In Directive 2012/27/EU, as amended by this Directive, a statistically significant proportion and representative sample of the energy efficiency improvement measures should be understood to require the establishment of a subset of a statistical population of the energy-saving measures in question in such a way that it accurately reflects the entire population of all energy-saving measures, and thus allows for reasonably reliable conclusions regarding confidence in the totality of the measures.
I dTreoir 2012/27/AE, arna leasú leis an Treoir seo, ba cheart a thuiscint le sciar mór ó thaobh staidrimh de agus sampla ionadaíoch, ó thaobh staidrimh de, de na bearta feabhsaithe éifeachtúlachta fuinnimh gur gá fothacar de líon staidrimh de na bearta coigiltis fuinnimh atá i gceist a bhunú ar shlí a léiríonn go cruinn iomlán na mbeart coigiltis fuinnimh, agus, ar an tslí sin, go gceadaítear tátail réasúnta iontaofa a bhaint maidir le muinín as iomlán na mbeart.
