Heat loss due to linear thermal bridging

The heat loss due to linear thermal bridging () is a physical quantity used when calculating the energy performance of buildings. It appears in both United Kingdom[1] and Irish[2] methodologies.

Calculation

The calculation of the heat loss due to linear thermal bridging is relatively simple, given by the formula below:[3]

In the formula, if Accredited Construction details used, and otherwise, and is the sum of all the exposed areas of the building envelope,

gollark: But only after considering the previous ones.
gollark: Now, ignoring the lack of consideration, consider this image instead.
gollark: Your lack of consideration has doomed us all.
gollark: Oh no.
gollark: Please consider all three of these images thoroughly.
