Project Summary

Executive Summary

The National Electrical Contracting Association (NECA) sponsored Green Energy Challenge for the 2014 year involves the re‐innovation of lighting and power systems of a student union center for increased energy efficiency and energy awareness. At the Rochester Institute of Technology, the Student Alumni Union is a building that would be much improved from the major implementations to be proposed.

RIT's original campus was located in downtown Rochester however as the school grew in enrollment, RIT's Board of Trustees felt that the Institute should expand and relocate. On November 21, 1961, the Board voted to build a new campus in Henrietta. That same night, as soon as student leaders heard the exciting news, the Student Association (predecessor to Student Government) voted to donate $10,000 towards construction of the new campus. This donation was set toward the foundation of the current student union. Based on the intentions of the Board to want the name of the new “Union” to both reflect a sense of hospitality to the RIT community and the represent the strong relationship between the RIT population and its alumni, they named it the "College Alumni Union." Students recently lobbied to change the name so that it may better represent the fact that students need a place dedicated for students. The Student Alumni Union was then adopted. Today the SAU is a living and learning 2‐story laboratory, whose services and programs promote student interaction, experiential education, and self‐governance in partnership with RIT faculty and staff.

A preliminary analysis of the SAU mainly found concerns on the energy consumption uses. The main issue discovered was that despite the relatively large use of glass to allow in natural lighting, a lot of light fixtures were still in use during the daytime. This provided an excellent opportunity to determine the power losses in utilizing those lighting fixtures during the bright daylight. Other concerns included the source of heat loss from the glass panels that would raise the need for additional heating during colder months and the fact that the high ceilings create excess heating supply when not needed.

Our proposal aims to improve the energy efficiency of RIT’s Student Alumni Union building by converting all lighting to higher efficiency bulb and lighting arrays, utilizing more motion activated and timer sensitive lighting sensors, installing arrays of PV panels on the roof and several small wind turbines along the SAU portion of the Quarter Mile to supplement the electrical energy consumption, introducing a sub‐metering, monitoring and feedback systems for maintaining and observing efficiency and for recreational self‐education to the students and RIT’s public, adapting necessary windows to reduce heat losses in the winter and cooling costs in the summer, and considering a revised HVAC system to provide better temperature distribution.

RIT would like to utilize the weight factor adjustment and apply a 1.4 multiplier to the sub‐metering and monitoring section and a 0.6 factor on the solar/alternative energy section.

Mission Statement The central objective of this proposal is to develop an economical and systematic approach to reducing the energy consumption of the RIT Student Union building encompassing areas of renewable energy, efficient and effective lighting and adequate temperature control.

Summary of Client

RIT, formally known as the Rochester Institute of Technology, was founded in 1829 as the Rochester Athenaeum, an association to promote science, literature, and fine arts. In 1847 the Athenaeum merges with the Mechanics Literary Association to become the Rochester Athenaeum and Mechanics Association. By 1891, the Rochester Athenaeum and Mechanics Association merged with the popular Mechanics Institute founded by Captain Henry Lomb and mainly others to further the educational outreach to all people of learning. The result was a success with an ever increasing student body and faculty, the Rochester Athenaeum and Mechanics Institute was forced to relocate out of the limited Rochester city borders. The school was renamed the Rochester Institute of Technology to invoke the focus of the institute to develop young minds to the innovating realms of science and technology.

Today, RIT holds 1,300 acres of Suburban Rochester and is home to several different colleges and majors. The outstanding degrees and opportunities have brought forth over 15,000 undergraduate and 2,900 graduate students. Enrolled students represent all 50 states and more than 100 countries worldwide. RIT is also a renowned international leader in preparing deaf and hard‐of‐hearing students for successful careers in professional and technical fields. The university provides access and support services for the more than 1,200 deaf and hard‐of‐hearing students who live, study, and work with hearing students on the RIT campus. This student diversity is a testament to the focus on learning and innovation standards held by the institute. For this reason the college takes great pride in student work and projects presenting several opportunities for learning and research. Another reason for RIT’s success is its focus on a strong co‐op program that allows students to gain working experience during their college degree. Students successful on co‐op internships are often found to more easily find full employment after graduation.

In more recent years, RIT has shifted its focus to sustainability. The Golisano Institute for Sustainability, completed in 2013, has provide the institute with several honors and great recognition as a promoter of energy efficiency with all types of alternate energy sources. The Sustainability Institute Hall is an 84,000‐square‐foot state‐of‐the‐art laboratory for scientific discovery and experiential learning. The building welcomed several new master’s degree and Ph.D. programs in sustainability and architecture. Specifically designed and constructed to meet Leadership in Energy and Environmental Design (LEED) standards of the U.S. Green Building Council, RIT now holds three LEED awards with one LEED Platinum (University Services Center) and one LEED Gold (Engineering Technology Hall) facility. However, the GIS building is the largest and most advanced project to date.

