8.A. - Page 117 <br /> Exhibit B. Engineering and Construction Requirements <br /> • Installation of shade structure PV systems in all locations shall include the installation of <br /> new high efficiency lighting. Installation of shade structure PV systems shall include the <br /> removal of existing security light poles, foundations, and fixtures that are no longer <br /> effective. <br /> • Lighting shall be LED lighting or other similar energy efficient lighting system. <br /> • New parking lot fixtures shall be installed to provide parking lot illumination compliant <br /> with IESNA requirements or recommendations for illumination and safety. <br /> • Minimum horizontal illuminance of one (1) foot-candle shall be maintained at ground <br /> level with a uniformity ratio (maximum to minimum) of 15:1. <br /> • The new lighting is required to illuminate the entire parking area and adjacent pedestrian <br /> walkways affected by the removal of existing lights to restore light levels to similar <br /> condition as before, not just the area under the PV modules. <br /> • A photometric illumination plot must be submitted for each parking lot showing all <br /> existing lighting and proposed new SSS canopy lighting. <br /> • Submit California Title 24 Outdoor Lighting calculations with all lighting drawings and <br /> show evidence of compliance. <br /> Photocell controls shall be used in conjunction with a lighting control system for all exterior <br /> lighting and energize lighting when ambient lighting levels fall below two (2) foot-candles <br /> measured horizontally at ground level. Lighting shall also be required to operate manually <br /> without regards to photocell input. Replacement parking lot lighting shall be served from an <br /> existing parking lot lighting circuit and any existing circuits and existing control function shall be <br /> maintained, or if replaced, done so at the approval of the Buyer. <br /> 3.5.19 Monitoring System, DAS,and Reporting <br /> Seller shall design, build, activate and ensure proper functioning of Data Acquisition Systems <br /> (DAS) that enable the Buyer to track the performance of the PV Systems as well as environmental <br /> conditions through an online web-enabled graphical user interface and information displays. <br /> Seller shall provide equipment to connect the DAS via Ethernet cable, existing Wi-Fi network or <br /> cellular data network at all locations. The means of data connection will be determined during <br /> design. The Buyer will pay for the cost of cellular data service if needed, but not for the modem <br /> or other equipment needed to connect to the cellular network. <br /> The DAS(s) shall provide access to at least the following data: <br /> • Instantaneous AC system output (kW) <br /> • PV System production (kWh) over pre-defined intervals that may be user configured <br /> • AC and DC voltage <br /> • In-plane irradiance <br /> Exhibit B Page 17 <br />
