Sustainability is understood in a broad sense, involving among others, the economic, social, environmental and cultural as well as the habits and customs rooted in the resident population. Just a few examples of practical application and little literature on the deployment of technologies for energy savings in social housing, especially from the standpoint of sustainability and adaptation of the population to new technologies. To this end, we seek to identify the impacts generated by the insertion of solar collectors in social housing, produced by MG-COHAB (Housing Company of Minas Gerais) Homes Program - Housing in small towns in Minas demographic General, assessing the appropriateness of incorporating solar collectors to the habits and customs of the population and possible changes in behavior resulting from the presence of this new technology into living space. We conducted three case studies, the Homes of Mercy of Caratinga, Itatiaiuçu and Dores de Campos. It was conducted in each housing a Post-Occupancy Evaluation Behavior gauge user satisfaction with respect to the installation of solar water heaters in homes. As main results we have: user satisfaction with the financial savings generated by the solar heater and the comfort afforded by the increase of the length of the shower, due to carelessness in terms of energy consumption, lack of regular maintenance of the system solar heating by the residents, the discrepancy between the use of solar heating and reduced environmental impacts. We conclude that despite the positive impacts related to economic and cultural sustainability, residents do not relate to use of solar technology with sustainability and therefore the incorporation of solar collectors is not sufficient to create an environmental awareness. These results show that the act of incorporation of the solar heater in social housing by COHAB-MG represents important social gains, but must be accompanied by an awareness campaign in order to extend the benefits to the population, characterized as an important step towards a balanced social housing, for sustainability. / Neste trabalho propõe-se uma investigação acerca da implantação do sistema de aquecimento solar de água na habitação de interesse social, sob o ponto de vista da sustentabilidade da tecnologia adotada. Entende-se a sustentabilidade num sentido amplo, que envolve entre outros, os aspectos econômicos, sociais, ambientais e culturais bem como os hábitos e costumes arraigados na população residente. Ainda há poucos exemplos de aplicação prática e pouca literatura sobre a implantação de tecnologias visando à economia de energia na habitação de interesse social, sobretudo sob o ponto de vista da sustentabilidade e da adaptação da população às novas tecnologias utilizadas. Para tanto, busca-se identificar os impactos gerados com a inserção de coletores solares na habitação de interesse social, produzida pela COHAB-MG (Companhia de Habitação de Minas Gerais) no Programa Lares - Habitação Popular, em cidades de pequeno porte demográfico em Minas Gerais, avaliando a adequação da incorporação dos coletores solares aos hábitos e costumes da população e possíveis mudanças de comportamento decorrentes da presença dessa nova tecnologia no espaço habitacional. Foram realizados três estudos de caso, nos conjuntos habitacionais de Piedade de Caratinga, Itatiaiuçu e Dores de Campos. Efetuou-se em cada conjunto habitacional uma Avaliação Pós- Ocupação Comportamental para aferir a satisfação dos usuários com relação à instalação do aquecedor solar nas habitações. Como principais resultados encontrados têm-se: a satisfação dos usuários com a economia financeira gerada pelo aquecedor solar e com o conforto propiciado pelo aumento do tempo de uso do chuveiro, decorrente da despreocupação em relação ao consumo energético; a falta de manutenção periódica do sistema de aquecimento solar pelos moradores; a desvinculação entre o uso do aquecimento solar e a redução dos impactos ambientais. Conclui-se que, apesar dos impactos positivos relacionados com a sustentabilidade econômica e cultural, os moradores não relacionam a utilização da tecnologia solar com a sustentabilidade e, portanto, a incorporação dos coletores solares não é suficiente para criar uma consciência ambiental. Esses resultados mostram que a ação de incorporação do aquecedor solar na habitação de interesse social pela COHAB-MG representa importantes ganhos sociais, mas deve ser acompanhada de um trabalho de conscientização com a finalidade de ampliar os benefícios concedidos à população, caracterizando-se assim como um importante passo na busca de uma habitação social equilibrada, em prol da sustentabilidade.

The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.

The Master’s thesis discusses wireless thermostat for a control boiler. In order to complete the project we have to design and realise the whole project with software design. The system contains two units, a master control and a measurement of regulation units. The project initially talks about regulation of heating systems for family houses and larger buildings like schools and stores for example. Next, the project describes the control and regulation units and their potential extension for effective and economical operation. Both units are equipped with microcontrollers, which these control each of function. The communication between both units is provided by wireless interface in free radio band ISM. There is a user interface for the master control unit’s regulation process. The measurement and regulation unit has only the possibility to switch between manual and automatic control for regulation of heating system.
