I am trying to calculate the energy lost from the beams of a block and beam floor to a buildings foundations.

After much research into building physics I am very confused about how to do this. It is is thermal bridging but none of the calculation methods that I have found seem appropriate to me. It also seems increasingly likely that I will need to find a modelling programme which I would rather not do.

Can anyone help?

nearly all walls thermally bridge down to foundations (except Viking House ones)

I would concentrate on robust air sealing and durable airtightness for your floor, not as easy as you may think, wind coming up door linings will far outweigh any thermal bridging

use perimeter insulation, maximise floor insulation.
