Dayton Power & Light awarded the Kettering Health Network an energy efficiency rebate of $200,700 for a project that upgraded the air conditioning system at the Kettering Medical Center campus in Kettering, Ohio.
The project, which was implemented by Siemens, installed a Demand Flow chilled water plant optimization control system that upgraded the air conditioning system’s control logic, installed high accuracy sensors and variable frequency drives, as well as other hardware to achieve the higher energy efficiencies.
As a result of the energy efficiency upgrade, the Kettering Health Network is expected to save 1,938,008 kWh a year and save $135,000 a year in electricity costs.
Kettering Health Network applied for the rebate in 2013. The system upgrade, which controls four chillers with the capacity of 3,400 tons of cooling was completed in 2014. DP&L auditors collected data before and after the installation to determine the amount of savings and to verify the improvement in energy efficiency.
