Palafox Street Pensacola, FL 32501 RE: NWFSC Community Services Complex Niceville, FL SCG Project No. 2006-226 Mr. Alsop, | have reviewed the electrical power demand for the Classroom/EOC portion of the Community Services Complex to determine an estimate of electrical power usage for the Classroom area versus the EOC area. | reviewed the scheduled connected load for both parts of the building - broken down into lighting, receptacles and mechanical equipment. These totals are as follows: Classroom Area a. Lighting load — 16.8 KW b. Receptacle load - 64.7 kW ¢.” Mechanical Equipment — 294.5 kW EQOC Area a. Lighting load — 37.6 KW b. Receptacle load — .280.9 kW ¢. Mechanical Equipment — 313.1 kW In order to determine an estimate of the power usage for each area, the hours of operation for each area must be considered. | estimated the lighting and receptacle loads for the Classroom area being used for 8 hrs/day. | estimated the mechanical equipment for the Classroom area being used for 12 hrs/day. The difference being the mechanical equipment cycling on and off during hours the Classroom area not being occupied. The lighting, receptacle and mechanical equipment loads for the EOC area are being used 24 hrs/day. By using these hours of operation the total kWhiday for each area can be estimated. These totals are as follows: Classroom Area a. Lighting load — 16.6 kW x 8 hrs/day = 132.8 kWh/day b. Receptacle load —64.7 kW x 8 hrs/day = 517.6 kWh/day - c. Mechanical Equipment — 294.5 kW x 12 hrs/day = 3,534 kWh/day Total = 4,184 kWh/day 40-S: PALAFOX PLACE, SUITE 360 PENSACOLA, FL-32502 P:850.438.0050 F:850.432.8631 www schmidtconsuliinggroup com ATACKMEUT 2 PAGE 2 OF 2 EQC Area a. Lighting load — 37.6 kW x 24 hrs/day = 902.4 kWh/day b. Receptacle ldad — 280.9 kW x 24 hrs/day = 6,741.6 kWWh/day ¢. Mechanical Equipment — 313.1 kW x 24 hrs/day = 7,514.4 kWh/day Total = 15,158.4 kWh/day Total estimate power usage/day — 4,184 kWhiday + 15,158.4 kWh/day = 19,342.4 kWh/day ' Classroom Area estimate usage/day — (4,184 kWh/day)/(19342.4 kWh/day) = 21.6% EOC Area estimate usage/day — (15,158.4 kWh/day)/(19342.4 kWh/day) = 78.4% Please let me know if you have any questions or need anything else.
