Executive Summary New Paradigm Group is excited to propose this comprehensive energy analysis for the Milwaukee School of Engineering’s (MSOE) Walter Schroeder Library building. Our initial examination revealed that this specific building consumed an incredible amount of electricity. Approximately 3,408 Mega-watt hours in the last 12 months!

Our team of energy specialists approached the project on three fronts to reduce the Library’s electrical energy consumption. First was to reduce the lighting loads with more efficient fixtures and the addition of lighting controls. Second was to offset the cooling and electric heating operations with a Power Therm system that uses natural gas to fire an absorption chiller, provide domestic hot water, and electricity as a byproduct. Third, we proposed a solar photovoltaic array and wind generator to reduce the electrical demand from the local utility. These efforts will reduce the electrical consumption by 19.9% (Table 3.1).

This detailed proposal by New Paradigm Group includes extensive information, product cut sheets, and full estimations for each of the proposed systems. Included is a construction schedule, financing plan, and potential LEED credits for the system implementations. We also have provided an arch flash analysis for all of the electrical distribution to provide arc flash hazard labels to protect personnel and property.

New Paradigm Group requests a 1.4 multiplier be applied to the lighting and controls analysis, a 1.0 multiplier to the energy use analysis, and a 0.6 multiplier to the renewable systems analysis.

Client Summary For over a hundred years, MSOE has prided themselves on “progressive programs of technical education.” Founded by Oscar Werwath in 1903, MSOE continues to focus on providing students with an educational experience in engineering, construction management, nursing, and business that integrates theory with real-world applications. In doing so, graduates receive a well-rounded and technological background which helps them become highly productive professionals and industry leaders.

MSOE has a proven track record on their commitment to sustainability and being responsible stewards to the environment. The university has a dedicated website (http://www.msoe.edu/ about_msoe/green/) which exemplifies their achievements and initiatives taken. The latest acclaim to sustainability is for 2010, in which MSOE was named “one of the country’s most environmentally responsible colleges” according to Princeton Review.

New Paradigm Group recognizes MSOE as a proactive community leader in the promotion and investment of Figure 4.1: MSOE Campus Center Building sustainable efforts. The university is in the heart of downtown Milwaukee a prime real estate location, which has experienced an increasing number of renovations and new construction condominium projects. Putting teachings into practice would give MSOE a “greener existence” within the neighborhood and turn their prime location into energy-efficient property.

The average age of the buildings on campus is 55 years-old. Nine out of the fifteen buildings have been renovated into educational buildings, including the 1987 renovation of the Blatz Brewhouse into the Campus Center (Figure 4.1). With multiple aging buildings, MSOE is a prime candidate for energy efficient upgrades.

New Paradigm Group has assessed the university’s older building stock and has identified the 33 year-old Walter Figure 4.2: Blatz Brewhouse Schroeder Library as a prime retrofit candidate. The 52,000 square foot buildings consists of (3) floors with multiple rooms per floor. Upon the site visit and initial assessment of the existing conditions within the Library, New Paradigm Group immediately observed that minimal upgrades have been made to the electrical, mechanical, and plumbing systems. MSOE understands the benefits from more efficient and updated equipment and systems. Therefore, New Paradigm Group has been contracted to perform a comprehensive energy audit, followed by implementation of load-reduction measures with intentions and renewable-energy system installations.

Energy Use Analysis

Based on the customer’s electric utility bill for the last year, compared to the size of the building (~50,000 SF), the consumption was higher than average. A typical commercial building consumes about (5.9) watts per square foot and the Library calculates out to (7.78) watts per square foot; about 25% more than a modern facility. This presents a great opportunity for New Paradigm Group to provide energy saving and efficiency measures, that will benefit both parties.

