EXECUTIVE SUMMARY Background
Facilities Operations, through Energy Management, has been charged with the responsibility, together with the University Sustainability Office, to create energy conservation programs and to promote awareness through our Energy Campaign, by reaching out to students, faculty and staff. The Annual Energy and Water Plan Update is the roadmap used to monitor our progress to establish and guide objectives for the upcoming year. The Plan’s 5 focus areas are: Data Management, Energy Supply Management, Energy and Water Use in Facilities, Equipment Efficiency and Campus Integration.
GoalsIn 2007, the North Carolina General Assembly passed Session Law 2007-546
which states:• Energy consumption in all existing State buildings will be reduced by 20% by
the year 2010 and 30% by 2015 relative to Fiscal Year 2003.• All new State buildings will be 30% more efficient that ASHRAE Standard
90.1-2004.• All State agencies will develop a comprehensive plan to manage and report
their utilities to the State Energy Office and Department of Administration each #scal year.
• New water systems shall be designed and constructed to use a minimum of 20% less potable water than the indoor water use baseline calculated for the building after meeting the #xture performance requirements by the 2006 NC Plumbing Code.

MetricsDuring the course of each fiscal year, NC State Energy Management
monitors, tracks, and trends energy performance in its facilities. Along with traditional KPIs (e.g., Cost per GSF, BTU per GSF, Consumption per GSF), NC State tracked several additional KPIs in this year’s Annual Report: Weather Normalized Energy Consumption (BTU/GSF/DD), Utility Cost per Student, MMBTU per Degree Conferred, and MMBTU per Credit Hour Earned. Since the NC State student population is a major indicator of energy use on campus, these metrics are relevant, and show a decrease in energy use per student and energy use per academic degree conferred.
ConclusionsDuring FY2010, energy consumption decreased by 2% while the campus GSF
grew in size by 6%. Overall energy consumption trends show a reduction over time, and as the University gains more control over buildings’ energy performance through widespread metering, data management and outreach, the goal of 30% reduction compared to the 2003 Baseline is achievable. In fact, weather normalization shows a 10% decrease from FY2009 to FY2010.
Water reduction goals mandated by SL 2007-546 have been achieved. Total water consumption since FY2002 has steadily dropped, fueled by water-efficiency programs, outreach efforts, and past drought management efforts by the City of Raleigh, which have caused residual conservation efforts in the public domain. In FY2010 NC State has exceeded the 2015 Water Goal by an additional 30%.

INTRODUCTIONMission Statement
Facilities Operations, through Energy Management, has been charged with the responsibility to manage energy resources purchased and consumed by NC State in the most cost-effective manner. It is Energy Management’s responsibility, together with the University Sustainability Office, to promote energy conservation and awareness through our Energy Campaign, called Change Your State, and by reaching out to students, faculty and staff.
Vision StatementThe deployment of existing energy-efficiency and renewable energy
technology is the nearest-term and lowest cost option for managing our nation’s demand for energy, especially over the next decade. The potential energy savings available from the accelerated deployment of existing energy-efficiency technologies in buildings, transportation and industrial sectors could more than offset projected increases in energy consumption through 2030. Accelerated deployment of these technologies in the buildings, transportation, and industrial sectors could reduce projected energy use by about 15 percent.
National awareness of GHG emissions, most notably carbon emissions, has caused us to re-evaluate the future of energy supply by creating an increased demand for renewable and carbon-neutral energy solutions. For example, some of the energy supply methods include solar (active and passive), wind, hydro, nuclear, and biomass. The future depends on renewable energy, expansion and modernization of the Nation’s energy infrastructure and the ability to control our energy demand for efficient use of the power grid. All of these elements will work in tandem to provide a sustainable energy future and a decrease in greenhouse gas emissions.
The widespread implementation of energy-efficient and renewable technologies will also create substantial reductions in greenhouse gas emissions. NC State understands the impact it has on the environment through the creation of the Greenhouse Gas Inventory and Climate Action Plan. NC State completed its first biannual Greenhouse Gas Inventory in 2008 and is currently using that inventory to determine strategies for carbon abatement and reduction of GHG. It has been determined that the primary source of GHG emissions is our electricity demand.
Energy management has emerged as one of the most critical fields of study and professions of the current era. There are many aspects of the profession, and many different ways to approach current energy problems. The University’s energy management professionals and facility managers are equipped with a diverse skill set: technical and creative with the ability to understand the complex energy grid.
Public Policy • UNC-GA Sustainability Policy 600.61 – “e University of North
Carolina General Administration is committed to leading the State of North Carolina as an environmental steward that endeavors to proactively and effectively manage its impact on energy, water, and other natural resources.”
• N.C. State Legislature passed Senate Bills 668, 1946, and Session Law 2007-546.
- Energy consumption in all existing State buildings will be reduced by 20% by the year 2010, and 30% by the 2015 relative to #scal year 2002-03.
- All new State buildings will be 30% more efficient than ASHRAE standard 90.1-2004.
- All State agencies will develop a comprehensive plan to manage and report their utilities each #scal year to the State Energy Office and Department of Administration.
- New water systems shall be designed and constructed to use a minimum of 20% less potable water than indoor water use baseline calculated for the building after meeting the #xture performance requirements by the 2006 North Carolina Plumbing Code.
• N.C. State Legislature passed Session Law 2010-196 mandating. that all UNC-system schools keep 60% of utility savings resulting from energy conservation measures. e realized savings must only be used on additional energy saving measures for the University. Continually, the projects must not require additional funding from the State of North Carolina.

