FAQs about WEp1 :

In the credit calculation worksheet for indoor water usage, does each fixture needs to be listed separately (toilet #1, toilet #2, etc.) or can the fixtures can be grouped together, for example, with all toilets with the same GPF?

What do we do if we do not have cut sheets for fixtures installed many years ago?

EBOM-v4 WEp1:Indoor water use reduction

Cutsheet unavailable

If manufacturer documentation is unavailable and the flow/fixture rate is unknown is it allowed to physically measure and time water consumption rates for at least a 20% of the fixtures of each fixture type in the project building similarly to EBOM v2009? Thank you in advance.

Charalampos, That is a sensible option (and was the way the process was completed in pilot and version 2) but, you really will need to articulate why you can't get the cutsheets of the make and model of the fixtures. Agreed the fixtures may not be marked up with flow rates, but manufacturers documentation takes all the questions away that GBCI might send your way.
