Kroon Hall has unified the dispersed faculty buildings across Science Hill by becoming a focus for this micro-campus. A strong architectural identity has been established for the faculty, which forms a centre for the study of sustainability. The building has been awarded LEED ‘Platinum’ certification by the US Green Building Council.

The structure accommodates offices for the faculty, classrooms, a library and study centre, an auditorium, and the Environment Centre: a flexible space which will host exhibitions and symposia.

The building is a four-storey rectangular volume with a steep pitched roof. It is constructed from a combination of natural and contemporary materials: stone, timber, concrete, steel and glass.

Kroon Hall sits between the neo-gothic Osbourn Memorial Laboratory and Sage Bowers Hall, sub-dividing the interstitial space to create two new courtyards, and reintroducing the Yale collegiate urban structure. The north side of the building is buried into the sloping site, allowing access on the two lower floors, as well as making connections, knitting together the separate buildings of the faculty. The west elevation boldly announces its presence on Prospect Street, and in contrast, the east elevation opens out onto the historic Sachem's Wood.

Hopkins Architects worked with Centrebrook Architects as Executive Architect, Arup as Structural & Service Engineers, Judith Nitsch Engineering as Civil Engineers, Olin Partnership as Landscape Architect, Faithful+Gould as Quantity Surveyors, P.R. Shermann as Code Consultant, Atelier Ten as Sustainability and LEED Consultant, and Turner Construction as Main Contractor on this project.
