This project connects the international Terminal E and domestic terminal C to allow easier passenger connections at Boston Logan International Airport. In addition, the adjacent waiting areas and facilities were upgraded and modernized. WSP was responsible for all lighting design on this primarily interior project.
The curved geometry of the existing building required a custom metal panel ceiling with recessed light fixtures carefully integrated for a seamless look. Rows of fixtures were staggered to provide even spacing and to complement the radial geometry without endless runs of fixtures.
The design team selected 3000K CCT for consistency across all fixtures and to create a comfortable, warm, welcoming feel. The design provides 21 fc ambient lighting in the seating areas, exceeding the IES Handbook recommendation of 15 fc. Additional fixtures at work counters add 9 fc of task lighting as well as visual interest.
Near the gates is a seating area that uses curved linear lighting fixtures to center the long curvilinear space. At one end of the connector is the large oval rotunda with skylight, providing a dynamic space as passengers enter or leave. The skylight is angled to the northeast, bringing daylight into the interior of the terminal while avoiding direct sunlight.
Three levels of cove lighting provide comfortable ambient lighting and highlight the soaring architecture and graphics of the rotunda. Over 250 individual adjustable fixtures in the upper two coves were aimed in a night focus before the scaffolding was removed.
Overall power density was 0.53 W/sf, 32 percent below the ASHRAE/IES 90.1 2010 code requirement. The lighting is tied into an existing control system which reduces light levels during times of low occupancy. At the client’s request, LED fixtures were specified for long life, low maintenance, and reduced energy use. The design provides an attractive, comfortable connection for passengers at the airport.
