project description

The Law School building provided the University of Washington with a facility to house their law school functions in one space. Programming includes classrooms, faculty offices, graduate program centers, student activities areas, library stack spaces, and mock court rooms. The building was named after William H. Gates, a distinguished former graduate of the U.W. Law School and father of Microsoft chairman Bill Gates. The building HVAC systems are served by a series of semi-custom air handling units located in the roof Penthouse. The building offers challenges to the HVAC system with its extensive use of glazing.
