4 <br /> I . SPORTS LIGHTING - LIGHT=STRUCTURE GREEN TM SYSTEM <br /> A. BASE BID LIGHTING EQUIPMENT <br /> The primary goals of this sports lighting specification are: <br /> 1 . Life Cycle Costs: In order to reduce the operating budget, the preferred lighting system shall <br /> be energy efficient and cost effective to operate. All maintenance costs shall be eliminated , <br /> and the fields should be proactively monitored to detect fixture outages over a 25 year life <br /> cycle. To allow for optimized use of labor resources and avoid unneeded operation of the <br /> facility, customer requires a remote on/off control system for the lighting system . <br /> 2 . Environmental Light Control : It is the primary goal of this project to minimize spill light and <br /> glare. <br /> 3 . Guaranteed Light Levels: Selection of appropriate light levels impact the safety of the players <br /> and the enjoyment of spectators. Therefore the lighting system shall be designed such that the <br /> light levels are guaranteed for a period of 25 years . <br /> B. LIGHTING PERFORMANCE if PLAYABILITY <br /> The manufacturer shall supply lighting equipment to meet the following performance and life <br /> cycle cost criteria: <br /> 1 . Playing surfaces shall be lit to an average constant light level and uniformity as specified per <br /> the bid sheet. Light levels shall be held constant for 5000 hours . Lighting calculations shall be <br /> developed and field measurements taken on the grid spacing with the minimum number of grid <br /> points specified on the bid sheet. Measured average illumination level shall be +/- 10% of <br /> predicted mean in accordance with IESNA RP-6-01 , and measured at the first 100 hours of <br /> operation . <br /> 2 . Manufacturer shall provide computer models guaranteeing light levels on the field for 25 years <br /> with a recoverable light loss factor of .7 in all applications . <br /> C. LIFE CYCLE COST <br /> 1 . Energy Consumption : The kWh consumption for the field lighting system shall be calculated by <br /> the following criteria : <br /> # luminaries x kw demand x kw rate of .22/hr x annual usage of 400 hours x 25 years . <br /> 2. Complete Lamp Replacement: Manufacturer shall include the appropriate number of group <br /> lamp replacements to be completed at end of each 5000 hours of operation . For the purpose <br /> of the bid, it is assumed that the field (s) will be operated 400 hours per year or 10,000 hours <br /> during a 25 year period. Manufacturer shall warrant the system to meet designed light levels <br /> upon completion of these relamps. <br /> 3. Preventative and Soot Maintenance: Manufacturer shall provide all preventative and spot <br /> maintenance, including parts and labor for 25 years on the system from the date of equipment <br /> delivery. Lamp outages shall be repaired when they materially impact the usage of any field . <br /> Owner agrees to check fuses and maintain as necessary in the event of a fixture outage prior to <br /> calling the manufacturer. <br /> 4 . Remote Monitoring System : System shall monitor lighting performance and notify manufacturer <br /> if individual luminaire outage is detected so that appropriate maintenance can be scheduled . <br /> The manufacturer shall notify the owner of outages within 24 hours , or the next business day. <br /> The controller shall determine switch position (Manual or Auto) and contactor status (open or <br /> closed ) . <br /> Jacksonville Spec 04-24r5.doc 6 Created on 12/1/2006 4:32 PM <br />
