Local Company
We pride ourselves on having our headquarters located in the nation’s first LEED Platinum
Student Union at San Diego State University. We are a local business only 15 miles away
from the Kearny Mesa High School. Our close proximity to the parking structure makes it
easy for us to coordinate the project, materials, deliveries and labor. Local business
interactions is better for the environment and better for the community.
Mission Statement
Aztec Energy’s goal as leader in the green energy community is to help the community to
reduce their cost of operations, help the environment, and serve the community. Our team
has exercises creative, and alternative ways to solve problems. We exemplify this by
overcoming the unique circumstance in which all of San Diego County’s student union
building have been renovated by the end of the first quarter of 2014. Our team of experts
thought it would be most beneficial to serve the community by reaching out to Kearny Mesa
High and providing the School District with a plan to update their Gym, which serves as a
place of congregation for their students. The community as a whole benefits as we are not
only changing out the lights, but we also opened up the door to educating the students
about sustainability and changing the habits of the future generation. It starts not with the
technology, but with the people. This is our mission.
Proposal Outcome
By using our contractor and utilizing our proposed renewable sources, lighting retrofits, and
monitoring equipment, we will continue to save the client energy for decades and continue
to educate the community about their energy consumption habits. We will be updating the
lighting through the use of new Title 24 compliant dimming LED ballasts along with solar
tubes for daylighting capabilities and all it will be wired to the nLight system in the gym for
improved lighting controls. The will reduce total energy consumption by 40%. . In addition,
we would like to implement a PV system that will be able to put the gym into an energy
producer to serve the rest of the high school campus. In keeping up with Title 24
requirements, we are also proposing to install a monitoring system with a display panel to
show and educate the community on their energy consumption behaviors.

Project Summary
Proposed Budget
Our total proposal cost is $307,737 and will have a total payback of 8.9 years.
The Client
The official client is the San Diego Unified School District because Kearny High is a K-12
school under the control of the District, but our interactions with the client and feedback is
received directly from the school staff. Kearny Mesa High is directed by Principal of
Construction Tech Academy, Cheryl Hibbeln, and Principal of Kearny High, Ana Diaz.
Jerry Butkiewicz is on the advisory board and helped to introduce sustainability into the
curriculum at Construction Tech Academy.
When Kearny Mesa was established, it was named after its military base, Camp Kearny.
Camp Kearny was operational from 1917 to 1946. This public high school opened its doors
in 1941, and only undergone slight renovations since. During the 2004-2005 school year,
Kearny High was transformed from a traditional high school into a campus with four
independent and specialized schools, each with an emphasis on fields of study such as
Digital Media and Design, International Business, Construction, and Science and
Technology. This system resembles the different colleges on a typical campus, because
each separate “high school” is completely autonomous and independent of the others and
each has a specialized curriculum specific to their own area of study. The new school
system was founded by Bill and Melinda Gates and the program is funded by the Bill and
Melinda Gates Foundation.
Role of Facility
We propose to retrofit the existing Kearny Mesa
High School gymnasium located at 7651 Wellington
Way in San Diego, California. The gym and its
adjacent spaces within the structure spans 20,130
square feet, and is located in an inner-city setting
within the Kearny Mesa neighborhood. The structure
was built to accommodate student body meetings,
assemblies, and athletic competitions year round. It
is also an emergency shelter for the community in
the case of a disaster. Geographically, it is
surrounded by the Pacific Ocean on the west and
mountains to the east. The location between ocean
and mountain provides a slow, but fairly consistent
stream of cool air.
Figure 1.1-Campus Layout

Project Summary
The gymnasium includes other spaces such as restrooms, a wrestling room, coach offices
and a boy’s locker room. The high school’s alumni has strong sentimental feelings towards
the original gym design. Some of the alumni have kids who now attend the school.
Therefore, all proposed design modifications will maintain a low profile in order to keep the
original image of the building. Aztec Energy plans to implement new systems to improve
functionality of the building while simultaneously enhancing the community’s awareness to
the energy saving benefits through sub-metering. After the retrofit, the structure will have
improved energy efficiency and the original look will be maintained to satisfy the wishes of
the community.
A 3D scanner was used to model the interior spaces of the gymnasium. This allowed Aztec
Energy to provide accurate take offs for the estimate. The model is shown below in figure
1.2.

