Abstract: The present study focuses on the modeling and simulation of the Ukrainian residential building stock. The aim of this research is to evaluate the gas demand for different end-uses such as space heating, domestic hot water and cooking, at a local, regional and national scale. The proposed building stock model is developed using a Modelica based low-order building model calculation engine. A bottom-up approach is then applied to obtain and parameterize the building stock model by using data from several Ukrainian organisms, such as the State Statistics Service of Ukraine. The building stock model is able to run for a whole year, by taking into account when to operate in heating or non-heating modes, and with the possibility of combining space as space heating, domestic hot water and cooking. Various occupancy profiles were defined and different building archetypes were considered (individual and collective buildings) with several thermal performance levels. Four different regions and climate zones were considered, based on the Ukrainian climate, and the results are presented for all cases with regards to the different local characteristics.
