[Bldg-sim] Cost of LEED certification

I think we're entering a whole new area of discussion rife with
controversy, but I can't help but throw in my two cents.
 
In terms of Marcus's last point, I think one of the quickest and easiest
ways to improve LEED in terms of delivering energy performance is to
split the M&V credit along commissioning lines and have a minimum level
of M&V mandatory as a prerequisite.  This way LEED would finally mandate
a move away from predicted energy use and begin to close the energy
loop.  Another idea is to make LEED EB certification a requirement for
LEED-NC buildings after say 5 years.  At a minimum, make
re-commissioning every 5 years an on-going credit.  As Straube pointed
out in the article I linked, operational energy is what's driving this
environmental train-wreck, but it's not what LEED or the design
community at large is focusing on unfortunately.  Nor is there any focus
to educate building owners and operators on how to properly run all
these "high-performance" buildings full of all this wonderful
technology.
 
Once M&V becomes a requirement, our community will need to educate
ourselves on how buildings actually work and begin the difficult task of
creating calibrated simulations that include all energy uses and account
for weather, occupancy and operation.

On your last point I agree whole-heartedly!

 

Without entering that data quagmire, I suggest that we all need to do a
better job of understanding building energy use, gathering more data,
connecting modeled and actual performance, developing better tools,
producing more informed modelers, creating performance feedback loops
for designers, developing better metrics, etc. to make sure LEED and
other systems produce the right signals and improve performance.

 

If anyone has any thoughts on how to improve LEED to ensure better
performance feel free to pitch in and help us make it better.

Marcus and all,

 

While the cost of LEED Certification is important, equally important are
how well are LEED projects performing. The New Buildings Institute study
(March 2008) of 121 LEED NC v2 buildings certified through 2006 claimed
"on average LEED energy use 25-30% better than the National Average."
However a number of critics of this study has emerged, many of whom used
the same data that NBI used. Henry Gifford has question the methodology
used in the NBI study. The American Physical Society in their Energy
Future: Think Efficiency Report as well as Joe Lstiburek has also
questioned the NBI study. Now Dr. John Scofield from Oberlin has
completed a detailed re-examination of the NBI study and has found that
"the NBI data shows that LEED certification has done nothing to lower
building primary energy consumption and associated GHG emission." I have
attached his paper which will be presented at the International Energy
Program Evaluation Conference scheduled for Portland, OR. August 11-14,
2009. 

 

I believe that the Bldg-Sim community needs to address this issue.
Otherwise the services that we perform will become seriously questioned
by the building profession. Even if LEED buildings cost more, which I
believe most building professionals and clients would accept. It is
unacceptable if they can't deliver on energy performance. 

 

Regards

Paul without seeing the articles to which you refer I really can't
comment about the comparison of the studies.  

 

Regarding cost and LEED I can offer my own personal experience on more
than 100 commercial projects pursuing LEED certification - none has even
come close to approaching the bottom end of the cost range in the ACC
study.  I have no doubt that some projects are spending 4.5% to 11% more
but frankly they are using LEED the wrong way (as a checklist of
independent variables in a point hunting exercise) and the market will
weed those practitioners out over time.  All things being equal LEED
does add cost but it is only the measuring tool.  The real question is
does a high performance green building cost more?  If done correctly my
experience is that it does not.

 

We are currently working on a school project which is borderline
Platinum.  It was bid last summer and came in significantly under budget
and attracted a $500,000 state grant.  So the actual cost is less than
conventional overall even without the grant.  Project cost drivers are
primarily a function of building type and location.  Within those broad
categories it is about design choices, one can choose to focus resources
on building performance or on other priorities.  Project teams who
choose to focus on the priorities spelled out in LEED can easily do so
within the confines of a conventional project budget.  The rest is just
a bit of paperwork.

 

The first time that an architectural firm had to use CAD drawings
instead of hand-drawn; the first time they had to comply with ADA; when
major building code changes occur - all of these things resulted in
added costs.  As experience is gained costs come down significantly and
the same thing is happening with LEED (the ACC study indicates that this
was likely to happen).

 

The real answer to your question is - "it depends" - on many factors
including team experience, priorities, project size, strategies, design
process, etc.  You really can't assume it costs more but if you do, it
probably will.

Thanks for the links Marcus.  

 

I have scanned the Langdon document and even looked at later articles
written on the topic.  They agree that the Langdon study is more
comprehensive but still gravitate towards the costing provided by the
American Chemistry Council. My take on the matter is that the real issue
here is not whether LEED certification costs more, but how much does it
cost: both in terms of time and expense.

Anyone's first LEED project requires an investment of time to learn how
to do it.  This learning curve is somewhat steep but once you learn how
to do, actually doing it takes considerably less time.  Outside soft
costs (commissioning, energy modeling and LEED documentation) if you are
spending a dime more for construction costs than conventional for LEED
Certified or Silver then you have made an optional choice or are not
properly applying the system.  Many projects attain the Gold
certification level without an increase in construction costs.  

 

There have been several cost studies over the years than do not show
that LEED requires the type of investment purported by the American
Chemistry Council.  Here are some links:

 

http://www.cap-e.com/publications/default.cfm

http://www.davislangdon.com/USA/Research/ResearchFinder/2007-The-Cost-of
-Green-Revisited/

 

The Davis Langdon study above is far more thorough and comprehensive
than the much older ACC report which relies on a considerable amount of
early anecdotal evidence.

 

In many respects the cost of LEED comes down to what you assign to LEED
as an "extra" cost.  Many teams have figured out how to neutralize even
the added soft costs through an integrative design process.

I recall someone once asked about the time needed to be spent on LEED
certification.  Well, I have just come across a report prepared by
Northbridge Environmental Management Consultants
<http://www.nbenvironmental.com> entitled Analyzing the Cost of
obtaining LEED Certification, which is available online at the following
link: 

 

http://www.cleanair-coolplanet.org/for_communities/LEED_links/Analyzingt
heCostofLEED.pdf

 

It indicates that the documentation takes 226 working hours on average
to prepare and costs between US$8,000 - US$70,000 per project: the first
project costing between US$30,000 - US$60,000.
