In the developed world, global warming represents a significant challenge, confronting humanity with the need for urgent and effective measures to reduce carbon emissions and sustainable use of resources. In the existing scientific articles on the issue, there is a lack of data from specific studies on the possible technological solutions in various climatic and geographical regions. It is necessary to specify the technical parameters and the corresponding engineering solutions to improve energy efficiency and reduce carbon emissions. It is particularly important to pay attention to the building sector, which currently consumes more energy than any other area. In order to mitigate climate change and achieve sustainability in the urban environment, it is essential to reduce the energy consumption of buildings. In the context of mass urbanization, especially in developing countries, where rapid urban growth exacerbates energy challenges, there is a growing need to develop effective strategies. This report proposes a solution to reduce energy consumption in residential buildings, leading to their designation as near-zero consumption buildings. Given the global scale of climate change and resource scarcity, improving global energy efficiency is becoming increasingly important. The European Union (EU) directive on the energy performance of buildings requires the renovation of at least 3% of the total built-up area of buildings and near-zero energy buildings. (nZEB) in all EU Member States by 2027. Some of the problems caused by these transformations are analyzed in this report.
