I am doing some research on LEED v4.1 O+M and I have a number of questions.
I am going to post them here (I know it is a lot) hoping someone knows the answer for a few of them, maybe.
thanks !!
a) How do we calculate the gross floor area without ARC?
b) How do we calculate Weighted occupancy ? could not find example calculation anywhere
c) How do we calculate Weighted operating hours? could not find example calculation anywhere
d) How do we calculate outside temperature adjustment factor? could not find example calculation anywhere
e) Where can I find the Table 2. Operating hours adjustment factor ?
f) How do we calculate the operating hours per week to find the adjustment factor?
g) Where can I find the calculation behind the Source Energy Score, am I right to assume that this would be the same three equations from the GHG calculations without converting them to GHG?

Do you find some answers? I have the same problem :-)

Hi,
Based on my knowledge, I found groos floor area based on the simulation software that I use normally which is Designbuilder. For weighted occupancy there are equations in the beginning of LEED V4.1 guidance, to calculate the weighted operating hours, and occupancy. And also you can do that in the Arc platform. In some steps you need to define operation hours of building and then use equations.
