Abstract

In our study, estimates are made for the distribution of the Hungarian residential real estate stock in 2020 by energy characteristics. In our calculations, which are novel in Hungary, a new database has been compiled by combining the energy certificates issued since 2016, the 2016 Microcensus and the housing construction statistics of the HCSO. Energy performance certificate data are assigned to the dwellings included in the Microcensus and to the 68,000 new dwellings built in the period since then. A statistical relationship is established between the characteristics and the energy demand of dwellings, which is then extrapolated to the stock as a whole. This is processed to present the estimated calculated energy consumption per square metre of the Hungarian residential real estate stock and the characteristics of the estimate by area and real estate type. Our results can support sustainable mortgage lending in the financial system.
