The smart home concept revolves around integrating technologies to enhance the efficiency, comfort, and security of a residential building or unit. While smart home applies to individual households, smart building refers to larger structures like office buildings and industrial facilities. Smart home technologies primarily focus on automation and connectivity for devices and systems within a private residence. This allows for remote and demand-based control of household appliances, heating and cooling systems, and lighting. Users benefit from personalized settings tailored to their preferences, leading to increased comfort. Smart home technologies also enable real-time monitoring of energy consumption in smaller units, helping identify potential savings. These systems are typically less complex than those used in commercial buildings and often operate in isolation. Therefore, the smart home is designed for private users. Both smart home and smart building concepts enhance a building's energy efficiency and generally result in cost savings, but they cater to different application areas and user groups.
