Question

Given an office building has three floors in it where the 1st floor consumes 12,000 watts for lighting, 2,000 watts for computers with a PF=.95, and 19,500 watts with a PF=.65 for a small concession type cafeteria. The second floor contains a mainframe computer center where all international business operations flow through. This floor consumes 85,500 watts of power with a PF=.72 which accounts for its own cooling equipment. The top floor is mostly office space and conference rooms and supports the HVAC equipment on the roof that services air and heat for the first and third floors. The third floor consumes approximately 28,000 watts for lighting, computers, and roof HVAC when the PF for this floor is 0.82. Determine the apparent power for the building.
