SF Federal San Francisco Federal Building SF Federal San Francisco Federal Building Presentation Transcript

  • EnvS 132 Eric T. Lee San Francisco Federal Building // Green Building Presentation
    • AGENDA:
    • Location
    • Background
    • Architecture/ Design
    • Green features
    • LEED
    • Photos
  • LOCATION: 90 7 th St @ Mission (SoMa)
    • BACKGROUND:
    • Integrated custom window wall to regulate internal comfort via:
          • Natural ventilation
          • Thermal mass storage
          • Passive and active shading
    • BACKGROUND:
    • 1 st naturally ventilated West Coast office building since AC
    • Far more pleasant place to work than today's sealed-up, tinted- glass buildings pumped full of re-circulated, refrigerated air
    • Happier workers more productive
    • ;)
    • BACKGROUND:
    • 605,000 square feet
    • 18 stories; ~234’ high; 60’ deep
    • 2,700 employees
    • Approved Oct 14, 1997
    • Opened Feb 2007
    • Former Greyhound bus terminal
    • $125 million budget
    • BACKGROUND:
    • Houses 6 federal agencies:
        • BLS
        • DOL/ OSHA
        • GSA
        • HHS
        • SSA
        • USDA
    • BACKGROUND:
    • Managed by U.S. General Services Administration (GSA)
    • GSA manages ~ $500b in assets
        • 8,600 buildings
        • 205,000 vehicles
        • 425 historic properties
        • USA.gov
    • DESIGN:
    • Thom Mayne (Santa Monica)
    • Morphosis joined by Smith Group SF office as exec. Architect
    • FEATURES:
    • ~154k sq feet of 3’ x 8’stainless- steel panels (appear translucent) supported in front of all-glass wall on tube-steel frame
    • Concrete building frame
    • Shades building from low winter sun, cutting daylight to comfortable level for workers
    • FEATURES:
    • Concrete building frame
    • Large amounts of concrete are essential to facilitate a natural ventilation and cooling approach that takes advantage of thermal mass
    • FEATURES:
    • Unique concrete mix lowers lighting costs: 50% slag cement mixed with portland cement lightens the concrete color greatly increasing reflectivity throughout structure
    • FEATURES:
    • Airflow analysis
    • Window geometry
    • Panels designed to retain solar heat as thermal blanket over the building's facade
    • When air warms, it floats upward, coaxing cooler air through the building via windows that open automatically w/ sensors (free AC)
    • FEATURES:
    • Designed to consume about half the power of standard office tower -indication of how design can help slash emissions of greenhouse gases (electricity, etc).
  • FEATURES: North side has own sunshade system; vertical milky-glass fins angled to protect occupants from late-afternoon summer sun
    • FEATURES:
    • Most work using daylight from floor-to- ceiling glass instead of electric lights
    • Even an employee in ‘worst’ seat is only about 25’ from a window
    • LEED CERTIFICATION:
    • Applied for LEED Gold certification
    • Expected to receive Silver
    • LEED CERTIFICATION: GOOD FOR PLANET/ GOOD FOR BUSINESS:
        • Leading transformation of the built environment; built as designed, perform as expected
        • Lower operating costs
        • Increased asset value
        • Healthy and comfortable
        • Reduces waste sent to landfills
    • LEED CERTIFICATION:
    • Conserve energy and water
    • Reduce ghg emissions
    • Qualify for tax rebates, zoning allowances, and other incentives
    • Demonstrate owner's commitment to environmental concern and social responsibility
