West Hawaii Explorations Academy
Energy Smart Schools Project Final Report
Executive Summary
West Hawaii Explorations Academy (WHEA) is a public charter high school located on the Pacific Ocean on the
west side of the Big Island of Hawaii. WHEA is a unique school, the curriculum is project based; students learn
by working on `real-world' projects. Due to the unique curriculum, WHEA's campus is mostly outdoors and
utilizes the resources that are readily available; solar energy, deep and surface sea water. Another way WHEA is
unique is that the campus is part of the Natural Energy Laboratory of Hawaii Authority (NELHA) Complex, a
research park. NELHA is a complex that focuses on altemative energy use, aquaculture and biotechnology
utilizing cold deep seawater. The many tenants in the NELHA complex are engaged in cutting edge research and
development. WHEA has developed a relationship with the some of these tenants, this relationships allows
students who attend WHEA employment opportunities as well as opportunities to work with mentors who are
conducting research within the park.
There are approximately 120 students currently attending WHEA. These students range from 9th grade to 12th
grade. WHEA's curriculum is project driven, or project based. Project based learning (PBL) focuses on leaming
through real world projects. Theses projects are centered in three main areas of emphasis, Ocean Science, Plant
Life Studies and Alternative Energy.
WHEA has a long and prestigious history in alternative energy competitions, going back ten years when WHEA
garnered national attention in the Tour de Sol and the World Solar Challenge. WHEA won the high school
division of the World Solar Challenge in 7990 and has continued to be an innovator in altemative energy
education.
One of the projects that students who attend WHEA can participate in is the electric car project. The Electron
Marathon is a competition that is held on Oahu each year. The objective of this competition is to build an
electric car, using a kit, provided by the Hawaiian Electric Company. Each school then competes in a marathon,
the car that completes the most laps on [he track in an hour wins the race. The school is also judged on
documenting their research and development of the car, presenting the project to a panel ofjudges and a vehicle
safety inspection. The focus of this project is not necessarily on winning the race, but the research and
development that the students must go through to build their car. Each year students who participate in this
proj cct start by leaming the basics of electricity, aerodynamics, auto-mechanics and of course, teamwork.
WHEA consistently performs well in this annual competition, and currently holds the course record.

The Energy Smart Schools (E$S) project fit very well with the current curriculum at WHEA. The activities for
the E$S project included the following categories:
• Saving Electricity
• Alternative Energy Education
• Dissemination
The activities focused on outreach and ongoing energy education. WHEA provides tours [o over 3000 grade
school students who visit the school as part of the Aloha Kai program. Students whojoined the E$S project
created an interactive presentation on solar energy for the students who attend an Aloha Kai tour. Student who
attend the tour come from the local elementary schools, schools from the Hilo side of the island and even schools
from outer islands, like Oahu. Students at WHEA also provide tours to guests of NELHA, parents and adult
visitors from schools and businesses across the nation.
All students at WHEA were given a course on energy, Energy Strand. This course was designed to reflect the
physical science standards in the Hawaii Content and Performance Standards. In this course, students learned
about the different sources of energy (especially solar energy), energy issues, such as the greenhouse effect or the
use of alternative energy sources as compared to the use of fossil fuels, and built an electric motor. The students
were given an experiment to perform and asked to write a lab report. The students were given a small solar
panel, a volt and amp meter and asked to determine the angle of inclination that produced the greatest amount of
energy.

WHEA students learning about electricity in the Energy Strand.
Students who were especially interested in energy joined the E$S project Students in the E$S project learned
how to audit the electricity used on campus. They audited the campus and they created a chart to demonstrate
how the electricity is used on campus.

Then students determined the rate of electrical usage to discover opportunities to reduce daily electrical usage.
For example, students audited to the lighting fixtures in the few buildings that utilize lights during the day (most
of the campus utilizes day lighting, due to the outdoor nature of the majority of the campus). Students found that
the lamps in use were T-8 fluorescent lamps which are the most efficient lamps available. These lamps save
from .018 kW-.074 kW per fixture. Since WHEA already had these lamps in place, retrofitting was unnecessary.
Also, students audited the refrigerator that was in use on ehe campus. Students discovered that by purchasing a
new, more efficient refrigerator, that the elecMcal savings for the school would be 1,700 kW per year. Students
also initiated a computer turn off program, where school computers were shut down at the end of each day,
resulting in a 30% electrical saving per year. In the interest of saving electricity, students researched a low
pressure compressor with a more efficient motor. This retrofit reduced electric costs by 6% per year.

WHEA's photo voltaic system
E$S students had an exciting opportunity to team first-hand about utilizing solar energy to reduce the amount of
electricity needed from fossil fuels. WHEA installed a 10 KW photo voltaic system. This system has an average
output of approximately 50 KWH per day AC which supplies 1 I O percent of school needs at peak hours. 'Hie
use of a photo voltaic system is ideal due to WHEA's location. WHEA is located on the West Hawaiian coast
that receives the most sunshine in the Lnited States. to addition, the school's electrical needs tend to rise and fall
with the sun, school begins operating after sunrise and is generally closed after sunset. WHEA is also able to sell
the excess electricity back to the utility company, Hawaii Electric and Light Company.

