Energy intensity of a building in the process of estimating the market value of a residential unit

Abstract

Under current Polish legislation, the valuation of real estate should take into account the results of energy performance certificates and indications of for potential improvement of this performance which are economically viable and technically achievable. The Polish market of energy certificates is young. However, there are energy-intensive data that can be included in property valuation in the absence of energy performance certificates, especially in the case of residential units. The article proposes a way to assess the multi-family building's and its individual units' energy performance on the basis of information such as the location of the unit in the building, the consumption of heating units, the unit's (its living room's) sun exposure. Based on the analysis of the local real estate market (selected homogeneous housing estate in Szczecin), statistically significant relationships between the transaction price of a flat and its pricing features were sought, in particular those characterizing the energy intensity parameters of flats and buildings. The research is devoted to the current and important problem of including energy values in property valuation, but first of all it is important to improve the awareness of buyers and real estate professionals about the costs of heat energy and their impact on sustainable development.
