What is the primary goal of ASHRAE Standard 62-1989 regarding ventilation?

The primary goal of ASHRAE Standard 62-1989 is to specify minimum outdoor air ventilation rates to effectively remove indoor air contaminants. This standard emphasizes the importance of providing adequate ventilation in occupied spaces to maintain indoor air quality, which is crucial for occupant health and comfort. The effectiveness of ventilation in diluting and removing airborne pollutants, including those from indoor sources and activities, is a core aspect of this standard.

By focusing on minimum ventilation rates, ASHRAE Standard 62-1989 establishes guidelines that help HVAC practitioners determine the necessary amount of fresh outdoor air required for various types of spaces, ensuring that pollutants do not accumulate to levels that could pose health risks. Additionally, the standard supports the importance of balancing indoor air quality with the energy considerations of ventilation systems to achieve a safe and healthy environment for occupants.

In contrast to other goals listed in the options, such as improving energy efficiency or ensuring comfort, the focal point of ASHRAE Standard 62-1989 remains on providing adequate outdoor air to combat indoor pollution, which directly impacts the health and well-being of the building occupants.
