In 2007, Matarozzi Pelsinger Builders worked out of a loft-like industrial space in the Mission that lacked sufficient air flow on the handful of warm San Francisco days.  During those San Francisco “heat waves,” we had to haul out 6’ tall industrial fans in a feeble attempt to move the air. With the fans howling, it felt like working in an old airplane hangar with prop planes readying to taxi out to the runway.

A few years later Matarozzi Pelsinger teamed up with architects Aidlin Darling to design and build their new space on 11th Street in the SOMA district of San Francisco.   The team transformed the 14,000 square foot building, originally the distribution warehouse for the Jackson Brewing Company in the early 1910’s, into a passively cooled LEED Gold Certified building housing offices and a restaurant.  Because the building is on the National Register of Historical Places, the City’s planning department required that the new building maintain the historical integrity of the corrugated façade.  In order to gain natural light and incorporate operable windows to the east and west, the building was clad with a new perforated zinc skin.   The corrugated zinc is perforated with holes ranging from 1/16” to 1” in diameter which allow light and air to pass through new aluminum windows hidden behind it.  This perforated siding does double duty as a shield for solar heat gain and as a breathable skin that enables cross-ventilation of the interior spaces.  Because the zinc skin is set in front of the windows, a pocket of tempered air is allowed to circulate inside.

The same double-skin passive cooling principal was used in the SF Federal Building.  That structure uses a building automation system to control the operation of windows above the 5th floor to allow the building to breathe through a perforated metal skin. Read more here.

San Francisco City College also incorporated a passive cooling system that uses a wind powered louver system in a central atrium and skylights in their newly completed Joint Use Academic Facility. Read more here.

As an added benefit, the Matarozzi Pelsinger Building’s zinc skin inadvertently complies with the new bird safety standards that were approved in San Francisco in 2011.  Read them here.
