Dear Mr. Brian Ho,
Husky Electric appreciates the opportunity to present our formal proposal for an energy efficient
upgrade of the Central Parking Garage. Our team intends to deliver the project and complete the
scope of work in 42 calendar days beginning June 14, 2013, and achieve project completion by
August 12, 2013. The initial cost of the project is $423,180. We have identified $227,115 in
incentives and rebates that will reduce the cost to the University of Washington to $196,065.
Projected annual savings indicate this project will earn a return on investment in 1.7 years.
Husky Electric’s scope of work includes:
 A complete retrofit of the lighting system
 Installation of electrical vehicle charging stations
 A ventilation system upgrade
 Implementation of a photovoltaic energy system
Any work within the proposal that is not self-performed will be subcontracted and managed by
Husky Electric. Additionally, Husky Electric aims to work with the UW to increase campus energy
awareness by involving and improving upon current sustainability efforts.
Husky Electric understands UW’s dedication to environmental sustainability without sacrificing
the historical integrity of the campus. We are proud to be given the opportunity to assist the UW
in this commitment. Our team is confident that our proposal will not only meet your
requirements, but also surpass expectations.
Husky Electric would like to apply a technical analysis score adjustments as follows:
Lighting retrofit proposal x 1.4
Energy Audit/Retrofit Proposal x 1.0
PV and Wind Proposal x 0.6
We look forward to providing the electrical work and solution management for this project.
Sincerely,
Brandon Burr

Summary of Project and Client
The University of Washington has provided Husky Electric with many resources and an excellent
opportunity by supporting the NECA Student chapter evaluation of the Central Parking Garage
for “The Green Energy Challenge.” Although the Central Parking Garage and the above Red
Square are seen as iconic structures on campus, it has potential to meet the rising sustainable
standards of the university.
Originally constructed in 1972, the Central Parking Garage is a 416,390 sq. ft. underground
parking garage located in the center of the campus under other iconic buildings including Meany
Hall, Kane Hall, Odegaard Library, and Suzzallo Library. The parking garage features three
separate vehicle entrances and a total of 984 parking stalls on three floors. There are four stairs
that access Odegaard Library, Kane Hall, Meany Hall, and outside to the west side of the
structure. The Central Parking Garage’s outdated electrical systems provide the University of
Washington and Husky Electric the opportunity to work together to save money and reduce the
university’s energy consumption.
Husky Electric has two main points of contact for the retrofit of the Central Parking Garage:
Brian Ho, the Parking Facilities and Special Events Manager, and John Shaheen, Assistant
Director of UW Transportation Services. Also we have worked with the Capital Projects Office,
which is responsible for developing and overseeing most projects on the University of
Washington campus. These points of contact emphasized the importance of financial acuity and
safety on campus during the development of this proposal.
Striving to be a leader in sustainability, the University of Washington is committed to
environmental responsibility. Many of the new construction projects and renovations are
required to meet or exceed a LEED Gold rating. The University of Washington actively works to
become a green campus through a multi-faceted approach. Recycling, composting, and
sustainable dining programs have all been recently implemented around campus. Additionally,
the University of Washington has taken serious efforts to raise awareness of these efforts to
encourage others to follow.
The Central Parking Garage has long been recognized as a building in need of renovation.
Upgrading the Central Parking Garage presents a unique opportunity to further the University of
Washington’s green aspirations while preserving its historical roots. This renovation will further
exemplify the university’s commitment to the environment.

HVAC Existing Conditions
The Central Plaza Parking Garage is open all hours of the day and therefore requires continuous
operation at varying levels throughout the day. The exhaust system for Central Plaza Parking
Garage works mainly through the use of a plenum for each mechanical room. These plenums are
large open areas that act as a vacuum to allow the air to be removed from the garage. Through
suction, the air is pulled through the plenum and up the exhaust vent, which also pulls in air
through the intakes. This large vacuum works to provide air to all parts of the garage. This
system uses eight fans located in two separate mechanical rooms to exhaust the garage.



