At the risk of sounding like a salesperson, have you tried the Pollination Revit plugin (https://www.pollination.cloud/r

If the gbXML files are valid, one option is to use Ladybug Tools or Pollination plugins and create a script inside Grass

Hi @MaRe! I did a quick test and the model is being exported with no issues. See here and here.

I fixed it using the Pollination Rhino plugin (https://www.pollination.cloud/rhino-plugin). Revit's native gbXML export

Hi @MaRe, I uploaded the fixed version here. It was missing the floors as you said but it was an easy fix. C:\fakepath\

Can you upload it to Dropbox or Google Drive and share the link here?

Can you share the gbXML file?

From your description, it is most likely generated by Daysim. If you check the header file there is a field to set the u

While waiting for you I just gave it a try and imported the osm file in Rhino and ran a test daylight factor simulation.

Do you have access to Rhino? I haven't used the Radiance measure for a very long time but if you have a license of Rhino

If you have a measure that does change the gains Honeybee is capable of loading the measure and running it as a part of

Let me check that for you. I didn't get any notifications to approve new accounts on Radiance discourse.

What's happening to Radiance measure in OpenStudio reminds me of what Autodesk does to their products.

I suggest to post this question to radiance forum: https://discourse.radiance-online.org/

What are you trying to do and what is the command you're trying to execute? Try which rad to find the installation path.

Try which evalglare command.

This is a different question and not a comment. Open a new question for that.

Thank you, Rob and Mostapha! Now I have another question which might not be relevant to this forum. But does anyone of y

@rpg777 wea actually takes direct normal radiation and diffuse horizontal *radiation and not the illuminance.

@Funky I assume you mean OpenStudio by Open Suite? Which version of Honeybee and OpenStudio are you using?

The number of lines and the number of points should be the same. In the example that I have sensors are written to separate files and are calculated separately.

Each column is for an hour and there are 8760 columns for 8760 hours however the first column is actually the results for 1 1 0.500. The wea file and so the sky is created for between the hours. Check the in.wea file under radiance\wx folder to see the values for each hour.

@Determinant I'm following your conversations with Rob here. Since OpenStudio is designed to use Radiance as a support for E+ most of what you want to do needs a lot of customization. You can do most of this stuff with Honeybee[+] if you're willing to use Rhino and Grasshopper. Just another option to consider.

What is the solution to change construction properties (in this case u-value) during the simulation in EnergyPlus? Is it possible to assign a schedule to construction properties?

PS: This question is originally posted here by Christian Kongsgaard.

Hi @Julien Marrec, As I commented on GitHub the current version hasn't been tested on Mac. We already made a couple of changes to make it potentially work on Mac but I don't have access to mac to test it. The new Ladybug, Honeybee and Butterfly plugins will address this issue.

CIE sky is NOT generated based on the data from epw file. It only takes the location data (e.g latitude, longitude, etc). Check gensky manual for an example. If you are looking for a climate-based sky then use gendaylit.

Ladybug + honeybee don't have an optimization engine, however there are several optimization plugins for Grasshopper that can be coupled with LB+HB. The short list is Octopus, GOAT and Galapagos. As mentioned by @Waseem you will probably end up to conclude that each of the optimization engines will give you different results based on the landscape of the results and the initial population.

UPDATE: The issue is solved now. Download version 5.0.1.11.

Hi Greg. Just checked again and I still need end-of-line character to get all the modifiers on Windows. I will wait for the new build of Radiance to run another test and will report back here.

I have seen multiple discussions on EnergyPlus email list about modeling atrium (without using CFD) however I still don't have a clear idea what is the best way of modeling an atrium. I am looking for recommendations on:

1. Preparing geometry: Should we split the atrium horizontally in each floor? or should the segments on the top of the atrium should be shorter to capture the stack effect. Is that even make sense considering the EnergyPlus will transfer the radiation as diffuse radiation between the zones?

2. Air walls/surfaces: Assuming that there will be some sort of geometry split, what is the best suggestion for the construction of surface between the geometries?

3. Air flow network: Again assuming that there will be some sort of geometry split, what is the best practice to set up the airflow between the atrium zones?

I'm using rcontrib to calculate number of sunlighthours for a grid of test points. With the help of @Andyrew on this previous question I'm getting accurate results as far as the number of modifiers (suns) is less then or equal to 239.

If I create between 240-420 modifiers rcontrib will generate the results for n-1 of the modifiers (239-419). You can test the this file to recreate the issue. The file is a zipped file but I had to change the extension to tiff to be able to upload it! If you unzip the file and check untitled.dc file NCOLS is 239 however number of modifiers in untitled_suns.rad is 240.

If I create more than 420 modifiers the number of columns in result file will be accurate but one of the modifiers won't be seen by the test points. In the image below you can see the area that are missing the same modifier. The rest of the points return accurate value as they are already blocked by the wall.
