HTB



In Physics, HTB 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.

Additional recommended knowledge

Calculation of HTB

[3]

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

  • HTB = y . ΣAexp

where

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