Who is this for: Architects,
engineers, and other building professionals performing energy analyses who want
to understand the relationship between Autodesk Revit®, Autodesk Vasari®, and Green Building Studio®, and
get an overview of the Green Building Studio features.

In this post we are sharing a new video that
provides a quick overview of the whole building energy simulation workflows
that are available in Autodesk tools. Hopefully this video helps you to know
more about what’s behind these energy analysis tools and to choose the
appropriate tool that fits your job.

 

The integration of Green Building Studio with Revit
and Vasari provides a seamless workflow from model creation to energy simulation,
without needing to leave the authoring environment. GBS uses the DOE-2 simulation engine for calculating the hourly, whole building energy
usage of your project.

Energy and Carbon Analysis can be performed in
many different ways using these tools. A previous post on this blog by Marjorie
Stein explains GBS workflows with a bit more detail than the video above. See: Autodesk Green
Building Studio—the Power Behind Autodesk Energy Analysis Features
.

You can use schematic mass models as well as
more detailed models to send simulation runs to GBS. You can also use gbXML
files exported by Revit, Vasari, or third party authoring tools to perform
energy simulation using GBS. When you export a gbXML file from Revit or Vasari, it does not contain as much information as models that are simulated using the built-in energy simulation tools. The built-in simulation tools apply more parameters to the model based on the "Energy Settings" dialogue box.

You can use “Results & Compare” dialog to view
energy analysis results within the same environment or access more detail
results within the Green Building Studio website.

After performing energy simulation in Green Building Studio your model and results can be exported in several formats that can be used by other energy analysis tools. You can export as DOE2, gbXML, or Energy Plus file formats. These files will contain the energy simulation results from GBS, as well as the values for any missing data for energy simulation that GBS has applied to your model. 

Your feedback is important to us!  Have
you used the energy analysis features in Revit 2014, Vasari or Green Building
Studio? Is this video helpful? What do you think about adopting these
workflows?
