The 2005 AHR Expo and ASHRAE Winter Meeting comes to Orlando, Fla., to exhibit the latest products, services, standards and a little Disney fun.



ORLANDO, Fla. - The organizers of the AHR Expo and ASHRAE winter meeting must like Disney-style entertainment, or at least warm weather.

In 2004, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, and expo officials held their joint annual events in Anaheim, Calif., best known for orange groves until the opening of Disneyland in 1955 forever changed the formerly small town.

This year, both will be held in Orlando, Fla., another small town that was forever changed by the opening of Walt Disney World in 1971.

While the expo's impact likely won't be as great as the opening of that mega-attraction, it will bring thousands of attendees and exhibitors to the Orange County Convention Center for what is expected to be one of the largest AHR shows in recent years.

"We are very excited about this overwhelming response from the industry so far in advance of the event," Clay Stevens, president of the International Exhibition Co., which manages the show, said in May 2004.

More than 321,000 square feet of exhibit space has been reserved so far, which Stevens said was "especially gratifying since this is the first time the AHR Expo has been held in Florida."

He said there were several reasons for the positive response from exhibitors, including the addition of attendees from the Southeast U.S., many of whom have not visited an AHR Expo before.

"The improving economy is certainly a key factor. In addition, we believe that an increasing number of companies are confident that they will receive a good ROI (return on investment) participating in the world's leading HVACR event."

Winter meeting

ASHRAE's winter meeting will take place Feb. 5-9 at the Wyndham Palace Resort and Spa, located on Disney World property.

With Florida being one of the warmest and most humid U.S. states, ASHRAE educational sessions on dealing with the mold and mildew problems common in buildings located in such climates will likely be of interest to many attendees.

"Designing, constructing and operating buildings in locations such as Florida is difficult, due to the hot and humid climate," said Kelley Cramm, who heads the society's program committee. "Our goal is to make engineering these climates easier by providing guidance on humidity-control issues, techniques and equipment."

One planned Feb. 6 seminar will deal with case studies on mold and mildew outbreaks in Florida. It will include a presentation on using mechanical systems to contain mold growth in hotels. In a Feb. 8 session, ways to achieve more success when using dehumidifiers will also be discussed.

A Feb. 6 session will tackle design issues in hot climates including information on walls, roofs, interior finishes and mechanical systems and their effects on indoor air quality, durability and moisture control.

Air-to-air energy-recovery systems and their use with ASHRAE's ventilation standard will also be addressed Feb. 6. Simply using larger HVAC equipment does not typically improve humidity control, but properly using energy-recovery systems may help, according to the officials who will host this seminar.

The society's first design guide for small office buildings will be introduced at a Feb. 7 session. Using the new guide, building owners can save 30 percent of their energy costs, ASHRAE officials said.

A special session commemorating the society's 100th anniversary is also planned.

Sessions

Here are some of the other educational events planned.

"Recent Advances in Duct Design," 8 a.m. Feb. 6. Stephen A. Idem, Ph.D., of Tennessee Technological University will lead this discussion. Data on pressure loss and air leakage will be presented. The European approach to ductwork quality and the savings and performance possibilities of duct-loop systems will also be explored.

"Low-frequency HVAC Noise in Buildings and its Effects on the Comfort and Productivity of the Occupants," 10:15 a.m. Feb. 6, will explore the data from the research done by ASHRAE and others on the effect HVAC system noise has on office workers and others. Studies from around the world will be presented, including the two undertaken by ASHRAE.

"Blast, Chemical, Biological and Radiation Attacks: What is ASHRAE's Role?" 10:15 a.m. Feb. 6. Since the Sept. 11, 2001, attacks in New York and Washington, D.C., terrorism is now a concern for many building owners as well as occupants. This session will explore, what, if any, role ASHRAE should have in providing advice on dealing with these issues. The need for a guide on handling occupants, maintaining building operations or construction measures designed to reduce the likelihood of an attack are among the planned topics.

"IAQ in Industrial Facilities," 10:15 a.m. Feb. 7, will tackle the ventilation issues required in preserving good air in factories and other such places. Different standards and considerations apply for offices and commercial spaces, and this seminar will discuss them both.
