| Acceptable Indoor Air Quality: |
Indoor air, in which there are no known contaminants at harmful concentrations and with which a substantial majority (usually 80%) of the occupants exposed do not express a dissatisfaction. |
| Air Ventilation and Recirculation: |
Outdoor air plus any recirculated indoor air that has been treated (filtered) for the purpose of maintaing acceptable indoor air quality. |
| Daseline Data: |
a) Building and environmental information which are gathered to determine the accumulations of biological, chemical, toxins and other physical properties. b) The baseline data of acceptable indoor air quality, including thermal, physical and respirable measurements. c) The baseline data of acceptable indoor air quality verses outside air quality. d) The efficiency ratio of a ventilation system to operate and separate contaminates from indoor air. e) The energy efficiency of a building over time.

| Ventilation for Acceptable Indoor Air Quality: |
Ventilation for Acceptable Indoor Air Quality are the design, engineering, installation and maintenance of a heating, ventilation and air-conditioning system as found in ASHRAE Standard 62-1989. The Ventilation for Acceptable Indoor Air Quality design requirements recommend 15 cubic feet of air per minute (CFM) per person of fresh outdoor air into buildings. |
