What is acceptable indoor air quality?

• 62.1-2010, Ventilation for Acceptable Indoor Air Quality. This standard specifies recommended outdoor air ventilation rates. The recommended outdoor ventilation rates are based on olfactory studies, and acceptable indoor air quality is met when 80% or more of the exposed people do not express dissatis-faction.

Why is indoor air quality important?

• Indoor air quality (IAQ) is a major concern to businesses, schools, building managers, tenants, and workers because it can impact the health, comfort, well-being, and productivity of the building occupants.

How is air quality determined in a building?

• Air quality may be determined by the site of the building, its original design, renovations, whether air handling systems have been maintained, occupant densities, activities conducted within the building, and the occupants’ satisfaction with their environment. IAQ problems can arise from a single source or any combination of factors.

How can a building owner help with IAQ problems?

• A building owner or manager may first want to consult local, state, or federal government agencies (e.g., education, health, environmental protection, or agriculture agencies) for assistance or direction in solving IAQ problems. These governmental agencies may be able to help an employer identify the types of experts who could best assist them.
