[bldg-sim] Call for participation in the HVAC implementers' round table

[Vladimir Bazjanac]

I apologize for multiple postings of this message.  Essentially the same
message was sent to a number of different exploders.

As you may know, IFC HVAC definitions have been extended to support
exchange among design and simulation applications.  The integration of
the HVAC extension schemata with the IFC core model is in progress right
now; the new version of the IFC data model (IFC2x2) that will include
these extensions will be released in May 2003.  Software implementation
of the new IFC2x2 model (based on the beta release) can start in three
months from now.  LBNL plans to follow that schedule and develop a
comprehensive IFC2x2 interface to EnergyPlus that will implement the new
IFC HVAC definitions.

The extended IFC HVAC model includes more than most HVAC and/or related
applications need to implement individually.  HVAC and related
developers need to agree which definitions need to implemented by *all*
implementations, and which need not be implemented.  In addition, they
need to agree how to commonly implement definitions that need to be
implemented.  In other words, there is a need to formulate implementers'
agreements for HVAC applications, similar to what IAI CAD developers did
for CAD implementations a few years ago.

HVAC implementers' agreements should provide the basis for HVAC data
exchange among more than just HVAC applications.  Critical application
developers from other related industry disciplines that also use HVAC
data (such as cost estimating, CAD, construction management, project
management and facilities management) should also participate in the
forging of HVAC implementers' agreements.

LBNL is organizing an HVAC developers' "round table" at LBNL offices in
Washington, DC on Friday, December 13.  HVAC related software developers
are also invited to this round table.  If West Coast developers cannot
travel to Washington, DC they can join a telecast of that meeting at
LBNL offices in Berkeley.  Alternatively, a limited number of phone
links to the meeting will be available free of charge for those who
cannot attend at either LBNL location.  The meeting will start promptly
at 11:00 EST and end at 14:00 EST.  Follow-up meetings, teleconferences,
and/or video conferences will be subsequently scheduled as needed.
Please let me know if, and at which site, you can attend this meeting.

You can download the new IFC HVAC extensions schemata for IFC2x2 from
the BS-8 project web site.  The URL is
http://iaiweb.lbl.gov/bs8/documents/BS-8_Model/; from there download
file BS8HtmlDocumentation_15Jun02.zip, unzip it and save extracted files
on your system, open with your browser any *.html file you just saved,
and then navigate as needed.  I will send more information and files to
those who notify me that they plan to attend the meeting prior to the
meeting.