Following in the pride of RIT’s sustainability efforts, this year’s NECA challenge of retrofitting the Student Union building to be more energy efficient provides a goal that is perfectly in line perfectly with the current ideals of the Institute. However, unlike the Sustainability building that was created from the bottom to be highly energy efficient, the task with the current student union presents a different challenge. The Student Alumni Union can be said to be located close to the heart of the RIT campus. Found on the long stretch of walkway known as the Quarter‐Mile, the SAU bridges the gap between the academic side of campus and the residential estates and dorms. The SAU is home to several areas of interest to many students of the RIT community. The following list is a breakup of the various areas found at RIT’s SAU by floor level.

Basement: RITz Sports Zone dining venue, the underground tunnels, Tech Crew and various other student organization rooms First Floor: Brick City Cafeteria, Fireside lounge, Ingle Auditorium, the SAU common area which includes Ben & Jerry’s and Nathan’s eateries, the writing center, the Photo center, Beans, Artisanos, and other miscellaneous areas Second floor: MCAS, Conference rooms and the homework center

The fireside lounge provides a great and accessible area for students often used for social

events that encourage students to talk, share ideas, or simply hang out. Moving past the fireside lounge leads to the Ingle Auditorium, a large theater that also serves as a social event for students to enjoy movies and presentations of all kinds. The Brick City cafeteria, Ben & Jerry's, and Nathan’s Soup and Salad are all locations found through the SAU common area. The Common area is a large open room with vaulted glass ceilings that typically serves as a fundraising and outreach area for several of RIT’s clubs and associations. There are other areas of interest found in the SAU including the RITz Sports Zone in the basement and the Multicultural Center for Academic Success (MCAS) on the second floor.

The SAU also acts as a pathway connected to the Campus Center in which several of RIT clubs host meetings such as the Organization for African Students (OAS), Asian Culture Society (ACS) as well as institute centers like the Women in Technology center. It is also connected to the interfaith student chapel in which several campus religions are able to host services and events throughout the school year. Many students utilize the pathway of the SAU to avoid the narrow wind tunnels between buildings especially during the cold winters.

Page | 5


With all these locations to consider there are as many areas to improve the SAU as a whole as well as challenges to overcome. For this proposal, the focus of the redesign will be limited to the lighting, heating, and feed monitoring technologies that could be installed to radically improve the energy use of the building. Solar and wind power will also provide an excellent source of renewable energy that could reduce the energy load significantly depending on the seasons. The close proximity of some RIT buildings to the SAU provide excellent wind tunnels that could be taken advantage of with wind turbines during the fall and winter months. The spring and summer months bring out a strong sunlight that could be effectively absorbed by solar cells placed on empty rooftop of the SAU as stored energy or used to power the building entirely during the low power consumption vacation.

Energy Use Audit & Analysis

Given the RIT Student Alumni Union’s current state, it was expected that the current cost of energy usage to be rather high. Through an investigation of the building, it was found the most of the lighting fixtures currently utilize T‐8 and twin tube T‐4 fluorescent bulbs. Each T‐8 bulb has an 18W rating while the T‐4 fluorescent bulbs have a 38W rating. And although these power ratings may not be that high, there are still effective ways to reduce the power load. The fact that most of the lights in the building seemed to be left on, 24/7, presents further concern to the energy in‐efficiency rating of the SAU. Even an 18W rating bulb kept on for 12 months would certainly generate a shocking lighting bill from the local power provider.

From a preliminary standpoint, this proposal aims to replace the existing T‐8 and twin tube T‐4 fluorescent lighting fixtures with Light Emitting Diodes (LED) fixtures for increased energy efficiency. The replacement will allow for much better visual lighting as well as low cost energy consumption. Some existing lighting fixtures that have already been transitioned over to LED bulbs and the lighting contrast can be easily identified between the LED bulbs and the various other bulbs in the building.

For the heating and cooling system employed in the SAU, the ventilation systems are located high up on the walls close to the ceiling. This prevents a bit of an issue especially since several areas in the building have over 20 foot high ceilings and large open spaces. This means that the heat that is pumped into the buildings open areas from the roof get trapped on top of the higher density cold air closer to the ground. By the time the air is able to mix within itself to bring the warm are to the floor level then a large amount of energy has consumed with much of the needed warm air still high at the ceiling.

There are some ways to improve this heating problem that will be discussed later. The aim of these implementations would be to possibly replace the current Heating Ventilation Air Conditioning system (HVAC) that would allow for fast heating and cooling of the main open areas of the SAU while still maintaining a low as possible power rating.

It was also discussed that the energy systems can further provide benefit with the addition of digital lighting management controllers. It is not just about the change to more efficient, less power rating lightings, we also aim to allow easy access of vital information of the lighting controls to the facility managers. They can better assess which areas of the SAU are utilized the most and devise ways to provide power to those areas while reducing the consumption of the less traveled hallways. See the “Sub‐Metering and Monitoring” section for more information.

