The least effective method of slowing down the energy transfer out of the house by conduction would be a single layer of stone only. This is because stone is a good conductor of heat and does not have the insulating properties that the other options have.

Here's why:

1. Single layer of stone only: Stone is a dense material with high thermal conductivity, meaning it allows heat to pass through it quickly. This would not be effective in slowing down energy transfer.

2. Cavity: A cavity wall is made up of two walls with a gap or 'cavity' between them. This cavity acts as a barrier to heat transfer, making it more effective than a single layer of stone.

3. Bricks and blocks with a low thermal conductivity: These materials are specifically designed to slow down heat transfer, making them more effective than a single layer of stone.

4. Insulation: Insulation materials are designed to resist heat flow. They have low thermal conductivity and therefore are very effective at slowing down energy transfer.

So, the single layer of stone only is the least effective method in this list.
