The MIT community has embarked on an initiative to the reduce energy consumption and in accordance with the Kyoto Protocol. This thesis seeks to further expand our understanding of how the MIT campus consumes energy and with that knowledge be able to recommend methods of reducing energy consumption by minimizing and even eliminating careless energy use. The largest energy consuming building per square foot, Building 39, was selected and analyzed in detail. This thesis proves the unnecessarily high airflows and irresponsible fan use are the source of Building 39's wasteful consumption of energy. Research revealed that the recirculating fans drew the most energy and were continuously running on full power. If the fans were turned down during off peak times the consumption of electricity could be decreased by as much as approximately 26% and save the Institute $250,000 a year in electrical costs.

With the unprecedented amount of data collected by smart meters, we have opportunities to systematically analyze the energy consumption patterns of households. Specifically, through using data analytics methods, one could cluster a large number of energy patterns (collected on a daily basis) into a number of representative groups, which could reveal actionable patterns for electric utilities for energy planning. However, commonly used clustering approaches may not properly show the variation of energy patterns or energy volume of customers at a neighborhood scale. Therefore, in this thesis, we introduced a clustering approach to improve the cluster representation by preserving the temporal shapes and energy volume of daily profiles (i.e., the energy data of a household collected during 1 day). In the first part of the study, we evaluated several well-known clustering techniques and validation indices in the literature and showed that they do not necessarily work well for this domain-specific problem. As a result, in the second part, we introduced a two-stage clustering technique to extract the typical energy consumption patterns of households. Different visualization and quantified metrics are shown for the comparison and applicability of the methods. A case-study on several datasets comprising more than 250 households was considered for evaluation. The findings show that datasets with more than thousands of observations can be clustered into 10-50 groups through the introduced two-stage approach, while reasonably maintaining the energy patterns and energy volume of individual profiles.

With world energy demand on the rise and greenhouse gas levels breaking new records each year, lowering energy consumption and improving energy efficiency has become vital. MIT, in a mission to help improve the global energy system, launched the MIT Energy Initiative in 2006, and is aggressively trying to improve campus-wide energy consumption. MIT has also teamed up with the NSTAR utility company and pledged to reduce electricity generation by 15% by 2013 to serve as a model for others to follow. This thesis presents a measurement of the current performance of the most recent energy practices and seeks to provide a direction for future improvements. Following energy consumption over the course of the past decade, energy performance for the MIT campus and its buildings could be observed. It was determined that the majority of efforts to improve energy efficiency have been successful. Improvements to the campus' largest consuming laboratory buildings have significantly reduced consumption, and new energy projects have provided millions of dollars in yearly savings. Behavioral projects have not yet shown widespread success across campus but have had a drastic reduction effect in student residences where energy consumption has decreased 23% since 2006. Many buildings, which are not the largest energy consumers on campus, are continuing to increase consumption and need to radically improve for MIT to decrease overall consumption.

Full textDenna rapport avhandlar ett examensarbete där flera metoder har studerats för att förbättra energikonsumptionen för ett elektriskt fordon med två permanentmagnetsynkrona motorer. Två fördelningskartor för drivande moment är framtagna baserat på effektivitetskartor och lastöverföring. Fördelningskartorna för drivande moment som är baserat på effektivitet visar upp till 8,94% energiminskning. Två olika regenerativa bromsstrategier är framtagna och jämförda. Båda strategierna har ren regeneration vid låga decelerationer och är reglerat genom modifierat gaspedalsmappning. Strategi 1 ger inte mer regeneration när bromspedalen trycks ned och är då enklare medans strategi 2 kan blanda in mer vridmoment från elmotorn. Bakaxelstyrning är också studerat i termer av dess bidrag till energikonsumption samt en LQR regulator är utvecklad för reglering av fordonets bakaxelstyrning.

