What is one key requirement for maintaining good Indoor Air Quality (IAQ)?

  1. Maximizing temperature fluctuation

  2. Controlling pollutant sources

  3. Using low-quality building materials

  4. Minimizing the use of natural light

The correct answer is: Controlling pollutant sources

Controlling pollutant sources is a fundamental requirement for maintaining good Indoor Air Quality (IAQ). This involves identifying and minimizing any sources of pollution within a building that can negatively affect the health and comfort of its occupants. Common sources of indoor air pollutants include volatile organic compounds (VOCs) from paints and furnishings, dust and allergens, and emissions from heating and cooling systems. By effectively managing these sources through proper maintenance, filtration, and choices in materials and products used within the building, the overall quality of the indoor environment can be significantly improved. In contrast, maximizing temperature fluctuation can lead to discomfort and potential health issues, while using low-quality building materials often contributes to increased off-gassing of harmful substances. Minimizing the use of natural light can adversely affect both the mood and health of occupants, as well as limit the natural ventilation that aids in improving IAQ. Focusing on controlling pollutant sources directly addresses one of the most critical aspects of creating and maintaining healthy indoor spaces.
