  1. @Kazemester Hard to say what's going wrong without seeing the files. One thing that comes to mind is that mapping in Data Manager is for Class based objects, so when you create Extrudes using Modify by Record they will be created on active Class. If that is not the same as the Class you mapped data to, it won't work. If it still doesn't come through, try mapping in the Data Manager after you've extruded the Polygons making sure the objects are on correct classes, perhaps that will do the trick. Let me know if you manage to do it. Good luck!
  2. @Kazemester sorry about late response. See the attached video - is that what you are looking for? Hope it helps and the video is clear. Let me know if you have further problems in getting the Ifc data across. Screen Recording_Mapping Record Format data to custom Ifc pset.mov
  3. Hi @Samuel Derenboim I agree that you could run these calculations in worksheets too, however this would be a very manual process and would require a lot of setting up by someone who knows the subject very well. Benefit of having a tool like Energos is it becomes an automated and streamlined process that can be used by Architect who are not necessarily experts in setting up the formulas themselves. I think you're looking at the wrong place here. I wouldn't try to extract these values from Energos, I would use worksheets. Output of Energos is things like Heating loads, Energy demands, Overheating etc. Sure, it uses things like Exterior/Interior wall surface area to get to those outputs, but they are a means to a different end. It's not a limitation, even more so as you can get those surface areas in a report. WALLAREA_GROSS and COMPONENTAREA(n) will give different results because the first one will give the area of the wall based on the wall centerline and wall height, and the other will display the surface area for Component n. In an example of a 300mm thick, 10m long, 3m tall wall with two corner joins with other 300mm walls WALLAREA_GROSS will be 29.1m2 but the COMPONENTAREA for outer component (red in image below) is 30m2 WALLAREA_NET will instead return WALLAREA_GROSS minus any recesses or openings. I will be looking more into wall surface areas and how they are calculated in Vectorworks and in Energos, including corner windows, curtain walls and There are a number of functions which you can use to extract different quantities using Worksheets, it's a matter of choosing a right one to get to the corrrect numbers! Hope this helps and clarifies the issue.
  4. You can exclude individual Spaces by unticking Use in Edit Spaces List. This will update the Total Relevant Floor Area
  5. Edit curtain wall style insertion options tab has Include in Energos Calculations greyed out. This is because Energos settings are located under Frame and Panel settings and type of frame and glazing can be set from a customisable list with parameters. Thing to bear in mind is that for frames this needs to be set for vertical, horizontal and all boundary frames individually.
  6. Hi everyone, Bit late to the party, but I'll try to chime in and add to the conversation. I'll also reply to some of the queries raised previously in separate posts, but it might take me a while to go through the thread. My general view is that Energos is a fantastic tool for Architects to understand the energy performance of their design and to do so throughout the design process. I feel sometimes users expect it to be something that it’s not - energy modelling software. Vectorworks is, as you know, a Design Software (in this case we're talking about Architectural Design) and Energos has been developed as a supplement to an Architects' workflow, not as a replacement for the likes of IES. It's based on mathematical calculations using PassivHaus methods - this is what enables it to update the results and recalculate in a matter of seconds instead of much longer times that would have been required if it were modelling the solar path and geometry to calculate shading for example. Instead, it relies on Designers' manual input to determine shading percentages for each opening, which requires either a manual detailed calculation in order to input an accurate percentage value or leads to some minor inaccuracy. To summarise, I think if accepted for what it is, a very useful and in-depth energy performance evaluation tool to accompany your architectural design process from the very beginning, then it has a real value to Architects and gives them power to make informed design decisions at every step in that process do they can create truly sustainable and energy efficient architecture.
  7. @Kazemester I've just tested the workflow as I described above and it works for me... Can you send me the file with 2D polygons that have Record Formats attached to them?
  8. @Kazemester When you map the data from a Record Format to a custom Ifc pSet, you should be seeing actual values from the individual object, not the defaults from the Record Format
  9. Next step would be to use the Data Manager to map the data from the Record Format to Ifc psets - the key here would be to have all of these Extrudes on the same class. Then you can use the Class-based objects in the left pane of the Data Manager - add the class that the Extrudes are on, then in the middle pane add the Ifc Data Set you wish. Final step is to define Data Mapping for the Data Fields in the Ifc Data Set and link those with Simple Formula using Initial Field value as Record Format and then select the field you want to map to. I hope this makes sense, but let me know if it works or not and I can try to explain better if needed. Good luck!
  10. @Kazemester I'm trying to understand how are you extruding the 2D Polygons? If you are using the Model > Extrude command it will essentially create a new Extrude object. If you edit the Extrude you will see the 2D Polygon with the Record still attached to it, that's the reason that the Extrude does not inherit the Record Format. If you follow what Tamsin has suggested, and use Modify by Record command, the Record format will be preserved and it will be attached to the Extrude object. I suggest creating a dummy field in the Record Format which you would populate by the extrusion height and use that field for Modify by Record.
  11. Hi @KIvanov Thanks for the update and for the fix. Hope this solves the issues and enables the users to tag smoothly while using project sharing.
  12. @Amorphous - Julian I'm not sure when the fix will be available, I will check with the engineers. I will add your comments to the bug report for the engineers to see. Can you please confirm which version and build are you on? Thanks
  13. This is an issue we are aware of and are working to find a fix. There is a workaround however, if you check out the Data Tag AND the objects they are tagging, then the association will remain. The associations are lost after Save and Commit if only one of the two is checked out.
  14. @Amorphous - Julian Symbols save objects for reuse, essentially as smart copy/paste. The objects are incorporated into a symbol definition, which is a resource that can be selected from the Resource Manager. When a symbol definition is placed into the drawing, a symbol instance is created. If you attach something to an instance only that instance will have that, as opposed to attaching it to the definition when every instance will have it.
  15. The Data Tag will only work with objects that have the data set that it's picking up the values from - that is why you had the dialog saying 'Current Data Tag requires the following data to be attached to the symbol' - apparently you were trying to tag a symbol, not a wall. It also gives you a choice to tag an instance or a definition of a symbol. For example if a Data Tag is picking up Width value from a Door style, it will only be able to tag Door objects, you would need to set up another one for Windows, or if it's a Record Format, there needs to be one attached to the object you're trying to tag.
  16. Hi @Amorphous - Julian , I've been away for a couple of days so haven't been able to respond. Glad to see issues being sorted though. 👍This is the way to do it. I think you can also add a dimension suffix to the formula too - just mm or " at the end after brackets should do the trick.
  17. @_James It will work on a Mac as Chorus is as you say cloud based and in a browser. Previously we were not able to integrate with them because they had only Windows based plug ins, but now they had gone browser based you will basically be able to open the browser from within Vectorworks and log into your Chorus account to link the Spec to the model
  18. 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)
  19. @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.
  20. 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. 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 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.
  21. @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. Correct.
  22. @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. 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?
  23. 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! Luka
  24. Hi All, 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. 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 The webinar will cover a number of different Energos features, this is the description: Energy modeling in the early design phase Climate change and sustainable design is at the forefront of today's conversation.
