My house has a above ground crawl space. I've found some minor things that have really helped.

When they cut the hole in the floor for my dryer vent, they cut a 5 inch hole and I have a 4 inch dryer hose. When I got down and felt, I could feel cold air coming through. I got some spray in foam and filled up the gap. Foam says it will handle the temps and for 4 months it has done just fine.

I could also feel cold around my door. Weather stripping was good, rubber seal was good. I pulled the trim off. Sure enough, the gap between the door frame and the wall, you could see daylight. Out come the can of foam again.

I have a Gen-Air stove. You know the type, I can bar-b-que, swap burners and have regular burners, or even put in the flat top for pancakes. But it has a fan in the center. It sucks everything to the center of the stove top and down it goes. When I place my hand above that, I can feel cold. When I installed that, I made sure I put in the vent on the outside of the house so it had a trap door. Even put screen over it to keep critters from working their way in there. It still leaked enough so you could feel it. So I cut a piece of wood and put a handle on it. Now, I remove the center grate and place this piece of wood in and it completely seals the air ven/suction fan. Course, you want to make sure you remove it before using it. So I put a little sign right above the on/off switch saying, "Make sure you remove the block". So far, so good. Stove also has a hood fan above it so for normal operation we use it. But if we bar-b-q, we have to use the center fan also.

Drains in the sinks. I could feel cold air in my sink drains. Course, as you know, they are all vented to some extent. So I simply put the stoppers in them while not in use.

After encountering the door problem, I pulled the trim around windows. Yup, a couple had the same problem. Out came the foam again. haha

My windows are excellent. I have 2x6 walls. One glass window (slides up and down) is on the inside wall. The other glass and screen (also a slider) is on the outside wall, giving me 6 inches of air gap between the two. They are really nice.

Hope my experience can give you some ideas.

2 years ago my daughter and son-in-law were renting this house from me. They are fairly energy concious. Their bill Run in the $300 per month range. That's gas and electric. Now that I've done the adjustments to the shack, my gas and electric runs me about $130-150 a month.

Like I said, all little things that didn't cost more then some scrap wood and a couple cans of expanding foam.
