The Providence Journal just published an op-ed I wrote regarding how long term contracts for clean energy can help reduce costs and risks for electric utility ratepayers.

The Providence Journal reports that Rhode Island Tea Party was permanently banned from participating in the oldest Independence Day parade in the nation for the heinous crime of handing out free copies of the US Constitution.
A quick check of the parade rules doesn’t make it evident that handing out free copies of the US Constitution would be grounds for permanent barring from the parade. (at least they didn’t when this was posted). Perhaps those rules will be quickly changed when the press gets a hold of this story.
I wonder what it is those folks on the parade committee think they are celebrating with all their flag waving. Someone on the Bristol parade committee should perhaps read one of those copies of the Constitution that upset them so much. I’d suggest they pay particular attention to the First Amendment.
At least this story is getting coverage in the popular press, unlike the trampling of the Constitution that seems to be an increasingly preferred means of expediting politicians favored outcomes in Washington these days.
Here in Rhode Island, as elsewhere, well-intentioned people are proposing legislation that would mandate that any public building or any building receiving public subsidy be LEED rated. I already addressed my concerns with that proposal in “Legislating Greenness”. The problems include:
1) Empowering a single private out of state organization with essentially unregulated monopoly powers to define, change, certify and charge for greenness certification, which is effectively being mandated as a building code standard.
2) Eliminating market based competition and real market signals for defining, evolving and improving green building standards and practice.
3) In the only study ever done on LEED buildings, when rigorous statistical analysis was applied to the data in an independent review, it ended up that at least to date, LEED buildings actually have used more energy than typical buildings.
Perhaps the biggest problem is that rating systems like LEED add more layers of complexity and more fees for LEED professionals, architects, engineers and construction managers, but they don’t add any meaningful accountability to the system. That’s exactly why LEED buildings can use more energy than conventional buildings and why LEED rated skyscrapers can leave their lights on all night when nobody is in the building. Once the rating is determined based on design, the building can call itself green no matter how poorly it actually performs.
With the economic situation we are in, the goal of green building advocates has to go beyond putting plaques on walls and having nice things to say in the press. We know that real green buildings actually save energy and save significant amounts of money in their operation. We need real accountability and serious incentives to make that happen.
So lets stop counting points and instead focus peoples attention much more clearly with a measurement we all understand very well – dollars.
The way states fund new buildings needs to be changed. Rather than coming in as an allocation or grant of cash, half the funding should be delivered as it is now under current funding mechanisms and the other half should be delivered to the agency or municipality building the building as a short term zero interest loan with a two year balloon payment. That loan would be forgiven given after two years of operation if gas, oil and electric bills are 25% lower in energy units used per square foot than on comparable existing buildings in the state. If the building doesn’t meet this goal, the agency, municipality or other recipient of the funds would have have to repay the loan in full.
Such serious incentive would focus attention on what actually matters far more than counting greenness points.
With financial incentives that very clear and serious, the building procurement process for new buildings would quickly evolve to requiring energy performance bonds from architects and general contractors which would focus their attention very clearly. Architects and contractors would quickly become more serious about details. Schools would have to start training architects and engineers on issues that actually matter. Companies that failed to deliver would have a hard time getting energy performance bonds for future projects. The market would start providing real significant rewards for real green building.
Building operations and maintenance staffs would have more prestige and be considered a far more important part of organizational management with serious money on the line for real measured building performance.
Among other benefits, this kind of legislation would require getting baseline data on the existing building stock. The process of collecting and comparing real baseline data would get the state and municipalities comparing their existing buildings to each other on very simple and easy to calculate metrics – annual therms, gallons of oil and kWh per square foot. It would immediately become very obvious which buildings need to be fixed.
Both through improving the worst performing buildings and building new buildings that use 25% less energy than baseline, the goals and minimum performance levels constantly and automatically reset higher toward better performing buildings.
Such a system doesn’t need “Accredited Professionals” using abstract rating systems to count points. All that is needed is the utility bills that get delivered every month anyway.
Henry Gifford deserves credit for inspiring the concept that buildings should be rated on actual performance as measured by utility bills. All that is needed is add some real accountability to that very clear and simple rating system.
The situation or country is in regarding energy, the environment and the economy is serious. We need serious incentives and serious penalties to drive serious solutions.
I have dedicated my entire three decade career to green building and renewable energy.
The markets for these solutions have been growing at a blistering pace. In the case of solar photovoltaics, annual worldwide growth has averaged approximately 40% for a decade. Lately, with increased interest in government as a solution to all problems, there is accelerating pressure to push growth in these spheres even harder through policy mandates.
This may be possible with relatively straight forward challenges like installing more solar panels or wind generators. Unfortunately, in the case of complex issues like improving the performance of buildings, we don’t have nearly adequate levels of skilled experienced practitioners necessary to implement the idealized goals of well intended people who seem to think that simply mandating solutions actually solves problems.
The questions of if and how to best use public policy to encourage green building practice have been going on for a very long time in the professional community and are still very much unresolved. My own sense is that the market demand for these solutions over the last several years has been very successful in spurring remarkable growth and success for those providing green building solutions.
I am not at all convinced that mandating greenness will actually improve buildings. And like most hastily implemented good intentions, such measures could have significant unintended consequences.
The following is derived from a discussion of testimony I presented recently at a State Senate hearing here in Rhode Island regarding attempts to enshrine the US Green Building Council (USBGC) Leadership in Energy and Environmental Design (LEED) standards as public law.