East Fan Room: (4) 40 HP fans that discharge vertically out of three brick stacks in Red
Square
West Fan Room: (4) 30 HP fans that discharge up sloping shaft toward 15th Ave NE
VFD’s are currently installed on all exhaust fans allowing “soft” starts and stops reducing
power surge losses
Currently the garage requires no cooling because of two factors. First, the garage being located
underground helps maintain a consistent temperature. Second, the buildings located around the
garage are exhausted into the garage further regulating the temperature of the garage.

Proposed HVAC Retrofit
Husky Electric proposes to adjust the exhaust fan schedule on weekends, summer break,
holidays, and breaks when the utilization of the garage is down. With a very low initial
investment, the schedule can be adjusted and the energy usage will decrease a substantial
amount. For full details and cost analysis see the Ventilation System section.
Lighting Existing Conditions
The Central Plaza Parking Garage currently uses 1,717 4-foot T-8 32 watt fluorescent lamps with
electronic ballasts. Near the 3 garage entrances, cold weather ballasts are used. These fixtures
were installed in 1996. The lighting is designated to 4 main control panels; A-1, A-2, A-3 and an
emergency panel. Some light fixtures remain deactivated from a prior lighting renovation, but all
other fixtures are turned on all hours of the day. The garage is currently unpainted concrete
other than a few columns for safety.

Proposed Lighting Retrofit
Husky Electric will replace the current T-8 fluorescent fixtures with much more efficient LED
fixtures. This replacement also allows us to install much fewer fixtures and still meet the same
lighting requirements for the garage. This option will have a short payback period due to the cost
savings due to the lower energy use from the lower amount of fixtures in the garage. For detailed
cost analysis see the Lighting Retrofit section.

Lighting Retrofit
New System Design
To provide a design that meets the requests of our owner, safety requirements, local codes and
provides a significant energy reduction and short payback period we focus on six characteristics.
Our main criterion of analysis included:
 Safety
 Energy consumption
 Future costs



Life Expectancy
Maintenance
Controls
In this design we analyzed the installation of new fixture types, the use of occupancy sensors and
the addition of white – reflective paint to the garage. Results from this analysis provide us with a
retrofit design consisting of fixture replacement and occupancy sensor utilization.

Fixture Replacement
The QLP 32G2 LED lamp with the PX10 Proximo Programmable
Occupancy Detector is our proposed fixture for the garage. With
the use of this lamp, we can reduce the fixture count by 1,492
fixtures and the energy consumption by 70.4%.
Our power consumption from lighting will decrease from 481,309
kWh per year to 142,700.4 kWh per year with the installation of the QLP LED fixtures. The
current lighting system is 50.5% of the total energy consumption for the garage and with a
retrofit will decrease to only 26%.

QLP 32G2 LED Fixture
This particular fixture includes a programmable occupancy detector that dims the light when
motion is undetected. This dimming feature reduces the light output by an additional 20% resulting in extended energy savings. This device is mounted with the lamp and
provides 360˚ range of detection for a radius of 25 feet when mounted 9 feet
high. This device also detects ambient light and ensures that excessive light is not
distributed when daylight is detected. For commissioning and control a wireless
remote is provided to program and update the device. This is a major factor in
the decision to use this fixture. Currently facilities management is struggling to
keep up on maintenance in the garage – thus having a wireless device and simple programming
strategy will be crucial in the new design of the garage.
This fixture comes with a mounting kit and will be mounted on the underside of the beams at a
height of 9 feet. The current fixtures are mounted between the beams – casting shadows through
the space. The new mounting location will pair with the symmetrical light distribution pattern of
the device and better distribute light throughout the garage. This mounting location also
provides the occupancy detectors optimal range and minimal interruption to the sensor.

