Abstract: In the United States, the built environment accounts for nearly 40% of annual energy consumption and nearly 93% of total energy consumption is from non-renewable resources. In an effort to combat the depletion of natural resources and the pollution of Earth?s atmosphere, many buildings are being built using the sustainable guidelines set forth by LEED, or Leadership in Energy and Environmental Design. Research has suggested that while a LEED-certified building will, on average, perform at a more energy efficient level than a non-LEED-certified building, some LEED buildings are performing at much higher and lower levels. Up until only recently, there has not been a method in place which evaluates the actual energy efficiency of sustainable buildings. The intent of this study is to compare the energy efficiency of LEED to non-LEED buildings and to their energy models. Using Rinker Hall, a LEED-Gold certified building, and Gerson Hall, a non-LEED building, comparisons were made between each building?s annual and monthly energy consumption during 2005 and 2006. In this comparison, it was found that Rinker Hall consumed an average of 25% less energy than Gerson Hall. A subsequent comparison examined the differences between the actual energy consumption of Rinker Hall and the simulated energy consumption as presented by the energy model which was submitted during the LEED certification process. It was found that between 2005 and 2006, Rinker Hall consumed an average of 33% more energy than simulated by the energy model, but still consumed 21.5% less energy than the base case building presented in the energy model. This increase in consumption is thought to be a direct result of increased building usage. This research concluded that Rinker Hall, a LEED-Gold certified building, consumed 25% less energy than a comparable, non-LEED certified building. It is suggested the further research be conducted which closely examines energy consumption over a period of 5 years, as specified by LEED v3.0 and that a careful study of building occupancy be performed.

Design Analysis Study 28 Feb 2003 Riuker Hall, University of Florida LEEDTM Savings Margin Calculation The savings margins reported in Tables 4.2 and 4.3, and in Appendix D are relative to minim um compliance with ASHRAE 90.1-199, and include all connected power. For the purposes ofLEED certification, the savings are to be reported only for the "regulated" loads. According to LEED, "unregulated" loads include all process loads and "plug" loads. The logic ofthis is that building design decisions are not likely to address the level ofinternal load necessary to conduct the business of the enterprise occupying the building. Accordingly, the process loads are to be excluded from the calculation to deter mine the LEED/90.1-1999 compliance margin. Table 4.6 below summarizes the calculations to determine the 56% savings reported for LEED certification.
