State of Practice for Thermal Bridges

Hello all

I'm not a modeler myself but do a lot of design review of project architecture plans and I am also heavily involved in advancing building codes. I have four questions for you experienced modelers out there that would help me tremendously -

  1. How common (and how thorough) are thermal bridges accounted for in building models?

  2. Would you say that modelers are commonly (or rarely) using the "presolved" thermal bridge solutions from references like BC's Building Envelope Thermal Bridge Guide avail here link text

  3. Do you see modelers using BC-type thermal bridge accounting more in future? Are modelers going in that direction, or would you say you are already there?

  4. Finally - to what extent is there a feedback loop between the architectural design team and the modeler to ensure that any thermal bridge mitigation which may have been needed to meet code, satisfy LEED, etc gets "into" the project drawings and built? (Or, the corollary - that poorer performance is accurately represented for buildings which are not thermal bridge mitigated.)

Thank you!