Light Output
Foot-Candle Measurements
Using the Extech Easy View 30 Light Meter, we measured the current foot-candles throughout
the garage. Per the Seattle Energy code, 4.5 foot-candles are required in parking garage spaces.
Since the garage is under the policies of the University of Washington, we have been advised that
exceeding the minimum requirements is recommended and encouraged for safety. This garage is
open and operating 24 hours a day, year round and completely underground – allowing for very
minimal natural light near the entrances and a heightened emphasis on safety precautions. With
the QLP 32G2 LED fixture from Quality Lighting, we have met the requirement of 4.5 footcandles, exceeding it in the vast majority of the garage. This fixture provides a better distribution
of light, higher levels of lighting and increased safety in the garage. Please see Figure 7 below and
Figure 8 on the following page to compare the differences in foot-candles in regions of the
garage.
Figure 7. Existing Foot-Candle
Measurements
In our analysis of existing foot-candles, we
measured 27 locations on the lower level
and found that the garage had sufficient
lighting to meet code requirements. The
minimum foot-candles measured were 6 fc
at the Southwest Corner Ramp, and the
maximum measured were 16 fc near the
Southwest corner entrance during the
afternoon.
Figure 8. Proposed Foot-Candle
Measurements
Based on our foot-candle measurements
and the safety codes of the University of
Washington and Seattle, we have selected
a lighting plan that meets the minimum
foot-candles required in a parking garage
and provides comparable levels of lighting
in the garage.

Fluorescent Lamp Disposal
Since January 1st, 2013 the City of Seattle prohibits the disposal of
fluorescent bulbs/tubes from any commercial customer in the municipal
solid waste or at the Seattle transfer stations. (Seattle Municipal Code
21.36.025 – Unlawful Disposal)
As a way of continuing our efforts to go green, we have prepared a plan to recycle all 1,717
fluorescent bulbs removed from the garage through Eco Lights – a fluorescent lamp recycling
company conveniently located 15 minutes away from the campus.
Our magnitude of disposal will require 12 4-ft. Straight Fluorescent Lamp Large Recycling Kits
from Eco Lights, priced at $89 each. Each kit will accommodate 144 4-foot T8 lamps and includes
a container, heavy duty liner, zip tie, instructions and prepaid return services.
According to the Office of Solid Waste and U.S. Environmental
Protection Agency, a T8 Lamp manufactured in 1996 or prior to 1996
contains 30 milligrams of Mercury. This means that our total lamp
disposal contains 151.51 grams of Mercury. Ensuring that this
mercury does not go to landfills is important to the University and is
crucial to keeping our efforts eco-friendly.

Impacts
Keeping the six key requests of the owner in mind, we have developed a lighting retrofit that
suits the needs of students, faculty and visitors using the garage; provides the owner with a
reduction in costs and maintenance; and utilizes the new LED technology to conserve energy.
Safety – We have ensured that the minimum foot-candle requirements are met and exceeded
and that fixtures will be on during all hours of the day.
Energy Consumption – We have reduced our energy consumption by 70.4% saving the University
$152,374.15 per year.
Future Costs and Life Expectancy – LED fixtures have a remarkable life expectancy and minimal
future costs. Seattle has an average ambient temperature around 50˚F.The table below indicates
that a lamp in this area will last for 24 years when run 24 hours a day, year round. Future costs of
an LED fixture include replacing bulbs every few decades or replacing malfunctioning occupancy
detectors or fixtures as you would with any other fixture.

