2 community geo-thermal system with the exception of interior equipment at the Jail. This was proposed to allow replacement of this equipment following relocation of most inmates and staff from the existing Jail to the new Jail. A total of $1,709,200 remained in the 2012-17 CIP for fiscal year 2012-13, with $752,400 moved to year 2015-16. Approximately $372,000 of the $752,400 was estimated for replacement of existing HVAC equipment in the Jail, with the remainder being for new ventilation and exhaust systems, etc., as part of repurposing of existing Jail following occupancy of a new Jail. Replacement of the existing HVAC equipment as part of the current project rather than waiting until completion of the new Jail will save approximately $260,000. As such, AMS staff recommends completion of all aspects of the project, including interior equipment at the Jail at this time, due to both the timing of completion of the new Jail and the attractive pricing of the overall project based on the bid received from Warren-Hay Mechanical. Based on results from the existing geo-thermal installations currently serving the Justice Center and the Link Center, the replacement geo-thermal system is projected to save the County 30- 35% in energy costs annually with significantly lower maintenance costs and quieter, more environmentally sustainable operations. While the geothermal system's initial cost is approximately 10% higher than conventional systems, it will pay for this premium within 8 years of operation in saved energy costs. While no grant funding opportunities were identified as being available for this project, the project is eligible for a project funding rebate from Duke Energy under their "Smart $aver' Incentive Program. AMS and staff with RN&M are currently preparing the necessary applications for funding through this program. As the recommended location for installation of the geo-thermal well field includes areas around the Farmers' Market pavilion, AMS staff met with representatives from the Farmers' Market and the Sheriff to make arrangements for temporary relocation of the Saturday morning market to the parking area in front of the Sheriff's Department. This will assure uninterrupted operation and maintain visibility for market customers. AMS will also be coordinating with the Sheriff, District Attorney and court system staff to minimize impacts related to drilling operations and equipment change-outs during the project. The project timeline for completion of this project is as follows: TASK PROPOSED END BY START DATE DATE BOCC Action: Community Geo-thermal HVAC Phase II Bid 6/18/13 6/18/13 Award Well Field Installation (four month duration) 07/22/13 10/25/13 Equipment Installation four month duration 10/28/13 1 02/25/14 System commissioning, balancing, digital controls calibration, etc. 1 02/25/14 1 05/25/14 FINANCIAL IMPACT: A total of $1,793,700 is available as part of the HVAC Projects Capital Improvement Project fund related to the facilities included in the geo-thermal project (Jail, Courthouse, Court Street Annex and District Attorney building).
