I have a query about the 'Daylighting Grid Component'. Is it possible to change some of its parameters after a simulation ended? I mean, I have run a simulation with a specific 'Lighting  Power Density' and a specific 'Lighting Control System'. But I want to change both values just for comparison. Do I have to run the simulation again? 

I understand that the *ill file should not change, so I think the 'Lighting Energy (LE)' and the 'CBDM metrics' could be calculated without running the simulation again because it is just a matter of math. How could I assign new values in both parameters in the 'Grid Viewer' or in another grasshopper component?

I hope you can help me.

Many thanks in advance.

Hi Abigail,

The grid viewer has (hidden) inputs for resetting metric thresholds, but not the lighting power density or control system.  The former you could easily calculate yourself with a multiplier, but the latter does require a re-run in the current setup, unfortunately.