Based on a $0.25kW/h price estimate, it was found that about ¼ of the total energy was

used by the lighting system while the rest was most consumed by gas. This is attributed to the

various numbers of kitchen establishments and shops in the SAU that require the gas for food

preparation. The other large amount of gas consumption would be directed to heating.

Based on the current lighting and HVAC system used in the SAU, the power rating cost was compiled for the 2012‐2013 academic school year. The results of this is shown in the table above. The table shows the power usage beginning with July 2012 and ending in June of 2013. The total combined power usage for the Student Union was over 1 million kWh. It goes without saying that the technological proposals to be made in this document could go a long way to reduce the total power use of the building by a significant amount.

Before the systems to be retrofitted into the building are analyzed, there are several more conclusions that can be drawn from Table X. Focusing on the SAU power monthly consumption will help determine which systems are generating the most cost since the breakdown details were not directly provided. To do this a better visual representation of the time scale is required.

Graph 1

The graph above provides the perfect visual illustration to better detail the consumption during the given time period. To begin with, it can be seen that the SAU power use is at its lowest point during the summer months (June, July and August). This decline in power use represents no surprise since the majority of the student population is not in attendance during those months. Some students are off on vacation or co‐op while the faculty is also rarely on campus. Since there are very few events hosted during the summer time, the power rating would be suspect if it were not the lowest values.

Likewise the sharp increase in the SAU utility is expected in the Fall season months. Students and faculty alike return to the school and make the SAU a common area to relax or pass through on the way to the academic side. It is interesting to note that the highest consumption was found the fall semester. This could be due to the several early school year events hosted throughout the SAU to welcome new students to the Institute. The winter and

spring months also witness a greater use of utilities compared to the summer, but lower than that of the fall season consumption. This could be attributed to the long winter break between semesters in which many students return home for the holidays.

If the increase in power use from summer to fall is attributed to the use of the heating system to keep the building warm then the increase in the spring semester can be likewise linked to the use of the cooling system. Keeping in mind that the SAU has several glass panels and windows used to take in as much natural light as possible, it is only reasonable that the heating utility in the winter would be much greater that the cooling power needed in the spring.

Lighting Retrofit

A more detail analysis of the current lighting system revealed that RIT has already been taking steps to retrofit the energy efficiency of the SAU in small ways. For example some of the 32 watt 4 ft. T‐8 fluorescent lamps had been changed to 18 watt LED 4 ft. T‐8 in the fixtures in the A‐level hallway. These fixtures have two lamps each, which would greatly reduce the wiring cost. The ballasts on the light fixtures were also removed which reduced the energy use by 3 watts per fixture. These changes were made in the Fireside Lounge and most of the open areas in the SAU.

Several areas in the SAU were found to undergone recent renovations in which the lighting was updated. 150w Metal Halide lamps were installed in the Davis Room along with (two or three) big bowl fixtures .The Ritz Sports Zone and the Music Room, in the basement A‐level, also recently underwent renovations in which the lighting fixtures were changed. The RIT photo shop and the SAU lobby on the 1st floor had have also had some recent light changes. All the floor and lighting schematics for the various areas in the SAU can be found in the Appendix section of this document. The figure on the next page shows the proposed design for lighting systems changes, following several of the existing layouts, for the first floor of the SAU. The other two floors will follow this same design.

Page | 14


Although RIT has made recent renovations to the SAU and has widely accepted the adoption of LED lighting, there are still a few lighting areas that have yet to be adjusted. These mainly pertain to the large HID lamps used in the open spaces of the SAU to maximize lighting and the issue of the abundant natural lighting in the building. The main concern with the High Intensity Discharge (HID) bulbs is that the energy consumption for these bulbs is far too great despite the large light emission they produce. HID bulbs create light through the electron arc between two metal surfaces that vaporizes metal vapor within the bulb. It is proposed that these HID bulbs although successful in the purpose of generate high intensity beams in the open halls of the SAU, should be replaced by more energy efficient LED bulbs. The advantage of HID is that the energy beam can be directly focused on a specific area providing maximum lighting whereas LEDs generate equal light waves in all directions; however LEDs have been proven are much more durable, faster switching between states, and save on energy usage. There are also some Halogen flood lights in the building that could be replaced with LED flood lights for better visual lighting.

The other area of concern was with the amount of heat loss through the many glass panels

and windows found throughout the SAU. There exists a balance between having as much

natural lighting as possible to minimize the lighting load but also keeping the heat load to a

minimum to reduce power usage. This is not an easy fix however a simpler solution can be

derived for the natural lighting that would benefit both sides of the problem.

