Energy management in households as part of the sustainable development of the energy economy

The increasing demand for comfort, security and energy savings in modern buildings, combined with the development of electronics and information technology, has contributed to the design of modern systems supporting management in building installations. This article addresses the issue of controlling modern electrical installations using computer-aided design and programming. One of the methods used is the use of visualization. It is the basic element informing the user of the system about the state of individual objects included in the building automation, which enables it to communicate and influence the controlled objects. Smart meters become an important part of building automation systems. These systems are commonly referred to as smart electrical installations. It is intended for switching, controlling, regulating and supervising equipment located in a building. For communication between the components, special communication protocols such as KNX, CAN, ZigBee are used. Their characteristic feature is the separation of power supply circuits from control circuits.