Electric Vehicle Charging Stations
Charging Station Analysis
Husky Electric has worked with the University of Washington (UW) conducting comprehensive
traffic studies. We have also conducted surveys with the Central Plaza Garage (CPG) users to
assess the demand of electric vehicle (EV) charging stations. The University of Washington
currently has three (3) charging stations on campus that has attracted a small community of EV
users. With experts predicting an increase of EV's to 300,000 that will be driving on the
Washington State roads over the next decade, this community on campus will continue to grow.
Implementation
After analyzing the data and the surveys that were conducted and in combination with the
predicted increase in the number of EV's, Husky Electric believes that there is an opportunity to
begin to increase the number of stations that UW houses on campus. Our team believes that the
CPG is the ideal location to begin this increase in the number of stations.
Our team at Husky Electric has developed a design that fits the image of the owner and will
provide an opportunity to increase the EV user community on campus. We are proposing that
UW has our team furnish and install 4 new charging stations at each of the three (3) entrances to
the parking garage.
Disadvantages
UW Transportation Services have addressed some concerns with our design team that are the
key reasons for why they have not already begun this EV movement including:
 Not a strong market currently for EV's
 Limited number of trips allowed by City of Seattle
 Financial burden
Because the market for EV's is so small currently, the university does not believe that there is a
need to increase the total number of stations on campus. The university is also concerned
because they are limited to 25,000 vehicle trips to campus each day by the City of Seattle. By
installing these stations, it would not help reduce the total number of trips. With the market still
not at a desirable level, UW feels that it would be more of a financial burden on them than a
benefit to the community. However, our team believes that it has developed a strategy to
mitigate the concerns that the university has addressed.
May 10, 2013
17
120 Architecture Hall | University of Washington | Seattle, WA 98105
Advantages
By installing only 12 stations initially, our team believes that this helps alleviate two of the main
concerns that the university addressed above. Our team believes that allocating 12 stations in the
984 stall CPG will not create an issue by reducing the number of stalls for motor vehicles. Our
team has also developed a strategy for UW to create an additional source of revenue by charging
to use the stations and implementing a free voucher program for users that utilize carpooling.

The detailed summary includes assumptions based on historical data collected from the
Mountlake Terrace Park & Ride garage and current electrical rates. Our team is also making the
assumption that each station would receive four (4) hours of use each 24-hour period. Obviously,
as the market for the EV's increases, the return on investment will approach the break-even point
at a faster pace.
In order for UW to ensure that these stations are being utilized, they must market the stations to
the EV user community. They must also promote the voucher program that our team is
developing for those who decide to carpool. This will not only help the university and Seattle
increase its rating of being the 8th Greenest City in the United States (according to Popular
Science), but it will be beneficial for the user to create additional savings as well.

Overview
Husky Electric received two (2) quotes for stations based on two different models. The CT2103
(Level 1 charger) and the CT2023 (Level 2 charger). In order to fit the desires of the owner, Husky
Electric proposes that the CT2023 charging stations be chosen. There is an increased cost with
selecting the CT2023, however, these stations are better suited for the newer EV's that are being
developed.

Alternative Energy Retrofit
Ventilation Overview
In analyzing the existing system, we identified a potential inefficiency. The baseline schedule for
the existing system assumes the same amount of traffic in the structure 365 days per year.
This leads us to believe that the baseline schedule for these fans should be off completely unless
activated by a CO sensor. However this leads to potential safety hazards with the limited amount
of CO sensors in the building. If air in an area of the building were stagnant, there would a greater
possibility of CO sensors failing to detect higher levels of CO in the building.
Proposed Ventilation System
Proposed Solution: Reprograming the ventilation timing system to reduce peak hour ventilation
power from 100% to 50% during weekends, holidays, breaks, and summer quarter.

The current building management system is perfectly capable of having more control over the
baseline exhaust schedule, which eliminates the need for new systems controls. We determined
that we would be able to reduce the baseline schedule for exhaust fans while still maintaining
safe levels of circulation and CO during weekends, spring break, winter break, and holidays
recognized by the University of Washington schedule based on information obtained from
parking services. We determined that the reduction of daily parking permits sold warranted
following reductions.
Breaks (74 Days)
58%
% Drop In Daily Parking Permit Purchases
Summer Quarter (61 Days)
Weekends/Holidays (72Days)
41%
51%
In maximizing the controllability of this system without installing any new equipment, we
minimize the cost of this aspect of work. The only investment would be the reprogramming of
the ventilation system to a 50% fan schedule on those days.
May 10, 2013
21
120 Architecture Hall | University of Washington | Seattle, WA 98105
In the case that an event were to take place during a reduced schedule time period, the existing
carbon monoxide sensors would detect the predetermined level set by the university and turn
the system on to 100% capacity to maintain a safe and healthy environment
Ventilation Alternative:
Installing (2) Cook TCN-B fans and associated ductwork
 Improves cross sectional flow
 Eliminates risk of air stagnation
 Allows baseline schedule for main fans to be “off”
 Additional upfront cost
 Additional electricity to run fans
In looking for alternatives we determined that installing circulation fans would be a feasible
option. Below is a cost estimate of installing a fan on each floor will improve cross sectional flow
which would ensure the effectiveness of the existing CO sensors. This would ensure there would
be no stagnant pockets of air that could potentially not be occupied by a CO sensor. A detailed
payback analysis is as follows.