Figure A – SageGlass, Tint‐Adjustable Glass

Table C – SageGlass Tint Statistics

Replacing all the glass skylights with a product like SageGlass would cut Energy cost by 20% and HVAC cost by 10%. However at around $60 per square foot the cost to replace all existing skylights would not be economically feasible. A retrofit is the only answer with a laminate smart film at around $40 would be better. The film would adjust the amount of solar light through the skylights and can be wirelessly managed throughout the year to find a sweet spot that compliments the HVAC units.

Page | 16


The smart film works be creating a digital shutter based on the amount of light imposed on the surface. The technology effectively runs an electric current through the laminate and shifts the semi‐conductive glass cells or liquid crystal molecules. When no power signal is applied, the molecules are disordered and prevent light transparency however with an AC voltage signal the molecules are arranged more structurally allowing more light through. One analogy would be a shift from amorphous glass structure to a crystalline structure with the application of energy. This adjustment allows for natural light in take or blocks out the UV light and dims the material. Placing this material on the skylights and glass windows found through the SAU could provide a solution to the natural lighting and heating problem. The transparency range has been tested from 4% to 80% depending on the size of the glass.

The economical challenge with smart film materials over the years has been the laminate material that binds the glass to the conductive material. Although improvements in laminate or adhesive composite materials have certainly caused a reduction in cost it is still only marginally beneficial to implement this solution since the current cost are still too high for economical use. However this is certainly a promising system that could be employed in the future as the technology improves.

Alternative Energy Assessment

Solar Energy

The use of solar energy always provides a reliable source of energy to the Student Union. It was found that the SAU has ample roof space which will be used to incorporate photovoltaic panels for energy generation. The figure below shows highlighted regions for proposed PV panel locations. Using Google satellite view, the sky view of the building was captured in the Figure B. Based on the scale of the image, all distances could be closely. The various regions on the roof were selected based on the areas that provided the largest surface area free of any ventilation or heating system.

Page | 17


Figure B – Overview of SAU and PV Panel Locations

From the image, the shades impact from the buildings helped indicate that each array of panels will face south for maximum sun exposure. Given the placement of Rochester with respect to the equator, a given the school’s latitude of 43.08 degrees, a tilt of about 35 degrees from horizontal would provide the optimum energy availability.

From the areas selected, measurements could be estimated based on the scaling of the image used. The estimated areas for all the selected areas and the total area was calculated below. The sum of these individual spaces constructed the estimate of the total “free” area available to any analysis. Table D ‐ Available Roof Area

2 42 28 1176

3 60 54 3240

4 66 37 2442

Total ‐ ‐ 9083

This total available area for PV panels, approximated at about 9083 square feet, found presents a great opportunity to reduce the energy dependence of the SAU building on campus. Given the ever increasing advancements in current solar cell technology and manufacturing, the prices seem to decrease yearly. This would mean that the cost of purchasing and installation should not be a determinant factor in the choice to use it. For the retrofit of the SAU, photovoltaic cells will be considered.

Page | 18


Wind Energy

As stated earlier, the amount of brick building around the campus of RIT presents a unique situation where winds are forced to flow through the tight spacing between certain buildings. This always creates a strong wind tunnel that could also be utilized to reduce the energy load of the building. FIGURE C ‐ Proposed Wind Turbine Structure Placement

The perfect place for a wind turbine system was found between the SAU and George Eastman building found on the Quarter Mile. This narrow corridor always sees fit to supply a steady wind stream and during the fall and spring seasons, the energy generated from this wind tunnel could be quite significant.

Recently, RIT was able to install a set of wind turbines for the Golisano Sustainability building. Based off the vertical axis windmill technology already employed on campus, each turbine is capable of generating 1kW. If the turbines are positioned so the blades are parallel to the wind flow through the tunnel then a maximum of 2‐4 turbines depending on the length of the supporting beam.

The vertical axis turbine system was selected due to the ability of the

rotors to generate electricity by rotation about the vertical axis from the kinetic energy of the wind, and given the direction of typical air flow along the Quarter‐Mile. This provides a simple transfer of mechanical energy into electricity since the number of components in the system are minimized along with frictional losses. The combination of 2‐4 turbines with 1kW of power per turbine would result in a maximum power load decrease of 4kW.

Page | 19


Analyzing both the solar and wind together would provide a better understanding of both

systems and the benefits to the energy efficiency with the combination of the two. The values

given represent an average rating based on the estimated values from Kyocera Solar

Corporation and the SRM windmill Power Corporation. Table E is only used to provide an

For wind power, the fuel source (wind) must be carefully observed for the Rochester area to determine the exact times of the year in which power could be generated. The following graph represents the average wind speeds throughout the calendar year. Make note that this graph provides a modest estimation of wind levels on campus, given the unique layout of buildings, so actual power generation may be higher.

