). The Society, organized into Regions, Chapters, and Student Branches, allows exchange of HVAC&R knowledge and experiences for the benefit of the field's practitioners and the public. ASHRAE provides many opportunities to participate in the development of new knowledge via, for example, research and its many Technical Committees. These committees meet typically twice per year at the ASHRAE Annual and Winter Conferences. A popular product show, the AHR Expo, is held in conjunction with each Winter Meeting. The Society has approximately 50,000 members and has headquarters at Atlanta, Georgia

 and guidelines relating to HVAC systems and issues. These standards are often referenced in building codes, and are considered useful standards for use by consulting engineers, mechanical contractors, architects, and government agencies. These are legally unenforceable, but commonly accepted standards for architects and engineers.

Examples of some ASHRAE Standards are:
  • Standard 34 – Designation and Safety Classification of Refrigerant
    A refrigerant is a substance used in a heat cycle usually including, for enhanced efficiency, a reversible phase change from a liquid to a gas. Traditionally, fluorocarbons, especially chlorofluorocarbons, were used as refrigerants, but they are being phased out because of their ozone depletion...

It includes peer-reviewed articles on the practical application of HVAC&R technology, information on upcoming meetings and product shows, classified and display advertising, and editorials. Members of ASHRAE receive the magazine and the current year's volume of the ASHRAE Handbook as membership benefits. ASHRAE also publishes many books, ASHRAE Transactions, and the International Journal of HVAC&R Research.

, and have held an annual meeting since 1895. Until 1954 it was known as the American Society of Heating and Ventilating Engineers (ASHVE); in that year it changed its name to the American Society of Heating and Air-Conditioning Engineers (ASHAE). Its current name and organization came from the 1959 merger of ASHAE and the American Society of Refrigerating Engineers (ASRE). The result, ASHRAE, despite having 'American' in its name, is an influential international organization. Amongst other international activities, it helps organize international events.

Headquarters Renewal

In 2006, ASHRAE adopted sustainability

ASHRAE's goals could only be achieved through collaboration, innovative use of technology, and aggressive partnerships with product and equipment manufacturers, many of which are based in Georgia. As the leader in codes and standards for the building industries’ engineers, the renovation and addition to ASHRAE’s existing building incorporated the membership's expertise from around the country to collaborate with the local design firm, their consultants, and the general contractor. Throughout the design and construction process the team evaluated numerous building components, including mechanical equipment, electronic systems, as well as over $1 million of donated equipment.

The renovation of the existing headquarters building included the reconfiguration of existing space and an additional wing. The existing windows, which had been replaced and upgraded in the late 1990s, remained. The new entrance was designed and relocated to the rear of the building to provide a quieter entrance. Project requirements for the facility included a new training center, meeting and education spaces for their members, a technical library, offices, collaborative workspaces for personnel, and a shipping and receiving area. The facility incorporates open and flexible planning to take advantage of natural light and efficient planning methods that increased the total number of future staff above previous levels by 25% within a reduced office footprint. Enclosed offices for 95% of staff were eliminated and replaced with furniture-based work station layouts which conserved space, provided exterior views for all employees, and fostered collaboration. A new training center was added to respond to the organization’s growing outreach and continuing education needs.
