Introduction

North Carolina State University, located in Raleigh, North Carolina, is a land grant University with approximately 35,000 students, faculty and staff. NCSU is a leader in the areas of teaching, research and public service. Facilities Operations through the Office of Energy Management has been charged with the responsibility to manage the energy and water resources purchased and consumed by NCSU in the most cost efficient manner and to promote energy and water conservation and awareness throughout the campus community. Our activities must support a superior academic environment and continued growth while simultaneously accomplishing our primary conservation responsibilities.

Our Mission

Our Staff

Our Vision

The Office of Energy Management recognizes that by being good stewards of our energy and water resources we will maintain a quality environment while reducing consumption and controlling costs. This will be accomplished by creating a culture that is dedicated to achieving environmental sustainability by supporting conservation objectives and recognizing and eliminating waste.

The vision of the Office of Energy Management is to sustain a long-term reduction of energy that is purchased by NCSU. We have established the goal of tracking and recording the Aggregate Annual Energy Consumption per Gross Square Foot, adjusted for weather. Additionally, we will reduce the Annual Water Consumption per Gross Square Foot over 2001-02. We will promote campus sustainability through the managed use of energy and water.

Fiscal year 2003-2004 was the inaugural year for the Office of Energy Management at NC State University. There are now seven full-time employees including an Energy Program Manager, Energy Management Engineer, Energy Data Analyst, three Electronic Technicians, and a dedicated Meter Reader.


Our Implementation StrategyEnergy management in a complex ever-changing environment is as much a journey as a destination. Growth, new technologies, environmental concerns, availability of fuels and new regulations and codes are a few of the challenges we must navigate. The Energy Management Plan is the roadmap we use to establish our objectives and guide our activities. A matrix, based on our Energy Management Plan, was created to track the progress of our activities (see page 32). The plan has five focus areas:

Energy Data ManagementEnergy Supply Management Energy and Water Use in FacilitiesEquipment EfficiencyCampus Integration

Each of these focus areas is being implemented in a five-step dynamic approach:

Information Gathering – The first step in the execution of any project or activity is to identify the sources of information available, gather that information, and present it in a meaningful and understandable form.

Plan – Based on the information gathered an action plan should be developed. This will include procedures for execution of the project, the goals for the project and the indicators that will be used to measure the success of the project.

Act – The actual execution of the plan.

Measure – Monitor and report on the key indicators as outlined in the plan.

Assess – Review and evaluate the findings and continue with the plan or revise as required.

Introduction

In August 2007, North Carolina General Assembly passed Session Law 2007-546 to make leading strides toward energy and water conservation. This law states that all current state buildings must be 20% more energy efficient by the year 2010, and 30% more efficient by the year 2015. It also states that all new state buildings will be 30% more energy efficient. All schools within the UNC School System and North Carolina Community College System must adhere to this law. It is also the intent of the General Assembly that priority be given to North Carolina-based resources to provide economic growth to North Carolina.


Accomplishments for 2008-2009

Energy Data Management HighlightsThe addition of sixteen• “state of the art” Nexus electrical meters this fiscal year, is providing real-time monitoring of electrical demand and continuous tracking of energy use. The Nexus metering also supplies advanced tools for evaluation of building loads, and contributing elements tied to building circuitry. As part of the ongoing mission, additional real-time metering is being added to the campus infrastructure whenever opportunites arise.

The implementation of Crystal Reports software •is streamlining the data gathering process by allowing access to data from the EBS billing software database and other sources. Previously, this data was difficult to obtain. This is resulting in better customer service by enabling quicker response times for unique data requests.

In an effort to better serve internal utility •customers, the web portal for the EBS billing software is in operational status. This allows internal customers to proactively track and better understand monthly consumption and billing. This further allows building and budget managers the opportunity to better control costs and forecast expenditures dealing with utilities. At present, there are thirty-three users for the EBS Web Portal with eleven users added since last year.

Energy Star was created in 1992 as a joint program between the U.S. Environmental Protection Agency and the U.S. Department of Energy. Over 70% of Americans recognize the Energy Star label. Over the past decade, ENERGY STAR has been a driving force behind the more widespread use of such technological innovations as efficient fluorescent lighting, power management systems for office equipment, and low standby energy use.

By becoming an Energy Star Partner, NC State University has committed to improving their energy usage campus-wide. This partnership provides technical resources and tools for energy solu-tions and better management of practices.

Energy Data Management Activities


Energy Supply Management Highlights

The purchase of tariff, transport and strip natural gas versus fuel oil was evaluated monthly. •Purchase of transport and strip natural gas was continued to take advantage of historical trends indicating potential cost-avoidance for the University.

The cost effectiveness of rate schedules for electric accounts was and continues to be monitored. •The savings of using Time of Use rates versus standard rates was tracked on thirty-eight accounts.

The demand profiles for the Sullivan sub-station were identified allowing the building automation •group to attempt to alter building settings on the load side to shift the supply side demand peak to a later time.

Fine-tuning the ability to shift loads to non-peak periods will allow a significant opportunity o for cost avoidance for the supply side rates.