StaffIn Fiscal Year 2010, NC State Energy Management added manpower to its
ranks. Staff growth reached 9 full-time employees. The additional personnel has given Energy Management the opportunity to broaden its scope of services and to support its NC State partners’ strategies for data analysis and for implementation of ECMs.
Energy Management has also applied for and received grant funding totaling $778,000 for ECMs on campus. This fall, Energy Management will also add ten energy fellowships sponsored by the State Energy Office. The $478,000 grant is provided through ARRA funding and creates a partnership among Energy Management, FREEDM Systems Center, Sustainability Office, Solar Center and Advanced Energy. The fellows will work on synergy projects among the 5 partners to help deploy energy programs throughout NC State and the State of North Carolina.
Progress in FY2010FY2010 was a year of positive change for Energy Management. Highlights
include:• e partnership between the University Sustainability Office and Energy
Management was formalized. is partnership will support effective outreach programs.
• Two Energy Program Coordinator positions were funded and #lled.• Over $1.2 million in ARRA funding was awarded to NC State through
Energy Management's grant writing efforts.• NC State was selected to participate in a selective #eld of 14 competitors
in the Energy Star™ National Building Competition; thanks to Energy Management's leadership.
• A comprehensive University strategic energy management planning process was initiated.
These changes have laid the foundation for a brighter future for Energy Management at NC State.

HIGHLIGHTS AND ACCOMPLISHMENTS FOR FY2010Overview
Energy Management is charged with the responsibility to actively manage energy resources purchased and consumed by NC State in the most cost-effective manner. It is Energy Management’s responsibility, together with the University Sustainability Office, to promote energy conservation and awareness through our Energy Campaign by reaching out to students, faculty, and staff.
The annual Strategic Energy and Water Plan is the metric used to track progress and establish and guide objectives for the upcoming year. The Plan’s 5 focus areas include: Data Management, Energy Supply Management, Energy and Water Use in Facilities, Equipment Efficiency, and Campus Integration.
Data Management• Smart meters are devices capable of communicating real-time
consumption and demand data over the campus network for storage, analysis and billing. e integration of 20 additional smart meters into the University’s data systems enhances the ability to perform real-time assessment of metered areas. e interfaces provided by the smart meters is enabling the integration of other meters over the network that were previously unavailable for monitoring.
• e EBS database, the eDNA real-time database, and Crystal Reporting structures provide a base which enables the sharing of data to groups in the campus community and to provide support for campus data needs involving University resource use.
- In coordination with OIT staff, a data interface is provided to allow the sharing of data with a graduate student group for an on-going plant efficiency study.
- Billing data is provided to the ESCO responsible for the 13 Building Guaranteed Energy Savings Performance Contracting project to facilitate M&V for energy saving assurance.
• Data for the Intersession Setback Program is compiled and evaluated by the Building Committee to maximize potential energy savings while ensuring adherence to the University’s mission.
• Data was provided to the Packpulse System, a student developed interface, which used University data systems for web based monitoring capability of issues through the eyes of students. e Packpulse System was brought into the University intranet to provide added data and system security.
• e process to upgrade EBS billing software and the eDNA real-time web interface was completed early in the #rst quarter of FY 2011.
- e EBS upgrade provided support for the new business model related to the new established Utility Trust and additional features to the end user.
- e eDNA web upgrade provided the framework for an internal dashboard system to monitor available system data.

Tree Maps: A New Energy Analysis ToolThe Tree Map at right illustrates relative energy use by building and building
category. The tree maps are used to evaluate relative performance among buildings and to identify possible targets for energy conservation measures.
In the diagram shown here, each block represents a building’s chilled water use, and the color represents a building type or category. Comparing relative sizes of the blocks enables Energy Management to help determine where efforts are most likely to have an effect on the overall campus energy use. Chilled Water Utility Tree Map
Energy Supply ManagementThe purchase of fuels for NC State is evaluated monthly. This evaluation
compares purchasing transport natural gas monthly and in strip form against the purchase of Tariff natural gas. Monthly comparisons also include the advantage, if any, of using fuel oil in place of natural gas at locations where fuel oil is an alternative fuel.
Natural gas is a fuel where the price varies significantly, particularly if interruptions in the natural gas supply occurs. Significant increase in price occurred during Hurricane Katrina, when certain natural gas supply points in the Gulf of Mexico were interrupted. During FY2010, NC State developed a plan to improve contracts for the purchase of natural gas. The proposed contract change permits purchasing strips of any size with delivery of up to 1 year beyond the contract expiration date. Acquiring long-term natural gas strips will help ensure stability in the cost of natural gas consumed by NC State in the event of supply emergencies.
During FY2010, NC State successfully contracted the installation of a solar thermal system to heat domestic hot water and pool water at Carmichael Gym. The installation of this project, completed in November 2010, will be the first source of solar energy that will displace a portion of the natural gas consumed.
The cost effectiveness of rate schedules for electric accounts are also monitored. Energy Management compared savings between Time of Use rates and standard rates.
• e purchase of transport and strip natural gas, versus tariff natural gas and fuel oil, is evaluated monthly for interruptible and #rm natural gas accounts. Historically, transport and strip natural gas is the most cost-effective choice of fuels for the University. All of the larger accounts are on the interruptible rate; meaning that when PSNC exceeded capacity for #rm accounts, NC State switched to fuel oil. is process saved NC State $332,958 in FY2010 and more than $2.7 million since the program started in FY2003.
• In FY2010, the cost of fuel oil per British ermal Unit (BTU) was higher than natural gas. Additionally, fuel oil is corrosive to the interior of the boilers. For these reasons, it is not desirable to burn fuel oil, except during natural gas curtailments. PSNC realized capacity problems in January and February of 2010, and it became necessary for NC State to temporarily switch the interruptible accounts to fuel oil.
• Since 2002, several PEC electrical accounts were switched to Time of Use rate structures. ese accounts are reviewed annually for the cost avoidance. is year alone, $389,068 in savings were realized, totaling more than $1.1 million.
• Water consumption data continues to show considerable reduction in usage since the base year of FY2002. e continued use of water from Lake Raleigh for irrigation minimized the use of domestic water at NC State.