Sub‐Metering, Monitoring, and Feedback Systems

Several of the buildings around campus utilize a combination of two monitoring and control systems to regulate energy usage. RIT’s newest building, the Golisano Institute for Sustainability, combines WattStopper and Automated Logic systems throughout the building, and is to be used as a model for the energy retrofit of the SAU.

The WattStopper digital lighting management systems function as a chain of networked lighting controls. Each out‐of‐the‐box component can function independently or can be combined with others to form a control infrastructure. The intended controls to be used throughout classrooms, hallways, and common areas within the SAU include occupancy sensors and photo sensing daylighting controls, as well as digital control switches. Each sub‐system of the building‐‐determined by electrical layout, typically by room or space‐‐will also require the necessary network components for remote system management and intercommunication.

Some of the key characteristics of the WattStopper system to be incorporated into the SAU for better energy efficiency include 90 degree lighting control. This term signifies that while individual rows of lights may be controlled via switches or photo sensors, each column (if applicable) can be digitally controlled. This style of lateral lighting control can allow for significant energy savings when used, as fewer lights remain on. Figure D ‐ Typical WattStopper Digital Lighting Management System Layout

Occupancy sensors will provide increased benefits to smaller rooms and hallways throughout the three floors of the building. For many of the classrooms and office areas, a ‘vacancy versus occupancy’ premise will be implemented as a way to further reduced wasted energy from unnecessary light usage. This concept involves a ‘Vacancy On’, ‘Occupancy Off’ principle. Digital switches are used to manually turn on lights in the ‘Vacancy On’ scenario; essentially, lighting will not turn on until needed. Any instance where a student or faculty member runs into an area quickly to grab something (a situation which normally activates the sensors to turn on the lights for a period of at least 20 minutes) can be avoided. Occupancy sensors are then used to determine when lights are turned off, by person or persons occupying a given area and timed signals to sense this information. Lavatories will solely use occupancy sensors, for ease of individuals. The majority of the lavatories within the SAU currently make use of occupancy sensors.

The type of occupancy sensors intended to be used in the various low ceiling areas of the Student Alumni Union, such as the offices and hallways, are digital ultrasonic ceiling mount sensors. Pictured below on the left, the sensor relies on ultrasonic technology to send and receive signals for 360 degree coverage, based on the occupancy of an area. These sensors are easily configurable, through the IR transceiver, for higher or lower ultrasonic sensitivity to pick up the presence of quieter individuals. Additionally, the time delay and walk thru settings can be adjusted for maximum energy efficiency. These occupancy sensors plug and connect to the WattStopper Digital Lighting Management system, for automatic control over lighting use.

Average cost is about $225 per sensor before quantity discount. Currently NYSERDA is offering a $50 per sensor rebate.

For higher ceilings, such as those in the Davis room eating area or Fireside Lounge, occupancy sensors that utilize passive infrared will be used, as they function in applications of up to 40 feet. They will be incorporated into the digital lighting management system for the SAU with the other sensors and digital controls. See the above right picture for an example of the PIR style occupancy sensors.

Daylighting controls will be used throughout the SAU to monitor ambient light levels and capitalize on existing light, in order to minimize energy use while still providing ideal lighting conditions. The photo sensors offered by WattStopper will serve to measure daylight levels and communicate with the DLM to dim or brighten lighting fixtures accordingly.

The Automated Logic WebCTRL system is automated building interface, accessible through a variety of internet platforms. It allows for access to the BAS (or building automation systems) and provides trending, logical alarming, and monitoring and energy data storage features, in addition to its direct control over the buildings systems with the click of a mouse. Below are screenshots taken from the software configured for RIT’s Golisano Institute for Sustainability (GIS) building. The software is configured for each area of the building that requires lighting, broken down by floor level. The colored strips represent each light fixture and its current operating level, given momentary refresh rates.

This allows for detailed monitoring and feedback for each system within a building. As to be used in the SAU, it can pinpoint any areas that may be offline or equipment that has malfunctioned. Figure E – Automated Logic Software, Floor Plan

Page | 24


The trending feature tracks energy usage over the course of each day for any given sub‐section of the building’s electrical (or mechanical) systems. Figure E, below, shows trend graphs for one particular room in the GIS building. It lists average load time, or time for lights spent on, duration of room occupancy, and average light levels for the room. Configured and mapped to each lighting fixture, this software will adjust lighting levels as necessary based on occupancy or ambient light. In terms of the SAU, rooms such as the Davis dining area, which includes a number of windows, would benefit from this by having automatic light adjustments for each lighting fixture or fixtures. Those closest to the windows, would be reduced to a percentage of the maximum energy use and intensity. Moving inwards, lights would operate at higher percentages. Lights near areas of high daylight availability can be programmed for a maximum on percentage, for example 60%, to ensure that over‐lighting and unnecessarily wasted energy occurs. To perfect the desired levels and program the software, a series of light intensity measurements and tweaking would be required; but, once each is set, the benefits of reduced energy usage and low maintenance will be obvious. Figure F – Automated Logic Software, Sample Room Data

