Hi,
LEED reference document says in the Required document Table (page 309):
- Nonportable water analysis (if use 100% nonportable water) -------------------------------------- 2 points
Does that mean if I use 100% nonportable water, I only need to achieve 01 instead of 10 cycles of concentration calculation?
Please help,
Thanks,
Tom

Hi Thomas and Devendra,
No, aside from use >20% recycled non potable water, you also need to meet the minimum number of cycles without exceeding any filtration levels or affecting operation of condenser water system to earn 2 points (LEED BD+C v4 page 306).
The minimum cycles mean the least cycle can be achieved from one-time potable water analysis. Please kindly refer to LEED BD+C v4 guide page 309 for how LEED defines the minimum number of cycles.
