Pełny tekst źródłaHoje em dia, as mudanças climáticas e o efeito estufa são questões globais importantes que precisam da cooperação entre os diferentes campos de estudo a serem resolvidos. A solução é bilateral, de um lado há um esforço significativo na União Européia para substituir os recursos convencionais de energia por energia renovável, como Solar, Eólica, Onda e Marés, enquanto outra solução é otimizar os consumos. Edifícios sustentáveis e edifícios com energia zero são as principais soluções em projetos de construção eficientes. Em caso de sustentabilidade na indústria de construção e arquitetura, o Zero Energy Building é uma tecnologia de última geração que aproveita os recursos locais de energia renovável enquanto é construída de forma otimizada com aquecimento, resfriamento e iluminação naturais para consumir água e energia no menor nível possível nível. Por outro lado, o roteiro europeu em diferentes campos do desenvolvimento urbano, cidade inteligente e cidades verdes, precisa de uma atenção considerável em edifícios sustentáveis e de energia zero. Neste projecto, um edifício sustentável foi concebido para funcionar como um centro de lazer público na antiga e turística região de Lisboa. Uma das principais questões da construção sustentável em pontos históricos é a morfologia da região e as situações geográficas que não podem ser alteradas devido ao impacto negativo que ela terá na aparência da região. Assim, nesta tese um lote vago da cidade é usado como o terreno do projeto e o desenho é realizado com base nas características, potenciais e restrições da zona. A funcionalidade do edifício inclui um health club, duas lojas e um restaurante, além de um espaço verde. Além disso, uma escadaria que passa pelo espaço verde aumenta a acessibilidade da região, que é um dos principais problemas nessa área de Lisboa.
ABSTRACT:Nowadays climate change and the greenhouse effect are important global issues which need the cooperation between different fields of study to be solved. The solution is bilateral, on one side there is a significant effort in the European Union to replace conventional energy resources with renewable energy such as Solar, Wind, Wave and Tidal while another solution is to optimize the consumptions. Sustainable buildings and zero-energy buildings are the main solutions in efficient building designs. In case of sustainability in building and architectural industry, Zero Energy Building is a state of the art technology which takes the advantage of local renewable energy resources while it is built optimally with natural heating, cooling, and lighting to consume water and energy in lowest possible level. On the other hand, European road map in different fields of urban development, smart city and green cities, needs a considerable attention in sustainable and zero energy buildings. In this project, a sustainable building is designed to operate as a public leisure center in the old and touristic region of Lisbon. One of the main issues in sustainable construction in historical spots is the morphology of the region and the geographic situations that cannot be changed because of the negative impact that it will have in the appearance of the region. So, In this thesis a vacant lot of the city is used as the project land and the design is fulfilled based on the zone characteristics, potentials and constraints. The functionality of the building includes a health club, two shops, and a restaurant in addition to a green space. Also, a stairway passing through the green space increases the accessibility of the region which is one of the key problems in that area of Lisbon.

Pełny tekst źródłaLa infraestructura de Internet, tanto de red como de centros de proceso de datos, ya alcanza un enorme volumen, pero este incremento no ha sido compensado con la misma rapidez en aspectos relacionados con el gasto energético. El consumo de energía y las emisiones de gases efecto invernadero (GEI) de Internet han pasado a ser un problema relevante en la sociedad de la información y las comunicaciones. En este entorno, falta un paradigma de largo alcance orientado a la energía, que considere el consumo de energía, las emisiones de GEI y la disponibilidad de recursos renovables. Esta Tesis está enfocada hacia estos problemas e intenta compensar la falta de ese paradigma en la infraestructura de Internet, proponiendo modelos energéticos para nuevas arquitecturas, así como algoritmos y protocolos conscientes de la energía para optimizar su uso y minimizar las emisiones de GEI, preservando los objetivos de calidad tradicionales de redes y centros de procesamiento de datos, así como asegurar la posibilidad de servir el mayor número de demandas posible y maximizar la disponibilidad del sistema. Para alcanzar una infraestructura de Internet orientada a la energía, se han solucionado problemas específicos y ligados a una estructura común de largo alcance. Hacia este objetivo, se ha modelado a través de modelos energéticos el consumo de los dispositivos bajo diferentes cargas, y se han valorado diversas estrategias de gestión de la energía para que las infraestructuras de red alcancen funcionalidades avanzadas con un presupuesto de energía limitado. Se han propuesto esquemas integrados de encaminamiento y asignación