Peak occupants and FTEs

Since the reference guide states that in a building with multiple shifts you should use only the highest-volume shift in the calculation I would use just only the highest-volume shift (600) BUT you should also consider shift overlap (page 53). Therefore I would use 600 + 300 = 900 occupants for calculating bicycle racks and showering facilities. Any other ideas?

It seems like you could reasonably justify only providing racks for 600 people (or 900 if there is shift overlap). Just make sure to clearly state your case when you submit the credit. And let us know the outcome!

Seems to me that the credit requirements simply weren't really thinking about the possibility of 24-hour occupancy. Given that, they aren't logical. I'd contact GBCI to see if they will give you a different route based on peak occupancy, including shift overlaps.

Have you taken a look at the Interpretations database or found anything from the manufacturing discussion group? LEED HC has a different calculation for shift overlap for this credit. Essentially you add the two largest shift FTEs together and multiply by 40%. That number is then used to calculate the required number of bike spaces and showers. (So your case = 600+300=900*.4=360.) Caveat is that in HC, this credit only applies to staff and hospital have very large staff populations. You don't say what type of project you have. My point is that there may be some room for a more thoughtful look at peak shift occupancy rates and that HC and manufacturing may have some guidance for your project.

Hello all, I am having the same question here, since we are working on a manufacturing facility with 3 shifts and I would like to know how you solved this credit for occupancy with shifts. Did you take the highest volume shift? or did you consider the highest volume plus the next shift? As I understand the explanation for the credit, shift overlap refers to those shifts that are working during the same schedule (for example 1st shift works from 7 am to 3 pm and the 2nd shift works from 1 pm to 9 pm, there is a 1 hour overlap), but when there are no overlap hours it should be only considered the peak shift, is this correct? Thank you in advance. Regards!
