Assignment One Week One In class, we discussed the concept of the payback period. For this initial assignment, we will look at the payback time to recoup our investment in changing from existing fluorescent lamps to LED lamps. For this exercise, we will use KWH savings as the method of payback. We need to make a couple of assumptions: First, we will need to change the sockets and ballast on the strip fixture. Let's assume it takes a three-man crew to do the task, and they can accomplish four units per hour. The crew would be made up of a journeyman electrician, an apprentice electrician, and a general laborer. Assume that they are paid the prevailing wage. The second, they will need a power man lift. The delivery and pickup charge for a room size man lift is $250 and the daily rental is $100. Third, assume that electricity charges are currently 26 per kilowatt hour. There are four spaces on campus that we are proposing for this project. The following three classrooms: R. Requa; Cliff May; Harriet Winner; and finally, the main hall {Galleria?}.
