Take the "V" out of HVAC and you are left with a HAC(k) job.

Residential in southern California, that figure is ok. I don't know about Alberta or Havana or Bonn or Quito. It is less for some occupancies, (warehouse), and more for others, (surgury center). You won't find any "typical" value that means anything without more information.

At the 95% confidence level, I'm 63.278% sure that HVAC energy accounts for somewhere between 2.78% and 97.22% of building energy use in the US of A. Or not.
Seriously -- me personally, I agree with the Dept of Energy's assessment. I spent lots of my career doing energy analyses of existing buildings, and they tended to fall into that 40% to 60% slot fairly regularly when in the office / medical / institutional / military category. K-12 schools were much lower since the ones I worked did not operate in summer.
Good on ya,

That's because you don't get to see it hanging on the two metal hooks, all intact, with it's head, and bill, etc. There's never a mistake, unless they swap out while chopping it up for you.
