PASTATO IŠORINIŲ ATITVARŲ APŠILTINIMO TIKSLINGUMAS 2E RODIKLIŲ POŽIŪRIU.

The paper analyses the insulation expediency of the external envelopes of the building with reference to 2E (energy - primary energy consumption and environmental - CO, emissions) criteria and presents an overview of thermal insulation and studies on other structural elements based on life cycle analysis. The object of research is a typical residential building. The article determines different insulation materials of external envelopes, primary energy consumption and CO, emissions by insulating walls from F to B and from B to A ++ class. Graphical interpretation shows primary energy, CO, and the payback period of 60 years. Also, the paper considers primary energy and CO, emissions distributed at various life cycle stages.