de longitud de onda (RWA) (formulaciones ILP, heurísticas y meta-heurísticas, teoría de los juegos, mínima afinidad, mínimo corte) para diferentes escenarios (conocimiento completo o parcial del estado de la red, control global o individual de los elementos de red, diferentes requisitos de computación y de espacio). Los algoritmos de RWA conscientes de la energía requieren un protocolo de encaminamiento que distribuya informaciones actualizadas sobre el consumo energético y las emisiones de GEI de los elementos de red. Se han desarrollado extensiones de los mensajes de aviso sobre el estado de la red (LSA) del protocolo OSPF-TE para transportar informaciones sobre la energía, añadiendo nuevos TLVs directamente a las extensiones TE de OSPF. El problema de la optimización de las conexiones se ha formulado como un proceso de refinado iterativo de pasos múltiples estructurado como una meta-heurística GRASP, que permite encaminar las conexiones para mantener el tráfico de la red balanceado y liberar recursos para servir posteriores conexiones. Para respaldar las tareas de investigación, se ha desarrollado SimulNet, un simulador de redes de encaminamiento de longitudes de ondas (WDM), para el diseño, optimización y evaluación de algoritmos de RWA. Se ha desarrollado EnergyFarm, un gestor de energía para los modernos centros de procesamiento de datos que, a través de un algoritmo de armonización entre demanda y servicio ofrecido y funcionalidades de agregación de las tareas, permite apagar los servidores no usados respetando los requisitos de las peticiones y las dependencias físicas y lógicas de los dispositivos. Se han evidenciado por primera vez los riesgos relacionados con los ataques orientados a la energía y se ha valorado su potencial impacto. Finalmente, se ha proporcionada una visión holística de Internet orientada a la energía, en la que arquitecturas eficientes energéticamente están alimentadas por una smart grid con fuentes renovables y controlada por un plano de control inteligente y consciente de la energía, capaz de operar en Internet para minimizar su huella ecológica. Los trabajos de investigación de esta Tesis conducen hacia un paradigma orientado a la energía para una infraestructura sostenible de Internet de alto rendimiento que optimice su huella ecológica sin afectar el rendimiento.

Pełny tekst źródłaI sistemi IoT si sono massivamenti entrati nella vita quotidiana per varie applicazioni. Uno dei principali vincoli che inibiscono l'ulteriore sviluppo di queste applicazioni è l'autonomia limitata delle batterie attuali. Inoltre, la sostenibilità energetica è un requisito cruciale per i sistemi impiegati in applicazioni mission-critical. Un approccio ampiamente utilizzato per aumentare l'autonomia dei sistemi IoT è l'uso di fonti energetiche rinnovabili come solare, eolico, termico e altri per alimentare i dispositivi. Ad esempio, una delle soluzioni più diffuse per i nodi di sensori wireless è l'uso di pannelli solari, che possono fornire un ragionevole input di energia. La loro efficienza è determinata dal materiale del pannello che definisce l'efficienza di conversione. Le fonti energetiche rinnovabili sono troppo irregolari per garantire la completa affidabilità del sistema se non sovradimensionate. In realtà, l'approvvigionamento energetico è spesso limitato, il che causa la necessità di adattamento della strategia operativa del nodo per garantire l'affidabilità funzionale del sistema. Tuttavia, la natura inaffidabile delle energie rinnovabili provoca diverse sfide, che affrontiamo in questo lavoro. In particolare, questa tesi studia l'effetto delle imperfezioni della batteria causate dai processi di diffusione interna della batteria sul funzionamento del dispositivo wireless per la raccolta di energia e strategie efficaci di bilanciamento dell'energia per diversi scenari e tipi di sistema. Proponiamo 1) la strategia di trasmissione, che tiene conto delle proprietà della batteria (perdite, recupero della carica, scarica profonda, ecc.) E riduce le perdite di dati e gli eventi di scarica; 2) algoritmi di campionamento adattivo, che bilanciano gli arrivi irregolari di energia, validati sul data logger industriale alimentato da un pannello solare; e 3) cooperazione energetica in contesti WSN e Smart City. Ci concentriamo anche su sistemi IoT di missione critica, in cui la freschezza dei pacchetti consegnati al nodo di monitoraggio da parte delle fonti di informazione (nodi di comunicazione) è il parametro importante da tracciare. In questo contesto, fissiamo l'obiettivo dell'età della minimizzazione delle informazioni tenendo conto dei vincoli della batteria, dell'asimmetria nell'affidabilità delle fonti di informazione e della stabilità degli arrivi di energia, ovvero della velocità di raccolta dell'energia. Questa serie di strategie copre una vasta gamma di applicazioni, scenari e requisiti. Ad esempio, possono essere applicati a una città intelligente rappresentata come un grande sistema di servizi intelligenti interconnessi o come WSN impiegato per applicazioni mission-critical. Abbiamo dimostrato che la conoscenza della batteria e delle caratteristiche ambientali e le proprietà asimmetriche di un sistema sono utili per la progettazione di strategie di trasmissione / rilevamento.

