The situation.Since opening its first U.S. plant in 1979, Honda has been bringing innovative technologies that enhance American mobility. As a leader in innovation, the company is also focused on environmental responsibility. Honda recognized an opportunity to take environ-mental innovation past the production line and into its U.S. headquarters in Torrance, California – a multi-building campus that houses research and development, parts distribution, administrative and business development personnel supporting the automaker’s North American business – by exploring a new lighting strategy.
The buildings on American Honda’s 1,000,000 square foot campus were equipped with standard T12 and first generation T8 fluorescent lamp and ballast systems, as well various incandescent and metal halide fixtures. Honda knew that a campus lighting retrofit would yield energy savings, but also wanted to ensure that the most innovative, technologically advanced solutions were considered to match their own state-of-the-art company DNA. The carmaker enlisted SYLVANIA Lighting Services (SLS) to conduct a thorough energy audit, provide a comprehensive lighting recommendation and execute the new system installation. With the widespread capabilities and extensive experience of SLS on Honda’s side, the leading car company set out to increase lighting efficiency at its American home base.
The solution.SLS experts first assessed the existing lighting systems installed years ago at the Honda campus. A team of SLS professionals discovered that in some areas a simple re-retrofit and re-lamping strategy would promote energy efficiency, save money and improve the quality of lighting. However, SLS acknowledged Honda’s desire to incorporate innovative new technology, like LED systems, into their new lighting strategy. SLS then created a lighting approach that integrates the most efficient and cost effective lighting systems with exceptional product life starting in the lobby of American Honda’s administration building.
SLS recommended using the OSRAM 55-watt D6 LED Retrofit Kit to replace the existing 175-watt metal halide fixtures. Typically used to replace outdoor metal halide and other HID area-lighting lamps and fixtures, this was the first time the D6 kit was used for an indoor, commercial office application. SLS worked with the D6 kit for interior mounting customization. The installed retrofit kits save Honda 88,300 KWh or $13,245 per year because of the efficiency of the LED technology.
The solution continued.Beyond the lobby installation, SLS executed a comprehensive lighting retrofit for multi campus buildings. Using SYLVANIA OCTRON® 800XP® and PENTRON® T5 HO SUPERSAVER® fluorescent lamps, SLS completed the 25,079 lamp retrofit with accompanying OSRAM QUICKTRONIC® high efficiency, electronic T8 and T5HO ballasts. Furthermore, American Honda was able to capitalize on the industry leading turnkey warranty program with the System Solution.
SLS also implemented extensive use of light management systems to optimize the efficiency of the lighting system throughout the campus. For example, SLS installed an advanced occupancy sensor system to illuminate areas only when they were in use. While the sensors operate constantly, they are self contained requiring no additional power to operate.
A key component to this retrofit’s viability was utility incentives. SLS was able to maximize the utility contribution to this project by seeking innovative programs that paid greater rebates than typically available. This effort helped Honda receive an additional 30 percent incentive, with the overall rebate equaling over 20 percent of the total project costs.
The product.The OSRAM D6 LED Retrofit Kit is typically used in outdoor applications, including industrial parks, city street lighting and parking lots. The retrofit replaces less efficient technologies with a LED light source, improving the application by providing a better lit, more welcoming and secure atmosphere. LED Retrofit Kit systems are designed for maximum long-term performance, low cost operation and ease of installation without having to replace an entire fixture; the kit can be easily installed in a wide variety of fixtures.
SYLVANIA OCTRON 800XP and PENTRON T5 HO SUPERSAVER fluorescent lamps are among the most efficient in the industry, providing up to 42 percent longer life, higher initial and maintained lumens and improved color rendering. To maximize the energy efficiency of the OCTRON 800XP SUPERSAVER lamps, SLS paired them with OSRAM QUICKTRONIC QHE HO ballasts. The QUICKTRONIC High Efficiency electronic ballasts operate OCTRON and PENTRON lamps with maximum efficacy and high lumen output, offering 30-44 percent energy savings over the previously installed T12 and T8 systems.
The effect.Combined, the lobby of American Honda’s administration and the multi building retrofit projects will save Honda 1,387,824 kilowatt-hours each year, lessening the company’s carbon footprint by 749,508 pounds of CO2 emissions annually.
The bottom line.By achieving an estimated yearly energy cost savings of $166,538.88 and earning rebates for its efforts from the state of California, Honda expects to see full payback for the project in one and a half to two years. Not only does the new lighting system SLS installed greatly lower American Honda’s energy consumption, but, because of the extended lamp life of the installed technologies, maintenance costs are also reduced, leading to even further cost savings for the automaker’s U.S. headquarters.
