PhD Thesis (2013): Evaluation of Energy Supply Infrastructure in the context of Life-cyce analysis of alternative light-duty vehicles
Thesis abstract: Many transportation environmental life cycle analyses (LCA), neglect the contribution of the energy supply infrastructures. In alternative light-duty vehicle technologies, it has been shown through case studies that this can be a relevant factor. However, no model exists to generalize the evaluation of emissions and energy from construction, maintenance and decommissioning of such infrastructure in different scenarios. This study proposes a model, focusing on electricity and on hydrogen supply through centralized steam methane reforming, H2(a), and on-site electrolysis H2(b). The model outputs are in gCO2eq and MJeq per MJ of final energy. The model main inputs are: the region’s electricity mix, the annual distance driven, the supply chain losses and the number of vehicles per station or electric chargers. The evaluation of the number of vehicles served per each charger/station as a function of annual distance driven is also discussed. The uncertainty in the study is incorporated by using the pedigree matrix, the impact uncertainty and literature estimates. The study shows that infrastructure impacts are higher in alternative vehicle pathways. Moreover, higher renewable energy penetration in the electricity mix means higher contribution to infrastructure LCA. The model shows consistency in the results and in the uncertainty range. Charging policies that minimize the electricity infrastructure burden should incentivize approximately 37% of vehicle charging in normal chargers. H2(a) pipeline lifetime should be extended and improvements in the electrolyser should be undertaken, to approximate the ratio of vehicles per station to a conventional one.

Research topic/area: Integrated Energy Management Algorithms with Responsive Demand and local generation/storage
Research Summary: The goal of the research is to design a methodology to be implemented in an integrated energy management system for controlling domestic energy resources in a smart grid scenario, taking into account different inputs signals as well as considering uncertainty and multiple criteria evaluation aspects in order to obtain robust decisions. Domestic energy resources comprise typical manageable loads, energy storage systems, plug-in electric vehicles and micro-generation systems. As a consequence of this management, impacts of automated demand response actions in the domestic aggregated load diagram must be adequately assessed, which in turn contribute for subsequent decisions to be made.

Supervisors: Paulo Ferrão (IST), Carlos Silva (IST), Stephen Connors (MIT)
Thesis Abstract:
The shift towards high penetrations of renewable energy sources and the increase in energy efficiency, on both the supply and demand sides, are currently the main challenges that energy systems are facing. To design economically and technically feasible transition pathways to more sustainable energy systems, detailed energy models are required. However, the most commonly used modeling methodologies are not prepared to perform long-term analysis of energy systems while taking into account the inherent hourly dynamics of supply and demand. The work presented in this thesis analyzes the importance of accounting for the dynamics of renewable energy sources availability and of the introduction of changes in the patterns of electricity consumption, through the implementation of demand side management policies or the deployment of electric vehicles, in the optimization of investments in new generation capacity. A new framework that allows modeling the long-term evolution of energy systems while having a high temporal resolution is proposed and tested to develop investment plans for systems with high penetrations of renewable energy sources. The results show that accounting for the dynamics is crucial for avoiding the overinvestment in new generation capacity and increase the cost-effectiveness of the systems.