Renewable Energy Overview
When looking into forms of renewable energy, photovoltaic panels as well as wind turbine
energy were analyzed. Through a cost analysis, wind energy in the Seattle region has proved to
not be as economical as photovoltaic. However in the appendix we have proposed on the most
feasible wind energy system and have provided a payback analysis.
Photovoltaic:
With the Central Plaza Garage being an underground structure, it proved difficult to find
sufficient suitable area for a PV array. Multiple locations were investigated however the best
location we identified was the roof of Odegaard Undergraduate Library. The Odegaard roof
would prove a very effective and economical location for the PV array.

The most feasible system installation includes PV panels, Inverters, and conduit traveling through
the elevator shaft of Odegaard Library, which arrives very close to the electrical room of the
Central Plaza Garage.

Proposed Photovoltaic System
Proposed Solution: 17.28kW Photovoltaic Panel System mounted to the roof of Odegaard
Undergraduate Library consisting of the following.
(64) 270-watt SolarWorld Sunmodule Panel with Unirac Racking System
(1) - Fronius IG Plus 11.4-1 Inverter
(1) - Fronius IG Plus 6.0-1 Inverter
(1) - Web based Monitoring System
The system will consist of
3 rows of panels feeding 2
inverters. A new electrical
panel will be installed in
the electrical room of the
garage in order to handle
the additional feed to the
building. Conduit will be
run from the roof to the
electrical room via the
shared elevator shaft.
Utilizing the 3,158 square
feet of due south sloping
roof area will maximize
the harvesting potential of
this system. Using a Solar Pathfinder, we have determined that the best angle for these panels
for 100% sun exposure is a 34-degree tilt. The slope of these roof surfaces will only result in a
.388% drop from optimal harvesting potential.

Schedule Summary
The schedule for this project is separated into three main scopes of work:
 Renewable Energy System
 Lighting Retrofit
 Electrical Vehicle Charging Station.
Husky Electric scheduled 9 weeks beginning the week following the last week of spring quarter,
so campus activity will be minimal. Major milestones include Notice to Proceed on June 14, 2013,
Substantial Completion on August 09, 2013, and project completion on August 12, 2013.
Overview
This project will follow a zoning sequence to allow for parts of the garage to remain operable
during construction. Our simple, yet efficient schedule breaks the work into five stages:
1. Mobilization
4. Zoning Plan
2. Ventilation Programming 5. Demobilization
3. PV Panels
Stage 1: Mobilization
Crew mobilization and site preparation facilitate project management for the project.
Stage 2: Ventilation Programming
This work will be subcontracted to a controls contractor.
Stage 3: Photovoltaic Panels
This stage is not a part of the zoning plan. The PV Panel installation consists of 4 major steps:
1. Rack Installation
3. Conduit/Wiring
2. Panel Components Installation
4. Finish/Start-up
Stage 4: Zoning Plan
When one zone is under construction, the two other zones will be operational. Temporary walls
and signage will be restaged when moving zones. Zoning applies to lighting and charging stations.
 The interior lighting upgrade consists of 2 major steps:
1. Old Fixture Demolition/Recycle
Parking Available During Zone
2. New Fixture Installation
Build-Out
 The EV Charging Station installation consists of 3 major steps:

Overview
It is the policy of Husky Electric to provide a safe and healthful workplace for its employees that
complies will all the requirements of applicable safety rules and orders on the Central Plaza
Parking Garage Project. Our Experience Modification Rate is an industry low of 0.53 due to our
outstanding lead by example and zero tolerance policies.
The Superintendent is responsible for implementation of the project’s safety program and the
assurance that it is strictly followed.
 Lead by example.
 Correct any unsafe behaviors or unsafe conditions immediately; looking for opportunities
to train employees.
 Perform a daily walk-through of his/her activities, primarily focusing on the identification
and correction of unsafe behaviors.
 Develop hazard analyses with the foreman and crew. Follow up to assure the hazard
analysis is effectively being used in the operation.
 Set expectations of the crews and assure compliance.
 Conduct a monthly Crew Based Safety Observation (CBSO) on an operation other than
their own.

Community Safety
The Central Plaza Parking Garage retrofit takes place on the University of Washington campus
creating necessary additional safety measures. The garage will remain operational throughout
the duration of construction with available parking dictated by the Zoning Plan outlined in the
schedule. To compensate for additional safety requirements, we plan to surround all
construction zones with high-visibility fencing and strategically place project signage at the
garage entrances and construction zones to direct pedestrians safely around construction. Trucks
delivering material to and from the job site will be required to travel at speeds no higher than 15
miles per hour.

Financing Strategies
Husky Electric has designed a very productive PV system and we have decided that it would not
be beneficial for the Central Parking Garage to engage in a solar power purchasing agreement.
Recently Solar Power-Purchasing agreements have grown more popular. In the state of
Washington, they are still relatively new, and there is not much precedent set. Seattle City Light
has a system to buy back excess power generated by PV systems. However, our estimates show
that the Central Parking Garage will not generate more power than is required for the building.
Additionally, the following challenges have confirmed that we will not be negotiating a powerpurchase agreement:
 More complex negotiations and potential higher transaction costs than buying PV system
outright
 Administrative cost of paying two separate electricity bills if system does not meet 100%
of site’s electric load
 Potential increase in property taxes if property value is reassessed
 Fairly limited federal sector experience

To:
Brandon Burr
RE:
Light Swap Event and Energy Awareness Proposal
Mr. Burr,
The Students Expressing Environmental Dedication (SEED) have carefully
reviewed Husky Electric’s proposal for energy awareness through your
involvement with the Smart Grid project as well as the plan for the Light
Swap event. First, we commend you on your involvement with the Smart
Grid project. We agree that this particular program has the potential to
create a lasting change in the consumption behaviors of students. While
social media is a powerful tool to spread information to the University of
Washington’s student body, we believe more interaction in person would
be beneficial to your cause. This would give you the chance to explain all
that you aim to accomplish in your endeavors.
Secondly, we would like to officially accept your proposal to co-host the
Light Swap event in Red Square. We think this is a smart way to inspire
students to make a lasting change to a more energy efficient form of
electricity usage. Perhaps in the future we could hold similar events for
other types of materials and we encourage any ideas you may have on the
subject. I will contact you again within the next few days to figure out the
details of the Light Swap.
We are excited to see your interest in our cause to create energy awareness
on the UW’s campus and we look forward to your further involvement.
Thank you,
SEED

UW Students Propose Central Plaza Parking Garage Renovation
A hardworking team of six Construction Management students are competing in the 5 th
annual Green Energy Challenge national competition sponsored by the National Electrical
Contractors Association (NECA). The competition consists of the selection of a nearby
parking garage and performing an energy audit and design of the power and lighting
systems. The students have chosen to conduct their research on the Central Plaza
Parking Garage, built in 1972 and in need of an electrical retrofit. Team members
Brandon Burr, Matthew Watson, Kali Leachman, Tara Harrington, David Moore and JB
Gibson have conducted thorough
research and developed a smart
and comprehensive plan to
transform the Central Plaza
Parking Garage, familiarly known
as the Odegaard Parking Garage,
into an innovative and energy
efficient
structure.
These
renovations include but are not
limited to upgrading to LED light
fixtures, replacing carbon dioxide
sensors, adding solar panels to the
top of Odegaard, painting the
walls with reflective paint, and
Central Plaza Parking Garage built 1972
installing car charging stations. This
team of students, calling themselves Husky Electric, has teamed up with the UW’s very
own SEED organization and the School of Public Affairs’ pilot Smart Grid project to spread
energy consumption awareness. Make sure to come exchange your old household bulbs
for a new, energy efficient LED bulb at Husky Electric’s Light Swap event in Red Square on
May 18th at noon to support their mission to go green!

