An indoor environment is an ecosystem that encompasses everything that impacts the indoor quality of commercial, public, and residential buildings, other structures, their contents and the occupants.
Indoor Environmental Quality (IEQ)
Indoor quality is the state or condition of the indoor environment. It is influenced by the outdoor environment, the surrounding structure and its systems, the building contents, and the activities of occupants.
Indoor environmental quality (IEQ) has been used as a synonym for indoor air quality (IAQ). However, when you consider the indoor environment and its effect on occupants, you need to consider more than the air.
