What does the ASHRAE 62 Standard define?

The ASHRAE 62 Standard specifically focuses on ventilation and indoor air quality. It establishes guidelines that ensure acceptable indoor air quality by detailing the required outdoor air ventilation rates necessary for different types of buildings and occupancy types. By defining good indoor air quality, the standard emphasizes the importance of minimizing harmful contaminants that could negatively affect the health and comfort of building occupants. This means that effective ventilation is not just about removing pollutants but also ensuring the air remains clean and safe to breathe, thus highlighting the vital role of adequate indoor air quality.

While the other options touch on related topics, they do not fully encompass the scope of ASHRAE 62. For instance, specifying maximum allowable levels of pollutants, discussing outdoor air quality standards, or outlining requirements for air conditioning systems does not capture the standard's comprehensive approach to indoor air quality through ventilation principles.
