7 ~. 70% cumulative fuel savings as measured by total fuel usage against the FY10 baseline by FY 15, and an additional 5% by FY 17. A summary of the County's trends in energy, water and fuel usage between FY05 and FY10~ are as follows. • Total energy usage as measured in millions of BTUs (MMBTU) per 1,000 square foot of occupied space2 in FY10 decreased by 0.8%, when compared to weather normalized figures for FY05 energy usage; • Total water usage per square foot of occupied space decreased significantly, reaching 16.5 gallons/ sq. ft. in FY 10, or 18% less than in FY 05; • Total fuel usage was only 1 % greater in FY 10 than in FY 05. The composition and occupancy of County buildings and facilities changed so significantly between FY 08 and FY 10, that going forward FY 10 would provide a much more suitable baseline for future comparisons. There have also been changes in the composition of the County's vehicle fleet, including the addition of more alternative fuel vehicles3. For these reasons, the ECT intends to report future fiscal years' usage compared to the FY 10 "baseline" usage. Most of the County's newest buildings, which are much more efficient than older buildings, have been online for less than two years. Going forward, energy use as measured by MMBTU/ 1,000 square feet will continue to decrease because of this efficiency. For example, comparing the following new buildings to Southern Human Services' energy use per sq. ft. finds • The Main Library uses 32% less energy • The West Campus Office Building uses 35% less energy • The Justice Facility uses 57 % less energy The ECT intends to report the County's energy use and progress on conservation on an annual basis. This is the inaugural report. Future reports will be presented as part of the annual budget process to allow appropriate consideration of items with financial implications. The existing Energy, Water and Fuel use policies (originally adopted by the Board of County Commissioners in December 2005, effective January 1, 2006) are included as Appendices B, C and D. 1 The Animal Services Center provides significantly different service then typical County buildings and has therefore been excluded from County-wide energy usage figures. 2 "Occupied" square footage is the actual portion of grosss space that is actually occupied at a given point in time. There were a variety of methods use in the calcuation of the occupied square footage figures. a Refers to alternatives to traditional vehicles powered by gasoline or diesel only. See Appendix 'A' for a more detailed explanation. 2
