This may be off topic, so you can contact me privately.
I am trying to build up a plot as shown on the last page of:
Climatic potential for passive cooling of buildings by night-time ventilation in Europe
N. Artmann, H. Manz and P. Heiselberg
Applied Energy, 2007, vol. 84, issue 2, pages 187-201
I have an EPW file for my location. However my question is how should one go about doing the summation of all the CCP (= degree-hours) per night please? I can open up the EPW in Excel, then superimposed the sine wave oscillation for the room temperature.. and then?
Any help is sincerely appreciated..!
