Now, doesn't anyone have a question about some arcane DOE-2
keyword?

No. But DOE2 was underpredicting the heating use in this two-year old mid-box
store in Connecticut; until I revised my simulations based on a survey
by Fred Lugano at WeatherCraft in Vermont. The folks at Energy Design Update
mention insulation "underjobs;" should I call this an insulation "overjob,"
as in "It's five, this job is over!"

 

While ASHRAE performance path calcs require assumptions of zero infiltration when fans are on, that may not be the case in reality. And exactly what should we use for the insulating value of this wall? Funny, the sections are drawn looking much "cleaner."
