The research examined the environmental impact of listed and unlisted buildings from different periods. Compliance with strict standards encourages professionals and researchers to improve the environmental impact of buildings by examining the root causes of problems in more depth, which requires understanding and analysing the entire life cycle of buildings. People’s attitudes have changed, both in terms of raw materials and energy consumption. The article is a literature review of research published in recent years in the field of environmental impact assessment of historic (and in some cases younger) buildings. It analyses and summarizes the questions that researchers sought answers to, the methods they applied, the data and databases they used, the calculations they performed and the results they achieved. When collecting the analysed sources (research articles), the goal was to find sources presenting a large number of case studies. The case studies were classified according to geographical location; the historical age of the buildings and, in this context, the materials and structures used; the extent of the expansions, transformations and modernizations carried out. The literature review provides insight into the current state of science on how to quantify the value of historic buildings. Based on the experiences gained, it is also possible to formulate and conduct a domestic research. The article contributes to a deeper understanding of the calculation of the environmental impacts of historic buildings, which can help in compliance with legislation, energy and environmental requirements, and in the protection of existing buildings.
