40,000 people seeking ideas to grow by.
In spite of continuing economic challenges, thousands of HVACR professionals flocked to Chicago’s McCormick Center for AHR Expo 2012. Nearly 2,000 companies showcased their latest products and technologies on more than 429,000 sq.ft. of exhibit space. This made the AHR Expo the largest event in its 82-year history. Yes, that meant more walking, but there were also more new products to see, so it was worth the sore feet.
The AHR Expo is never a disappointing event. Every year, it features innovative products, and we always meet interesting people. Expo officials’ final report said the show drew nearly 40,000 contractors, engineers, facility managers, and other HVACR professionals. Contracting Business.com editors spent three days covering the event, and we now present our “travelogue” of activity, to give you an idea of the products and people that made 2012 AHR Expo a winner.
Among some of the really interesting products we saw and news we uncovered were the following: The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) reported that 2,800 people attended the ASHRAE Winter Conference, held Jan. 21-25, as part of AHR Expo. The top-attended sessions were selection of proper chiller technology; thermal displacement ventilation applications; heat pump optimization; air source versus ground source heat pump systems; integrated design energy retrofits; and water-cooled VRF systems. Other conference highlights included the technical plenary, which drew 600 attendees, with its focus on Chicago’s energy-efficient economic model for sustainability. ASHRAE announced a brand repositioning with a refreshed logo, a new tagline, and a change to using only its acronym.
“ASHRAE’s original commitment to HVACR engineering excellence remains resolute, even as the Society continues to expand its influence into all facets of building design, construction, reconstruction, and operation,” ASHRAE President Ron Jarnagin said. “Just as integrated design is the cornerstone of sustainable buildings, ASHRAE members create an integrated body of knowledge to make buildings as high performing as possible.”
