FAQs about WEc4 :

Are there any requirements for the frequency of meter reading/recording?

If a building only has one of the required systems, is it enough to submeter that one or are you not eligible for the credit at all?

NC-v4 WEc4:Water metering

WEc Water Metering

I am working on a homeless shelter project with three large water uses: kitchen, laundry, bathrooms (toilets, sinks & showers) where toilets are on cistern water. I am wondering if the project can earn the WEc Water Metering credit by monitoring hot water, which would include the showers, kitchen and laundry. A water softener has a flow meter that is built in. Would this count? Does the water mete have to be connected to automation or is analog ok?

Hi Theresa, submeters may be manually read and do not require connection to an automation system. I believe a built in flow meter on the water softener that is able to provide the amount water consumed for domestic hot water use would contribute to credit compliance.  If the water softener serves both cold and hot water, I would expect that the project would need to provide a meter for the hot water usage only; in addition to the built in flow meter of the water softener.  Hope this helps!
