The King Open and Cambridge Street Upper School and Community Complex is a big enough deal to warrant its big name.

With net-zero-carbon operations and LEED v4 Platinum certification, the 273,000 ft² project includes multiple schools, a public pool, a public library, lots of open space for the entire community to use, and a variety of social services for families.

Students have access to rain gardens and bioswale bridges, digital dashboards showing energy use patterns, and an exposed purple-pipe system. The building uses 43% less energy than a typical Massachusetts school and 70% less than the average school in the United States, according to Arrowstreet, the architecture and design firm.

The project earned 83 points under the Building Design and Construction–Schools rating system and was certified in February of 2021.
