ provides clean air for its occupants with minimal exposure to breathable pollutants.

Indoor Air Pollution: Chemical, physical, or biological contaminants in indoor air.

"Indoor air pollution" in homes and offices has been studied extensively in recent years--with sometimes alarming conclusions that have led the building industry to rethink many aspects of design and choice of materials.

Indoor air pollution
The lack of ventilation indoors concentrates air pollution where people are most exposed to them.

Indoor Air Quality (IAQ) (B):
Indoor Air Quality refers to the contents of interior air that could affect the health and comfort of occupants. Acceptable IAQ is air in which there are no known concentrations of harmful contaminants ...

Indoor Air Quality - A measure of the value or comfort of people with the air they breathe inside buildings and homes.

Indoor Air: The air that people breathe inside a built environment.
Indoor Air Pollutant: Particles of dust, fibers, mists, bioaerosols, and gases or vapors.
Indoor Climate: Temperature, humidity, noise, and lighting inside a structure.

Indoor Air Pollution: Air pollutants that occur within buildings or other enclosed spaces, as opposed to those occurring in outdoor, or ambient air.

indoor air : Breathing air inside a habitable structure, often highly polluted because of lack of exchange with fresh oxygen from outdoors.

Indoor Air Quality (IAQ) - Indoor air that contains no known contaminants at harmful concentrations and with which a substantial majority of the people exposed to the air do not express dissatisfaction.

Definition (english only)
Chemical, physical or biological contaminants in the air inside buildings and other enclosed spaces occupied by humans.

Re-entry: In indoor air programs, refers to air exhausted from a building that is immediately brought back into the system through the air intake and other openings.

The rate at which indoor air enters and leaves a building. Expressed as the number of changes of outdoor air per unit of time (air changes per hour (ACH), or the rate at which a volume of outdoor air enters in cubic feet per minute (CFM).

Re-entry: (In indoor air program) Refers to air exhausted from a building that is immediately brought back into the system through the air intake and other openings.

Air Exchange Rate The rate at which outside air replaces indoor air in a given space. Air Handling Unit Equipment that includes a fan or blower, heating and/or cooling coils, regulator controls, condensate drain pans, and air filters.

Ambient air usually means outdoor air (as opposed to indoor air). Analyte A chemical for which a sample (such as water, air, blood, urine or other substance) is tested.

There are other sources of indoor air pollution by VOC’s however, including wood products that use formaldehyde as a binder. Fortunately, low- or no-VOC substitutes are becoming more common.

Energy Recovery Units - Mechanisms that extract energy from the indoor air (warm air in winter, cool air in summer) and transfer it to the fresh incoming air.

Ambient - Surrounding. Ambient air usually means outdoor air (as opposed to indoor air).

decipol
Unit of perceived air quality: air on mountains or the sea has a decipol = 0.01; city air with moderate air pollution has a decipol = 0.05- 0.03; acceptable indoor air quality has decipol = 1.4 (for 80% satisfaction).

Formaldehyde: A organic compound/chemical that is toxic to human health when exposed on a widespread basis. Formaldehyde is used frequently in adhesives and conventional building products and contributes negatively to indoor air quality.