Pełny tekst źródłaEnergy is central to many aspects of socio-economic emancipation. The services that most people in industrialised countries take from granted – adequate lighting, low-polluting heating and cooking energy, telecommunication and entertainment, motive power – are out of reach to large parts of the world’s population. A lack of access to affordable and reliable energy services represents a key obstacle to human, social, and economic development and the achievement of the Millennium Development Goals. As unacceptable and unsustainable as it is, widespread energy poverty represents a stark reality which must be dealt alongside other pressing global issues. Despite the significant efforts by local institutions and governments, utilities and international organisations, the absolute number of energy poor is expected to rise in coming decades in the absence of additional dedicated action. History has shown, however, that significant progress can be achieved with regard to improving energy access in a short timeframe. Remarkable improvements occurred rapidly in several Asian countries (e.g. Vietnam), South Africa and Brazil in the recent past. However, current initiatives to eradicate energy poverty are insufficient in scale and scope, and attempting to address the issue in the same incremental fashion as in the past is clearly inappropriate. Energy for development strategies must go well beyond merely providing light to poor households. They should aim at transformative changes that bring about sustainable development. The recent succession of crises has set back some development progress. The international community needs to adjust swiftly to the new circumstances and provide advice and assistance that is resilient and long-lasting, and creates an environment that is conducive to enhancing endogenous development. Today, there is no technical barrier to providing the billions of energy poor with modern, safe, reliable and affordable energy services. It is our duty to deal with the aspiration of countries to move towards modern economies, and energy is paramount to such transformation. Fortunately, the issue of energy access is receiving greater and greater attention. As an illustrative example, 2012 has been declared by the General Assembly, the main deliberative, policymaking and representative organ of the United Nations, as the International Year of Sustainable Energy for All. It is crucial to capitalise on this momentum, as energy is central to facing many of today's key development challenges. Addressing the issue of energy poverty in a comprehensive manner would have enormous multiple benefits (e.g. health, education, gender equality). The various chapters of this thesis form a coherent ensemble of individual pieces of analysis around a core topic, namely the nexus between energy and socio-economic development. The different chapters, which are based on stand-alone articles, provide contrasting and complementary perspectives around the issue at hand. It consists of applied research as well as methodological development, and forms altogether an integrated assessment of energy for sustainable development. The thesis is organised in such a way so as to present a consistent and structured narrative. In terms of broad structure, the first chapters gauge the issue of energy poverty, or the lack of access to modern energy services. They offer a sense of the magnitude of the challenge at hand, as well as present an assessment of scenarios towards universal energy access. This is followed by insights on the scale of investment required to address the issue. Finally, concrete interventions to overcome some of the issues are discussed. Energy and the Millennium Development Goals While intuitive, the relationship between energy and development is difficult to quantitatively ascertain and has not been analytically explored in detail in the scientific literature. The correlation between access to energy services and development is, however, often addressed in aggregate in the literature, for example by using composite indexes such as the Human Development Index (HDI), or by focusing strictly on economic impacts. This analysis presents a statistical articulation of the link between energy and various proxies of development, using the Millennium Development Goals as a framework. The outcomes confirm the potentially positive influence of access to energy services on development. The assessment provides a perspective on a number of often employed assumptions about the correlation between energy and development, and challenges claims of its universally positive benefits to specific development priorities. It is found that the benefits to development of access to energy services vary considerably. Measuring Energy Poverty Effective policies to dramatically expand modern energy access need to be grounded in a robust information-base. Metrics that can be used for comparative purposes and to track progress towards targets therefore represent an essential support tool. This analysis reviews the relevant