Our meter is owned by a 3rd party, the local utility company, it is an electronic meter, however, they only take the reading monthly. On the bill it breaks out average daily usage, how many days, etc. If I transfer this information to a spreadsheet can it be used for this credit?

Sorry Kimberley, that won't work. The intent of the credit is to ensure that meters are read regularly enough to catch leaks and unexpected consumption quickly, and with enough granularity to identify unusual patterns. USGBC has decided that a weekly reading is the right level; breaking monthly numbers into weekly averages isn't sufficient.
Hope that helps,
Dan

Yes for submeters, and in fact all meters (energy, water et al) weekly direct reading (real time or written) is by far the better method. However a small wrinkle has just be printed in the new Recertification guidelines (dated November 1, 2012) This states that for water performance metering-whole buildings (WE c1.1):
“Maintain continuous manual or data–logged meter readings. In the application, provide at least monthly meter readings from the most recent 25% of the recertification performance period.”
This is then changed for Water Performance measurement-sub metering (WEc 1.2)to:
“Maintain continuous manual or data–logged meter readings. In the application, provide at least bi–weekly meter readings from the most recent 25% of the recertification performance period.”
Neither of these ask for weekly readings which confuses the situation no end, but I support Dan’s position that ‘granularity is the key” and weekly does have one’s finger on the pulse of water usage.
