Fundamentals and Applications
Chair:
Stephen Roth, P.E., Carmel Software Corp.
Technical Committee: 01.05 Computer Applications
CoSponsor: MTG.BIM Building Information Modeling
This seminar discusses how Building Information Modeling (BIM) tools are changing the way engineers perform HVAC system design including duct design, hot and cold water piping design, plumbing and fabrication. One speaker discusses how BIM authoring tools are helping to: Coordinate duct design, calculate duct/piping pressure drop, perform design validation and more. A second speaker discusses how conceptual HVAC design schematic tools work with BIM authoring tools. A third speaker discusses how these various tools from different vendors are able to communicate with one another using open source interoperability languages.
1 BIM Software and HVAC System Design
 |
Martin Schmid, P.E., Autodesk |
Martin discusses how BIM authoring tools perform the following: Coordinating duct design, sizing calculations, pressure drop calculations, design validation – visualize areas of high velocity / pressure drop and pressure loss reporting. Martin uses an example from the ASHRAE Handbook of Fundamentals that will show near apples-to-apples comparison of the results from the BIM software vs. the results from hand calcs.
2 HVAC Schematic System Design
 |
Joe Simmons, P.E., HVAC Solution |
Joe discusses software used for schematic modeling of HVAC systems and why it is so important for initial conceptual design. Such tools are important for automatically modeling simple and complex air, hydronic and steam systems in new or existing buildings. They are also used to calculate ASHRAE 62.1 loads. Through use of interop schemas like gbXML, HVAC schematic tools can import HVAC load information and export HVAC system information to and from BIM authoring and analysis software tools.
3 Sharing Information between BIM and HVAC Design Software Tools

Stephen Roth, P.E., Carmel Software Corp. |
Stephen gives an overview of various interoperability schemes like the open-source Green Building XML that allow building information modeling (BIM) authoring tools to transfer information to HVAC analysis tools. As BIM becomes more accepted, it is vital that information be shared between various HVAC design tools. For example, HVAC engineers are able to extract the mechanical and building property information to perform duct and pipe design, and HVAC load calculations. As software becomes more available in the "cloud", interoperability schemas become much more important since information needs to be transferred in a structured format from mobile and desktop devices.
