Changing rooms in adjacent LEED building

Hi Angel, yes, as long as you include the adjacent building's occupancy in your calculations (as you've noted above, there is enough to cover both buildings) and you meet the distance requirement (within 200 yards of a building entrance).

Follow up question, must we include the shower(s) in the water calculations?

 In v4, you would exclude the outside showers from the prerequisite calculations and include them in the credit calculations. This isn't defined super clearly for v2009, but it's consistent with how LEED-CI spaces using base building fixtures are treated in v2009. Basically keeps you from being penalized in the prereq by any lower-performing fixtures but not claim additional credit if your occupants are using low-performing outside fixtures. So I would consider that the best approach.

Thank you, Emily. LEED 2009 has a document entitled 'Supplemental Guidance to the Minimum Program Requirements revision 2', it states on page 25 that the changing rooms may not be included in the calculations for WE prerequisite but it does not mention the WE credit. Can you point me to the reference for CI?

Sure, I'm thinking of the water use reduction additional guidance doc: https://www.usgbc.org/resources/water-use-reduction-additional-guidance The last 2 pages address CI, Case 3 or 4 are the two options CI projects in this situation can use.

Thanks for the reminder about the example in the MPR guidance! Looks like that and the parking garage example both made it into v4 as clearer, credit-specific guidance.

Of course, the showers probably won't push your project over or under a credit threshold, so you should be fine either way.

Case 3 and 4 are confusing me. Do I claim the shower in my WE credit calculations? I have only 5 FTE but combined with the staff of the adjacent building where the shower is located, there are 99 staff total. I am using LEED v4 CI so there is little indication as to what I should do in this case so LEED 2009 is all I have to go with.

Case 3 and 4 both state fixtures are located both inside and outside tenant space. There are no tenants in our project, it is a university campus, everything is owned by the university. I don't understand why in each case it was decided the fixtures are included or excluded from the WE credit calculations.  

Apologies, the original post was referencing NCv2009, so I assumed yours was the same! For CIv4, it is noted in the reference guide under Step By Step Guidance:

Prereq: "

Calculations for the prerequisite are based only on the fixtures within the tenant space (note that this differs for WE Credit Indoor Water Use)."

Credit: " Include fixtures and fittings necessary to meet the needs of the occupants. Some of these fittings and fixtures may be outside the tenant space (for Commercial Interiors) or project boundary (for New Construction). "

Hope that clears things up.

Thank you, Emily.