Water Saving InitiativesIn 2009, Utilities & Engineering repaired the heating hot water system at Reynolds Coliseum. To date NC State has saved more than 1.5 millions of gallon of water directly related to this repair, a 23% savings.
NC State has made a commitment to reduce its water consumption across campus, and part of this obligation is to use non-potable water for the cooling towers. Utilities & Engineering designed a system to capture two sources of non-potable water, rainwater from the roof and process water from the plant’s vacuum separator. ese two sources of water are currently replacing more than 100,000 gallons of water per month that would have been supplied by the City of Raleigh.
Energy Use in FacilitiesEnergy Use in Facilities applies to the efforts of Energy Management and
its partners to reduce the University’s energy consumption by targeting campus buildings that illustrate a high energy usage. Senate Bill 688 sets a standard for all State-owned facilities, and the measures below are intended to help NC State meet or exceed these standards. This focus area is divided into key sections that are described in detail in the Strategic Energy Management Plan document. The Plan includes topics from Performance Contracting to LCC and Repair and Renovation Grants for ECMs. The document is the roadmap that NC State will use to reduce campus energy consumption.
Some of the projects targeting facilities are listed below, others are listed in Table 1:
• Coordinate building setbacks during the holiday break with an estimated $55,000 in avoided costs compared to the baseline period of December 2004.
• Yarbrough Central Utility Plant uses a combination of rainwater and reclaimed water from the surface condenser vacuum pumps provides 6,000 gallons of water per day to reduce the cooling tower make-up demand.
• e 13 Building Performance Contract is underway, guaranteeing energy savings of more than $1.7 million per year.
Equipment EfficienciesNorth Carolina Executive Order 156 encourages all state agencies to
maximize their efforts to develop and implement environmentally sustainable policies and practices to minimize its impact on the environment and reduce their overall utility operating cost. The University’s commitment to reduce its GHG emissions has set forth various initiatives to maximize and jumpstart programs that are geared to the reduction of the campus’s energy consumptions. The following programs are some of the many strategies that the University is deploying to make certain we are keeping our commitment to the various agencies.
Programs include: Energy Star™ Procurement Policy, Incentives for Energy-Efficient Equipment, IT System Energy Equipment, Fume Hood Modernization, LCC for Equipment Upgrades, and O&M Best Practices. Table 1 shows the projects that BM&O staff focused on in FY2010 to reduce energy and operational cost.

The following are projects performed during FY2010:• 934 steam traps were surveyed across campus and identi#ed $207,917
yearly energy loss from steam leaks. e return on investment on the repair of the failed traps was less than 4 months. Defective Central Plant steam traps were replaced.
• Lighting upgrades at Jordan Hall replaced T12/34 watt lamps with T8/25 watt lamps to provide similar lighting levels with lower energy consumption.
• HID high-bay lighting #xtures in the Yarbrough Central Utility Plant were replaced with energy-efficient induction lighting. Induction lighting also provides an instant start, allowing the staff to use the lights within the mechanical room as-needed, increasing the energy savings.
e #xtures also lower maintenance costs due to an expected lamp life of more than 30 years.
• Energy-efficient lighting and occupancy sensors have been installed in the Butler Communications Building. e lower wattage lamps, coupled with occupancy sensors, increase energy savings in infrequently used corridors and common spaces.
• A pilot program for lighting upgrades was deployed in the stacks at DH Hill Library. e pilot program will help determine if lower wattage lamps provide acceptable light levels, visual comfort and energy savings to justify expanded deployment.