Lighting Retrofit: Existing Conditions The Milwaukee School of Engineering library building has (3) floors, with two of them being identical study floors and the third consisting of offices and classrooms. Each floor is lit primarily with fluorescent (3) lamp T8 lay-in fixtures. On the two study floors there is no switch to turn off any of the fixtures, this means that they are on from open to close everyday of the week. This adds up to over (90) hours a week!

The lighting controls throughout the library building vary. The classrooms consists of an occupancy sensor in series with a toggle switch. The offices have dual level switching and the library has a lighting contactor with the relays powering banks of toggle switches. Note the South wall consists of a continuous curtain of windows, letting in a large amount of natural light, while all of the lay in fixtures are all on!

Figure 14.2: Library 2nd Floor South side looking West

Lighting Retrofit: Reflected Ceiling Plan We at New Paradigm Group recommend a one-for-one replacement of all the three lamp fluorescent T8 fixtures. Also, one lamp T8 cove fixtures will have an LED T8 lamps installed, downlights and track fixtures will have compact LED lamps replacing the existing incandescent and compact fluorescent lamps. The following floor plans show the reflected ceiling plan of the study floors and the classroom/ office floor.

Figure 15.1: MSOE Library 2nd Floor Lighting Plan

Figure 15.2: MSOE Library 3rd Floor Lighting Plan

15

Lighting Retrofit: Light Level Calculations Utilizing AGI32 to calculate the foot-candle light levels with the retrofit kits, and the available daylight, we can show the MSOE Library will meet the recommended light level of (35) to (50) foot-candles (Table 16.1), and also the 3rd floor Table 16.1: IES Recommended Lighting Functional Area Light Level Engineering Society (IES) develops standards, Classrooms - standard 50 FC design guides, and guidelines and calculation Offices - private 35 FC guides that improve the lighted environment Library - stacks 35 FC and benefit the public. The IES publishes a Library - reading area 50 FC lighting handbook that is a recognized offices and classrooms. The Illuminating

Results The AGI32 calculations for our retrofit shows that we will meet the recommended levels with an average of 41.8 foot candles (FC) on average.

Figure 16.1: AGI32 Calculated Lighting Levels with Lights ON (No sunlight)

The AGI32 calculations with light lights off and full daylight (Figure 16.2) indicate that natural light levels around the first two rows of lights from the windows will exceed the (90) FC level our daylight sensor will be set at. This confirms that the daylight sensors will provide the estimated energy savings when the sun is out.

Figure 16.2: AGI32 Calculated Lighting Levels from sunlight only (Light Fixtures are OFF).

16

Lighting Retrofit Design: Assessment New Paradigm Group assessed the existing lighting installed throughout the MSOE Library, and immediately came to two conclusions: 

The existing 3-lamp parabolic fixtures (Figure 17.1) provide more light than needed



Modern fixtures will deliver the required light more efficiently

Fig. 17.1: Typical Existing Fixture

We initially considered replacing the existing parabolic fixtures with LED fixtures or T8 retrofit kits (Figure 17.2). The cost of the retrofit kits are about (1/3) the cost of the LED replacements, factoring the lower power consumption of the LED fixtures is (12) watts less. The lamps we chose are the Sylvania FO32/XPSS/ Fig. 17.2: Lithonia ES8R Kit ECO3 that consume (28) watts each with an average life of 24,000 hours. This is (1/2) the life of the LED fixtures, but lamp replacements run about $12.50 each, including labor. Comparing both options, the LED is 15% more costly. We anticipate LED fixtures will continue to decrease in cost, becoming the better option for future retrofit projects.

Next, there is a continuous row of (1) lamp T8 cove lights (Figure 17.3) that illuminate the central corridor of the first and second floors. Here a LED lamp for lamp swap will provide a more cost effective option. The retrofit kit and the single LED lamp are virtually the same cost, but the lower power consumption of the LED 4’ T8 lamp (Figure 17.4) is (18) watts, compared to the (28) watts of the Sylvania lamp.

The Library has some track fixtures with MR16 lamps. We will replace these lamps with more efficient MR16 LED lamps that last (10) times longer and use 80% less energy.

