The recently approved regulation on Energy Communities in Europe is paving the way for new collective forms of energy consumption and production, mainly based on photovoltaics. However, energy modeling approaches that can adequately evaluate the impact of these new regulations on energy community configurations are still lacking, particularly with regards to the grid tariffs imposed on collective systems. Thus, the present work models three different energy community configurations sustained on collective photovoltaics self-consumption for a small city in southern Portugal. This energy community, which integrates the city consumers and a local winery, was modeled using the Python-based Calliope framework. Using real electricity demand data from power transformers and an actual winery, the techno-economic feasibility of each configuration was assessed. Results show that all collective arrangements can promote a higher penetration of photovoltaic capacity (up to 23%) and a modest reduction in the overall cost of electricity (up to 8%). However, there are clear trade-offs between the different pathways: more centralized configurations have 53% lower installation costs but are more sensitive to grid use costs (which can represent up to 74% of the total system costs). Moreover, key actor’s individual self-consumption rate may decrease by 10% in order to benefit the energy community as a whole.

O artigo propõe uma discussão teórica acerca das paisagens coexistenciais interespecíficas na urbe, voltando-se especialmente à morada humana. Esta é percebida como o lugar da convivência entre humanos e não-humanos – também se considera o seu entorno, onde aparecem os quintais/pomares e os espaços verdes habitados pela fauna silvestre urbana. A coexistência interespecífica contribui para a diversidade na conformação das paisagens citadinas, sendo que as ambiências domésticas – a localidade do espaço habitado/lócus da experiência íntima – permitem a humanos e não-humanos o compartilhamento de uma vida juntos a partir de diferentes formas de interações simbólico-práticas. As áreas verdes revelam-se lugares de interações interespecíficas diversas na urbe, figurando enquanto espaços de contato. Para as reflexões que proponho realizar, parto de minha experiência de coabitação com gatos domésticos e de meu ofício de etnógrafo que pesquisa as relações entre humanos e não-humanos em uma área verde na cidade de Belém (PA) na Amazônia.Palavras-chave: Paisagens. Cidade. Habitat. Animais. Áreas verdes. Interespécies.The Coexistent and Interspecific Landscapes or About Humans and Nonhumans Sharing Domestics Places in an Amazonian City  AbstractThe paper proposes a theoretical discussion about the coexistent and interspecific landscapes at the urbis, regarding, specially, the human shelter. This is perceived as a place of coexistence between humans and nonhumans – its surroundings where there are yards/orchards and green spaces inhabited by urban wildlife is also considered. The interspecific coexistence contributes to the diversity in shaping cityscapes and the domestic ambiences - the location of the living space/locus of intimate experience - allow human and nonhuman sharing a life together, founded on different forms of symbolic and practical interactions. The green areas turn up in places of diverse and interspecific interactions at the urbis, constituting spaces of contact. Aiming at these reflections, I consider my own coexistence experience with domestic cats and my work as an ethnographer who studies the relationships between human and nonhumans in a green area in the city of Belém (PA) in Amazon.Key words: Landscapes.

In the midst of the epoch of the Urban Anthropocene, citizen engagement is an important step on the path of creating local and global sustainability. However, the factors that motivate civic urban dwellers to become voluntary stewards of nature environments inside cities need research. This is an empirical study based on deep interviews and a grounded theory approach focused on the “inner world” of people in Warsaw, Poland, that engage in green area stewardship. Our approach reveals a commonly shared vision as the prime motivator powering agency in green area stewardship. This vision was articulated as creating a countryside within the city characterized by a stronger sense of community, a shared sense of place and an enhanced connection with nature. While other studies have found inner values or direct benefits as motivating factors for engaging in urban stewardship, we instead found a green vision for re-designing what the “urban” could be like as the prime motivator for transformation—a vision with potential global sustainability implications.

The aim of the article is to highlight the specificity of visual transformations that occur in the modern urban space under the influence of the development of creative industries. The research methodology involves an interdisciplinary approach and engaging a range of cultural, sociological, and philosophical works. The works of modern foreign researchers Z.Bauman, Ch. Landry, D.Hezmondhalsh are attracted.The sphere of urban planning and the problem of creative industries are being studied. Thanks to creative industries is appears new jobs, the solution of social problems (especially in poor areas), as well as the transformation of urban space. The modern city is a reflection of the transformational processes taking place in the world. There is a change in the form of regulation of the city development policy, from the state to the municipal. There are conditions for activating creative industries that can be defined as an individual creative background, skill or talent that can create added value and jobs through the production and exploitation of intellectual property. The development of creative industries has economic feasibility, but this process is accompanied by a change in the image of the city. Urban space is the text of culture, which often combines non-interconnected components. The visual image of the modern city is repulsive and attractive, it is difficult to bring it to a single concept, but it continues to be the center of human life. Scientific novelty lies in the study of the relationship of the development of creative industries in the urban space and their impact on the visual image of the city. Practical significance is connected with the emphasis on the need to invent an individual development strategy for each city as a “creative city”, where the sphere of cultural production is leading. Promising is the direction of creative industries in a single direction and minimizing the factors influencing the negative perception of the vision of the city.

