Which published standard focuses on the ergonomic aspects of thermal environments?

ISO 7730 is the correct choice because it provides guidelines on the evaluation of thermal environments, specifically addressing the ergonomic aspects of thermal comfort for occupants in indoor spaces. This standard outlines methods to measure and assess thermal comfort based on factors such as air temperature, radiant temperature, humidity, and air speed, along with individual factors like clothing and metabolic rate. By focusing on these variables, ISO 7730 helps ensure that indoor environments support the well-being and productivity of individuals.

In contrast, ISHRAE 55 primarily focuses on thermal comfort but is more centered on the design and operational aspects rather than on comprehensive ergonomic evaluations. The "Indoor Environment Input Parameters" does not specifically address ergonomic aspects of thermal environments but rather encompasses a broader range of indoor environmental qualities. The "EPA Compendium of Air Pollutants" pertains to air quality and pollution, which, while important, is not focused on thermal ergonomics.
