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