Energy Use Analysis
Aztec Energy investigated and analyzed the client’s total energy consumption for the
gymnasium to identify ways to conserve energy and save the client money. Energy bills
were made available to Aztec Energy upon special request to the District. Unfortunately,
the metering data received monitored the entire campus aside from a few select buildings.
The main campus meter also monitored the power fed by the current PV panels under a
purchasing agreement located in the parking lot. It was clear that the energy bills were not
going to provide enough detailed information on the building to create a solid baseline,
therefore, it was decided by the team to analyze the lighting system based on
observations and guidance from Nordstrom Christer, he works for the District in the
Auxiliary Services department and he is a LEED AP involved with the most recent lighting
retrofit. With the help of Nordstrom, we were able to figure out how the current controls
were designed in order to make a close approximation of the amount of energy that is
consumed by the Gym. The baseline calculations can be seen in Table 2.1. The campus
metering data is shown on the next page as well.
Table 2.1- Baseline calculations
Aztec Energy
DESIGN- BUILD

Energy Use Analysis
Table 2.2- Energy Bill
The electricity consumption for the entire Kearny High campus uses an
average of 62,615 kWhr per month which is 3 times as much power as the
Gym consumes in a year! This is the justification for ignoring the metering
data for our baseline.
Heating
The team was advised during the first site walk that the building contains a
heater room, but the boiler inside is used to heat the offices in the adjacent
buildings, not the gym (Figure 2.1). The hot water tank has been insulated
fairly well, but certain sections of the pipes are missing insulation.
Nordstrom mentioned that the pumps for this tank uses a VFD at 5%
speed which suggests that the hot water is used as radiant heat for the
offices. There are some possible upgrades to this system, but none will be
implemented as this campus serves as an emergency shelter so reliability Figure 2.1-Hot water tank
as well as maintainability takes a higher priority over energy efficiency.
Aztec Energy

11
Energy Use Analysis
There are separate gas line heaters located
in the building as seen in figure 2.2. The
school’s staff stated that, “those heaters
haven’t been used in a long time”. This is a
reasonable statement since Kearny Mesa’s
semi-arid climate and close proximity to the
ocean provides sufficient temperature
throughout the year.
Figure 2.2-Locker room heater
Ventillation
Ventillation in the building is almost
non-existent. There are ceiling vents
in place as well as some active
ventilation, but the school has been
relying on 4 large fans to push air
through the building when it gets too
hot.
Figure 2.3-Fan
ENERGY STAR Benchmarking
The following reports were generated by the EPA Benchmarking tool. The first report is
based on the entire campus in order to obtain a performance score to compare against
other schools. This was to done due to the fact that the Gym’s facility type is not available
for comparison against other facilities from EnergyStar. The second report includes the
specific building in question in order to provide an EUI score. We have no specific
metering data available so the report is only based on the accuracy of our assessment on
the Gym.

Observation and Recommendations
Ventilation
This building provides a unique challenge to save money. There is already some passive
ventilation currently being used in the structure through the roof and vents on the walls. Any
fresh air will usually come from a natural breeze or from the portable fans that are temporarily
plugged in. What is missing from the gym is comfort. Students complained about the
consistently high ambient temperature. When measured from a thermometer, the temperature
was consistently above 75 degrees Fahrenheit. Without moving air, this is not a suitable
temperature to be in during strenuous activity. Aztec Energy proposes to install two X2.0
Powerfoil fans from Big Ass Fans. Our team contacted Big Ass Fans to determine the best
location and sizes to provide adequate cooling. We recommend 2 of them to mounted at 20
feet above the floor. See the cost estimations for included costs for time and material. See
figure 2.5 below for location details:

Day Lighting
The current lighting system requires a key to turn on a number of fluorescent lights
without any way to zone the lights individually. There is also no advantages taken to
consider the use of daylight from the windows. There were some luminaires that
appeared to be attached to the motion sensors, but since the whole gym is one zone,
the individual rooms light up regardless of its occupancy. So they remained on behind
locked doors and closets. To improve daylight capability in the gym, Aztec Energy
proposes to install solartubes that mount into the ceiling. This is a crucial component for
the retrofit as there is currently not enough ambient light to take advantage of inside the
gym. Skylights are not an option as they would require a large hole in the ceiling which
would introduce issues with structural integrity. Our team made an in-depth analysis on
the lighting power provided by the current windows in the locker room and the wrestling
room, and also made a study of the potential daylight available if the solartubes were
installed. The tool used was an excel lighting calculator provided by PG&E. Only the
formula was changed from BTU/(hr * SF) to kW based on the area of the windows or
solartubes, percentage of transmission through the material, and a conversion factor for
energy units. The results are shown below:

