What is the purpose of ASHRAE 62.2?

ASHRAE 62.2 serves as a ventilation standard specifically designed for low-rise residential buildings. The purpose of this standard is to ensure acceptable indoor air quality by specifying the minimum ventilation requirements and the appropriate design and performance for ventilation systems. By establishing these guidelines, ASHRAE 62.2 helps to promote healthier indoor environments by addressing the removal of indoor air contaminants and the introduction of fresh outdoor air.

This standard focuses particularly on residential applications, emphasizing the importance of adequate ventilation in homes to mitigate issues related to indoor air pollutants, which can arise from various sources such as cooking, cleaning, and materials used in construction. Proper application of ASHRAE 62.2 contributes to enhanced occupant comfort, health, and safety by ensuring that homes maintain a sufficient supply of fresh air.

In contrast, other options describe standards that focus on different aspects. For instance, building codes are typically broader regulations applicable to all types of buildings and do not specifically address ventilation for residential settings. Energy efficiency standards for appliances focus instead on the performance and energy use of household devices, while green building certification standards assess the overall environmental performance of buildings rather than concentrating solely on ventilation aspects like ASHRAE 62.2 does.