Energy Star™ National Building Competition - Tucker Residence HallTucker Residence Hall, a dormitory on the NC State Campus, was selected to participate in the U.S. Environmental Protection Agency’s (EPA's) #rst national competition among commercial buildings to save energy and #ght climate change. In the spirit of popular weight-loss competitions, Tucker Residence Hall will compete against 13 other buildings across the country to “work off the waste” through improvements in energy efficiency with help from EPA’s Energy Star™ program. e building that sheds the most energy waste, on a percentage basis, will be recognized as the winner of EPA’s National Building Competition in late October 2010. To add to the excitement, NC State’s rival UNC – Chapel Hill was selected for the competition as well.
”NC State University Housing is honored to be a part of the EPA National Building Competition,” said Barry Olson, Associate Director of University Housing Facilities. "We can’t wait to show how small changes can make a big difference when it comes to energy conservation. Our students are looking forward to winning the competition and continuing NC State’s dominance over Carolina on a national stage.”
Nearly 200 buildings applied to participate in the National Building Competition, which will judge the energy performance of the 14 #nalists from September 1, 2009 to August 31, 2010. e energy use of each building is being monitored with EPA’s online measurement and tracking tool, Portfolio Manager. Contestants will receive technical assistance from EPA as well as energy #tness advice from celebrity trainer, Bob Harper.
“Buildings of all shapes and sizes are saving money and energy with help from EPA and Energy Star™,” said Jean Lupinacci, Director of EPA’s Energy Star™ Commercial Buildings Program. “We applaud the contestants of EPA’s National Building Competition for taking action to protect the environment and #ght climate change.”
According to EPA, energy use in commercial buildings accounts for 17% of total U.S. greenhouse gas emissions at a cost of more than $100 billion per year. On average, 30% of the energy used in commercial buildings is wasted. ousands of businesses and organizations work with the EPA’s Energy Star™ program and are saving billions of dollars and preventing millions of tons of greenhouse gas emissions from entering our atmosphere each year.
Energy Performance ContractingAn EPC is a performance-based procurement method
and financial mechanism for building renewal projects whereby utility bill savings that result from the installation of new building systems (reducing energy use) pay for the cost of the building renewal project. A Guaranteed Energy Savings Performance Contract includes language that obligates the contractor, a qualified ESCO, to pay the difference if at any time the savings fall short of the guarantee.
Energy Security-EPC on a broad scale can make a significant contribution to the reduction of facilities energy demand state-wide and nation-wide. A recent engineering study concluded that a new NC State building-based performance contract investment of $18.3 million implemented over 5 years would achieve a simple payback of 6.1 years and save the University over $121 million over a 20 year term.
NC State has engaged Schneider Electric, an ESCO, to renovate and to implement ECMs in 13 buildings on campus. The first phase is currently underway, and the project is scheduled to be complete by the end of FY2011. All of the design and construction costs for the projects are included within the scope of the ESCO, so there is very little funding required up front by the University. In addition, measurement and verification of the guaranteed energy savings are within the scope of the ESCO. Table 2 outlines the ECMs being installed in the 13 buildings on campus shows the facility, capital cost, annual savings, and simple payback.
Campus IntegrationFY2010 established a new partnership between
Energy Management and the University Sustainability Office. The partnership's primary focus is to create a positive campus culture change. Activities include creating a network among existing campus sustainability-minded stakeholders to develop a social marketing and communications plan that promotes sustainability and energy conservation. Great progress was achieved through greater student, faculty, and staff collaboration and

engagement across the campus community. This included a comprehensive student survey, a high profile energy conservation awareness program, participation in a national energy conservation competition, and the pending designation of 2 dorms that are worthy of the Energy Star™ designation.
The outreach programs deployed in FY2010 include:• Energy Management and the Sustainability Office conducted a student
survey to assess the students’ understanding of sustainability issues on campus. e results of the survey showed:
- 85% think that it is important for NC State to be a leader in sustainability and the environment.
- 86% think that it is important for Americans to conserve personal use of energy.
- More than 85% think that it is important for NC State students to recycle the products they use.
- 76% of the students agree with the statement: “When I conserve energy, I contribute fewer greenhouse gases to the atmosphere.”
- 68% think that global climate change will be a major problem for future generations.
• Energy Management, Waste Management and Recycling, and the Sustainability Office created outreach advertisements to promote energy savings on campus. ese ads were placed in the Technician and on electronic bulletin boards across campus.
• Tucker Residence Hall was selected by the US EPA to compete in a National Energy Star™ Building Competition along with 13 other buildings across the country. e competition concludes this fall, and the residents of Tucker Hall are expected to be actively involved in an energy awareness campaign as the end of the competition approaches. Only one other university is in the competition.
• Beginning with the residence halls, energy usage data was entered into the Energy Star™ Portfolio Manager, which allows Energy Management to compare our buildings’ energy consumption to others nationwide. Energy Star™ designations for 2 residence halls, Sullivan and Carroll, are expected in FY2011. Energy Star™ Buildings perform in the top 25% compared to similar building types.
• e Energy Policy Act of 2005 provides a provision for non-taxpaying entities, like NC State, to take advantage of tax bene#ts for energy-efficient projects. Teamed with University Housing, Energy Management pursued these bene#ts for LED lighting renovations completed at Bragaw Residence Hall in 2009.

CHARTING NC STATE’S UTILITY CONSUMPTIONTracking Campus Utility Consumption and Distribution
Energy Management currently tracks utilities delivered to most buildings on campus including several research facilities. The department reports on utilities from vendors such as PEC and PSNC Energy as well as utilities provided to individual campus facilities from substations and thermal plants.
• Purchased Utility Accounts (Total 474): - 136 Electric- 101 Natural Gas- 137 Domestic Water/Irrigation
• NC State Utility Meters (Total 621):- 249 Electric- 84 Steam/Condensate- 193 City Water- 30 Domestic and Heating Hot Water- 65 Chilled Water
Utility meter data is entered into EBS utility billing software monthly. Historical information is tracked through the Oracle database implemented for the EBS system. The NC State meters are used primarily to monitor consumption by receipt-funded entities. Energy Management also uses this information to benchmark utility consumption for different building types (i.e., classroom, office, and laboratory) where metering information is available.
The report data is based mainly from supply side, or purchased utilities, by NC State. Data from sub-metering on the demand side is presented when available.

