Abstract

Green behavior and the desire to act sustainably are two perspectives that are extremely important from an environmental point of view. In the realm of mortgage products, there has been a significant emphasis on the environmental aspect of environmental, social, and governance considerations. One area where we can act in this way is the property market. Here, energy performance certificates (EPCs), which determine the energy class of a building, play an important role, especially from the point of view of banks. Banks see the contribution of EPCs as an added value in assessing the riskiness of a building, which has a major impact when we talk about lending, investments, and other banking aspects. In our research, we tested twenty-eight different models, looking for the one that would classify buildings into energy classes as accurately as possible. The bagged trees model proved to have the best classification power, achieving 72.4% accuracy.
