Members of ASHRAE had to deal with a heat wave in San Antonio when the association held its annual conference there June 23-27.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers said the triple-digit heat reminded attendees of the role they play in shaping the building environment.

Some 1,560 people attended the conference, which was the highest since ASHRAE’s 2007 conference in Long Beach, Calif. Those attendees stayed cool by participating in a number of technical programs — held indoors.

ASHRAE offered nearly 280 presentations, eight educational courses and several social events. The meeting also featured more than 400 meetings of technical, standards and standing committees.

Top-attended sessions in the technical program were featured in the mini-conference on integrated building controls. This included lessons learned from mistakes in integrated controls; how to use control specification fundamentals; and case studies of an energy-retrofitted office building.

There was also a great deal of interest in modeling from ASHARE attendees. Some of the popular seminars discussed improving consistency in building energy modeling. One course explored load calculations and used the ASHRAE headquarters building in Atlanta as an example.

Also offered were two professional development seminars and six short courses from the ASHRAE Learning Institute. The most popular courses were “Complying with Standard 90.1-2010: HVAC/Mechanical” and “Energy Management in New and Existing Buildings.”

ASHRAE’s 2013 winter conference will takes place Jan. 26-30 in Dallas. It will be held in conjunction with the 2013 AHR Expo.