literature, and discusses the adequacy and applicability of existing instruments to measure energy poverty. Drawing on those insights, it proposes a new composite index to measure energy poverty. Both the associated methodology and initial results for several African countries are discussed. Whereas most existing indicators and composite indices focus on assessing the access to energy, or the degree of development related to energy, the new index developed – the Multidimensional Energy Poverty Index (MEPI) – focuses on the deprivation of access to modern energy services. It captures both the incidence and intensity of energy poverty, and provides a new tool to support policy-making. Energy Access Scenarios to 2030 for sub-Saharan Africa In order to reach a goal of universal access to modern energy services by 2030, consideration of various electricity sector pathways is required to help inform policy-makers and investors, and help guide power system design. To that end, and building on existing tools and analysis, several ‘high-level’, transparent, and economy-wide scenarios for the sub-Saharan African power sector to 2030 are presented. These simple scenarios are constructed against the backdrop of historical trends and various interpretations of universal access. They are designed to provide the international community with an indication of the overall scale of the effort required. Most existing projections, using typical long-term forecasting methods for power planning, show roughly a threefold increase in installed generation capacity occurring by 2030, but more than a tenfold increase would likely be required to provide for full access – even at relatively modest levels of electricity consumption. This equates to approximately a 13% average annual growth rate, compared to a historical one (in the last two decades) of 1.7%. Scale of Investment for Universal Energy Access To help provide clarity, support political decision making, and inform the design of financial responses, the overall scale of spending required to meet universal access to modern energy services is considered. The existing literature at the global, regional, national, and project levels and disaggregate cost estimates is reviewed in order to provide increased transparency through comparable metrics. A new methodology is developed to calculate three new cost scenarios that attempt to address several existing analytical gaps. As a conclusion, the total cost of providing (near) universal access is expected to be likely considerably higher than published estimates which often focus primarily on capital costs. While recognizing the coarse nature of the analysis, the annual cost of universal access to electricity and clean cooking is estimated at ranging from USD 14 to 136 billion (USD 12 - 134 billion for electrification and USD 1.4 to 2.2 billion for clean cooking) depending on the various scenarios and assumptions. Current Financial Flows related to Energy Access To help inform the design of appropriate and effective policies to reduce energy poverty, this analysis presents an assessment of the current macro financial flows in the electricity and gas distribution sectors in developing countries. It builds on the methodology used to quantify the flows of investment in the climate change area. The approach relies on national gross fixed capital formation, overseas development assistance, and foreign direct investment. These high-level and aggregated investment figures provide a sense of the scale to policy-makers, but are only a small part of the information required to design financial vehicles. In addition, these figures tend to mask numerous variations between sectors and countries, as well as trends and other temporal fluctuations. Nonetheless, for the poorest countries, one can conclude that the current flows are considerably short (at least five times) of what will be required to provide a basic level of access to clean, modern energy services to the ‘energy poor’. Clean Development Mechanism and Sustainable Development The Clean Development Mechanism (CDM) has a twofold objective, to offset greenhouse gas emissions and to contribute to sustainable development in the host country. The contribution to the latter objective seems marginal in most CDM activities. Also, CDM activities are unevenly spread among developing countries. In response to these concerns, initiatives with the objective of promoting CDM projects with broad local sustainable development dividends have been launched, such as the Gold Standard and the Community Development Carbon Fund. The Gold Standard label rewards best-practice CDM projects while the Community Development Carbon Fund focuses on promoting CDM activities in underprivileged communities. Using a multi-criteria method, the potential contribution to local sustainable development of those CDM projects with particular attributes is compared with ordinary ones. This evaluation suggests that labelled CDM activities tend to slightly outperform comparable projects, although not unequivocally.

