what temp do you use to determine this? degreedays.net uses 16.5C as the default but that made little sense to my energy usage - I don't cool to 16.5C and I turn on the heat above that level so I use 18.5C for both HDD and CDD. It turns out CDD means very little in my energy usage so I don't do much with it.
