Refurbishment of the existing multi-family housing stock from the period of post-war mass construction: spatial and energy benefits [predavanje po pozivu]

Abstract

The most represented multi-family housing stock within the cities of Serbia was built in the period from 1946 to 1970. 25% of the total multi-family stock of Serbia consists of buildings built in that period. This multi-family housing stock is at the centre of discussion due to its energy, functional and spatial-organisational obsolescence. Designed with the aim of providing apartments for as many people as possible in the short term, these buildings are characterised by small apartments, outdated and rigid spatial organisation, inadequate dimensioning of spatial units and small window openings on the facades. In addition, these buildings have a high energy consumption for heating. The subject of the research includes the analysis of the application of complex and integrated refurbishment by adding exoskeleton to existing multi-family buildings in order to achieve high energy effi ciency of buildings and increase the space of residential units, as well as improve vertical communications of buildings. The exoskeleton represents a spatial structure that is added to the existing building with the aim of spatial-functional and energy improvement. The paper will present various possibilities for the position of the exoskeleton on the envelope of the existing building, based on which it can be determined which spatial-organisational and functional characteristics of the existing building are being improved. Based on the predetermined typology of residential multi-family buildings, a classifi cation of possible positions of the exoskeleton on the envelope of each type of multi-family building will be made. The goal of the research is to review the advantages and limitations of exoskeleton application in different types of multi-family residential buildings and to determine the possibilities of improving the spatial-organisational, functional and energy performance of existing multi-family buildings by applying complex and integrated refurbishment using exoskeleton.
