Lighting, Interior. Xxxx Xxxxxx Grove Middle School currently utilizes a combination of T8 and T5 fluorescent lighting to illuminate the spaces. EEI proposes replacing the existing fixtures with new LED lighting. EEI performed a detailed survey of the interior and exterior spaces in order to identify opportunities in which we can improve lighting quality, reduce maintenance costs, and save energy. The existing lighting demand (kW) per fixture, hours of operation, fixture quantities, and recommended retrofits are based on the physical inspection and site visits conducted by EEI in late 2016. As a result of the survey and analysis, EEI has developed a high efficiency lighting upgrade project that will provide the SAU 33 schools listed with new LED fixtures and LED lamps, resulting in guaranteed annual energy savings and a reduction in electrical demand. LED type lighting provides significant illumination, has longer life expectancy, increased savings in electric consumption, and provides dimming capabilities. Also, by standardizing all fixtures and lamps it will reduce future maintenance requirements. LED fixtures in a school environment have an estimated life of more than 20 years. There is significant maintenance savings when LED fixtures are used due to longer lifespan.