The lobby areas of all three floors have compact fluorescent lamps that do not illuminate these areas effectively. New Paradigm Group highly suggests these (23) watt CFLs should be replaced with (15) watt PAR30 flood lamps that will do a better job lighting these lobby areas. In this instance, we will not only provide a 35% reduction in energy consumption, but improve the lighting dynamics of these areas.

Overall, the lighting retrofits will initially cost $50,648.00, and $47,876.00 after incentives. With an annual energy savings of $22,356, the payback is in just (2.14) years!

Lighting Retrofit: Light Fixture Recommendations The figures below show renderings, created in AGI-32, of the new light fixtures in the study area of the library. Figure 20.1 shows the lighting effect with the light fixtures on, where Figure 20.2 shows the effect of just daylight with the light fixtures off.

Figure 18.1: MSOE Library rendering with the Lights on

Figure 18.2: MSOE Library with just daylight; Lights are off

18

Lighting Controls Design: Assessment Upon the initial visit of the MSOE Library, on a bright February morning, it was difficult to ignore the abundance of natural light streaming through the continuous windows that run the length of the South wall (Figure 18.1). Our next observation was that all of the light fixtures were on, and there were are no occupancy sensors or daylight sensors installed throughout the library study area. This was the same for both the first and second floors.

We propose adding daylight sensors with dual level switch capability (Figure 18.2) . This way, the row of lights closest to the windows will turn off when a level of at least (60) FC is reached, the second row of lights will turn off at (90) FC . With a total of (86) fixtures, consuming (56) watts each, and an average of (4.5) hours of sunlight per day, a savings of $1,977 per year will be achieved.

Next, we will install dual technology occupancy sensors to control the library lights by (1/4) zones of the entire space. During the first and last hours of operation, much of the library is unoccupied, therefore why illuminate the entire facility? Utilizing the infrared and microphonic technology of the nLight nCM-PDT-10-2P, the false “on’s” are eliminated, increasing the system’s efficiency functionality.

The best characteristics of the nLight system is the ease of installation. All the devices are connected by a Category5 cable, which does not require a raceway if plenum rated, reducing installation costs. Up to 400 devices are connected to a nLight Gateway (Figure 18.3) that allows for on screen or a laptop connection to simply program the system in just minutes. All the nLight components are cost competitive with other devices, making this system the better choice.

Figure 19.1: MSOE Library South Wall

Figure 19.2: nLight duallevel Daylight Sensor

The nLight system can provide an energy savings of 40% or more, according to their literature. With an initial cost of $7,920.00, a final cost of $7,545.00 after incentives, and a calculated power consumption of 67,240 kWh per year for the lights under control, a payback can be realized in as little as 1.12 years! This is another “must do” project for MSOE to consider.

Figure 19.3: nLight Gateway

19

Lighting Controls: Installation Plan We at New Paradigm Group recommend the installation of dual-level daylight sensors to control the first two rows of fixtures closest to the windows. Occupancy sensors will control the open Library fixtures by the zones indicated in Figure 19.1 on both the first and second floors. Figure 19.2 shows where occupancy sensors will control the corridor lights on the 3rd floor. All the individual classrooms and offices already have occupancy sensors.

Figure 20.1: Daylight and Occupancy Sensor Layouts for the 1st and 2nd Floors

Figure 20.2: Occupancy Sensor Layout for the 3rd Floor Hallway

HVAC/Environmental Design: Assessment Current System: The Library currently uses the original 150 ton electric chiller/heat pump (Figure 21.1) with six 40kW electric heating elements to supply the heating and cooling needs of the building. The buildings total annual electricity load is 3,408,000 kWh, at $0.25/kWh this is an annual electricity cost of $852,000. Figuring the demand is 0.35 of the chiller/heatpump’s 400 amp 480 volt feeder, and of the (6) 40 kW heating elements, the calculated annual load is 1,755,419 kWh/year or 51% of the utility bill. The cost for this power at $0.25 kWh is $438,854.75 per year!

