Energy optimization of the building envelope of the representative sample of the existing residential building in Banja Luka

Abstract

The primary task of this paper is to present to the scientific and professional community the application of regulations in the field of energy efficiency of Serbia and Croatia, based on the specific example of a representative sample of the building envelope of the existing residential building, in the climatic conditions of the city of Banja Luka (Republic of Srpska, Bosnia and Herzegovina). It will be pointed out to the adequate settings of a limit for maximum U-values (limit for maximum thermal transmittance values) for the elements of the building envelope, in order to comply with specific heat transmission losses in relation to the factor of building form (A/V ratio) for residental buildings, in case of refurbishment of entire envelopes of existing residential buildings, as well as in case of building new ones. This paper presents the analysis of energy savings and costs of measures applied to the energy optimization of the building envelope on the representative sample of the existing residential building in Banja Luka.
