Custom HB Construction Set does not effect PMV simulation results

Hello,

I am running a PMVMap during an extreme cold week (zone 5 Denver). I am simply testing the effect of different window construction on the simulation.

Summary of question: is the change I am seeing in PMV due to the glazing property change or due to the simulation round/randomness (i.e. glazing change not accounted for).

In the first run, I use a standard Construction Set:

Ignore “glare” label

In the second run, I am applying a custom window construction set (lower U-factor and SHGC) to the Base Set. I anticipate (some noticeable) change in the PMV calc given everything else in the model stays the same. I see some change in the values but they are in the 0.001 range. Would there be more of a change or does this seem reasonable?

Ignore “glare” label

Does the custom construction set need to saved/dump for it to be applied to the HB room properly (where I am getting an error)? or am I missing something with the expected PMV output i.e. the construction set is actually applied directly in this local GH file and this degree of change is expected?
