EXECUTIVE SUMMARY - FISCAL YEAR 2011UPDATE FOR FY 2010-11Fiscal Year 2010-11 was a very successful year for North Carolina State University. Th e University realized a 1-year 5% decrease in its key performance metric, BTU/GSF. Th is dramatic 1-year change moved NC State from the State Energy Offi ce (SEO) classifi cation for UNC institutions of “BTU/GSF greater than target with use increasing” to “BTU/GSF greater than target with use decreasing.” Other energy and water highlights follow.• Compared to the FY 2002-03

baseline, total energy consumption (BTU/GSF) has dropped 5% in 1-year (Figure 1).

• If weather normalization is considered, total energy consumption (BTU/GSF/DD) has dropped 8% compared to last year and 10% compared to the FY 2002-03 baseline (Figure 2).

• Water consumption (Gallons/GSF) has dropped 47% compared to the FY 2001-02 baseline and 7% compared to last year.

• Utility cost ($/GSF), including purchased electric, natural gas,

fuel oil and water, has increased by 21% compared to the FY 2002-03 baseline, but it has dropped 5% compared to last year. It should be noted that NC State added over 1.6 million GSF to campus last year.

GOALSIn April 2011, NC State published its strategic sustainability plan entitled Foundation for Advancing Sustainability: A Strategic Plan for NC State University. Th e Plan lists 7 strategic energy and water conservation goals.1. Achieve a 30% reduction in building

energy consumption by 2015 against the 2003 baseline.

2. Achieve a 50% reduction in building water consumption by 2015 against the 2002 baseline.

3. Improve energy data management capabilities and make data driven decisions utilizing enhanced energy data.

4. Train and educate staff and building end-users to properly operate and maintain building systems in an energy effi cient manner.

5. Ensure a cost-eff ective and reliable energy supply by developing business scenarios and strategies for

diversifying fuel sources.6. Evaluate utility fi nancial structures

that create incentives for saving energy.

7. Implement green standards and practices for information technology and computing.

METRICSDuring the course of each fi scal year, NC State Energy Management monitors, tracks, and trends energy performance in its facilities. Along with traditional Key Performance Indicators (KPI) (e.g., Cost per GSF, BTU per GSF, Consumption per GSF), NC State continued to track several additional KPIs in this year’s Annual Report: Energy Consumption per 1,000 GSF per 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.

CONCLUSIONBased on trend analysis by Energy Management, there is a statistically signifi cant positive relationship between campus growth and utility cost. As the campus grows with new buildings and building additions, our utility costs rise in lockstep, except for the last 3 fi scal years. Th e cost of utilities are on the rise and the campus continues to grow. If NC State was on the same trajectory for FY 2002-03 through FY 2008-09, total utility costs would be approximately $39 million per year; however, total utility cost has remained fl at at $32 million per year. Taken in combination, maintaining professional energy management programs and building high-performance new buildings have arguably saved the University $7 million per year in avoided utility costs (Figure 5). Th e continued implementation of the Foundation for Advancing Sustainability: A Strategic Plan for NC State University, which includes the Climate Action Plan and the Strategic Energy Management Plan, will ensure that NC State will meet the FY 2014-15 goal of reducing energy by 30%.

INTRODUCTIONENERGY MANAGEMENTOne defi nition of energy management is the sum of measures planned and carried out to achieve the objective of using the minimum possible energy, while comfort levels of building occupants is maintained. Th is task can be daunting due to 100 years of campus growth, ever-changing demographics, and a campus community with specifi c and critical needs. At NC State, Energy Management is the unit that tracks and forecasts energy from the consumption of the central utility plants through the energy consumption at each building, balancing the requirements of the University in the face of rising energy costs and complicated delivery systems.

MISSIONTh e mission of Energy Management is to manage energy resources purchased and consumed by NC State in the most cost-eff ective manner possible, while supporting the complex needs of this research intensive campus. It is Energy Management’s responsibility, together with the University Sustainability Offi ce, to promote energy conservation and awareness through our energy campaign embodied in the Change Your State website, and by continually reaching out to students, faculty, and staff at every opportunity.

VISIONTh e deployment of existing energy effi ciency and renewable energy technology is the nearest-term and lowest cost option for managing our nation’s demand for energy, especially over the next two decades. Th e potential energy savings available from the accelerated deployment of existing energy-effi ciency technologies in buildings, transportation, and industrial sectors could more than off set projected increases in energy consumption through 2030. Accelerated deployment of these technologies could reduce projected energy use by about 20%.

National awareness of greenhouse gas (GHG) emissions, most notably carbon emissions, has caused NC State 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. Th e future depends on renewable energy, expansion and modernization of the Nation’s energy infrastructure, and the ability to control our energy demand for effi cient use of the power grid. All of these elements will work in tandem to provide a sustainable energy future and a potential decrease in GHG emissions.Th e widespread implementation of energy-effi cient and renewable technologies will also create substantial reductions in GHG emissions. NC State understands the potential impact it has on the environment through the creation of the GHG Inventory and Climate Action Plan. NC State completed its fi rst bi-annual GHG Inventory in 2008 and used that inventory to determine strategies for carbon abatement and reduction. Th e Climate Action Plan, published in December 2010, projects a 20% GHG reduction from 2008 emissions by 2015. Th e focus of the next 5 years is on energy conservation and fuel mix/ renewables.

GOALSIn April 2011, NC State published its strategic sustainability plan entitled Foundation for Advancing Sustainability: A Strategic Plan for NC State University. Th e Plan lists 7 strategic energy and water conservation goals.• Achieve a 30% reduction in building

energy consumption by 2015 against the 2003 baseline.

• Achieve a 50% reduction in building water consumption by 2015 against

the 2002 baseline.• Improve energy data management

capabilities and make data driven decisions utilizing enhanced energy data.

• Train and educate staff and building end-users to properly operate and maintain building systems in an energy-effi cient manner.

• Ensure a cost-eff ective and reliable energy supply by developing business scenarios and strategies for diversifying fuel sources.

• Evaluate utility fi nancial structures that create incentives for saving energy.

• Implement green standards and practices for information technology and computing.

METRICSDuring the course of each fi scal year, NC State Energy Management monitors, tracks, and trends energy performance in its facilities. Along with traditional Key Performance Indicators (KPI) (e.g., Cost per GSF, BTU per GSF, Consumption per GSF), NC State continued to track several additional KPIs in this year’s Annual Report, Energy Consumption per 1,000 GSF per degree day (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.

