Administrators with a Missouri school district say they expect to save $27,000 in energy costs, thanks to infrastructure upgrades that include a new HVAC system.

The work at four Dunklin R-V School District buildings, located in the St. Louis suburb of Herculaneum, Mo., was so significant, it earned the Energy Efficiency Leader Award from Ingersoll Rand’s Trane brand.

“These upgrades not only increase energy and operational efficiency and reduce energy costs, they also enable the district to avoid significant capital costs which would have been needed to keep the buildings operational,” said Stan Stratton, district superintendent. “Most importantly, they improve the academic environment to help us better fulfill our chief objective: educating our students.”

Officials hope that modernizing the HVAC system at the district’s Taylor Early Childhood Center will help the generate money through boosting enrollment in the early education programs at the center. High-efficiency HVAC units were placed on the recently fixed roof, and electrical and water piping and heating were also upgraded.

New bathrooms ensure the structure meets the Americans with Disabilities Act requirements and upgraded lighting saves energy.

At the district’s “butterfly” building, a new high-efficiency HVAC system is paired with a new roof and energy-efficient lighting. Senn-Thomas Middle School has two new 15 seasonal energy-efficiency rating packaged rooftop units and lighting tied to occupancy sensors.

Dunklin’s Pevely Elementary School also saw boiler systems replaced with new HVAC units.

Everything has been tied into building automation systems to ensure central control and efficiency.

The upgrades will save the district future capital costs of almost $300,000 annually, Trane said.
