This 16,100 square-foot classroom addition
to an existing school just north of San Francisco was designed
as a comfortable, open, day-lit facility, with excellent durability
and low maintenance. The program consists of nine new classrooms,
public space for lockers and social activities, and miscellaneous
support spaces. Sustainability was the prominent theme. Classrooms
have balanced daylighting supplied from two or more sides.
Direct and indirect pendant light fixtures provide excellent
light quality at low foot-candle levels. Light bulbs are low-mercury,
with high color rendition, and half the fixtures include dimming
ballasts and photosensors.
In lieu of air-conditioning, sloped roofs
have an integral radiant barrier and flat roofs have single-ply
white roofing both to reduce heat gain. Most windows are shaded
with overhangs, sunshades, or trees to control sunlight, and
window glazing reduces heat. Half of the classrooms have cross
ventilation with high clerestory windows to exhaust warm air.
The others have passive chimneys to exhaust warm air and provide
cross ventilation. To improve next-day comfort, ventilation
works at night to cool the building mass. Many sources of
indoor pollutants were reduced or eliminated.
Extensive native planting in the courtyard
includes a habitat garden designed to attract a variety of
insects and bird species and used in the education of the
students. The middle school students have enthusiastically
embraced the design and organized tours of the green building
features for their parents at the grand opening of their new
school.
