The new classroom building draws from a palette of materials that were
already established through recent work done at the high school. The
main roof form for the building is a shed roof, which slopes from east
to west. The high point of the shed roof faces the taller massing of the
gymnasium on the west side. The low side of the shed relates to the
massing of smaller, multifamily residential units on the east side.
Brick constitutes the main body. Just above the brick, the wall plane
steps back two feet in order to create a clear distinction between roof
plane and the brick wall.
Each point of entry is highlighted by a change in form and material. The
north and south entries are composed of louvered steel and glass boxes.
At the east and west entries there are towers which use a combination of
corrugated metal and extruded rectangular forms. The towers serve as
elements, which provide a visual break to the 241-foot long brick
The building uses a wide range of sustainable materials and techniques
and was designed to meet LEED® Silver criteria. Concrete floors are used
instead of the traditional VCT flooring. Both steel louvers and
sunscreens are used as a means to control building heat gain. The
sunscreens, composed of steel grating and steel outriggers, are placed
directly above the windows at all classroom locations. Each classroom
also has operable windows which allow for air circulation and for
passive cooling to occur. The steel louvers are used to screen large
expanses of glazing found at the north, south, and west entrance towers.
The east and west towers also have north facing clerestories which pull
in additional light to the lobby spaces below.
