Energy benchmarking studies

State of Hawaii facilities on Oahu

The benchmarking study determined the electrical energy consumption and distribution for the State of Hawaii facilities on Oahu by State agency, building occupancy type, and end use. Additionally, benchmarking for various Energy Conservation Measures (ECMs) and their associated energy savings potential for State facilities on Oahu were presented. The benchmarking data for the study is based on several sources, including previously conducted energy audits of various State buildings on Oahu, electricity billing history by meters,
information on previously implemented ECMs identified through Hawaiian Electric Company’s Demand Side Management (DSM) rebate history, building occupied square footage area information provided by DAGS for certain State facilities on Oahu from 2001 records, responses from several State agencies for an energy survey request of large facilities, and an energy benchmarking study for the UH Manoa Campus conducted in 2004. ECMs documented in the reference sources, integrated with additional engineering observations, were generalized for all the State facilities on Oahu as applicable. The ECMs were categorized by energy savings potential and payback period. Project was completed in 2006.
