Bridging the divide between resource management and everyday life: smart metering, comfort and cleanlinessStrengers, Yolande Amy-Adeline, Yolande.strengers@rmit.edu.au January 2010 (has links)
Smart metering residential demand management programs, such as consumption feedback, variable pricing regimes and the remote control of appliances, are being used to respond to the resource management problems of peak electricity demand, climate change and water shortages. Like other demand management programs, these strategies fail to account for (and respond to) the reasons why people consume resources in their homes, namely to carry out everyday practices such as bathing, laundering, heating and cooling. In particular, comfort and cleanliness practices together constitute most of Australia's potable water consumption in urban centres, and represent most of household energy consumption. In addition, new household cooling practices involving air-conditioning appliances are the major contributor to the nation's rising peak electricity demand, which overloads the electricity system on hot days, costing consumers millions of dollars each year. The oversight of comf ort and cleanliness practices in smart metering demand management programs is concerning because these practices are continuing to shift and change, often in more resource-consuming directions, potentially negating the resource savings achieved through demand management programs. This thesis aims to bridge the problematic divide between the policies and strategies of demand managers, and the day-to-day practices which constitute everyday life. Using the empirical 'hook' of smart metering demand management programs and the everyday practices of comfort and cleanliness, this thesis develops a practice-based conceptual framework to study, understand and analyse these practices and the ways in which smart metering demand management programs reconfigure or further entrench them. A series of qualitative methods were employed in studying 65 households across four research groups, focusing specifically on the household practices of heating, cooling, bathing, laundering, toilet flushing and house cleaning. In addition, 27 interviews were conducted with smart metering industry stakeholders involved or implicated in delivering demand management strategies. Together, these lines of inquiry are used to analyse householders' existing and changing comfort and cleanliness practices, the role of several smart metering demand management strategies in reconfiguring these practices, and potential avenues and opportunities for further practice change in less resource-intensive directions. In particular, this thesis highlights the inherent contradictions and problems in accounting for everyday practices within the dominant demand management paradigm, and offers an alternative paradigm termed the co-management of everyday practices. The thesis concludes by briefly identifying the ways in which smart metering could potentially constrain or catalyse a transition towards this new paradigm.

Estimação espacial da migração de consumidores residenciais para a tarifa branca em sistemas de distribuição de energia elétrica /Cunha, Pedro Paulo. January 2018 (has links)
Orientador: Antonio Padilha Feltrin / Resumo: Neste trabalho o espaço geográfico é incorporado ao estudo da análise das potencialidades de migração de consumidores residenciais para uma nova opção tarifária: a tarifa branca. Os trabalhos avaliados no tema não incorporam a análise espacial de dados geográficos. Em geral apresentam as classes de consumo que mais se beneficiam com a adoção da nova opção tarifária e aspectos relacionados à estrutura tarifária de energia elétrica no Brasil. No entanto, o estudo das características do lugar onde pode ser mais provável a migração massiva de consumidores para a tarifa branca pode trazer informações relevantes para direcionar a atenção das distribuidoras de energia na aquisição de medidores eletrônicos e outros equipamentos para determinadas regiões da área urbana do município. Promove-se dessa forma um melhor dimensionamento do sistema elétrico. Os resultados deste trabalho são mapas de probabilidades úteis para indicar as subáreas onde há maior probabilidade de migração de consumidores residenciais para a tarifa branca. Esses mapas indicam que algumas regiões da cidade como a porção central e leste para os anos de 2018 e 2019 exibem maior probabilidade de unidades consumidoras aptas a migrarem para a tarifa branca. Portanto, há nessas regiões uma tendência de redução da demanda de ponta (ou de pico). Espera-se uma mudança de perfil de carga daqueles alimentadores que atendem regiões onde há maior quantidade de consumidores que irão migrar para a tarifa branca. O espaço é incorp...

