An open letter to the U.S. Green Building Council (USGBC) on revealing more granular energy data from LEED buildings

 

Dear USGBC,

For the last year, as the transparency and disclosure movement has gained steam in the building products industry, we’ve heard many compelling arguments for why manufacturers should be transparent about what’s in their products. From USGBC representatives and members, we’ve heard that:

  • Designers armed with more information will be empowered to make better decisions on behalf of their projects. We need “nutrition labels” for building products.
  • It’s okay not to be perfect. The act of disclosure, of looking at what’s in your product, will lead to its own insights. The industry understands that making things involves tradeoffs and that self-awareness leads to self-improvement.
  • Participation matters. One of the biggest players in transparency has “collaborative” right in its name (the Health Product Declaration Collaborative). As we have reported, industry leaders have been fair in giving competitive programs a chance. Whatever happens on the field, we’re glad that various stakeholders are showing up to play.

It’s time for USGBC to walk the walk when it comes to energy data from LEED buildings.

We’ve made progress since 2008

A lot of people in the LEED community felt pained by the second-guessing and lawsuits that followed the 2008 New Buildings Institute study. The limitations of that data set made them a target for anyone with an agenda against LEED who wanted to make a point. We looked at the arguments and gave you the benefit of the doubt. Transparency wasn’t the buzzword yet, but it was in the air, and anyway, more data would be coming soon!

With the release of LEED 2009, you added Minimum Program Requirement #6 (MPR6), requiring energy and water data reporting for LEED buildings. You took a risk here, exhibiting leadership. A lot of people said that MPR6 was going to turn off owners, even after you promised that it wouldn't lead to plaques being ripped from buildings, and you stated that only aggregated, anonymized data would be released as a result. (Your official policy on MPR6 also stated—and still states—that data would be released regularly.)

We’ve come a long way since then. In LEED 2009, you could sidestep the MPR6 reporting requirement by saying that your building isn’t metered. Now, in LEED v4, energy meters are a prerequisite in the credit language, and through the public comment process we didn’t hear a lot of complaint about this. Perhaps that’s because things have come so farFloor-area ratio is the density of nonresidential land use, exclusive of parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential structures. For example, on a site with 10,000 square feet (930 square meters) of buildable land area, an FAR of 1.0 would be 10,000 square feet (930 square meters) of building floor area. On the same site, an FAR of 1.5 would be 15,000 square feet (1395 square meters), an FAR of 2.0 would be 20,000 square feet (1860 square meters), and an FAR of 0.5 would be 5,000 square feet (465 square meters). in other parts of the industry. New York City is releasing data on its big buildings, never mind concerns about anonymity. Other major cities are taking similar steps.

You’ve also moved forward with the LEED Dynamic Plaque, a cool gadget that will show real-time LEED performance of a building to anyone who wants to see. The trouble is, the Dynamic Plaque is still a black box to most of us. What algorithms drive it? How long will it take for it to reach the majority of LEED buildings, and will it be a useful too both for individual building owners and for those of us looking at LEED’s overall performance?

Transparency rules

Photo – Paul BurkIt looks as if you don’t want to reveal any chinks in your armor. It’s a tough political and economic environment out there for LEED, and you rightly want to stay focused on transforming the market. We support you in that goal, but LEED is still accountable for its record. Transparency rules right now, and we want to know what has become of that MPR6 data. The release in 2012 was a red herring: it made sweeping statements about LEED buildings, and only in the fine print did we learn that it was based on a small sample of existing buildings, not representing a wide swath of LEED.

The latest release is potentially more exciting—data from almost 1,900 buildings, the largest release of LEED energy data yet, by far! Unfortunately, as I wrote in our reporting on this release, USGBC members are only getting a sliver of information out of it: an average metric from 450 buildings, and we don’t have the most basic information about size, type, and rating system. We’d also like to know how many buildings claimed exemptions.

Sure—we, like many others, know the difficulties in gathering good, reliable data and sharing that anonymously is not a trivial task. But with some of the energy you’re putting into the pretty but hard-to-navigate GBIG.org database, the new LEED Dynamic Plaque, or the rest of the finely produced content in the LEED In Motion reports, you can do better.

We need data on where we stand

Why? We want to know how LEED buildings are doing. LEED is a consensus policy built by USGBC's membership, and we deserve to see the results of that policy. We’re out there every day working on LEED projects and explaining LEED to clients and to the public. We’re making the case for moving beyond LEED 2009 to a new set of requirements without any data on where we stand now.

And it’s not just about LEED versus non-LEED buildings, even though that’s a debate that a lot of ink gets spilled on. More granular data can help attentive project teams see how buildings like theirs are doing, and improve on their work. USGBC, it’s time for a consistent, congruent approach to data. What’s good for LEED v4 projects as a prerequisite—and for building product manufacturers as demanded by designers—is good for USGBC and LEED.

Show us the data. Then, let’s continue to work on making LEED—and LEED buildings—better.

Sincerely,

P.S. My copresenters Rob Watson, Pamela Lippe, and I are looking forward to a great discussion on this and other LEED issues at the upcoming LEEDuser webcast—a reprise of our well-attended Greenbuild session—What Can We Learn from LEED's Critics? We hope you'll come!

I agree Tristan!

Perhaps we LEEDuser members can show our support of this concept through agreeing with Tristans open letter. This kind of information can help us understand what works and what does not. We just finished the second year of a very comprehensive M&V process, and even though the building is out performing the model, we are learning a lot about what our tools tell us, and what we can and cannot depend on.

Energy modeling is a tool that we use to make decisions, and we need to understand the limitations of any tool so we can then use it better the next time. I learned that in all my Habitat work!

Also, I attended the program Tristan mentions above, and it was extremely well done. There were great comments from the audiance captured using texts, and I hope that USGBC will take this feedback as constructive and informative critique. We all want the same thing, and feedback is an important aspect of learning in any context.

Minnesota's LEED certified building study

The Minnesota USGBC chapter evaluated the operational energy and water performance for all LEED certified buildings in our state.

You can find our report here:

This study is not "all" LEED buildings in the state, but 47%. Again with self selection occurring by those who do or do not want to submit the data can skew the results.

Hence Tristan's calls for USGBC to show data from 100% of LEED buildings. USGBC already has permission to access the data.

LEED Project Data Transparency

Interesting that there are more data details in my 2013 book, The World's Greenest Buildings:Promise vs Performance in Sustainable Design (Routledge), privately funded and researched, than there is from the $50 million USGBC organization. You are right to demand more details, so that independent researchers can use the data. For an organization that values "transparency," why is this taking so long?