Energy Use Analysis
The result if this analysis is that we have sufficient light that is available during the day. The
Wrestling room is usually used in the morning or afternoon and it sees the most directly
sunlight during these times so it can take advantage of that light. The locker rooms are
used throughout the day as PE class goes on and as the locker rooms get used for the
sports teams. The light intensity doesn’t pick up until the afternoon when the light is able to
reflect off the white roof. A lot of the light available in the locker rooms is ambient lighting
which is good since there is less need for window treatments. The daylight sensors will still
be able to be used in this room. Certain areas are blocked off from the daylight, but there is
still some light during the peak hours. Lastly, the gym’s solar tubes are mounted on the roof
in a vertical orientation so the gains from daylighting is most prominent during the
afternoon, but also provides plenty of light as early as 9:30AM and as late as 4:00PM. With
a new controls system, daylighting sensors, and high efficient dimmable lights, we can take
advantage of the daylight and be able to turn off the lights completely during peak hours of
the day, and slowly add more power to the lights as the daylight starts to drop off. Based
on this analysis energy savings Aztec Energy proposes will be reduced under baseline by
42% as shown in table 2.3.

Brief Summary
Aztec Energy is proposing to retrofit the lighting for the gymnasium and adjacent spaces at
Kearny High School. Given existing conditions, changing the lighting from fluorescent to
LED, adding occupancy sensors in all of the spaces along with daylight controls and
dimming, will make the gymnasium more energy efficient. With this retrofit Aztec Energy is
expecting over 40% in savings! A breakdown of the existing fixtures and and proposed
lighting is included in table 3.1.

Lighting
Existing Conditions
The gymnasium lights are mounted at inconsistent heights, which makes lighting
distribution uneven. The average foot-candles differ at various locations around the gym,
ranging from 25 to a maximum of 28 foot-candles.
There are (36) 8-lamp fluorescent high bay light fixtures, which use a lot of power but do
not provide sufficient lighting or at least 50 foot candles for the gymnasium area. The gym
area also has (4) 2-lamp fluorescent high bay safety fixtures that are always on. There are
(6) 2-lamp fluorescent emergency fixtures that are never on, however they are battery
controlled fixtures in case of a power outage. The rest of the areas in the gymnasium,
along with the bathrooms, lockers, and offices, have 2-lamp fluorescent fixtures that are
switched and do not allow dimming. Many rooms have windows which permit natural
lighting and the lights should be off during the day. Also, Aztec Energy found about 6
fixtures that do not serve any purpose in the building.
Figure 3.1-Existing Lighting in Gymnasium
Proposed Lighting
The most energy efficient light fixture is the one that doesn’t require energy. That is why
Aztec Energy is proposing SkyVault M74 solar tubes which will deliver natural light into the
gym and help to reduce energy consumption by dimming the high bay lighting. Aztec
Energy is proposing a total of 16 solar tubes to achieve an average of approximately 23
foot candles, which is perfect for regular school classes. Research performed at this
location indicated the following lumens data: average – 16,732 (March 21st, 9am); Max. –
35,140 (June 21st, noon); Min. – 4,483 (Dec. 21st, 3pm). The photometrics for the solar
tubes is included in appendix A.

Lighting
The (36) 8-lamp fluorescent high bay light fixtures will be replaced with just 12 I-beam LED
high bay luminaries equivalent to about approximately 48,000 nominal lumens per fixture.
Instead of replacing one-for-one, Aztec Energy did research and is proposing to upsize the
lights to get greater output and eliminate 24 fixtures. To evenly distribute the lighting, Aztec
Energy is proposing to mount all 12 fixtures at a 22’ elevation. Figure 3.2 below shows the
photometrics for the 12 I-beam LED luminaries.

