Studies have shown that hotels use 195 gallons of water per average overnight guest. This is nearly twice the rate of water use compared to the use per person in a home setting. Many hotels are located in areas that are naturally water stressed. Reducing the amount of water used per overnight guest is important for both environmental and economic reasons. For this assignment, you will calculate the costs associated with using conventional showerheads at the Xavier Hotel, and compare that to the costs of using low-flow showerheads instead. 1.All 450 of the guestrooms in the Xavier Hotel have six 75-watt incandescent lightbulbs. Each occupied guestroom uses the lights for six hours. With occupancy at 67%, how much does the Xavier Hotel spend per day on electricity to light its occupied guestrooms? Assume that electricity costs $0.18 per kWh. Follow these steps to work through this calculation: 2.The Xavier Hotel is considering replacing the six incandescent lightbulbs in each guestroom with six 12-watt LED lightbulbs. Each occupied gu
estroom would still use the lights for six hours, and the occupancy would still be 67%. How much would the Xavier Hotel spend per day on electricity to light its occupied guestrooms, if it switched to LED lightbulbs? Assume that electricity costs $0.18 per kWh. Follow these steps to work through this calculation: 3.How much does the Xavier Hotel spend per year on electricity to light its occupied guestrooms with incandescent lightbulbs? Follow these steps to work through this calculation: 4.How much would the Xavier Hotel spend per year on electricity to light its occupied guestrooms if it switched to LED lightbulbs? Follow these steps to work through this calculation: 5.How much electricity (in kWh) would the hotel save per year if it switched all of its guestrooms to LED lightbulbs? Follow these steps to work through this calculation: 6.How much money would the hotel save per year if it switched all of its guestrooms to LED lightbulbs? Assume that electricity costs $0.18 per kWh. Follow these steps to work through this calculation:
