This thesis deals with design and implementation of wireless system for automated control and monitoring of central heating. Some of the existing solutions and their characteristics are briefly introduced at first. The attention in this thesis is subsequently given to the analysis of wireless technologies and power supply methods suitable for home automation. With regard to ascertained findings, the design and subsequent implementation of system modules using Raspberry Pi, the ARM Cortex-M0+ microcontroller and the ZigBee communication modules were performed. The firmware for created modules was designed and implemented. The designed system can be controlled and monitored using a mobile application for the Android platform, whose design is also described in this thesis.

The primary energy costs of building materials and structures are discussed and comparisons are made between typical dwelling types. The economics of alternative wall, roof and floor constructions, providing various levels of insulationy are examined. Costs are assessed for a number of periods from 1970 to early 1980 for heating by gas and night rate electricity. The effect of price changes-on the economic attractiveness of insulation is investigated and the likely effects of future price rises are considered. It is concluded that, in certain circumstances, higher levels of insulation than those normally used in the UK have been economically attractive for the last few years and may possibly become more so. A survey of over fifty local authority houses with central heating, carried out by the author in Spring 1978, is described. Three types of houses of similar size were involved, having gas-fired 'wet' systems, and ducted warm air heating from electric storage and gas-fired units respectively. The survey was designed to determine certain aspects of occupant behaviour relevant to fuel consumption. Using regression techniques, relationships are obtained which explain more than two thirds of the variance of mean useful energy input rate between the houses of a given type in cold weather in terms of hours of use of central heating window opening habits, and for warm air heating, the closing of outlet registers. It was also revealed that for the house types with gas-fired heating the number of hours of use of the central heating was strongly influenced by household size and occupancy patterns. The implications for building design of the effects of occupant behaviour and of financial and energy costs are discussed.

Domestic gas consumption for central heating is a function both of the efficiency of the heating system and the way in which it is used. While many studies have concentrated on the performance of systems and their controls, there have been few studies of occupant behaviour. The thesis therefore studies household behaviour patterns relating to domestic gas consumption. There are two main aims: firstly, to study a variety of these patterns and, secondly, to make a detailed investigation of one particular behaviour pattern, namely window opening. These two studies centre on 113 households on two local authority estates, where all the dwellings are of similar construction. The first study makes use of two main data sources: quarterly gas consumption readings and data obtained from an in-depth interview with each head of household. It identifies a variety of behaviour patterns and their underlying motivations. Additionally, this study shows that design heat loss and terrace position account for less than a third of the variance in winter consumption. A regression analysis using only behavioural and social variables resulted in a similar proportion of variance being explained. These two sets of independent variables could not justifiably be combined due to their inter-correlations. In conclusion, it was suggested that consumption may not be determined by a few variables of major significance but rather by a large number of inter-acting variables each with a small influence on consumption. The second study, window opening, makes use of three data sources: a series of systematic window observations, meteorological data and data obtained from postal questionnaires. The study identifies the objective correlates of estate-wide window opening, as well as the subjective motivations for the opening and closing of windows. It highlights the wide range of variation in window opening amongst householders. In addition, the study indicates that householders adopt characteristic window opening patterns which they can reliably report.

In this thesis, I was solved assessment of nuclear power plant Dukovany, conection to the hot water network to city Brno. For determine the size needful enforcement was necessary to establish the heat balance of needs of the city of Brno and the size of the heat supply options. After that it was possible to determine the dimensions of pipes and optimize his routes of due to the current state of land along the route of thermal power supply. Power supply parameters were chosen with regard to the possibilities of technology used for transmission of the media and the status quo for distribution of the city Brno. After pushing the power supply ahead of the city Brno into the pumping station Bosonohy, and second part of the solution was the connection to the backbone wiring SCZT heat to individual customers. The last point was elaborated design management system of heat from nuclear power plant and urban local based resources on current management of heat supply system using consumption diagrams SCZT.