PhD Thesis (2014): Multi-terminal HVDC grids: control strategies for ancillary services provision in interconnected transmission systems with offshore wind farms
Thesis abstract: Wind Energy (WE) has largely contributed to the de-carbonization of the energy sector and consequently to the definition of the European Commission (EC) targets on renewable-based electricity generation. During the last decade, massive investment has culminated in the substantial installation of Wind Farms (WF). Moreover, the ambitious plans for increasing these targets on renewable-based electricity generation demand the deployment of more WF. To tackle this challenge, a large amount of offshore WF is envisioned to be built during the next decade. From the technical perspective, the adoption of HVDC becomes crucial to allow the installation far from coast and large power WF. Most recent plans point for the adoption of DC-grids as the mean of interconnecting offshore WF and also inter-AC area, allowing further renewable integration and the development of a common European electricity market.This thesis presents control strategies based on a communication-free framework that were developed in order to allow DC grid-connected offshore WF and interconnected AC areas on providing advanced system services such as: a) primary frequency regulation, b) inertial behavior emulation, c) Fault Ride-through (FRT) capability. The association of the control strategies for primary frequency regulation and FRT has culminated in the design of the coordinated approach for increasing the DC grid reliability by allowing its operation following the disconnection of one onshore HVDC converter. The presented control strategies rely on local controllers to be housed in offshore and onshore High Voltage Direct Current – Voltage Source Converter (HVDC-VSC) as well as on WT. The local controllers operate autonomously providing the adequate regulation based on quantity variations. The main outcomes of this thesis consist on the development of communication-free control strategies for MTDC grid with offshore WF participating in the mainland systems frequency regulation, the capability of remaining connected to the mainland grids during voltage sags, thus mitigating the problems resulting from the disconnection of a large amount of wind power. Finally, a control scheme to guarantee the operation of the DC grid following the disconnection of one evacuation node (onshore HVDC-VSC) is presented.

Thesis Title: Towards Electrical Isolated Systems based on 100% Renewables
Supervisors: Eduardo de Oliveira Fernandes (Faculty of Engineering, University of Porto); Carlos Moreira (Faculty of Engineering, University of Porto); Stephen Connors (Massachusetts Institute of Technology)
Research summary: Energy supply faces enormous challenges given the costs of fuels and the still inaccessibility of some new technologies. Islands and isolated energy systems even experience greater energy challenges; high import costs, higher sensitivity to greenhouse gas emissions and climate effects and higher costs for whatever technology. Renewable energy technologies can be a solution to overcome these challenges. A methodological concept for gradually covering all energy purposes that can be electricity based on 100% renewables will be established in this study. Consequently, energy demand and future development, reduction potential as well as local resource potential of renewables need to be assessed. In combination with storage technologies a 100% renewable electricity system will be built. The decision for a specific future supply scenario will be strengthened by a sustainability assessment, which will be compromised of technical, economic, environmental and social criteria. As there are many criteria to be considered, decision makers will have the flexibility to choose supply alternatives based on their preferences and priorities, including onshore and offshore technologies

Research Summary:
Daniel Wiesmann and David Quinn (MIT PhD) have developed an interactive web-map that allows for an integrated understanding of resource use in cities- Urban Energy Patterns. By displaying measures of construction material (kg/person), building and transportation energy use (kWh/person) and population density (people/km2), the researchers hope to contribute to a better understanding of the relationship between these measures and urban development patterns. Thanks to a Google Map satellite imagery, users can examine specific urban areas, and automatically generate a detailed PDF report of the area which they examined.
This work was motivated by a desire to better understand how spatial patterns can be related to material and energy use in cities and therefore the two PhD students have mapped 40 cities across the United States hoping to contribute to the public discussion of urban sustainability. The data shown in the web-map uses a combination of publicly available datasets, survey data, and sophisticated spatial analysis methods at a high-resolution, enabling the prediction of values in cities where some data was not available.

Research summary: The growing motivation of countries to use renewable energy for the production of electricity, nowadays solar thermal plants have increased in number. all solar thermal power plant has mirrors that concentrate sunlight on a point called white, so the presence of concentrated sunlight in large quantities is usual in this type of plants, so you may encounter various risks, including skin type, burns on the skin or ocular type, either from burns in the retina or momentary dazzle (post image effect), which can cause distractions. Some previous studies have provided the possible effects to such exposure. The need for risk assessment on this type of facilities is evident. With the help of Risk Management we pretend to achieve the overall purpose of this research, which is to propose technic security elements in thermal solar power facilities in the way of the development of standard proposal.

Thesis Summary: Retrofitting of existing buildings offers significant opportunities for reducing global energy consumption and greenhouse gas emissions. This is being considered as one of the main approaches to achieve sustainability in the built environment at relatively low cost and high uptake rates. Although there are a wide range of retrofit technologies readily available, methods to identify the most suitable set of retrofit actions for particular projects are still a major technical challenge. Such methods can be categorized into two main approaches; models in which alternative retrofit actions are explicitly know a priori and models in which alternative retrofit actions are implicitly defined in the setting of an optimization model.
This thesis focuses on using modeling and optimization techniques to assess technology choices in the built environment. Firstly two multi-objective optimization models using a classical optimization technique, namely Tchebycheff technique are developed. The functionality of the proposed models is discussed through the application on a residential building. The results verify the practicability of the approaches and highlight potential problems that may arise. Afterward a multi-objective optimization model based on the Genetic Algorithm Integrating Neural Network (GAINN) approach is developed. The benefits of this approach with respect to the classical optimization models are its rapidity and computational efficiency. This model is used for the optimization of the energy consumption, retrofit cost and thermal comfort in a school building. The results from the optimization show the impact of each objective function on the building’s overall performance after retrofit and more importantly illustrate the trade-off between different objectives. Finally, the proposed methodology highlights the improvements added to the GAINN methodology by use of a multi-objective genetic algorithm.

PhD Thesis: Automated Floor Plan Design: Generation, Simulation, and Optimization
Thesis Abstract: “Architects need to design more energy efficient buildings. The best way to achieve this is to incorporate building performance simulation in the design process to estimate how they will behave. However, practitioners rarely make use of such tools. According to recent inquiries on the needs to improve these kind of programs, it can be concluded that they are non user-friendly, demand detailed building specifications that are usually absent from initial architectural design phases, take too much time to build the simulation model, results are not presented in a meaningful way to the architects, and in a trial-and-error design process it becomes unbearable to use. Researchers have been working in the usability of the graphical interface and in the development of optimization techniques to improve the designed building solution. However, such approaches aim to final design stages, when all the most important decisions have been already made and thus too late to implement meaningful design changes. The approach proposed in this research work is fundamentally different, as it aims to assist practitioner in the earliest design phase of architectural practice, the space planning phase. In this phase, architects seek to accommodate all preferences and requirements from the clients design program into floor plan designs. The approach aims to automatically generate, assess, and optimize alternative floor plan designs. Two algorithms were developed. The first generates floor plans by allocating spaces on one or more levels, served by parametric vertical circulation spaces that adapt their shape, dimensions, and position to the evolving design solution. A hybrid evolutionary computation technique is used, which couples the searching capabilities from an Evolutionary Strategy and local search technique. Clustering mechanism is used to incorporate morphological preferences of the user and to give structure to large design programs. Transformation operators perform random geometric and topological mutations aiming to satisfy all requirements and preferences. Self-adaptive mechanism and adaptive operators are used to reduce the computational time, and deepens the exploitation and widens the exploration of the search. The second algorithm imports those generated floor plans and assesses, ranks, and optimizes their thermal performance. It uses a sequential variable optimization procedure, where different architectural elements are added or changed with the purpose of maximizing the thermal performance. The two algorithms were tested in several case studies with different complexity levels, design programs, requirements, and constraints. Both algorithms have their performance analyzed. Results shown that both algorithm may be valuable instruments in speeding up the design process, in enlarging the number of design solutions to be compared, in improving thermal performance of floor plans, and in helping the architects in their decision-making process.”

PhD Thesis (2013): Development of photovoltaic systems with concentration
Thesis abstract: The concept of Concentration Photovoltaic (CPV) systems appeared as an attempt to reduce the cost of Photovoltaic (PV) technology. In these systems, savings are achieved by the reduction of the area of the expensive PV cell which is compensated by the increase in the light intensity on the device through less expensive optical elements. This thesis focus on two main CPV systems: i) the DoubleSun® technology, a low CPV system, already commercialized; and ii) a new medium CPV system, the HSun technology. Regarding the DoubleSun®, the on-field performance and ageing tests are addressed, highlighting the main challenges that a CPV system has to face under outdoor exposure. Such results were relevant for the development of a new CPV system concept, the HSun, whose main target is to achieve grid parity. A Levelized Cost of Electricity (LCoE) analysis was performed showing that this objective can only be achieved with a concentration factor between 15-20 suns and integrating high efficiency silicon solar cells.Within the HSun project, this thesis focuses on the CPV receiver whose design, development, assembly, validation and optimization are discussed in detail. The analysis of its thermal behaviour is addressed through CFD-FEA in a model implemented in SolidWorks which determines the temperature profile across the solar cells showing that its integration on the HSun could be optimized to decrease the average temperature of the cell by about 60°C. Since both illumination and temperature profiles are spatially inhomogeneous, a distributed solar cell electric model is developed in order to understand and fully describe the behaviour of solar cells under such operating conditions. The model was experimentally validated and then applied to the optimization of the front grid of the solar cells on the HSun showing the efficiency may be increased by 1.5% if front grid design integrates more 21 fingers.

