[Equest-users] GBCI comments on DCV (Carol Gardner)

[Dan Katzenberger]

Karen,

 

I am a voting member of the USGBC Energy and Atmosphere Technical Advisory
Group (EA-TAG) and I have been reading this discussion with great interest.
I think that the letter that you proposed in your other post is a good one.
I will e-mail you off-list with the requested contact information.

 

To summarize what I have taken away from this conversation:

 

-          The LEED EAc1 requirements for creating the baseline and proposed
energy models for projects implementing DCV are not clear and complete.

-          In absence of clear and complete modeling requirements GBCI has
required, for at least one project, that the baselilne ventilation rates be
set to the ASHRAE 62.1 minimum ventilation rates for the building in
compliance with EQp1: Minimum IAQ Performance.

-          There is interest by the energy modeling community in having
USGBC publish guidance for the correct modeling of DCV baseline and proposed
systems.

-          There are concerns about jurisdiction.  Does GBCI act as the
"rating authority" on LEED projects, and do they have the authority to set
requirements that are not specifically written or referenced by LEED
documentation?

 

Now that I am involved, guess who will likely be writing the first draft of
the DCV modeling guidelines if the TAG decides to move forward?  ;-)

 

Thank You,

 

Dan

Is anyone on this list-serve on the EA Credit 1 committee, or know someone
who is?  If the the GBCI or USGBC has changed the modeling requirements and
is only letting modelers know during the documentation review stage, I find
this very disturbing for a number of reasons.  It would be great if we can
get some straight answers on this from someone at one of these organizations
who actually knows what is going on.

 

I am happy to draft an email outlining concerns, but I don't know who to
send it to.  If anyone does, or would like to help me with this, please feel
free to contact me directly.

 

Thanks,