Pełny tekst źródłaLa ricerca esplora significati, proprietà e capacità analitiche del concetto di densità e delle sue possibili interpretazioni nell’ambito dell’architettura e della sostenibilità. Il suo obiettivo è la determinazione di relazioni tra costruito, energia e forma dei tessuti urbani della città compatta mediterranea ricorrendo alla densità quale parametro utile a decifrarne le specificità. A dispetto della sempre maggiore insostenibilità della città odierna, di fronte alla crisi energetica ed ambientale in atto, recenti statistiche hanno confermato il crescente potere attrattivo delle aree metropolitane. Nel contesto della città compatta europea, i nuovi modelli insediativi basati su principi di risparmio energetico rappresentano una percentuale insignificante rispetto alla città esistente che, nel funzionare, incide notevolmente sull’inefficienza dell’intero sistema metropolitano. In questo quadro, potrebbe essere risolutivo identificare un approccio che individui strumenti e metodi progettuali alla scala urbana piuttosto che a quella architettonica, utili a definire condizioni più appropriate e realmente incisivi per la città compatta. Se riferito in primo luogo a tale scala il rapporto tra energia e forma assume un ruolo centrale sulla variazione delle prestazioni energetiche; allo stesso tempo il concetto di densità appare un’efficace strumento di analisi delle prestazioni morfologiche del costruito. La ricerca si compone di cinque parti. La prima analizza la condizione odierna delle dinamiche urbane ed energetiche, per comprendere ruolo e contributo dell’edilizia alla luce dell’avanzamento del pensiero scientifico e degli strumenti operativi disponibili. La seconda affronta il significato e l’evoluzione del concetto di densità quale parametro di misura, strumento progettuale e fondamento teorico, facendo riferimento in particolare alle interazioni con la forma urbana e la sostenibilità. Nella terza si utilizzano le capacità analitiche della densità per comprovare le implicazioni ambientali e verificare l’esistenza di leggi di dipendenza tra indicatori di sostenibilità urbana e densità. La quarta pone le basi per la comprensione delle relazioni tra densità ed energia alla scala urbana. La quinta parte, infine, indaga tali relazioni nei tessuti compatti di Roma e Barcellona declinandole in termini di caratteri formali e costruttivi, con l’ausilio di modellazioni e simulazioni strutturate allo scopo di controllare i corrispondenti fattori. S’illustra l’influenza di morfologia urbana e caratteri tipologico-costruttivi su guadagno solare e domanda energetica per riscaldamento e climatizzazione, individuando per mezzo di differenti definizioni d’indicatori di densità, i più adeguati ad esprimere con queste leggi di variazione affidabili. I risultati evidenziano che il contributo dell’edilizia alla complessa questione energetica posta dai sistemi metropolitani deve concentrarsi sulla riduzione della domanda - ancor prima che su consumo e impatto - operando con strumenti e metodi interscalari per la trasformazione della città esistente. La densità ha un ruolo privilegiato nel rapporto forma-sostenibilità per capacità interpretative e significati assunti quale categoria teorica e progettuale. A scala metropolitana, indicatori di sostenibilità urbana e densità non sempre mostrano chiare relazioni con le implicazioni ambientali ed energetiche. Morfologia, tipologia e aspetti costruttivi sono i fattori che più intervengono sulla variazione delle prestazioni energetiche dei tessuti urbani. Analizzarli mediante parametri di densità conduce alla comprensione del diverso comportamento energetico, fornendo un contributo agli strumenti d’indagine a scala urbana e favorendo una connotazione più efficiente del costruito riconducibile alla dimensione della densità sostenibile. Il metodo e gli strumenti individuati si offrono come base di conoscenza per trasformazioni consapevoli della città compatta mediterranea
El presente estudio indaga significados, propiedad y capacidad analíticas del concepto de densidad y de su posible interpretación en el ámbito de la arquitectura y de la sostenibilidad. El principal objetivo es determinar las relaciones entre ambiente construido, energía y forma de los tejidos urbanos recurriendo a la densidad como parámetro útil para descifrar sus especificidades de la ciudad compacta mediterránea. A pesar de una siempre mayor insostenibilidad de la ciudad actual, frente a la crisis energética y ambiental en curso, estadísticas recientes han confirmado el creciente poder atractivo de las metrópolis. En el contexto de la ciudad europea, los modelos de asentamiento actuales, basados en principios de ahorro energético, constituyen un porcentaje insignificante frente a la ciudad existente que, funcionando, grava notablemente en consumo el sistema metropolitano. En esta situación, podría ser resolutivo identificar un acercamiento que identifique herramientas y métodos para el proyecto a escala urbana, que sean útiles para definir condiciones más apropiadas y sean realmente eficaces para la ciudad compacta. Si