WHEA students then took what they learned about energy use and solar energy to create an interactive
presentation as part of the Aloha Kai tour. Aloha Kai is a project that offers a tour of the campus projects to
approximately 3,000 students from other schools. The E$S portion of the tour gave students an opportunity to
teach other students how solar energy is produced in a photo voltaic cell. The students set up a photo voltaic cell
that is attached to a light bulb, an electric motor that spins a disk and a water pump. Usually the students who
participate in Aloha Kai Tours are younger students, so this is an exciting opportunity for WHEA students to
teach the next generation of students about solar energy and how to protect the environment.

These students worked not only on the WHEA campus, but also had an opportunity to audit a business.
Originally, the students planned to visit several of the tenants in the NELHA complex. However, due to the
competitive nature of the research and development that takes place in these businesses, the tenants were not
interested in having the students audit their energy use. Fortunately, NELHA, the state agency that is responsible
for leasing the land and the resources within the park, was willing to allow students into their buildings to audit
the energy use. Students were very interested to team about the technology that uses cold seawater (39 degrees
F.) from offshore depth of 2000 feet to air condition the entire 10,000 square-foot NELHA building. This
technology saves 54,000 per month in electricity costs. WHEA is researching the possibility of using this
technology to air condition classrooms when the campus is relocate to a nearby site. Also, students were able to
audit the lighting fixtures at the NELHA facility; the facility utilizes 394 florescent lamps, 98 lamps in the office
and 148 lamps in each conference building. If NELHA would retrofit and install T-8 fluorescent lamps, the most
efficient lamps available, they would save from .018 kW to .074 kW per fixture. This would create a total
electrical savings of7.095 kWh to 29.2>6 kWh.

In January 2004, students who participated in this project created a power point presentation to present at the
Regional Seattle Peer Forum of Rebuild America in Scottsdale Arizona. "Ilre students presented their findings in
the form of a power point slide show to the participants of the conference. This was an excellent opportunity for
students to share the unique outdoor setting of WHEA, the project based curriculum and the NELHA complex
with their peers. Also, students were exposed to presentations from other schools that were more traditional,
utilizing retrofitted lighting to create substantial energy savings. Students also were able to see different ways of
graphing electrical savings and environmental benefits for presentations.

Report of Activities:
Saving Electricity
New refrigerator
WHEA students anal yced the efficiency of the old refrigerator and discovered that if WHEA purchased a new,
more efficient model, then the new refrigerator would pay for itself in two years. The previous refrigerator
consumed approximately 2200 kWh per year. The new, more efficient model will consume approximately 500
kWh annually, a savings that will allow WHEA to recover the cost of the new refrigerator in two years
(50.22/kWh).
Computer turn off progam
The students at WHEA initiated a computer turn off program. Basically all the computers on campus are turned
off during non school hours. T'he computer turn off program has saved 30% of the annual electric usage at
WHEA.
Low pressure compressor
After researching compressors, students learned that a low pressure wmpressor with a more efficient motor will
reduce electric costs by 6% per year. Students replaced the old motor with more efficient motor, which saves
6% per year.
Photo Voltaic System
WHEA installed a 10 KW photo voltaic system. This system has an average output of approximately 50 KWH
per day AC which supplies 1 10 percent of school needs at peak hours. The use of a photo voltaic system is ideal
due to WHEA's location. WHEA is located on the West Hawaiian coast that receives the most sunshine in the
United States. In addition, the school's electrical needs tend to rise and fall with the sun, school begins operating
after sunrise and is generally closed after sunset. WHEA is also able to sell the excess electricity back to the
utility company, Hawaii Electric and Light Co.

Alternative Energy Education
Energy Strand
In an effort to educate all WHEA students on the basics of energy, all students attended an energy class, Energy
Strand. The goal of this class is to provide students with a working knowledge of electricity, alternative forms of
energy and energy issues. This course was designed to address the physical science standards from the Hawaii
Performance Standards. Worksheets were used to practice calculating volts, amps, kilowatt hours. Students
performed an experiment to determine the most effective angle for a solar panel. Energy issues, such as the
greenhouse effect and alternative energy sources compared to fossil fuels, were researched and explained in an
issue paper. Students built several electric circuits: buzzer, series and parallel lighting, electric motor.
E$S Proj cct
E$S became a teacher directed project at WHEA, where students who were interested in learning in depth about
energy were able to survey home energy usage, analyze ways that WHEA could be come a more energy efficient
school, and analyze the electrical usage of a commercial building in the NELHA research park. These students
came up with many ideas on making WHEA more energy efficient (see energy savings). They were able to
implement their ideas and study the effect of these changes. The installation of a photo voltaic system offered an
excellent opportunity for the students to see first hand how an alternative energy system like this can impact
electricity consumption. "These students also attended a national conference in Scottsdale, Arizona to share their
experiences and discoveries.
Dissemination
Aloha Kai
Aloha Kai is a teacher directed project at WHEA, whose goal is to educated students on the conservation and
preservation of the enviroument. WHEA students who participate in Aloha Kai, research an area they are
interested in and then present this information to students who attend the tours. Students who attend this tour
will team about the fragility of the coral reefs, the various native species offish and fauna and other projects on
campus. The students who joined E$S created an interactive presentation that explains solar energy and how
altemative forms of energy are important to protect our environment. Aloha Kai provides tours for over 3000
(see attachment) students annually. These students come from local elementary schools from across the state.
The interactive presentation explains the concept of solar energy and how the sun can provide electricity to run
lights, motors and water pumps. The ESS project members have the students experiment by blocking the sun,
seeing how the shadow they cast can effect the amount of electricity powering the light, motor and water pump.
