In order to qualify for the Enhanced Indoor Air Quality Strategies credit, what must be done to the ventilation systems?

  1. Replace the ducts

  2. Implement regular inspections

  3. Address filtration for outdoor air

  4. Install sound barriers

The correct answer is: Address filtration for outdoor air

To qualify for the Enhanced Indoor Air Quality Strategies credit in the LEED AP with Operations and Maintenance (O+M) framework, addressing filtration for outdoor air is essential. This involves ensuring that the ventilation systems have effective air filtration processes in place to improve the quality of air being introduced into the indoor environment. Filtration systems need to be capable of removing particulates and harmful substances from the outdoor air before it enters the building. Implementing proper filtration reduces the concentrations of pollutants and enhances overall indoor air quality, which is a critical factor in promoting occupant health and comfort. The other options, while they may relate to aspects of ventilation or noise control, do not specifically address the requirements for indoor air quality improvement as outlined for this credit. Regular inspections can help maintain systems but do not directly enhance air quality. Duct replacement may be necessary in some circumstances but is not a requirement for this credit. Sound barriers pertain more to noise control rather than indoor air quality management. Thus, focusing on filtration is the most relevant action to qualify for the Enhanced Indoor Air Quality Strategies credit.
