    Certified ‘Green’ Schools

     North Carolina taxpayers are the winners when public schools operate efciently and when every

     public dollar is put to its best use and evaluated carefully. Ofcials and administrators who pursue

    these goals should be applauded for their commitment. But good intentions do not ensure benecial

    outcomes.

    Such is the story with “green” school buildings in North Carolina. This report analyzes “green” facilities

    in four school districts: Wake, Durham, and Buncombe counties, along with the Iredell-Statesville public

    schools. Research focused on schools receiving certication from the U.S. Green Building Council’s

    Leadership in Energy and Environment Design, or LEED, system.

    This report’s author concludes “green” school buildings in North Carolina fall far short of their promises

    to protect the environment through lower energy costs and increased efciency.

    •  None of the “green” schools are best-performing in energy use when compared to similar schools in

    the same district

    • In every school district, at least one of the “green” schools performs below average compared to

    similar schools in the same district

    • In many cases “green” schools require changes that end up increasing cost and reducing energy

    efciency

    • Buncombe County: Instead of using 30 percent less energy, the county’s two green schools used 7

     percent more energy than nongreen schools

    • Iredell-Statesville: Third Creek Elementary is billed as the rst LEED “Gold”- certied school building

    in the nation but spends about $7,775 more per year on energy than the district’s average elementary

    school

    • Durham County: Among 28 comparable schools, the two green schools rank No. 10 and No. 15 in

    energy efciency, with both schools performing signicantly worse than a much older district school

    that spends about 34 percent to 37 percent less on energy

    • Wake County: The district’s one “green” elementary school uses more natural gas per square foot than

    comparable elementary schools in the district

    • Policymakers seeking efciencies in school construction should analyze the lackluster results of their

    sister districts and invest public dollars only in methods and technology that produce savings and

     benets

    Introduction

    Charles T. Koontz and Joe. P. Eblen Intermediate

    Schools in the Buncombe County School District were

    designed as models of energy efciency.

    Built in 2011 and 2012, these schools received

    certication from the U.S. Green Building Council’s(USGBC) Leadership in Energy and Environment

    Design (LEED) system. Both are LEED Silver certied

    and were designed to use “30-35 percent less energy

    than a typical school.”1 

     Now that they are a few years old, do they meet that

    standard? The answer is “no.”

    Utility data from the 2014-15 school year show that,

    when compared to other middle schools in Buncombe

    County, the two schools rank below average for energy

    efciency, using more energy per square foot than most

    of the other schools. Both schools spent 77 cents per

    square foot for energy through May of 2015, compared

    to the average of 72 cents per square foot for the other

    eight middle schools in the district. Instead of using

    30 percent less energy, these green schools used seven

     percent more energy than non-green schools.

    These schools are not unique. Across North Carolina

    and the United States, so-called “green” buildings often

    use more energy than their non-green counterparts in

    the same school districts. For example:

    • In Spokane, Wash., none of the new green elementary

    schools are as energy efficient as the traditionally

     bu ilt Browne Elementary School . One of the

    allegedly green schools uses 30 percent more energy

    than Browne.

    • In Santa Fe, NM, the facilities director reports the

    district will not build another green-certied building

    anytime soon after the rst such building, Amy Biehl

    Community School, consistently incurred some of

    the highest energy costs in the district.2

    • USA Today found in 2012 that green schools perform

     poorly in Houston as well. The newspaper reported,

    “Thompson Elementary ranked 205th out of 239

    Houston schools in a report last year for the district that

    showed each school’s energy cost per student. [Green

    school] Walnut Bend Elementary ranked 155th.”3

    The situation is similar in North Carolina, where a

    number of schools intended to save energy actually use

    more energy per square foot than other schools.4

    Of course not every green school performs poorly

    Some green schools are more efficient than their

    counterparts in the same district. Even when that isthe case, however, green schools are usually more

    expensive to build and operate than traditionally buil

    schools, raising the question of whether they save

    money for the local school district.

    In many cases green schools require changes that end

    up increasing cost and reducing energy efciency. One

    facility director in North Carolina indicated that meeting

    LEED standards for one school would have required

    including a larger air conditioning unit to increase air

    circulation in the school. That larger unit would not onlyhave cost more; it would have used more energy. Such

    counterintuitive requirements are one reason LEED

    green schools do not live up to their promises.

