The Kimbell Museum of Art’s Piano Pavilion is designed to accommodate the museum’s growing exhibition and education programs. Built by Beck, the new building provides gallery space for temporary exhibitions, classrooms and studios, 299-seat auditorium, expanded library, and underground parking. The expansion roughly doubles the museum’s gallery space. Featuring an airy, transparent façade, the astoundingly smooth and uniform architectural concrete walls beg to be touched. A series of aluminum louvers on the roof move to shade direct sunlight and diffuse sunlight. The louvers are just one of several green features that will make energy consumption in the new building nearly half that of the old.
