PREFERÊNCIAS PAISAGÍSTICAS NO ENTORNO DE RIOS URBANOS: UMA REVISÃO

Under the practice of urban environmental planning, design and management, thewater bodies and their riverbanks is a challenge that cities have faced in the last decades due to new ecological paradigms towards a sustainable society. Research regarding landscape preference on urban riverbanks are important to understand the perception of user on of the interface between the natural and built environment, thus contributing to new practices on urban environmental planning, design and management. Therefore, this study aims to identify and systematize the attributes of landscape preference on urban riverbanks. The research method involved a Systematic Literature Review (RSL), in which the search was performed in four databases (Scopus, Science Direct, Springer and Scielo), resulting in a compilation of 339 journal articles, of which only 13 were selected for content analysis. The results showed that the most preferred attributes related to urban riverbanks are: recreation and leisure activities, riparian vegetation, naturalised riverbanks, but, in some contexts, there is the preference for artificialized riverbanks, physical and visual accessibility to water, water quality, between others. Such attributes could be considered guidelines for urban rivers restoration projects to recover the ecological quality related to the rivers and promote the quality of life in the cities.No âmbito da prática de planejamento, projeto e gestão ambiental urbana, os corpos d'água e suas margens são um desafio que as cidades têm enfrentado nas últimas décadas devido aos novos paradigmas ecológicos em direção a uma sociedade sustentável.

Smart energy technologies for the collective : time-shifting, demand reduction and household practices in a Positive Energy Neighbourhood in Norway

Within the context of climate and energy crises, the concept of Positive Energy Districts/Neighbourhoods (PEDs/PENs) has been guiding the development of climate-friendly neighbourhoods in European cities towards net-zero emissions by 2050. Demand-side energy reduction and flexibility are crucial to meeting this target by matching demand with renewable energy production; however, it has not yet been empirically investigated in PEDs/PENs areas. Addressing this gap, we aimed to investigate households’ energy practices in a Positive Energy Neighbourhood in Norway, focusing on the role of smart technologies for demand-side reduction and flexibility. A mixed methods approach was applied, combining in-depth and semi-structured interviews, house tours, actual energy consumption, and simulated solar energy production presented as narratives. The results indicated the need to rethink smart energy technologies to address the collective nature of PEDs/PENs by showing that (i) different ways of interpreting and domesticating smart energy technologies impact demand reduction and flexibility of households with implications at the neighbourhood level, (ii) the individualistic design approach of smart energy technologies does not afford community interaction in terms of knowledge transfer and collective engagement, and (iii) collective representations of energy affordability and convenience attributed to such technologies may act as barriers to households’ engagement with demand-side strategies. These results can be seen as recommendations for PEDs/PENs stakeholders and policies to foster the development of community-based smart energy technologies

The Plegma dataset : domestic appliance-level and aggregate electricity demand with metadata from Greece

The growing availability of smart meter data has facilitated the development of energy-saving services like demand response, personalized energy feedback, and non-intrusive-load-monitoring applications, all of which heavily rely on advanced machine learning algorithms trained on energy consumption datasets. To ensure the accuracy and reliability of these services, real-world smart meter data collection is crucial. The Plegma dataset described in this paper addresses this need bfy providing whole- house aggregate loads and appliance-level consumption measurements at 10-second intervals from 13 different households over a period of one year. It also includes environmental data such as humidity and temperature, building characteristics, demographic information, and user practice routines to enable quantitative as well as qualitative analysis. Plegma is the first high-frequency electricity measurements dataset in Greece, capturing the consumption behavior of people in the Mediterranean area who use devices not commonly included in other datasets, such as AC and electric-water boilers. The dataset comprises 218 million readings from 88 installed meters and sensors. The collected data are available in CSV format