Campus Integration Management HighlightsLabels were placed in strategic entrances and exits to campus buildings promoting “Just Switch •It OFF.” As new and renovated buildings came online, new labels were placed. Additionally, mousepads have been placed in available student computing lab locations.

Daily advertisements were run in the student newspaper, “the Technician.” These advertisements •often held tips and tricks to help students conserve water and energy in their normal daily routines. Additionally, large full-color advertisements were placed in special editions of the Technician, such as the Student Orientation Guide and the Fall Football Preview.

The Office of Energy Management facilitated the Conservation Action Team, and actively •participated in the Campus Environmental Sustainability Team (CEST). This involvement allowed for collaborative work with campus entities to increase education and organize efforts for overall campus sustainability.

The Million Dollar Challenge was promoted during New Student Orientations, Earth Day activities, •at residence halls, and during other events such as Energy Awareness Week.

Conservation awareness was highlighted on Earth Day with the introduction of the HPG, Human •Power Generator. The display helped participants better understand the physical energy required to power both incandescent and compact flourescent bulbs.

Charting Utilities 2008-2009

The Office of Energy Management is currently responsible for managing purchased utility for most buildings on main campus and several research facilities. It reports on utilities purchased from vendors (such as Progress Energy and PSNC Energy) as well as utilities provided to individual campus facilities (from substations and thermal plants):

Purchased Utility Accounts: 130 electric, 105 natural gas, 104 domestic water/irrigation•

Demand Utility Meters: 230 electric, 79 steam/condensate, 189 cold water, 30 domestic and heating •hot water, and 61 chilled water.

Total meters: 586•

The purchased utilities are paid through the PeopleSoft financial system using the EBS interface.

The demand utility meters are read each month with a hand-held device and entered into EBS, utility billing software system. Historical information on demand and purchased utilities is now tracked through the Oracle database implemented for the EBS system. Currently, the demand data is used primarily to monitor consumption by receipt-funded entities such as University Housing and University Dining. We are also using this information to benchmark utility consumption for different building types (ie. classroom, office, and laboratory) where metering information is available.

The data presented is based mainly from supply side, or “purchased utilities,” by NC State. Data from sub-metering on the demand side is presented when available.

Trends in Energy and Water ConsumptionThe energy use per square foot had experienced a steady decline until 2007-08 (see Figure 1). Overall, based on total million BTUs per square foot, energy usage per square foot has increased by 3.1% over baseline year, 2002-03. This energy use per square foot does not take into account the effect of weather on energy use.

North Carolina State University has committed to the State of North Carolina to reduce its energy consumption per gross square foot, adjusted for weather. This is measured in BTU per square foot per total heating and cooling degree days (BTU/ft2/DD). The trend of energy adjusted for weather has also began to increase as shown in Figure 2. Since 2002-03, North Carolina State University has increased by 9.4% in BTU/ft2/DD overall. FY 2008-09 brought some additional buildings online either through new construction or renovation. In either case, building controls were not optimized until these buildings were brought online and appropriately sealed. The energy demand increased as a result of this variety of conditions.

NC State University’s water consumption was reduced by over 29.4% from the 2001-02 baseline. Water conservation practices were implemented and expanded in response to the severe drought and have been maintained into the first part of 2008-09 . This is all due to improved irrigation control, operation of central chilled water plants, installation of water saving fixtures (ie. showers, faucets, laundry machines, etc.) and changes in awareness and behaviors.

Figure 2

Figure 3

Figure 1



Trends in Energy and Water Costs

There has been a significant decrease in fossil fuel prices this year due to the economic downturn. Although the natural gas prices has temporarily dropped, the electric rates have continued the upward climb. The cost of water has also increased. Therefore, while conservation measures are implemented to reduce the overall consumption, the cost per square foot will likely continue to increase. The cost per square foot is now about $2.66, which is a 1.6% decrease over 2007-08. This cost is up by 34.1% over baseline 2002-03.

A separate key performance indicator that NC State University is tracking is the cost per Fall Term Enrolled (FTE) student. The FTE reported only includes on-campus students (not distance education students). While the physical campus has been expanding rapidly due to the 2000 Bonds for Higher Education, there has not yet been a significant increase in student enrollment. The cost per student has increased 53.4% over baseline 2002-03 (see Figure 5).

Energy and Water Use Management Activities


In June 2008, in the wake of an extreme multi-year drought, the decision was made to install a rainwater collection tank in Yarbrough Drive Thermal Plant. The water collected in this 1,000 gallon tank is used for cooling tower make-up. Cooling towers require huge amounts of water in order to do their job, much of which is lost into the atmosphere as condensate. Instead of purchas-ing additional potable water, rainwater is collect-ed in this tank from the roof of the plant and then pumped back into the cooling towers. In the month since its installation, this system has collected and made up, and thus avoided the purchase of thou-sands of gallons of water.

The Million Dollar Challenge is a marketing campaign encouraging all campus populations to conserve. We

stress that a little saved by each of us can provide a level of savings that will help maintain or even reduce the

operating expense at NC State University. By each person on campus saving $.15 per day in energy and water

consumption, we have the potential to save over $1,000,000. For example, if a student keeps the light

off in their dorm room for 16 hours each day, they will save $.10. They can make up the remaining $.05 by

turning off the water when they brush their teeth and shave.
