The article provides an overview of the most pressing issues arising from the widespread use of LED lamps in buildings and structures. This work is a precursor to a series of articles devoted to research in this field. The features of operation of electric lamps currently used in lighting systems are considered. The influence of lighting quality on human health and the effect of lamps on the electrical network is shown. The radiation spectra of lamps and their key difference from the natural solar spectrum are considered. The article presents the influence of the nature of the nonlinearity of the load of electric lamps on the quality of the power supply network and its individual components. The characteristic of the service life of energy-saving lamps is given.

The problems of building human-machine interfaces of automated operational dispatch control systems with a high density of information flow are considered. The article is devoted to the modernization of the graphical part of control systems with the proposal of levels of graphical mnemonic circuits and their description of their advantages. In the second part, the modernization of the previously proposed algorithm for the development of an alarm subsystem is given. The advantages of the proposed approaches for the end user are derived.

Based on the experience gained during the use of Autodesk Revit in the design of power supply systems, the authors assess the features of the implementation of the construction of projects in this section that meet domestic regulatory documentation. A comparative analysis of the methods of constructing power supply projects is given, their advantages and disadvantages are revealed, which is important both from a scientific and practical point of view with a small amount of information in this area that does not have an advertising component.

The modernization of the algorithm for creating a user (human-machine) interface of automated operational building management systems is proposed, which allows creating more efficient means of information output. The problems of creating modern production interfaces are analyzed. Modernization includes, in addition to the traditional way of creating the interface itself, taking into account the nature and working conditions of the people using it and other factors.
