We have a garment factory project that has a Main block and two toilet blocks (separately for Men & Women).
The Main block has cutting & sewing sections only and the occupants of the Main block only will be utilizing the Toilet blocks built next to the main block.
But the Main block and Toilet blocks has no structural connectivity, (but only via a passage at outdoors), hence only Main block is to be registered under Single Building certification.
The major consumption of water for the Project is only in the Toilet blocks.
If the Project with Main block alone be registered under LEED New Construction 2009 (Single Building Certification), how to calculate & meet the water use baseline (Water closets, lavatory fixtures) of the project where majority of water consumption is in the Toilet blocks only which is outside the LEED Boundary.

Hi Aswin
In fact you can include the toilet blocks in the project --LEED doesn't consider a toilet block such as the one you are describing to be "occupied" (I've done several garment factory projects) and the walkways and grounds around the toilet block really should be in the boundary as well. Only in the case that the toilet blocks are really buildings in their own right are they needing a separate certification. So best to re-draw the boundary and include them. Otherwise you should register the project and ask your review team what to do (using the on-line feature), since your reviewer would have a preference as to how you deal with it.

Agree with Melissa here… all fixtures used by project occupants should be included in the water calculation and the toilet blocks as described should be included within the LEED Project Boundary.

Thanks Melissa & Carlie for your suggestions!.. Appreciate your support!..
As per your advice, on including the toilet block into my LEED Boundary, should we account the Toilet block area also into my project built up area for LEED certification?
And also should we consider the Toilet block for all the credit calculations such as roof area, LPD lighting calculations, material calculations, etc.
How to include the health faucet in the Water Use calculations, which is not listed in the LEED Water Use Reduction Calculator.
Thanks in Advance!.

Hi Aswin, yes you should include that block in all the other calculations. However I'm not sure what you are asking about in your last question, I'm unfamiliar with a "health" faucet. Please explain!

Hello Melissa!. Thanks again!.
I meant Bidet Shower as the health faucet which shall be used in the Toilets for cleaning. Clarify on how to calculate the water use calculation for the bidet shower.
As per your earlier advice, since Toilet block alone cannot be certified separately, how about the blocks like STP room,Pump room & Guard room which are separated from the Main building be considered as per LEED.
Should those blocks also to be included in the LEED boundary and to meet all the prerequisite & credit calculations.

Dear Aswin, this is not counted. Bidet shower is a bit like a service sink or bath tap, it makes no sense to have low-flow, but I think the actual reason it is not mentioned in the LEED manual is that it is not a typical feature of US sanitary ware. Potentially, as LEED becomes more international, it could be that like the kitchen spray there will be an upper flow limit rather than having it included in calculations or omitted altogether. For now we don't count it.

Melissa, Thanks for your insight on the Bidet shower.
Can you help me in the below clarification also.

Yes that's right. For instance Guard room is probably less than 10m2 which means that it can be excluded from energy modelling and outdoor air calculations, but you can include in SS and MR credits. STP room and pump room unlikely to have 1 FTE so the same applies. Download the MPR document since it lays it out clearly.
