Energy Efficiency Pays Off for One Kalakaua Senior Living

Posted May 29, 2013

Public and private sector energy leaders joined Hawaii Energy, the energy efficiency and conservation program for Hawaii, Honolulu and Maui counties, today as the program presented One Kalakaua Senior Living with a check for $73,678. The ceremony was held in recognition of extensive energy efficiency measures that One Kalakaua recently completed.

“We are excited that One Kalakaua Senior Living took advantage of our customized commercial incentive offering to help bring this energy efficiency project to fruition,” said Joe Simpkins, Hawaii Energy Senior Energy Project Manager. “We encourage everyone to visit our web site at to learn about the many energy conservation and efficiency offerings available for both residents and businesses.”

The One Kalakaua project involved the installation of a new 180-ton Smardt chiller, which utilizes Danfoss Turbocor’s oil-free, magnetic-bearing centrifugal compressors with variable frequency drives to replace two inefficient 180-ton chillers, as well as an automated energy management system that monitors and controls the various components associated with this upgrade. An energy-efficient heat pump for hot water was also installed, greatly decreasing energy demand from two rooftop gas-fired boilers.

“Without the incentive funding, One Kalakaua would not have been able to complete this project as soon as we did,” said Michelle Kakazu, One Kalakaua Senior Living Executive Director. “Generating savings through energy efficiency measures is a major goal of ours, so this project was definitely a win-win for all involved.”

All together, the project will save One Kalakaua an estimated 448,517 kilowatt hours (kWh) annually and reduce their demand by 51.2 kilowatt (kW), which equates to $119,206 in savings per year based on $0.263 per kWh and $24.34 per kW demand.

Hawaii Energy’s incentives help commercial electric utility customers invest in energy-efficient equipment and technology. For more information about incentives, visit
