The link between symptoms of office building occupants and in-office air pollution : The Indoor Air Pollution Index

The Indoor Air Pollution Index (IAPI) has been developed to put an end to communication concerns among building tenants, building managers, and IAQ investigators. That index, simple and easy to understand, satisfies the 3 criteria of environmental indices because it relates to occupant symptoms, is easy to communicate to the consumer and can be used as an environmental and management tool for reducing in-office air pollution effectively.The index uses a unitless single number between 0 (lowest pollution level and best IAQ) and ten (highest pollution level and worst IAQ). It provides a relative measure of indoor air pollution for office buildings, ranks office indoor air pollution relative to the index distribution of the US office building population.
