If (a part of) a table in Annex A of the EPB standard is not applicable due to national choices that are in line with the standard, the corresponding (part of) the table in the National Annex or National Datasheet may be left blanc. It is strongly advised be stated explicitly why (the part of) the table is not filled in. For example:
- Case 1: table An EPB standard offers a choice between two methods (e.g. simplified or detailed, monthly or hourly time interval). If the national choice only allows one of the methods, then all tables about the other method are irrelevant and may be kept blank. In this case an explanatory note should be placed in or below these tables, for example: “According to Table NA.xx the national choice is for Method A. Tables A.xx – A.yy are only relevant for Method B.”.
- Case 2: Some tables are intended to offer the possibility to specify (national or regional and typically ‘conservative’) default values, in case project specific data are not or not yet available. If the national choice is not to provide default values, then the table may be left blank. In this case, an explanatory note should be placed in or below the table, for example: “No default choices: the choice is project dependent”.