Figure 21.1: Existing MSOE Library Chiller

Proposed Energy Solution: Because of the age of the building there have been many advances in technology and we have decided to keep the existing system but offset the cost by installing an efficient Power Therm System: Hydrofire System (Figure 21.2). Power Therm Systems reduce fuel usage and energy costs, capture and utilize wasted thermal energy, and reduce the CO2 and greenhouse gases.

The Hydrofire System (Figure 21.3) uses a MicroTurbine to directly exhaust into the boiler to heat the water . The MicroTurbine Heat Recovery Module is used to product hot water from the Microturbine exhaust. This hot water can be used for domestic use, building heating, or processing heating requirements. The Turbine System will include the following:         

Capstone C65 Microturbine Heat recovery module Demand meter One 89L Gang operated disconnect One gas compressor Yazaki 20 ton water fired absorption chiller Serial to Ethernet controller for turbine Software Freight

21

Figure 21.2: Power Therm Hydrofire

Figure 21.3 :The Power Therm System

HVAC/Environmental Design: Assessment The annual power produced by this 65 Kw system would be 483,000 kWh and the maximum displaced heat from the cogen would be 24,000 Therms. This gives us an annual energy savings of $88,516. including the cost of the cogen fuel used by the Hydrochill System.

Monthly Savings Analysis: The Hydro Chill system solution provides 12.9% of the electricity plus 48% of the heat currently used by the facility, which accounts for another 18.2% of the current annual electricity consumed. The monthly net savings are $6,321.22 including maintenance.

Return on Investment: The cost for the Power Therm System to be put into the library was bid at $500,000 from Wesco Advanced Energy Solutions. With a $500,000 net lease amount , we could get a return in 7.33 years with inflation, and with an uninflated simple return 6.51 years. These returns assume annual rates of 3.00% for electricity, 3.00% for gas, and 13.00% for #6 heating oil.

Variable Frequency Drives Another recommendation is to install variable frequency drives (VFDs ) t0 the hot water and chilled water pumps. VFDs work by allowing the motor to run at an appropriate speed according to the load being placed on the motor. A motor without a VFD runs at full speed and higher amperage no matter how small the load is.

Adding these VFDs would be beneficial because they would help reduce the pumps’ electricity consumption, thus lowering the energy usage in the library. A payback in less than 9 months is anticipated from installing these VFDs.

22

Figure 22.1: Existing original starters for the hot water pumps

Photovoltaic System Design: Assessment Solar radiation has the highest power density compared to other renewable energy sources and provides maximum power during peak demand hours. This makes it a more ideal source of renewable energy source compared to wind energy. Several other benefits of harnessing the sunlight using a PV system, include the following 

Lower energy consumption



Savings on the electric utility bill



A reduction in the amount of green house gases emitted into the atmosphere

Another factor that will contribute to the performance of the modules is the operating temperature and location of the array itself. Being located in Milwaukee, where the average temperature is about 50°, photovoltaics arrays perform very efficiently. This is because high temperatures decrease the performance and efficiency of photovoltaic arrays.

Therefore, being located in a cooler climate, the arrays have a higher electrical output because the components are kept cool. A final advantage to being located in Milwaukee is that on clear days when there is snow on the ground, the arrays can have up to a 60% output increase from the light reflected off of the snow.

Figure 23.1: Example of a structurally mounted solar PV array; 20kW DC.

23

Photovoltaic System Design: Location Assessment The roof of MSOE’s library is an ideal location for photovoltaics due to an unobstructed southern exposure. Approximately 14,000 SF of roof space is available for photovoltaic arrays.

