GeoPraxis Publishes First XML Schema for Building Energy and Environmental
Performance Analysis
Open “Green Building XML” Schema Now Available

SONOMA, CA --(BUSINESS WIRE)-- June 2, 2000 -- Keeping to a schedule set
last month, GeoPraxis, Inc., the leading provider of XML-based energy and
environmental analysis software today published an open XML schema that will
greatly facilitate the analysis of building energy and environmental
performance by architects, engineers, and others who design and build

The new schema, Green Building XML (gbXML), will facilitate the transfer of
building product characteristics and equipment performance data between
manufacturer’s databases, CAD applications, and energy simulation engines.
The gbXML schema is poised to become the interoperability standard for
sharing data between programs of this type.  Improved data interoperability
between the desktop and web-based tools currently used in the architecture,
engineering, and construction (A/E/C) industry will greatly reduce the time
and cost of designing high performance, energy and resource efficient

John Kennedy, Principal and head of software development at GeoPraxis, said,
“After public review by 45 representatives from industry, research, and
media organizations, V1.0 of the schema has been completed and submitted to
the BizTalk and IAI/aecXML organizations.  We are thankful for the many
comments and words of encouragement we received during the review process
and look forward to working with many of these parties to make the vision of
truly useful building performance analysis tools become a reality.”

Mr. Kennedy has been invited to discuss the schema and demonstrate it in
action at three upcoming venues: a workshop at Lawrence Berkeley National
Laboratory (June 16), the International Alliance for Interoperability’s
aecXML/IFC meeting held in conjunction with the Construction Specifications
Institute annual convention in Atlanta  (June 23), and the International
Building Performance Simulation Association (IBPSA) semiannual meeting in
Minneapolis (June 24).

“Building performance analysis is a hot topic right now and gbXML appears to
be the best way to get powerful building performance simulation capabilities
into the hands of new users as quickly as possible", said Duane Barrett,
Product Manager, HVAC Applications at Bentley Systems, Incorporated.

GbXML V1.0 is fully compatible with the most recent revisions of the aecXML
guidelines and the BizTalk framework.  Developers and others who wish to
download the schema may do so immediately via www.BizTalk.org or visit