    In this report we examine green schools in four North

    Carolina school districts – Buncombe County, Iredell-

    Statesville, Durham, and Wake County – to compare

    the energy performance of those schools to others in

    the same district. Schools provide a good opportunity

    to assess green building standards in general because

    schools are about the same size; have the same building

    elements; are located in the same climate; and there are

    a number of similar buildings nearby for comparison.5

    Do Green Schools Live up to Their Promises?

    Advocates claim that green schools produce many

    environmental benets. The USGBC denes a green

    school as “a school building or facility that creates

    a healthy environment that is conducive to learning

    while saving energy, resources and money.”6 Many

    of these points involve subjective judgments that are

    difcult to measure. Efforts to link the supposed health

     benets from green buildings and the learning progress

    Counterintuitive requirements are

    one reason LEED green schools do

    not live up to their promises.

    of students are vague and subject to many other

    inuences.7

    Energy use and energy costs, however, are useful

    and objective metrics that can be easily measured

    and compared. Since a reduction in energy use is

    at the center of what it means for a building to begreen, it is the most useful way to compare the actual

    environmental results of these schools to traditionally

     built schools. Additionally, we try to compare schools

     built recently. The question is not whether new green

    schools are superior to old, traditionally built schools.

    The important question is whether spending more for

    a new, green school will yield cost and energy savings

    compared to a new, traditionally built school. Stated

    another way: Does the energy use of green buildings

     justify their significantly higher construction and

    operating cost?

    Using this metric, the green schools in North Carolina

    that we studied fare poorly. Every school district that

    we studied in the state has at least one green school that

    uses more energy per square foot than a traditionally

     built school located in the same district.

    At a time when resources for education and for

     protecting the environment are scarce, state legislators

    and policymakers should look closely at green schools

    and question whether policies that promote or require

    those costly standards actually yield the promised benets.

    What are Green Buildings?

    Before examining the performance of green schools in

     North Carolina, it is important to know what the term

    means. Although denitions vary, the most common

    standard for green schools is the Leadership in Energy

    and Environmental Design (LEED) system created and

     promoted by the USGBC.

    To meet the LEED standard, building designers must

    achieve points in a number of categories. The LEED

    checklist for schools includes categories for:8

    • Sustainable Sites

    • Water Efciency

    • Energy and Atmosphere

    • Materials and Resources

    • Indoor Environmental Quality

    • Innovation and Design Process

    • Regional Priority Credits

    Points are awarded in each category and if a school

    design receives 40 out of a possible 110 points, it is

    certified as green. At 50 points a building achieves

    LEED Silver status; at 60, LEED Gold; and at 80 orabove, Platinum, the highest rating. Our study covers

    a variety of certication levels, including some at the

    lowest end of the scale, like Silver-rated W.G. Pearson

    Elementary School in Durham, as well as some meeting

    the LEED Gold standard, like Third Creek Elementary

    in the Iredell-Statesville School District.

    Some rating categories are specically designed to save

    energy, such as points for energy savings in a computer

    simulation of the building. Others are unrelated to

    energy, like the four points awarded for “PublicTransportation Access.”

    Advocates of LEED argue this system of flexibility

    allows schools to meet the standard at a relatively low

    cost. As districts move up the ladder of certication

    toward Platinum, the exibility is reduced and the cost

    can increase signicantly.

    As we shall see, even at the low end of the green

     building spectrum, the additional design, construction

    and operating costs more than outweigh the energy

    savings achieved by the buildings.

    Data Transparency

    One thing is worth noting. We have examined energy

    efficiency for schools in several states and we have

    never had as much difculty receiving public data as we

    did in North Carolina. At one end of the transparency

    spectrum were ofcials at Buncombe County Schools,

    who provided the data within one week of our request

     – one of the best responses we have seen.

    At the other end of the spectrum, however, were

    officials at Wake County and Iredell-Statesville.

    Requests were made at the end of the 2014-15 school

    year, both so we could get a complete school year, and

    so other school-related demands would be reduced.

    Despite that courtesy, Wake County ofcials provided

    the data three months later and the electricity data

    appeared incomplete. Meanwhile, Iredell-Statesville

    officials provided printed copies of the electricity,

    natural gas and sewer bills in a large cardboard box.