Steam Trap SurveyIn partnership with the State Energy Office, NC State performed a steam trap survey of the 5 Central Plants and many of the connected buildings. e goal of the survey was to determine the status of the steam distribution system, and to correct defects where they were identi#ed. Out of 934 traps surveyed, 133 traps were found defective, a 14% failure rate. is defect rate represents a signi#cant loss of steam from the distribution system, and an annual loss of $207,917 to the University. During the course of the survey additional traps were found plugged due to poor maintenance.
e simple payback to replace or repair the defective traps is less than 6 months. As a result of the survey, the University launched a Steam Trap Maintenance Program that will reduce both the defect rates and the associated energy loss. e preventative maintenance program makes the steam distribution system more efficient, which reduces the up-front cost to produce quality steam.
KEY PERFORMANCE INDICATORSAnnual Report Data
Each year NC State, along with all other universities and community colleges across the State, provides an Annual Report showing status of energy usage and progress toward short and long-term goals. Along with traditional KPIs (e.g., Cost per GSF, BTU per GSF, Consumption per GSF), NC State provided several additional KPIs in this year’s Annual Report, including Energy
Consumption per 1,000 GSF per DD, Utility Cost per Student, MMBTU per Academic Degree Conferred, and MMBTU per Credit Hour Earned. Since the NC State student population is a major indicator of energy use on campus, these metrics are relevant, and show a decrease in energy use per student and energy use per academic degree conferred. The baseline for energy reduction and water are highlighted in Table 4 below.

Table 4: Key Performance Indicators
TRENDS IN ENERGY AND WATER CONSUMPTIONEnergy and Water Consumption Metrics
The University made strides towards conservation goals by achieving a 2% reduction in energy use per square foot from FY2009. This reduction is noteworthy because new campus construction and renovation projects affected more than 1 million GSF in FY2010. The overall increase in energy use per GSF is less than 1% compared to the baseline.
Considering weather and temperature conditions in FY2010, there was a 10% drop in energy use per GSF per DD from the previous year. Additionally, as seen in Figure 2, there was a 2% reduction in energy use per GSF compared to the FY2003 baseline year.
Through continued commitment to the State of North Carolina’s reduction goals, the University achieved a 20% reduction in water use per square foot
compared to the FY2009 water usage. In comparison with the baseline year, there was an overall reduction in water use per GSF of slightly more than 43%.
Figure 2 shows NC State’s energy consumption compared to the State’s 2015 goal. Following several years of increased energy use, a decrease was achieved in FY2010. ECMs proposed for FY2011 will continue this trend.
Figure 3 shows NC State’s continued downward trend for water consumption. The 2015 goal of 20% reduction compared to FY2002 has been achieved.

Energy Management adopted additional KPIs for use in measuring progress. The metric in Figure 4 illustrates the relationship between energy use and academic mission. The metric for this KPI divides the total annual BTUs for the University by the number of degrees conferred by NC State. Since the BTUs used each year were substantial, the metric was derived by using units of millions of BTUs per academic degree conferred. Over the past 2 years the University has decreased energy consumption per academic degree conferred. NC State has reduced the total energy per academic degree conferred by nearly 3% from the peak value experienced in FY2008.
The weather in FY2010 was extreme, both high temperatures in the summer cooling season and lower temperatures in the winter heating season. To normalize energy consumption for weather conditions, a KPI relating energy use per GSF per DD is shown in Figure 5. Based on this metric, the University decreased BTUs/GSF per DD showing a reduction of 10% versus FY2009 and 2% versus the baseline year.

AVOIDED COSTS: RATE NEGOTIATIONSAnnual Policies for Energy Supply Management
Natural gas can be procured through the local supplier, PSNC (Tariff) or procured in bulk through energy marketers (Transport). The purchase of Tariff versus Transport is evaluated monthly for interruptible and firm natural gas accounts. Historically, procurement of bulk Transport natural gas is more economical than Tariff. The largest University natural gas accounts are on the PSNC interruptible rates. During periods of extreme cold weather, PSNC can interrupt the flow of natural gas, both Tariff and Transport sources. During
periods of natural gas curtailment, the campus switches to fuel oil to produce steam. The curtailment rate saved $332,958 in FY2010 and saved more than $2.7 million since the program started.
Like natural gas, electricity can be procured through different rate structures. Since 2002, many PEC electrical accounts have been switched to Time of Use rate structures. Energy Management reviews these accounts annually for cost avoidance opportunities. In FY2010, the University realized a savings of $389,068, totaling more than $1.1 million since the program’s inception.

