Case Study Airport spreads its wings S AT A GLANCE Pittsburgh International Airport (PIT) tapped Honeywell to supply the HVAC and fire alarm systems for its new terminal. When that terminal opened in 1992, it had 17,000 HVAC points, 9,000 fire alarm points, 155 Honeywell Excel Plus HVAC controllers, 550 MCL variable air volume zone controllers, and 30 FS90 fire alarm panels. All of these systems were integrated into a Graphics Central. Six years later, the fire alarm system was expanded to include all of PIT’s remote buildings in the fire protection platform, bringing an additional 20 FS90 panels. The year after, 80 XL50 controllers were added to control the HVAC for the air bridges. In response to the Sept. 11, 2001, terrorist attacks, PIT adopted Honeywell’s Enterprise Buildings Integrator (EBI), an ituated on a 10,000-acre site located 20 miles west of the city, Pittsburgh International Airport (PIT) accommodates almost 10 million travelers each year. PIT services about 210 non-stop flights per day to 59 destinations. With new routes being added each year and growing development surrounding the airfield, the airport is a major economic engine for southwestern Pennsylvania. Expansion In the late 1980s the Allegheny County Airport Authority recognized the need to expand and update its facilities to accommodate the growing number of domestic and international flights at PIT. The airport’s original terminal, built in 1952, was considered one of the most modern and spacious in the country when it first came online, second only in size to JFK International Airport in New York. However, despite the addition of an international wing in 1972, along with several new docks and rotundas throughout the 1980s to increase the number of gates, the capacity of the original terminal still proved inadequate. “We needed a larger terminal with modern jetways not only for the growing number of flights, but also for the larger aircraft passing through the airport,” said Tom Long, director of maintenance and a 38-year PIT employee. “We also knew the original facility contained asbestos, as well as old building control equipment that were not able to be upgraded.” Construction on the new PIT terminal began in 1990. It was designed to offer 7.7 million sq ft of air-side space, more than 100 gates, and a mall of more than 100 restaurants and specialty shops. Based on the Honeywell’s more-than-40year relationship with the airport, PIT and its architectural consultants tapped Honeywell to supply HVAC and fire alarm systems throughout the new space. When the terminal opened to the flying public in 1992, Honeywell technology helped control more than 17,000 HVAC points and 9,000 fire alarm points throughout the facility. At the heart of the building automation architecture were 155 Honeywell Excel Plus HVAC controllers, 550 MCL variable air volume zone controllers, and 30 FS90 fire alarm panels—all that integrates almost all of PIT’s building systems into a flexible open architecture. EBI is helping PIT attain its goal of having complete control of building operations from one centralized location. PIT and Honeywell continue to work as a team to develop ideas to improve the airport’s operations, systems, and energy management strategies. 46 Consulting-Specifying Engineer • NOVEMBER 2008 Photo courtesy of Pittsburgh International Airport enterprise management system
