HVAC Replacement Projects <br />Fiscal year 2003 -04 marks the first year that the CIP has included funding_ for HVAC <br />replacements. Many of the existing HVAC systems are aged and in need of repairs and <br />replacement. County staff has reviewed the age, condition and potential impact of failure of <br />heating, ventilation and air conditioning equipment serving County buildings and have identified <br />the following as important priorities for replacement during the 2003 -04 fiscal year. While there <br />remain other outstanding projects that are in need of replacement, the chart below outlines the <br />ones that staff deems as the most critical at this time. As part of the scope of work for the <br />HVAC system design, the design engineer will be required to investigate and report on <br />environmentally sound and energy efficient options <br />Recommended HVAC Replacement Projects for Fiscal Year 2003 -04 <br />BUILDING <br />COMPONENT <br />EST <br />NEED /DEFICIENCIES <br />COST <br />Courthouse <br />Air handier <br />$70,000 <br />The air handler that serves the large first floor <br />(New) <br />courtroom (Superior Court) is original to the building <br />(1954) and is well past its expected useful life. <br />Replacement is recommended before the need for a <br />more costly emergency replacement in the event of <br />equipment failure. <br />The existing equipment is located in the attic, and <br />was "built in" when the New Courthouse was <br />originally built. Removal of existing equipment will <br />require dismantling the unit for removal through attic <br />windows. Estimated replacement cost includes <br />installation of modular equipment, roof top units, or <br />"twinning" two small units to achieve the same <br />capacity. <br />Jail <br />Chiller <br />$80,000 <br />The chiller that serves the old Jail (pre -1997) is <br />approximately 21 years old, and as such is past the <br />expected useful life of 15 to 20 years. Due to the <br />age of the unit, replacement parts for repair are <br />becoming increasingly difficult to obtain. <br />This equipment serves a critical building that is <br />occupied 24 hours per day, 7 days per week. <br />Replacement is recommended before the need for a <br />more costly emergency replacement in the event of <br />equipment failure. <br />TOTAL <br />$150,000 <br />
