How significant is the cost to heat/cool the extra volume created by vaulted & cathedral ceilings? Of course it would vary by size, but is the extra volume a big cost once it's brought to temperature the first time?
Well ... if it takes so much energy to heat 10 ft cu, then it will take twice as much to heat 20 ft cu. For ease of calculation, assume standard construction/insulation and a cathedral with a 45 degree slope ... and assume the wall height in the area below is the same height as the peak is above the wall. That would make the ft cu in the cathedral part 50% the volume of the room below it. So that would be ... let's see now ... 50% more energy to heat or cool the room with the cathedral ceiling ... period , ... er .
But I do like my cathedral ceilings, and I do have fans installed up there to circulate the hot air in the winter.
