Conclusion At first glance, one may be surprised to find that at $54,070 Anderson Hall's total cost of utilities was nearly two percent lower than Rinker Hall's $54,975 for the year 2004. However, several key determining factors must be taken into account in order to accurately qualify the numbers presented figure 4-13. First is total building horsepower. The two structures are within three percent of one another in total building square footage, while the building horsepower for Rinker Hall is double that of Anderson Hall. Similar to the above comparison with Frazier Hall, these results show that Rinker hall performs considerably more efficiently based on horsepower levels than does Anderson Hall. Second is total classroom area and student traffic. Anderson Hall houses eight general purpose classrooms, while Rinker Hall contains six classrooms, six student laboratories, and one large auditorium. As noted above, Rinker Hall operates from 6:30am until 11:00pm, on weekdays while Anderson is operational 7:00am until 8:00pm. Both buildings are operational for four hours per day on weekends and holidays. Therefore, Anderson Hall's 73 hours of operation per week is nearly 25 percent lower than Rinker's 90.5 hours and should more than offset the two percent difference in annual utilities between the two buildings. One should also note that during the harsh Florida summer months of June-September, Rinker Hall ran more efficiently than Anderson despite the extensively larger systems at work within the structure. Summary Analysis The above data for each comparison was consolidated into "total energy values" and is presented in table 4-23
