Which standards should a project team refer to for thermal comfort in a mechanically ventilated space?

ASHRAE 55-2010
ISO Standard 7730
CEN Standard EN 15251
ASHRAE 62.1

The correct answer is: ASHRAE 55-2010

ASHRAE 55-2010 is the correct reference for establishing acceptable thermal conditions in occupied spaces, particularly for those that are mechanically ventilated. This standard provides guidelines for thermal comfort based on a variety of factors, including temperature, humidity, air speed, and the clothing and metabolic levels of occupants. It aims to ensure that occupants are comfortable throughout different seasons and variations in temperature. ASHRAE 55-2010 outlines the criteria for evaluating thermal comfort, considering both environmental and personal variables. This makes it particularly suitable for a project team focused on indoor environmental quality and comfort within mechanically ventilated spaces. Other standards mentioned, such as ISO Standard 7730 and CEN Standard EN 15251, also address thermal comfort and might be applicable in specific contexts or regions. However, they do not provide the same comprehensive framework specifically tailored for utilizing mechanical ventilation systems. ASHRAE 62.1 primarily concerns ventilation requirements for acceptable indoor air quality rather than explicitly addressing thermal comfort.