The works evaluated in the theme do not incorporate the spatial analysis of geographic data. In general, they present the classes of consumption that most benefit from the adoption of the new tariff option and aspects related to the tariff structure of electric energy in Brazil. However, the study of the characteristics of the place where the massive migration of consumers to the white tariff may be most likely to bring relevant information to direct the attention of energy distributors in the acquisition of electronic meters and other equipment for certain regions of the urban area of the County. In this way, a better design of the electrical system is promoted. The results of this work are useful probability maps to indicate the subareas where there is a greater probability of migration of residential consumers to the white tariff. These maps indicate that some regions of the city such as the central and eastern portions for the years 2018 and 2019 are more likely to be consumer units able to migrate to the white tariff. Therefore, there is a tendency in these regions to reduce the peak (or peak) demand. A load profile change is expected from those feeders serving regions where there are more consumers who will migrate to the white tariff. The space is incorporated in this work through technique...

ANÁLISE DE CENÁRIOS COM REDUÇÃO DA DEMANDA DA ORIZCULTURA NA BACIA DO RIO SANTA MARIA COM APLICAÇÃO DO MODELO CRUZ / SCENÁRIO ANALYSIS WITH DEMAND REDUCTION OF RICE PRODUCTION IN THE SANTA MARIA RIVER BASIN WITH APPLICATION MODEL CRUZCunha, Christhian Santana 29 August 2014 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The demand for water in the various sectors of society is increasing due to factors such as population growth, expansion of agricultural land, depletion of water resources and water quality decreased. Among these uses these demands arise that there are two groups of water, consumptive and non-consumptive. Consumptive uses are characterized by causing a change in the quantity or quality of water, either through funding or evictions. Non-consumptive uses do not cause significant changes in the quantity and quality of water, but depend on these to be realized. The irrigation of rice is a consumptive use that is considered high pollution impact by demanding too much water in their production process. The Rio Grande do Sul is responsible for approximately 65% of rice production in Brazil. The watershed of the river Santa Maria, is characterized by having focused their economic bases for rice cultivation and livestock. In the past there have been conflicts over water use between sectors of users of the basin (water supply and irrigation). Thus, this paper proposes the creation of scenarios with the gradual reduction in a range of 1% to 15% in the demand of water for irrigation of rice in funding of water held in the rivers in BHRSM. With the aim of analyzing the results proposed to the management of water demand can assist and serve as input for the process of water resources management. Initially 5 scenarios, Scenario 0, which characterizes the present moment basin, Scenario 1, 2, 3 and 4 which have as a methodological proposal to reduce the demand for water for irrigation were built. The results obtained in this work allow us to analyze the management of water demand can help to increase water availability. The scenarios simulated for the months from November to February showed the highest percentage of attendance when compared to current demand. However, the month of January still has some hydrological drought in reference sections, being necessary to think about rationing or the use of available water in existing reservoirs in the basin. It is estimated that the results obtained with the simulation in demand management, can support the management of water resources of the basin. / A demanda por água nos diversos setores da sociedade vem aumentando devido a fatores como: crescimento populacional, expansão das áreas agrícolas, esgotamento dos recursos hídricos e diminuição da qualidade água. Entre estes usos que originam estas demandas de águas existem dois grupos, os consuntivos e não consuntivos. Os usos consuntivos caracterizam-se por causarem alguma alteração na quantidade ou qualidade da água, seja por meio de captações ou despejos. Os usos não consuntivos não causam alterações significativas na quantidade e qualidade da água, porém dependem destas para serem realizados. A irrigação de arroz é um uso consuntivo que é considerado de alto impacto poluidor por demandar muita água no seu processo produtivo. O Rio Grande do Sul é responsável por aproximadamente 65% da produção de arroz no Brasil. A Bacia Hidrográfica do rio Santa Maria, caracteriza-se por ter suas bases econômicas voltadas para orizicultura e pecuária de corte. No passado existiram conflitos pelo uso da água entre os setores de usuários da bacia (abastecimento e irrigação). Desta forma, este trabalho propõe a criação de cenários com a redução gradual, em uma escala de 1% a 15% na demanda de água destinada a irrigação do arroz, nas captações de águas realizadas nos rios na BHRSM. Com o objetivo de analisar se os resultados propostos com a gestão da demanda de água podem auxiliar e servir como subsídios para os processos de gestão de recursos hídricos. Foram construídos inicialmente 5 cenários, o Cenário 0, que caracteriza o momento atual da bacia, Cenário 1, 2, 3 e 4 que possuem como proposta metodológica a redução na demanda de água destinada a irrigação. Os resultados obtidos com neste trabalho permitem analisar que a gestão da demanda de água pode auxiliar no aumento da disponibilidade hídrica. Os cenários simulados para os meses de novembro a fevereiro apresentaram percentuais de atendimento da demanda maiores quando comparado ao atual. No entanto, o mês de janeiro ainda apresenta déficit hídrico em algumas seções hidrológicas de referência, sendo necessário pensar em racionamento ou a utilização das águas disponíveis em reservatórios já existentes na bacia. Estima-se que os resultados obtidos com a simulação na gestão da demanda, possam subsidiar o gerenciamento dos recursos hídricos da bacia.

