Glazing ratio Clarification and comparing simulation datas

Hi,

I have two doubts:

Thank you,

Hi Vinu,

  1. It’s because how you modeled the surface. I just remodeled it (deleted the surface and cap the geometry) and it works as expected.

  1. I’m not sure if I understand the question. You can run all the cases that you want one by one and then import the results all together. What is exactly your problem/doubt?

Hi Mostapha,

Thank you, I don’t want the opening at the lower end at all. I will try deleting the surface and cap the geometry. Should I just rebuild the model to the specific window dimensions I need? regarding my second doubt I sent you a message.

thank you once again!

Hi Vinu,

  1. To clarify with the sill height, this input works on a surface-by-surface basis and is not absolute to the zone (that could easily create conditions where the input glazing ratio did not match the actual geometric glazing ratio produced).

You probably want to use the addHBGlz component for your case and make a custom window surface (perhaps doing so parametrically with native GH components if you still want to be able to change the glazing ratio). I think this addHBGlz component will be particularly helpful if you sync with the Honeybee github since Mostapha just put in the capability to plug in an entire zone to this component a few days ago. Now that you can plug in an whole zone and the component will automatically figure out which surface of the zone the window should be belong to. Immensely useful for cases like yours.

  1. Are you looking to evaluate the effect of the blinds on thermal performance or on daylight?

Hi Chris,

I have an interface in html where people can choose how they feel, I following the pmv 7 scale model. Hot, warm, slightly warm, neutral, slightly cool, cool, cold. When they make their choice of expressions, I am predetermining the options and sending it to grasshopper/ladybug(like a schedule). I know I can do this option as each case but I am wondering whether I can program to run the simulation through all options or if you have any other way to go about it, could you let me know? I am not an expert at programming but I am learning.

This is what I messaged Mostapha too and I have attached my research abstract to give you an overview of what I am doing.


Thank you Chris and Mostapha!

Hi Vinu,

  1. Chris means to update your components to the latest version (which lives on github). You can use update components to update your components or you can download it manually from Github. Here is an example for the new version of the component (http://www.grasshopper3d.com/group/ladybug/forum/topics/is-there-a-…).

  2. Thank you for sharing the image and the abstract. It’s an interesting approach. I’m not sure if I understand how the feedback loop works but here is my 2 cents based on my current understanding.

If the geometry is not changing in your case I think the best approach for you is to export the idf file once from Honeybee, and then run your cases from the command line in the server.

In this case you will have one main .idf file which looks for some .csv files as the schedule. Now you can re-write the csv file and run the simulation from the command line and parse the results back.

Based on the number of your scenarios you may want to have a couple of idf files for different cases and run them all in parallel. That should give you a better performance.

I hope I understand your problem right! Feel free to continue the conversation here if you have any other questions.

Hi Mostapha,

How to connect many idf files and run them all in parallel?

Vinu

There is no component in Honeybee to do this but you can develop your own. Here is a code example that Honeybee uses to run multiple daylight simulations at the same time: https://github.com/mostaphaRoudsari/Honeybee/blob/master/src/Honeyb…

Thank you for the example model!
