[Bldg-sim] Low-flow Fixtures and LEED

[Robby Oylear]

Based on a LEED CIR dated 4/25/2007 (see below) domestic hot water savings
cannot be claimed for the use of low-flow plumbing fixtures, even though
Appendix G addendum a specifically states that credit may be taken through
calculations.   Have there been any changes to LEED review methodology
since this CIR was released that allows credit to be taken?  Previously we
have taken credit for low-flow fixtures and it has been accepted by the
reviewer, but have recently come across this CIR which seems to state
otherwise.

 

The reasoning behind not allowing it doesn't make a whole lot of sense.
Water efficiency and energy efficiency are two separate animals, and
getting credits under WEc3 Water Use Reduction does not equate to getting
energy efficiency credit under EAc1.  It's not like this would be the
first time LEED has allowed double dipping (EAc2 Renewable Energy is
allowed to be used under EAc1 as well).

 

Is there a legitimate way to take credit for the energy reduction of
low-flow fixtures for LEED?