The (4) 2-lamp fluorescent safety fixtures will be replaced one-for-one with I-beam LED
high bay luminaries equivalent to approximately 9,000 nominal lumens per fixture. This
LED fixture will give out better light and provide more lumens than the one currently
installed. Since these are safety fixtures, and are always kept on, Aztec Energy will ensure
that the replacement safety fixtures will continue to be kept on. Please refer to the
proposed lighting/sensors layout for fixture type.
The (6) 2-lamp fluorescent emergency fixtures are battery-controlled and are never on.
The only instance these fixtures would be on, is during a power outage. These emergency
fixtures do not consume any energy, therefore Aztec Energy will not replace these fixtures.
The current (89) 2-lamp fluorescent fixtures in adjacent rooms will be replaced with only
(61) STL LED luminaires. There are several reasons Aztec Energy chose these fixtures.
One reason is they have longer life, which reduces maintenance. The next reason is they
are highly energy efficient and sustainable. Another reason these fixtures combine digital
LED lighting and controls technologies with high-performance. The proposed lighting
layout and fixture types are included in appendix B.
Dimming Controls, Occupancy Sensors, and Photocell Sensors
The gymnasium will have specialized sensors that include combination dimming and
switching photocell with high/low occupancy operation. These fixture mount sensors are
LSXR family SensorSwitch that can be found on Figure 3.3. Aztec Energy will provide one
sensor per fixture, which will total 12. The adjacent rooms will have occupancy sensors
and all lights will be dimmable. The wrestling room, boys locker room, and several
bathrooms will have daylight controls to offset the natural lighting. Please refer to the
proposed lighting/sensors layout for locations of these sensors.
LSXR
The gymnasium will use natural lighting through solar
tubes and provide more lighting to occupied space,
meeting the foot candle requirement. The adjacent rooms
will also have sufficient lighting and daylight/occupancy
sensors with dimming controls that will reduce energy
consumption. Aztec Energy will also switch out all 4 exit
signs with LED exit sign combo with emergency lights
shown on Figure 3.3. And we will add a missing exit sign
in the boys locker room. This retrofit will save the client
over 40% energy use.

Renewable Energy
Background
A majority of the world's current electricity supply is generated from fossil fuels such as
coal, oil and natural gas, these traditional energy sources face a number of challenges
including rising prices. As a leader in renewable energy, Aztec Energy will be working
with the client to pursue energy performance targets that will increase the production of
renewable energy. Aztec Energy will be analyzing and recommending the best
renewable energy system fit for the site and will accomplish the client’s goal.
Renewable Energy Analysis
One renewable energy option that was analyzed was a wind energy system. It was
determined that a wind energy system would not be feasible for the high school due to
the low wind speeds in the area.
Geothermal
Second renewable option that was analyzed
was installing a geothermal heat pump. Due to
the cost to of the equipment, it made geothermal
cost-prohibitive to the client. The other two
forms of geothermal, direct use or electricity
generation are also cost-prohibitive due to them
being used for larger scale grid system. Aztec
Energy did reference NREL map for best sites
for geothermal. Figure 4.1 shows a simple
geothermal heat pump diagram. Geothermal is
not an ideal source of energy and will not be
recommended to the client.

Renewable Energy
Solar
The last type of renewable energy that was analyze is solar. Aztec Energy recommends
that the best form of renewable energy is solar energy. Data gather from SunCalc.com
shows that Kearny High School stands in a great location. Figure 4.2 shows the sun
position and the sunlight phases that the school is getting on a regular day.The gymnasium
is facing the south side meaning that this has a great potential to produce a lot of electricity
throughout the day. For the most part San Diego is always sunny. From the figure below
Kearny High is getting approximate 8-10 hours of sunshine per day. A photovoltaic system
will be recommended to take advantage of all the sun that the school is getting.
Figure 4.2-Solar calculations
Placement of Photovoltaic System
The gymnasium has a very unique architectural look to
it and has been around since 1941. Due to this the
dome like roof cannot be modified, by request of the
school district. This means that no cutting or additions
to the existing roof. Accepting the school’s request
Aztec Energy is proposing to install a photovoltaic
system adjacent to it. The photovoltaic system will be
directly above the locker rooms/office such as shown in
figure 4.3 indicated in red.The total square footage of
that area is approximate 2800 SF. Aztec Energy will
be installing 80 solar panels to the roof, a layout of the Figure 4.3-Proposed location of PV System
solar panels array can be shown in figure 4.4. The
electrical room is almost directly below, making this a
great location to connect all of our electrical
components. Aztec Energy found this to be the best
location for a photovoltaic system that will reduce the
initial cost and satisfy the client’s request.

