This topic was brought up a few days ago from @MikeSealander. He was looking for some verification that the process of going from a Revit model to the DOE’s EnergyPlus analysis software was possible using Ecotect as a go between. While I have had some success with this process it was always using Green Building Studio as the intermediate tool.
Seeing as EnergyPlus is the most sophisticated energy analysis tool available and Revit is now become some what of a standard for the AEC industry it seemed like a natural fit. So I went ahead and gave it a try.
The long short if you have no interest in watching the videos is that I was impressed with the amount of detail and the level at which the geometric and construction information was brought across into EnergyPlus. While I ultimately believe that analytical energy models should be kept separate from Architectural models, if you prefer to have some sort of link, dynamic or not, this is definitely a workable method.
The 7 Easy Steps to Success are:
Create Analytical Spaces in Revit
Modify Room Bounding Objects
Verify Analytical Volumes
Export GBXML
Import GBXML to Ecotect
Export IDF to Energyplus
Verify in Geometry and Constructions in OpenStudio/IDF Editor
If you want to follow along with me here are the requirements:
My presentation for the February 2012 NYC Revit Users Group is up! Special thank you to Robert Mencarini and James Vandezande for allowing me to speak that night. Enjoy! credit: NYCRUG http://www.meetup.com/NYC-RUG/boards/view/viewthread?thread=20890942
My recent posts have been more Revit focus, taking a short break from the energy analysis side of things. I posted Part I and Part II on some issues that companies have that relate to graphical standards and content. This types of issues seem to be at the forefront of BIM implementations within MEP firms and unfortunately they cloud the true benefits of a BIM platform which is the management of information, such as in the form of Schedules and calculations. You would be surprised how many MEP firms I talk with still have not implemented standardized schedules. With that being said I wanted to focus on a recent problem I was attempting to solve relating to mechanical elements adapting to the environment they are in. With the benefits of System in the Revit MEP platform you can manage connectivity of elements for the purpose of Scheduling, flow calculations, pressure drop calculations etc. The unfortunate aspect of this is that much of the input is done by hand. Realizing that in most cases the input information is already prevalent in the model I wanted to tackle the simple task of transferring calculated space loads to the space terminal elements (ie. air terminals and terminal boxes) for the following purposes (simplified list of course as the trickle down effects would make for a … Continue reading →
You can follow the same procedure for DesignBuilder as well. You can use full functional 30-days evaluation copy for this purpose. # Create Analytical Spaces in Revit # Modify Room Bounding Objects # Verify Analytical Volumes # Export GBXML # Import GBXML to DesignBuilder # Export IDF to Energyplus
Thanks for this value information, I´m working on with this two ways, EP and DB, but what I like more is that EP plug-in is for free with open studio. I have the SK licence so is more powerfull with EP.
Best regards from Chile.
Thanks again.

yes, i prefer to use sketchup and openstudio myself. it is a great way to create geometry and it provides a clean IDF file to work with. they have also incorporated the templates and basic features of the IDFeditor and EP-Launch. i understand other interfaces similar to openstudio are in the pipeline. looking forward to comparing features.