Page | 25


Automated Logic offers additional programs beyond that of the WebCTRL software, which is currently implemented in many of the campus buildings. The Eco‐Screen Sustainability Kiosk is one such tool; it showcases the “energy conservations and sustainability measures” using touch screen technology. It would allow students, faculty, or visitors to cycle through the behind‐the‐scene technologies that will operate to make the SAU a greener building. As should be evident from the figure below, the Eco‐Screen provides an interactive presentation of the building’s systems, customizable to show personalized RIT graphics. The kiosk will connect to the SAU’s WebCTRL building automation systems, and provide real‐time and historical energy data for monitoring by any passersby. The display will incorporate and show electricity usage, outdoor and indoor temperature and conditions, solar panel data, and HVAC information.

In addition to the energy savings from the implementation of higher efficiency lights and lighting solutions, and alternative energy systems, RIT will benefit from the use of WattStopper digital managements components and Automated Logic’s WebCTRL monitoring software. The monitoring of energy distribution, generation, and consumption through interactive displays hung in the central areas of the SAU will peak interest for energy conservation across campus. The key to reducing energy use and eliminating unnecessarily wasted energy, is to inform the RIT population and administrative faculty of that which occurs regularly. In order to properly manage usage, one must first be aware of the measurements. Implementing monitoring stations and software to track energy use and to alert of abnormal energy use instances is vital to understand RIT’s resource use. Identifying the unknowns and tracking changes can allow for continued energy efficiency improvement, beyond that of a simple lighting upgrade. Overall building performance will increase, and maintenance of technologies and components currently in use will drop drastically, through the use of the stated software and hardware.

Page | 26


As RIT actively strives to become a greener campus, through is continual improvements in technologies and practices across campus and environmentally friendly, recently built buildings, these proposed changes go hand‐in‐hand with RIT ideals. Stated on RIT’s sustainability page on their website, “RIT seeks to become a world leader in sustainability education, research, and practice.” This desire to create a more sustainable community through student innovations and creativity has been an ever increasing goal of the university. President Bill Destler signed the American College & University Presidents Climate Commitment back in 2008, and currently resides on its committee. Energy efficient initiatives and community interaction such as this follow suit with Rochester Institute of Technology’s drive to make a difference.

Schematic Estimate and Schedule

Cost Estimate

Using NECAWorks we were able to estimate the saving from our proposed lighting modifications. As seen in the appendix, the lighting accounted for about 30% of the electric bill and HVAC about 40%. Based on these assumptions we estimated that our upgraded lighting and lighting control systems would save on average 40% of the current kW/hrs. used and retrofitting the skylights with electrochromic glass glazing would cut the kW/hrs. used by the HVAC system by 20%.

Schedule Summary

Financing Plan

In order to consider this project to be successful several different components and systems need to be installed. These components and systems include the installation of:

LED lighting and fixtures New windows Digital lighting automation & management systems Wind turbines Photovoltaic Panels

There are several key points to keep in mind while creating a work/construction plan for the

SAU. This includes student and business activities and the local weather. Taking these into

consideration, most of the work will be performed during the warmer summer months. These

months is when most students are on either summer break or co‐op. Also projects such as

replacing the windows in the summer will have a lower impact on heating costs. Meanwhile,

installation of the lighting automation system can take place throughout the year. Please see

Outreach Content

Community Energy Awareness

RIT and its students have demonstrated a great commitment to ‘go green’ in the past few years. Through this commitment, awareness among the students and community has increased.

Within the couple of years RIT has built several new energy efficient buildings, one of which has achieved a platinum certification from the U.S. Green Building Council. This platinum rating is the highest standard that can be achieved in this rating system. RIT has also updated its lighting with LED lighting as discussed previously.

Students are involved in various clubs include the Electric Vehicle Team, Green Snowmobile, eBike Fleet Team, Engineers for a Sustainable World (ESW) and many others. Each of these groups helps promote conserving energy or use alternative energy resources.

Now how do RIT and its clubs help raise community awareness? Well, RIT is the proud host of an event called Imagine RIT. Imagine RIT is a campus wide event where students and clubs are able to set up exhibits to show off their projects and ideas while attending RIT. This event is free and open to the public. With over 30,000 people attending this event, this is the perfect place for RIT and its clubs to raise community awareness.

RIT’s NECA Green Energy Challenge team plans on working with the other clubs to raise awareness at next year’s Imagine RIT festival. To do this we will set up a booth which will contain detail of how the community member can conserve energy in their own home. This information can be from installing LED light bulbs to installing efficient windows. It will also have information on what the RIT NECA team completed and how we proposed to save energy through the past two years of challenges. We have proposed this idea to students and community members alike. One community member stated “I think it is a great idea to have a booth to inform the community at Imagine. A lot of people know that it is possible save energy and money by implementing different methods but do not necessarily know how to or they don’t think that it will be effective.”