Renewable Energy
Mounting System
The proposed location of the solar panels will be on top of
the adjacent building of the gymnasium. The roof is flat
and has a few exhaust fans and a HVAC line that runs
through to other roofs. The few exhaust that are in the roof
and the HVAC line will not be in the way of the solar
arrays. The layout on figure 4.4 shows the location of the
solar panels and how the fans and the HVAC line will not
be affected. The solar panel arrays will be mounted on top
of the roof; they will be place at a 17 degree angle.
Although 31 degrees is the standard placement for solar
panels Aztec Energy will be placing the solar panels at a
17 degree angle. This will be done in order to received the
right amount of power for the space. There is no major tilt
that has to be accounted for due to the fact that they are
located facing south.
Figure 4.4-PV Layout
Solar Panel Selection
Solar technology has evolved over time and has progressively got more efficient and
affordable; pricing is included in table 4.1. The solar panels that Aztec Energy is proposing
to install are top of the line SunPower X-21 Series 345 Watt monocrystalline solar panels
(figure 4.5). The panels produce 21% more energy per rated watt than other conventional
solar panels. As one can see from figure 4.7 the X-21 Series will be a better investment
over the years compared to other conventional panels. A variety of solar panels such as
Sharp,Solar World, Astronergy or Suniva were considered, but the best option is SunPower
which maintains the most efficient output over its lifetime. SunPower also offers the best
combined power and product warranty compared to other conventional solar panels on the
market such as shown figure 4.6.

Inverters
Aztec Energy will be installing just one central inverter for the entire solar panel system.
Aztec Energy first thought about including individual AC microinverters for each solar
panel, but it would result higher initial cost. Microinverters are best fit for areas that have
an ease of access under the panels because it is expensive to access them safely if they
need future service. Although there can be benefits to microinverters, Aztec Energy is
proposing high producing panels that can have the same amount of benefits as installing
a microinverter for each panel.

Return on Investment
Figure 4.9 shows the electricity the solar panels will produce per month. The total annual
system production is 42,683 kWh per year. This is approximately 4.5 times the energy that the
gymnasium requires to operate. Therefore, our combined proposed lighting and solar retrofits
will put the Gym into an energy producer. This retrofit will not only pay for itself, but it will help
to offset the enrgy consumption of the rest of the campus. Aztec Energy educating the
students and teachers at the school the importance of conserving electricity.

Image of The Client
As mentioned before, Kearny High is departmentalized into separate schools with their
specific area of study. The Construction Technology Academy preaches energy conservation
awareness. For example, students go on field trips to places like the San Diego Gas & Electric
innovation center to get educated on sustainability. Aztec Energy will be helping the student
body be aware of the school's energy consumption by installing a monitoring system with a
graphical a display of the energy savings provided by the building. Students will also be able
to monitor how much energy the solar panels are producing. This will coincide with the
sustainability concepts the students are being taught in class, thus reinforcing the impact that
building improvements provide with tangible data.

Sub Metering - Overview
Benefits of Sub Metering
Sub metering is beneficial for multiple reasons, first it allows a benchmark to be set so
facilities managers understand energy draws on their building. Second, it allows for real
time accurate data to be collected thus making reduction in peak demand charge a viable
option. Third, the actual return on investment can be easily realized and this more detailed
data will help to spur other energy efficient projects across the campus and reduce energy
bills for the school. Forth, it will allow the client to portray their energy usage to student
which will be a great educational tool for the school.
Installation of sub meters can easily be integrated to the retrofit for the facility. The meters
will tie in to the feed in to the gymnasium lighting and plug loads and will be located on the
electrical room. A meter will also be installed on the solar array to monitor the energy output
of the system. All sub meters will be located in the electrical room.
Monitoring Areas
The gym building will be divided into several different monitoring areas; by doing this it allow
facilities staff to understand the diverse space within the gym.
The proposed system for sub metering the separate systems in the gymnasium includes:
1. Gymnasium, wrestling room, bathrooms and kitchen
2. Boys/girls locker rooms and coaches offices
3. Photo voltaic array
Student Awareness
Sub metering allows an opportunity to educated students about their energy consumption.
By installing an energy dashboard at the entrance of the gym it will allow students to see the
actual cost of energy and give them a better understanding of what it costs to use electricity.
This dashboard can also be used in the Green Tech class in Construction Tech Academy
located at Kearny High. This class is covers green construction and energy use. The class
is currently in a competition with other schools to reduce the energy consumption and useful
sub meters can give them a much better understanding of where they can conserve energy.

