The Missouri University of Science and Technology is making efforts to be a little greener this year with the installation of newer, more energy efficient lighting in many buildings on campus. The improved lighting fixtures will save approximately 700,000 connected watts, with total savings of 2,400,000 kilowatt hours of electricity usage annually. The University will also see a $220,000 reduction in utility expenses and a six percent overall reduction of energy usage. Replacing or updating the lighting fixtures has cost an estimated $712,855. The project began during the early part of 2007, with a quarter of the work done by August. Most of the work was completed by November, but a few lighting fixtures still need to be updated. Over 10,000 lighting fixtures in 21 buildings have been either updated or replaced. The buildings with the improved lighting are: Basic Engineering, Gale Bullman Multipurpose, BOM Two, Castleman Hall, Comp Flow Lab, Computer Science Building, Engineering Management Building, ERL, Fulton Hall, General Services Building, Harris Hall, Historic Bureau of Mines, V.H. McNutt Hall, Norwood Hall, Parker Hall, Physics Building, Recreation and Intramural, Rock Mechanics Center, Schrenk Hall, Student Design Competition Center, and Temporary Research Building. The upgrade to energy efficient lighting consisted of several types of improvements. Fixtures that previously contained T12 fluorescent lamps were either replaced or upgraded to use T8 fluorescent lamps. T8 fluorescent lamps have a narrower tube, in addition, using 43 percent less energy than a T12 lamp. In some cases, the number of fixtures was reduced as well. The 32-watt T8 lamps previously used were also replaced by 28-watt T8 lamps. Compact fluorescent lamps replaced the incandescent lamps, saving from 70 percent to 90 percent of the energy usage. High bay fluorescent lamps also replaced interior high intensity discharge lighting fixtures in some buildings and reduce energy consumption by 50 percent. |
