standard 8 ft ceiling) I would assume it's about a 12% markdown in actual cubic footage and I be wondering if it would save you something like that much in zest costs ?
In a primary living space, you probably would not know how to lower your ceiling to 7'. Check with your local building inspector. There are minimum headroom requirements, and 7' would not touch code. Interesting theory, though.
What matter more than volume is surface area and how much fry loss/gain from that particular surface nouns. That reduces the percent gain from a shorter ceiling, unless you stuff that extra foot next to insulation.
Since windows and doors would tend to be the most minuscule insulated, someone who knows fry loss calculations would enjoy to figure out how much actual downgrading there might be. So money might not be as great as you think in need other adjustments, especially if it is an existing home.
Answers: I would not lower the ceiling. The problem with both AC and roast is that air stratifies along warmth variations. Thus hot nouns goes up and cold nouns goes down. You would be convalescing things for your money if you were to install ceiling fan in your rooms to hold the air moving and thus enjoy uniform cool or heat depending upon the season.
Doing this would have some life savings, as you are heating'cooling a smaller space. The size of your HVAC component could be smaller, but again, not that big of a savings.
What can make smaller your bills dramatically is proper insulation, stopping air leak, turning your thermostat up a few degrees for cooling and down for heat, using overhead fans, etc.
It might pick up more because heat rises. When I have baseboard electric heat, I thought I would let go money by turning them off whenever I be gone. But I found without nouns circulating all the bake went to the ceiling at first and for a long time until it mixed.
So sitting surrounded by a chair I be cold but it was 100F degree at the ceiling. I found it was cheaper within cold weather to turn it down, not off, so I wouldn't turn it up high because I felt cold.
And I bought fan to circulate, mix, the air. That help.