Construction Schedule
Duration
The duration of this project is from June 16, 2014 - August 14,
2014. The two month duration is possible due to phasing, which
also allows construction activities to be completed during the
summer months when traffic on campus is reduced.
Phasing
The retrofit of the gym will be broken into 3 general work areas.
The gymnasium, locker rooms and photo voltaic array will be
stacked in order to reduce the duration.
Critical Path
The critical path for this project runs through construction of the
gymnasium. There are several days of float available in the
locker room and PV array which will allow Aztec Energy to shift
crews if needed in order to remain on schedule and turn over the
gymnasium prior to the 2014/2015 school year.
Student Safety
The construction duration will be completed during summer
months when traffic is reduced on campus. This will allow us to
ensure student safety by not exposing them to construction
traffic. The site will be fully fenced preventing unauthorized
personnel from entering the site. Flaggers will also be used to
prevent traffic delays, and assist students in crossing the street
to the adjacent parking lot. This is a vital tool used to keeping
students and staff safe during construction. A preliminary site
logistics plan is shown in figure 5.4.
Reduced Cost
By working during the summer it will allow Aztec Energy to avoid
overtime and premium pay, reducing cost to Kearny High.
Workers will also be able to drive equipment on campus without
being uninterrupted by classes, which will allow for higher
productivities making the short construction duration possible.
Direct access to the gym via the adjacent parking lot will provide
the site with lay-down and space for construction trailers. Close
proximity to the project reduces material handling time. Material
handling is the largest source of non productive time in
construction.
A detailed schedule is included in figure 5.3.

Financial Analysis
Project Funding
The total cost of this project was an estimated $307,737. Aztec Energy identified several
options for funding the renovations to the gymnasium. NECA Works was utilized to
analyze the costs, ROI, incentives and rebates for solar and lighting for the gymnasium.
The city of Kearny Mesa receives electricity from SDG&E utility company, which qualifies
them for SDG&E related rebates and financing. For the lighting retrofit, Funding will be
received from the use rebates from SDG&E “Energy Efficiency Business Rebates
Lighting Catalog”. The catalog lists fixtures and controls along with $/unit. After
calculations, the total we will receive in rebates is $1360. This will bring our project total
down to $306,377.
Proposition 39
Proposition 39 indicates that multi-state companies have to pay taxes based on sales in
California (Single Sales Tax). By doing so, California will generate $1 billion in new tax
revenue each year, part of which will be used towards clean energy and energy
efficiency projects. The majority of funding is based off of average daily attendance
(ADA). Although funding is granted per School District, the maximum amount of money
allowed to be allocated to one individual school is $130,000. Aztec energy is confident
the maximum amount will be received to fund this project, due to Kearny High's ADA of
1,735. This will bring our project total down to $176,377.
Solar
The solar array will output 72,540
42,684 kW or $18,135 per year as shown in Appendix F. This
will provide a payback of approximately 1.2 years with incentives. The California Solar
Initiative Standard PV program will provide $4,865.80 per year after installment for 10
years. Benefits from the California Solar Initiative will bring the project total to $127,719.
Solatubes, has decided to donate 5 of the 16 solar tubes in order to market their product.
This will save the project roughly $5000. Additionally, this reduces the total project cost to
$122,719.
Financing
Aztec Energy will apply for SDG&E On-Bill Financing program to cover the additional
project cost; this program offers 0% financing and is open to all non-residential customers
who had an active account with SDG&E for the past two years. The maximum amount of
incentive is $1,000,000 with ten year max payback, and we will be apply just for the
remaining $122,719.
Lighting Costs
As shown in Appendix the lighting retrofit will save approximately 65,871 kW or $16,468
per year with a payback of 4.4 years with incentives and rebates. With this savings the
total project remaining cost of $122,719 will be paid back in roughly 7.5 years. This 7.5
years includes miscellaneous costs for the project not covered by incentives. After the
payback period is complete the additional yearly savings will be realized by the district.
The ROI for lighting is included in appendix E.

