Arlington Greens Release Lecture on U.S. LEED Green Buildings by Oberlin college professor Scofield, Finding Minimal Environmental Benefit

Development,environment — @ 3:39 pm

June 15, 2020

The Arlington Greens announced today the release online of a talk on March 2 in Arlington by Oberlin College of Ohio professor John Scofield, a national expert on green building technology, on his research into marketing claims that green-certified buildings such as the LEED rating significantly reduce carbon emissions.  EcoAction Arlington, an Arlington environmental non-profit organization, co-sponsored the talk held at the Arlington County public library with the Arlington Greens.  The Arlington Independent Media and Miriam Gennari of the Sustainable Scoop recorded the talk and interviewed professor Scofield.

Professor Scofield used energy data from hundreds of thousands of commercial buildings in ten major U.S. metro areas to examine if energy certifications like LEED (a trademark meaning “Leadership in Energy and Environmental Design”) significantly reduce carbon emissions over non-certified comparable buildings.  His findings demonstrate very small, almost negligible carbon savings.  Scofield found that carbon emissions reductions in LEED buildings are quite modest, generally well below 10 percent, and well below marketing claims of over 25 percent.

The research finding that LEED and other similar commercial building energy rating systems save only negligible amounts of carbon emissions is an important environmental policy issue for Arlington County and for many other U.S. communities.  Over 40 such certified buildings in the county got generous subsidies based on now discredited claims of substantial carbon emissions reductions.  Arlington County subsidies for bogus green energy technology wastes county funds which should be used to incentivize proven effective green technology that does substantially reduce carbon.

In 2019, the Arlington County Board approved a community energy goal that the county become carbon neutral within 25 years.  About 80 percent of carbon emissions in the county occur in commercial and residential buildings, and thus the county’s goal can only be achieved by large carbon emissions drops in buildings.   The county government’s past reliance on LEED and similar energy certifications to reduce energy use in commercial buildings now appears to be wrong.

Tear downs and Large Energy Wasteful Houses Contribute to Rising Carbon Emissions in Arlington

Development,environment — @ 4:31 pm

Energy use in Arlington for homes has been rising over the past few years, in part fueled by more residents but also by changes in the size of new houses being built, particularly detached houses.  The 9-percent rise in residents in Arlington during 2010-18 increased use of electricity and natural gas in apartments and houses, but so did having more new McMansions.[1]  During 2010-18, residential use of electricity in Arlington rose 3 percent to 809 million kilo watt hours (kwhs), while use of natural gas rose 28 percent to 91 million therms. [2]

The average house in the United State has about 1,971 square feet of living space; the average house in Virginia is slightly larger at 2,227 square feet, according to the U.S. Department of Energy.[3]  The larger the living area, the more energy is required to heat, cool, and power devices and appliances in that space.

In Arlington over the past decade or so, more and more older detached houses, generally with under 1,500 square feet of living space, are torn down, and replaced by a new 4,000 or larger square foot house.  In 2019, the number of such tear downs amounted to 158.[4]

While the new house may have better insulation and often more energy saving appliances than the demolished house, the much larger living space overwhelms any such energy efficiency savings.  Studies of energy use in U.S. houses indicate that a 4,000 square foot house uses about 160 percent more electricity than a 1,500 square foot house, and about 76 percent more natural gas, as outlined here.[5]

Energy use by size of house in the United States:

Size of house                   Electricity    Natural gas    Combined Carbon 

(Annual in kwhs)  (Annual in therms)    (Metric tons)

Average 1,500 ft2 house     12,000                   10                       8.9

Average 4,000 ft2 house     31,200                   18                     22.0

Increase (percent)               160                          76                      146

 

From a carbon emissions basis, the larger house uses 146 percent more carbon than the 1,500 square foot house.   The larger house is 167 percent larger in living space, but uses about 146 percent more carbon.  Thus, standard building or appliance efficiency does not overcome the effects of the larger living space.   A new larger house would need to cut its emissions by 146 percent and that would require solar panels, much better insulation, geothermal heating and cooling, and other passive building technology.