Benefits of a photovoltaic installation include: 

The arrays would not be blocked from the sun during the majority of the day



There are no tall nearby buildings or structures nearby to cast shadows



The long side of the roof faces south, allowing the arrays to face south and receive the maximum amount of direct

Figure 24.1: MSOE Library Satellite View (Google Maps)

sunlight New Paradigm Group plans to install a 30 kW array on the roof of the library, which will help to offset the electrical loads within the library. The arrays will be tilted at 35° to optimize the amount of solar radiation collected by the arrays. The weight and area of the solar modules is 54 lbs. and 18 sq. ft., respectively. This corresponds to a load of 3 psf for the photovoltaic array.

However, the project team is concerned whether or not the roof can handle the additional weight of the photovoltaic arrays. To ensure that the roof can handle the additional load, the capacity of the roof was calculated using structural drawings of the library. The roof of the library is a concrete slab with reinforcing steel. After calculating the capacity of the roof, it was determined that the additional load would not cause any cause any problems with the libraries roof.

24

Photovoltaic System Design: Schematic Design The one-line in Figure 25.1 depicts the proposed fixed/tilted array. The 30 kW utility-interactive system will operate in parallel with a nearby panel in the library. The solar modules of the 30 kW array will collect the sunlight and convert the solar radiation into DC current. The inverter will then convert the DC current into AC current that can be used to help supplement existing 120/208V single phase loads in the library.

INSERT FIGURE

Figure 25.1: Solar PV One-line Diagram

The array will be supported using a structural direct mount system. This system has several advantages: 

The feet of the solar array connects directly to the underlying structure of the roof.



If the roof needs to be replaced or repaired, the pv system does not have to be disturbed.



The arrays sit several feet off the ground, which allows the snow to slide off of the arrays and not collect on top of the array.

25

Photovoltaic System Design: Material Estimate As seen in Table 26.1, the solar modules and all of the components that will be needed will cost $111,464.00. The 30 kW array will be composed of 120 solar modules, three 10,000 W inverters, a racking system, flashing to surround the feet of the array, pipe, wire, and miscellaneous hardware.

There will be no shipping cost for the solar modules themselves because they can be picked up directly from the supplier, which is located in downtown Milwaukee.

It is estimated that it will take (569) man hours to install the photovoltaic arrays. This amounts to $39,506 after overhead and markup is added in. After taking into account a 30% depreciation and adding markup to the materials, it is estimated that the it will cost $111,530 to install the arrays.

Using a PV watts, it is estimated that the 30 kW array will generate $9,644 of energy per year.

This amounts to a payback of 11.56 years. More detailed information about the schematic estimate and payback can be found in the Appendix.

Utilizing Wind Energy Why Wind?

Wind is a natural resource that can be harvested and used to generate power. Wind power can save money and energy. By using a renewable source of power such as wind, a company can help offset rising utility costs and they can reduce their dependence on the grid.

There is another huge benefit for investing in a wind turbine. There is a major shift in today’s society thinking about being more environmentally conscience. Installing a wind turbine in front of the building will draw attention from the public, it will let them know that MSOE cares about doing their part to help Figure 27.1: Renewegy Facility the environment. It will also be a learning tool for the students on campus. The wind turbine will be an interactive educational opportunity that will teach students about renewable energy. It will be especially beneficial to the architectural engineering students who will be dealing with them in the future. The mechanical and electrical engineering students will also benefit from the opportunity to study all the internal components of the turbine.

Utilizing Wind Energy

The major obstacle to deal with when installing a wind turbine is the extremely high initial cost. It is an extremely big investment that needs to be considered carefully. Another obstacle that needs to be considered is the location of the library. It is located near several residential buildings. The noise and vibrations generated from a wind turbine would not be appreciated by surrounding residents.

When researching different wind turbines we decided that Renewegy offered the best choice. They are located in Oshkosh Wisconsin, which is about 90 miles away from Milwaukee. This will cut down on some of the transportation cost. It will also allow MSOE to invest in a local company.

