WEp1: Water Use Reduction Additional Guidance, version 8, Updated 4/1/2013

The guidance has been updated to clarify that the blow-out fixture guidance is only available to rating systems that include blow-out fixtures in the prerequisite requirements (not EBOM), and to include the 0.25 gpc baseline for the metering type / autocontrol lavatory faucet in footnote 2 of Table 1 Non-residential Default Fixture Uses to align with the 4/1/2013 Addendum which clarified that the autocontrol lavatory faucet baseline is 0.25 gpc for the baseline case.
