American Universities Becoming Energy Efficient Essay

1507 words - 6 pages

Universities Consume Energy Like Mini-CitiesColleges and universities are actually office buildings, restaurants, retail shops, multi-family dwellings, sports facilities, entertainment complexes, and schools rolled into one. Today, these mini-cities face severe budgetary challenges as they strive to operate, update, and replace aging, inefficient buildings. Enrollment is rising along with energy costs and student demand for energy-intensive amenities like air conditioning, high-speed Internet connections, and voice mail.The Good News?Many universities are realizing they can reduce operating costs and improve the campus environment by making energy-efficient building improvements. The greatest potential for energy savings comes from improvements in building controls. Some buildings burn the midnight oil, but most don't. Central monitoring controls can regulate off-hour lighting, heating, and cooling across the entire campus.Efficient lighting and dormitory appliances and equipment; improved heating, ventilation, and air conditioning systems; and increased use of daylighting are some other measures that can add up to energy savings of more than 30%. Many universities target their most inefficient systems first, then use the energy savings to fund additional capital improvements.Centralized ControlsCentralized building controls or building automation systems can be used to automatically turn on, turn off, or dim electric lights around a building. In the morning, the centralized control system can be used to turn on the lights before employees arrive. During the day, a central control system can be used to dim the lights during periods of high power demand. And, at the end of the day, the lights can be turned off automatically. A centralized lighting control system can significantly reduce energy use in buildings where lights are left on when not needed.Ways to Save*Reduce energy costs by installing centralized control systems to control off-hour heating, cooling, and lighting across the campus*Reduce lighting loads and improve comfort by incorporating daylighting systems and energy-efficient lighting such as T-8, compact fluorescents, and metal halide fixtures*Save energy and water with solar water heating systems and low-flow faucets, showerheads, and toilets*Specify ENERGY STAR products for administrative offices, classrooms, and student housinghttp://www.eere.energy.gov/buildings/university/index.cfm?flash=yesEnergy Use in Colleges And Universities32% Space Heating24% Water Heating22% Lighting05% Space Cooling17% Other"«The University of Michigan has already realized significant emission reductions by using natural gas in its cogeneration power plant, adopting alternative fuels for some of its fleet vehicles, and retrofitting buildings with efficient lighting and HVAC systems. Nevertheless, the University of Michigan is in an excellent position to reduce greenhouse gas emissions further through its energy-efficiency programs for buildings...