Thesis Title (2016): Promoting a cleaner and more efficient energy use in the residential sector through a better understanding of energy consumption patterns
Supervisor: Carlos Silva (IST), Susana Vieira (IST)
Thesis Abstract: This thesis contributes to increasing the knowledge in the Portuguese residential energy consumption. The insight into consumption is provided by measurements from a smart meter project, the Portuguese survey to residential energy consumption and the Portuguese database of energy performance certificates in residential buildings.
The analysis of consumption patterns showed the importance of thermal comfort-related consumption and the influence of external factors like temperature and day length. Furthermore, it was observed a performance gap, i.e., the households active energy consumption was not sufficient to meet the estimated thermal needs. The results suggest thermal comfort as a target for efficiency measures but, in a scenario of possible domestic energy poverty, it is difficult to propose actions when the majority of Portuguese households might not be able to meet thermal comfort needs.
The estimation and classification of residential energy consumption patterns are possible due to the deployment of smart meters. The pattern analysis contributed to the reduction of energy consumption through feedback of performance indicators to households. A shift to cleaner energy consumption could be achieved with distributed production, using on-site renewable energy production and storage. The achieved results suggest that current solar storage technologies and Portuguese legislation would be financially profitable making it an attractive option for households.
Energy efficiency measures (e.g. consumption feedback) and a shift to renewable energy use can increase sustainability in the residential sector.

PhD Thesis (2013) : Feasibility Assessment of Carbon Capture and Storage Technology in the Portuguese Energy System
Thesis Abstract: Carbon Capture and Storage (CCS) is one alternative in the portfolio of options for reducing greenhouse gas emissions that allows significantly to reduce anthropogenic emissions of CO2 from industrial fossil fuel-based combustion plants. Fossil fuels have a dominant share in the Portuguese energy sector and, at the same time, there is a specific focus on the energy sector to maintain national levels of greenhouse gas emissions. Therefore, CCS has been lately receiving increasing interest. The work presented in this thesis improves the understanding of the techno-economics of CCS in the electricity sector and its contribution to the CO2 mitigation within a portfolio of other mitigation options applied to the Portuguese reality. In addition to this, the assessed case studies demonstrate the technical and economic feasibility of using an amine-based post-combustion CO2 capture at particular Portuguese power plants and cement manufacturing plant. The established framework quantifies the contributions of CCS within the Portuguese energy system and as a result provides the most up-to-date and realistic estimates of the environmental and economic impacts that would result if CCS is implemented on large point sources of CO2 in Portugal. Keywords: CO2 emissions; carbon capture and storage; energy systems modeling; fossil fuel power plant; cement plant; CCS retrofitting; cost estimates; electricity generation; CO2 taxes; MEA post-combustion captu

Research Summary: Urban population has been growing consistently worldwide, with large metropolitan areas experiencing persistent expansion phenomena. Unsurprisingly these processes are not occurring homogeneously throughout the territories. Over the last decade, population in suburbs has largely increased while the population living in Central Business Districts has shrunk in many large European and American cities. Portugal is not an exception. The main aim of this work is to establish a modelling framework suitable for the regional and national assessment of economic, social and environmental impacts of changes in urban forms and commuting patterns. Accordingly, this research proposes the construction of a commuting satellite account embedded in a Multi-Regional Input-Output framework.