Greens ask Virginia General Assembly to give Arlington local powers over energy/environmental building codes

Development,environment — @ 5:55 pm

At the January 7 meeting, Arlington Greens agreed to ask Arlington state delegates and state senators to support granting Arlington County local powers over energy/environmental building codes so that Arlington can achieve carbon emissions cut set by Paris Climate Treaty.  We ask that Greens and community members also contact their delegates and senators to support this common sense environmental legislation:

Petition to Arlington state delegates and state senators, January 2020 on allowing local authority to achieve environmental/energy plan

To:   Virginia General Assembly Delegates Patrick Hope, Alfonso Lopez, Mark Levine, Rip Sullivan, and State Senators Barbara Favola, Adam Ebin, and Janet Howell:

As residents of Arlington, we ask that you support environmental legislation in this session of the General Assembly that would allow the Arlington County Board of Supervisors to modify the existing Virginia building codes so as to strengthen energy savings and environmental protection for any buildings in Arlington.   We ask that Arlington be permitted a local option to override Virginia State building codes so that Arlington can fulfill its Community Energy Plan that would meet the required carbon emissions stipulated in the Paris Climate Treaty.  The Arlington County Board approved its community energy plan in September 2019, but does not have the full authority under state law today to implement it.

The Virginia Board of Housing and Community Development (BHCD) has repeatedly failed (as recently as 2017) to approve the minimal International Environmental Conservation Code that would have achieved at least a 30 percent savings in energy use in new buildings, and thus new buildings in Virginia are very energy wasteful.

Arlington County needs authority to require builders of new structures to meet stringent energy savings including carbon neutral buildings, mandating geothermal and solar voltaic panels, enhanced insulation, among other features in order to meet its community energy plan goal to have a carbon neutrality goal by 2050.  It cannot do this since 80 percent of carbon emissions in Arlington occurs in buildings without stricter building codes.

We therefore act that authority be delegated to Arlington County or to any other jurisdiction that may also want to implement its own strict environmental energy plan (such as the City of Alexandria) to strengthen building codes so as to achieve energy savings and thus meet environmental goal on carbon emissions.

Greens support temporary halt to new buildings in Arlington until energy plan is approved

Development,environment — @ 12:20 pm

Arlington Greens voted at their meeting on Nov. 6 to support a petition to the Arlington County Board to temporarily halt new building construction permits until the county board is able to approve an effective Community Energy Plan that will force buildings to have green building and green energy in all new buildings.

The County board in September passed a partial Community Energy Plan (CEP)that sets out the goal that Arlington will be carbon neutral within 25 years or so, but that plan had no funding or building zoning changes that would have compelled new buildings to meet this high green energy standard. New buildings–residential or commercial–will last often over 40 years, and using current wasteful, carbon-based electricity and heating will mean no reduction in carbon emissions from them for the next 40 years.

The County Board has promised to enact the full CEP by June 2020 that will include changes in building codes so that the environment and carbon emissions can be improved. The county needs to halt giving out building permits until the June CEP is approved. Amazon has proposed building two towering high rises in Pentagon City–these should NOT be approved until we have a full CEP.

Arlington Judge Blocks Historic Preservation of Westover Apartments

Arlington Judge William Newman ruled against community efforts for historic preservation in Westover on September 29. We had asked him to require the county to complete our historic petition for Westover, but the judge says the county can take as many years or decades as it chooses to complete historic review even if all the buildings are lost. He dismissed our lawsuit without even a full hearing on the merits.

Judge Newman—a Democrat and former member of the county board himself— ruled that the county can delay forever in processing our historic petition forever. He did not even have the sense of justice to allow us to argue our case with evidence at a trial. He dismissed our case with prejudice (meaning we can never re-file).

He ruled that the county does not have to proceed at all on our historic petition which was filed about 3 ½ years ago. Since we filed our historic petition, four apartment buildings were demolished in addition to seven demolished before.

It is ironic that Judge Newman is married to a billionaire and lives in a mansion on an estate in Middleburg Virginia worth many tens of millions of dollars, and ruled that it is okay for the county government to allow the demolition of 70-year old apartments that house renters who live on very small incomes. There is plenty of room in Arlington for millionaires and billionaires living in their big mansions, but no room for a disabled veteran, a school aide or a library technician getting by on under $50,000 a year.

