FAQs about WEp1 :

How does the CEE Tier 3A criteria for commercial clothes washers compare to ENERGY STAR certified washers?

Is the WaterSense label really required, even if a non-labeled fixture has a comparable flush or flow rate?

Not all fixture types can get the WaterSense label. Which fixtures do we need to ensure have the WaterSense label for our project?

CI-v4 WEp1:Indoor water use reduction

Kitchen faucet nominal flow rate vs maximum flow rate

We are doing a CI project in Hong Kong and going to select a kitchen faucet for installation in the pantry. The Manufacturer data mentions 3.4 lpm as"nominal" flow rate of the fixture, which is based on a test carried by local authority while requirement for LEED is 6.7 lpm as maximum flow rate. My question is, will it have any major impact on Indoor water use reduction prerequisite approval if we use nominal flow rate value?

If this faucet is a fill faucet, like for a prep or pot sink, you aren't looking for water savings because there isn't any-only heat loss potential if you lower flow rate. Only hand sinks and prerinse sprays count towards savings.

Hi suzzane. This is hand faucet we are talking about. My question is, is gbci too particular about definition ? If I upload specification of fixture which mentions nominal flow rate, will gbci still accept it?
