HTB

From Wikipedia, the free encyclopedia

The correct title of this article is HTB. It features superscript or subscript characters that are substituted or omitted because of technical limitations.
For other uses, see HTB (disambiguation).

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.

[edit] 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
