Hi,
I am trying to get an hourly UDI, however, I am not sure which component can give me an hourly UDI.
Could you please help me with that?
Thanks in advance
In the new LBT plugin (version 1.2.0), you should use the “HB Annual Daylight Metrics” component to perform customized postprocessing of daylight results:
To get UDI for an hour, you would just have to plug in an _occ_sch_ for the hour you are interested in. You can also just use the native Grasshopper “Read File” component to parse the illuminance matrix into Grasshopper if you want to quickly scroll through hour-by-hour.

That’s not a component from LBT 1.2.
It seems you are using Honeybee[+] 0.0.6, which is mostly deprecated at this point. Upgrade to the latest LBT plugin on Food4Rhino.
thank for comments @chris
i need udi values ​​for a month with hourly time step (720time). But I can only output udi annually
i want to have UDI values for all hours of a month (maybe 720 time ) . to create a excel file from hourly udi .
I really need your help.
Please help me if you gain UDI hourly results because I have the same problem .
Dear chris,
I could not solve my problem, could you please check the below picture, I have the same problems.
If you only want to evaluate Annual Daylight for a subset of a year, then just apply the hoys of the analysis period to the input Wea like so:
You’ll just have to multiply the results by the reciprocal of the fraction of the year you are evaluating.
The .ill files that are output from the component are actually CSV files where each row is a sensor and each column is an hour of the simulation. So you can already import them to Excel. Still, I’ll add a component that imports the illuminance values to Grasshopper as data collections soon.
I also just added a new component to the development version of the LBT plugin, which can import the values from the .ill files as a data collection. It’s called “HB Annual Results to Data” and it allows you to get the hourly illuminance for a particular sensor or list of sensors.
The component will be in the LBT 1.3 release (coming soon) or you can get the development version of the plugin by running the “LB Versioner”.

Cool, thanks Chris. Will this be able to generate a 8760 list? where the values outside of the “Sun_up” list is zeros?
Yes. Just deconstruct the data collection with “LB Deconstruct Data”
