@Amorphous - Julian You would have to map the data to IFC first - in 2019 you would go to AEC>IFC data mapping and for Wall object (left pane) map to an IFC pset. You can add IFC entities/data sets (middle pane), for example Material, expand so you see data field as Component 1 type STRING, then define mapping (right pane) as Component Thickness.

Hi all,
This is a very interesting topic and one I've been involved with increasingly. As a starting point, I'd like to say we will be doing a Service Select Webinar on Energos this Friday the 13th at 2.30pm. See description below:
Climate change and sustainable design is at the forefront of today's conversation. Integrated design tools can help you be more efficient and make quicker decision during the design phases.
During the webinar attendees will learn how to assess the energy performance for a building design very early on in an integrated design process using regular evaluations during the design process. This will give the Architects, the power of being able to make informed design decisions and some metrics to back those decisions up regarding sustainable and energy efficient design.
Learning Objectives:
Discover the benefits of integrating energy performance evaluation into architectural design workflow
Explore how building's form factor and shape affects it’s energy performance
Learn how various opening shading percentages and different types of shading can guide your design decision based on the expected building performance
Evaluate energy performance changes based on building elements boundary conditions and U-values
If you are interested in Energos I would definitely recommend joining in, for anyone outside UK we will be doing a repeat for US in spring, probably around May.

Yes, very useful and accurate, but of course the accuracy will depend on the input you provide to the plug in. I find it very useful in architectural design workflow as a tool that helps you track the performance of your building throughout the design process, from early stages to technical design. I will talk about this process in the webinar.

It's one of the things we are trying to address as well, particularly in the current climate (pun intended) and particularly as we have the tools that Architects need to design sustainable and energy efficient architecture.
On 3/5/2020 at 10:54 AM, Asemblance said:3- As above, but for linking Specification of materials to Vectorworks models
Are you referring to an NBS spec here? With Vectorworks 2020 SP3 it will be possible to integrate models directly with NBS Chorus and objects with spec clauses.
On 3/5/2020 at 10:54 AM, Asemblance said:Is there any plug-in, module, or functionality, which would help us to calculate embodied carbon in our Vectorworks models?
On the Embodied Carbon front, we have looked into this and we have developed a workflow to calculate embodied carbon, based on the ICE database from University of Bath so something similar to what H/B:ERT does, only not in the form of a plug in as of yet. We have things in the pipeline that will enable users to calculate Embodied Carbon in a much easier way.

@Amorphous - Julian Just to clarify, you can report the core thickness in 2019, but the total wall thickness and sequential reporting of individual components is added in 2020.
4 hours ago, Amorphous - Julian said:I suppose sequence is counting from the top of the list, correct?
Correct.

@rDesign I'm not aware of a setting which allows you to display both U-values and R-values simultaneously, but I'm UK based and only ever used U-values really so the option works fine for me. I might be missing a trick here but I will check with our team in the US and report back. As someone in the thread mentioned, the relationship between them is inversely proportional, so if your Units are set to R-values you could have a small window U-value conversion worksheet to display 1/R-value. I understand it's a workaround but I'll let you know if it's possible to do it on an object by object basis.
1 hour ago, rDesign said:As there are currently no Energos workflow training webinars available on either the U.S. VSS portal or Vw University, having access to this UK-focused one would be much appreciated
We are doing a webinar for our US customers in May, it will be announced soon. I'll post a link to register in this thread when we have a date. @Luc Lefebvre what's your view on this?

Hi Julian,
Wall thickness is reported through Object Function - Wall Thickness - #WALLTHICK#
If you wanted to report the thickness of the core, the easiest is to define mapping to IFC pset (Material ie) as Component Thickness - [Component.Thickness]. This will report only the thickness of the core component.
If you wanted the thickness of each component, you can create a custom IFC pset and use Expert Formula GETCOMPONENTINFO(n,4) where n is the sequence number of the component. Then you can define the Data Tag field with data source from your custom pset.
Hope this makes sense!

Hi All,
On 3/5/2020 at 6:17 PM, rDesign said:has the problem reported in this thread (way back in 2016) been addressed?
U-Value or R-Value is set as a document unit via File/Document Settings/Units/Energos, with additional option to switch to Imperial, which will display R-Values in sq ft F h/Btu.
On 3/7/2020 at 2:15 PM, line-weight said:Does anyone actually, successfully use Energos for "real"?
Absolutely, there are a number of companies and individuals using Energos in various workflows - from early stage design evaluation to complex accurate calculations to then be exported to PHPP

Data Tag- How to Report Thickness of Wall
in Troubleshooting

Then the next step is to set up the Data Tag to obtain value from #IfcWallStandardCase#.#Material#.#Component 1# (the first part of this formula is IfcEntity, second is pSet and third is Property name. IfcEntity will depend on where you insert the Material pSet, in this case I've put it under IfcWallStandardCase)
