Case Study efficiency and reduces operating costs by integrating core building technology and allowing operators to view and control these functions from a single workstation. With EBI, PIT would be able to tie nearly all building systems into a flexible, open architecture while keeping its existing control equipment in place. After extensive planning, Honeywell completed the installation in 2002 with no system downtime. The EBI system, consisting of two redundant servers and 11 stations, was customized to the airport’s specifications, largely mirroring the look and feel of the old XBSi interface. This minimized the workflow learning curve for operators, allowing them to instantly understand the data presented to them and reduce training time. A demonstration EBI’s effectiveness, according to Long, came during a smoke test conducted by PIT and its fire department not long after Honeywell technicians installed the system. Airport officials wanted to verify how smoke would travel throughout a particular area of the terminal in the event of a fire. To test smoke control capabilities—involving the combined use of fire alarm and HVAC systems—the fire department set up artificial pritchard brown PROTECTING TECHNOLOGY AND THE WORLD. Pritchard Brown, LLC the Industry Leader in Technology, Service, Quality and State-of-the-Art Design for Enclosures and System Integration. • Outstanding reputation for quality and service • Total packaging and testing services by trained professionals • Strategically located to serve markets in all of North and South America • U.L. classified enclosures and U.L. listed base tanks, extensive options and total flexibility • Professional sales and engineering staff • High performance, maintenancefree materials • Building shelters and trust for more than 50 years smoke machines to simulate a blaze in one of the retail stores located along the concourse. When the test was run and the alarm system detected smoke, the HVAC system immediately kicked in, ventilating the area exactly as planned. “It was amazing, there was literally a wall of smoke on one side and clear air on the other,” said Long. “The whole integrated system worked extremely well and gave us great confidence that it was finely tuned.” In addition to HVAC, fire, and security, PIT has integrated other systems onto EBI, including a defibrillator system. If someone in the airport has a heart attack or other medical emergency and a defibrillator unit is taken from its location, an alarm automatically notifies EOC operators of the exact location of the incident, helping emergency responders take action as quickly and effectively as possible. PIT has linked its fire system into all off-site buildings, including hangars, fuel farms, maintenance garages, parking garages, and rental car buildings. It also is exploring ways to tie in data from its closed circuit TV system and Flight Information Display System (FIDS), the network of screens across the airport detailing flight arrival and departure times. “What we want is complete control of our building operations from one centralized location,” Long said. “Linking FIDS into EBI is just another step in that evolution. It will allow us to make changes to the screens across the terminal from the EOC, something we couldn’t do before.” Energy conservation With the reduced number of flights and travelers after Sept. 11, as well as the continual rise in fuel costs, the airport also recognized the need to gain better control of its energy use across its facilities to help offset these pressures. In response, PIT established an energy management team made up of airport management, facilities personnel, and Honeywell consultants that meets on a monthly basis to assess energy conservation opportunities throughout the airport. For example, the rooftop units that heat and cool the airport have been optimized to minimize electrical consumption, escalators and moving walkways are shut down at night when traffic is relatively low, and occupancy sensors have been placed throughout areas of the terminal to minimize lighting use, particularly at night. With Honeywell’s guidance, PIT also is exploring submetering across the terminal to better understand and regulate energy use with tenant organizations, such as retail outlets. As PIT looks to expand its capabilities beyond the airport and tie in building systems at nearby Allegheny County Airport, both managed by the Allegheny County Airport Authority, it will continue to work with Honeywell to support its technology needs. Building shelters—and trust—for more than 50 years.