    Having worked at a state agency that had to respond to

    many public disclosure requests, we certainly understand

    the time and effort it takes to compile requested

    information. We also understand that school districts

    are not staffed to respond to such requests on a regular

     basis. The wide gap in response time between districtswithin the state, however, indicates the problem with

    compliance had less to do with staffing or time than

    with the simple failure of school ofcials to prioritize

    transparency.

    It was the most difcult time we have had in receiving

    data that should be readily available from public

    institutions.

    Buncombe County School District

    Buncombe County school district has two green

    schools.9 Both are Intermediate schools that serve

    children in grades 5 and 6. In total the district has

    10 middle and intermediate schools. To ensure our

    comparisons are accurate, we compared the green

    intermediate schools to the performance of other

    Does the energy use of green buildings justify their signicantly

    higher construction and operating cost?

    schools of similar size and type in the same district.

    Here are our ndings.

     Joe P. Eblen Intermediate School 

    During the 2014-15 school year, green-designed Eblen

    Intermediate School used 6.2 kilowatt hours (kWh) per

    square foot and 13.7 cubic feet of natural gas per square

    foot. The school uses little natural gas, ranking second

    in the district for natural gas use per square foot, but is

    second-to-last in electricity use, ranking ninth out of ten

    middle/intermediate schools.

    On a cost basis, Eblen spends 77 cents per square foot for

    energy, ranking it 6th out of the ten schools in the district.

    As noted above, Eblen spends seven percent more than

    the non-green middle schools in the district and 20

     percent more than the most efcient middle school in the

    district, Valley Springs Middle School, built in 1989.

    One reason older schools use less energy is that

    they have fewer power draws and can have poor

    air conditioning systems, making the buildings less

    comfortable. Clyde A. Erwin Middle School – built

    seven years earlier than Eblen in 2004 – uses nine

     percent less energy per square foot.

    Far from using 30 percent less energy – as the designers

    claimed – Eblen uses more energy than most other

    equivalent schools. If Eblen were simply as efcient asthe average of the other schools, energy costs would be

    $5,746 lower per year.

    Looking at the best scenario, the difference between

    Eblen and the worst-performing school, North Windy

    Ridge, is also very small. Eblen only uses about ve

     percent less energy than North Windy Ridge. Bringing

     North Windy Ridge up to the standards of Eblen would

    have saved the district only about $3,800 a year, or

    $76,000 over the typical 20-year lifespan of a school

     building. For a building that cost about $14 millionthat represents a savings of one-half of one percent

    Typically green schools cost at least two percent more

    to build, meaning the undiscounted loss would be

    $204,000 in the best circumstances.10

    However, since Eblen actually performs worse than the

    average building, the additional cost to meet the LEED

    standards will likely never be recovered.

    Charles T. Koontz Intermediate School 

    Built at the same time, using the same green approach,the energy-use numbers for Koontz are almost identical

    to those of Eblen Intermediate School.

    During the 2014-15 school year, Koontz Intermediate

    School used 5.8 kilowatt hours (kWh) per square foot

    and 14.8 cubic feet of natural gas per square foot. The

    school uses little natural gas, ranking third in the district

    for natural gas use per square foot, but ranks seventh

    out of ten middle and intermediate schools in electricity

    use. On a cost basis, Koontz performs slightly worse

    than Eblen, spending about 77 cents per square foot

    for energy use, making it the seventh-best school in the

    district for energy efciency.

    As in the case of Eblen, the additional cost to meet

    the LEED green building standards did not yield

    the promised energy savings. Ultimately the district

    spent more money to construct buildings that are less

    efcient.

    Green school advocates offer a number of explanations

    for why buildings fail to deliver promised energy

    savings. We will discuss these reasons in detail below but one is worth mentioning here. New buildings –

    green and traditional – often have more amenities,

    including air conditioning and more electrical outlets to

    accommodate computers and other equipment. Green

    school advocates, then, claim that new schools are more

    comfortable and more accommodating than traditional

    schools. For this reason, they might argue, comparing

    a school built many years ago to one built today is

    invalid.

    There are a couple of problems with these justications.

    First, ve of the other eight schools use less energy, so

    any justication may account for some, but not all, of

    the discrepancy.

