Advantages of energy efficiency in upper-story apartments: integration of photovoltaic systems and smart home technologies

In the context of accelerated urbanization and rising energy prices, apartments located on the upper floors of urban buildings often face disproportionately high cooling and heating costs due to increased exposure to natural elements and energy inefficiency. Building-integrated photovoltaics have been driven by technology and policy to evolve and become a widespread technical solution. This technology makes it possible to transform a building from an energy-consuming to an energy-producing facility [1]. The smart home system plays a crucial role in this integration, optimizing energy consumption in real time, efficiently managing available energy resources, and maximizing the energy autonomy of the apartment. Home energy management system (HEMS) is crucial for real-time monitoring and implementation of renewable energy sources, permitting a greater application of green energy while raising the advantages of capital investments [3]. Through advanced machine learning algorithms and automation, this system allows not only better adaptability to the user's consumption profile but also proactive interaction with the urban electrical grid infrastructure. This study analyzes the market to evaluate the viability and economic impact of implementing the proposed technologies, offering a replicable model for the energy transformation of urban dwellings. Preliminary results indicate a significant reduction in energy costs and an increase in residential comfort, promoting sustainability and energy efficiency at the urban community level.