se refiere en primer lugar a dicha escala, la relación entre energía y forma asume una función central para la variabilidad de la prestación energética; al mismo tiempo el concepto de densidad parece una herramienta eficaz para analizar las prestaciones morfológicas del ambiente construido. La investigación se compone de cinco partes. La primera analiza las dinámicas urbanas y energéticas actuales, para entender capacidad y contribución de la construcción a la luz del avance del pensamiento científico y de las herramientas disponibles. La segunda trata el significado y la evolución del concepto de densidad como parámetro de medida, herramienta del proyecto y origen teórico de la arquitectura, con particular referencia a las interacciones con la forma urbana y la sostenibilidad. En la tercera se utilizan las capacidades analíticas de la densidad para comprobar las repercusiones ambientales y verificar la existencia de leyes de dependencia entre indicadores de sostenibilidad urbana y densidad. La cuarta explica las relaciones entre densidad y energía a la escala urbana. La quinta, finalmente, estudia estas relaciones en los tejidos compactos de Roma y Barcelona, explicándolas en función de forma i construcción, con el auxilio de modelos y simulaciones. Se muestra la influencia de la morfología urbana y las características tipológicas y constructivas sobre la captación solar y la demanda energética por calefacción y climatización, individualizando entre diferentes indicadores de densidad los más apropiados para representar tendencias fiables. Los resultados prueban que la contribución de la construcción a la compleja cuestión energética tiene que basarse en la reducción de la demanda - antes que del consumo y del impacto - utilizando herramientas y métodos multi-escalares para la transformación de la ciudad existente. La densidad tiene una función privilegiada en la relación forma-sostenibilidad que depende de sus capacidades analíticas y significados en calidad de categoría teórica y del proyecto. A escala metropolitana, los indicadores de sostenibilidad urbana y densidad no siempre muestran una relación clara con las repercusiones ambientales y energéticas. Morfología, tipología y aspectos constructivos son los factores que más influyen sobre la variación de la prestación energética de los tejidos urbanos. Analizarlos recurriendo a parámetros de densidad, lleva a entender el diferente comportamiento energético, contribuye a las investigaciones a escala urbana y favorece la eficiencia del ambiente construido, con lo cual se reconduce el análisis al concepto de densidad sostenible. La metodología y las herramientas individualizadas se ofrecen como base de conocimiento para orientar las transformaciones de la ciudad compacta mediterránea.

Pełny tekst źródłaDie Notwendigkeit, die Abhängigkeit der Menschheit von fossilen Brennstoffen zu reduzieren ist die treibende Kraft hinter aktuellen Forschungsanstrengungen in den Materialwissenschaften. Folglich besteht heutzutage ein erhebliches Interesse daran Alternativen zu Materialien, die aus fossilen Resourcen gewonnen werden, zu finden. Kurzfristig ist zweifellos Biomasse die vielversprechendste Alternative, da sie aus heutiger Sicht die einzige nicht-fossile, nachhaltige und nachwachsende Kohlenstoffquelle ist. Konsequenterweise werden die Antrengungen neue Syntheseansätze zur Konvertierung von Biomasse und ihren Derivaten in kohlenstoffbasierten Materialien forwährend erhöht. In diesem Zusammenhang hat sich die Hydrothermalkarbonisierung (HTC) als sehr vielseitiges Werkzeug zur Konvertierung von Biomasse-basierten Ausgangsstoffen in funktionale Kohlenstoffmaterialien herausgestellt. Dennoch gibt es bisher wenige Ansätze um rohe Biomasse, genauer gesagt Lignicellulose, direkt in funktionale Materialien umzusetzen. Könnte der direkte Einsatz von roher Biomasse Verfahren wie der HTC zugänglich gemacht werden, würde dies die Nachhaltigkeit des Verfahrens immens steigern. Daher wurde in dieser Dissertation die Hydrothermalkarbonisierung von kohlenhydratreicher (d. h. Lignicelluse) und proteinreicher (d. h. Microalgae) Biomasse systematisch analysiert. Diese Untersuchung galt dem Ziel einen besseren Einblick in das Potential dieser thermochemischen Verarbeitungsmethode funktionale Kohlenstoffmaterialien aus unverarbeiteter Biomasse hervorzubringen zu gewinnen. Die hergestellten Materialien wurden mittels chemischer Aktivierung nachträglich weiter behandelt. Dieser zusätzliche Verarbeitungsschritt ermöglichte die Herstellung hochporöser aktiverter Kohlenstoffe (AC). Die aus Lignicellulose gewonnenen ACs zeigten exzellente Eigenschaften bei der Aufnahme von CO2 und der Hochdruckspeicherung von CH4 währen die aus Microalgae gewonnen Eigenschaften an den Tag legten (z. B. hohe Oberfläche und N-Dotierung), welche sie zu vielversprechenden Materialien für Superkondensatoren machen. Die in dieser Dissertation präsentierte Arbeit zeigte außergewöhnliche Fortschritte in Richtung der Anwendung von unbehandelter Biomasse als Ausgangsmaterial für die Produktion von funktionalen Kohlenstoffen.

