Industry Foundation Classes (IFC):
Development of HVAC Interoperability Standards for Computer Assisted Design
Goal Statement:
To extend Industrial Foundation Classes (IFC) schemata to support the modeling and simulation of heating, ventilation, and air
conditioning (HVAC) components and systems in various IFC-compatible building simulation tools (such as EnergyPlus). This extension
will facilitate the seamless importing of information from upstream applications and databases (such as general definitions and
performance specifications of HVAC equipment and furnishings). It will also facilitate the seamless exporting of generated information
to downstream tools, such as facilities management tools.
Results:
- Formal collaboration was established with other national and international organizations and institutions:
- An international project kick-off meeting was held at LBNL
- Interoperability workshops were organized by California utilities (in Santa Monica and San Francisco)
- A project website was created for public and private access

The IFC modeling work has been accelerated and as such was completed during the second year. This included the definition of all
needed object/attribute/relationship sets and coding in the EXPRESS modeling language of all the IFC extension schemata. It also
included the development of the EnergyPlus Client for the BS Pro COM Server. This has allowed us to pursue market connections with
software implementors one year earlier than originally planned.
