LEED Green Associate Practice Test

Which of the following is an enhanced indoor air quality strategy?

1. Install temporary entryway systems

2. Monitor carbon dioxide levels

3. Limit outdoor air intake

4. Reduce air filtration efficiency

The correct answer is: Monitor carbon dioxide levels

Monitoring carbon dioxide levels is indeed an enhanced indoor air quality strategy. This approach focuses on ensuring that indoor spaces maintain a healthy level of air quality by minimizing the concentration of carbon dioxide, which can indicate insufficient ventilation or the presence of high occupancy levels. By monitoring these levels, building managers can make informed decisions regarding ventilation and air exchange rates, thereby improving overall indoor air quality for the occupants. The other options, while they may contribute to indoor air quality in different ways or serve other purposes, do not specifically align with enhancing indoor air quality as effectively as monitoring carbon dioxide levels. For instance, temporary entryway systems can help mitigate the transfer of contaminants into the building, but they are more oriented toward limiting the introduction of pollutants rather than maintaining optimal air quality. Limiting outdoor air intake may reduce exposure to outdoor pollutants, but it can also contribute to elevated indoor CO2 levels if not carefully managed. Reducing air filtration efficiency would counteract efforts to improve indoor air quality, as it would allow more particulate matter and pollutants to circulate within the indoor environment.
