Enhancing Building Energy Efficiency through the Implementation of Renewable Energy Sources

Abstrakt

Considering increasing sustainability requirements and the urgent need to reduce greenhouse gas emissions, improving the energy efficiency of buildings has become a key challenge in the construction sector. One of the most promising approaches involves the integration of renewable energy sources (RES) as alternatives to traditional, high-emission energy systems. This paper presents an analysis of the potential for using RES—such as solar, geothermal, and biomass energy—to enhance the energy efficiency of residential and public buildings. The economic and environmental benefits of implementing modern energy technologies are discussed, along with examples of technical solutions and hybrid system models. Legal, technical, and social aspects related to the implementation of such systems are also considered. The results of the analysis indicate that well-designed and properly managed RES systems can significantly reduce the demand for primary energy and CO₂ emissions while increasing the energy independence of buildings.
