Refurbishment of post-war prefabricated multifamily buildings

Abstract

Several suburban settlements had been built in Belgrade after the World War II. In that time, a few prefabricated systems were mostly in use in our country which resulted in housing settlements consisting of numerous buildings with the same or similar layouts. They are all characterized by poor energy performance causing high energy consumption (for heating and cooling) and CO2 emissions. One of the examples of such architecture is the Konjarnikhousing settlement. Different scenarios-hypothetical models for the energy performance improvement of the envelope of the central block of the prefabricated multifamily building in Konjarnik are created. The design of improvements of the envelope of the existing buildings is created according to Belgrade’s climatic conditions, building orientation and technical characteristics of the building structure.The assessment of the reduction in energy consumption for space heating and thus the reduction of CO2 emissions has been carried out in the paper. Methodological approach entails the following steps: creation of models of the improvement of existing buildings, consideration of the results of thermodynamic simulations of energy performances of the modelsin terms of energy consumption and CO2 emissions, and comparison of the results (models).
