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. 37% Increase for Redesign Distribution System Cost Analysis • 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

23. Ebv = Mbv/2 = (E1/2kv * ρb)/2 E1/2kv • Conclusion • Decrease glass area decrease load • Minimal light loss Daylighting Analysis Goals • Increase skywell efficiency • Decrease glass area • Allow dimming Existing Condition

24. Finalized Redesign Well ~ 40’ X 6’ Splay ~47’ X 14’

25. Hap Analysis Existing DesignRedesign Existing: 8.6 Tons Redesign: 7.4 Tons • Savings: 1.2 Tons or 86% of original • Energy Savings • No equipment resizing

26. Alternative Option • Direct switching • Payback~0.5 years Daylighting Analysis Pool Dimming Yearly Savings: $164.17 Dimming vs. Non-Dimming Equipment Cost Difference Time of Payback $400 2.5 years Skyway Dimming Yearly Savings: $246.35 Dimming vs. Non-Dimming Equipment Cost Difference Time of Payback $1820 7.4 years With (11pm-5am) Dimming Considered 5.3 years

27. Conclusions • Lighting Depth • Creates a “home away from home” welcoming atmosphere • Provides flexibility and easy control for users • Satisfies all goals and design criteria set forth Electrical Depth and CM Breadth • Alternative power distribution system viable • Selection of existing system based on first cost • Daylighting, Mechanical, and CM Breadth • Mechanical energy savings incurred • Electrical energy consumption decreased

31. Daylighting Analysis • Pool • Continuous dimming over pool • Skyway • Continuous dimming along corridor AGI 32 Software Study • Rochester, MN weather data • 3 Sky Conditions • (5) 2-hour intervals per day

32. HAP Analysis • Methodology • Proper U-value calculation of surfaces • Lighting Load: 1.0 W/sq.ft. • Occupancy ~ 10 people • Evaporation load of pool (2003 ASHRAE HVAC Applications) • wp = 0.1A(pw - pa)Fa = 2.499 lb/h • Btuh = wp * 45Btu/lb = 112.5 Btuh (latent load) • Where: • pa = saturation pressure at room air dew point • pw = saturation vapor pressure taken at surface water temperature • Fa = 0.65, Condominium Pool Water Temperature = 80 F • Dry Bulb Air Temperature = 78 F % Relative Humidity = 55