Full textBlockchain är en så kallad distribuerad huvudbok teknologi som fick ett stort genombrott med den populära blockchain applikationen Bitcoin i 2009. Teknologin möjliggör upprätthållandet av en digital och offentlig huvudbok som är decentraliserad, vilket betyder att ingen ensam person eller organisation äger och kontrollerar den offentliga huvudboken. Huvudboken i blockchain är uppbyggt som en kedja av block, dessa block är datastrukturer som innehåller information. Huvudboken distribueras i ett nätverk av datorer som kallas för noder, dessa noder ägs av en eller flera personer. Problemet är att alla noderna i nätverket måste ha identiska huvudbok. Detta problem löses med en uppsättning av regler som noderna måste följa, denna uppsättning kallas för konsensus mekanism. Konsensus mekanismer säkrar huvudboken genom att möjliggöra en överenskommelse bland majoriteten av noderna om huvudbokens innehåll, och ser till att oärliga noder inte kan påverka majoritetens överenskommelse. Det finns flera olika konsensus mekanismer. Ett problem med konsensus mekanismer är att de är tvungna att göra en avvägning mellan låg energianvändning och hög säkerhet. Syftet med denna rapport är att undersöka och utreda relationen mellan energianvändning och säkerhet i konsensus mekanismer. Målet är att utföra en komparativ analys av konsensus mekanismer utifrån energianvändning och säkerhet. Konsensus mekanismerna som jämförs är Proof of Work, Proof of Stake och Delegated Proof of Stake. Metodologin som används är litteraturstudier och komparativ analys med hjälp av existerande metoder och data från applikationer som använder konsensus mekanismerna. Resultatet visar att Proof of Work väljer hög säkerhet på bekostnad av hög energianvändning, medan Proof of Stake och Delegated Proof of Stake väljer låg energianvändning men på bekostnad av lägre säkerhet. Analysen ger en ny inblick som visar att centralisering är en oundviklig faktor som hotar säkerheten.

In the area of wireless communications, energy consumption is the key design consideration. Significant effort has been placed in optimizing hardware for energy efficiency, while relatively less emphasis has been placed on software energy reduction. For overall energy efficiency reduction of system energy consumption in both hardware and software must be addressed. One goal of this research is to evaluate the factors that affect software energy efficiency and identify techniques that can be employed to produce energy optimal software. In order to present a strong argument, two state-of-the-art low power processors were used for evaluation: the Intel StrongARM SA-1100 and the next generation Intel Xscale processor. A key step in analyzing the performance of software is to perform a comprehensive tabulation of the energy consumption per instruction, while taking into account the different modes of operation. This leads into a comprehensive energy profiling for the instruction set of the processors of interest. With information on the energy consumption per instruction, we can evaluate the feasibility of energy efficient programming and use the results to gain greater insight into the power consumption of the two processors under consideration. Benchmark programs will be tested on both processors to illustrate the effectiveness of the energy profiling results. The next goal is to look at the leakage current and current consumed during idle modes of the processors and how that impacts the overall picture of energy consumption. Thus energy consumption will be explored for the two processors from both a dynamic and static energy consumption perspective.

The 3G wireless interface is a significant contributor to battery drain on mobile devices. This paper describes the design, implementation, and experimental evaluation of methods to reduce the energy consumption of the 3G radio interface. The idea is to put the radio in its "Low-power idle" state when no application is likely to need the network for some duration of time in the future. We present two techniques, one to determine when to change the radio's state from "Active" to "Low-power idle", and the other to change the radio's state from "Low-power idle" to "Active". The technique for switching to Low-power idle mode is well-suited for the emerging "fast dormancy" [3, 4] primitive that will soon be common on smartphones. We demonstrate using an implementation and a trace-driven evaluation based on the measurement and trace collected from HTC GI and Samsung Nexus S phones over various combinations of seven different background applications that our methods reduce the energy consumption of the 3G interface by 36% on average compared to the currently deployed scheme on the T-mobile network. In addition, if applications are able to tolerate a delay of a few seconds when they initiate a session, our methods reduce energy consumption by 52% on average, with a mean increase in delay of 6.46 seconds.

Full textHoje em dia assistimos a uma grande pressão e esforço no sentido de estimular a conservação de energia, seja devido a limitações económicas, preocupações ambientais, ou normas regulatórias. No topo do consumo de energia está a energia sob a forma de electricidade Para se conseguir incentivar a utilização eficiente da energia é necessário fornecer consciencialização energética. Se os consumidores de elecricidade tiverem acesso a informação detalhada sobre como, quando e que aparelhos estão a consumir energia, estes poderão tomar boas e bem suportadas decisões e anuir mudar os seus hábitos de modo a reduzir o consumo de energia, e por fim, gastar menos dinheiro. O projecto aqui apresentado desenvolve as bases para um aparelho que fornece informação detalhada sobre o consumo de energia eléctrica para uma casa. A informação a ser fornecida deverá ser separada individualmente para virtualmente cada aparelho singular presente. A técnica escolhida para desenvolver o aparelho foi Monitorização Não Intrusiva de Cargas de Aparelhos. A partir de um único ponto de medida o sistema deverá identificar as cargas individuais na casa, o que faz com que o hardware tenda a ser simples e minimal, recaindo a complexidade para o software. O sistema desenvolvido deverá ser de baixo custo e de fácil instalação. O sistema que foi desenvolvido foi capaz de identificar individualmente e com grande sucesso os aparelhos presentes num ambiente controlado. Ao contrário de outros sistemas deste tipo, o sistema apresentado nesta dissertação é capaz de distinguir cargas eletricamente idênticas, através do uso da técnica de Medição Indirecta de Potência implementada através de uma Rede de Sensores Sem Fios.
Nowadays we witness a great pressure and effort in order to stimulate energy conservation, either due to economic constraints, environmental concerns, or regulatory pressures. At the top of the energy consumption is the consumption of energy in the form of electricity. The first step to improve energy utilization efficiency is energy awareness. So if there is some manner to provide the average person information about how he is consuming electricity, he may take it by its own interest, and In fact, if electricity consumers have access to detailed information about how, when and by which devices energy is consumed, they can make good and well supported decisions on how they can change their habits to spend less energy and ultimately spend less money. The project hereby presented, develops the basis for a device that provides detailed information on electrical energy expenditure for a home. The information to be provided aims to be disambiguated for virtually every individual appliance present. The chosen technique to develop such a device was Non-Intrusive Appliance Load Monitoring. The system identifies individual loads from a single measurement point. That makes that the hardware tends to be simple and minimal, passing the complexity to the software. The system aims to be very low cost and easy to deploy. The system developed was able to identify with great success individual appliances in the total load on a controlled environment. Unlike other systems of this type, the system presented in this dissertation has the ability of disambiguating electrically identical loads, by the use of the technique of Indirect Power Sensing deployed with a Wireless Sensor Network

