Due to the increasing climate changes and pollution, it has become inevitable to turn to a sustainable way of life, and this is exactly what has promoted the energy-oriented technologies and systems offered by the smart home through environmentally sustainable dimensions. This paper shows how the construction of a smart house can be associated with a sustainable way of life. The concept of sustainability is closely linked to numerous components of a smart house in the form of renewable energy sources, the use of closed-loop heating and cooling systems, and various forms of automation. The smart home system operates on the principle of reducing the consumption of energy and other resources to the lowest level, meaning that the same resources are used only as much as necessary. In addition, a smart house offers several benefits that facilitate the daily life of its residents, as its functionality, safety, efficiency and adaptability to needs make living in it easier and more comfortable. Although the initial investment in building a smart home is higher than in building a traditional home, the goal of a smart home is to reduce operating costs through efficient energy management, thus recouping the initial investment over the years. Thus, a smart house system that has high energy efficiency contributes to the preservation of the environment as one of the most important elements of sustainable development.