Previous issue date: 2011-03-29 / Financiadora de Estudos e Projetos / Demand management is an emerging topic in supply chain management. It is focused on a fast and adequate integration of supplier needs in order to balance and strategically align demand with operational capability in the supply chain. The lack of demand alignment deals with problems in supply chain, which leads to inefficient customer service, poor stock rotation, and high obsolescence rate aggravated by the wide diversity of products. The objective of this thesis was to develop a framework for demand management in the supply chain of grocery products considering the dyadic relationship between the supplier and the wholesale. The research revealed that the framework can be divided into 1) determining factors for the implementation of demand management between the wholesale and supplier and 2) the implementation process of the demand management between these firms. The determining factors involve strategic intent; internal alignment of the strategic policies; supplier segmentation; customer segmentation; reward, expertise, legitimate power and collaborative supply chain orientation. The implementation of this process can be divided into three phases: 1) joint alignment of strategic policies, 2) formulation of business plan and 3) implementation and monitoring of the business plan. Moreover, this process has four elements that permeate it: top management involvement, inter and intra-firm interactions, challenges and benefits of demand management. The benefits reflect on a reduction of the effect of the demand amplification, profitability by improving efficiency and effectiveness, as well as knowledge sharing and learning. / A gestão da demanda é um tema emergente no campo de conhecimento da gestão da cadeia de suprimentos. O que se busca com a gestão da demanda é a rápida e adequada integração das necessidades originadas do mercado na direção dos fornecedores, de modo a balancear e alinhar estrategicamente a demanda com a capacidade operacional ao longo da cadeia de suprimentos. Esse alinhamento da demanda na cadeia de suprimentos enfrenta dificuldades provocando ineficiência no atendimento a clientes, redução do giro de estoque e alto índice de obsolescência agravada pela grande diversidade de produtos. O objetivo desta tese foi desenvolver um modelo para a gestão da demanda na cadeia de suprimentos de produtos de mercearia básica considerando os elos fornecedor e atacadista distribuidor. Para tal, realizou-se uma pesquisa qualitativa por meio da revisão sistemática da literatura e de estudo de caso na empresa Martins e em nove fornecedores desta empresa. A pesquisa revelou que o modelo de gestão da demanda pode ser dividido em 1) fatores condicionantes para a implantação da gestão da demanda entre os elos atacadista distribuidor e fornecedor e 2) processo de implantação da gestão da demanda entre estes elos. Os fatores condicionantes envolvem intenção estratégica; alinhamento interno das diretrizes estratégicas; segmentação de fornecedores; segmentação de clientes; poder de recompensa, de especialização e legítimo; orientação para a colaboração na cadeia de suprimentos. O processo de implantação pode ser dividido em três fases: 1) alinhamento conjunto das diretrizes estratégicas das empresas; 2) formulação do plano de negócios e 3) execução e acompanhamento do plano de negócios. Além disso, este processo apresenta quatro elementos que o permeiam: envolvimento da alta gerência, interações inter e intraempresas, desafios e benefícios da gestão da demanda. Estes benefícios compreendem a diminuição do efeito da amplificação da demanda, o aumento da rentabilidade por meio da melhoria da eficiência e eficácia, como também o compartilhamento de conhecimento e aprendizado pelas empresas.