Full textIn the recent years, more importance has been given to the energy consumption issue in telecommunication networks and mobile operators are rethinking their network design for optimizing its energy efficiency. In this thesis, we propose schemes for optimizing the energy consumption of mobile access networks. We begin by proposing energy-aware Radio Resource Management (RRM) schemes and show that a load balancing between available resources gives some energy savings. However, these gains remain small as a large part of the energy consumption is load-independent. We thus propose sleep mode schemes of resources in the network (cells or carriers) and show that they give a large gain when traffic is low. We then propose optimal sleep mode controllers that give, for each traffic scenario, the best actions to take in each state of the network. We make two observations: the first is that activating a new resource is not instantaneous, leading to QoS degradation if a conservative policy is not considered, and the second is that a ping-pong effect may appear at the frontier between two capacity regions. We adapt our controllers to take into account these imperfections, and show how to derive the optimal policy using Markov decision theory. We then extend our works to the case of small cell deployment in heterogeneous networks, composed of macro and small cells base stations. We study the capacity and power consumption of these networks and show that the energy efficiency is increased for some deployment strategies when the power consumption of small cells is low. We then propose sleep mode for small cells and develop optimal sleep/wakeup schemes based on the information on traffic load and user localization in the cell, in the cases where this information is complete, partial or delayed. We show that these sleep mode schemes achieve large energy consumption gains

The intent of this report is to recommend a process for legislation that can be used to identify commercial buildings that have the greatest potential to reduce energy consumption. A point-based evaluation is completed of current energy processes for existing commercial buildings. The recommended energy evaluation system is applied to an existing building, which allows for a detailed review of how the evaluation is completed for a building. The results are presented to display the value of assessing building energy performance. Additionally, the results reinforce the potential to transform the industry and energy use by buildings.

Full textIn 2007, vacation rental properties in the United States accounted for more than 22% of the domestic lodging market. These properties are a unique segment of the lodging industry due to their residential design and commercial use. Coastal vacation rental properties represent the largest supply, demand and value of the nation's vacation rental supply. In the case of North Carolina's Outer Banks, tourism is the area's largest source of income, with vacation real estate agencies being the largest accommodation provider. This study uses a multiple regression analysis to investigate the energy consumption of 30 vacation rental homes on Hatteras Island. Hatteras Island's abundant supply of vacation rental homes provided a diverse sample to study energy consumption with a wide range of houses regarding size, age, and location. Since very little research has been conducted on the energy consumption of vacation rental homes, this study aims to contribute detailed information regarding the energy consumption of unique accommodation sector.

In this thesis, we evaluate the feasibility of exposing elements in a processor's datapath to the compiler in order to reduce energy consumption. We focus on eliminating register file traffic by exposing the latches in the bypass network, as our study shows that there is potential for significant benefit by doing this. We present the idea of software restart markers to handle the exception management overhead that results from exposing additional processor state. We then implement our proposed techniques and observe an average energy savings of 7.0% across a range of benchmarks when compared to a low-power MIPS processor. We also explore the implications of changing the pipeline structure to both improve performance and expose more machine state.

