		<description><![CDATA[Announcement from gbXML.org: gbXML Webinar: &#8220;How gbXML Works with New Building Performance Software from Autodesk and Bentley&#8221; May 23, 2012 from 2:00 pm to 3:00 pm EST – Live Webinar We are holding our semi-annual gbXML webinar on May 23rd, 2012 at 2:00 pm EST. This webinar will demonstrate the integration of building energy performance and BIM software by using the interoperability capabilities of gbXML. This is all in the name of designing more energy efficient buildings. Presentations and product demos will include the following: Matt Jezyk will demonstrate Autodesk® Vasari® Dru Crawley will demonstrate Bentley® AECOsim Stephen Roth, President of the gbXML.org and Principal of Carmel Software will also discuss the current status of the gbXML and related activities.

		<description><![CDATA[Hi everyone, my name is Neil Bulger and I am an energy modeler for a small design MP firm on the west coast in Oakland, CA. I&#8217;m happy to join the writing team here on the openRevit site. My focus and interest in energy modeling has been to find open-source tools that can both mold to the job required and providing enough information under the hood for engineers and owners to feel comfortable with the results. Today, I&#8217;d like to share a neat tool I found a while back called Greenspaceslive (greenspacelive.com). The tool is a plugin that works with Google Sketchup and allows a 3D model of a building to be tagged with surface types and assigned to spaces, building a gbXML file that can then be exported to a number of various software tools, such as Trane Trace or in California, EnergyPro used for code compliance. While this is a free tool that can create gbXML, which is fantastic, it is not without its holes, and it has some major ones. I honestly think this is a great tool, but for purposes of today, I will talk about the shortcomings and some advice. The way the program works &#8230; <a href="http://openrevit.com/2011/08/green-spaces-live-free-gbxml-tool/">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>

		<description><![CDATA[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&#8217;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. &#160; 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. &#160; 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&#160;ultimately&#160;&#160;believe&#160;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. &#160; 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 &#8230; <a href="http://openrevit.com/2009/12/export-revit-to-energyplus-via-ecotect/">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
