[Originally posted at EcoGeek. It’s not entirely new news, since the Army began adopting ASHRAE 189.1 in 2010, but it’s further movement in a direction they were already headed in. It’s probably a greater blow to LEED, since the DoD was one of its biggest adopters.
AIA Michigan COTE has been working to get more information about the new International Green Construction Code (IGCC) out to our members, and I have to admit that I’m still not completely clear about how the IGCC interacts with current state building code. I do think that there will be an increasing move toward having green building practice embedded in code.
At the same time, I think that LEED can maintain its leadership by further pushing the envelope. LEED has become very mainstream, and that is both good (in terms of overall uptake of the message) and bad (in that it has become less distinctive). LEED has to finesse the balance between being cutting edge and being accessible. I think, as it has become more and more popular, it has become too ordinary, and it needs to regain some of its distinctiveness and its status as marking truly exceptional buildings.]
[Edit to add: Some further clarification came out after I wrote this original article. See the followup posted at EcoGeek, as well, for a fuller picture of what is going on.]
While the headline may sound dire, it’s not an indication that the US Army is giving up on green building. Instead, the Army has announced it will use a new construction code of its own which is based on the ASHRAE 189.1 standard for new buildings and renovations, rather than continue to use LEED or the High Perfromance Sustainable Buildings standards. This new standard will “govern all new construction, major renovations and leased space acquisition.” The Army had already adopted ASHRAE 189.1 late in 2010.
Some of the impetus for this change is political. In 2011, Congress acted to prevent any Department of Defense project from achieving LEED gold or platinum certification as part of that year’s Defense Reauthorization bill.
Moreover, LEED is fundamentally a marketing program that recognizes buildings built to a particular high standard of performance. At its core, the Army is more concerned about having better buildings that it can operate more efficiently. Deputy Under Secretary of Defense Dr. Dorothy Robyn stated that, “With more than 300,000 buildings and 2.2 billion square feet of building space, DoD has a footprint three times that of Wal-Mart and six times that of GSA. Our corresponding energy bill is $4 billion annually.” The Defense Department recognizes the importance of green buildings for its overall operational effectiveness.
The armed forces have been one of the biggest early adopters of LEED, and if all of the services are going to move away from using LEED as their standard for improved performance, that is likely to have a strong effect on USGBC, GBCI, and the LEED program as a whole. “The repercussions of this announcement will be widespread,” notes Green Building Law Update. “For federal contractors, this is a game changer. The LEED AP credential will be less valuable. Past performance highlighting LEED certification will be less valuable, if not totally irrelevant.”
ASHRAE 189.1 is not some lesser standard. It was develeoped by ASHRAE (the professional organization of mechanical engineers), US Green Building Council, and IESNA (the professional organization of lighting engineers), as well as the International Code Council. Moreover, the Army’s action is not unprecedented. The International Code Council has also developed the International Green Construction Code (IGCC) which incorporates the ANSI/ASHRAE/USGBC/IES Standard 189.1 as a “jurisdictional compliance option.” Increasingly, building codes are going to directly incorporate green measures instead of relying on third-party standards that are merely optional.
Ultimately, this may push LEED in new directions. LEED was meant to push the envelope and to transform the marketplace. In that respect, it has accomplished much of that initial goal. As the industry has moved to embrace LEED, perhaps in the coming years, LEED will again push for even greater improvements in building technology and again make LEED an indication of a truly elite building.