LOOKING AHEAD TO FISCAL YEAR 2011Projections for 2011 and Meeting Goals for 2015
NC State is committed to reducing energy and water consumption and improving efficiency. The University will accomplish these goals in a manner consistent with campus needs for a safe, secure, and inviting campus community. Looking ahead to 2015, Energy Management is directing efforts and identifying strategies to accomplish stated objectives:
• Comply with legislative mandates for energy and water use reduction.• Meet the intent of the UNC System Sustainability Plan.• Support the NC State University Sustainability Plan and the NC State
Climate Action Plan.• Establish organizational and #nancial structures that will enable the NC
State Strategic Energy Management Plan implementation.• Evaluate required investments in capital and operating funds to realize
the mandated reductions and campus commitments.• Identify legislation or budgetary changes necessary to produce results.• Affect culture change at NC State to exemplify leadership in campus
energy-efficiency.By 2015, the University will produce reductions in energy and water
consumption with efficiency improvements through defined measures. The 5 focus areas are:
• Energy Data Management• Energy Supply Management• Energy Use in Facilities• Equipment in Facilities• Campus Energy Integration
Energy Data ManagementEnergy Data Management encompasses the entire effort involved in GHG
abatement and reducing the energy necessary to perform the daily operations of the University. Before changes can be made to any system, it is necessary to know what needs to be changed. As stated by International Quality Advisor,
21
US EPA Energy Star™ ParticipationBuilding ratings and energy assessments are valuable tools to compare NC State campus’s building energy use to other comparable campuses. ese comparisons enable the University to learn from other participating organizations and also promote successes. NC State has made a commitment to become an US EPA Energy Star™ partner organization, and as such, is making an effort to participate in the Portfolio Manager, EPA’s online tool, to certify buildings and to award the Energy Star™ designation.
An Energy Star™ facility meets strict energy performance standards set by the EPA and uses less energy, is less expensive to operate, and causes fewer GHG emissions than its peers. e EPA rating system accounts for differences in operating conditions, regional weather data, and other important considerations. To qualify for the Energy Star™ designation, a building or
manufacturing plant must score in the top 25 percent based on EPA's National Energy Performance Rating System. A rating scale of 1-100 is used to compare energy use among similar type facilities. Buildings that achieve a score of 75 or higher may be eligible for the Energy Star™.
At this time, residence halls are the only NC State campus building types speci#cally considered in the Portfolio Manager system. Most of the University’s residence halls’ energy information has been uploaded into the system, and two dorms are in the process of receiving the Energy Star™ designation. In FY2011 , NC State will expand its partnership with Energy Star™.
Dr. H. James Harrington, "Measurement is the first step that leads to control and eventually to improvement. If you can't measure something, you can't understand it. If you can't understand it, you can't control it. If you can't control it, you can't improve it." Energy Data Management aligns with the University goals of efficient management of resources while mitigating the related costs. This focus area is divided into 8 key sections which direct endeavors around the Energy Data Framework. The sections are described below:
• Predict Impacts of Growth: Using key performance indicators, relevant data is used to provide a long range plan based on modeling to project forward factors that affect energy consumption and then frame actionable items accordingly.
• Goals for Plan Sectors: Challenging benchmarks are set to prioritize energy reduction and carbon abatement strategies to further the University’s mission.
• Building Assessments: Leveraging Energy Star™ as an additional analysis tool, buildings are evaluated against normalized models. By determining norms, key energy users are identi#ed for projects to maximize efficiency and minimize energy use at the building level.
• Campus Automation Master Plan: e expansion of monitoring and control capabilities produces the ability to take an approach from a system perspective. is provides Energy Managers with the tools to perform load shifting and shedding to bene#t the University #nancially.
• Energy Dashboard: is multi-faceted solution empowers all University groups with varying levels of ability to steer energy reduction and carbon abatement.
• Metering Long Range Plan: Standards are set forth to provide metering with real-time capabilities to support monitoring, analysis, and enterprise billing needs.
• Trend Reporting: Strategies are developed for the production of intuitive reporting to facilitate management decisions towards exceeding existing and future reduction goals.
• Annual ROI Tracking: Yearly reporting strategies are provided to demonstrate savings realized from Energy Conservation Measures. is will act as a catalyst to promote additional energy conservation projects.
Energy Supply ManagementThe energy types used by NC State to heat and cool buildings are
electricity, natural gas, and fuel oil. Natural gas and electricity are the major energy sources. Energy Supply Management refers to how NC State procures these energy types by the most efficient means possible.
• Combined Heat and Power Program: Combined heat and power, also known as cogeneration, is a way to increase the efficiency of power plants. A 11.5 megawatt natural gas combustion cogeneration facility is planned for NC State.
• Utility Enterprise: A University Utility Enterprise, Wolf Energy, is a recharge cost center that sells energy and services to the campus to fund a utility trust account. Under the Utility Enterprise, all campus entities would be metered and receive a monthly bill for utilities consumed.
• Central Plant Optimization: Central Plant Optimization addresses the relation between the energy consumed by a piece of equipment to the chilled water and steam produced. Efficiency can also be measured by the ratio of operational cost to the utilities supplied by the plants.
• Electrical Demand Management: Electrical Demand Management entails actions that in&uence the quantity, or patterns, of energy consumed by NC State. DSM actions target speci#c activities to reduce the peak demand when energy supply is constrained and kW cost is high, which saves money.
• Energy Purchase Optimization: NC State has programs in place to acquire energy, electricity, natural gas and fuel oil at the lowest costs possible. Energy professionals review electrical rates, or tariffs, to ensure electricity is supplied at the lowest cost.
• Renewable Portfolio: Renewable energy sources are those which come from natural resources such as sunlight, wind and geothermal heat, which are rapidly and naturally replenished. NC State currently has
22
Combined Heat and Power SystemWhen electricity is generated by burning fuel or gas, one of the byproducts is heat. In a conventional system, waste heat is vented to the atmosphere. Using a more modern generation system, the waste heat can be captured and used for space heating and hot water. Because of its ability to utilize the waste heat, a CHP system offers a greater efficiency over standard electricity and heating systems.
NC State is studying the economic feasibility of installing a CHP system within the Cates Central Utility Plant on Main Campus. When commissioned, the CHP system will generate 11.5 MW of power, approximately one third of the University’s base electric load. e captured waste heat will be used to produce steam to be distributed throughout Main Campus within the existing steam system.