Outreach
As part of our mission to reach out to other students at all levels, we create a positive pathway for
the future in both renewable energy and furthering careers in electrical contracting. This year we
decided to blaze a new path by including a 9th grade class from our local Kearny High School and
Construction Tech Academy. Our goal was to enhance their studies of renewable energy and
develop a partnership by including the class input. In addition, we were able to act as mentors
representing the college path. We were surprised to understand that many students had not
considered college nor understood the vast possibilities in the study of construction management
and engineering. We were also pleased to see young women now considering this career. By
engaging the class in our site walk and providing a forum for a discussion of our project and all
available renewable technologies, we were able to enlighten an already bright group of students to
new energy solutions and expand their vision of the future. In turn, Aztec Energy was rewarded
with a long term partnership with a local high school, mentoring students towards a college path
and into the electrical contracting industry. This will now be included in our mission. San Diego
State University is also a proud supporter of many groups and clubs that inform students of the
importance of the environment and how to be environmentally conscious. The following are a few
groups that contribute to the amazing family of clubs at SDSU:
NECA Student Chapter
This chapter is comprised of mainly Construction, Electrical, and
Mechanical Engineering but all other majors are welcome. It
provides students with a greater familiarization with the electrical
construction industry, promotes professionalism and prepares the
students land an internship with an electrical contractor.
Associated Student Green Love
This organization works very hard to embrace sustainable practices in all facilities at San Diego
State. Their mission is to pave the way for a full-scale sustainable movement by and for SDSU
and the community. They assist in measuring and improving operations and encourage student
organizations and residents to adopt sustainable habits. Assist SDSU in becoming a model
University in sustainability by measurably improving operations to meet the highest standard of
sustainability that is feasible.
http://as.sdsu.edu/greenlove/
Enviro-Business Society
This is a non-profit environmental advocacy organization at SDSU that offers all students of all
majors of a unique and beneficial way to make a positive and environmental impact on campus,
in the community, and in business. This society promotes modern business practices that
maximize profit and a sustainable future.
http://meldi.snre.umich.edu/node/24797
USGBC Student Chapter
This chapter’s mission is to create an entire Green University by making all existing buildings on
campus to be LEED certified and bring awareness to all students on campus. This year the NECA
student chapter and Green Energy Challenge team members conducted joint meetings with this
organization to improve the effectiveness of meetings and combine the memberships of two
organization that have similar goals.

Outreach
Power Save Campus
Green Campus promotes their ideas and projects by holding
various events, audits and awareness campaigns to educate
students, faculty, and staff on how they can save energy. They
aim to reduce the amount of energy used on campus and to
promote the green workforce.
http://www.sdsupowersave.org/
Greenfest
GreenFest is sponsored by the SDSU’s associated
students and their objective is to engage the campus
community through social and interactive programs in
an effort to educate them on the important of living a
sustainable lifestyle and to promote sustainable
practices. Every year they have activities for an entire
week which consist of bike brunch, herb garden
expo, and a variety of student organization
competitions to educate the community.
http://www.as.sdsu.edu/greenfest/
Method 1: Bring Awareness to Campus
Aztec Energy plans to improve energy conservation awareness on campus by creating brochures and
passing them to students on campus. We inform our community of the importance of our chapter and of
ways in which they can help out their communities. Our goal is to show that a little act by each individual
can greatly impact the community. We want to show students easy but not so obvious ways to conserve
energy.

Outreach
Method 2: Green Orientation
Every year San Diego State University
holds the Explore SDSU Open House in
which incoming students are invited to
come and meet all the clubs on campus.
This is to get a feeling on what they might
want to join in their future career in college.
Our chapter attends every year and
informs students of what the NECA student
chapter consists of. We also recruit people
to join our chapter in order to get involved
at school and with their future. We want to
implement a mandatory orientation in
which all incoming freshmen would go
through a Green Practice Orientation. This
can be a joint effort by all organizations on
campus in order to teach students how
they can adopt sustainable habits. This is
a great opportunity for all organizations of
different majors to work together with a
common goal to create an orientation that
will capture and inspire incoming students.
Our team can help be the spark to the
movement and will plant the seed that
Associated Students will follow through
with.