Full textAs a University that has been low rated amongst government agencies 2009, today KTH has a vision to become one of Europe’s leading universities in sustainable development. The aim with this paper is to investigate the energy consumption at KTH from a systems perspective. Another purpose is that the result could be used as a guideline for future work. The paper involves mapping of the energy consumption in the schools of KTH and a description of the current state regarding the energy work. Further, an interview survey has been performed in order to achieve a better understanding of how Akademiska Hus and KTH relates to the energy topic. The mapping shows that all schools shows a reduction in their energy consumptions, where ABE by the year 2015 has an energy consumption of 3988 MWh which is a decrease by 30 % compared to 2011 (5690 MWh). The lowest reduction is shown by ICT which counts to 8 %. The total energy consumption coming from facilities at KTH is counted to approx. 188 GWh. The result of this paper shows that the environmental work of KTH have not been on a satisfying level and that the current rental model between KTH and Akademiska Hus does not encourage progress in the energy topic at KTH. Further, it is proven that Akademiska Hus and KTH have different levels of ambition in the energy matter, and that the energy reporting tool that is provided to KTH has clear improvement potentials, where a distinction between property – and operation electric is one of them. This would allow clearer follow-ups of the energy goals in KTH, which is not the case today. A summary of improvement suggestions from the conclusions of the study are: Create a counterpart at KTH to the energy strategist at AH that could facilitate the communication between the parties and highlight the energy issues at KTH. Start a discussion concerning the rental model and improve it, to create incentives for energy savings mainly at the KTH side. Develop and introduced an improved energy reporting tool.

Full textIn view of the current global scenery, in which several nations are striving against global warming, energy efficiency rises as a cost-effective prospect. As the building sector accounts for over one-fifth of the total delivered energy consumed worldwide, it has great potential for implementing rationalization and energy efficiency measures. Service buildings are expected to have the highest growth in energy consumption when compared to residential buildings and are therefore the focus of this thesis. Energy reduction efforts for service buildings are vast; however, they are concentrated mostly on technological opportunities. Behaviour changes represent a great potential for reducing energy consumption without significant financial costs, but still, they are commonly disregarded. Hence, the present dissertation aims to propose a quantitative methodology to analyze occupants’ behaviours and their impact on energy consumption in service buildings. Results are acquired through the use of dynamic simulation, namely DesignBuilder software. Energy consumption due to behaviour is determined by simulating the occupant interactions with equipment, lighting and HVAC systems. To that end, three occupancy profiles were fixed: standard occupants’ interactions are defined by Decree-Law nº 79/2006; efficient occupants have extreme efficient behaviours leading to energy savings; inefficient ones lead to extreme energy waste. Dynamic simulation results give evidence of the occupancy impact on energy consumption. Efficient behaviours were able to reduce energy consumption by over 34%. However, regardless of the rigorousness of efficient behaviours, waste potential by inefficient occupants was always higher than saving potential. This result highlights the importance of understanding occupant behaviours and its accurate consideration of dynamic simulation tools.
No atual cenário mundial, no qual diversas nações lutam contra o aquecimento global, a eficiência energética se destaca como uma opção viável. O setor de edifícios é responsável pelo consumo de mais de um quinto da energia total gerada, e por isso possui grande potencial para a implementação de medidas de racionalização e eficiência energética. Espera-se que os edifícios de serviços tenham o maior crescimento no consumo de energia quando comparados aos edifícios residenciais, e, portanto, são o foco desta tese. As possibilidades de redução de energia para os edifícios de serviços são vastas; no entanto, estas se concentram principalmente em oportunidades tecnológicas. As mudanças de comportamento representam um grande potencial para reduzir o consumo de energia sem custos financeiros significativos, no entanto ainda são geralmente desconsiderados. Dessa forma, a presente dissertação visa propor uma metodologia quantitativa para análise dos comportamentos dos ocupantes e seu impacto no consumo de energia em edifícios de serviços. Os resultados foram adquiridos através do uso da simulação dinâmica de edifícios, pelo software DesignBuilder. O consumo de energia devido ao comportamento foi determinado pela simulação das interações entre os ocupantes e os equipamentos, sistema de iluminação e de aquecimento, ar condicionado e ventilação. Para este fim, foram considerados três perfis de ocupação: o ocupante de referência teve por base as definições do Decreto-Lei nº 79/2006; os ocupantes eficientes possuem comportamentos extremos e eficientes que levam a economias de energia; ocupantes ineficientes causam um desperdício extremo de energia. Resultados da simulação dinâmica evidenciam o impacto da ocupação no consumo de energia. Comportamentos eficientes . foram capazes de reduzir o consumo em mais de 34%. No entanto, independentemente do rigor dos comportamentos eficientes, o potencial de desperdício de energia pelos ocupantes ineficientes foi, em todos os casos, superior ao potencial de economia energética pelos ocupantes eficientes.Este resultado destaca a importância de compreender os comportamentos dos ocupantes e assegurar sua análise de forma precisa sobre as ferramentas de simulação dinâmica.
