Economic effectiveness of systems wiring

This master’s thesis tries to show the differences between usual obsolete indoor wiring and clas-sic indoor wiring used these days and also between this „classic“ indoor wiring and „intelligent wiring“. There is insisted on selection and optimalization of the adequate system for a concrete building and there is made a question of specifications of the user or the customer, his preferen-ces (financial, space, family etc.), disadvantages and advantages of the current system. Whereas it’s impossible to satisfy all the users in these problems by reason of diversity of the buildings (it can be a lot of variants of family houses or small apartments), the systems in this thesis are ap-plied only on the most frequent types of houses. Quite lot of firms deal in this country with indo-or wiring, the most known are ABB, ELKO EP and Moeller. Each of these firms offers different alternatives of systems. From the simplest, basic alternative, to most sophisticated „intelligent“ systems, which can care about almost everything, what is common with electrical energy. These different systems, their review, advantages and disadvantages are also presented in this work. Preliminary there is analysed the whole issue from the historical view and there is briefly explai-ned, what the system wiring is. In the next chapter there is a complex description of the actual state of known firms and systems on the present-day market in our country and in the world. The-re is also summarised the basic structure and the overall comparison of the most frequently used bus systems. In the next two chapters there are presented the main objectives of this work and the methods and procedures, how to achieve these objectives. The central part of this work is the next to last chapter, in which there are presented the different model variants of the project, applied to the real residential building - middle-sized family house. That is realized on the basis of the spe-cified requirements on the designed system. Before that there was performed the complex design of the situation scheme of all usual electrical appliances and lighting system in the house. In the end the whole work is in summary analysed, mainly in term of costs of each variant of the pro-ject. By virtue of this can the reader make a better view about the whole financial problem of the system wiring, that means, how much he has to invest in his concrete wiring. In the end of the work there is attached the detailed documentation to all alternatives of the project, such as dra-wings (complex horizontal plans) and costs budget of all used items and the wiring material
