For my case, it was worse. When normalized to dollars, I spent nearly 2x more in HVAC expenses compared to driving's fuel costs, and that's with a modest commute (20 miles). Its much less energy intensive to air condition one large medium-density building than many smaller low-density buildings.

That sounds like you're either running your HVAC at extreme temps or have very poor insulation.

Or that he is running HVAC for his 2000 sqft house, vs running HVAC for his 180 sqft office space (where 180 sqft are dedicated to him out of some large space shared with others).

Big family house in the suburbs with aggressive demand scheduling (ie, we let the temp float a fair amount when nobody is home) versus high-efficiency car.

Could be, but it's also likely that 1x big HVAC is more efficient than 10x smaller units.
