| Site Selection |
- Made use of an existing 1957 office complex owned by Southern
California Gas Company |
|
| Campus vs. High-Rise |
- 44,572sf single structure |

| Disturbance of site throughout construction |
- environmentally sound construction methods for site demolition, excavation,
managing, recycling & disposing of waste |
|
| Construction Waste Management |

35%-60% |
|
| Superwindows |
- Low "e" high performance glazing reduces heat gain, windows are gas filled
and dual-glazed with a "heat mirror" sheet |
|
| South Facing Glass |
-former building's orientation limited solar benefits, but second story optimizes
natural light |
|
| Skylights & Clerestories |
-3 skylights (So-Luminaire Active Daylighting Systems) in the main first floor
corridor eliminates the use of over 6 million watt-hours of electric lighting, -Kalwall
Translucent Clerestory window walls sections are placed to allow natural daylight into
interior |
|
| Courtyards & Atria |

Insulation / Energy Efficiency |
|
|
| High Insulation |
- exterior walls combine foil-backed fiberglass batt insulation w/non-CFC, rigid foam
insulation to provide an R-value of 11, -roof insulation has an R-value of 38 |
|
| Low Emission |
- non-CFC |
|
| Recyclable & Natural Materials |
- predominantly concrete enhanced with batt insulation |
