How to Make Your CAD Data Do Five Times as Much Work at No Extra Cost

The Lawrence Berkeley National Laboratory, in cooperation with Southern
California Edison (in an event in Santa Monica) and Pacific Gas and
Electric (in an event in San Francisco), will demonstrate the exchange
of architectural and engineering information among various software
applications using IAI's IFC R2.0.  This is a "reality breakthrough;"
after almost six years of developing interoperable standards, the
Alliance is pleased to show that commercial software developers are
delivering products incorporating IAI's IFC standards that will
dramatically change the way professional designers, building owners and
managers, and a host of other AEC+FM professionals will work in the
future.  Commercial vendors such as Timberline Software Corporation,
Microsoft Corporation, and others, will exchange CAD drawings, cost
estimating information, engineering data for energy analysis, and more
at both events.  The attached file provides more background and detail
about what will be shown at the events.

The event in Santa Monica will take place at the Southern California
Edison's Customer Technology Application Center (CTAC), 1721 22nd St.,
Santa Monica, CA 90404, phone (626) 812-7537 or (800) 336-2822, on
Tuesday, February 20 9:00-noon.  The event in San Francisco will take
place the next day (Wednesday, February 21) at the Pacific Gas &
Electric's Pacific Energy Center (PEC), 851 Howard Street, San
Francisco, California 94103, phone (415) 973-7268, also 9:00-noon. 
Please announce these events to your staff.  Those planning to attend
either event should register at the IAI NA web site:

<p class=MsoBodyText style='text-indent:.25in'>There is now a better solution

years by a non-profit organization known as the International Alliance for

this change will improve the practice in your office in years to come.</p>

<p class=MsoBodyText style='text-indent:.25in'>A group of well known software
developers for the building industry formed the Building Lifecycle
Interoperable Software (BLIS) project and has developed commercial grade
software that can seamlessly exchange IFC-based data developed in CAD
applications for use in cost estimating, thermal analysis, mechanical design,
construction planning and other industry processes. The BLIS group (Fig. 1)
includes industry software leaders such as Microsoft, Graphisoft and

<p class=MsoBodyText style='text-indent:.25in'>It is now possible to take a
standard two-dimensional CAD drawing (floor plan), define the third dimension,
objectify it (i.e., define its content as ?objects?) and save it in the
interoperable format.<span style="mso-spacerun: yes">? </span>Or, one can
define the building in three dimensions using object oriented CAD software and
save it directly in the interoperable format.<span style="mso-spacerun: yes">?
</span>Software that performs quantity take-off can then use the saved
information and generate lists of quantities for use by cost estimating
applications.<span style="mso-spacerun: yes">? </span>Or, the saved information
can be used to automatically check prescriptive compliance with energy
codes.<span style="mso-spacerun: yes">? </span>Or, the saved information can be
seamlessly imported into EnergyPlus (a ?new generation? simulation tool) for
the simulation of the building?s energy performance.<span style="mso-spacerun:

needed to prepare the building description for such an energy performance