several small-scale solar thermal and solar PV systems on campus, and have several larger systems in the planning stages.
• Industry Best Practices: Best practices can be de#ned as the most efficient (least amount of effort) and effective (best results) way of accomplishing a task, based on repeatable procedures that have proven themselves over time for large numbers of people.
• Innovative Arrangements: NC State relies upon traditional utility #rms for energy. Currently, alternative energy sources require tax incentives, carbon credits, accelerated depreciation, or renewable energy credits to be cost-effective.
• Reinvestment Legislation: In the Summer 2010 Session of the North Carolina General Assembly, House Bill 1292 was rati#ed and became Session Law 2010-196. is Session Law allows all UNC system schools to keep 60% of savings resulting from energy conservation measures to be used solely for future energy saving measures.
Energy Use in FacilitiesEnergy Use in Facilities applies to the efforts of Energy Management to
reduce campus energy consumption by targeting campus buildings and the way that they are designed, built, and occupied. Senate Bill 688 sets a standard for all State-owned facilities, and the measures below are intended to help NC State meet or exceed these standards. This focus area is divided into 12 key sections which allow Energy Management to support its mission to reduce campus energy consumption.
• Organization for Success: e Energy Management Plan is the roadmap to establish objectives and guide activities. e proper utilization of this
plan allows NC State, to accomplish the far-reaching goals of energy efficiency and carbon neutrality.
• Energy Performance Contracting: Performance Contracting allows NC State to perform ECMs with minimal cost up-front. An ESCO #nances these projects which provide guaranteed energy savings.
• Retro-Commissioning: Retro-commissioning projects are completed in existing buildings to ensure that all building systems are operating as they should considering their current use.
• Building Conservation Incentives: Occupant behavior change is the primary target of Conservation Incentives. ese can take the form of a bonus for conservation or a penalty for wasting resources.
• Space Utilization and Scheduling: Space Utilization and Scheduling optimizes occupancy rates so that unoccupied buildings can be “shut down” to conserve energy.
• Intersession Energy Savings Initiative: During breaks, unoccupied buildings will have setpoints adjusted to provide energy savings.
• LEED Silver Design Standard: e LEED Silver Design Standard is a certi#cation provided by the United States Green Building Council and rewards the achievement of design and construction of an energy-efficient building or renovation.
• LCC for Capital Decisions: Incorporation of ECMs and energy efficiency into the decision-making process for capital decisions helps to gain a full understanding of total cost of ownership for a building or renovation project.
• Building Automation Master Plan: NC State integrates campus BAS systems into a single system.
23
Reinvestment Legislation - Session Law 2010-196In the most recent session of the North Carolina General Assembly, House Bill 1292 was rati#ed by the assembly and became Session Law 2010-196. Sponsored by Representatives Price, Womble, Jeffus, and Lucas SL2010-196 mandates that all UNC-system schools keep 60% of savings resulting from energy conservation measures. e realized savings must only be used on additional energy saving measures for the University. Continually, the projects must not require additional funding from the State of North Carolina.
In one prime example, a savings guaranteed to the University through the 13-building performance contract is roughly $20 million over 20 years. Potentially, the University could retain $12 million over that period of time. Needless to say, the impact of this legislation has not yet been fully discovered.
When considering the Climate Action Plan, Session Law 2010-196 impacts green power purchasing and all energy conservation measures.
• Public Utility Incentives: Public utilities are required to provide incentives for renewable energy and energy-efficient projects for their customers. e incentives (or penalties) are assessed based upon usage. e incentives address overall energy efficiency programs, as well as programs that reduce peak demand during high load times of the year.
• Repair and Renovation and Grants for ECMs: Energy Management and BM&O pursue funding opportunities for ECMs.
Equipment EfficienciesNorth Carolina Executive Order 156 encourages all state agencies to
maximize their efforts to develop and implement sustainable policies and practices to minimize their impact on the environment and reduce their overall utility operating cost. The University’s commitment to reduce its greenhouse gas emissions has set forth various initiatives to maximize and jump start programs that are geared to the reduction of the campus’s energy consumptions. The following are snapshots of programs and policies that are being implemented by the University.
• Energy Star™ Procurement Policy: e University is developing policies to guide departments to invest in energy-efficient equipment and demanding suppliers to provide the University with Energy Star™ Certi#ed equipment.
• Incentives for Energy-Efficient Equipment: e University is providing incentives to the campus community to replace old and energy inefficient equipment. e goal is to reduce its electrical demand and operational cost.
• Energy-Efficient IT Systems: e information hardware system consumes a great deal of energy to maintain and operate its
infrastructure. OIT is developing programs and performing energy data analysis to help reduce its energy consumption. Virtual computing is one of the many programs that OIT is implementing to reduce the number of servers and computers in use on campus.
• Equipment Energy Awareness Programs: e University has scores of fume hoods that support the scientists in their quest for answers through research. Fume hoods consume large amounts of energy, and the University addresses that problem via a fume hood modernization program. e program will help to replace the existing constant air volume fume hoods with variable air volume fume hoods.
• LCC for Equipment Upgrades: e LCC is the total cost of ownership of machinery and equipment. e University is studying LCC to choose the most cost effective machinery and equipment from a list of alternatives to achieve the lowest long-term cost of ownership.
• O&M Best Practices: O&M Best Practices are a set of standardized operating procedures that focus on safety and minimize unnecessary waste. O&M Best Practices is unique to each organization, yet similar in nature. Each entity uses its own Computerized Maintenance Management Systems. NC State uses Facility Focus to track and maintain its inventory, which is in excess of 15,000 pieces of equipment.
Campus IntegrationSaving energy and reducing the University’s carbon footprint requires the
buy-in of the entire campus community. By and large, building occupants drive building energy consumption. By establishing an energy policy and implementing effective outreach programs, NC State will achieve its aggressive energy reduction and GHG goals. Through the following strategies, Energy Management will lead the University toward its goal to reach 30% energy reduction by 2015.
• Comprehensive Energy Policy: An Energy Policy will enable NC State to address issues of energy development and use, including energy production, distribution and consumption. It institutionalizes energy goals and authorizes actions so that programs achieve campus-wide compliance.
• Sustainability/Energy Outreach: An effective outreach program called Change Your State will yield a high rate of ROI for

