Making a house with a crawl space more energy efficient. Tips/thoughts?

Looking at a house that we like a lot (it's ~15 years old). Problem is it's off the ground. Our current house (65 years old) is off the ground and when we put our list together for "wants" in a house, on the ground was first.
So, what can be done to remedy cold floors and high energy bills that this house has/will have? 4" of spray foam? Heated floors in bathrooms? What else?
Or should this be a deal breaker?

Now we're talking about crawl spaces?

Seems like you should pick another house if the first thing on your "wants" was on the ground

Haul in some dirt and get a shovel. It'll be on the ground soon enough.

Couldn't get past the title with that grammar.

Install Clean Space. Fully encapsulated and dehumidified. No more mold, no more bugs, no more air drafts, and a kick arse clean storage space.

3" of closed cell foam bruh. Forget that cleanspace nonsense.

1" of 2 pound closed cell spray foam on the bottom of the floor will seal and give you about R7. that will be a big step.
at only 15 years old, the windows and doors are probably good. go into the attic and foam every hole (wire, pipe, etc.) in the top of a wall plate. the foam on the floor will catch the holes in the bottom wall plates. add insulation to the attic.

Double pane windows should be priority number one if you haven't already done it. You really don't lose as much as you'd think through the floors, unless your crawl space is abnormally large.

We have new windows in our current house. The issue is that in the winter the floors are ice cold. We don't want that in our next house so we want to prevent it.

Nonsense?

Could encapsulation be done to a pier and beam structure with lattice between the exterior piers?

I wouldn't think so. Very little chance you could get a complete seal, nor be able to dehumidify sufficiently. Spray foam might be your best bet with that arrangement.

That's what he said.

In case you didn't read the link:
quote:
Crawlspaces should have a continuous sealed groundcover of vapor diffusion resistant materials, such as taped polyethylene or, preferably, a thin poured concrete slab over polyethylene with perimeter and control joints sealed. When the crawlspace ground level is below the ground level of the surrounding grade they should have perimeter drainage just like a basement. There must be good drainage away from crawlspaces (refer to Information Sheet 101: “Groundwater Control”). Crawlspace design and construction should also provide drainage for potential plumbing leaks or flooding incidents by sloping the ground level to a drain.
Crawlspaces should be insulated on their perimeters — they should not be insulated between floors. Crawlspaces insulated on the perimeter are warmer and drier than crawlspaces insulated between the crawlspace and the house.

My house is off the ground and I have all wood and tile floors. Never noticed them being cold. My energy bill isn’t high.

It’s just a complete waste of time and/or money, and honestly seems like it wouldn’t last but a few years. Closed cell FTW, vapor barrier, seals holes/penetrations and adds structural integrity to floor system. Solid all the way around.

Extension service has good paper on insulating crawl spaces
