Yes, but to calculate the daylight efficiency, you first have to know the daylight factor of your room.

It is only possible to calculate the daylight factor if your room contains a window and a daylight calculation has been performed. Make a note of the average daylight value, that can be found in the results overview and follow the second step.

After you have calculated the daylight factor, open the "Daylight" dialog in the "Project" main menu and enter the daylight factor in the correct place and also add the desired illuminance, installed power and the current tariff.

The printout gives you an overview of the energy costs, considering the daylight factor and your installed luminaires.

Dear Basile,

Thanks for your answer! But I still have another question, what's the weather data used by Relux? Is it possible to see the data?

Best regards

Aleck

Dear Aleck


We do not use the weather data, but the sun probabilities in percent per month.

This data comes from https://energyplus.net/weather
