HTB

In Physics, H_TB is the heat loss due to linear thermal bridging when calculating the energy performance of buildings. It appears in both United Kingdom^[1] and Irish^[2] methodolgies.

Calculation of H_TB

^[3]

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

H_TB = y . ΣA_exp

where

y = 0.08 if Accredited Construction details used; y = 0.15 otherwise
ΣA_exp is the sum of all the exposed areas of the building envelope