PUBLIC POLICYIn North Carolina, all the public educational institutions that grant baccalaureate degrees are part of the University of North Carolina system. Th e multi-campus state university encompasses 16 such institutions, as well as the NC School of Science and Mathematics, the nation’s fi rst public

9

residential high school for gift ed students. As such, the University is regulated by its Board of Governors, and the NC State Legislature. Public policy specifi cally focused on energy includes the articles listed below:• UNC-GA Sustainability Policy

600.61 – “Th 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 eff ectively manage its impact on energy, water, and other natural resources.”

• NC State Legislature passed Senate Bills 668 and 1946 stating:

~ Energy consumption in all existing State buildings will be reduced by 20% by the year 2010, and 30% by the year 2015 relative to fi scal year 2002-03.

~ All new State buildings will be 30% more effi cient than ASHRAE standard 90.1-2004.

~ All State agencies will develop a comprehensive plan to manage and report their utilities each fi scal

year to the State Energy Offi ce and Department of Administration.

~ 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 aft er meeting the fi xture performance requirements by the

2006 North Carolina Plumbing Code.

• In July 2010, the NC State Legislature passed General Statute 143-64.12(a) mandating that 100% of energy savings resulting from ECMs at all UNC system schools are to be returned to the subsequent fi scal year utility budget. In addition, 60% of the savings are mandated to be applied to future ECMs, thereby creating funds for a revolving energy savings program.

With the assistance of Energy Management, NC State Facilities Division submitted a claim for more than $1.1 million to the NC State Energy Offi ce and the NC Offi ce of Budget and Management. Th is claim

was the only one submitted by any of the UNC system schools, and has become the standard template for future claims.

ENERGY MANAGEMENT STAFFEnergy Management at NC State is comprised of 23 full-time staff , led by the Energy Program Manager. Energy Management provides a critical role in managing and maintaining the metering system on campus.Additionally, 2011 welcomed 10 new energy fellows funded through an American Recovery and Reinvestment Act (ARRA) grant awarded by the NC State Energy Offi ce. Th ese 10 Energy Management fellows are working in pairs with 5 organizations to develop synergy projects and to increase discussion among the diverse campus community. Th e partner organizations joining with Energy Management on this energy fellowship project are:• University Sustainability Offi ce,• NC Solar Center,• FREEDM Systems Center/ATEC, and• Advanced Energy.2011-12 brings Energy Management 3 new, grant-funded positions, 1 Energy Manager and 2 Energy Analysts. Th ese positions will work as a team to conduct energy audits across campus, with the goal of identifying ECMs with short payback periods and having a big impact on the building energy consumption on campus. In addition, 2 of the energy fellows have contributed to the building assessment program.

HIGHLIGHTS AND ACCOMPLISHMENTS FOR FY2011OVERVIEWAt NC State, the role of Energy Management is to actively manage energy resources purchased and consumed by the University in the most cost-eff ective manner. Th e Strategic Energy and Water Annual Report is a compilation of the metrics used to track progress, and to establish and guide objectives for the upcoming fi scal

year. Th e Annual Report enables the NC State Energy Offi ce to monitor energy consumption at each of the UNC system schools and to track the schools’ performance toward the goals of North Carolina Session Law 2007-

546 entitled Energy Conservation in State Buildings. Th is law establishes “specifi c performance criteria and goals for sustainable, energy effi cient public buildings.” Th ese goals require the UNC system schools to reduce energy consumption by 30% compared to FY 2002-03 and water consumption by 20% as compared to FY 2001-02. Th ese goals are to be met by the end of FY 2014-15. To date, NC State has achieved a 5% reduction in overall energy consumption, and a 47% reduction in overall water consumption.Th is Annual Report’s 5 focus areas include Data Management, Supply Management, Energy Use in Facilities, Equipment Effi ciency, and Campus Integration.

DATA MANAGEMENTSmart meters are devices capable of communicating real-time consumption and electric demand data over the campus network for storage, analysis and billing. Th rough the integration of 24 new smart meters in FY 2010-11, the University’s ability to perform real-time assessment of metered areas is enhanced. Th e expandable interface provided by the new smart meters enables the integration of other meters over the network that were previously unavailable for monitoring. Th e data sharing capabilities for these devices also paves the way for development and implementation of “Smart Grid” technology. Th e EBS database, the eDNA real-time database, Crystal Reporting, and JMP Statistical Analysis soft ware packages allow the sharing of the data to groups in the campus community and to provide support for campus data needs involving University resource use. • Th e process to upgrade EBS billing

soft ware and the eDNA real-time web interface was completed early in the fi rst quarter of FY 2010-11.

• Th e EBS upgrade provides support

for the new business model related to the newly established Utility Trust and additional features to the end user.

• A method for external vendor utility billing has been created to sync with the University master accounting system.

• Th e eDNA web upgrade provides the framework for an internal dashboard system to monitor real-time energy data.

• Utility data is provided to the Energy Service Company (ESCO) responsible for the 13 Building Guaranteed Energy Savings Performance Contracting project to facilitate measurement and verifi cation (M&V).

• An eDNA web interface is provided to the ESCO for M&V tracking at the utility meter level.

• Data for the Intersession Setback Program is compiled and evaluated by Energy Management to maximize potential energy savings.

• Th e framework for an internal dashboard has been developed and a small number of dashboards have been created to meet customer needs.

• Utility data exception reporting has been expanded to better address issues of concern in the utility process.

• All campus utility meters were evaluated and analyzed. A long-range utility meter plan is being developed to provide a comprehensive meter modernization roadmap.

SUPPLY MANAGEMENTTh e purchase of fuels for NC State is evaluated monthly. Energy Management monitors natural gas prices during each month for an opportunity to purchase cost-eff ective strips (bulk purchases) of natural gas which provide for budget certainty and cushion against price spikes resulting from extreme weather events.

THE FIRST STEP FOR ENERGY CONSERVATION

Utility metering at NC State is going through a major change. Smart grid technology will revolutionize how utility distribution systems are operated resulting in signifi cant energy conservation. Th e term smart meter oft en refers to a two-way telecommunication enabled electrical meter, but it can also mean any network connected device measuring and reporting any type of utility consumption.

Energy Management is developing and deploying a long-range plan to install smart neters throughout campus. Th is will allow Energy Management and the campus community to have real-time access to energy consumption data. Analysis of this data enables us to identify and solve distribution problems faster. Th e promise of smart metering technology enables real-time pricing of utilities based on peak demand; thereby, greatly reducing energy consumption and cost.

the end of each fi scal year, Energy Management compares the prior monthly purchases of transport natural gas against the purchase of tariff natural gas and fuel oil. Th is comparison is useful in making the annual decision to use transport or tariff natural gas, which can be made only once per fi scal year. Th e price of natural gas may vary signifi cantly, particularly if interruptions in the natural gas supply or distribution occurs. During FY 2010-11, the variations in the price of natural gas at the wellhead (NYMEX Henry Hub) were moderate. Th e NYMEX price varied from $3.292 to $4.774 per decatherm. However, unusually cold weather during December and January resulted in curtailments, and NC State needed to switch to fuel oil on certain

interruptible accounts at the Central Utility Plants (CUPs). In FY 2010-11, the unusually cold weather aff ected the marketer’s distribution costs, primarily relating to pipeline capacity supplying natural gas to NC State. Th e natural gas marketer requested a 77% increase in the basis cost or marketing fee. As a result of this unexpected cost from the marketer, Energy Management and NC State Purchasing are reviewing the benefi ts of using an energy risk management consultant to assist NC State with preparing contracts and managing purchases of natural gas. Final FY 2010-11 evaluations show the purchase of transport and strip natural gas, versus tariff natural gas resulted in overall savings of $471,241. Th ese

savings, combined with a savings of more than $3,204,282 since the inception of the program, support the continuation of this procurement strategy. Th e cost eff ectiveness of rate schedules for electric accounts was evaluated. Energy Management worked with Progress Energy to record the savings from using Time of Use (TOU) rates verses Large General Service (LGS) rates. Th is evaluation informed the decision to switch additional qualifying accounts to the TOU rate in FY 2010-11.Water conservation has continued to be a strength of the NC State campus community. Th e water consumption for FY 2010-11 dropped by an additional 5% from FY 2009-10, and the 20% reduction by 2015 (see Session Law 2007-546, above) has been achieved. Th e stretch goal of 50% reduction by 2015 is well within reach.NC State continued with various ECMs during the year, which included lighting and HVAC improvements related to the 13-Building Performance Contract. Th e completion of this work reduces the purchases of electricity, natural gas, and water.In FY 2010-11, NC State was the only UNC system school to participate in reporting for the new Reinvestment Legislation, GS143-64.12(a). Th is legislation mandates that energy savings tied to ECMs installed during FY 2010-11 are to be returned to the University’s Utility Budget, and that 60% of the funds be dedicated to future ECMs. Th is submittal was approved by the State Energy Offi ce; however, due to macro-economic pressures within the NC Offi ce of Budget and Management (OSBM), no funds were allocated back to NC State this year.A summary of avoided and newly incurred costs related with energy

PEAK SHAVING MANAGES ENERGY USE ANDREDUCES ENERGY COSTS

Peak shaving is NC State’s demand-side management solution that reduces energy costs by lowering electric energy consumption during the peak time of the day, when rates are the highest. Th e University is implementing a Peak Shaving Initiative Program to reduce peak demand of electrical use during Progress Energy Carolinas, Inc. (PEC) on-peak hours. Th e peak shaving initiative is typically conducted from October through April. NC State can avoid as much as $20K-$75K per month by decreasing the peak demand during the warmest days of the billing cycle.

On the day of a peak-shaving event, building operators turn off unnecessary lights in all campus buildings and initiate the load shedding command from the Enterprise Level Control System (ELCS). Th is process raises the discharge air temperature setpoints for the HVAC units that are part of the program, thereby reducing energy consumption. Th e campus lab-user community is notifi ed to minimize energy consumption by keeping all non-essential fume hood sashes closed.

Th e district thermal plants also play an important role in peak shaving. For instance, the Yarbrough Steam Plant operators start the plant’s steam chiller (which does not use electricity) and turn off one of the 2,000-ton electric chillers. At the same time, the plant lets the chilled water temperature drift from 40°F to approximately 46°F. Th e peak shaving event is a coordinated eff ort between the building mechanical systems and the Central Utility Plants. Once peak shaving is completed, the plants and buildings return to normal operation. During FY 2010-11, the NC State saved more than $135,000 in electricity costs for the months October 2010 through April 2011.

Buildings.Projects targeting facilities are listed below:• Energy Management performed the

Intersession Setback Program, as it has done since FY 2004-05. Th is year the Th anksgiving holiday (November 25 to November 28) and the week prior to the holiday (December 17 to December 23) were included for the fi rst time in the setback program. In partnership with Building Maintenance and Operations (BM&O), nearly $190,000 in energy costs were avoided, and since its inception, the program has saved $1.2 million.

• Energy Management received an American Recovery and Reinvestment Act (ARRA) grant from the State Energy Offi ce to perform lighting upgrades across campus. Th e goal is to replace at least 17,000 T-12 lamps with energy effi cient T-8 lamps and 8,500 magnetic ballasts with electronic ballasts. Th is fi scal year, 4 buildings have been completed, and 132,548 kWh of energy has been saved, and a 156 kW peak reduction has been achieved.

• In May 2011 construction was completed on the Sullivan Shops III building, which when certifi ed by the US Green Building Council (USGBC), will be the fi rst Leadership in Energy and Environmental Design (LEED) certifi ed building on campus. It is expected to achieve LEED Silver certifi cation. Th e building is constructed from 75% recycled materials; it has 8 solar thermal collectors on the roof to assist with heating, and a rainwater collection system, which is used to fl ush toilets and for campus irrigation.

• NC State recognizes the importance of using solar energy to displace the use of natural gas wherever practical.

programs, contracts, agreements, tariff s, and rates are noted below:• Th e process of using transport

natural gas at NC State avoided expenditures of $471,241 in FY 2010-11 and more than $3 million since the program started in FY 2002-03. Unfortunately, the 70% increase in basis (marketing fee) cost presented by the natural gas marketer resulted in additional FY 2010-11 cost of $189,890.

• In FY 2010-11, the cost of fuel oil per British Th ermal Unit (BTU) was nearly 3 times more costly than natural gas. Additionally, fuel oil is corrosive to the interior of the boilers; therefore, it is not desirable

to burn fuel oil, except during natural gas curtailments. Public Service of North Carolina (PSNC) realized distribution problems in December and January and it was necessary to temporarily switch certain interruptible accounts to fuel oil supply. Th e burning of oil verses natural gas cost NC State an additional $850,000.

• Since FY 2002-03, several PEC electrical accounts were switched to Time of Use rate structures. Th ese,

and other accounts, are reviewed annually for their cost avoidance. In FY 2010-11, an avoided cost of $335,668 was realized and more than $1.4 million since the program was started to track savings.

• Water consumption data shows a 5% reduction in usage verses the FY 2009-10 and a 47% reduction compared to FY 2001-02.

• Th e 13-Building Performance Contract started in FY 2010-11 provided construction period energy savings of approximately $680,000. Th ese savings were not captured under the Reinvestment Legislation submission because the Performance Contract was executed before the law

was enacted.• Th e Reinvestment Legislation, or

GS143-64.12(a), was submitted with a total of more than $1.1 million in documented ECMs in FY 2010-11.

ENERGY USE IN FACILITIESIdentifying high energy use buildings enables Energy Management to plan energy projects. Th ese energy projects are intended to reduce energy consumption and help NC State meet, or exceed, standards set by Session Law 2007-546, Energy Conservation in State

ENERGY REINVESTMENT LEGISLATIONIn August 2011, the NC Legislature passed General Statute 143-64.12(a)

which mandates that for the UNC system schools, 100% of savings realized from Energy Conservation Measures (ECMs) be returned to the University’s utility budget. In addition, 75% of the savings are dedicated to fund future ECMs. North Carolina State University Facilities Division led the eff ort as the only UNC system school to submit a claim for Fiscal Year 2011. Th e results of the eff ort totalled more than $1.1 million in savings from ECMs in 2011. Unfortunately, due to budget constraints at the state level, the NC Offi ce of Budget and Management (OSBM) was not able to fund this claim.

Energy Management led the eff ort to compile this claim to OSBM, and in doing so, created the standard template for all future claims. Th is eff ort has not been in vain, all of the claims identifi ed in FY2010 can be claimed in subsequent years, as long as they continue to reduce energy costs.

During FY 2010-11, the installation of solar thermal systems to pre-heat domestic hot water and pool water at Carmichael Gym was completed.

EQUIPMENT EFFICIENCIESPursuant to the North Carolina Executive Order 156 that encourages all state agencies to maximize their eff orts to develop and implement environmentally sustainable policies and practices to minimize their impact on the environment and reduce their overall utility operating cost. Th e University has completed several projects to meet their commitment to reduce its GHG emissions. Th e following are snapshots of projects that are complete or will be completed in the near future:• Th e performance contract of 13

buildings with Schneider Electric is complete. Th e project will save the University $1.7 million annually.

• Th e next performance contract awarded to Amersco will install 2 - 5.5 combined heat and power (CHP) gas turbine generators at the Cates District Steam Plant. Th is project will save the University $1.7 million.

• Th e ARRA project consists of 3 projects that include lighting upgrades, retro-commissioning of the Varsity Research Building, and the replacement of 2 - 20-year old chillers. Th e ARRA projects are expected to reduce the University’s energy consuption by approximately 11,655 MMBtu annually.

• Th e University’s fume hood modernization converted 103 fume hoods at Dabney Hall from constant air volume (CAV) units to variable air volume (VAV) units as part of the 13 buildings performance contract. CAV uses on average 1,000 cubic feet

per minute (CFM) continuously, whereas VAV uses, on average, 1,000 CFM when in use, and 100 CFM when not in use. Th is is a 90% reduction in energy usage when the unit is idle.

CAMPUS INTEGRATIONOutreach eff orts throughout FY 2010-11 primarily focused on changing the campus culture with regard to energy and sustainability. Energy Management

ENERGY FELLOWSHIPS ON CAMPUSIn the fall of 2010, NC State Energy

Management was awarded a grant to fund 10 positions to train future energy professionals. Th e funding was secured through the NC State Energy Management, the DOE, and the ARRA, and supports the project until April 2012.

Th e 10 Fellows are split into pairs, each team working with 1 of 5 campus-related sponsor organizations: Energy Management, University Sustainability Offi ce, NC Solar Center, FREEDM Systems Center, and Advanced Energy. Together, the Fellows are working on 3 large-scale group projects to be completed by April 2012. Th e projects were chosen through discussion among the 5 partner groups and all will have a signifi cant impact on NC State’s campus energy consumption, research, and outreach long aft er the projects are completed. Th e projects are outlined below:

SMART GRID FEASIBILITY STUDY

Th e Centennial Campus Smart Grid Feasibility Study will evaluate the construction of a scalable, real-world smart grid project that shows the needs and benefi ts of smart grid technologies to universities, communities, and utility companies. Th is project will develop the smart grid energy management system from concept to reality by considering advantages and challenges that arise with deployment of smart grid on a larger scale.

EFFECTIVE SUSTAINABILITY OUTREACH MATERIALS

Th is group will develop sustainability and energy-effi ciency outreach materials that can be shared among all of the sponsor organizations. Deliverables will include paper media as well as audio and video outreach materials that can be used during public events. Th e outreach materials will accentuate the collaborative eff orts among all of the sponsors.

STATEWIDE CLEAN TRANSPORTATION PLAN

A coordinated plan is needed to expand and document the use of alternative fuel and advanced transportation in North Carolina. Th e plan includes establishing a common platform to track and report current alternative fuel use across North Carolina and coordinating an electric transportation roadmap component to facilitate the upcoming regional electric vehicle roll-out. Th e 3 local Clean Cities Coalitions are required to report annually to the DOE on alternative fuel activities in their regions, but no standard tracking exists to integrate activities outside of a designated coalition region. Th ere is also a need to coordinate electric vehicle infrastructure planning with the 3 Clean Cities Coalitions, Advanced Energy, NC Solar Center, ATEC, Duke Energy and PEC. Individual regional activities will benefi t from a coordinated eff ort to share resources and support a statewide roadmap.

16

and the University Sustainability Offi ce collaborate on ideas and initiatives geared toward campus energy use and conservation behavior. Activities include:• A newly redesigned website,

Sustainability at NC State, that showcases the joint accomplishments and initiatives of all campus sustainability-minded stakeholders.

• Th e Change Your State energy campaign has achieved new heights by promoting a 5% decrease in campus energy usage by the end of FY 2011-12. As part of Change Your State, interactive 360° photos of a lab, an offi ce, and residence hall spaces were simulated and displayed on the website to showcase how individual energy usage contributes to NC State’s overall energy consumption. Th is program helps reinforce the importance of conserving energy and water on campus.

• Shut the Sash, a laboratory energy conservation program, was implemented. Initial surveys of sash levels on fume hoods created a snap-shot of campus lab user behavior. Th e program was designed to promote proper lab fume hood best practices that reduce GHG emissions, and energy consumption.

• Energy Management, Waste Reduction and Recycling, and the University Sustainability Offi ce created energy metrics to promote sustainability and energy savings on campus. Th ese metrics were added to the Sustainability at NC State website as a scrolling toolbar that are advertised in the student newspaper, Th e Technician.

• Working with University Housing, 3 residence halls, Carroll, Sullivan, and Tucker were awarded Energy Star™ building certifi cation. Th ese

buildings perform in the top 25% compared to similar buildings.

• As part of the Energy Fellowship Program, the Outreach Materials team project has been charged with creating content that highlights the common eff orts of the partner organizations through the creation of new outreach materials.

SOLAR SYSTEMS ON TWO CAMPUSESSolar Photovoltaic System: Th e 40 kW rooft op solar system at the Keystone

Science Building on Centennial Campus took three weeks to install, and is forecasted to generate around 52,000 kWh of energy for the building annually. Th e entire solar system consists of 186 photovoltaic (PV) modules and four solar inverters. Th e solar inverters transition the direct current (DC) to alternating current (AC) for immediate use throughout the building and for specifi c research projects. In addition, the installation incorporates a monitoring system to feed real-time energy generation data to the FREEDM Systems Center engineers within the building.

With energy conservation and other green practices emerging as a critical part of day-to-day operations, it is essential that the University identify renewable sources of energy, and develop eff ective strategies for deployment and integration into the existing campus energy grid. Solar sources are ideal since the technology is considered safe, the solar access in North Carolina is very good, and the effi ciency of solar systems is constantly improving. Future large-scale deployment of solar energy and distributed energy generation within the campus energy grid will reduce the overall cost of operating the University, while making us less dependent on fossil fuels, and reducing our carbon footprint.

Solar Th ermal System: A solar thermal system was installed on the roof of Carmichael Gymnasium as a part of the 13-Building Energy Performance Contract project. Southern Energy Management of Morrisville installed the solar thermal project. It features 112 solar thermal panels, each measuring 10 feet by 4 feet. Th e system pre-heats the potable water for showers and locker room use, as well as assists heating water in the competition swimming pools.

Cold water is pumped up to the roof where it cycles through the installed solar panels. Solar energy warms the water and circulates it to the boiler room. In the boiler room, the solar-heated water goes through a heat exchanger to pre-heat the boiler water.

Th e system heating the pool works largely in the same way: pool water is pumped to the roof where it is warmed by the sun. Th e warm water is delivered to the pool equipment room where it supplements the pools heating system. Th e solar thermal system heats water to about 100 degrees as it is circulated onto the roof and piped through the solar equipment. In the pools, the water temperature is regulated at about 80 degrees. Th e system circulates about 70 gallons of water a minute, or 100,800 gallons a day, and takes more than a week to circulate all the water in both pools.

their partnership, energy savings for even the smallest projects will be documented and quantifi ed.Capital Project Management engages large projects (>$2,000,000) which typically take months in planning and design. Energy Management is tracking the planning process to identify upcoming large projects, and to enable the team to survey existing buildings’ energy consumption prior to demolition. Th rough this coordination, the “existing conditions” energy

survey can be taken into account and compared to the post-construction energy consumption.Design and Construction Services manages small projects that have projected construction costs of less than $2 million. Energy Management believes that the greatest opportunity to capture energy savings lies within these projects that have gone undocumented in the past. Th ese projects are initialized by the Offi ce of the University Architect, through the Facility Modifi cation (Fac Mod) process. Energy Management received a copy of each of the approved Fac Mods, and evaluated each one for potential inclusion in the claim for FY 2011-12.Th e Facilities Operations Budget Offi ce has an established relationship with the NC Offi ce of Budget and Management (OSBM) and compiles all

NORTH CAROLINA REINVESTMENT LEGISLATIONBACKGROUNDTh e UNC system schools all receive funding from the NC General Assembly to pay for utilities (natural gas, fuel oil, and electricity) on their respective campuses. Th e funds for each year are determined based upon a formula which considers need, projected utility costs, and most importantly, the prior year’s energy consumption.Each year, a proposal is submitted by NC State to the NC Legislature. Based upon their considerations and available State funds, a utility budget for the following fi scal year is allocated to the University.In the past, it was in a schools’ best interest to utilize most, if not all of the current year’s utility allocation, since a surplus indicates that too much money was budgeted for the previous year. If a surplus of funding occurred, the utility budget would be decreased for the next fi scal year.Beginning in FY 2010-11, the State Legislature passed Session Law 2010-196 revising General Statutes stating that:“...energy savings realized from implementing an energy conservation measure shall be carried forward by the institution to the next fi scal year. Sixty percent (60%) of the energy savings realized shall be utilized for energy conservation measures by that institution.”Th e documented ECMs are required to show realized savings, the verifi cation methods, the associated cost of implementation, and a simple payback value.Th e documentation must be submitted through SEO, who in turn review and verify the claim for the Legislature.In FY 2010-11, NC State University was the only UNC system school to submit a claim under this new

legislation. With assistance from other business units, Energy Management compiled the claim, identifying 40 ECMs totalling more than $1.1 million in energy savings during the course of the fi scal year. In addition, more than $680,000 was documented but unable to claim because the savings were from receipts-based groups within the University or were construction-period savings from the 13-Building Performance Contract. For future claims, the construction-period performance contract savings can be

included, but the current contract pre-dated the legislation, thereby excluding it from the claim.NC State has also led the eff ort to organize future claims for all of the UNC system schools. Energy Management created a template for each ECM so that SEO can better organize all of the claims they receive in the future. NC State’s template (Figure 6) has become the de facto template for all system schools.

CAMPUS PARTNERSHIPSEnergy Management understands that partnerships among the campus community units are required to be able to accurately document each ECM and quantify energy savings for all of them, large and small. BM&O typically replaces equipment upon failure, and until now, has not documented the energy consumption of the equipment being replaced. With

“energy savings realized from implementing an energy conservation measure shall be carried forward by the institution to the next fi scal year. Sixty percent (60%) of the energy savings realized shall be utilized for energy conservation measures by that institution.”

19

of the fi nancial data to formally submit the Utility Budget request. With their support, Energy Management is able to focus on the energy component of the claim, and allow the legislative logistics to be managed by others. Th eir partnership will become more critical in upcoming years, when the schedule and structure for submitting a claim is much more rigid.Th e existence of these campus partnerships enabled Energy Management to compile the Reinvestment Legislation claim for FY 2010-11. Without this team eff ort, Energy Management would not have been able to identify and quantify all of the projects listed in this year’s claim.

RESULTS OF THE CLAIMTh e claim submitted by NC State, and certifi ed by SEO, was accepted by the NC Offi ce of Budget and Management (OSBM) in June of 2011. Facilities Operations expected an energy reinvestment claim of $1,111,824 to be identifi ed in the FY 2011-12 utility budget. Unfortunately, all of the state budgets were cut, and OSBM was unable to fund the claim due to macro-economic conditions.

LOOKING AHEAD TO 2012With a strong infrastructure in place, Energy Management is looking forward to another signifi cant claim for energy reinvestment for FY 2011-12. All of the ECM projects identifi ed in FY 2010-11 will still be in service, and can be submitted again, and the planning that has occurred to track new ECMs will enable NC State Energy Management to lead the UNC systems schools with its Reinvestment Legislation Claim in FY 2011-12.

Summary of Work:

Each year since 2005, Energy Management has coordinated a program with BM&O to safely lower building temperatures during the Winter Holiday, when the University is closed. By lowering building temperature setpoints, NC State can save natural gas (NG) and electricity, thereby avoiding utility costs. Campus research labs and occupied support spaces are excluded from this program, and an process is in place for the campus community to request exemption from the program.

Energy consumption is measured in two ways: 1) electric consumption is tracked at the Progress Energy Substation and is compared to the baseline year to determine avoided kWh consumption; 2) natural gas consumption is metered at the Central Utility Plants and compared to the baseline year to determine avoided therms consumed.

In addition to the setbacks implemented by BM&O, the campus community was instructed to shut down non-essential lab equipment, to close fume hoods, to shut windows and doors, and to turn off lights and office equipment.

The Winter Holiday Setback period (12/24/2010 to 1/2/2011) avoided utility costs of $166,271, normalizing the savings by the campus gross square footage.

This is a zero-cost ECM, so the simple payback for the Energy Savings Initiative is 0.0 years. Refer to the attached report for additional data.

THE STRATEGIC ENERGY MANAGEMENT PLANINTRODUCTIONTh e NC State Strategic Energy Management Plan includes 41 individual components that together constitute a comprehensive energy management program. For FY 2011-12, Energy Management will focus eff orts on 3 areas that will address 12 components of the Strategic Energy Management Plan. A brief summary of each initiative follows:

ECM PROJECT DEVELOPMENTWith the hiring of an Energy Manager and 2 Energy Analysts for the period June 2011 to March 2012, NC State has an opportunity to quantify ECMs in campus-appropriated buildings. Energy audits will help build a project portfolio with building specifi c ECMs that include ROI metrics. As funding becomes available, ECMs will be properly scoped and estimated, thereby streamlining project selection. Reporting and tracking reinvestment legislation for utility savings will be included in the audits.Description:A fundamental component of Energy Management is the building energy audit. Th e energy audit examines the way energy is currently used and identifi es alternatives for reducing energy cost. Th e goals of the energy audit are listed below:• To clearly identify the types and costs

of energy use,• To understand how energy is being

used, and possibly wasted,• To identify and analyze alternatives

such as improved operational techniques and/or new equipment that could sustainably reduce energy costs, and

• To perform an economic analysis on those alternatives and determine which ones are cost-eff ective.

Business Case:Th e primary objective of energy

management is to minimize cost through judicious and eff ective use of energy. Th e energy audit identifi es and quantifi es opportunities to save cost. By developing a broad portfolio of ECMs by building, projects can be executed based on ROI, thereby maximizing the use of limited resources.Primary Task Breakdown:• Form the Energy Audit Team• Identify buildings to be audited

based on energy use intensity metrics• Establish the energy audit reporting

structure and schedule• Compile and review data, building

assessment reports, AERES reports, etc.

• Perform fi eld audit activities in a safe manner

• Develop concise reports by building and log fi ndings in an energy conservation database

• Write an Energy Action Plan that incorporates reinvestment funding drivers

Interaction Required:• Energy Management ARRA Building

Audit Team and Staff • Building Liaisons• BM&O• R&RCAMPUS CONTROLS UPDATEIn February 2006, consulting engineer Kling developed a bound report entitled A System of Connections: Campus Wide Controls Upgrade, SCADA and Metering Master Plan for the NC State Campus. Since then, many of the recommendations have been initiated; however, there have been changes in organization and technology. A fresh look at the 2006 Plan is required to validate and update the Plan.Description: Th e 2006 Plan evaluated the status of systems, identifi ed upgrade options, prioritized tasks and proposed an implementation schedule. Since then,

NC State has made strides with the roll out of the ELCS Tridium® Niagara AX® Platform and has installed the fi rst phase of a SCADA system at Sullivan Substation. Th e convergence of ELCS and SCADA, through a unifi ed graphic user interface, will enable facility and energy managers to operate the campus in the most effi cient manner possible.A blended team from Energy Management, Power Systems, and BM&O will review the 2006 Campus Automation Master Plan, validate and/or modify the technological recommendations, and issue an updated plan by May 2012.Business Case:Campus automation’s main purpose is to provide the University’s facility and energy managers with increased control that include the following benefi ts:• Develop a manageable building

alarm notifi cation and response system,

• Create a marriage of building system functions to utility plant functions,

• Peak demand limiting, and• Load shaving strategies.Together, these 4 command and control strategies have the potential to save the University millions of dollars.Primary Task Breakdown:• Identify team members and select a

facilitator• Review the 2006 Campus

Automation Master Plan• Update the plan to identify work

completed, validate conceptual framework, and KPIs

• Integrate the fi ndings and recommendations of the utility meter long range plan

• Review and make recommendations for a central plant unitary device monitoring plan

• Develop an ELCS/SCADA Control Room, including design level layouts

• Determine best procurement

strategies if the plan is implementedInteraction Required:• Energy Management• Power Systems• BM&O • Controls ConsultantFUEL PROCUREMENTIn fall 2012, the Cates Avenue Steam Plant natural gas and fuel oil fi red CHP combustion turbines will go on-line to supply the University with electricity and steam. Cost-eff ective procurement of natural gas and fuel oil will become of paramount importance to the University. Energy Management will go to the open marketplace to secure the lowest possible pricing to ensure the success of the Cates Avenue Steam Plant capital project.Description: NC State has 2 purchase methods to acquire natural gas. One method is

through PSNC Energy, also referred to as the local utility distribution company (LDC). A second method is with a commodities transport marketer, which is available for large accounts using more than 120,000 therms. In FY 2009-10, NC State used the transport marketer Texican for large accounts. Th e savings, or avoided cost, of using the marketer instead of the LDC has been greater than $2.7 million since FY 2001-02. In addition to natural gas, fuel oil is used during periods of natural gas curtailment. By leveraging seasonal spot market procurement methods, NC State can acquire fuel oil at the lowest price per gallon. Since FY 2001-02, these methods have saved over $2.4 million.Th e large natural gas accounts are currently being purchased under the terms stipulated in the North Carolina 405N Statewide Term Contract. Th is has worked well; however, NC State

anticipates installation of additional fuel burning equipment which will further increase the natural gas usage. Furthermore, in February 2011, unexpected rate changes resulted in higher natural gas costs. With the Cates Avenue Steam Plant renovations scheduled to come on line in fall 2012, NC State must review all options available to procure natural gas and fuel oil at the lowest possible price. Business Case:Based on data from SEO for FY 2009-10, NC State is the largest user of natural gas and, more importantly, has the lowest natural gas costs of all North Carolina public institutions, including all UNC system schools. Th is is confi rmation that current natural gas procurement methods are eff ective, but the University must do better. Implementing a professional energy procurement program will help ensure lowest market cost and achieve budget certainty.Primary Task Breakdown:• Solicit bids and select a qualifi ed

energy risk management consultant to design a natural gas and fuel oil procurement program

• Review existing energy contracts and engage Division of Purchasing and Contracts to ensure compliance with state requirements

• Develop a seasonal procurement strategy based on utility budgets, then issue RFPs to qualifi ed energy suppliers to meet demand

• Develop metric-based reporting and tracking reporting tools

TRACKING CAMPUS UTILITY CONSUMPTION AND DISTRIBUTIONEnergy Management currently tracks utilities delivered to most buildings on campus including several research facilities. Th e Unit reports on utilities from vendors such as PEC and PSNC Energy as well as utilities provided to individual campus facilities from substations and district thermal plants.Since baseline FY 2002-03, purchased utility consumption and utility costs have trended together, peaking in FY

2008-09, and have steadily declined since that time. Th is correlates with the timing of the establishment of a more pro-active Energy Management unit within Facilities Operations.While the legislative mandate of 30% energy reduction by FY 2014-15 is still a goal, it is a goal within reach. With the support of the campus community, it will be achieved.

Utility Account Demographics:• Purchased Utility Accounts (474):

~ 136 Electric ~ 101 Natural Gas ~ 137 Domestic Water/Irrigation

• NC State Utility Meters (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 soft ware monthly. Historical information is tracked through the Oracle database implemented for the EBS system. Th e NC State meters are used primarily to monitor consumption by receipt-funded entities. Energy Management also uses this information to benchmark utility consumption for diff erent building types (i.e., classroom, offi ce, and laboratory) where metering information is available. Th e report data is based primarily from supply-side, or purchased utilities, by NC State. Data from sub-metering on the demand-side is presented when available.

FACILITY ENERGY AND WATER CONSUMPTIONNC State aggressively manages strategies to minimize energy and water consumption. As a result, the University used approximately 4% less electrical and natural gas energy when normalized for campus growth compared to FY 2009-10. Th e organization accomplished this in the face of ongoing construction and extreme weather conditions. Specifi cally, the University increased 6% in total GSF and experienced a 3% increase in DD compared to FY 2009-10.When each of the utility types is reviewed individually (Figure 9, below), it is clear to see that both electric demand and natural gas consumption have been trending downward since FY 2008-09. Th is trend indicates the eff ectiveness of the Energy Management program instituted at NC State since 2009, as well as the expanded metering, monitoring, and reporting eff orts of the unit.

KEY PERFORMANCE INDICATORS

ANNUAL REPORT UTILITY DATAEach 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 continued to report 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. Figure 5, at right, visualizes the growth of campus, averaging 5%-6% per year, overlaid with the total utility cost

which has remained constant since FY 2007-08. Th is data also accounts for increases in the utility rates, which steadily increase over time. Extrapolating the data (see Figure 10), it is possible to expect that without the combined eff orts of NC State Facilities Operations over the past several years, the University’s annual utility costs would be approximately $39 million per year.

ENERGY AND WATER CONSUMPTION METRICSIn FY 2010-11, NC State realized the benefi ts of a multi-pronged eff ort to reduce energy consumption across campus. Th rough a combined eff ort from Facilities Division, led by Energy Management, the Energy Use per GSF dropped 5%, and continued the trend toward the goal of 30% total energy reduction by FY 2014-15. While the energy goal will continue to require signifi cant combined committments from the entire campus community, the goal is within sight.Successful water conservation programs continue to show progress, with a reduction of more than 5%. While the University has met the goal of 20% reduction in water consumption, a stretch goal of 50% reduction is in eff ect. Currently, NC State has reduced water consumption 47% compared to the baseline year of FY 2001-02.

CAMPUS COMPARISONS New trends using data from the campus community were developed in FY 2009-10, and have been projected back to include previous years’ data (Figure 13). Th e number of academic degrees conferred correlates to campus population and activity, and shows that energy consumption per academic degree has consistently dropped since FY 2007-08.Based on the data, the University is operating at 299 MBTUs per academic degree which compares to FY 2005-06 levels.

WEATHER NORMALIZATIONAnother factor Energy Management has applied to normalize energy is to consider changes in the campus square footage and weather over time. Figure 14 highlights the eff ort of the campus community to reduce total energy usage. As the data shows, the University has achieved a total energy use of 30 BTU/GSF/DD. Th is metric shows campus energy consumption at a level approximately 10% lower than the baseline year (FY 2002-03) and continuing a downward trend of more than 17% over the past 3 years.

TRENDS IN ENERGY AND WATER COSTSENERGY AND WATER COST METRICSOverall utility costs decreased from FY 2010-11. Even though utility rates are ever-rising, and the campus continues to grow at a rate of 6% per year, the eff orts of Energy Management have achieved an overall reduction in energy cost per GSF (see Figure 15).

AVOIDED COSTS: RATE NEGOTIATIONSANNUAL POLICIES FOR ENERGY SUPPLY MANAGEMENTEnergy Management monitors natural gas prices during each month for an opportunity to purchase cost-eff ective strips (bulk purchases) of natural gas which provide for budget certainty and cushion against price spikes resulting from extreme weather events. Unusually cold weather during December and January resulted in natural gas curtailments, and NC State needed to switch to fuel oil on certain

interruptible accounts at the CUPs. Final FY 2010-11 evaluations show the purchase of transport and strip natural gas, versus tariff natural gas resulted in overall savings of $471,241. Th ese savings, combined with a savings of more than $3,204,282 since the inception of the program, support the continuation of this procurement strategy.

Th e cost eff ectiveness of rate schedules for electric accounts was evaluated. Energy Management worked with PEC to record the savings from using TOU rates verses LGS rates. Th is evaluation informed the decision to switch additional qualifying accounts to the TOU rate. In FY 2010-11 alone more than $335,000 was saved, and the total avoided costs for the program since FY 2001-02 is more than $1.4 million.

LOOKING AHEAD TO FISCAL YEAR 2012PROJECTIONS FOR 2012Th e sustainability strategic plan, encompassing the CAP and Strategic Energy Management Plan are the roadmap that will ensure continued progress toward the 2015 goals for energy and water consumption. Progress over the past 3 fi scal years has laid the foundation for success in FY 2011-12, and continued energy reduction through the 2015 goals, and into the foreseeable future.

DATA MANAGEMENTData management encompasses the entire eff ort 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, Dr. H. James Harrington,

Measurement is the fi rst 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.Data management aligns with the University goals of effi cient management of resources while mitigating the related costs. Th is focus area is divided into 8 key sections as described below:• Use KPIs to provide a long range

plan based on modeling energy consumption and then frame actionable items accordingly.

• Set goals to prioritize energy reduction and carbon abatement strategies to further the University’s mission.

• Leverage Energy Star™ as an analysis tool to evaluate buildings against normalized models.

• Expand monitoring and control capabilities to enable a system-wide view.

• Develop an energy dashboard to enable the campus community to track energy reduction and carbon abatement.

• Set metering standards to provide real-time monitoring.

• Develop trend reporting capabilities.• Publish periodic energy and water

consumption reports.

SUPPLY MANAGEMENT NC State uses natural gas, fuel oil, and electricity to heat and cool buildings.Natural gas and electricity are the primary purchased energy sources. Following is a look-ahead to NC State’s Energy Supply Management considerations and programs that will be addressed during FY 2011-12.• An 11-megawatt natural gas

combustion cogeneration facility will be installed in fall 2011.

• PEC Electricity Rates are expected to rise by 4% and the City of Raleigh expects to increase water and sewer rates by 20%.

• An energy consultant will be contracted to review electric rates and tariff s, to ensure utilities are supplied at the lowest cost.

ENERGY USE IN FACILITIESEnergy Management continues to make strides to ensure that buildings are operated and maintained in a manner that ensures the highest possible effi ciency.• A standard is in place that mandates

that all new buildings and additions over 20,000 GSF be designed and built to LEEDTM Silver standards.

• Four new campus buildings are in the process of becoming LEEDTM

certifi ed: Sullivan Shops III, Randal B. Terry, Jr. Companion Animal Veterinary Medical Center, Th e Student Health Center addition, and the Eastern 4H Environmental Education and Conference Center.

• Six new projects in design and construction will seek minimum LEEDTM Silver certifi cation: Th e Point (Chancellor’s Residence), James B. Hunt, Jr. Library, Gregg Museum of Art and Design, Centennial Campus Student Housing, Greek Village Townhomes, and the Talley Student Center.

• Th e 13-Building Performance Contract will be completed during

ANOTHER LOOK AT BUILDINGS HELPS SAVE ENERGYRetro-commissioning (RCx) evaluates and adjusts existing buildings’ HVAC

systems to make them perform the way they are currently being used, not necessarily how they were originally designed. It identifi es operational and maintenance improvements in buildings and ensures that each mechanical system, alone and collectively, achieves optimal performance. Th e RCx process is an essential tool for optimizing energy performance and minimizing operational and maintenance cost. It evaluates each building system and the building as whole to maximize operation through peak performance algorithms. RCx helps the University comply with our mandate for the reduction of energy consumption. As part of RCx, poorly performing buildings are identifi ed by BM&O and Energy Management, then outside commissioning consultants are contracted to perform the RCx projects. When the project is completed, energy consumption is tracked, and the improved effi ciencies assist the development of a new energy profi le based on the behavior of the building. A properly implemented RCx project will yield a payback of less than 3 years.

31

FY 2011-12 and NC State is already gearing up for another round of performance contracts. Several high-energy consuming buildings have been identifi ed as potential candidates for the next round.

• In late FY 2010-11, Energy Management engaged an Energy Manager and 2 Energy Analysts funded through an ARRA grant. Th e team is performing building energy audits across campus.

EQUIPMENT EFFICIENCIES Th e following programs and policies will be implemented:• Th e University is developing policies

to guide departments to invest in energy-effi cient equipment.

• Th e University is considering incentives for the campus community to replace old and ineffi cient equipment.

• Fume hoods consume large amounts of energy, and Energy Management has addressed this issue through a fume hood modernization program.

CAMPUS INTEGRATION Saving energy and reducing the University’s carbon footprint will require the buy-in of the entire

campus community. During FY 2011-12, in partnership with the University Sustainability Offi ce, Energy Management continues to promote campus integration through the following outreach programs:• Energy Management plans to create

new, eff ective outreach materials that are both sustainable and reach faculty and staff .

• Th e Certifi ed Wolfpack Green Labs Program is a planned recognition program designed to award research labs that institute and encourage sustainable practices.

• Th e Shut the Sash program created a new poster for fall 2011 program that were placed in Fox Labs, Dabney Hall, and Riddick Hall. Th e program is being integrated into the building automation systems to provide real-time monitoring of fume hoods in labs.

• Energy Management, in collaboration with the University Sustainability Offi ce and University Housing, is planning future energy competitions in residence halls on campus. Th e eff ectiveness of awareness tools will be tested during the competition.

• Th e Student Sustainability Attitude Survey will be administered during the fall 2011 semester to update fi ndings from previous year’s survey.

• Th e CEST Energy and Water working group is partnering with Energy Management to increase end-user participation.

PARTNERSHIPS TO CUT WASTE IN THE LABSAs a world-class research campus, NC State has many diff erent types of

laboratories across campus. In order to do the quality research, specialized equipment is needed. Th is equipment oft en uses a lot of energy causing the labs on campus to be “energy hogs.” Ultra-Low Freezers (UTL) (freezers that reach temperatures of -86° Celsius, -123° Fahrenheit) are one of the biggest energy users in labs, each unit use around 20 kWh or energy per day, this is as much energy as an average house uses in a day!

Because UTL freezers use so much energy, we need to track and manage their installation on campus. Energy Management is conducting a survey to determine how many UTLs there are on campus as well as their condition, age, and to ensure they are being utilized properly. When the survey is complete, Energy Management will determine the oldest and worst condition freezers and discuss how they may be replaced with energy effi cient ones. A rebate program for labs that replace or eliminate old ultra-low freezers with energy effi cient ones is being considered. Ultimately, the goal of this project is to work hand-in-hand with researchers to ensure they are able to accomplish their goals in tandem with those of the University, and to aff ect behavior change through energy awareness and education.

ENERGY DETECTIVES UNCOVER CLUES TO BIG ENERGY SAVINGS

In June 2011, a team consisting of an energy manager and 2 energy analysts was charged with identifying and reporting energy savings opportunities at NC State. Th e positions are funded through the ARRA through the UNC General Administration in Chapel Hill. To date, the team has found savings on Centennial Campus that add up to more than $390,000 with a simple payback of less than 1 year in most cases. Th e team will continue searching for opportunities across the University armed with temperature sensors, light meters, binoculars, and laptops to calculate all of the savings. Th e hunt continues through March 2012, when they will have completed more than 50 detailed energy audits, outlining savings through temperature setbacks, lighting upgrades, operational changes, building automation scheduling, and equipment utilization enhancements that will save the University 10% to 15% in energy consumption.
