building design, and the documentation to obtain the desired design
certification. The solution to this dilemma is to export your Revit MEP
model via Green Building XML (gbXML) format to a third-party simulation
program, such as Trane TRACE 700 or Carrier's HAP.
gbXML was developed in the late 1990s to enable interoperability between
building design models and engineering analysis tools. Its use by major
CAD vendors and several major engineering simulation vendors helps to
streamline time-consuming building takeoffs—helping to remove some of
the cost associated with the design of energy-efficient buildings. Go to
http://gbxml.org
for more details on the purpose and origin of gbXML.
To export your Revit MEP model, click the Application Menu button and
then choose Export gbXML. You will be directed to the Export gbXML
dialog box, shown in
Figure 8.29
.
Even though the architectural model is
linked into your project, the geometry will be exported to your analysis
program.

Export gbXML dialog box
This window looks nearly identical to the Heating And Cooling Loads dialog
box (shown earlier in
Figure 8.14
)
. If a heating and cooling load analysis has
already been performed, the majority of the parameters in the General tab
should already be defined per your design requirements. If not, adjust the
parameter values as needed; these parameters were discussed earlier in this
chapter.
