Introduction Background Information Sample ISD elected to take advantage of the building energy performance benchmarking support provided on behalf of the Sample Program. This benchmarking study includes 24 schools, and the breakdown by school type is as follows: 14 Elementary Schools 4 Middle Schools 4 High Schools 2 Other Schools- Alternative The energy consumption data used in this benchmarking study covers July 2009-June 2010. The data was reviewed for quality and accuracy and facilities with questionable data were eliminated from the survey. Source: 2011 Google Energy Performance Benchmarking Provided by CLEAResult 3

The Purpose of Benchmarking Benchmarking the energy performance of your schools is the first step in determining where and how to implement energy improvements within your district. This Energy Benchmarking Report compares your schools energy performance against each other and against regional and national databases. This comparison will help you identify which of your schools have the greatest opportunities for energy and cost savings. This report: Introduces and provides an overview of the benchmarking process. Presents your district s overall energy performance as well as the performance of each school. Provides information about how to receive recognition for your energy efficiency efforts. The Benchmarking Process The energy and building data you provided e.g. twelve months of utility bills, school square footages, and number of students is entered into two separate energy performance rating systems. CLEAResult s Regional Energy Performance Databases and Data Modeling Process These databases contain building characteristics and energy usage information from hundreds of schools that CLEAResult has benchmarked in your climate region. These buildings provide a good basis for comparison of energy performance, as they experience similar outdoor temperature and humidity levels as your buildings. After uploading your information into the database for your region, a software model calculates the following energy benchmarks for each of your schools: annual energy use per square foot (Energy Use Index), annual energy cost per square foot (Energy Cost Index), and annual energy cost per student. The model then compares your calculated energy benchmarks to other schools in your climate region. The model only compares those schools of similar type and heat source (e.g. gas heated high schools are only compared to other gas heated high schools, etc). The U.S. Environmental Protection Agency s (EPA) ENERGY STAR Portfolio Manager Tool Portfolio Manager is an online benchmarking tool that uses a mathematical algorithm to rank energy performance on a scale of 1 to 100. The algorithm was created based on actual building and utility data from hundreds of K-12 schools surveyed nationwide in the Department of Energy s (DOE) Commercial Building Energy Consumption Survey (CBECS). Portfolio Manager incorporates both energy consumption data and building characteristics such as number of computers, the presence of cooking facilities, square footage, and location (for weather adjustments) into its calculations. Once this information is uploaded, Portfolio Manager assigns an energy performance rating to your school. A score of 50 indicates that your school is performing better than half of schools nationwide. Schools scoring 75 or better may be eligible to apply for the ENERGY STAR Label. Your schools characteristics, utility data, calculated energy benchmarks, and percentile rankings are presented in a number of ways throughout the following report and the Appendix.

Executive Summary This executive summary below is meant to provide a snapshot of your district s performance in this energy benchmarking analysis. The table to the left provides various metrics for your entire district as well as your rank against other local districts. This should help your district gauge where it stacks up in the local area, in both gross figures and those normalized for square footage. The boxes to the right compare your district s energy cost to the median in three ways: 1) across the entire district, 2) at those schools spending less per square foot than the median, 3) at those schools spending more per square foot than the median (savings potential). The pie chart shows your district s savings potential as a percentage of overall energy cost. The financing example illustrates the amount of project costs that could be financed via the savings potential. This chart focuses solely on cost savings available by bringing your schools in line with the median. There likely are many more opportunities across your district.

Energy Use Charts Correlation with Building Characteristics A common misconception about energy performance is that newer schools built under newer codes are relatively less energy intensive. Similarly, there is a misconception that high schools with their longer hours of operation and their use of gym spaces are considerably more energy intensive than K-8 schools. The graph below illustrates that newer schools use just as much if not more energy per square foot as older ones. Similarly, high schools only use slightly more energy per square foot than K-8 schools. The wide range of energy intensities indicates the magnitude of the effect that good energy managers and operating procedures can have on school energy consumption and costs. 100 Energy Use by School Type and Year Built in Texas High Schools Middle Schools Elementary Schools 90 Energy Use Index (kbtu/ Sq.Ft.) 80 70 60 50 40 30 HS MS ES 20 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Year Built Energy Performance Benchmarking Provided by CLEAResult 8

Comparison with Schools in Local Region Annual energy use per square foot, also known as Energy Use Index (EUI), is one of the most common ways to compare energy consumption between buildings. This parameter is all inclusive it incorporates the energy used for heating, cooling, dehumidifying, lights, cooking, computers, etc. and it also normalizes based on building size. The scatter plot below illustrates how your schools compare to the rest of the schools in our database in climate regions like yours.

