Over a six year period, the Hawaii Natural Energy Institute has partnered with Project Frog of San Francisco to construct five zero net energy research platforms used as classrooms but doubling as energy efficiency laboratories. These platforms are fitted with 5 to 8 kW photovoltaic (PV) systems to generate more energy than they consume. After construction, these structures were continually monitored by HNEI and MKThink, also of San Francisco, to validate energy generation and consumption.

Five research platforms were constructed under this funding: One at Ilima Intermediate School in Ewa Beach; two at Kawaikini New Century Charter School in Lihue, Kauai; and two at the University of Hawaii at Manoa.  The zero net energy platforms were constructed to evaluate energy consumption and generation, and indoor comfort parameters in naturally ventilated, mixed mode structures, relative to external environmental conditions. The UH Manoa platforms are also being used to test other cutting edge technologies such as advanced occupancy sensing and adaptive wireless communication methods for transmitting energy and environmental factors to remote users.
