The Thayer School's tradition of balancing research with teaching will be maintained and enhanced in this new mixed-use facility through the addition of the following spaces:

  • 8 undergraduate student project work areas
  • 2 smart classrooms
  • 3 conference/study rooms
  • 5 studio labs, which will help to integrate information technology more effectively into teaching
  • 8 additional faculty offices
  • 2 research labs designed to ensure casual interaction between students and faculty

The exterior focal point of the new building is the new entry courtyard for the Thayer School complex. A 3-story atrium with a granite floor ties the new building to Cummings Hall and provides an interior pathway with windows into both student laboratory spaces and project display cases. This visibility of the lab spaces continues throughout the building, providing the opportunity for the process of engineering to be revealed.

MacLean ESC was designed and built with a focus on energy conservation, with the goal of receiving U.S. Green Building Council LEED Silver certification utilizing:

  • High-performance building envelope featuring spray-foam insulation and triple-glazed windows
  • High-volume variable-speed cooling and ventilation system with enthalpy wheel energy recovery
  • Radiant floor heating in the 40-foot tall atrium