Medians for Local Region The following chart shows the range of energy use (kbtu/sq.ft) for K-12 schools in your local area. The blue dash (which is labeled) represents the median for each school type and heat source. The orange dot illustrates where your schools within each particular category fall on the range (if applicable). Notice that gas-heated schools tend to consume more energy per square foot than those heated solely via electricity. As noted previously, secondary schools often consume slightly more energy per square foot than elementary schools. Energy Performance Benchmarking Provided by CLEAResult 10

Comparison with Medians The following chart shows the energy use (kbtu/sq.ft) for each of your K-12 schools. The red and blue bars signify the portions of overall energy use attributable to electricity & natural gas, respectively. The black line represents the median for the particular school type and heat source. Energy Performance Benchmarking Provided by CLEAResult 11

Targeting Schools for Further Assessment The following conceptual chart shows the energy savings opportunity for each of your K-12 schools. The size of each box indicates the respective square footage of each school, and the color represents its energy performance compared to the median. For example, a large dark red box points to a large school that is consuming significantly more energy per square foot than the median, which would make it an ideal school to target for further assessment. Bottom Performers Median Top Performers Energy Performance Benchmarking Provided by CLEAResult 13

Comparison with Local School Districts The bar graph below compares your school district s overall energy use (kbtu/sq.ft) to other districts in your immediate local area only. Your district s overall Energy Use Index (EUI) is highlighted in orange. Lower EUI bars indicate lower energy use / better performance. Energy Performance Benchmarking Provided by CLEAResult 14

Energy Costs Because the cost of energy fluctuates regularly, it is best to think in terms of energy use (normalized consumption per square foot). However, annual energy cost is another valuable way to decide where to focus your energy efficiency efforts. The chart below displays your district s annual energy cost by school. Each bar is color-coded to illustrate how each school is performing compared to others in your district in terms of normalized cost per square foot.

Energy Performance Benchmarking Analysis 1 CLEAResult Energy Benchmarks: Sample ISD Energy Benchmarking Report Energy Use Index (EUI) Also known as site energy, Energy Use Index is one of the most common ways to compare energy consumption between schools. This metric includes twelve months of utility consumption data in units of kbtu, divided by the total square footage of the school. Energy Cost Index (ECI) Potential to reduce energy costs is a prime motivator for investment in energy efficiency upgrades. This metric includes twelve months of utility costs, divided by the total square footage of the school. Energy Cost Index is a simple way to compare how much it costs to operate each of your schools. Energy Cost per Student Another excellent way to compare the cost of operations and maintenance at schools is by student. This metric includes twelve months of utility costs, divided by the number of students enrolled at the school. U.S. EPA ENERGY STAR Portfolio Manager Rating: Portfolio Manager Rating An online benchmarking tool that uses a mathematical algorithm to rank energy performance on a scale of 1 to 100, Portfolio Manager incorporates both energy consumption data and building characteristics such as number of computers, the presence of cooking facilities, square footage, and location (for weather adjustments) into its calculations. A score of 50 indicates that the school is performing better than half of K-12 schools nationwide. Schools scoring 75 or better may be eligible to apply for the ENERGY STAR Label. The Energy Performance Benchmarking Analysis chart on the following page is an aggregate summary of all the schools in your district. Charts for each individual school in the district are provided in alphabetical order in the Appendix. The top half of the chart consists of a scale for of the energy performance metrics described above. The upper left corner of the chart contains two columns of data. The first column is the median for each energy performance metric (for your particular climate region, school type, and heat source), and the second column is your school s calculated metric. The scales to the right illustrate where your school ranks compared to the median and other schools for each energy performance metric. The median for each performance metric is colored dark blue, and your school(s) is colored orange above the scale. The color-coded scale shows the range of values in our database for each particular energy performance metric. The scale moves from those schools performing well (green) to average (yellow) to poorly (red). Please notice where your school(s) falls on this continuum. The bottom half of the chart summarizes the building characteristics and energy use/cost data for your school(s). Please keep in mind that flawed input data leads to inaccurate results. 1 This report compares energy use based on utility bills and is not the result of an engineering assessment. The analysis is purely mathematical and is not meant to provide a subjective assessment of how schools are managed or operated. Most of the indicators do not adjust for individual building conditions (such as extended hours of building use, thermal storage systems, or swimming pools), and therefore should be used only as a tool in combination with knowledge of facility operations.

