Section 02 of 04
Cold bridges the camera finds first
A wall can measure well on paper and still carry heat out along a line through it. These are the junctions where a material that conducts well crosses the insulation, how they are quantified, and why they matter more the better the wall gets.
PLATE 1Thermography works in the hour after sunset, once solar gain on the surface has dissipated and the fabric is still warm.

Cold bridges the camera finds first
A thermal camera at dusk shows lintels, balconies and wall plates as bright lines, because heat is going round the insulation rather than through it.

Ψ-values and the y-value
Linear thermal transmittance is how the junctions are accounted for, and ignoring them is how a calculation flatters a building.
The balcony problem
A cantilevered slab is a fin conducting heat out of the building, and the fixes are structural rather than thermal.
