Hi,

I was wondering if there is any way to get Vertical Sky Component with DIVA4RHINO?

Thanks in advance,

Frank

Hi Frank,

Don't understand your question... what is a vertical sky?

Jon

Hi Jon,

Vertical Sky Component is a new daylight metric that is currently use in some countries (UK, Sweden, etc...). similar to Vertical Daylight Component. It helps designer to know the potential of daylight on the façad. So it could be use in early design phase where the building layout is not ready yet. This study from Lund University explain more in details this parameter.

Hi Frank,

Thanks for the link. That's pretty straight forward to do with existing components -- simply compare vertical illuminance at the window (-ab 1) with horizontal illuminance sans context buildings.

Example definition here.

Hi Jon,

Thanks for sharing this script that's indeed pretty straight forward :)

Just one question though. We need to input CIE overcast sky, is the overcast sky that you set is enough? It seems the weather file is required but if it's CIE overcast sky I souldn't need the weather file right?

Best,

Frank

The sun position determines the overall brightness of the sky, but in this case we're taking a ratio so it doesn't matter. (As long as the sun is above the horizon.)

Hi Jon,

Thanks for your support.

I'm going try this VSC for some projects.

Best,

Frank
