Performing a Heating and Cooling Loads Analysis

Heating and cooling loads analysis determines the heating and cooling demands of the building model. After spaces have been placed in all areas of the building model and zones have been created, and you have prepared the project for heating and cooling loads analysis, you can perform heating and cooling loads analysis using the following methods:

• Use the integrated tool within Revit to calculate loads and create a report.
• Export the project information to create a gbXML (Green Building XML) file. This method opens the Export gbXML dialog, which provides the same tools as those found in the Heating and Cooling Loads dialog, except that instead of calculating loads and producing a report, it allows exporting the heating and cooling information to a gbXML file.

  The gbXML file contains all of the heating and cooling information including spaces and zones for a project. You can  then import the gbXML file to a third-party load analysis software application that will perform a heating and cooling loads analysis.

  The gbXML open schema was created to help building designers get information about the energy consumption characteristics of their building projects. For more information about the gbXML schema, see gbXML at http://www.gbxml.org.
