It does not include fuel used by the Town of Hillsborough, or outside agencies (AEC, Orange Enterprises, etc.) (1) Animal Shelter vehicles fuel use was not captw•ed vl previous periods, but is shown vi the August 2006 fuel figures. (2) Central Services no longer provides mail/courier service (3) Use of diesel fuel by OPT began with diesel vehicle on new Chapel Hill route in January 2006 (4) E1L1 S reduced gasoline usage, but increased diesel usage due to replacemeiu of older gasoline powered aanbulances with newer, diesel powered models. (5) Uses estunates of fuel usage by EIv1 S from the Town of Chapel Hill for July of 2005.

This model is used to effectively "remove" or adjust for the effect of outside air temperatures (Heating Degree Days (HDD) and Cooling Degree Days (GDD)) on energy use in Gounty buildings. "Actual" usage presents the number of kilowatt hours used during the most recent month as well as usage for the calendar year to date. "Baseline Projection" is a projection of the quantity of electricity that would have been used, adjusted for HDD and CDD, based on usage in the two-year baseline period. The "Difference," if a negative value, demonstrates that less energy was used than projected, resulting in a savings. If a positive value, the "Difference" indicates that more energy was used than projected. In order to allow appropriate "apples-to-apples" comparisons to direct changes in usage, outside lighting has not been included, as accounts are often rolled up for several buildings (i.e., outside lighting for the Government Services Annex includes not only the Annex but also Government Services Center, the Sheriff Department and the New Courthouse). "NOTE: due to utility billing cycles and dates, the most current complete information for natural gas and electricity usage is for the month of August 2006.
