The subject of the thesis is a technological and economic analysis of three ways of lighting control in a hotel. In all larger catering and public facilities, it is in the owner’s interest to have as little electricity consumption as possible, since energy efficiency is one of the basic requirements for a building. It is important that the use of lighting in the exploitation of the facility is as simple as possible. This paper will analyze three ways of lighting control in a hotel: 1. DALI control 2. Control of relays, sensors, timers and programmable relays 3. Classic control For each of the three control methods, the complexity of the design, the complexity and time of execution, the cost of execution and the price of equipment, and the ease of use as well as the possible return on investment with smart control will be analyzed.
