As a non-us consultant I always have a problem attending the EA.P2 requirement. ASHRAE 90.1-2007 item 7.4.2 requires that all water heating equipment meet the criteria listed in the table of "Performance Requirements for Water Heating Equipment" (table 7.8). This table bring water heating equipment efficiency in only US test procedures, like DOE 10 CFR or ANSI Z21.10.3.
Does my non-US (Brazilian) project has to attend to this efficiency or can I attend a local water heating equipment efficiency? (none of the Brazilian or even European equipments test their products using these american procedures).
Thank you in advance!

You are required to demonstrate that the local efficiency is similar to the US efficiency. They are not required to use the US testing procedure. Typically the equipment manufacturer can help.
