Visual comfort is not typically considered a key component of IEQ, although it can contribute to overall occupant well-being.

The recommended temperature range for thermal comfort in indoor environments is generally considered to be between 20-24°C (68-75°F).

Natural ventilation is not a source of indoor air pollution, but rather a strategy for improving indoor air quality by introducing fresh outdoor air.

The recommended relative humidity range for indoor environments is generally considered to be between 40-60%.

Increasing background noise is not a strategy for improving acoustic comfort, as it can mask important sounds and make it difficult to communicate.

The recommended illuminance level for general office work is generally considered to be between 500-750 lux.

Lower energy consumption is not typically considered a direct benefit of good IEQ, although it can be achieved through strategies that improve IEQ, such as natural ventilation and energy-efficient lighting.

The recommended ventilation rate for indoor environments is generally considered to be 15 cfm per person.

Oxygen is not an indoor air pollutant, as it is essential for human life.

The recommended maximum concentration of carbon dioxide (CO2) in indoor environments is generally considered to be 1000 ppm.

Smoking indoors is not a strategy for improving indoor air quality, as it releases harmful pollutants into the air.

The recommended maximum concentration of particulate matter (PM2.5) in indoor environments is generally considered to be 10 μg/m³.

Natural ventilation is not a common source of noise pollution in indoor environments, as it typically introduces fresh outdoor air without significant noise.

The recommended maximum reverberation time for indoor environments is generally considered to be 1.0 second.