    Second, labeling the schools as “green” implies they are

    more energy efcient and have a smaller environmental

    impact than other schools. Arguments that attempt to

    explain away additional impact on the environment by

    citing added amenities demonstrate that the adjective

    “green” is less important than other design goals, like

     building comfort. It is hard to continue to call these“green” buildings when the designer has sacrificed

    reducing environmental impact in favor of other,

    energy-using priorities.

    Compared to the promised savings, neither of the

    green intermediate schools in the district perform as

     promised. Given these poor results, it is likely that

    spending additional school funds to meet the green

    standards would not be a benecial public expense.

    Iredell-Statesville School District

    There is only one LEED-certied elementary school in

    the Iredell-Statesville school district, but it holds the

    distinction of being “the rst elementary school in the

    nation to be certied as a LEED Gold building.”11 Built

    in 2002, it is older than many green schools around the

    country and provides a good opportunity to see whether

    green certication stands the test of time, especially

    since this school was built to such a high standard.

    We compared Third Creek to other elementary schools

    in the district for the period of July 2014 to April 2015

     because some schools did not provide data for May

    2015. Additionally, we eliminated schools for which

    data were unavailable or incomplete. Ultimately, we

    compared 14 of the 17 schools and the data show a

    wide range of energy performance. The chart shows theelectricity and natural gas use per square foot for each

    of the 17 schools we examined.

    The schools range in size from 51,698 square feet to

    108,960 square feet. Third Creek Elementary School is

    toward the upper end at 94,000 square feet. There does

    not, however, appear to be a relationship between the

    size of the school and per-foot energy use.

    Third Creek Elementary

    Of the 14 elementary schools, Third Creek Elementaryranks 11th in total energy cost per square foot, spending

    80 cents per square foot over the course of the year

    It spends about 12 percent more for energy than the

    average elementary school in the district, and about 60

     percent more per year than the best-performing school

    Shepherd Elementary.

    Overall, Third Creek Elementary spends about $7,775

    more per year on energy than it would if it were as

    efcient as the average elementary school in the district.

    Over the 20-year lifespan of the school, that would

    mean an additional $155,500 in energy costs.

    Additionally, the school cost $8,749,600 to build

    in 2002.12  Applying the conservative two percent

    additional cost for green buildings – especially since

    it met a high standard – added about $171,560 to the

    total cost. If the school saved energy early in its life,

    it certainly is not doing so now, meaning the district

     probably did not recover the additional cost to meet the

    LEED Gold standard. Between additional construction

    costs and energy costs, Third Creek Elementary will

    cost the district an estimated $327,000 more in energy

    use.

    The district does not have another LEED-certified

     building, so administrators may have recognized that the

     promised “green” benets do not match the additionalcosts when building and remodeling schools in recent

    years. Given its age, the high level of certication it

    received and its performance, Third Creek Elementary is

    a warning to other school districts about the gap between

    the promise and reality of building “green” schools.

    Durham School District

    There are several LEED-certified schools in the

    Durham school district, including two buildings that

    meet the LEED Gold certification level. Two of the

    green schools are elementary schools, and with 30

    elementary schools overall, they provide an excellent

    opportunity to compare the energy-saving performance

    of the LEED certified schools to traditionally built

    schools.

    The two green schools are W.G. Pearson Elementary

    School, which received the lowest level of LEED

    certification, Silver, and Sandy Ridge Elementary

    School, which is certied at the LEED Gold level – the

    second highest level available.

    Although there are 30 schools in the district, we have

    chosen 28 for comparison, all of which purchaseelectricity from Duke Energy and natural gas from

    PSNC Energy. The other two schools – Little River

    and Mangum – purchase their electricity from other

    sources. As a result, their rates and other price variables

    may be different. If there were more diversity of

    utility suppliers among the schools, we would include

    them, but since these two schools are outliers, the best

    approach to obtaining an accurate apples-to-apples

    comparison is to choose the 95 percent of elementary

    schools that use the same utility supplier.

    Additionally, most of the schools have similar ratios ofelectricity and natural gas use. Only one school, Glenn

    Elementary, uses only electricity. Finally, the schools

    are, for the most part, similar in size.