Energy Performance by School Type The following tables summarize the Energy Performance Benchmarking Analysis data for each of your schools. Both tables show four energy performance indicators for each school three calculated benchmarks (Energy Use Index, Energy Cost Index, Energy Cost per Student) and its EPA Portfolio Manager Rating. The table below shows these energy performance indicators grouped by school type, and then sorted from lowest to highest Energy Use Index. The schools listed toward the top of each group are performing better than those listed under them. Even if your school district performs well overall, below average schools can present a great opportunity for savings. Energy Performance Indicators Grouped by School Type Buildings are ranked by Energy Use Index within each school type. Energy Performance Benchmarking Provided by CLEAResult 18

Energy Performance by Quartiles In the following tables your schools are sorted into quartiles by energy use (kbtu/sq.ft) regardless of school type. The respective performance quartile of each energy performance indicator is indicated by the color of the adjacent circle. This is meant to help you prioritize schools for improvement projects. For example, a school with red dots across the board is performing in the last quartile with respect to each metric, and may be worth targeting for further assessment.

Translating the Numbers into Savings Sample ISD Energy Benchmarking Report Although benchmarking does not tell you what specific equipment or building features need to be improved, or how much it will cost to make the improvements, it can help you determine the general magnitude of the opportunities available and on which schools to focus. Comparing the energy performance of your schools is the first step toward improving performance and saving money. Energy efficiency equipment upgrades and operations improvements can have a dramatic financial impact on a school district. The table below illustrates how many budget dollars your school district would save under various savings target scenarios. Potential Energy Cost Savings by Energy Use Quartile Quartiles are represented in green, yellow, orange, and red. More detailed information about the school(s) should be gathered and analyzed in order to verify the magnitude of the opportunities and then move forward with improvement projects. Please refer to the previous page to see which schools belong to each energy use quartile. The table below presents your savings opportunity in a different way, showing how many budget dollars your district would save by reducing energy costs at your schools by 10, 20, or 30 percent. Potential Energy Cost Savings by Percentage Reduction The next step towards realizing these savings is to identify specific energy efficiency opportunities within your school district. Your Program Consultant can help you identify and evaluate energy efficiency opportunities and help you calculate the anticipated cost savings and cash incentives for each energy efficiency measure.

Greenhouse Gas Emissions 2 With scientific evidence connecting greenhouse gas (GHG) emissions from human activities to global climate change, many school districts are looking to find ways to reduce their carbon footprint. To document progress on this front, districts must first measure the current environmental impact of their schools. This benchmarking analysis accounts for GHG emissions produced by 12 months of electricity and heating fuel (natural gas) consumption. The following table shows your buildings greenhouse gas emissions from lowest to highest annual metric tons of carbon dioxide emitted per square foot. 2 The information in this section on greenhouses gases was derived in large part from Local Government Operations Protocol for the quantification and reporting of greenhouse gas emissions inventories. http://www.theclimateregistry.org/downloads/2009/05/lgo_protocol.pdf Energy Performance Benchmarking Provided by CLEAResult 23

Conduct incentive check presentations at Board meetings and issue press releases with stories and photos of the event. ENERGY STAR Label for Buildings America s desire for environmentally friendly buildings is growing, and superior energy efficiency identified by the ENERGY STAR is a critical element of a green building. Buildings achieving a rating of 75 or higher through EPA s online Portfolio Manager performance rating system are potentially eligible to apply for the ENERGY STAR Building Label. The application process requires that a Professional Engineer visit the building to ensure that energy data is correct and that lighting and ventilation levels are appropriate. ENERGY STAR Labeled buildings are the top performers for energy efficiency nationwide and use about 35 percent less energy than average buildings. Nearly 4,000 buildings in all 50 states have earned the prestigious ENERGY STAR. A number of Professional Engineers throughout the nation have volunteered to provide free ENERGY STAR label certifications for K-12 schools. Please click here to view the list of participating engineers in your area published on the ENERGY STAR website. ENERGY STAR Leaders EPA recognizes school districts and businesses as ENERGY STAR Leaders based on organization-wide, documented improvement in energy performance. To be eligible for recognition as an ENERGY STAR Leader, an organization must reduce its normalized energy use by 10%, 20%, 30% (or more), or achieve an average Portfolio Manager rating of 75 or better across their portfolio of buildings.
