Re: [EnergyPlus_Support] Daylight Factor

There is a way to produce DF csv noted in the documentation, but I don't know if it fits your definition.

Hi Santiago,

Thank you very much for your reply.

The "Adding Daylighting" video does show how to setting the simulation but it does not explain how to actually view the results.

In my case, it is important to work within the EnergyPlus environment and not taking the model out to an external one (lie Radiance), this is because I am going to do some batch simulations and export some CSV files with some data.

Like you, I`ve got the feeling that a DF analysis should not be very difficult to perform in EnergyPlus, and yet, I couldn`t manage to control it.

Thanks anyway,

Yair,

Dear Yair, I don't know of any tutorial that explains exactly what you are asking for, but the following OpenStudio tutorial gives you a very visual idea of how Daylighting analysis works in Energyplus, its not too difficult to implement it. You can output Illuminance maps, and do some post processing to calculate average daylight factor.

Openstudio went a a lot further and added Radiance pluggin for co-simulation with Energyplus for more accurate daylighting analysis. Here

Best,

Santiago.

Hi Everyone,

I am trying to find a clear and easy-to-use tutorial that explains how to perform a Daylight analysis in EnergyPlus.

Basically I`d like to calculate the average DF and the uniformity.

Can anybody recommend some tutorial?

Thanks!

Yair.
