[Bldg-sim] Thermal bridges

[Christian Cianfrone]

LEED is no more specific than ASHRAE 90.1, which is not very specific on thermal bridges other than those occurring in the assembly (studs, cladding attachments, etc).  It is not specific about thermal bridges such as slabs, shelf angles, parapets, etc.

Aside from LEED, standard linear transmittance values are available for common North American details, as per ASHRAE 1365-RP.  Our company authored the report, which can be found here:

Subject: [Bldg-sim] Thermal bridges

Dear all,

I am a student from Switzerland, studying building physics and I would like to ask you how LEED takes into account the thermal bridges.
Are there specific values for the linear thermal transmittance, like Passivhaus?

I would really appreciate if somebody can answer to my question.

I would like to thank you in advance,

Best regards,

Kyriaki Goulouti
