The Portola Valley Town Center demonstrates to the community the towns leadership role in sustainability design. The extensive use of natural ventilation, daylighting and shading, plus the use of recycled and reclaimed materials give the three buildings a comfortable and natural feeling while accomplishing energy conservation. The site was carefully designed with sensitivity to stormwater management and the preservation of old growth redwood trees. Their application for LEED certification shows qualification for a Platinum rating and the photovoltaic cells on the roof demonstrate a commitment to trying new technologies to reduce carbon footprint.
