The module “M1, Overarching EPB standards” comprises the EPB standards and accompanying technical reports that deal with the overall energy performance of the building.

The overarching EPB standards provide basic information needed in  the standards covered by the other modules (M2 through M11), such as common terms and symbols or common choice of climatic conditions. And/or they provide procedures how to combine information from these other modules to aggregate into the overall energy performance data, such as the overall primary energy performance.
