Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
It mandates an air quality management plan, ventilation during the construction phase, natural light for certain occupancies, and prohibits smoking indoors. It also limits pollutants in certain rooms, requires filters for air conditioning systems, and regulates emissions from fireplaces, fuel-burning appliances, and gas appliances.
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
To reduce draft risk at temperatures below 22.5 °C (72.5 °F), air speed due to the HVAC system must be 0.15 m/s (30 ft/min) or below. The vertical air temperature difference between ankle and head is limited to 3 °C (5.4 °F) for seated occupants and 4 °C (7.2 °F) for standing occupants. [ 6 ]
Indoor air pollution contributes to risk factors for diseases like heart disease, pulmonary disease, stroke, pneumonia, and other associated illnesses. [39] For vulnerable populations, such as children and elderly populations, who spend large amounts of their time indoors or indoor air quality can be dangerous.
A 2002 study found that "Each 10 μg/m 3 elevation in fine particulate air pollution was associated with approximately a 4%, 6% and 8% increased risk of all-cause, cardiopulmonary, and lung cancer mortality, respectively."

In 1977, the EPA published a document which detailed the Air Quality Criteria for lead. This document was based on the scientific assessments of lead at the time. Based on this report (1977 Lead AQCD), the EPA established a "1.5 μg/m 3 (maximum quarterly calendar average) Pb NAAQS in 1978."