Research summary: The recent development of new drilling technics, namely the combination of hydraulic fracturing (fracking) with horizontal drilling technologies, in order to get much more oil and gas from a single hole, has opened up the perspective of accessing vast reserves of fossil energy trapped in shale rock formations. Recovery of unconventional oil and gas, however, involves injecting huge amounts of water at high pressures, mixed with sand and chemicals, to break up deep rock formations, and considerable concern has been arising on how this extraction technics might affect surface and groundwater water resources. Furthermore, there’s a growing consensus among major private companies and institutions that water is a strategic issue, as its scarcity, or difficulty to guarantee access at an acceptable cost, will affect industries and increase their business risk over the next 10 to 20 years. In this context, my research aims to determine how water scarcity/cost variability may determine, in a life-cycle perspective, the way different energy sources (with a particular emphasis on unconventional oil and gas) compete between each other

PhD Thesis: Time-Domain Impedance-based fault location for HVDC Transmission lines
Thesis Abstract:
“In the last decades, High Voltage Direct Current (HVDC) systems have had extensive growth due to the great development that has occurred in AC-DC-AC conversion technology based on power electronics, and also for being strongly promoted as a great solution for the connection of renewable energy sources through long distances, both offshore and onshore. However, there are still problems in the operation and maintenance of HVDC systems that can be reviewed and updated. Such is the case of automated methods of fault location. All currently available commercial methods are based on traveling wave technologies. These methods can have good accuracy, but they also have some disadvantages, such as the need for expensive measuring equipment dedicated exclusively to this purpose, and problems for detecting high impedance faults or faults close to the line terminals. This thesis develops a method for fault location on HVDC lines based on line impedance estimation, as a proposal to complement the current methods in cases where commercial methods are not capable to give a satisfactory result. The reason to develop this method based on a different technology than traveling wave, is because it’s intended to prevent the problems that affect these type of technologies. The proposed method uses a mathematical model of the transmission line as a basis for estimating the line’s impedance. This model was specifically attained to use in this project, and it was deducted from the transmission line differential equations in the time-domain. For this deduction is not required any approximation, so it was obtained a model that brings high accuracy to the fault location method. The method’s behavior is evaluated from the technical point of view, using both actual fault records and simulated fault records. The results are compared with results obtained by traditional methods in order to verify the performance of the different methods. The proposed method aims to assist in the operation process of HVDC systems, providing a robust fault locator, with high accuracy, and low cost. This method is intended to replace the current traveling wave-based methods, or at least complement them in cases where traditional methods have not performed well.”

Research summary: The overall purpose of my research is to develop an energy efficiency (EE) plan for renewed schools. The Plan is to be adopted after the analysis of monitored indoor environment quality (IEQ) parameters from renewed schools (geographical and climatically distributed) and the adaptation of operation and maintenance (O&M) measures.Starting with an energy consumption assessment in the school buildings between the pre and post–intervention phases, this study, focusing on the relationships between energy performance and occupant feedback, also intends to explore whether energy use and associated CO2 emissions are correlated to occupant satisfaction and comfort. It aims to enlarge the actual EE plans based only on cost/energy control attending also to an equilibrium between IEQ evaluation and students performance/productivity.

Research Summary: Cities have a specific role on the energy management regarding its impact on the global environment. Buildings are seen as part of the energy problem but can also be part of the solution by responding to the sustainability challenge through Architecture and Construction. The expected outcome of this thesis is a methodology based on an order of merit encompassing the parameters that influence the thermal behavior assuming both comfortable and healthy residential buildings for Portugal. A friendly roadmap for architects not versed in Physics will allow for a major step towards low-energy buildings just at the earlier architectural design stages.

