LEED AP with Operations and Maintenance (O+M ) Practice Exam

Which two components can improve indoor air quality according to the enhanced credit requirements?

1. Filtration and HVAC maintenance

2. Air circulation and lighting

3. Noise reduction and HVAC systems

4. Space layout and signage

The correct answer is: Filtration and HVAC maintenance

The enhancement of indoor air quality is crucial for the health and comfort of building occupants, and filtration as well as HVAC maintenance are two key components that can significantly contribute to this goal. Filtration systems help to remove airborne pollutants, allergens, and particulate matter from indoor environments. By employing high-efficiency filters, buildings can capture a greater amount of dust, pollen, mold spores, and other harmful particles that may affect air quality. Regular maintenance and replacement of these filters are essential to ensure they function effectively and don’t become clogged, which can lead to inadequate air quality and increased energy consumption. In addition to filtration, proper HVAC maintenance plays a vital role in maintaining indoor air quality. This includes routine checks on the HVAC system’s components such as air ducts, fans, and coils to ensure they are clean and operating efficiently. Well-maintained HVAC systems are less likely to recirculate contaminants and are more effective at providing fresh outdoor air, balancing humidity levels, and controlling temperature, all of which contribute to a healthier indoor environment. Enhancing air quality through these methods not only supports the comfort and well-being of occupants but can also contribute to the sustainability goals of a building, encapsulated in the LEED framework. Therefore, focusing on filtration and HVAC maintenance
