ORANGE COUNTY BOARD OF COMMISSIONERS ACTION AGENDA ITEM ABSTRACT Meeting Date: August 22, 2006 Action Agenda Item No, 5- x SUBJECT: Jail HVAC System Replacement Analysis DEPARTMENT: Purchasing/Public Works PUBLIC HEARING: (Y/N) No ATTACHMENT(S): None INFORMATION CONTACT; Pam Jones 919-245-2652 Wilbert McAdoo 919-245-2625 Wayne Fenton 919-245-2628 PURPOSE: To consider authorizing a contract for professional services with Reece, Noland & McElrath, Inc. for preparation of an analysis of heating, ventilation and air conditioning (HVAC) system needs for the Orange County Jail (pre-1997 sectors), and identification of an appropriate energy-efficient replacement system; and to provide recommendations for addressing humidity concerns for the basement level of the Court Street Annex building. BACKGROUND: The chiller serving the pre-1997 sections of the Orange County Jail is approximately 25 years old, and as such is becoming increasingly unreliable for meeting the on-going demands of this 24 hour per day, 365 day per year facility. In addition, due to growth in the number of occupants (staff and inmates) and modern standards for ventilation, the overall HVAC system is in need of replacement. Staff proposes retaining the services of Reese, Noland & McElrath (RNM) to identify current heating and coaling loads for the Jail and to identify an appropriate energy-efficient replacement HVAC system, including improvements needed to bring the system to current standards for air flow/ventilation. The cost of this work will be $6,800.00. A key early outcome would be identification of the appropriate capacity for a new chiller so that, in the event of chiller failure prior to replacement of the entire system, an appropriately sized chiller could be specified and installed,. As part of its assessment, RNM will be asked to evaluate non-traditional solutions (e.g. geothermal) and to include noise abatement considerations in its recommendations. In addition, the Court Street Annex building has experienced on-going concerns with humidity on the basement level. Reece Noland & McElrath would provide recommendations for HVAC system improvements to rectify these conditions, at a cost of $1,200. FINANCIAL IMPACT: The County's Assessments and Studies Capital Project Fund includes sufficient funds to pay for the analysis ($8,000). The analysis will offer HVAC system replacement cost estimates that staff can incorporate into future years long range capital plans.