"Disponibilidade e gerenciamento sustentável do aqüífero Serra Grande no município de Picos - Piauí" / Availability and sustainable management of the Serra Grande aquifer in the municipality of Picos, PiauíClaudio Luiz Rebello Vidal 16 October 2003 (has links)
Este trabalho objetivou determinar a disponibilidade do aqüífero Serra Grande e estabelecer as diretrizes para o seu gerenciamento sustentável no município de Picos, localizado no sudeste do Estado do Piauí. Principal sistema de água subterrânea da região, este aqüífero é o único com capacidade para atender as demandas futuras da população. Porém, a falta de regras básicas na exploração dos seus recursos poderá comprometer sua sustentabilidade. O desenvolvimento deste estudo teve início com a elaboração do modelo conceitual da área e a análise das condições de uso dos recursos hídricos. Nesta etapa, verificando-se que os conceitos hidrogeológicos vigentes consideravam apenas o limite físico do sistema para definir sua disponibilidade, foi estabelecido um novo princípio para determinação do volume de recursos que pode ser explorado de um aqüífero, denominado de princípio sustentável, tendo como base os fatores econômicos envolvidos na sua exploração. Para determinação da disponibilidade física e econômica do aqüífero Serra Grande, primeiramente, foi estimado o déficit hídrico acumulado desde o início da exploração do sistema, estabelecida sua relação com a posição do nível potenciométrico e calculado o custo atual de produção da água. Em seguida, foram traçados dois cenários futuros para a exploração dos recursos hídricos no município, representando os modelos de gestão da oferta e gestão da demanda, para o período de 15 e 50 anos. Posteriormente, foi construído um modelo matemático para representar o sistema de subsuperfície, no qual foi simulada a evolução futura do nível dágua. Com base nos valores obtidos, foi estimado o volume de água a ser produzido do armazenamento, a quantidade de recursos que deverão ser incorporados ao sistema e o custo futuro de produção. Os resultados mostraram que o aqüífero precisará incorporar um volume significativo de recursos, que talvez não esteja disponível na região estudada, e que a elevação real do custo da água poderá comprometer a capacidade de pagamento da população para dispor destes recursos. Verificada esta situação, foram definidas as medidas que precisam ser implementadas para o gerenciamento sustentável do aqüífero estudado, de modo a garantir o abastecimento futuro do município e da região. Com a elaboração deste trabalho, concluiu-se que o aqüífero Serra Grande não é intensamente explorado em Picos, porém é mal explorado atualmente, o que deverá provocar prejuízos na exploração futura dos seus recursos. / This works goals were to determinate the availability of the Serra Grande aquifer and to establish the governess for its sustainable management in the municipality of Picos, located on the southeast of Piauí State. This aquifer, the regions most important groundwater system, has an unique capacity of fulfilling the populations future demand. However, the absence of basic rules for the exploitation of its resources would compromise its sustainability. The study began with the development of the conceptual model of the area and the analyses of the water resources use. During this step, after verify that the hydrological actual concepts only observe the physical limit of the system to define its availability, it was established a new principle to determinate the volume of resources that can be exploited from an aquifer, named sustainable principle, based on the economical factors involved in its exploitation. In order to determine the physical and economical availability of the Serra Grande aquifer, first, it was estimated the water deficit accumulated since the begging exploitation of the system, established its relationship with the potenciometric level and was calculated the present cost of water production. Later on, two hypothetical scenarios concerning future exploration of water resources were drawn, representing the models of supply and demand management, for a period of 15 and 50 years. Furthermore, a mathematic model was built to represent the subsurface system, which was simulated the evolution of the water level. Based on the values found, it was estimated the amount of water that should be produced from storage, the quantity of resources that have to be incorporated to the system and the future production cost. Moreover, the results showed that the aquifer will need to incorporate a meaningful quantity of resources, that may be not available in the studied region, and that the real increase of the cost of the water would compromise the payment capacity of the population to dispose those resources. After verify this situation, it was defined the actions that must be taken for the sustainable management of the studied aquifer, to guarantee the future water supply of the municipality and the region. In conclusion, this work confirmed that the Serra Grande aquifer is not overexploited in Picos, instead, it is not being correctly exploited, which will negatively affect the future exploitation of its resources.