Students develop tactics to make RIT’s Student Alumni Union ‘greener’

Energy efficiency ideas for national design challenge are incorporated into daily operations

May 5, 2014 by Michelle Cometa Follow Michelle Cometa on Twitter Follow RITNEWS on Twitter

Inspired by Rochester Institute of Technology’s focus on green technologies, some of its undergraduate electrical/mechanical engineering technology students are looking to make the university’s Student Alumni Union a greener place.

Their work is part of the Green Energy Challenge, a national student design competition sponsored by the National Electrical Contracting Association. Student chapters of the organization participate annually on a design project to do energy audits of power and lighting systems as well as detail how alternative energy systems can be incorporated into facilities.

RIT’s students submitted their plan for the campus’ Student Alumni Union to the association but also found that the work relates directly to campus initiatives to improve its carbon footprint.

Working closely with the university’s Facilities Management Services team, the students assessed current energy consumption in the different dining facilities and academic department offices to recommend ways to increase energy efficiencies in the widely used facility. In the past several years, FMS has transitioned many campus facilities to LED lighting and continually monitors environmental temperatures and energy usage in academic and residential buildings.

Page | 32


The student team wanted to take this further and worked with two FMS engineers, Dave Harris and Ryan Crittenden, to focus on the benefits of higher efficiency lights and lighting arrays as well as the installation of more motion-activated lighting sensors, and new arrays of photovoltaic panels on the roof and wind turbines outside the SAU.

“Some of the issues discovered with our preliminary analysis of the SAU were mainly found on the energy consumption uses,” said Shaun Henry, a fourth-year electrical/mechanical engineering technology student in RIT’s College of Applied Science and Technology. He is one of four students from the program on the project’s design team. “Despite the relatively large areas of glass to allow in natural lighting, a lot of light fixtures are kept on all day. Some cafe lights were also found on when the facility was not in use over the weekends. And glass panels currently in use may be the source of heat loss raising the need for additional heating during colder months.”

One of the products of the work being performed by the students will be a list of Energy Conservation Measures (ECMs), said Harris, director of FMS’ Training, Utilities, and Environmental Management. FMS will review the measures in terms of energy to be saved, reduced maintenance costs, first costs required to implement the measures and return on investment.

“The students wanted to know about the amounts of energy, both electrical and natural gas, the facility uses on an annual basis,” he added. “The building’s occupants have many different requirements on how space is configured and used. Identifying those different uses and their impact on energy is one of the many challenges the students faced when looking at the buildings energy profile.”

The team has since proposed to retrofit the remaining fluorescent lighting fixtures to LED technologies, as well as install additional occupancy and photo sensors throughout the building to reduce energy usage. They have begun formulating ideas to add photovoltaic panels and interactive energy monitoring stations to the area.

Working with the FMS engineers, the students gained insights into some of the technologies and software implemented in the recently completed Golisano Institute for Sustainability on the RIT campus. Some of these same technologies have the potential to significantly reduce wasted energy through customized programming for the SAU project—things as simple as area-specific sensors to provide adequate lighting for any time of day. The technology is available; it only needs those willing to make changes for the better, Henry said.

“This project is important because it gives us as students a chance to apply concepts we have been studying to an everyday necessity—lighting and energy use,” he adds. “We hope to provide the groundwork for a greener, more energy efficient campus, and hope to carry over our ideas when we finish here at RIT and go out into the world.”

The RIT team of Shaun Henry, Daniel Appiah Mensah, Charles Riggio and Joseph Repass, along with faculty advisor David Krispinsky, associate professor in the electrical, computer and telecommunications engineering technology program, will learn of results in July. If they are part of the group of finalists will present their findings at the NECA convention in Chicago in September.

Local NECA Chapter Interaction

RIT’s NECA team attended two Rochester, NY Chapter meetings on September 27, 2013 and April 25, 2014. About twenty NECA members were in attendance; it included NECA officers Peter Stoller, Executive Director of the Rochester (NY) Chapter, Vic Salerno from O’Connell Electric, Dan Streicher, Ken Lawrence and local electrical contractors. A few members of the NECA team also visited and toured the NECA JATC training facility in Henrietta, NY on December 11, 2013 along with 15 other engineering students from Rochester Institute of Technology. The training facility included a complete electrical photovoltaic system and electrical vehicle charging stations, used for instruction and training.

