A proposed re-lamping project includes 200, 2 lamp fixtures. The existing lamps are standard 40 W fluorescent bulbs with a lifespan of 20,000 hours that cost $1.25 each. The proposed replacement lamps would be high efficiency devices that give the same light output for only 34 W input with a life of 22,000 hours. These lamps cost $2.50 each. The fixtures are on 250 days for 12 hours a day during a year. Electricity costs are 0.12 $/kWh and 180 $/kW-year for energy and demand respectively.

a)Compute the annual energy savings (kWh)

b) compute the power demand reduction in kW per year

Exercise 2: A new IS project has been proposed that is expected to produce not only cost savings but also an increase in revenue. The initial capital cost to establish the system is estimated to be $500,000. The remaining cash flow data is presented in Table 2.10. Using a spreadsheet program, calculate the payback period, internal rate of return, and net present value for this project. Assume that the cost of capital is 7% and the effective tax rate is...
