  5. Existing Conditions • Building Envelope • 3-story • Brick Façade and aluminum panels to match surrounding buildings • Large curtain windows on east and south side of building South-East View Outreach Innovation Building Spring 2005

  6. Existing Conditions • Lighting/Electrical • Radial System with 15kV service cable into a 12.47kV-480Y/277V transformer • 2400A, 3-phase, 4-wire main switchboard • 100kVA emergency generator • UPS for loads that require uninterruptible power • Fire Protection • Wet-pipe automatic system • Dry-pipe system within server and video archive area Outreach Innovation Building Spring 2005

  7. Existing Conditions • Mechanical • Design Conditions • Summer 89F DB, 72F WB • Winter 5FDB • 6-Air Handling Units • Cooling coils range from 24.2 to 81.2 tons • 10,000 to 35,000 cfm • Perimeter 2-Pipe Fan Coil Units • 2-175 ton rooftop chillers and 1-54 ton chiller • UFAD and Ducted Systems Outreach Innovation Building Spring 2005

  8. Redesign Goals • Reduce Energy Use • Save money • Proper Indoor Air Quality South View Outreach Innovation Building Spring 2005

  9. Mechanical Redesign • Dedicated Outdoor Air System Overview • Independent unit to supply minimum OA for ventilation • Parallel system to meet remaining load • DOAS Benefits • Exact ventilation • Reduced OA loads • Lower Operating Cost South-West View Outreach Innovation Building Spring 2005

  10. Mechanical Redesign • New Mechanical System • Single chilled water AHU for ventilation • 11,500 cfm 77 tons cooling • 2-Pipe Fan Coil Units as parallel system • Some equipped with electrical heat for transition between seasons • Original AHU that supplies Server room to remain Outreach Innovation Building Spring 2005

  11. Mechanical Redesign • Enthalpy Wheel with DOAS • Reduced cooling coil load • Scroll Chiller • Original = 435 tons and 640 gpm • Redesign = 240 tons and 460 gpm • Reduction of 200 tons or 45% • 2-Air Cooled Chillers were selected to replace 2 larger existing air cooled chillers • Existing smaller chiller to remain • Used for Data Center AHU Outreach Innovation Building Spring 2005

  12. Mechanical Redesign • Pumps and Piping West View Outreach Innovation Building Spring 2005

  13. Mechanical Redesign • Underfloor Air Distribution System • Advantages • Flexible • Large amount of data cables • Disadvantages • Possible leakage • Requires a large volume of air • Supply air temperature Outreach Innovation Building Spring 2005

  14. Mechanical Redesign • Underfloor Air Distribution System with DOAS • VOA*TOA + VFC*TFC = VTOT*(65F) • (168)*(50F) + VFC*(70F) = (5194)*(65F) • VFC = 4706 cfm Outreach Innovation Building Spring 2005

  15. Mechanical Redesign • Emissions • Percent Reduction • NOx = 29% • SOx, CO2, and Particulates = 16% • Energy Charge • Electricity = $0.02383 / KWh • Natural Gas = $0.5 / therm • Energy Cost Savings • Savings of 692,632 KWh/Year = 16% reduction • $43,623 per year Outreach Innovation Building Spring 2005

  16. Mechanical Redesign • Cost Analysis • New Equipment Cost = $448,850 • Original Equipment Cost = $388,650 • Cost Difference for Redesign = $60,200 • Simple Payback Period = 1 year 5 months • Lost Rentable Space • Original Design = 7417 sq.ft. = 8.7% • Redesign = 4840 sq.ft. = 5% Outreach Innovation Building Spring 2005

  17. Electrical Analysis • Analyzed effects of Mechanical Redesign • Circuit Breaker Size • Conductor Size • Conduit Size New Primary Chilled Water Pump (Quantity 2) (2 HP, 480V, 3-Phase, P.F. = 0.90) NEC Table: 430-150 => FLC=2.7 A KVA= 1.73 * 2.7 A * 480V * 0.9 = 2.017 KVA Circuit Breaker Size: 2.7 A * 250% = 6.75 A => 20 A, 3 P Breaker Conductor Size: 2.7 A * 125% = 3.375 A NEC Table 310.16 => #12 THW (Cu) Conduit Size: NEC Table C1 => 1/2” Outreach Innovation Building Spring 2005

  18. Electrical Analysis Outreach Innovation Building Spring 2005

  19. Electrical Analysis • Panelboard Comparison • Original = 1000A • Redesign = 300A New Equipment Total kVA = Sum kVA + 25% * kVAmax = 175 Min Ampacity = Total kVA / (0.48kV * 1.73) = 210.75 Max Ampacity = (Sum kVA + 75% * kVAmax) / (0.48 kV * 1.73) = 260.86 Panel Ampacity = 300 A North-West View Outreach Innovation Building Spring 2005

  20. Fire Protection Analysis • Analyzed use of Clean Agent FP System • HFC-227ea chosen as agent • Suitable for use in normally occupied spaces • Design Concentration • 8-10.8% • Agent Hold Time > 10 minutes Outreach Innovation Building Spring 2005

  21. Fire Protection Analysis • Tank Size • 88.7 lbs. – 1600cu.ft. • 500 lbs. – 9000cu.ft. • 665 lbs – 12000cu.ft. • Floor mounted Tanks • 1” Piping Outreach Innovation Building Spring 2005

  22. Conclusions • DOAS with Fan Coils provide proper ventilation with reduced energy consumption • Yearly energy reduction of 16% • Cost savings of $43,623 per year • 1 year 5 month payback period • Electrical • Redesign of mechanical equipment reduced mechanical demand • Fire Protection • Clean Agent System using HFC-227ea should be used to protect valuable information and equipment Outreach Innovation Building Spring 2005
