In 2015, the University of Hawaii (UH) and the Hawaii Legislature established a goal for the UH university system to be net-zero by Jan. 1, 2035. Of all the campuses in the UH system, the University of Hawaii Maui College is on target to be the first to supply 100% of its energy needs through on-site photovoltaic systems coupled with battery storage, and it will do so 16 years ahead of schedule.
When it becomes operational in 2019, the UH Maui College PV plus storage system will be able to eliminate the campus’s fossil fuel-based energy use. The project is part of a partnership with Johnson Controls and Pacific Current and is currently in its second phase. Phase one saw the implementation of energy efficiency measures at UH Maui College and across all of the UH campuses. Phase two includes additional energy efficiency upgrades and the installation of the on-site solar PV coupled with battery storage.

Phase two will bring the total on-site capacity to 2.8 MW of solar PV and 13.2 MWh of battery distributed energy storage at UH Maui College. Phase two will reduce the fossil fuel energy consumption across all of the five UH campuses by ~14 GWh annually (45%) and add ~13 GWh renewable energy generation.
By the end of phase two, the UH Oahu campuses will reduce their use of fossil fuel for energy by 98% (Leeward Community College), 97% (Honolulu Community College), 74% (Kapi’olani Community College), and 70% (Windward Community College).

A new study presses for measuring embodied carbon in industrial buildings
The embodied carbon (EC) intensity in core and shell industrial buildings in the U.S. averages 23.0 kilograms per sf, according to a recent analysis of 26 whole building life-cycle assessments. That means a 300,000-sf warehouse would emit 6,890 megatons of carbon over its lifespan, or the equivalent of the carbon emitted by 1,530 gas-powered cars driven for one year. Those sobering estimates come from a new benchmark study, “Embodied Carbon U.S. Industrial Real Estate.”