Research Summary: This thesis studies global material extraction, trade and consumption patterns at country level using regression and visualization techniques. The conducted analyses are rooted in material flow analysis (MFA) and utilize non-proprietary global data on: domestic extraction (DE) and international trade, both 1980-2010, and material footprint (MF), 1990-2008. Log-linear regression methods are used to determine the key drivers of domestic material consumption (DMC). Evolution of equitability and patterns of domestic extraction (DE) is studied using Lorenz curves. The impact of GDP/cap on DMC/cap (total) and MF/cap constituents is studied with respect to time and GDP/cap range using elasticies. Finally, the presented research is placed in a larger context of proposed data- and visualization-enabled opportunities. An applied example with rice flows is published at: ricestudyvis.weebly.com

PhD Thesis (2013): Multi-criteria decision analysis for the development of sustainable data centers
Thesis Abstract: Data Centers (DCs) are complex organizational and technical infrastructures that contribute to the performance and reliability of modern information and communication systems. The high installation and operations costs of DCs and the stringent requirements regarding reliability and safety require a close attention to the location of this type of facility. Only if all these aspects are taken into account, it is possible to guarantee the design, construction and operation of a DC that is environmentally as friendly as possible, with the lowest cost possible and the highest social and economic benefits, i.e. a Sustainable DC. This thesis proposes a methodology to analyze and support the decision process for identifying regions for the development of a Sustainable DC, by using Geographic Information Systems and Multi-Criteria Decision Analysis (MCDA), taking into account technical, social, economic and environmental dimensions. The evaluation was formulated as a fourfold multi-criteria sorting problem and was analyzed using the outranking MCDA method ELECTRE TRI. Using this method this thesis also introduces a framework to assess the environmental sustainability performance of a DC. Other contributions in this thesis are the proposal of a new metric to evaluate the DC efficiency considering the climate region of the DC location and a characterization of the current landscape of DCs in Portugal.

Research Summary:Energy is a crucial input to almost all economic activities, in addition to supporting human development efforts. The energy planning (EP) activity is a principal step in the development of an energy strategy. EP objectives which are specific to the local context may aid in ensuring the implementability and sustainability of energy plans and policies. The purpose of this research was to identify EP objectives specific to the local context of developing countries, together with their respective operational attributes, and to structure these within a transparent multi-objective decision making methodology at the national level. A national energy system model was constructed to support the EP methodology. The Economic Community of Western African States, and Ghana specifically, served as a representative area of study. The results may support successful energy strategy formulation.

Thesis Title: Evaluation of the impact of new vehicle and fuel technologies in the Portuguese road transportation sector
Thesis abstract:
The road transportation sector faces increasing energy, emissions and congestion challenges. This research work performed an integrated analysis on the energy and environmental impacts of different choices for the road transportation sector, in order to assess the possible evolution pathways for the future.
A methodology was developed in order to estimate yearly evolution of the road transportation sector and the impacts in terms of energy consumption and local and global emissions. Additionally, decision support scooping maps were also developed in order to understand the minimum and maximum energy and emissions bounds for the road transportation and to identify the main drivers influencing this sector.
In a full life-cycle approach, the BAU presented a 30% increase in energy consumption and 18% increase in CO2 emissions in 2050 compared to the 1990 value. The minimum limit was obtained considering a low population and fleet profiles, with mobility reductions happening, in an hydrogen or electricity powered vision and a high shift to alternative vehicle technologies and allowed a 52% reduction in 2050 compared to the BAU for energy consumption and 64% for CO2 emissions. If an option of high population, high vehicle density fleet profile, without mobility reduction, in a vision that does not shifts to alternative vehicle technologies was considered a maximum 32% increase in 2050 compared to the BAU both for energy and CO2 was observed.

Research topic/area: Simulation of Large Scale Application of Residential Energy Management Systems in the Electricity Grid
Research Summary: The outcome of this research consists in the development of a methodology and a tool to evaluate the energy and power resources that can be made available by the large deployment of a Residential Energy Management System (REMS) based on the Energy Box.
The Energy Box was proposed, by Livengood and Larson in the Service Science Journal in 2009, as a 24/7 background processor operating on a local computer, managing a dwelling electrical energy usage taking into consideration the homeowners preferences and desired comfort level.
This research is inserted in the development of a PhD Thesis at the University of Coimbra and also in the collaborative scope of the Energy Box Group comprising researchers of the Institute for Systems Engineering and Computers at Coimbra, the Institute of Cognitive Psychology, Vocational and Social Development and the Massachusetts Institute of Technology.
Research Interest: The Energy Box concept will be studied, as an instrument to assess the attractiveness to the distribution system operator, among other agents, to promote the installation or use of REMS.
The study will evolve to provide simulation scenarios in order to determine the Energy Box value under different conditions of, e.g., penetration, resource use, load controllability, type of consumers, season of the year and electricity price.

