Methodology for Residential Building Stock Refurbishment Planning-Development of Local Building Typologies

This paper presents the methodology for the implementation of building typology principles as a tool for the strategic planning of residential building stock energy retrofits on a municipal level in Serbia. Research was conducted under the IEE EPISCOPE (Intelligent Energy Europe EPISCOPE/TABULA project) project with the aim of developing an adequate tool for creating building stock energy retrofit management strategies on a local level. An approach that envisions the diversity and uneven spatial distribution of building stock in smaller scale municipalities and includes statistically relevant sampling of all relevant building types was developed and tested in the pilot project that focused on the city of Vrsac. Two options for local typology development were formulated: a top-down approach, which relies on the data from the national typology or other available databases by reducing them to the local level, and a bottom-up approach, which represents a new data gathering and processing method. Both approaches were tested in the pilot project and the results are compared in this paper. From the conclusions of these analyses, a common methodology for the development of local building typologies has been defined. It can be used in the strategic planning of building stock, whether for the purpose of developing local energy action plans (LEAPs) or other purposes internationally.
