20. 208V vs. 480V & 208V Distribution System Analysis Purpose  Analysis of alternative power distribution system based on first cost and efficiency  In conjunction with the Construction Management Breadth Existing System  (2) transformers, 2500 kVA-480V Multifunction floors, 1000 kVA-208V Residential Redesigned System  (1) 3750 kVA-208V Transformer Analysis Method  Reconfiguration and resizing of electrical equipment and system paths  Relocation of equipment (not included)  Cost analysis

21. 208V Single-Line Diagram

22.  RS Means 2003 Electrical Cost Data (materials & labor)  Location Factor: Rochester, Minnesota  Time Adjustment: 2002 Design Conclusions  Efficiency, Maintenance, and safety paralleled  First-cost basis ~ Maintain existing power distribution, 480V & 208V Distribution System Cost Analysis 37% Increase for Redesign

23. Existing Condition Daylighting Analysis E bv = M bv /2 = (E 1/2 kv * ρ b )/2 E 1/2 kv Conclusion  Decrease glass area decrease load  Minimal light loss Goals  Increase skywell efficiency  Decrease glass area  Allow dimming