Renewegy offers a smaller wind Figure 28.1: Renewegy 30 Meter Tower Delivery turbine that is only 100’ tall and has a diameter around 32’. A huge benefit to installing this smaller wind turbine is its ability to be maintained. The wind turbine is designed with the ability to be tilted down to the ground which allows for easier maintenance. This particular wind turbine is rated for 20kW, and runs at wind speeds of 3.5-25 mph. This is a much better range than the standard wind turbine which starting wind speed required is 7.5mph. When researching the feasibility of using a wind turbine, the local annual average wind speed was found to be 12.5mph., which is about the middle of the turbine’s range.

The payback for this particular wind turbine is about 14 years. The team researched the output of a wind turbine that was located near our site, and averaged its output over three months. We applied those numbers to our turbine and came out with an output of 26,100kwh/year. This is about 0.9% of the current power usage of the library.

Schematic Estimate After an extensive evaluation, New Paradigm Group had determined that all of the proposed energy efficiency upgrades are feasible for the MSOE Library. We are excited to present our client with effective and efficient projects that will reduce their reliance on the local utility, and provide several educational examples for the esteemed school of engineering.

Our cost estimate includes:     

A complete interior lighting retrofit upgrade Intelligent Lighting Control system, featuring daylight and occupancy sensors A 30,000 kW photovoltaic solar array A 20,000 kW Wind Generator A Power Therm System to offset the building environmental cooling, heating, and power from the local utility

All the total costs include materials, labor, supervision, equipment, waste and recycling, permits, fees, overhead, and profit. Material and equipment costs were provided by competitive quotes from vendors, such as:  WESCO Electric Supply (Solar and Power Therm System)  Viking Electric Supply (Lighting and Lighting Controls)  Werner Electric Supply (Renewegy Wind Generator) All the Work for the projects will take place during normal hours, Monday through Friday.

Labor rates and overhead are based on the current rates of the Milwaukee Area NECA Contractors, utilizing modified units of labor from PC based software.

Chart 29.1 represents the overall cost breakout, indicating that Materials make up the majority. Since Materials are a relatively fixed cost, and Labor is the greatest variable, the overall risk for this project is lower than most, making this a much more attractive project to pursue.

Schematic Schedule New Paradigm took into consideration MSOE’s school schedule to minimize interference, therefore we have scheduled the construction to begin and end in the summer months.

The schedule is broken into four main components, Lighting Retrofits and Controls, Power Therm System, Solar Photovoltaic Array, and Wind Turbine. Our schedule accounts for a typical 40 hour week with Saturday and Sunday being non working days as well as Memorial day and Independence Day. We will begin construction on May 29th and end with substantial completion on August 24th.

Below is a Gantt chart specifying start and end dates for individual activities.

Financing Plan: Grants, Rebates, and Incentives

New Paradigm Group set out to identify any and all applicable grants, rebates, and incentives that our client would qualify for. Focus on Energy offers various incentives for efficient lighting and controls upgrades (Table 32.1). These savings are included in the detailed estimates found in the Appendix of this proposal.

Unfortunately, there are very limited options for a non-profit, tax exempt entity, such as MSOE, for renewable energy projects. All utility non-profit grants ended as of July 1st, 2011, and there are only Focus on Energy incentives available for residential customers.

Because of MSOE’s Federal tax exemption, they do not qualify for the 30% Federal tax credit. The State of Wisconsin does allow for a sales tax exemption on all renewable energy product purchases, but MSOE is a tax-exempt entity, so this does not apply.

There are Focus on Energy rebates for the installation of Variable Frequency Drives (VFDs) that we propose for the existing hot and chilled water pumps. But for the Power Therm system, because it is a supplemental system, does not qualify for any incentives or rebates.

32

Financing Plan: Loan Programs

The City of Milwaukee has a great program that is available to businesses, such as MSOE, for the financing of energy efficiency project. The program is called Me2,, which stands for “Milwaukee Energy Efficiency”. Me2 offers four options: 

Smart Security Financing that provides up-front collateral for projects from $10,000 to $1,000,000.



