  10. 12

  11. Flying Box – 1st structural system - Floorplan - steel construction with pile foundation - concrete slab, use of composite beams N 13

  12. Flying Box – 1st structural system – Section A-A - perimeter MRF for lateral loads - use of base isolation to decrease lateral loads 14

  13. Flying Box – 2nd structural system - Floorplan - Cast in Place Concrete Construction 15

  22. Boxes in Forest – 1st Structural Concept - Reinforced concrete 29

  23. Boxes in Forest – 1st Structural Concept - Reinforced concrete 30

  24. Boxes in Forests – 2nd structural design – Second Floor Plan - Cloumns and beams layout - “Forests“ location need to be adjusted 33

  25. Boxes in Forests – 2nd structural design – Third Floor Plan - Customize the elements - Eccentric center of stiffness 34

  26. Boxes in Forest – Auditorium - candilevered auditorium - truss construction, pile foundation W 16x57 W 14x34 W 14x74 N W 14x34 36

  27. Boxes in Forest – Auditorium - Roof - cable construction to reduce the steel amount - bay size is 50 ft cable W 16x57 W 14x26 37

  28. Access for workers – before morning transit Site offices Recycling area Cranes Dry material storage Material storage Access for materials – least disturbing for on campus activities 38

  29. Structural System Cost Comparison – Concept 1 “Flying Box” Construction permit fee Total permit fee is $ 108 000 Fees included in the estimate: fire hydrant fee, sewer fee, arts development fees, LAUSD developer fees, dwelling unit tax and utility connection. 39

  30. Cooling Load Estimate • “Rule of Thumb”: 1 Ton/400 SF • Required Airflow: • Main Duct Run: 40” f for low pressure • Equivalent to 76”x19”, 60”x24”, 37”x37” • Horizontal Duct Run each floor: 28” f for low pressure • Equivalent to 29”x23”, 56”x14” 41

  31. Say 2’ for access 18” min 6’-9” 37” 37” 5’-3” 32’ Electrical Equipment Hot Water heater 22’ AHU: 9.6’ x 28’ x 6.01’high Mechanical shaft sizing Minimum area for mechanical shaft 6.75’x5.25’ = 35.5 SF Mechanical room sizing Plumbing Mech Room 32’x22’ = 704 SF 42

  32. HVAC System • Conventional System Option • Under-floor Passive Distribution System Option • Energy savings • Less ductwork • Easier maintenance 43

  33. Elevator Gen2™ with Remote Elevator Monitoring (REM ®) Low energy consumption Low speed Reduce need for maintenance by no switches, no gear-weel, no oil use. Only reusable components. Encourage usage of the stairs– fewer users –less mechanical wear Excavation depth:47” (1,2 m) below finished slab Top height: 138” (3,5 m) above top slab – space for mechanical and emergency operations Dimensions: Door opening = 38” (900 mm ) 66” x 99” (1670 x 2520 mm) including construction tolerance Costs: $50 000 (installation not included) 44

  34. Energy demand • Reduce energy consumption • Few large Air Handling Units • Low speed • Conformity regarding components • Energy Demand • 145 kBtu/SF for University Bldgs (1995 DOE Data)1,300,000 kWh/year • Peak Energy Demand • 9.33 W/SF (75th percentile 1995 DOE data) • With 4% annual growth: Total 2015 Peak Energy Demand = 500kW 45

  35. Geothermal Energy Solar Energy • Solar Supply = 12 W/SF • For 50% of roof area, max available solar energy = 180 kW, or 36% of estimated peak energy demand. • @ $6/W, 500 kW of solar energy installed = $3,000,000, 42,000 SF!! • @ $6/W, 180 kW of solar energy installed = $1,080,000 • $3/W Rebate (CA Energy Commission) • Total installed cost = $540,000 • Energy savings as high as $25,000/year Our site is not very suitable for geothermal energy Source: California Energy Commission “Preliminary Renewable Resource Assessment,” July 2003 46

  36. Other Green Concepts– LEED requirements • Reusable materials • Recycling • Prefered use of bio-mass materials • Low VOC • Low contamination • Green Roof • Cut cooling costs 20-30% • Stormwater, aesthetics, acoustics • Waste heat recovery • Thermal storage in building mass • Climate façade • IR reflective coatings/paint • Hybrid Solar Lighting • Low-flow plumbing fixtures • Grey-water recycling • Storm water control – native plant landscaping 47

  38. Green funding • Public Interest Energy Research Program (PIER)  California Energy Commission (solar energy) • Environmental Protection Agency (EPA) Drinking Water State Revolving Fund (green roofs) • Renewable Resources Trust Fund Emerging Renewables Program (solar energy) 48