Fuel Oil Consumption in FY2010During FY2010, PSNC mandated NC State burn fuel oil to operate natural gas equipment for producing distributed steam. The increase in fuel oil consumption was due to cost mitigation strategies through NC State’s interruptible PSNC natural gas accounts. PSNC requires NC State to maintain an alternate fuel source on site to operate natural gas equipment during high demand periods for lower rate eligibility. While the University secured substantial avoided costs through the use of this method, using fuel oil increased the energy “overhead.” Because of the dramatic increase in DD, the University experienced a record-setting two weeks of natural gas curtailment. Fuel oil procurement increased tenfold due to the curtailment periods.

• Student Conservation Fee: NC State is one of the few large campuses in the UNC system without some type of student fee for sustainability. Students at the University of North Carolina at Chapel Hill, Appalachian State University, and University of North Carolina at Wilmington have an approved green fee.
• Student Work/Learn Opportunities: e college educational experience is evolving to become more closely tied to the real-world experiences. From energy awareness to green building best practices, students are seeking opportunities for engagement in learning more about the campus infrastructure. Student Work/Learn Opportunities explore how NC State can link the operations of the University with learning opportunities.
• Living Laboratories: Many universities use living laboratory opportunities to learn about infrastructure development and operation. Peer institutions often use infrastructure upgrades and renewable energy installations to educate their students, recruit faculty, and attract research grants. Similar opportunities exist at NC State. is component provides a roadmap to leverage these backyard learning opportunities.
• Centennial Partner Engagement: e Centennial partnership offers a special opportunity to #nd common ground between the University and businesses. By engaging public-private partnership by adopting sustainable and energy minded practices, the Centennial Community will bene#t as a whole, including the #nancial bottom line. e Centennial partnership engagement initiative presents a way forward.

THE STRATEGIC ENERGY MANAGEMENT PLANEnergy Management Charge
The current and continuing economic downturn facing North Carolina and NC State will continue to challenge us financially for the next several years. It is essential that NC State continues to explore every possible action to reduce operating costs, especially in the University’s non-core areas. Facilities Operations and Energy Management need to look toward new and different methods for conserving energy and reducing utility costs; therefore, this Strategic Energy Management Plan is required to provide a roadmap to achieve our goals.
The purpose of the Strategic Energy Management Plan is to reduce energy consumption and improve energy efficiency on the NC State campus consistent with the needs for a safe, secure, and inviting campus community. This is to be accomplished by developing 41 methodical and aggressive approaches for efficient energy use.
Each of the 41 Strategic Energy Management components follow the same format:
• General Description – What is proposed? • Business Case – Why are we doing this? • Primary Task Breakdown – How will it be accomplished? • Interactions Required – Who needs to be involved? • Resources Required – What is the cost? • CAP – How does this help the campus achieve climate neutrality?
The general goals of the Energy Management Strategic Plan are to: • Implement strategies to comply with legislative mandates for energy and
water use reduction. • Meet and exceed the intent of the UNC System Sustainability Plan. • Support and complement the campus Sustainability Strategic Plan and
the campus Climate Action Plan. • Establish organizational and #nancial structures that will enable the
Plan. • Evaluate required investments in capital and operating funds to realize
the mandated reductions and campus commitments. • Identify enabling legislation or budgetary changes necessary to produce
results. • Modify the culture at NC State to exemplify leadership in campus energy
efficiency.The 41 components of the plan are divided across 5 program areas:• Energy Data Management• Energy Supply Management• Energy Use in Facilities• Equipment Efficiency• Campus Energy IntegrationEach plan component will be further developed and prioritized to help aid
implementation. The plan will be updated each year to mark progress and adjust priorities.
