Heating and Cooling degree days


I’m wondering if it’s possible to recreate an Heating and Cooling degree days chart in Ladybug tools using the weather data from an EPW file. Can anyone assist with this matter?

Thanks in advance.

Yes, use the LB Degree Days component with one of the two chart components.

Hi Chris,

Thank you so much for your assistance. I attempted the steps you recommended, but unfortunately, I’m unable to generate a graph displaying the intersection period of HDD and CDD. I’ve attached my definition here. Could you provide guidance on how to create the intersection graph I’m seeking?

I appreciate your help in advance.

You can try the native GH QuickChart. I recommend exporting the data to excel for better control.
