Honeybee (in Dynamo) illumination result extrenly high #109

Open Koziu233 opened 4 years ago

Koziu233 commented 4 years ago

Hi,

I'm new to honeybee and is attempting to run a point in time gride based daylight optimization within Dynamo (Revit) -Honeybee.

I'm aware that the Collect Rooms and Spaces node does not work well according to the current Autodesk policy. I chose to use the traditional way of making HoneybeeSurfaces.

However, I found the illumination result in lux being extremely high which seems unreasonable. At some point close to the window, it even went up to over 30,000 lux. For example, the red point as shown in the figure.

I'm not sure if I made any mistakes when setting up material properties. The values I use for materials:

And I'm using weather data of London from energy plus:

The script running seems to be successful without having problems, but the result seems to be strange. It will be good if I can know where I made mistakes or in which part my knowledge is not enough. Thank you very much.

My files: (currently using Dynamo 2.0.3) File_cc.zip

This is not the correct place for this issue and it should be posted here instead. Also, our Dynamo plugin is currently deprecated in the newer versions of Dynamo so you will likely have to go to an older version.

I transferred this issue to the correct repository.

Did you check the values in the weather file or try to run the study for an unprotected sensor for the same hour? What was the result in that case?

Also just to understand how the package worked in case what version of Revit are you using? It looks like the issue is with the newer versions of Revit and not necessarily Dynamo itself.

Hi Mostapha,

Thank you for your quick respond, I'm currently using Revit 2019. I tried to run the same point in time analysis with the same weather file with using Honeybee sample Revit model within the package and that CollectRoomAndSpace node. I got the highest value at approximately 3000 near the window which I think could be reasonable. This led to my confusion of whether I made any mistakes during creating HoneybeeSurfaces.

I'm currently using weather file of London from energyplus, I also double checked with files in other cities, the results all seems to be too high, so not the problem of weather file I think.

And also regarding a previous issue

https://github.com/ladybug-tools/honeybee-dynamo/issues/103

ERROR: Local variable 'combs' referenced before assignment.

I also met the same problem when trying to output an annual analysis result. Is there any chance that this bug could be solved?