Appendix A - Alternatives Considered
HVAC Option 2: Husky Electric also considered the option of installing two Cook TCN-B 20,000
CFM transfer fans to improve the airflow in the garage and allow the CO sensors to be more
accurate. The problem with the current system is that the air will stagnate and there will be
pockets of air that have a much higher concentration of CO. The installation of these fans would
provide a 20% reduction of the required operating time of the exhaust fans. This system
however, would not be as effective as the reprograming of the schedule and with the almost 16
year payback period, it would not be a viable option.

Lighting Option 2: Painting the ceilings was a viable option to consider. Given that white –
reflective paint can increase the light output by up to 517% and reduce the energy
consumption around 20%, we considered using this as a tool to reduce our fixture count.
Following a payback period analysis we determined that using paint in garage would come at
a significant cost in comparison to the amount of energy savings. In the case that we would
have used a newer fluorescent fixture in the garage – the paint would have played a key role
in energy savings. With the efficiency and performance of LED lighting, it would be a minimal
effect due to the high number of light fixtures we are already reducing, causing a larger issue
with safety and full lighting coverage of the garage.

Lighting Option 3: Replacing the existing T8 fixtures with new fluorescent fixtures would
require a 1:1 replacement ratio, resulting in a poor opportunity for energy savings and no real
reduction in future costs. Therefore this option was not practical for our facility. Another LED
fixture considered was the ELG-MR LED fixture from EMCO. This device would result in the same
reduction in fixture count, but did not meet code requirements in all locations of the garage. The
average foot-candle measurement was 6.7 fc, maximum was 12.7 fc and minimum was 2.5 fc.
The EMCO ELG-MR fixtures result in a larger annual savings but due to code requirements and
safety restrictions for the University of Washington the EMCO ELG-MR fixture does not meet the
needs of our owner. The QLP G2 fixture meets all needs of the owner and will be our fixture of
choice.

Wind Power Overview:
The problem with finding a suitable wind energy harvesting system is that most wind turbines
have a required cut-in speed of 7-10 mph. With an average wind speed in Seattle of 7.53 mph
over the past 3 years, concluded that this system would not be viable in Seattle.
If wind energy were to be introduced on the roof of Odegaard Library, a wind turbine system with
an extremely low cut-in speed must be used. Since 7.53 is only the average wind speed in Seattle,
a lower cut in speed is required. Along with lower cut-in speeds, lower energy production and a
longer payback period would be expected.
Most Feasible Wind Turbine System:
Install a Bergey Excel 10kW turbine on the roof of Odegaard Library.

Photovoltaic Alternative:
As an alternative to the Sunmodule Photovoltaic panels, we investigated using locally
manufactured panels and inverters in order to utilize more Washington State renewable energy
incentives.
Renewable energy incentives for Washington State:
 15 cents / kWh for renewable energy
 36 cents / kWh if manufactured in WA
In order to utilize the 36-cent incentive, we investigated locally manufactured panels and
inverters. It became apparent that the technology of these panels was lacking in comparison to
the Sunmodule panels. Locally manufactured panels were also more expensive. This information
combined with the fact that these increased energy incentives expire in 2020, we have
determined that Sunmodule panels would be a better investment.

Due to the increased payback period in addition to the fact that production incentives will
expire in 2020, our recommendation is to use Sunmodule panels with Fronius inverters.
