The U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Version 4 (V4) has been approved and will be become official at the Greenbuild International Conference and Expo in November 2013. But even after the new version comes out in November, you can register and begin LEED 2009 projects up until the summer of 2015. This means that for the next two years we will have LEED 2009 projects coexisting beside LEED V4 projects.
These programs are very different especially with regard to transparency issues. For example, Health Product Declarations (HPD’s), Environmental Product Declarations (EPD’s) and Life Cycle Assessments (LCA’s) are moved in V4 from where they were in LEED 2009. In LEED 2009 they are classified as pilot libraries but now have been moved to materials and resources, credits two, three, and four. This represents a significant change to the materials and resources credits.
The co-existence of two different programs could, potentially, cloud the issues for the end users. But making incremental steps can help to keep people focused on a sustainable future without feeling that they have to start all over. But does the potential exist for the momentum of LEED to stall because we are not looking far enough into the future?
Consider the Living Building Challenge which is the gold standard for what some advocates envision for the sustainable future. Have they thrown the target so far down the field that it doesn’t need to be continually updated because the goals are not highly achievable today? It sets the bar very high but it does give us a long range goal for future development.
If you want to change the future you can’t do it based upon the past. Psychologists tell us that our default reaction to a challenge is based on our experience and history. When presented with a situation we tend to lean on the past. This causes us to repeat the past and impedes our ability to get to a desired better future.
If you want to get to a future that is different than the past, you have to imagine a future not based on the past. You have to set your target not based on incremental changes because that just builds on the past. Let’s start by saying “in 10 years, I want to be over there”- now work back from there until now and NOT forward from now until then. I think you’ll find that you end up much closer to where you want to be this new way than you did with the old way.
I, for one, would not want to see our efforts to move toward energy efficient, sustainable buildings stalled or worse, abandoned, because we failed to see a clear path to that future. If we get too caught up in the process, we could lose sight of the purpose.