En jämförelsestudie har genomförts mellan två värmesystem. Analysen har genomförts med ett flerbostadshus som referensfasighet. Fastigheten är lokaliserad i Södertälje kommun. Analysen går ut på att bestämma vilket värmesystem som är fördelaktigt vid renovering av äldre flerbostadshus med avseende på energi och kostnad. De systemen som har behandlats är ett centralt värmesystem med motströmsvärmeväxlare och ett centralt värmesystem med frånluftsvärmepump. Det centrala värmesystemet (Eq aggregat) är ett centralt från- och tilluftssystem med återvinning (FTX system). Systemet använder en motströmsvärmeväxlare för överföring av värmeenergi mellan från- och tilluften. Det centrala värmesystemet (Energi well) är ett frånluftssystem (FX system) med en ny teknisk lösning. Systemet återvinner värme ur frånluften med hjälp av kondenserande frånluftsvärmpumpar. Värmepumparna finns i en frånluftskammare på vindsvåningen. Den återvunna värmen förs sedan vidare till undercentralen för att värma upp varmvattnet. Analysen har genomförts med hjälp av teoretiska energi- och kostnadsberäkningar, intervjuer och faktainsamlingar.  Energiberäkningarna har bestått av en energibalansberäkning för att få fram den köpta energiförbrukningen. Kostnadsberäkningar har bestått av en livscykelkostnads kalkyl och en kostnads beräkning per producerad värmeenergi. De resulterande värdena för båda värmesystemen har sedan jämförts med varandra. Resultatet visade att värmesystemet Energy well var mest fördelaktig ur både energi och kostnad perspektiv. Den årliga köpta energiförbrukningen var                          lägre än värmesystemet (Eq aggregat) med en motströmsvärmeväxlare. Driftkostnaden var  lägre än Eq aggregat, installations-kostnaderna var  lägre än Eq aggregat och slutlig var livscykelkostnaden  lägre än värme-systemet (Eq aggregat) med motströmsvärmeväxlare. Men underhållskostnaden var  högre än värmesystemet Eq aggregat. Slutsatserna för de teoretiska undersökningarna gav bättre värden för värmesystemet Energy well. Vilket innebär att Energy well är mest fördelaktig utifrån energi- och kostnads perspektiv. Däremot ger värmesystemet med motströmsvärmeväxlare en lägre risk att ett driftfel inträffar i verkligheten. / A comparing study between two different heating systems has been accomplished. The analysis has been conducted with an apartments building as a reference project. The building is located in the municipality of Södertälje. The goal of the analysis is to determine which of the heating system is beneficial for older apartment buildings in terms of energy and cost. The systems that have been treated are a central heating system with a counterflow heat exchanger and a central heating system with an exhaust air heat pump. The central heating system (Eq unit) is a central exhaust- and supply air system with heat recovery. The system uses a counterflow heat exchanger to transfer the heat energy between the exhaust- and supply air. The central heating system (Energy well) is the latest technical solution of a central exhaust air system. The system recovers heat from exhaust air by condensing exhaust air heat pumps. The heat pumps are in an exhaust air chamber and it´s placed on the attic floor. The recovered heat energy sends then to the mechanical room to heat up the water system. The analysis has been accomplished by using theoretical energy- and cost calculations, interviews and data collection. The energy calculations are based on an energy balance equation to determine the bought energy consumption. The cost calculation is based on a life cycle cost equation and a cost equation per produced heat energy. The results of both heating systems have been compared with each other. The results showed that the heating system Energy well was most beneficial in both energy and cost perspective. The annual consumption of bought energy was                          lower each year than the heating system (Eq unit) with a counterflow heat exchanger. The operating costs of the system were  lower than Eq unit, the installation costs were  lower than Eq unit and final was the life cycle cost  less than the heating system (Eq unit) with counterflow heat exchanger. But the service cost was  higher than the heating system Eq unit. The conclusion of the theoretical investigations gave better values ​​for the heating system Energy well. This means than Energy well is most beneficial from the energy and cost perspectives. Contrariwise has the heating system with counterflow heat exchanger a lower risk of an operational failure to occur in reality.

Sur un exemple concret d’entreprise française disposant des technologies innovantes dans les domaines du chauffage et de la distribution d’eau et ayant un projet d’expansion vers un nouveau marché, en l’occurrence, le marché russe, l’auteur montre l’importance de ces technologies pour accéder au marché fortement différent du marché domestique. Au sein du secteur du chauffage dans un pays où, à cause des conditions climatiques froides, le besoin de se chauffer présente un besoin vital, où le retard technologique dû au phénomène historique du monopole du chauffage central collectif est particulièrement ressenti et où le marché est en pleine formation avec la montée de la concurrence, les technologies nouvelles ont sans doute un rôle capital à jouer. Comment l’entreprise porteuse de ces technologies doit-t-elle aborder le marché russe certes très prometteur, mais fragile surtout en cette période délicate de la crise économique mondiale? Quels en sont les risques et les perspectives ? Comment réussir ce marché ? Comment mettre en valeur et transférer de nouvelles solutions technologiques ? Quels sont les avantages de ce transfert pour l’entreprise, mais également pour son partenaire local, pour la région visée et pour l’Etat receveur ? Telles sont les questions que l’auteur se pose. Le rôle des technologies nouvelles va certainement au-delà d’un secteur ou d’un domaine d’activité : les technologies nouvelles apportées par des entreprises occidentales ont sans doute accéléré, en ce qui concerne la Russie, le passage d’un système économique du type soviétique vers un système de libre-échange que l’on connait sous le terme d’économie de marché. / On a specific example of a French company having innovative technologies in the field of heating and water distribution, and realizing an expansion project to a new market, in this case, the Russian market, the author shows the importance of technologies when penetrating a market strongly different from the domestic one. Within the heating sector in the country where, because of a cold climate, the need to feel warm is a vital need, where the technological backwardness due to the historical phenomenon of the central residential heating monopoly is obvious, and where market is taking shape and competition is now growing, new technologies have without doubt a capital part to play. How should a company with such technologies approach the Russian market certainly very promising, but also fragile especially in this delicate period of the world economic crisis? What are the risks and the perspectives for the company? How to succeed in this market? How to enhance the value and to transfer new technological solutions? What advantages does this transfer bring to the company, but also to the company’s local partner, to the targeted region, and to the receiving country? These are questions the author asks himself. The role of new technologies is certainly beyond a sector or a field of activity: the new technologies brought by western companies undoubtedly accelerated, as Russia is concerned, the change from the Soviet-type economic system to a free-market system, known as the market economy.

The import of the vegetable has prevailed in the long run over the own production. In connection with this reality and increasing demand for the food with higher quality the production greenhouse is more often built. The providing heat, cold and electricity for the year-round operation is related to the construction and working of these objects. The theoretical part of this theses describes possible ways how to cover energy consumption for the model greenhouse in Kožichovice, Třebíč region. The heat losses and the year-round heat consumption were stated for the selected model and compared with the exact values from Kožichovice. The following method of energy supply was selected based on the calculated energy consumption - the separate cogeneration unit, cooperation of several cogeneration units, a biogas station, a heat pump and central heating system. These methods of energy supply were subjected to technical and economical comparison.
