Aina Haina Public Library, located at 5246 Kalanianaole Highway, will become the first Oahu library in the Hawaii State Public Library System (HSPLS) to install a photovoltaic system on its rooftop as a cost-saving measure to reduce rising energy costs. The $605,053 project began in February and is scheduled for completion later this summer.
A photovoltaic system (or PV system) uses one or more solar panels to convert sunlight into electricity. The new "green" North Kohala Public Library (Island of Hawaii), which opened in November 2010, was the first HSPLS library to install a photovoltaic system.
The two HSPLS libraries are among an increasing number of new or existing Hawaii State Government buildings that have or will become energy efficient, resulting in long-term savings for taxpayers and reduce our dependence on foreign oil.
In a study prepared by Ronald N. S. Ho & Associates, Inc., Aina Haina Public Library was rated the highest among five selected libraries for its optimal building construction, access, orientation and site/weather conditions conducive for photovoltaic power generation, and highest estimated annual savings.
The Library's current average monthly energy usage is 10,253 kilowatt hours (kWh). The new PV system will generate 7,300 kWh per month or approximately 71.2% of the Library's monthly energy needs.
The contractor for the project is RK Construction Co., LLC. In addition to the photovoltaic system, the project included a roof replacement, electrical and interior work.