Thesis Title: Energy Efficiency Monitoring and Management to Promote Sustainable Behaviors
Thesis Abstract: Smart buildings are expected to extend beyond just simple automation to include advanced automatic management systems capable of interacting in real-time. This research focuses on of enhancing the heating, ventilation and air conditioning system. Considering that tenants tend to forget to adjust the operation of this system appropriately and that, in many spaces, the conditioning requirements are not adjusted to the context of those spaces, the result is unnecessary energy waste. An optimal supervisory control for such a system should consider the cost of energy, activity schedules, occupancy patterns, the individual preference of each user, and any other information that might contribute to increase performance. The result will be an adaptive controller that learns the statistical regularities of the environment and operates to meet comfort requirements, while optimizing energy costs.Smart buildings are expected to extend beyond just simple automation to include advanced automatic management systems capable of interacting in real-time.

Thesis Title (2013): Energy and exergy assessments for an enhanced use of energy in buildings
Thesis abstract: Exergy analysis has been found to be a useful method for improving the conversion efficiency of energy resources, since it helps to identify locations, types and true magnitudes of wastes and losses. It has also been applied for other purposes, such as distinguishing high- from low-quality energy sources or defining the engineering technological limits in designing more energy-efficient systems. In this doctoral thesis, the exergy analysis is widely applied in order to highlight and demonstrate it as a significant method of performing energy assessments of buildings and related energy supply systems. It aims to make the concept more familiar and accessible for building professionals and to encourage its wider use in engineering practice. This thesis is divided into five main cases studies, which have different scopes and follow slightly different approaches but all with the same common objective. Case study I aims to show the importance of exergy analysis in the energy performance assessment of eight space heating building options evaluated under different outdoor environmental conditions. This study is concerned with the so-called “reference state”, which in this study is calculated using the average outdoor temperature for a given period of analysis. Primary energy and related exergy ratios are assessed and compared. Higher primary exergy ratios are obtained for low outdoor temperatures, while the primary energy ratios are assumed as constant for the same scenarios. The outcomes of this study demonstrate the significance of exergy analysis in comparison with energy analysis when different reference states are compared. Case study II and Case study III present two energy and exergy assessment studies applied to a hotel and a student accommodation building, respectively. Case study II compares the energy and exergy performance of the main end uses of a hotel building located in Coimbra in central Portugal, using data derived from an energy audit. The results show that the most energy-efficient hotel end use does not necessarily correspond to the most exergy-efficient one. A diagram including information related to primary energy demand and energy and exergy efficiencies is proposed, revealing to be a very useful tool for including in future legislation on energy performance of buildings. Case study III uses data collected from energy utilities bills to estimate the energy and exergy performance associated to each building end use. Furthermore, the building end uses are ranked by inefficiencies or exergy destruction levels, using the concept of “Exergy Destruction Ratio”. Additionally, a set of energy supply options are proposed and assessed as primary energy demand and exergy efficiency, showing it as a possible benchmarking method for future legislative frameworks regarding the energy performance assessment of buildings. Case study IV proposes a set of complementary indicators for comparing cogeneration and separate heat and electricity production systems. It aims to identify the advantages of exergy analysis relative to energy analysis, giving particular examples where these advantages are significant. The results demonstrate that exergy analysis can reveal meaningful information that might not be accessible using a conventional energy analysis approach, which is particularly evident when cogeneration and separated systems provide heat at very different temperatures. Case study V follows the exergy analysis method to evaluate the energy and exergy performance of a desiccant cooling system, aiming to assess and locate irreversibilities sources. The results reveal that natural gas boiler is the most inefficient component of the plant in question, followed by the chiller and heating coil. A set of alternative heating supply options for desiccant wheel regeneration is proposed, showing that, while some renewables may effectively reduce the primary energy demand of the plant, although this may not correspond to the optimum level of exergy efficiency. The thermal and chemical exergy components of moist air are also evaluated, as well as, the influence of outdoor environmental conditions on the energy/exergy performance of the plant. This research provides knowledge that is essential for the future development of complementary energy- and exergy-based indicators, helping to improve the current methodologies on performance assessments of buildings, cogeneration and desiccant cooling systems. The significance of exergy analysis is demonstrated for different types of buildings, which may be located in different climates (reference states) and be supplied by different types of energy sources.

