75 -The BS of BS?
Manage episode 357517921 series 2656882
The BS of BS--the bullshit of building science--is Steve's way of characterizing sound building science gone haywire in totally screwy application. Examples include paralyzing worry over vapor diffusion as a way that buildings get wet, insane levels of exterior insulation in below-grade walls, using only financial payback when comparing double- and triple-pane windows (ignoring thermal comfort and durability). Add in over-insulation of window frames, bans on spray foam, and you have the UBIP combined blood pressure skyrocketing.
