Another good venue for this discussion/seminar would be the US Green
Building Council Conference - GreenBuild in Pittsburgh this
November. Will be a great mix of the players - architects,
engineers, contractors, owners, etc. If anyone is interested I can
put you in touch with the organizers. <br>

<blockquote type=cite class=cite cite>I've found this discussion of 3D
Modeling + Energy Analysis, or getting<br>
the whole design team into the performance assessment game, most<br>
fascinating. I would like to propose a seminar, or series of
seminars<br>
and symposiums (documented case studies) on the topic, or various
topics<br>
presented in the preceding chain.<br>
I know this isn't necessarily original but to see it discussed on
this<br>
particular forum adds, I think, a new dimension. I'm pleasantly<br>
surprised at the number of responses from architects who, by their<br>
presence on BLDG-SIM@ Gard.com obviously pay attention to modeling
and<br>
building simulation. <br>
They could start within a group such as ASHRAE, but would need to
branch<br>
out to AIA and other associations. Ideally, we could produce
something<br>
to present at local venues, to the local design, owner, operator<br>
community. <br>
There is time to probably get a seminar at the ASHRAE Winter meeting
in<br>
Anaheim, Jan 04. I can think of at least two ASHRAE Technical
Committees<br>
that would be interested. <br>
Anyone interested? Other venues?<br>

<br>
I may point out that we have started some work at IIT Bombay in<br>
association with architects for combining building design and<br>
simulation. The architect does not have to know the details of a<br>
simulation. We have integrated the design and simulation process.
The<br>
first part of the project has been completed. It is called
TADSIM:Tools<br>
for Architectural Design and SIMluation. A part of the result was<br>
presented in SOLAR 2002 (Reno, Nevada, USA) in June 2002.<br>
<br>
Thanks.<br>
