sitors. The ground level blocks contain a variety of retail, restaurant, and entertainment amenities that face the street and surround multi-story integrated parking garages at centers of the blocks. An undulating roof above reduces the apparent massing of the development.
More than 80 percent of the total site area is covered with this publicly-accessible green roof—a landscaped parkland with sports, recreational, and cultural programs—a significant new urban amenity for the city. The roof meets the ground along the western edge adjacent to the single story homes, providing privacy from development to the neighbors while allowing access directly from the street to recreational paths that follow the roof as it slopes above the buildings. The paths then span above the streets and connect the green roof sections overhead.
The sustainability goal for the Hills at Vallco is LEED Platinum. The monumental scale of the green roof will improve resource efficiency and mitigate climate change through its use of both captured storm water and recycled water. It will reduce the urban heat island effect, improve public health, minimize water run-off, improve water and air quality, improve energy efficiency of the buildings, and promote bio-diversity. In the long run, The Hills at Vallco ambitiously targets a Net-Zero Water policy. Water conservation efforts will include the extension of the Santa Clara recycled water line to The Hills at Vallco.

Curriculum studio / partecipanteRafael Vinoly Architects, founded in 1983 and based in New York City, is an internationally renowned architectural firm with projects spanning six continents. The practice’s key trademark is its ability to reinvent institutional typologies and integrate the public realm into civic buildings. The practice’s atelier design intelligence coupled with the capabilities of a large, multi-disciplinary firm produces appropriate, creative responses to program requirements.
We consider design an integrated field in which programming, function, implementation, engineering, economic feasibility, and cultural impact are not independent concerns or disciplines but elements which should be equally evaluated and addressed.
The uniquely diverse work the firm has completed includes award-winning museums, performing arts centers, convention centers, athletic facilities, hotels, hospitals, laboratories, recreational venues, residential complexes, and commercial, industrial, and educational facilities.
