OP-16: Life Cycle Cost Analysis

The LED Lighting Project was implemented in 2014 as a means to reduce energy consumption and limit the impact on the environment and increase light visibility, while also lowering utility and maintenance costs. The LED bulbs have a significantly longer life than the metal halide bulbs that they replaced, which additionally reduces maintenance costs. In addition, LED bulbs draw about half as much power as metal halides. This leads to significant reductions in the demand for energy, which is generated on site. It is estimated that this project will reduce demand by about 134,000 kwh each year. Although LED retrofits are generally capital intensive, the energy reduction brought about from their use ends up saving money in the long run. The SBU Wolf Ride Bike Share offers students, faculty, staff and visitors with a sustainable, healthy transportation alternative. One of its goals is to reduce the amount of emissions in the air by providing an alternative to combustion engine vehicles. Each station is completely solar powered to make it a truly zero emission alternative. In addition to environmental advantages, Wolf Ride also serves to limit roadway vehicular congestion. SBU Transit Vehicle purchases serve to limit emissions as well. With the purchase of 10 electric vehicle charging stations, eight Toyota Prius vehicles and six all electric GEM cars the university is moving away from low efficiency, combustion driven vehicles as a means to reduce its carbon footprint. Furthermore, Stony Brook University acquired a plug-in, diesel hybrid bus from the Long Island Power Authority (LIPA) in Fall 2010. The plug-in, diesel hybrid bus was originally manufactured by El Dorado National as a diesel powered bus and later converted to a dual mode, electric / diesel hybrid drivetrain by the Odyne Corporation for the Long Island Power Authority / National Grid. Also, Stony Brook University converted a Ford E450 gas powered shuttle to a gasoline hybrid in Spring 2011. The Ford E450 shuttle was originally manufactured by the Ford Motor Company and Turtle Top Inc. as a gasoline powered 21-passenger shuttle and converted to a single mode gasoline hybrid drivetrain by ElectroMotive Designs, LLC for Stony Brook University. These changes lead to an overall drop in costs from fuel savings.