I have the utmost respect for all USGBC has done as a marketing effort to promote green building and for LEED as a set of voluntary design guidelines, which it was originally intended as.
But I have very serious reservations about mandating that a private out of state organization like USGBC be enshrined with essentially carte blanche authority to design, price and enjoy an exclusive monopoly on verifying compliance with a significant aspect of state law. Such efforts that cross the appropriate line between public and private spheres in such critical areas of regulation are just bad public policy.
And with statistical proof from USGBCs own data showing that at least to date, LEED buildings have on average proven to actually use more energy in their operation than comparable buildings, we have to be careful to not let good intentions get ahead of reality. The relevant study by Henry Gifford, USGBC’s response and Henry’s rebuttal to that response are available at Henry’s web site
Henry is the mechanical system designer who has designed the HVAC systems on architect Chris Benedict’s remarkable buildings and who Chris credits with much of the success her firm has had in repeatedly building apartment buildings in New York City which use only fifteen percent of the energy of comparable buildings at no extra cost and with no subsidies. Along with his practical experience, Henry is also one of the most sought after teachers at serious professional building conferences around the country including the exclusive invitation only Westford Symposium on Building Science at which 200 of the leading building science practitioners in North America gather each summer to learn from each other.
While some are shocked by Henry’s finding, this is really not all that surprising considering the questionable methodology involved in LEED. Proof like Henry presents confirms what many of the best building experts in the country have been saying for years about LEED. Counting greenness points is really no substitute for building science; or good design, detailing and construction management; or measuring factors that actually matter.
USGBCs questionable statistical methodology in analyzing that data themselves highlights real questions about whether what is fundamentally a marketing endeavor should really be enshrined as the standards setting agency for the building industry.
Marc Rosenbaum is considered by many the leading green building consulting engineer in the country. In very publicly answering the question on the web site of the Northeast Sustainable Energy Association: “What’s the most irritating example of ‘greenwashing’ you can think of?” Marc answered “That you get your LEED rating without proving the energy performance in real life.”
Joe Lsiburek is the best known building scientist in the nation. You can find his opinion on this subject in his article Mis-LEED-ing: or his article “Prioritizing Green – It’s the Energy Stupid” which was first published in the ASHREA Journal, the publication of the nation’s professional organization for heating, ventilation, air-conditioning and refrigeration engineers.
The most thoughtful conversation I have seen on this subject is over at the BuildingGreen Blog entitled Lies, Damn Lies, and… (Another Look at LEED Energy Efficiency)
One of the critical points of this whole debate is highlighted in Henry’s own comment on that Blog. “LEED is based on a compelling idea: that anyone can take an 8 hour class, pass a test to become an accredited professional, and use a checklist or points system to profoundly improve the way buildings are designed, built, and operated. Sorry, life isn’t that simple, and neither are buildings.”

Having watched the evolution of USGBC and LEED along with Energy Star Homes, Energy Crafted Homes, R-2000 and numerous other green rating brands that have come and gone over the decades, I have developed a high degree of skepticism toward the whole idea of rating and measuring “greenness”. Rather than counting things like LEED greenness points, I am far more in favor of measuring the actual performance of buildings with hard scientific metrics like BTU/sq ft/HDD.
Henry suggests in his article: “Building energy use is perhaps the largest field of human endeavor in which almost nobody measures anything. But, the situation is actually a bit worse than that: measurements are taken by utility companies every month, and are largely ignored. Utility company records should start to be used to rate our country’s buildings immediately.”
For those who insist we must attempt to put legislated mandates and certification around this stuff, we should at least rate actual building performance and any such ratings should include verified energy use measurements and real scientific and economic metrics. Counting fairly arbitrarily determined greenness points on a design is just not appropriate for legislative mandate.
And we have to be very careful to craft legislation that separates good public intentions from the private interests of any one private organization. USGBC is a private organization that sets and changes the definitions of the LEED standards at will, sets the pricing for getting LEED certification and has an exclusive national monopoly on granting LEED certification. It would be totally inappropriate to have any standards set and enforced in that manner be enshrined in public policy. I question whether it would be constitutional if challenged.
The brand name LEED should never appear in any legislation. If it is deemed appropriate and necessary for governments to mandate green practices in building, then legislation should require specific professional and scientific standards, perhaps including requirements for energy modeling, requirements for building commissioning, requirements for building waste reduction and recycling, requirements for low VOC materials, requirements for ventilation standards, requirements for life cycle costing analysis, and other specific pragmatic details. It is a bit harder and requires real professional expertise to craft good legislation in this realm, but the extra effort is worth it.
And in setting public policy there are a variety of professional stakeholders that should be at the table sorting through the appropriate compromises rather than precluding their participation by enshrining a private organization like USBGC with arbitrary unregulated monopoly power to set public building standards.
My thirty years working professionally in the field have convinced me that doing things right in buildings unfortunately isn’t as easy as many advocates might idealistically wish for. This is very much true in the legislative and regulatory arena as well. Good legislation, like good buildings, takes real care in crafting.
My experience tells me that we should let the market sort out good designers and builders from the others. But If society insists we must regulate this stuff, there are lots of good ways to encourage green building that don’t require enshrining a single private organization with completely unregulated monopoly powers over vast swaths of the public sphere.