A percepção da paisagem: o caso do Rio Carahá no contexto urbano de Lages, SC

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Arquitetura e Urbanismo, Florianópolis, 2020.Os paradigmas ambientais contemporâneos vêm transformando os modelos de planejamento urbano ambiental, especialmente o tratamento dado aos corpos d?água e suas bordas: promovendo a recuperação dos rios, tornando suas margens espaços multifuncionais e vetores de urbanidade que contribuem para a qualidade de vida nas cidades. Apesar dos avanços recentes, estudos demonstram que esses novos modelos ainda possuem desafios e lacunas a serem estudadas, como a relação entre qualidade ecológica e estética que se apresenta dicotômica no âmbito das pesquisas em percepção ambiental, além da integração entre as funções ambientais e urbanas, importante debate no contexto brasileiro que possui tal problemática associada a sua legislação ambiental. Nesse sentido, a fim de compreender essas questões e contribuir com esses novos modelos, o presente estudo investigou as percepções e preferências visuais atreladas à paisagem do rio Carahá, em Lages/SC, através de uma abordagem multimétodo sob o aporte teórico da percepção ambiental. Os objetivos específicos da pesquisa envolveram; (I) Identificar a imagem ambiental (individual e coletiva) associada ao rio; (II) Examinar as relações afetivas dos habitantes para com o rio e a influência do afeto na construção das imagens cognitivas; (III) Expressar a preferência visual dos habitantes em relação às possíveis configurações das margens do rio. Para tanto, realizou-se pesquisa documental, entrevista semiestruturada com os moradores do entorno do Carahá (n=53) e um fotoquestionário online com os moradores da cidade de Lages (n=320). Os dados qualitativos foram submetidos à análise de conteúdo, enquanto os dados quantitativos foram analisados através de estatística descritiva e do teste Chi-quadrado de Pearson. Os principais resultados referem-se à classificação e categorização das múltiplas imagens ambientais associadas ao rio, bem como sua imagem coletiva (lixo/sujeira) e idealizações para seu futuro (despoluição). Com isso, examinou-se que o afeto está intrinsecamente relacionado à construção das imagens cognitivas, pois os relatos apontaram para o sentimento de aversão ao rio devido à poluição e inundações. Por fim, na etapa do fotoquestionário através da seleção dos cenários de maior e menor preferência, observou-se que os respondentes desejam a integração entre ambiente natural e construído, rejeitando a hipótese de uma paisagem totalmente artificializada. Nessa mesma linha, o teste Chi-quadrado de Pearson indicou que existe dependência (p-valor < 0,05) entre nível de naturalidade das margens e lazer-recreação passiva, corroborando o debate teórico sobre o caráter multifuncional das margens dos rios urbanos. Diante do exposto, considerando que os estudos de percepção ambiental transformam dados subjetivos em instrumentos objetivos à arquitetura e urbanismo, os resultados obtidos contribuem para o planejamento e desenho das margens dos rios urbanos através da premissa de integração entre as funções ambientais e urbanas, qualidade ecológica e estética. Já na escala do estudo de caso, as temáticas extraídas das entrevistas são potencialmente uma lista de prioridades aos gestores públicos municipais em prol da recuperação do rio Carahá, ressignificando sua imagem negativa perante à população e motivando a afeição pelo lugar.Abstract: Contemporary environmental paradigms have been transforming models of urban environmental planning, especially the treatment given to water bodies and their edges: promoting the restoration of rivers, making their riverbanks multifunctional spaces and vectors of urbanity and contributing to the quality of life in the cities. Despite recent advances, studies have shown that these new models still have challenges and gaps to be studied, such as the relationship between ecological and aesthetic quality that is dichotomous in the environmental perception research field. Furthermore, in an important discussion in Brazil, the environmental legislation has problems with the integration between urban and environmental functions. In this context, the present study seeks to understand and contribute to these new models by investigating the visual perceptions and preferences associated with the landscape of the Carahá River, in Lages/SC, through a multimethod approach under the theoretical support of environmental perception. The specific objectives of the research involved: (I) Identify the environmental image (individual and collective) associated with the river (II) Examine the affective relationships of the inhabitants towards the river and the influence of affection in the construction of cognitive images (III) Express the visual preference of the inhabitants about the possible configurations of the riverbanks. Thus, a documentary research was carried out and a semi-structured interview with the residents of the Carahá surroundings (n = 53) and an online photo questionnaire with the Lages citizens (n=320). Qualitative data were submitted to content analysis, while quantitative data were analysed using descriptive statistics and Pearson's Chisquare test. The main results were the classification and categorisation of the multiple environmental images associated with the river, as well as its collective image (garbage/dirt) and idealisations for its future (depollution). It was observed that affection is intrinsically related to the construction of cognitive images, as the reports pointed to the feeling of aversion to the river due to pollution and floods. Finally, in the photo questionnaire stage through the selection of the most and least preferred scenarios, it was observed that the respondents would like the integration between the natural and the built environment, rejecting the hypothesis of an artificial landscape. In the same way, Pearson's Chi-square test indicates that there is dependence (p-value < 0.05) between the naturalness of the riverbanks and passive leisurerecreation, corroborating the theoretical discussion about the multifunctional character of the urban riverbanks. Thereby, considering that environmental perception studies turn subjective data into objective instruments for architecture and urbanism, the results obtained contribute to the planning and design of the urban riverbanks through the premise of integration between environmental and urban function, ecological and aesthetic quality. In addition, about the case study, the themes extracted from interviews are potentially a list of priorities for public managers in favour of the restoration of the Carahá River, reframing their negative image and motivating the affection for the plac

A complex mixed-methods data-driven energy-centric evaluation of net-positive households

Following the Paris agreement, different policy incentives aiming at the reduction of carbon emissions have been introduced worldwide. Dwellings that benefit from increased renewables penetration, aiming at achieving net-zero and even net-positive energy balance, are being designed and deployed in different countries. This article presents a design mixed-methods approach, based on collected quantitative and qualitative data, to answer the "what", "why" and "how" of energy prosumption in netpositive dwellings. We demonstrate the strong influence of domestic routines and dynamic energy import and export pricing on explaining energy-centric deviation from net-positive design ambitions. Findings from net-positive neighbourhood households, equipped with geothermal heating, solar generation and electric vehicles, in Norway further provide actionable insights on demand-side reduction and flexibility in energy consumption and how to achieve true energy net-positive balance. Specifically, our analysis demonstrates a significant gap between actual energy bills and user expectations, and potential energy cost reduction up to 10% on a per-activity basis through demand side flexibility in relation to dynamic tariffs as well as a maximum observed bill reduction of up to 50% compared to the baseline scenario for households not adapting their activities inline with dynamic tariffs
