The 22-story Cecil and Ida Green Building (Building 54), designed by I.M. Pei and completed in 1964, is currently home to MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS) and the MIT-Woods Hole Oceanographic Institute (WHOI) Joint Program. An infrastructure renewal project is underway to enable the ongoing and long-term research needs of these programs by upgrading its building envelope and systems. A partner project (the new Earth and Environment Pavilion) to renovate the Green Building's primary lecture hall and expand programming is also currently underway.

In addition to the Building 54 envelope upgrade, project elements include replacing the roof, renewing the concrete façade, and updating bathrooms and other building interiors. The team is also working to modernize the elevators and carry out any code-required updates to ensure the building is accessible to the whole community. Major electrical and mechanical systems will be upgraded and optimized. The building's large radome has been replaced, and its rooftop equipment layout and support are being redesigned. Overall, the goal of the project is to improve occupant comfort and building performance.
