Due to the huge impact negative on the environmental caused by the civil construction, the university plays a majorital role in the proposal of studies and projects that aim the sustainable building. Nowadays, it has been noted the great demand for projects which contain a systemic focus in the tripod of the sustainable development, that is to say, more and more the consumers are demanding that the final result of a project contemplate the social, economic and environmental areas. According to the National Industry Confederation (CNI) and the Brazilian Chamber of the Industry and the Construction (CBIS), the goal for 2020 is that the constructions have an environmental performance 20% higher in comparison to the actual one, starting with an index defined by many indicators, such as: water consumption, energy, residues generation and social-environmental performance of the bought products. In this case, the theme of the project comes around the adequation of scholar institutions to the sustainable construction through simple changes of tecnologies and habits aiming the growth of the environmental eficiency of the enterprise and, consequently, the improve of sustainable practices inside the institution. Once the change is proposed, it will be furnished datas liable of reproduction for the adequation of others scholar institutions, according to it's necessity or interest. After the realization of the studies, it was possible to notice that the environmental performance of a scholar institution can be improved through the implantation of tecnologies of fast return in the investment, such as: flow reducers, rain water reuse system, green roof, retrofit of lamps and execution of a photovoltaic system. Besides the fast return of investment, the monthly economy of the applied tecnologies combined can reach 75% when compared to the actual spending with water and electric energy

Reflections on the Movement STSE, in basic education, have pointed to the introduction of discussions involving the socio-scientific issues, as a way of organization and development of forming processes in science classes. In this sense, the research that we developed sought to bring to physics classes of basic education, the discussions surrounding the relationship between science, technology, society and environment issues related to production and access to electricity and human development. In order to interpret formative aspects of this approach was achieved through a short course. Thus, we discuss in this paper, the discourse of students and a professor of physics who participated in this short course. Therefore, we seek in discourse analysis, reflection on this practice, which has limitations such as lack of recognition of this type of training status by the students as well as possibilities represented by the establishment of training spaces that contribute to the discussion of socio-scientific issues.

The present work focuses on addressing the financing made by BNDES to sucroalcooleiras plants located in the State of São Paulo in Brazil. The study points out the Bank loans at São Paulo due to accumulation of plants technical objects that BNDES loans provide the State, with the installation of new equipment, machinery and services in canavieiros enterprises for electric power generation. Sucroalcooleiras plants are getting financing from BNDES to expand and diversify power generation in the country, mainly in São Paulo, because residential and industrial consumption of electricity grows annually. The offer of new financing to sucroalcooleiras plants for energy production Sao Paulo electric provides continued technical density in São Paulo and the expansion of regional inequality in the country. Therefore, the present study highlights for the period 2008 to 2013 the BNDES financing for are sucroalcooleiras plants in order to highlight the consolidation of technical objects in the State and show that the funding will help in the expansion of regional disparity

The industry of sugar cane has become an important contributor to the generation of electricity in Brazil. Currently there are 434 sugar and ethanol plants operating in the country, 23% of the total export electricity to the National Integrated System (SIN), the state of São Paulo has 182 plants and 30% of them export energy to the SIN. The objective of this study is to compare parameters of electrical efficiency in the sugar and alcohol industry. For the study, three plants localized in the midwest region of Sao Paulo state with great potential for production and exporting bioenergy were chosen. Five energy analyzers LANDYS + GYR SAGA were used for measure the electrical parameters. The variables studied were energy consumption (C) and power factor (PF). For the statistical analysis it was adopteda randomized block design in a factorial 3 5composed of three companies and five sectors of energy consumption,in which: reception(1), milling (2), boiler (3), supporting activities / juice treatment (4), and distillation (5), totaling 15 treatments. Each group comprised 192 repetitions (48 hours 4 measurements per hour). It was concluded that there is no interest for the plans to fix the FP and reach a value 0.92, which is considered the ideal power factor.This,because the plants generate their own energy and are not penalized. Regarding the energy consumed, all sectors had significant differences. When comparingsector to sector, the plant called USB showed no significant differences in sectors 1 and 3, and the plant USC, in sectors 1 and 4. Considering the production units of this sector and selling power this type of evaluation is essential to perform this analysis, since the analyzed sectors are most important in the production of sugar and ethanol, and analyze and monitor these parameters, use and consumption energy can provide a greater supply of energy to be commercialized.

In the wake of current global image involving environmental impacts, the use of wind power has had a remarkable growth in recent years as a technique for generating electricity. In fact, it is a source featuring strong dissemination of technology which provides decrease in costs and a greater access to low-income electricity. PROINFA (Incentive Program for Alternative Energy Sources) promotes a greater diffusion of new technologies for power generation, in particular wind-produced. Due to such a scenario on the exploitation of such energy source, current analysis discusses strategies for the development of domestic wind technology and the implications for electricity-lacking rural areas. Analysis shows a similar behavior between rural populations lacking electricity and the amount of potential energy available in the region. It is expected that this assay will contribute towards the establishment of public policies for wind-energy parks on rural farms in the North and Northeast regions of Brazil.

A radiação solar constitui-se numa inesgotável fonte energética, havendo um enorme potencial de utilização por meio de sistemas de captação e conversão em outra forma de energia. Para a conversão direta da energia solar em elétrica, são utilizadas células fotovoltaicas constituídas, que associadas constituem um módulo fotovoltaico, sendo que também quando agrupados, formam painéis fotovoltaicos. Estes painéis associados a outros equipamentos que transformam ou armazenam energia elétrica para que ela possa ser utilizada é chamado de sistema fotovoltaico. Neste trabalho, foram determinadas analiticamente formas de obtenção de curvas de corrente e potência fotovoltaicas, e também o ponto de potência máxima. Tais métodos foram aplicados no sistema fotovoltaico localizado na FCA/UNESP, sendo utilizado um sistema constituído por três módulos fotovoltaicos. Para o desenvolvimento das equações que regem a potência dos sistemas fotovoltaicos, procurou-se estudar o circuito elétrico de células fotovoltaicas, sendo necessária também a aplicação de métodos numéricos iterativos para a determinação de alguns parâmetros elétricos. De acordo com os teoremas apresentados, foi possível determinar as expressões analíticas da resistência série e do ponto de potência máxima de uma célula fotovoltaica, possibilitando a geração dos gráficos de tais funções com os dados obtidos experimentalmente. Comparando-se os valores obtidos pelas funções com os valores padrões do sistema fotovoltaico instalado, o valor calculado apresentou um erro de 1,03% em relação ao dado pelo fabricante, representando uma excelente aproximação. Desta forma, pode-se concluir que os métodos e teoremas dos sistemas fotovoltaicos apresentados podem servir de auxílio a futuros dimensionamentos para aplicações destes sistemas.
