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.
RECOMMENDATION(S): The Manager recommends that the Board authorize the Purchasing
Director to develop and execute a contract with Reece Noland & McElrath, Inc. in the amount of
$8,000, subject to final review by the County Attorney, that would produce identification and
development of appropriate energy-efficient HVAC replacement system options for the Orange
County Jail, and for identification of appropriate HVAC system modifications to rectify humidity
problems on the basement level of the Court Street Annex building.