Small Business Financing that allows you to finance up to 100% of the project at a low rate, but the loan must be between $5,000 and $20,000.



Clean Energy Financing allows (residential) property owners to finance energy efficiency projects from $20,000 through $5,000,000, as long as the owner passes on the savings to the tenant.



Interest Rate Buy Down is for projects between $10,000 and $500,000, and allows for a discount, or buy down, on your project loan.

The main qualification is that the monthly payment on the loan must be less than the energy savings per month.

New Paradigm Group will apply the Interest Rate Buy Down to the entire project, with two separate loans; one for the Power Therm system and one for the Lighting and Renewable projects. Current commercial rates are about 6.0%, therefore we will use a 3.0% rate for our purposes.

New Paradigm Group has determined that all of the proposed projects, with financing through Me2, are feasible with the determined parameters. Utilizing the Smart Security Financing and Interest Rate Buy Down options, there will be NO initial cost incurred by the client (MSOE), and the monthly savings will more than cover the monthly payments.

After each loan is satisfied, MSOE will receive the full monthly savings for the remainder of the system lifetime.

LEED for Existing Buildings LEED for existing buildings is a rating standard used by retrofit buildings to determine the design, construction and operation of high performance green buildings. This rating system is developed by the US. Green Building Council. LEED 2009 is the standard that is currently in use and identifies and rewards current best practices and provides an outline for the building to use less energy, water, and natural resources as well as improve the overall indoor environment and uncover operating inefficiencies the building may have.

Figure 34.1: LEED Points Earned

According to the LEED 2009 for Existing Building: Operations & Maintenance project checklist we will meet the LEED certification standard which is a LEED rating above (40) points.

The elements of our retrofit design that has helped us achieve this LEED certification include the following design elements that were detailed earlier in this proposal.     

Retrofit kits for the fixtures converting (3) lamp fixtures to (2) lamp T-8 fixtures.

Lighting controls utilizing daylight sensors and occupancy sensors.

Installation of a Power Therm System to offset heating and cooling costs.

Implementation of a 30 kW solar photovoltaic systems on the roof.

Building a 20 kW wind turbine adjacent to the library.

With these retrofits we have been able to achieve a LEED certified building with a total of 46 points while there are many more retrofits that could be done to increase the LEED rating we believe the costs and payback to not be worth it in our opinion and for now currently suggest only the following retrofits described in the previous sections of the proposal.

Shown on the following pages is the LEED breakdown that will give you a detailed look on what points we were able to achieve.

Outreach Appendix: Campus Energy Awareness

Existing Programs Energy awareness is high at MSOE, with many sustainable examples around campus.

Our main campus center building has a 30kw solar array on it that provides interactive displays that students can see the amount of energy being saved by the system.

With the help of ideas from last years green energy challenge proposal the lighting has been upgraded to T8 fixtures in the RWJ dorm building on campus. Additionally a solar reheat system was installed on the roof of the MLH dorm building across the street.

MSOE has a single-stream recycling program, composting program and paper recycling program. A single-stream recycling program allows MSOE to collect plastic, glass, aluminum, clean cardboard and newsprint.

Mixed recycling increases participation and recovery. MSOE has partnered with Growing Power for composting our new biodegradable dining products. Additionally MSOE established a dedicated paper recycling and shredding stream.

A drink refill program on campus allows students to buy water bottles at a 20% discount and fill them up at 50% off the original drink price.

Student Awareness To assist in the proposal and get students involved in the Green Energy Challenge Professor Dudley Outcalt, PhD., integrated our topics with his junior level classes. For Advanced Lighting/Communications Dr. Outcalt taught AGi32 and we used the photometric calculations in our proposal.

For Advanced Power Design Dr. Outcalt taught Power distribution with focus on PTW-32, coordination, arc flash studies and labels.

