1. Geração distribuída aplicada à edificações : edifícios de energia zero e o caso do laboratório de ensino da FEC-Unicamp / Distributed generation applied to buildings : net zero energy buildings and the case of the laboratory at FEC-Unicamp
Electricity consumption in Brazil increased 47% in the last decade, and it is estimated that it will increase 55.6% until 2020. Most of the electricity generated in the country is based on large hydroelectric dams, located away from the major cities. The planned expansion of the generation park to meet this increase in the demand is also based on this model,

2. Greenhouse tomato production with electricity generation by roof-mounted flexible solar panels
The integration of renewable energy sources into greenhouse crop production in southeastern Spain could provide extra income for growers. Wind energy could be captured by small to medium-sized wind turbines, gas could be produced from biomass, and solar energy could be gathered by solar panels. The aim of this study was to examine the effect of flexible sola

3. ANÁLISE ESTRUTURAL DE PÁS DE GERADOR EÓLICO DE PEQUENO PORTE FEITAS DE FIBRA VEGETAL BRASILEIRA / STRUCTURAL ANALYSIS OF BLADES SMALL WIND GENERATOR MADE OF BRAZILIAN VEGETABLE FIBER
The wind energy potential in the Northeast of Brazil, and especially in the state of Ceará is huge and offers conditions to compensate the missing options for building further full size hydroelectric Power plants and to guarantee the energy supply for this region with green renewable energy. Apart from that it offers opportunities for promoting a sustainabl

5. MODELO PARA A ANÁLISE ECONÔMICA E FINANCEIRA EM PROJETOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA COM FONTES ALTERNATIVAS / MODEL FOR THE ECONOMIC AND FINANCIAL ANALYSIS OF DISTRIBUTED ENERGY GENERATION PROJECTS WITH ALTERNATIVE SOURCES
The implementation of distributed generation (DG) offers many benefits to the society, the electrical sector where they operate, and the consumers connected to the network especially due to their electricity self-production. For this case, proponents normally fight against costs estimation problems in projects of DG. In this way, low-cost and quality pre-fea

6. Three-dimensional flow calculations of axial compressors and turbines using CFD techniques.
With the advent of powerful computer hardware, Computational Fluid Dynamics (CFD) has been vastly used by researches and scientists to investigate flow behavior and its properties. The cost of CFD simulation is very small compared to the experimental arsenal as test facilities and wind-tunnels. In the last years many CFD commercial packages were developed an

7. Metodologia de projeto de turbinas eólicas de pequeno porte. / Methodology for small wind turbines design.
O potencial eólico do Brasil, de vento firme e com viabilidade econômica de aproveitamento, é de 143 GW. Isso equivale ao dobro de toda a capacidade da geração já instalada no país. No Brasil, a energia eólica tem uma sazonalidade complementar à energia hidrelétrica, porque os períodos de melhor condição de vento coincidem com os de menor capaci

9. Potencial de bombeamento eÃlico : uma metodologia de anÃlise
Water and energy represent important needs for humanity and, nowadays, lots of debates focus on how to reduce the effects of unavailability of these resources on several regions around the world. In Brazil, the Northeast region is the main example about the increase of poverty, starvation, and communities depression created by the scarcity of potable water.

10. AnÃlise de projeto de turbina eÃlica de grande porte para as condiÃÃes climÃticas da regiÃo Nordeste do Brasil
The main aim of this work is to quantify the modifications on the energy generation and extreme and fatigue loads of a wind turbine operating particularly in a well concentrated wind speed distribution near to the mean value. This particular meteorological condition is commonly found in the Northeast region of Brazil. The wind speed distribution is modeled i
