HTB (Physics)

In Physics, HTB is the heat loss due to linear thermal bridging when calculating the energy performance of buildings. It appears in both United Kingdomcite web |url=http://www.techlit.co.uk/JPA%20Designer%20manual%20v5.pdf |title=User Manual, JPA Designer |accessdate=2007-07-06 |work= [http://www.techlit.co.uk JPA Technical Literature] ] and Irishcite web |work=Sustainable Energy Ireland |accessdate=2007-07-06 |date=2006 |title=Dwelling Energy Assessment Procedure |url=http://www.sei.ie/getFile.asp?FC_ID=1591&docID=188] methodolgies.

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
