Successful green schools

  2. 2. SUCCESSFUL GREEN SCHOOLSFrom the many and different successful green schools found in my research, I have decided to workwith three schools that have tried to go green by taking into consideration the climate of the arealocated, its building and the pupil for the better learning purpose.Council School District # 13, Council, IdahoThe schools located in a cool and dry climate region, the district has 320 students and has a 80,000square feet of interior spaces at a k-8 school and one high school. The school was given a help fromthe Energy Division of the Idoho Department of Water Resources and the Rebuild America Program,the district found a 47 year old boiler and radiant electric heat in the gymnasium of one of the schoolsas obvious targets for energy savings, the school district decided to apply for a U.S Forestry Servicegrant under the Fuels for schools program, which resulted in $386,000 award to use for an advancedbiomass system based on renewable energy technology, after wards the district entered into aperformance contract with Siemens Building Technologies to design a new biomass energy systemfuelled by wood chips, since the water in the system would be heated to only 850F instead of 1800F,the school will use 250 tons of fuels per year rather than 300 tons, water in the system can bereplaced with naturally occurring cold ground water for cooling the building in warmer weather, anadditional savings can be gained by using the 850 F water to preheat water heaters. The district hasimplemented other energy efficiency measures, including new T-8 lamps, new ballasts, light reductionin areas tested for light intensity, and digital controls, the proposed biomass project will require anadditional $2.6 million from voters and a bond, although the bond had not yet passed when this paperwas prepared, superintendent Murray Dalgleish was confident that the community would support inOctober 2004, and ground breaking is planned for spring 2005. Council School Dstrict #13 estimatesthat these improvements will save more than $800,000 in energy cost over next 15 years, the districtwhich plans to make energy efficiency upgrades and the biomass plant part of the curriculum, willalso be a showcase and demonstration for other small schools in the states.Corvallis School District 509J, Corvallis, OregonThe Corvallis School district is located in a temperate and mixed climates and it has eight elementaryschools, two middle school and two high schools serving 6850 students but a new 125,000 squarefoot middle school was scheduled to open in August 2004, and new 230,000square foot high inSeptember 2006. The new school will serve 552 students in the middle school and 1306 students inhigh school, the school board with the help of the district’s Energy Education Coordinator, decidedthat energy efficiency would be a priority for the two new schools, in 1999 the district partnered withan energy consultant, Energy Education, Inc, to identify and implement energy saving projects byfocusing on reducing energy use during off peak hours and encouraging behavioural changes, such asturning off lights and computers when not in use the district has saved $1.5 million from 1999 to2004, a reimbursement from the local utility, Pacific Power, of $5,200 funded a lighting upgrade forthe Corvallis high school cafetweria. A sonsumer’s Power rebate and business Energy Tax Credit(BETC) of $24,000 funded the crescent valley high school gymnasium lighting retrofit. Otherprojects have included installing T-8 lighting; digitally controlled heating, ventilating and air-
  3. 3. conditioning (HVAC) equipment; and energy-efficient boilers. Teachers provided significant input onthe design of the new schools, and both teachers and students have requested energy data for use inclassrooms, the Oregon State Energy Office provided recommendations on community education andoutreach to the administrative staff in the Corvallis School District. Because the schools have hadsignificant energy and monetary savings, the community has been supportive of energy efficiency andrenewable energy projects in the two new schools, in the 2004 report to the superintendent, the schooldistrict called for energy efficiency and renewable energy measures to be pursued for the two newschools, both schools are applying for LEED silver ratings, Energy efficiency and renewable energywill be incorporated directly into the building and curriculum, estimates indicate that the new highschool will use 35% less energy than a conventional school build code, and the middle school 30%less energy. The district is also planning to install a small grid connected photovoltaic system in oneof the elementary school for educational purposes.Elk River School District No.728, Elk River, MinnesotaElk River School District No.728 has cold and humid climates and with 11,000 students in 17buildings, Rogers high School, the first high performance high school in Minnesota, was completed in2003, with a projected 850 students for the 2004-2005 school year and 257,00 square feet, this highschool use 25% less energy than the state standard for such schools, which translate into annualsavings of approximately $175,000, overall the entire project cost for Rogers High School was $32million, in the late 1990’s the district found that additional classrooms were needed and that currentbuilding were becoming increasingly expensive to maintain because of mold and other indoor airquality issues in this variable climate, working with local design firm with experience in highperformance buildings, the Elk River’s director of business and operation began a series of activitiesneeded to construct high performance schools throughout the district.Opening at the same time as Rogers High School was the new Westwood Elementary School with74,000 square feet, this elementary has 475 students, cost $11.5 million to build and is expected tosave $65,000 to $75,000 per year in energy cost saving over code built building. Westwoodelementary is expected to receive a LEED silver certification, the first elementary school in Minnesotato receive this distinction, using passive heating and cooling specifically designed for this climate, aswell as daylighting techniques, the elementary school uses 50% less energy that state standards,according to district personnel there have been days in winter when it costs nothing to heat of theschool, according to Ron Bratlie, the Director of Special Projects, the building maintained its desiredtemperature even with a constant flow of fresh air coming in, as is the case with many highperformance schools, the smaller HVAC equipment needed to heat and cool the structure isresponsible for significant cost reductions, Elk River School District is committed to creating a betterlearning environment for its students and teachers and it is considered to be a leader I the states inhigh performance school construction, Members of the district staff regularly give presentation toother districts on the high performance design and construction process, Elk River school have alsobeen feature in Connexus Energy’s magazine and in a 2003 study by the Environmental Law Institutein Washinton, D.C.The school in the different climate zones described in these research all have receive financial andeducational benefits from a high performance design of their buildings, and many more schools
  4. 4. throughout the country and world are realizing the benefits of high performance design as shown inthe Energy Design Guidelines for high performance schools, the energy efficiency and renewableenergy technologies implemented in retrofits or new construction can provide energy savings as wellas a better learning environment. Because of the environmental impacts are important, these projectsare often more attractive than conventional design practices from a financial perspective, since thesebuildings use less energy than their conventional counterparts, therefore I can safely assume that thismethod are appropriate for schools in South AfricaRefenrecehttp://www.nrel.gov/docs/fy04osti/34967.pdf retrieved at 15:48 on 09/10/2011
