I've been reviewing credits for project teams for a while now and cannot figure this out to save my life.
One of my team members has mistakenly entered a bunch (about 88% by tonnage) of commingled waste as diverted on the form. When I changed it to "Waste is commingled; diverted offsite" just to see if the form would ask for backup, the total percentage diverted from landfill dropped from 88% to 77% inexplicably. I've searched the forum up and down and can't seem to find anything that explains this.
Admittedly this is an old project (and thus, an older form), but I've never seen this before.
Any suggestions?
Thanks!

Jake - Many of the early LEED 2009 forms had issues. The version you mention was a Beta (first version). I don't doubt it had issues, but I can't speak to that calculation error myself. You must really have an old project because the v3.0 version came out in August 2010. The USGBC published a Form Fix log to note changes made between versions of forms. The last one from July 2013 is here - http://www.usgbc.org/resources/lov3-forms-fix-log.
You can also read more at this LEEDuser forum - http://www.leeduser.com/topic/beta-credit-versions. This LOv3 Help topic may also be of use - https://www.leedonline.com/irj/go/km/docs/documents/usgbc/leed/config/co.... Check out "My forms says "beta" at the bottom. What does this mean?" and "What is the form upgrade process?" so you can upgrade your forms.

Hi Michelle,
Thanks for getting back to me, and kudos on the form notes.. it is a really old project and at this point we are just trying to close it out. I've recommended updating the forms but it seems the GC is reluctant to work with anything they haven't worked with before.
Anyway about the calculation itself, I think we figured it out. When we entered the commingled portion of the waste, the landfilled materials were actually already part of that number. So, when we listed them as commingled at 88% diversion, the percentage of landfilled material shot up since we were technically counting it twice (once as part of the 88% diversion rate of the commingled waste, and once more as a separate line item on the form itself). So what we did instead is just delete the landfilled waste percentage from the form and kept the whole value of the commingled waste at 88%. That got us the percentage we were documenting/deserved.
Hopefully that made sense, and hopefully not too many other people are dealing with forms this old!
Thanks again Michelle!