Method 3:Lecture to Students and Other Groups
When it comes to spreading the word and
awareness our team is determined to reach out to
as many people that will hear it. As a student
organization we like to inform other students and
organizations of our efforts. Aztec Energy spreads
the importance of the electrical construction
industry, local NECA chapter events, and
sustainable habits in general. This year we have
decided to help out Construction Tech Academy
at Kearny High School and raise energy
awareness among the students. Our goal was to
educate the students on the importance of energy
and what they can do in order to save energy at
school and in their households. The students
were also educated on what the efforts of Aztec
Energy are in helping their school retrofit their
gymnasium. An open
questionnaire was given to the student in order for
them to ask any questions that they had about
energy conservation, or even just their future with
college. Aztec Energy's goal is to help the
students understand the importance of energy
and to help guide them into the correct path when
it is time for college.

Method 4: Social Media
As social networking is becoming increasingly important in
our society, our team has been taking note. We have been
informing communities in San Diego through these social
networks. For example, we like to take advantage of the most
popular social media; Facebook. We keep our followers
informed on upcoming events and news via our Facebook
page. Through daily posts, we spread awareness across
campus and encourage students to be sustainable by
showing them examples of how to reduce energy. In addition
it is a great way to recruit new members. QR Code has been
a great contributor to our awareness because of the
popularity of smart phones. Anyone is able to download an
application and they are able to scan the barcode right away.
This takes them to our website. It is a very easy and effective
way to reach out to new members. Please try it for yourself!

Testing and Feedback
Testing, feedback, and Implementation of plan completed
Currently, NECA SDSU’s proposal to the client has not yet been implemented. In dealing
with a K-12 school, there are many steps to be taken before the School District will give the
approval to use the whole plan or parts of the plan. Our team has already taken some of the
initial steps by gaining recognition and support from members of the school. Specifically,
our team has been in direct contact with the principal of the school, members of SDGE who
are involved with the school’s operations, and members of the School District’s
sustainability efforts who have been involved with the school’s sustainability upgrades for
the last 16 years. The people who can help us make a difference on this high school
campus already gave us their support and have joined the discussion about our proposal.
Nordstrom Christer, who helped to design the current lighting control system, commented
that one day when the funding is available that the School District would like to upgrade to
LED fixtures, but it is preferred to do so when the funding is made available from either prop
39 or when the price of LEDs has dropped down low enough. We’ve been praised for
creating a plan that is compliant with the new 2014 Title 24 energy codes that is planned to
be effective in July. Furthermore, our team has created a new partnership with the school in
which our team is expected to come back in the following years to help mentor the high
school students. By staying connected to the school’s sustainability curriculum, we are
guaranteed to keep the discussion open about future retrofits.

Local NECA Chapter Interaction
Aztec Energy would like to thank the following individuals and organizations that have been
our mentors for this competition. We could not have been as successful without the
guidance and patience of the following:
The NECA Student Chapter would not exist if it were not for the local NECA chapter. We
have worked very closely with the local chapter in many ways from attending training
sessions to presenting at the monthly chapter meetings. In addition we were able to interact
with local large contractors such as Dynalectric, Chula Vista Electric, and HMT Electric. This
was a great opportunity in where we got to learn from the experts. Aztec Energy was able to
attend "Understanding Rates, Bills and Benchmarking" learning session which was done by
David M. Wylie from ASWB Engineering. Scot Hemingway of Dynalectric came with us to the
Kearny High School gymnasium and consulted us on lighting, helped identify controls
system, and answered all of our questions. Aztec Energy also got to tour SDG&E Innovation
Center, where we got many great ideas such as solar tubes and Big Ass Fans for the
gymnasium. Possibly the most beneficial to our members was the opportunity for internships
thanks to our local NECA chapter. Because of the quality of work that our members
showed, students were offered internships.This is the most rewarding benefit that the local
NECA chapter provided for us, aside from the experience and knowledge that enabled us to
secure these positions. Our experiences with the local chapter only strengthen our views of
this great organization. We all plan to continue our involvement and help give back just like
the chapter has done for us.
