The primary goals of this lighting project are: 1. Guaranteed Light Levels: Selection of appropriate light levels impact the safety of the players and the enjoyment of spectators. Therefore, light levels are guaranteed to not drop below specified target values for a period of 10 years. 2. Environmental Light Control: Minimize spill light to adjoining properties and glare to the players, spectators and neighbors. 3. Life-cycle Cost: To reduce operating costs, the preferred lighting system shall be energy efficient and cost effective to operate. Accordingly, efficacy should be a minimum of 135 lumens/watt and no more than 48 kW of power shall be used for the entire site (football, soccer, & track) 4. Control and Monitoring: To reduce system and labor costs and allow for optimal operational flexibility of the lighting system, the customer requires a wireless control system. The system shall be capable of instant on/off control to reduce energy consumption. The system must permit multiple users with varying levels of access, and scheduling in advance based on both time and sunset/sundown.
