The Center installed new variable frequency drives (VFDs) to loading dock area fans to ensure optimum air quality. A VFD improves efficiency by adjusting motor speed to more closely match output requirements, which typically results in energy savings. The installation was supported by a $79,781 rebate from Hawai`i Energy, the energy efficiency and conservation program for Hawai`i, Honolulu, and Maui counties, and will result in an energy savings of nearly 445,000 kilowatt hours annually.
The Center’s previous rebates and awards for energy-saving measures have totaled nearly $350,000 for projects including lighting upgrades and a new jockey chiller. When it opened in 1998, the Center was also awarded Hawaiian Electric Company’s Energy Project of the Year for its efficient design.