Also to get other students throughout campus involved we took a survey of 40 students that were working at the library. The survey asked about their opinions of light levels, energy usage and lighting controls. The response was favorable to the ideas we proposed. As we expected many students thought that the light levels were high and lighting controls would ideal. The survey and results are located on the next page.

Outreach Appendix: Campus Energy Awareness New Plan We plan to increase the energy awareness around the school by showcasing the new technology that would be installed for the library retrofit. While we already have interactive displays showcasing the energy savings of the Campus Center building we would add to that by showcasing the new energy savings of the photovoltaic system on the roof of the library as well as the proposed wind turbine to be installed near the library. We purpose a green energy platform for MSOE that would provide website access as well as displays around Figure 39.1: Home Screen of Solar Array Display campus that would rotate through all the energy saving ideas implemented on campus. So to put our plan into action we went to Armund Janto with our idea and he agreed to let us put up a display in the Campus Center to test out the idea.

Feedback seemed positive and we think this will draw more people to MSOE and it keeps everyone involved in energy awareness. The figures on the right are pictures of what was put in the Campus Figure 39.2: System Status of Solar Array Center and what we would like to propose to be located around campus. The display incorporates a mouse that lets you select different pages that display information on energy savings and even a live webcam of the solar array/wind turbine.

We also would like to purpose increasing energy awareness throughout all engineering disciplines around campus. Historically engineering and construction management disciplines have been centered on initial cost with lower cost being king. We want to implement the knowledge that most energy efficient ideas come with a larger initial cost but with lower lifetime costs which is important to an owner and community. Green energy can be implemented not only in architectural engineering and construction management department but also in other engineering disciplines offered at MSOE as all engineering uses some type of power to operate or produce.

Outreach Appendix: Article in University Newsletter

Green Energy Challenge Published: 02/09/2012 Members of MSOE’s National Electrical Contractors Association (NECA) student chapter are preparing for the Green Energy Challenge, which is the 4th Annual NECA/EI (ELECTRI International) Student Chapter Competition. They are one of eighteen NECA Student Chapters across the country that are participating in the 2012 challenge. This year, teams will select a facility on their campus, conduct an energy audit of the building's power and lighting systems, and design and propose a retrofit for both systems. MSOE's team is focusing on the Walter Schroeder Library.

The team is hoping to continue their winning streak this year, as they’ve won the championship the past two years. Assistant Professor Dr. Dudley Outcalt is the faculty advisor for MSOE’s NECA student chapter, and members Nicholas Cote, Christopher Kneeland, Courtney Leaf, Brittany Leis, Tanya Otto, Elise Pinkerton, Dylan Sandretto and Derek Underdahl will be representing MSOE. As in the past, the team is working with Local NECA Milwaukee Chapter for assistance on this year’s proposal.

ELECTRI International's jury — contractors and industry partners — will judge each written entry and select three finalist teams to bring to the NECA 2012 Convention in Las Vegas for oral presentations. They are also encouraged to use NECAWORKS™ - a web-based energy and economic screening tool — which will be made available to all students participating in the 2012 Green Energy Challenge.

Outreach Appendix: Arc Flash Study Safety is always a high priority for New Paradigm Group. We regularly evaluated arc flash conditions on our client’s equipment along with a short circuit study, and a coordination study.

Our team also evaluated the existing equipment.

After the arc flash evaluation, we found some conditions to be unsafe. The secondary side of the transformer connected to a receptacle panel was classified as dangerous (category 2) and required arc-rated clothing and protective gear. Arc flash labels, like the one shown below were made and installed in locations that were indicated as dangerous from the arc flash evaluation.

After conducting the short circuit study, we found the system to be properly protected if any faults were to occur. The coordination study proved the equipment used was well integrated to prevent any potential hazardous situations.

Due to an originally well-designed power distribution system, no measures were needed in regards to short circuit protection or equipment coordination.