Cross-sector policy research : insights from the UK energy and transport sectorsPeake, Stephen Robert January 1993 (has links)
Following established traditions in anthropology and sociology, where cross-border research helps to identify important themes which benefit from comparative study, this dissertation introduces cross-sector policy research as a new methodology for generating useful insights about public policy. The cross-sector method is applied to the study of the UK energy and transport sectors. A range of generic policy developments in the energy sector are identified including: the development of efficiency indicators, scenario analysis, and the establishment of energy efficiency programmes. Such developments have not, as yet, occurred in the transport sector. A structural analogy between energy and transport is developed which is used to generate a range of innovations for transport policy including: gross mass movements and intensities as indicators of the efficiency with which the economy uses transport; the projection of a quantitative scenario of sustainable mobility; and the outline of a transport efficiency programme. The insights from the analogy are generalised to consider the benefits of a wider application of cross-sector policy research to other policy areas.

Water and Wastewater Management in the Mega City Istanbul : A General Analysis from a Supply-Demand-Reuse PerspectiveMutailifu, Kalibeinuer January 2019 (has links)
With a population of over 13 million, Istanbul is one of the biggest city in Europe. The possible increase of population in the future may bring serious problems of water supply after a few decades. Therefore, it is crucial to look for good solutions to problems and potential challenges in water supply and water demand. This paper intended to investigate the currently existing problems in water and wastewater management practices in Istanbul from a supply-demand-reuse perspective; and to look for possible opportunities for a future improvement in order to achieve a sustainable urban water management system in Istanbul by promoting its wastewater management system. In this paper, two interviews of professionals, and a survey in Istanbul city area were conducted for obtaining gather primary data. Analysis of relative literatures is applied for grasping an accurate picture of water and wastewater management in Istanbul. According to the study, authorities are making great efforts to meet the ever increasing demand for water. From a supply-demand-reuse management perspective, Istanbul is still at the stage of supply management with sufficient wastewater treatment. However, there is not much sign of a demand management model, as inadequate effort has been devoted to controlling the increase of water demand. Although reuse management may still be a distant goal for Istanbul to achieve, a good preparation can be started by promoting and further improving the current wastewater management system, as wastewater reuse, if properly managed, will be the best solution that will lead to achieving long-term benefits.

