Meigs Local Schools had recently built a new elementary and middle school and renovated their high school, all to current standards. After construction, the new buildings used significantly more energy than expected, resulting in major unbudgeted expenses for the district. Through Limbach’s Utility Auditing Service, the school administration became aware of energy saving measures to reduce this expense. Limbach partnered with the district to develop a program to reduce energy use. The two cornerstones of the program were to harvest heat energy from the chillers and to replace the existing control system. The recovered heat is used for the summer dehumidification process in place of heat from the gas boilers. As a result, the schools no longer run their boilers during cooling season. A complete control system upgrade helped optimize energy usage. .
Objective To reduce extraordinarily high energy costs in new school buildings
• • • • •
Saved over $190,000 in electrical and gas costs in the first year after implementation Generated a simple payback of the project in less than 5 years Reduced electric usage more than 30% and reduced gas usage more than 40% Reduced greenhouse gas emissions by 1450 tons/year, the equivalent of the energy used by 120 homes each year All three buildings improved significantly on the US EPA’s Energy Star Performance Assessment, and two of the buildings improved over 50 points • Classroom learning environments have easy-to-use systems for enhanced comfort levels, better ventilation and improved indoor air quality
