ASHRAE 2011 Winter Conference Sees Highest Attendance In Years
March 4, 2011

The 2011 American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Winter Conference saw its highest attendance numbers in years, as well as the announcement of updated energy savings figures for ASHRAE’s energy standard.

Some 3,400 people attended the Conference, held Jan. 29th-Feb. 2nd, in Las Vegas, Nev.; of that number, 400 were first-time attendees. Also taking place in conjunction with the meeting was the Air-Conditioning, Heating, Refrigerating Exposition, which attracted over 54,000 registered visitors and exhibitor personnel. The Show was by far the largest and best attended AHR Expo in the Western states, with more than 1,900 exhibiting companies and their 20,000 exhibiting personnel—the second largest number of exhibiting companies in the Show’s history. Overall, the 2011 AHR Expo was the second largest held outside of Chicago.

The ASHRAE Conference offered a technical program with nearly 300 sessions, 20 educational courses and numerous social events. The meeting also featured more than 600 meetings of technical, standards and standing committees, developing guidance for the future of the industry and ASHRAE.

The biggest buzz at the Conference centered on the latest energy saving figures of ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, which provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. Without plug loads, site energy savings are 32.6 percent and energy cost savings 30.1 percent. Including plug loads, the site energy savings are estimated at 25.5 percent and energy cost savings 24 percent. The standard is written in mandatory code language and offers code bodies the opportunity to make a significant improvement in the energy efficiency of new buildings, additions and major renovations.

Additional sessions from the Technical Program are part of ASHRAE’s Virtual Conference, which provides access to more than 250 presentations and PDFs of posters. Register or access presentations at
