Engineering in Action
Construction is well underway on the Museum of Science’s Blue Wing renovation, which will culminate in a new space that enhances energy performance and provides unparalleled views of the city and the Charles River.
Incredible engineering has gone into this project to keep the Museum open while new beams were installed beneath the floor and lowered from above by crane — all while ensuring construction had no negative impact on the river. When the space opens, its thoughtful design will move the Museum closer to our ambitious sustainability goals.
An integral part of the design is a double-skin curtain wall system, a 25-foot mockup of which was erected behind the Museum to test and refine certain design elements (perhaps you noticed it outside the Yawkey Charles River Gallery during a recent visit?).

The system is a fascinating feat of engineering. Designed by our architects, engineers, and consultants, the interior and exterior walls of insulated glass are separated by a cavity that houses a perforated louver blind system. Together, these elements address the acoustic, temperature, and lighting needs of the new space. The exterior glass is also designed to be visible to birds, reducing the risk of bird strikes. In addition, vent systems adjust based on cavity temperature and help mitigate moisture.
The blinds between the exterior and interior glass are controlled by an astronomical clock and a brightness sensor. The clock determines when direct sunlight reaches each façade. On bright, sunny days, the system reduces heat gain and glare. Because each façade operates independently, stunning views can be maximized while still reducing demand on the Museum’s cooling systems.
The Blue Wing renovation is slated for completion in fall 2026, and we couldn’t be more excited. You can already experience some of the results of the project through the accessible restrooms — and new elevators are on the way!