    Sandy Ridge Elementary School 

    The data from the most recent school year, 2014-

    15, shows Sandy Ridge Elementary, which is LEED

    Gold certied, actually ranks 15th out of 28 schools,

    or slightly below average. It uses about 37 percent

    more energy than the best-performing school, Holt

    Elementary, which was last remodeled in 1992.

    Comparing it to more recently-built schools, Sandy

    Ridge uses about 3.5 percent more than Creekside

    School, built in 2004 and remodeled in 2010.

    The construction cost for Sandy Ridge School, includingfor the landscaping and parking lot, is reported at

    $15,357,880.13 Using the two percent cost increase

    average, meeting LEED standards would add about

    $301,133. This is probably low, because two percent is

    the average for LEED certied buildings and estimates

    show that meeting LEED Gold is much more expensive

    to achieve.

    Additionally, if Sandy Ridge were as energy efcient

    as Creekside, it would save the district an additional

    $4,282 per year. Over the 20-year lifespan of the building, it will spend an estimated $85,650 more than

    if it were as efcient as Creekside.

    Ultimately Durham Public Schools will spend nearly

    $400,000 more for a building that is supposed to be

    more energy efcient, but actually performs worse than

    the average school.

    W.G. Pearson Elementary School 

    Pearson Elementary School performs better than Sandy

    Ridge School in energy use, despite actually achieving

    a lower level of LEED certification. Out of the 28

    elementary schools we examine here, Pearson ranks

    tenth overall, just behind Creekside School, which rankninth.

    Both schools perform significantly worse than Hol

    Elementary which was last remodeled in 1992 and

    spends about 34 percent less on energy than Pearson

    and 37 percent less than Sandy Ridge. Southwest

    School is next-best, and was constructed in 1991. The

    fact that the two most efcient schools were built within

    a year of each other indicates the builders at the time

    were focused on efciency.

    It is also likely they use less energy because they were

    designed with fewer electricity draws than newer

    schools. This is likely in the case of Pearson Elementary

    Pearson ranks fth among the 28 elementary school

    we looked at for natural gas use, but sixteenth in use

    of electricity per square foot. It seems likely that the

    increased electricity use is due to the inclusion of more

    electrical equipment or more outlets for such equipment

    Interestingly, results for Sandy Ridge show the opposite

    It ranks 11th overall in electricity use per square foot

     but 21st in natural gas use. There is no obvious reason – other than the fact that the LEED Gold certication

    simply is not delivering on its promises – that the

    school would perform so poorly.

    Ultimately Durham Public Schools’ green elementary

    schools do not live up to their alleged distinction

    Compared to other elementary schools in the district

    their level of energy efciency is about average. Indeed

    they perform slightly worse than Creekside Elementary

    which was built and remodeled in recent years but did

    not seek or receive LEED “green” certication.

    In such circumstances it is our experience that some

    school districts justify the additional cost of building

    “green” by pointing to other amenities. That may or may

    not be true, but at the center of “green” claims about

    LEED buildings is that they are more environmentally

    friendly by saving energy, that the higher cost is worth

    it because they are helping to save the planet. Tha

    Ultimately Durham Public Schools’ green

    elementary schools do not live up to their

    alleged distinction.

    is not the case with Durham’s two green elementary

    schools.

    Wake County School District

    The largest school district we examined, the Wake

    County Public School System, has one LEED-certied

    “green” school, Alston Ridge Elementary School,

    out of nearly 100 elementary schools in the district.

    Alston Ridge was certied LEED in 2013. It received

    the lowest level of certication, Silver, and it received

    very few of its points in the Energy and Atmosphere

    category.14 For this reason we would not expect to see

    the building perform signicantly better in energy use

    than other schools, since certification was achieved

     by scoring points in other categories like “Indoor

    Environmental Quality” and “Water Efciency.”

    Although there are many other elementary schools inthe district, comparing the performance of Alston Ridge

    to other schools is difcult due to inconsistent data. For

    example, half of the schools provided no data related

    to electricity costs. Additionally, while virtually all

    schools reported natural gas data, the cost per square

    foot varies signicantly, with some schools paying six

    times as much as others. One reason for these anomalies

    could be that meters are shared by schools or different

     buildings and are, therefore, allocated to other schools

    To address this, we focused only on natural gas data

    The data fall within a general range and with the large

    number of schools, they help minimize the impactof outliers. About 90 percent of the schools have

    natural gas bills that fall between ve and 15 cents per

    square foot. This provides a fairly consistent basis for

    comparison.

