U radu se daje osvrt na najbitnije razlike u nacionalnim regulativama koje definišu oblast energetske efikasnosti zgrada, u Srbiji, Makedoniji, Crnoj Gori i Albaniji, dakle na tržištima za koje je objavljen softver „KnaufTerm2“, u verzijama programa prilagodjenim lokalnim osobenostima, i to sa aspekta energetske sertifikacije, dozvoljenih vrednosti koeficijenata prolaza toplote i tretmanu linijskih transmisionih toplotnih gubitaka.

The paper provides an overview of the most important differences in national regulations that define the area of energy efficiency in buildings, in Serbia, Macedonia, Montenegro and Albania, countries for which software "KnaufTerm2" is released, in versions adapted to local characteristics, in terms of energy certification, allowable values of the coefficient of heat transfer and the treatment of linear transmission heat losses.
