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

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)

44

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
