355 11th Street - Matarozzi/Pelsinger Building By Eric Bobrow
Location 355 11th Street, San Francisco, CA
Building Type Restaurant, Industrial, & Commercial office
Building Use • The contractors headquarters occupies the second floor, the third floor is used by an architecture firm, and the first floor and exterior courtyard is used as a restaurant and bar.
Type Of Project • Adaptive Reuse • An “in-kind” or “similar to what was there before” renovation of the exterior walls and a significant upgrade of the building’s original timber frame structure.
Architects Joshua Aidlin, Aidlin Darling Design
Dates • Awarded: LEED Gold • AIA San Francisco Chapter - Energy and Sustainability in 2009 • AIA/COTE Top Ten Green Projects in 2010 • AIA California Council in 2009 • Zerofootprint Re-Skinning Award in 2010
New exterior metal skin perforated with fields of small holes that allow light and air to pass through new operable windows hidden behind.
Permeable surfaces on over 85% of the available non-building site area, allowing storm water to drain directly to the water table rather than entering city sewers.
Unshaded roof areas have a 30kW photovoltaic array, providing 37,751-kWh of the building’s annual electricity
In-floor radiant heat is supplied by a high-efficiency condensing boiler rather than using gasoline or oil burners.
Daylight sensors automatically adjust the output of the main light fixtures to take full advantage of available sunlight
All adhesives, sealants, paints, coatings and carpeting used in the project were low-VOC per LEED-NC EQ Credits 4.1,4.2, and 4.3
Site Ecology • Over 20% of the site area, has been planted with drought-resistant plants that will require no irrigation after a 1-year establishment period. • The non-irrigated living roof filters storm water, insulates the building, and decreases the urban heat-island effect. • The project has applied permeable surfaces on over 85% of the available non-building site area, which allows storm water to drain directly to the water table part of the earth rather than entering the city sewers.
Site Ecology • Over 90% of all site surfaces are either planted or high-albedo, serving to lower surface temperatures • Minimum of six parking spaces, four of which have been reserved for alternative-fuel vehicles • Over 80% of the existing wall, floor, and roof areas of the original building were retained per LEED-NC MR Credit 1.1
Pervious surfaces—including landscaping, pervious pavers and drivable grass pavers—account for over 85% of the non-building site area.
Roof area not occupied by photovoltaics has been planted (xeriscape) and drains to the pervious site area. Precipitation managed on site is 57%
No gray water systems used Native Plants have been placed throughout the site, resulting in a landscape that will not require supplemental irrigation
Cost Implications • Secure bicycle parking and a shower room and locker area are available for the use of all building occupants, helping to make cycling to work a viable option—especially for those with longer commutes • Located in the heart of SoMa district so public transportation is used often • A custom conference room table and coffee table were designed for the primary office tenant and were re-sawn beams removed from the original building to make way for new exit stairs and elevator.
The building has been designed to be 100% naturally ventilated and passively cooled
On the east and west facades, the new metal skin is perforated with fields of small holes that allow light and air to pass through new operable windows hidden beyond.
The perforated outer skin provides light while mitigating solar heat gain and enabling cross-ventilation of the interior. This rudimentary double-skin façade becomes a screen for sunlight and air, allowing the stoic, industrial character of the original building to be maintained without the visual introduction of new fenestration.
