SIEMENS Examples of this may be a residential neighborhood lit by all 70HPS cobra heads, with a single 150W found along the same road, In the same application. In short, Siemens looks at that data and asks; does this make sense? Our records of these system Improvements have shown to help our customers achieve an additional 1-2% in energy and related cost savings. Some may consider this insignificant, but our experience has shown this to be a value -add step from which our customers such as Huntington Beach and Rialto continue to gain rewards. Siemens will provide various options and the financial considerations associated with each to aid in the decision making process. The end product should be relatively uniform lighting levels based on street classification and pedestrian activity. Technologies & Comparisons Siemens, at Its heart, is a technology company. However, Siemens is not a street light manufacturer, nor are we exclusively tied to any one vendor in the market. This allows us to hold a "vendor neutral" stance, end evaluate the customers options from an impartial perspective, converting Industry data Into customer based Information. Siemens looks at the quantitative and qualitative benefits of each considered vendor, to use with the customer in determining the best solution for them. Throughout our years of experience, Siemens has developed a scoring methodology that puts multiple vendors into the same basket, in an attempt to generate a true apples -to -apples comparison. A primary scoring mechanism is the total cost of ownership (TCO) to the customer for every solution. This is particularly important In areas 11ka Santa Ana, where utilities have a bracketed — or "tiered" — billing rate, which is not based on the actual wattage of each fixture type. Because there are no standardized wattages for LED light sources, utility companies like Southern California Edison (SCE) base the billing wattage of each fixture type, on a 5 - Watt midpoint bracket system. This means that fixtures with LED wattages of 15-20W, will be billed as 17.5W, or fixture types with an LED wattage ranging from 50-55, will be billed as 52.5W. These bracketed 'systems are a main consideration for Siemens when identifying a vendor solution, and comparing it to others. Attachment 5 of the RFP lists (6) of the leading LED street light manufacturers in the US market. Of these six manufacturers, five of them have gone through at least one LED chip upgrade in their product offerings. Siemens had recognized this and provided a more current package together for each of these, while still considering the older fixtures that are still available, and comparing the two. Siemens is familiar with both the quantitative and the qualitative benefits of a manufacturers' LED street lighting system. Cost, lumen output, and energy savings are certainly a main focus for Siemens in our vendor scoring methods; however, they are not the only topics considered. Items included but not limited to are: • Lumen output • Rated Lifetime • Energy efficlency • Luminaire & Component Warranties • Available Correlated Color Temperatures (CCT) • Available distribution patterns • Ease of installation and maintenance Being a self performing ESCO, and maintenance contractor with over 300 maintenance contracts, we gravitate toward lighting fixtures that are well-designed and provide the longest proven maintenance - Page 16 55A-373
