What is the primary focus of ASHRAE?

The primary focus of ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) is to advance the practices and technologies related to heating, ventilation, air conditioning (HVAC), and refrigeration. Established in the early 20th century, ASHRAE is dedicated to promoting sustainability and efficiency within these fields, which are crucial for creating comfortable indoor environments and reducing energy consumption. The organization publishes research, develops industry standards, and provides education to professionals in the HVAC and refrigeration industries, emphasizing innovations and advancements that improve building performance and occupant health.

The other options do not accurately reflect ASHRAE's mission or activities. Assessing fire hazards in buildings pertains more to fire safety organizations, while developing road safety regulations is the domain of transportation and public safety agencies. Enforcing building codes falls under the purview of local and state governments rather than a specific professional organization that focuses on HVAC and refrigeration technology.
