As a result of Elara’s design to replace and upgrade the existing central plants serving Maine South High School and Maine West High School, Maine Township High School District 207 has been approved to receive $260,270 in incentive funding due to the demonstrated energy efficiency of the new central plants.
Through the initial stages of a master plan for the entire School District, Elara identified the opportunity to convert the existing inefficient heating system serving Maine West High School from low pressure steam to hot water heating fed by a high-efficiency condensing hot water boiler plant and to install a new dedicated domestic hot water and pool heating plant. This work included replacement of the existing steam absorption chillers with new high-efficiency electric chillers, upgrade of ten air handling units, and the elimination of nine heat exchangers.
Elara similarly identified the opportunity to replace the existing high temperature/high-pressure hot water boiler plant at Maine South with a new high-efficiency condensing boiler heating plant and to install new dedicated domestic hot water and pool heating plant. This work included the elimination of ten heat exchangers and the consolidation of the space heating boiler plants. Also as part of the central plant upgrade project, new state-of-the-art direct digital control building automation systems were also installed to replace existing pneumatic controls at both high schools.
Additional benefits of Elara’s central plant upgrade design include replacing aged equipment in need of repair with new higher efficiency equipment with lower operating costs, reducing maintenance through the elimination of equipment, and improving comfort through state-of-the-art controls. The projects were completed on-time and under budget with $260,270 ($159,639 for natural gas; $100,631 for electric) in incentive funding approved through local utility companies.
