Creating a custom EPW for annual clear sky radiation analysis


#1

Hey,

I would like to run an annual analysis with clear sky conditions. Is there a tool that allows you to edit the EPW file within grasshopper?

Has anyone been successful in generating this type of sky?

I have tried converting to CSV and editing the file in excel - converting back to EPW…but do not trust the results.

Any help would be much appreciated.

James

Hi @JMS,

Please have a look to this. There is an example file attached by Chris. Thanks

Also, if you have not used HB+ yet, I recommend starting with this example file:
http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Peak_Solar_Radiation_Massing_Study&slide=0&scale=1&offset=0,0
… which runs a radiation analysis using a clear sky.

The link that @MohammedAlshayeb posted shows how to create the EPW with the clear sky, though.
