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