    Additionally, we also focused on the other new

    elementary schools built as part of the district’s 2006

    Community Involvement Program to build and refurbish

    district schools. There are eight new elementary schools

     built during this project for which we have data.

     Alston Ridge Elementary School 

    The only LEED-certied school in the district, Alston

    Ridge opened in 2010 and was certified in 2013.15

    At nearly 105,000 square feet, it is about 15 percent

    larger than average, but within the typical range for

    elementary schools.

    Certified ‘Green’ Schools

    For the most recent school year, Alston Ridge spent 11

    cents per square foot for natural gas, exactly the average

    amount for all the elementary schools in the district.

    Additionally, compared to new elementary schools built

    as part of the district’s 2006 Communty Involvement

    Program (CIP 2006) building program, it uses slightlymore natural gas per square foot.16 Herbert Akins Road

    Elementary is an outlier at 22 cents per square foot,

     but all other elementary schools built as part of the

    CIP 2006 program have costs ranging from 11 cents

     per square foot down to nine cents per square foot, for

    Walnut Creek Elementary School. Alston Ridge spends

    about $1,300 more per year than the average of the

    other new elementary schools built under the CIP 2006

     program.

    As we mentioned, electricity data are inconsistent for

    these schools. For example, although Alston Ridge

    reported more than $59,000 spent on electricity and

    lighting in 2014-15, none of the other schools reported

    more than $15,000 in those areas. Focusing only on

    natural gas provides a level playing eld for comparison

    of all these new schools.

    Additionally the building cost $24,469,718 for

    construction, putting the LEED certification cost

    estimate at about $479,800.17 The district achieved

    the lowest level of LEED certication and appears to

    have chosen low-cost methods to meet the standard. Asa result, the additional cost may be closer to the two

     percent of budget or even lower. Whatever the level, the

    school is using more natural gas per square foot than

    comparable elementary schools in the district.

    As we noted above, it is not surprising that we do

    not see signicant – or indeed any – energy savings

    from Alston Ridge, because of the focus on earning

    LEED points outside the energy efciency area. That

    conclusion is borne out by the data.

    North Carolina Green Schools – The Results

    Of the four North Carolina school districts examined by

    this study, none have green schools that help “protect

    the environment” as their promoters had promised.

    Further, none of the schools will come close to energy

    savings that recover their higher initial construction

    costs, and most schools are less efcient than their non-

    green counterparts located in the same districts.

    Results are fairly consistent across the districts. None

    of the green schools are best-performing in energy use,

    and in every school district at least one of the green

    schools performs below average, compared to similar

    schools in the same district. Ironically the two LEED

    Gold schools, LEED’s second-highest ranking, in thisstudy perform worse than the average school in their

    districts. Given the difficulty of meeting that green

    standard, we would expect to see above average levels

    of energy efciency, since they cost so much more to

     build.

    The consistent failure of green buildings to produce

     promised energy savings is not unusual, as we noted

    above. The performance of North Carolina’s green

    schools, however, is a further indication that legislators

    and school ofcials should think twice before requiring

    schools to spend additional taxpayer and school dollars

    to earn LEED certication. The experience of schools

    across the country demonstrates that district facilities

    directors are often adept at nding cost-effective ways to

    reduce energy use, based on the particular buildings they

    manage. Requiring them to meet a formulaic, one-size-

    ts-all approach, however, often leads them in the wrong

    direction, increasing costs without returning savings.

    Our discussions with facilities directors in North

    Carolina, and the fact that some districts have not

    sought LEED certication for new schools, indicatesthey have been unsatisfied with the results of green

    schools.

    The failure of green buildings to produce energy

    savings as promised is also an environmental failure.

    Many advocates who promote LEED or similar rating

    systems point to the supposed carbon dioxide emission

    reductions achieved by green schools. The failure to

    save energy, or even slow the increase in energy use,

    wastes resources on efforts that do nothing for climate

    change or the environment. Instead misguided green building rules divert scarce funding from efforts that

    could have a positive environmental impact, or which

    could be used to fulll other public needs.

    Ultimately – for taxpayers, students and theenvironment – the real-world data shows that NorthCarolina’s green schools fall well short of their energy-saving promises.