Buildings are the most important part of development activities, consumed over one-thirds of the global energy. Household used the maximum energy around the world, likewise in Pakistan residential buildings consumed about half of total energy (45.9% per year). The study aims to analyze the impact of building design on climate of Metropolitan City Karachi, Pakistan and to evaluate the change in urbanization patterns and energy consumption in the buildings. To have better understanding of the issues correlations was established amongst population, urbanization patterns, green area, number of buildings (residential and commercial), building design, energy consumption and metrological records (climate change parameters) by collecting the data from the respective departments. With the help of the collected data amount of carbon dioxide was estimated. The results reveled that during last 36 years the urban population of Karachi increased exponentially from 5,208,000 (1981) to 14,737,257 (2017) with increase in urbanized area from 8.35 km2 (1946) to 3,640 km2 (2017) that may led to reduce the green area of the city from 495,000 hectors (1971) to 100,000 hectors (2015). Moreover, the building’s design and numbers are being changed from 21 high-rise buildings (2009) to 344 (2017). It may be concluded that change in temperature pattern and climatic variability of the city may be due to increase in population and change in lifestyle that lead to high energy consumption that is prime source of increased in CO2 emission in the environment of Karachi city, However, Greenhouse Gases (GHG) releases are much lower than the levels reported from metropolitan cities around the world.

Abstract : Based on data from the Central Statistics Agency (BPS) of Bali in 2013, the population density in the Metropolitan area SARBAGITA (Denpasar-Badung-Gianyar-Tabanan) was 1.057 inhabitants/km2 with an area of 1.753,63 km2 and population was 1.853.017 inhabitants. Availability of facilities and adequate transportation infrastructure is needed, but in fact the performance of roads in the city center has declined. It is characterized by an increase in travel delay problem. Traffic delay problems in the City of Denpasar commonly occur on the stretch of Gatot Subroto street. To minimize the existing problems, Denpasar City Government plans to develop an underpass at the intersection of Gatot Subroto street and Ahmad Yani street. The aim of this study was to analyze the direct benefits of underpass for road users, to analyze the costs necessary to realize and operate the underpass, and to analyze the economic feasibility of the underpass development investment. Based on primary data and secondary data were obtained from government agencies, the method of analysis in this study used the technique of Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). Economic analysis conducted in this study used three criteria (NPV, BCR and IRR) with three interest rates (12%, 15% and 18% per year) stating that the construction of an underpass was economically feasible. For example in the second scenario where the interest rate 15% gain on the analysis of value NPV, BCR and IRR respectively is Rp. 233.462.340.102,00; 1,948 and 30,81%. Suggestions can be submitted from this research is the need to contemplate the effect of changes in land use in areas close to the area around the underpass and needed further study that takes into account the needs of additional traffic lanes.

We have determined the potential geothermal prospectivity of clean sandstones in the Tubbergen Formation (Late Carboniferous) of the Twente area (eastern Netherlands). We were motivated by the prevailing paradigm that in the Netherlands geothermal power can only be harvested economically through large, expensive installations producing high volumes from high-quality aquifers located between approximately 1500 and 2500 m. No such aquifers are present in Twente. We found that heat production is economically feasible from the Tubbergen Formation sandstones by producing smaller volumes from smaller, highly efficient installations that can be developed at considerably lower cost. Our reinterpretation of publicly available seismic and well data shows that potentially suitable sandstones occur over the whole area with thicknesses of up to 50 m, porosities reaching 20%, and permeabilities reaching 300 mD. The Tubbergen Formation is approximately 400–700 m thick in the study area and contains approximately 60% sandstone. The top reservoir reaches an approximate 1500 m depth in the southwest, and the base reaches some 4300 m in the northeast of the study area. The temperature is expected to range between 60°C and 140°C depending on the depth. The Carboniferous is densely faulted with a block size of approximately 3 × 4 km, each block being a potential target for geothermal development. To determine the economic feasibility, we performed an economic screening for a hypothetical location north of the city of Enschede and backed this up by reservoir simulations. The geologic risks of the Tubbergen Formation are the lack of permeability, reservoir thickness, and lateral extent of the reservoirs. In our judgment, the chance of economic success for this site is 50% or more. Upside potential is present in numerous fault blocks in the study area and in adjacent areas where suitable sandstones with similar porosity and permeability at greater depth and higher temperatures are expected.