Research Summary: Electric vehicles (EVs) have been promoted as an alternative to reduce greenhouse gas (GHG) emissions, fossil fuel dependence, and urban pollution caused by the transportation sector; however, a large scale adoption of EVs faces significant challenges. This research aims to develop a dynamic fleet-based life-cycle framework to assess the effects on environmental impacts of the introduction of EVs in a fleet, focusing on GHG emissions. The framework combines fleet analysis and dynamic life-cycle modelling of vehicles to investigate the displacement of conventional vehicles over time, and consequential life-cycle assessment of electricity to assess the changes induced in the electricity system due to EV charging. The analysis focuses on the case of introducing battery electric vehicles in the Portuguese light-duty fleet.

Thesis Title: Large power hybrid PV pumping for irrigation
Research summary: Agricultural irrigation is a highly consuming activity of electricity and water. Accordingly, the world of irrigation requires innovative solutions, less water and energy dependent, to face up this problem. This work aims to show the technical and economical viability of efficient and variable-free large scale PV pumping systems for irrigation allowing up to 100% renewable energy; to reduce the water consumption, using automatisms, ICT and Precision-Agriculture-based solutions; and to market uptake and market replication of a new green product consisting of PV pumping systems consuming up to 100% renewable electricity and 30% less water. To show the long-term viability of the innovation, real scale irrigation systems will be studied: a hybrid PV-diesel motor pumps for constant pressure irrigation (in Portugal) and a hybrid PV-grid connected motor pumps (in Morocco).

Research topic/area: Sustainable energy development and rural electrification
Research Summary: Rita’s PhD thesis is focused on rural electrification methodologies, more specifically, from the demand point of view. I expect to achieve not only an efficient electrification methodology by defining sustainable pathways to accomplish it, but also to work on its business model, since I am working directly with an energy services company in their remote electrification projects’ market approach. My goal is to develop a modeling tool able to estimate current and future energy demand of developing countries’ isolated communities, based on development indicators. This tool will be important for electrification projects as it helps to customize solutions for each location depending on the development status and energy resources availability. The aim is to develop a business activity of this area and this tool will give a competitive advantage, when compared to the currently available solutions.

Research topic/area: Floating Wind Turbine Modeling and Assessment
Research Summary: The current worldwide energy consumption growth requires that new sources of energy become readily available. Floating platforms for the installation of offshore wind turbines applications will enable to explore a larger range of depths and locations. The power potential of this technology is significant, as it can be installed virtually anywhere in the ocean. The wind resource is always more reliable and higher on offshore locations. However, the technology is stills the demonstration phase, relying on the knowledge from offshore oil and gas platforms and onshore wind energy. The outcome of this work should be an integrated analysis tool for the different floating offshore wind turbine concepts, with special focus on the WindFloat prototype. These kind of tools are required in order to optimize the design and operation of this future energy system.

Research topic/area: Modeling of economic development of renewable energy projects in small scale economies
Research Summary:The purpose of this research is to build models to determine the real / potential effect on economic development of renewable energy for development projects, based on growth theory and development economics. In order to accomplish so, effects of energy consumption on social and environmental dimensions of economic development –along with its productive dimension– should be evaluated, as well as synergies between them. The outcome models may help increase the predictability of project results. So these results support decisions on energy policy and help justify investment in these projects before government and international development organizations
