FAQs about WEc1 :

We can't get weekly readings from the main building water meter. However we can take daily readings from a water subsystem (e.g. irrigation or cooling tower makeup). Can we pursue Option 2 (water subsystem metering) without pursing Option 1 (whole buildin

What kind of meter reading documentation is required to meet the items requested on the credit form? The LEED Online credit form requests both weekly readings, and then also monthly and annual summaries.

What is the best way to track the monthly and annual water consumption summaries for the whole-building and subsystem water meters?

If a building’s meter or submeter was installed less than a year ago, how can we provide monthly and annual summaries?

The water utility for the project building supplies electronic readings of whole building water consumption at least weekly that the project team can access. Will the electronic readings suffice for the required documentation for WEc1?

We own our water meters and the manufacturer of the submeter does not provide documentation recommending a calibration interval. How can we document that we’ve met the calibration requirements?

For meters not owned by a third-party, when should the meter calibration take place in order to comply with WEc1?

EBOM-2009 WEc1:Water Performance Measurement

Option 2: Process Water

My manufacturing facilty has more than one kind of process type water user, and they are very distinct. LEED says "Meter at least 80% of expected daily water consumption for process type end uses," (pg 93 LEED Reference Guide EBOM 2009). I'm wondering if this means if I have to meter 80% of all of my process waters or just 80% of one type of process water? For example: One process use is for cleaning parts and another is for coolant. Do I have to do 80% of both combined, or could I just do 80% of the coolant system?

It's 80% of ALL the water that is going to process...not each process...HOWEVER I would suggest that you do sub-submeter each individual process water use as well. There is a long list of options for re-use of process water that can significantly reduce potable water use. (Potable water initial use for cleaning parts, re-used a second time for cooling, reused a third time for flushing or irrigation) By sub-submetering the ROI can be clearly explained to the 'boss' .