Pełny tekst źródłaKommunala energisystem i nordiska miljöer möter flera utmaningar: det kalla klimatet, storskaliga industrier, en stor andel elvärme och långa distanser driver energiförbrukningen. Medan åtgärder vidtas på efterfrågesidan för att minimera energianvändningen, kan utsläppsminskande åtgärder inom gruvdrift, industrier, uppvärmningen och transportsektorn öka förbrukningen av el och biobränslen. Fortsatt tillväxt av intermittent vind- och solkraft ökar elproduktion, men den planerade avvecklingen av svensk kärnkraft kommer att utmana tillförlitligheten i elsystemet i de nordiska länderna. Flaskhalsar i överförings- och distributionsnäten kan begränsa en potentiell tillväxt av elanvändningen i stadsområden, begränsa ny intermittent utbud, och påverka elutbyte mellan länderna. Miljöhänsyn kan begränsa ökad användning av biomassa. Lokala myndigheter är engagerade i att bidra till nationella klimatmål, samtidigt som de följer sina egna mål för ekonomisk utveckling, ökad självförsörjning av energi och överkomliga energikostnader. Mot bakgrund av dessa omständigheter undersöker denna avhandling befintliga tekniska och ekonomiska potentialer för förnybar energi i Norden med fokus på de nordliga länen i Finland, Norge och Sverige. Forskningen syftar vidare till att utveckla optimala lösningar för hållbara nordiska kommunala energisystem, där samspelet mellan stora energisektorer studeras, med tanke på att minimera årliga energisystemkostnader och samtidigt minska koldioxidutsläppen samt analysera påverkan på elimport till och export från kommunen. Denna forskning formulerar ett integrerad kommunalt energisystem som multimåloptimeringsproblem (multi-objective optimisation problem - MOOP), som löses genom att kombinera simuleringsverktyget EnergyPLAN med en evolutionär algoritm implementerad i Matlab. I ett första steg studeras kopplingen av el- och värmesektorerna, och i ett andra steg effekterna av en integrerad och alltmer förnybar transportsektor på energisystemet. Känslighetsanalys på viktiga ekonomiska parametrar och på olika utsläppsfaktorer utförs. Piteå (Norrbottens län, Sverige) är en typisk nordisk kommun som fungerar som en fallstudie för detta arbete. Forskningens slutsatser innebär att det finns betydande teknisk-ekonomiska potentialer för de undersökta förnybara resurserna. Optimeringsresultaten visar att koldioxidutsläppen från ett nordiskt kommunalt energisystem kan minskas med cirka 60% utan en avsevärd ökning av de totala energisystemkostnaderna och att den högsta elimporten kan minskas med upp till 38%. Resultat för år 2030 visar att transportsektorn kan ha en mycket hög elektrifieringsgrad och samtidigt används biobränslen i tunga fordon. Optimala lösningar är mycket känsliga för elpriser, räntor och utsläppsfaktorer. Detta arbete ger viktiga insikter om strategier för koldioxidminskning för integrerade energisektorer i ett perspektiv på nordiska kommuner. Min framtida forskning kommer att förfina transportmodellen, utveckla och tillämpa ett ramverk för beslutsanalys med flera kriterier (multi-criteria decision analysis - MCDA) som ska stödja lokala myndigheter att fastställa tekniskt och ekonomiskt hållbara lösningar i deras energiplanering.

Pełny tekst źródłaConcrete with smart and functional properties (e.g., self-sensing, self-healing, and energy-harvesting) represents a transformative direction in the field of construction materials. Energy-harvesting concrete has the capability to store or convert the ambient energy (e.g., light, thermal, and mechanical energy) for feasible uses, alleviating global energy and pollution problems as well as reducing carbon footprint. The employment of energy-harvesting concrete can endow infrastructures (e.g., buildings, railways, and highways) with energy self-sufficiency, effectively promoting sustainable infrastructure development. This paper provides a systematic overview on the principles, fabrication, properties, and applications of energy-harvesting concrete (including light-emitting, thermal-storing, thermoelectric, pyroelectric, and piezoelectric concretes). The paper concludes with an outline of some future challenges and opportunities in the application of energy-harvesting concrete in sustainable infrastructures.
