The Positive Energy District (PED) concept has been pointed out as key for cities' energy system transformation toward carbon neutrality. The PED may be defined as an energy-efficient and flexible urban area with net-zero energy import and greenhouse gas emissions, aiming toward annual local surplus of renewable energy. Most of the studies and practical experiences about PEDs are based on newly built districts, where the planning and integration of innovative solutions are less complex and more cost-effective. However, to achieve Europe Union's 2050 carbon-neutral ambition, we argue that the transformation of the settled districts is essential, including historic districts, which present common challenges across European cities, such as degraded dwellings, low-income families, and gentrification processes due to massive tourism flows. This paper aims to discuss how the PED model can be an opportunity for historic districts to reduce their emissions and mitigate energy poverty. The historic district of Alfama, in the city of Lisbon (Portugal), is used as a case study to show the potential of energy renovation measures and solar PV production in households, cornerstones of a PED. The annual energy needs potential reduction due to building retrofit is 84 and 19% for space heating and cooling, respectively, while the integration of building-integrated PV technologies in rooftops and windows potentially generates up to 60 GWh/year. At the district scale, these two components of the PED concept could require an investment of 60M€ to 81M€ depending on the PV technologies in the rooftops, a sensitive aspect in historical districts. Unlike other mechanisms to tackle energy poverty, like the social tariffs, the adoption of structural measures like building energy efficiency retrofit and renewable energy integration will contribute to solve the energy poverty problem, which is significant in Alfama, in both the winter and summer. The highlighted investments require an innovative financial scheme to support not only buildings' owners but also tenants, as these are among the most vulnerable to energy poverty. However, the social benefits of that investment, on the health system, air quality, climate resilience, labor productivity, and social integration, would be invaluable.

Celso Garcia, 787, one of the many derelict buildings in the centre of São Paulo, was converted into housing for 84 low-income families. Members of the ULC popular housing movement occupied the vacant former bank branch and, with technical support from the Integra Interdisciplinary Work Cooperative, converted the building into affordable apartments. The project works toward the reversal of the process of exodus from the city centre, proposing housing alternatives in central areas that have lost part of their population in the last several years yet remain rich in urban infrastructure.

This paper reviews how renewable energy applications in rural areas could reduce poverty, create income generating enterprises, and improve overall well-being of communities. In addition to highlighting a wide range of cases from developing countries, the research also points out to multifarious applications of solar energy technologies for rural development. The conventional myths that the poor cannot afford nor manage smart technologies are not true, as evidenced in the cases presented in this paper. Another objective of this paper is to highlight and emphasise the role of institutions, both formal and informal, with their nested partnerships in supporting, promoting and enhancing the use renewable energy technology-based solutions in rural communities of developing and emerging (BRICs) economies. KEY WORDS: solar energy, climate change, renewable energy, rural development, energy-poverty, sustainability, institutions, livelihoods, capacity building

Real Estates

In order to meet the housing shortage, was created popular housing programs for low-income families. In Brazil, these programs differs from the rest of the world, since here the programs are directed to the acquisition of real estate, unlike the rest of the world where the focus is lower rents for low-income families. In the context, this type of program has also been used as a tool against economic crises. Based on these aspects, this article aims to identify how the FGTS funds are being used regarding the housing finance. To perform this analysis was studied the targeting of FGTS funds for social housing in Brazil, thus demonstrating, a convincing growth in this modality and also an exchange preferably after the year 2009, of used real estates to new ones.

The increasing demand of electrical energy and environmental concerns are invigorating the use of renewable energy resources for power generation. Renewable energy resources can provide an attractive solution for present and future energy requirements. In this scenario, solar photovoltaic systems are becoming prominent and sustainable solutions with numerous advantages. However, the utilization of solar photovoltaic systems in distribution generation makes it mandatory to deploy efficient and organized control measures for integrating solar photovoltaic plants with the grid. In this paper, the control of grid-tied solar photovoltaic systems using a Kalman filter-based generalized neural network is presented with a variable step size perturb and observe-based maximum power point tracking controller to extract the maximum power from a solar photovoltaic plant. The presented system provides power-quality enhancement and supports a three-phase AC grid. The proposed approach extracts the load currents’ primary components for efficient harmonics elimination, synchronizes the system with the grid and provides a fast response during rapidly changing conditions. The results of the proposed control technique are also compared with the artificial neural network-based control technique for validation purposes. The proposed algorithm is found more suitable for using a smaller number of unknown weights and training patterns with reduced computational time.

Abstract Energy transitions and decarbonization require rapid changes to a nation’s generation mix. There are a host of possible decarbonization pathways, yet there is vast uncertainty about how different decarbonization pathways will advance or derail the nation’s energy equality goals. We present a framework for investigating how decarbonization pathways, driven by a least cost paradigm, will lead to air pollution inequality across different vulnerabilities (e.g., low-income, energy poverty). If an equitable energy transition is the goal (i.e., one that reaches total equality), using least cost optimization capacity expansion models without strict renewable energy technology mandates will not accomplish this. Thus, it is imperative that decisions regarding national regarding national decarbonization pathways have strict mandates for equality outcomes or be driven by an equality focused paradigm.
