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

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

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”

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

34
Elevator Gen2™ with Remote Elevator Monitoring (REM ®)
Excavation depth: 47” (1,2 m) below finished slabTop height: 138” (3,5 m) above top slab– space for mechanical and emergency operationsDimensions: Door opening = 38” (900 mm ) 66” x 99” (1670 x 2520 mm) including construction tolerance
Costs: $50 000 (installation not included)

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

Energy demand
45
• 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
Reduce energy consumption
• Few large Air Handling Units
• Low speed
• Conformity regarding components
36
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

Geothermal Energy
Our site is not very suitable for geothermal energy

Other Green Concepts – LEED requirements
• 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
•Reusable materials•Recycling• Prefered use of bio-mass materials•Low VOC•Low contamination
