Energy efficiency of industrially made buildings influenced by thermal properties of façades

Abstract

The main objective of this paper is to evaluate the thermal properties of existing residential buildings built in industrial manner in Novi Sad, Serbia, from 1960 to 1990 based on building typology. Each of three analyzed building types has its characteristic façade, with thermal performances divided into periods according to the development of domestic thermal protection building codes. The necessary layer of subsequent insulation is determined by calculations in order to comply with European standards, also applied in Serbia from 2012. The proposed method of periodization simplifies the process of thermal performance assessment and it was checked through the case studies. Evaluation of energy consumption rationalization has been done through comparative analysis of energy losses. Based on the most common energy rehabilitation measures applied in Serbia, it was estimated that it was possible to reduce the energy losses in heating up to 60%.