It is a lousy and unfair justice and political system that values billionaires and developers over modest people living in Arlington. Justice deferred is justice denied. This is not justice.

We cannot appeal the judge’s egregious decision to the Virginia Supreme Court since this would cost us at least $15,000, and we can never recoup any of these legal fees even if we were to win our case. So our justice system works well for the rich and developers, but not for ordinary people in Arlington.

With our court case thrown out, we asked the county board itself to bypass the local historic review board and take up the matter itself and give us a final decision. But this is highly unlikely as the board is in league with developers who choose to demolish older and simpler homes and build new, bigger, more energy wasteful, and expensive homes for the rich. And we wonder why we have an affordable housing problem in Arlington.

We will continue as best we can to preserve Arlington along with modest apartments for middle and working income people in Arlington.

Arlington’s Energy Plan to reach zero carbon emissions based mostly on hot air and platitudes

Development,environment — @ 11:17 am

Arlington County Board of Supervisors on September 21, 2019 updated its six-year old Community Energy Plan (CEP), and increased its goal from a 75-percent reduction in carbon emissions within Arlington County by 2045 to net carbon neutrality by 2050. The actual policies needed to do this will be considered in a separate implementation policy in June 2020. So for now, the CEP is merely hopes and not concrete actions to be taken.

Why did the county only approve goals but not at the same time the means to achieve these goals? The plan has no funding nor new county ordinances or requirements. The plan calls for the county government to use only renewable power within 6 years, and all residents and business to use only renewable power by 2035.

The problem with that is that Virginia today has NO commercial renewable electricity. In 2018, about 3.1 million megawatts of electricity were consumed by commerce, residents, and government in Arlington. To supply that amount of electricity would take the electricity generated from the largest wind tower farm in the world (the London array with a daily capacity of 7,120 megawatts) for the +200,000 residents of Arlington.

Dominion Energy proposes to build a large wind farm off Virginia coast by 2026 with a capacity of 2,600 megawatts daily capacity that could supply only one-third of Arlington’s electricity use today.

It can argued that the 2013 CEP failed on nearly all of its goals, although some external and market driving factors did allow county emissions to drop slightly. A large proportion of existing office space became vacant during 2007-18, and Dominion Energy began phasing out coal-fired electricity for natural gas-fired electricity which produces less carbon emissions.

During 2010-18, net carbon emissions from buildings did drop by 4 percent or very close to the 2013 target of a 5-percent drop but only because of high rates of office vacancy. The bad news and more foreboding is that carbon emissions in residences rose by 14 percent, driven in part by a 9-percent increase in county residents.

The 2013 CEP failed owing to several factors: the State of Virginia Building code for new residential units was not strengthened to require builders to achieve a 30-percent energy savings. Secondly, no cogeneration power plants were built in Arlington that would have reduced commercial use of natural gas and electricity. Third, even the LEED certified buildings added in Arlington did not achieve significant energy savings.

Arlington Green Building Certification Program Mostly Green Washing

Development,environment — @ 4:06 pm

Arlington County gives subsidies to builders who obtain LEED certification for a new building that is supposed to cut energy use by 25-30 percent. The main subsidy given is zoning approval to add more floors and height to a new building, and in some cases tax credits. The first building was certified in the Arlington program in 2006.

During 2006-16, about 89 buildings were built in Arlington with a so-called “Green building certification” that include mainly LEED (Green Building Council), Earth Craft, Energy Star, and Water Sense EPA. But in the 13 years that program has operated, County staff have been unable to verify that these certified buildings use less energy than comparable non-certified buildings.

Nationwide, independent researchers cast doubt that LEED or similar rating systems result in any significant energy reduction. One researcher obtained energy use data for 10 major metro areas with large numbers of green certified (mainly LEED) buildings, and found that these building use MORE energy than comparable non-certified buildings, according to research from Oberlin College professor John Schofield. Perversely, he found newer LEED buildings tend to host more energy intensive activities, such as more computers and cellphones.

Thus, although Arlington has about 90 more energy certified buildings, it is not apparent that these buildings actually use less energy, and based on more comprehensive studies of ten major metro areas including Washington DC, such building would be expected to use more energy and not less.

