Which standard should projects follow when selecting carbon dioxide sensors?

ASHRAE Standard 90.1
ASHRAE Standard 62.1
ASHRAE Standard 62.2.2010
ASHRAE Standard 55

The correct answer is: ASHRAE Standard 62.2.2010

When selecting carbon dioxide sensors, the appropriate standard to follow is ASHRAE Standard 62.2-2010. This standard is specifically focused on ventilation and indoor air quality in residential buildings, addressing the need for adequate outdoor air to support occupant health. It provides guidelines on acceptable indoor air quality levels, including the management of carbon dioxide levels, which is essential for ensuring the well-being of occupants in residential settings. ASHRAE Standard 62.1, while relevant to commercial buildings and indoor air quality, serves a different purpose by focusing on non-residential applications. ASHRAE Standard 90.1 is primarily concerned with energy efficiency in buildings and does not specifically address CO2 sensor installation for ventilation control. ASHRAE Standard 55 focuses on thermal comfort and does not cover air quality or CO2 levels. Therefore, ASHRAE Standard 62.2-2010 is the correct reference point for projects needing to implement carbon dioxide sensors to maintain healthy indoor environments, particularly in residential contexts.
