In recent years, the University of Hawaiʻi and the Hawaiʻi Legislature set an important but ambitious goal: the 10-campus university system would be net-zero by 2035. In 2020, Leeward Community College became the first UH campus to achieve net-zero energy—and among the first in the nation to generate virtually 100% of its energy from on-site solar photovoltaic (PV) systems, coupled with battery storage, to eliminate all fossil fuels. UH Maui College became the second UH campus to achieve net-zero energy.
This was accomplished following a performance contract that reduced energy consumption through various energy efficiency measures. Leeward CC’s energy efficiency efforts are guaranteed to save $269,000 in energy and operational costs for the first year and $8.4 million over the project’s 20-year performance period. UHMC’s efficiency efforts are guaranteed to save $433,000 in energy and operational costs for the first year and $10.2 million over the project’s 20-year performance period.
The UH Community Colleges partnered with Johnson Controls and investor Pacific Current (a tier 1 subsidiary of Hawaiian Electric Industries) for Phase 2 of an ongoing renewable energy effort. This phase focuses on assisting five UH community college campuses to virtually eliminate fossil fuel consumption.
The collaboration was created to do two key things: (1) make energy efficiency upgrades that reduce the deferred maintenance backlog across the five campuses (e.g., a lighting retrofit, the replacement of a chiller, etc.), and (2) install on-site, 8.1 MW solar PV systems with 45.8 MWh of battery distributed energy storage. Johnson Controls developed the system; Pacific Current owns it.
With the implementation of Phase 2 of its renewable energy program, the five impacted UH campuses will reduce their annual fossil fuel consumption by ~14 GWh, and add ~13 GWh of renewable energy generation. At Leeward Community College, 3,579 PV modules were installed on the campus capable of generating 1.678 megawatts (MW) of power annually, enough to power 230 homes, and offsetting greenhouse gas emissions equivalent to 4,642 barrels of oil a year. At UH Maui College, 3,300 PV modules were installed capable of generating 1.58 MW of power, enough to power 200+ homes annually and offsetting greenhouse gas emissions equivalent to 4,400 barrels of oil a year.
The project has already won two national awards from Environmental Leader: Project of the Year and Top Project Judges’ Choice Award. The awards panel recognized the project for setting “the standard for universities, colleges and other campuses to achieve net zero energy status” and for proving “that 100% renewable energy projects are technically and economically viable.”
While partnering with the private sector was important to the success of the project, it is important to note that UH is advancing toward its goal of being net-zero by 2035 in a variety of ways. UH West O’ahu, for example, recently installed its own PV system. Kauaʻi Community College also installed a PV array with batteries. The UH Marine Center’s new PV battery system was completed in collaboration with the Hawaiʻi Natural Energy Institute.
UH encourages students, potential students, and the public at large to engage with its initiatives. Five community college campuses offer an Academic Subject Certificate in Sustainability, a multidisciplinary, embedded certificate that can be earned along with any other associate’s degree. UH also makes its Net Zero Dashboard available to all to track its progress.