There are proven ways to reduce energy in commercial buildings but these largely involve external factors—addition of solar panels outside the building, geothermal heating and cooling, and sourcing of renewable electricity.

The county government should revise its green building program to require developers to use external technology rather than rely on a certification program that results in no or even higher energy use. The current county program is green washing: allowing a developer to claim public relations credit and a significant subsidy for doing nothing to cut energy use.

Arlington carbon emissions rise in homes, but drop in commerce and government during 2010-18, with 4-percent overall drop

Development,environment — @ 4:32 pm

During 2010-18 in Arlington, the use of natural gas rose by 30 percent to 91 million therms while use of electricity fell by 9 percent to 3.1 billion kilo watt hours, according to data from the Arlington County Government. In terms of carbon emissions, total carbon emissions declined by about 4 percent during 2010-2018, but most of this occurred because of lower commercial and government use related to fewer office workers in Arlington.

Residential use of electricity and natural gas both rose in this period. Use of electricity in homes rose by 3 percent to 1.7 billion kilowatt hours, and use of natural gas by rose by 54 percent to 61 million therms. Combined carbon emissions in residences rose by 14 percent to about 1.1 million metric tons of carbon. Raw data were supplied by the county government and converted to carbon equivalents using EPA data.

The increased residential use was propelled upwards by a 9-percent rise in population of Arlington rising to about 226,000 in January 2019 from 208,000 in 2010. However the rise in energy use exceeded the rise in population indicating that residents are intensifying their use of energy in their homes.
For the commercial and government sectors which experienced a drop in gas and electricity use, the large increase in empty office space and the reduction in the number of federal employees located in Arlington triggered this decline.

With the expected entry of thousands of Amazon employees in Arlington over the next 5 years or so, it is likely that the commercial sector will return to its prior energy use as office space is filled and more office buildings are constructed.

The Arlington Community Energy Plan adopted in 2013 has thus yet to indicate a shift in the energy patterns in commerce, government and residential uses, and the slight 4-percent drop in carbon emissions is entirely related to increased office vacancies. A return to high office use and the entry of Amazon HQ2 is likely to lead to a rise in overall county emissions. This will make impossible Arlington County’s energy plan goal to attain a 50-percent drop in emissions in the next 20 years.

Lawsuit filed against Arlington County for Blocking Historic Preservation of Westover Village in Arlington

John Reeder, a longtime Arlington community activist and chairman of the Arlington Green Party, filed a lawsuit on July 30 against the Arlington County Board of Supervisors for their refusal to complete the historic preservation review of Westover Village Apartments begun three years ago. The lawsuit asks an Arlington County judge to order the County Board to complete the local historic review process, as required under Virginia’s historic preservation law. Local historic preservation would prevent any further demolitions of existing buildings.


Digital Camera

Westover Village containing garden apartments, a shopping center, schools, a church, and small detached houses, was built mostly during the World War II era for Arlington residents working for the U.S. military and Government; most residents today are renters in the remaining about 700 moderate-cost garden apartments. The National Trust for Historic Preservation in 2006 designated the Village a national historic district, owing to its historic significance and architecture of the late 19th and 20th Century Revivals/Colonial Revival. In the past few years, a developer demolished eleven apartment buildings with about 90 units, and eliminated all adjacent mature old trees and green space.

The petition to initiate the local historic review of Westover Village was filed by Reeder in June 2016, and later supported by 160 Arlington residents. The county Historic Affairs and Landmark Review Board (HALRB) then found that the proposed historic district met at least two of the required criteria for local historic designation. But then later, the HALRB halted any the review until the county board completed an unrelated zoning ordinance (the Housing Conservation Districts) that remains unfinished today. The proposed zoning ordinance was a pretext for delay, and unrelated to local historic designation which must strictly conform to the State of Virginia law on historic preservation.

The lawsuit asks for no monetary compensation, but rather for an order from the judge compelling the county board to expeditiously complete the historic review process after a 3-year delay as required by state law. Eleven buildings in the Village have been demolished to date, four since the petition was filed three years ago.