Akzeptanz von Straßenbenutzungsgebühren: Entwicklung und Überprüfung eines ModellsSchade, Jens 27 October 2005 (has links)
Several research projects all over the world have considered transport pricing measures and policies as promising attempts to solve urgent traffic problems in urban areas. One important precondition for the successful implementation of pricing strategies is public acceptability. However, empirical findings have shown that the acceptability of such strategies in general is very low. Aim of this dissertation is to analyse the reasons for the low acceptability of road pricing. The dissertation is organized as follows: Firstly, the problems related to transport and the measures to cope with these problems are outlined. The focus is thereby on economic measures such as road user fees, whose economic and traffic-related assumptions are discussed. Then, a definition of the terms used is given and main European results concerning the current acceptability level of various travel demand management (TDM) strategies are reported. Moreover, a theoretical framework is developed which attempts to identify the essential factors determining transport pricing acceptability. In two empirical studies (N1 = 923, N2 = 667), it is investigated whether and to what extent these factors contribute to the explanation of acceptability. Finally, conclusions are drawn and some recommendations for future research are given. / Straßenbenutzungsgebühren für den privaten Autoverkehr sind vielfach als sinnvoll und wünschenswert vor allem zur Lösung der zahlreichen Verkehrsprobleme in städtischen Ballungsräumen begründet worden. Bisher ist es jedoch nicht zu einer nennenswerten Umsetzung dieser Maßnahmen gekommen. Es herrscht in der Literatur Einigkeit, daß die geringe Akzeptanz von Straßenbenutzungsgebühren in der Bevölkerung und die deutliche Ablehnung bei den betroffenen Autofahrern die wesentlichen Gründe für den fehlenden politischen Willen sind, road pricing einzuführen. Ziel dieser Arbeit war es, die Ursachen und Bedingungen für die mangelnde Akzeptanz von Straßenbenutzungsgebühren bei den betroffenen Autofahrern zu untersuchen. Die Arbeit ist wie folgt aufgebaut: Im ersten Abschnitt wird die Ausgangslage und der Problemhintergrund dargestellt. Es wird erläutert, welche negativen Konsequenzen des motorisierten Individualverkehrs vorliegen, und mit welchen Maßnahmen ihnen begegnet werden kann. Der Fokus liegt dabei auf preispolitischen Maßnahmen wie Straßenbenutzungsgebühren, dessen ökonomische und verkehrswissenschaftliche Annahmen dargestellt werden. Dem gegenübergestellt wird die gesellschaftspolitische Realität: zum einen in Form der massiven Ablehnung von Straßenbenutzungsgebühren durch Bevölkerung und betroffene Autofahrer und zum anderen in Form der zahlreichen, erfolglosen und gescheiterten Versuche, Straßenbenutzungsgebühren einzuführen. Dies mündet in die Ableitung erster Forschungsfragen und in die Entwicklung des Untersuchungsansatzes. Im darauf folgenden Abschnitt werden die theoretischen Grundlagen zur Untersuchung der Akzeptanz von Straßenbenutzungsgebühren gelegt. Dabei wird zunächst geklärt, wie sich der Begriff "Akzeptanz" definieren läßt und in welche relevanten psychologischen Theorien er sich einordnet. Im Anschluß wird das Modell zur Akzeptanz von Schlag vorgestellt und analysiert. Darauf aufbauend werden die zentralen Variablen des Modells auf ihre theoretische und empirische Relevanz und unter Berücksichtigung potentiell konkurrierender Ansätze dargestellt und untersucht. Ziel ist die Klärung der logischen und kausalen Struktur des Modells und der Beziehungen der Variablen untereinander. Dies führt schließlich in die Ableitung überprüfbarer Hypothesen in Form eines erweiterten Akzeptanzmodells. Zur Überprüfung des Modells, der aufgestellten Hypothesen und Forschungsfragen werden zwei Untersuchungen berichtet (N1 = 923, N2 = 667), die inhaltlich aufeinander aufbauen. Diese wurden im Rahmen der EU-Forschungsprojekte TransPrice und AFFORD durchgeführt. Generelles Ziel ist die Validierung der Modellkonstrukte und ihrer angenommenen Beziehungen. Im letzten Abschnitt werden zusammenfassend und basierend auf den beiden Studien die wesentlichen Ergebnisse rekapituliert, sowie offene Forschungsfragen und Anforderungen abgeleitet, die sich zukünftigen Studien stellen. Schließlich wird diskutiert, welche Implikationen sich aus dieser Untersuchung ziehen lassen und welche Aspekte zu berücksichtigen sind, wenn Straßenbenutzungsgebühren der Öffentlichkeit präsentiert werden. - Die Druckexemplare enthalten jeweils eine CD-ROM als Anlagenteil: 490 KB - Nutzung: Referat Informationsvermittlung der SLUB