We had direct contact with Ed Schuler from Schuler Haas electrical contracting in Rochester. This involved corresponding with the vendor JACOMB Lighting where Bill Gauthier is President/CEO. JACOMB Lighting handles intelligent lighting controls systems from Encelium Lighting. The actual correspondence is given in this report in the Appendix section. Mr. Gauthier is willing to work with RIT’s FMS and the students involved with this proposal to install and implement demo control systems for energy efficient lighting here on campus. He has proposed we utilize digital lighting control systems by Encelium, which is an alternative to the WattStopper DLM systems. This would provide RIT with an opportunity for cost effective purchasing of their lighting management systems. It is feasible to create a customized management system that incorporates the best of all available technologies to create the most efficient energy saving system. Additionally, Mr. Gauthier has offered to take a few students on an information and training day, expenses paid, in order to aid in the development and implementation.

On the next page are the agendas from two Rochester NECA Meetings, wherein the team discussed

From: Bill Gauthier [[email protected]] Sent: Thursday, May 01, 2014 4:50 PM To: David Krispinsky Subject: RE: E Encelium Lighting Control System With 6 Strategy Dimming Technology & Graphics

Good afternoon Dave and thank you for your reply. If there’s any additional information that you or Ryan would need please don’t hesitate to ask. We’d be honored and excited to be able to install a demo Encelium system on your campus and with the NYSERDA incentives attached to it the economics would look good as well. Would you recommend that I contact Ryan directly for any further discussion or should I hold off for now? I don’t want to put any pressure on anyone but thought I’d ask just to be sure. Again I appreciate your feedback and look forward to talking again soon. Enjoy the rest of your day. Best regards, Bill Gauthier President/CEO JACOMB Lighting LED, Induction and Traditional Lighting, Intelligent Lighting Systems … From: Bill Gauthier [mailto:[email protected]] Sent: Thursday, May 01, 2014 6:12 AM To: David Krispinsky Subject: Encelium Lighting Control System With 6 Strategy Dimming Technology & Graphics Importance: High Good morning Dave, My name is Bill Gauthier and I’m the owner of JACOMB Lighting here in Rochester. I received your contact information from Ed Schuler at Schuler Haas. He attended a meeting last week at your NECA chapter meeting and said you spoke about Watt Stopper and their capabilities with lighting controls. He also mentioned that you’d be installing a demo system there on your campus for testing. I wanted to send you a bit of information on the Encelium Intelligent Lighting Control System. I think you’ll be pleasantly surprised with their approach and the capabilities of their system. We have local installation at St Ann’s Community where we incorporated 10 floors of resident, common area and office areas, Bausch & Lomb – 4 different phases, Rochester General Advanced Wound Center and Ralph Wilson Stadium where we just landed early first quarter the lighting controls for the stadium, new team store and team locker room/training facility. The St Ann’s project is currently saving approximately $200/day by utilizing the 6 strategy approach (daylight harvesting, occupancy sensors, task tuning, smart time scheduling, personal control and load

shed). They will be moving forward with another phase this year in the Nurse’s Admin Area and will continue to build the system out as funds permit. We’ve been working with NYSERDA closely to get our system approved for their new demonstration program where they’ll cover up to $150,000 not to exceed 60% of the total project cost. We’re looking for a 2nd location to put through this program. If you were interested in knowing more about Encelium and this program I’d be more than happy to set something up in the near future to help you become more familiar with the system. Our Polaris 3D software is the first in the industry to offer 3D graphics (see attached link with short video along with short 6 strategy video). Click on the two arrows in the middle of the page to view videos. http://www.encelium.com/ Ed Schuler’s team does all of our installations(Ferguson Electric for Ralph Wilson Stadium) and can vouch for how a system like this can make a significant difference. He also mentioned that he’d donate a few thousand dollars to get a site installation on your campus. This is how much he believes in the system. I could also offer up taking you and one or two others from your campus to the Osram/Encelium headquarters for a 1 ½ day training/overview of the entire system. All travel expenses would be paid for and it would be a very thorough and educational session. Please view the two short videos and feel free to contact at any time for additional information and/or discussion. I greatly appreciate you taking your time to review this information. I look forward to your reply. Have a great day.

There’s the energy savings a user captures by using

a particular lighting control strategy. Then there’s

the investment cost, which includes materials and

installation.

In literature and multimedia presentations, WattStopper

has developed an examination of ROI using many

assumptions. These are captured in this sales brief (see

page 2).

Cost-effective energy savings are the key. Many

companies can offer solutions that promise great

energy savings but ignore ROI. For customers today, the

real question is “How quickly can I get my investment

back?”

DLM boosts ROI by increasing energy savings, and

by reducing investment costs at the same time. For

instance, the ease of installation of DLM means

contractors can send even an apprentice to do the

installation and configuration. The elimination of highly

skilled installation labor helps reduces these costs.

An open office application, with its large number of plug

loads, offers an opportunity to leverage investments

in code-compliant occupancy sensors beyond

code mandates to increase ROI. This application is

highlighted in the Digital Lighting Management product

line brochure and the multimedia presentation, both

available at www.wattstopper.com/DLM.
