SESSION:
The recent fashion for Passive House construction and separately, a new focus on carbon accounting for commercial buildings, has rejuvenated the idea of highly insulating enclosures as an alternative to providing comfort with mechanical systems only. The Passive House approach is also being applied to large buildings requiring non-combustible enclosures.
Building codes require steel stud based building enclosures to use continuous exterior insulation or "ci". With ci comes secondary metal framing for insulation and cladding support, which can dramatically reduce the ci effectiveness, similar to the manner in which steel studs themselves reduce the effectiveness of cavity insulation.
Wood studs are close enough in resistance value to insulation that 1D parallel path spreadsheet calculations (heat flow inside to outside) are reasonably accurate. Steel studs accelerate the transfer of heat through an assembly in every direction (heat flow inside to outside, up and down, and sideways into the interior of an assembly). Reviewing non-combustible steel stud assemblies requires 2D or 3D calculations.
THERM is a free 2D heat flow analysis program created and maintained by the Lawrence Berkeley National Laboratory of the US Department of Energy, already commonly used in the rating of window performance according to CSA Standard 101. The Passive House certification process extends the use of THERM to the assessment of the thermal bridging in wall assemblies. Webinar participants will become aware of how THERM can help them optimize the performance of their non-combustible exterior assemblies.
