Purpose. The main purpose of the study is to create energy-efficient solutions when designing the lighting of the entrance group for the case when the object must provide round-the-clock operation Methodology. To achieve this goal, a method for multi-level connection of light sources of different intensities has been developed. The control of the processes of level regulation is carried out using motion sensors. Results. The modern level of LED products makes it possible to use LED lighting sources as universal ones, allowing you to implement any design solution. The introduction of motion sensors as elements for regulating the intensity of light allows to obtain more than 50% energy savings. Interesting design solutions help create light accents without creating too much lighting on certain objects. Scientific novelty. The work combines multilevel lighting systems using motion sensors as switches operating at night. The authors proposed a sequence of connecting the levels of the system to create the most comfortable stay and a good first impression of the institution. Such a system makes it possible to use lighting not only for practical purposes, but also for the most attractive visual appearance. Practical significance. The versatility of this methodology allows it to be applied to objects of various purposes, including round-the-clock service. However, it is important to plan for such a lighting system even at the design stage of the building in order to obtain the maximum economic benefit. [ABSTRACT FROM AUTHOR]

Purpose. Development of a software complex for increasing energy efficiency of the city district due to implementation of optimal energy saving measures. The article considers the problem of increasing the efficiency of use of fuel and energy resources in Ukraine, rational use of energy in energy resources is justified, because the existing energy saving potential is quite large. Methodology. The article uses the system-structural approach to solving the energy efficiency problem of a separate energy consumption area of the city. As a mathematical apparatus, a rank analysis is used, which refers to the method of researching the technocenosis of energy consumption, which implies further optimization based on the criteria of the form of hyperbolic H-distributions. Results. The program "Smart Technocenosis" is presented for optimization of technocenosis energy consumption of the city district on the example of Solomyansky district of Kyiv, which is intended for analysis and increase of energy efficiency of energy consumption of objects of the budget sphere. Also, an example of calculations on the electricity consumption parameter made on the basis of the software system is considered. Originality. It was developed and proposed to use the software complex "Smart Technocenosis" to calculate the potential of energy saving and detect abnormal objects for the consumption of electric energy, thermal energy and gas. Practical significance. When using the "Smart Technocenosis" software program in the areas of energy saving in the city of Kyiv it is possible to achieve reduction of consumption of energy resources by objects of the budgetary sphere, reduction of expenses for fuel and energy resources and increase of comfort level in buildings of budgetary sphere with observance of sanitary-hygienic norms.
