case study are important to this effort, but so is a strategic range of solutions designed to meet unique challenges. Collaborative, long-term relationships offer an ideal opportunity to develop those strategic solutions. These collaborations will result in signiﬁcant cost savings and enhanced reputations among key stakeholders. AIRPORT FLIES GREEN In August 2001, Delta Air Lines reached an agreement with the Massachusetts Port Authority (Massport) to redevelop Terminal A at Boston Logan International Airport—New England’s largest airport. As an added feature to redeveloping the terminal, Massport was to transform the 686,000 sq ft into the ﬁrst truly sustainable structure of its kind and to achieve a USGBC LEED rating. “As we ﬁnalized our investigations of what would be required to complete this major project, it became apparent that our power systems would need state-of-the-art solutions,” said John MacDonald, PE, senior electrical engineer for the project, TMP Consulting Engineers, Boston. “We turned to Eaton’s Electrical Group because of its reputation in the electrical industry.” Because of the length of the buildings (the Satellite Building was 1,100 ft long), the buildings were split in half electrically, with a doubleended substation using cast-coil transformers to serve each half. Eaton’s Electrical Group offered a solution that would not only provide Massport lighting controls, but also measure the airport’s energy usage and ultimately reduce energy consumption. Eaton provided Massport with its Pow-R-Command 100. This system controls individual loads, and switches them through a network of individual panels. These are inﬂuenced by BAS, wall switches, time schedules, and software, and through telephone commands. FLEXIBLE CONVENIENCE The KOHLER® MPAC™ 1500 Transfer Switch By scheduling the lights to turn off when the terminal is not in use and using daylight-harvesting controls, the network system reduces light energy consumption at the terminal by as much as 30%. As a result of Eaton’s energy control system, Terminal A at Boston Logan Airport met the Massachusetts Energy Code, which mandates that lighting controls be used on all buildings to ensure lights are scheduled off at night and lighting is off in unoccupied rooms. A GREEN EDUCATION Eaton and the University of Notre Dame, South Bend, Ind., have had a long-standing relationship. Based on this relationship and past collaborations, it was a natural progression for the university to discuss projects with Eaton and explore how the two organizations could work together to solve the university’s energy-related challenges. This particular challenge: to start and control a 1,750 hp fan motor for a large-scale wind tunnel for the Aerospace and Mechanical Engineering Dept. of the College of Engineering. Planning began in 2006, orders started in 2007, and installation began in early 2008. Because this installation is part of a major research project, the concern was the ability to start and control such a large load without adversely impacting the university’s electrical distribution system, and providing the researchers with the ability to control the experiment at various speeds. Eaton provided its medium voltage drive that instructs the motor to start and operate at variable speeds and loads without stressing the university’s electrical distribution system, while also minimizing motor wear and tear. By also using Eaton PowerNet controls, the university Utilities Dept. has been able to manage the operation of this signiﬁcant load to avoid undesirable power demands and associated penalty costs. ■ Flexible “plug and play” design allows for future power system adaptations.
