In France, the building sector is the largest consumer of energy and accounts for about 43% of the total energy consumption. The building sector offers significant potential for improved energy efficiency through the use of high-performance insulation and energy-efficient systems. For existing buildings, renovation has a high priority in France because these buildings represent a high proportion of energy consumption and they will be present for decades to come. Nowadays, there is a growing interest in the so-called super-insulating materials, such as Aerogels. The objectives of this study are to examine the thermal behavior of buildings and to foster energy efficiency through the use of a newly developed aerogel-based insulating coating as well as the use of renewable energy sources, specifically solar energy. Firstly, the thermal and hygrothermal performance of exterior walls having different layer composition structures are examined. Secondly, the heating energy demand as well as the risk of summer overheating is examined for different construction periods and under different climates. Also, a mathematical model is built and compared to experimental measurement of a recently built full-scale house. Finally, the potential to decrease the heating load by adopting a closed wall loop system is scrutinized. The latter is a proposed system to capture some of the solar energy falling on the south facade available during non-cloudy winter days and transfer it to the north facade through water pipes embedded in the aerogel-based coating

With the development of society, the demand for energy saving and carbon emission reduction in buildings as well as the indoor thermal and humidity environment comfort is gradually increasing. Using Phase change materials (PCMs) or bio-based hygroscopic materials as building envelopes are promising solutions. PCMs can improve indoor thermal comfort and reduce energy consumption, while bio-based hygroscopic materials are environment-friendly materials that enable indoor humidity regulation and thermal insulation. However, only a few studies have explored the integrated application of the two types of materials and comprehensively analyzed the energy and hygrothermal performance. This dissertation proposed a passive envelope solution that integrates PCM and bio-based hemp concrete (HC) to simultaneously improve the energy, thermal, and hygric performances of buildings. The main objectives of this study are to investigate the feasibility of the integrated envelopes, to comprehensively study the hygrothermal and energy performance as well as the advantages and disadvantages of different configurations with PCM placed in different locations of the HC, and to conduct the parametric analysis and evaluate the application risks of the integrated envelope.First, experiments were conducted by comparing the hygrothermal performance of a reference envelope (HC only) and three integrated envelopes with PCM placed in different locations under two typical boundary conditions. The results demonstrated the feasibility of the integrated envelopes. The presence of PCM increased the thermal and hygric inertia of the envelope. As a result, the time delay was increased and the temperature/relative humidity amplitude was decreased. Different configurations had different advantages and disadvantages. The configurations with PCM placed in the middle of the HC was worth noting as it had small temperature/relative humidity fluctuation, long temperature time delay, and large energy savings.Then, the mathematical model of the integrated envelope that couples heat and moisture transfer and considers the temperature dependence of HC’s hygroscopic characteristic was developed. The accuracy of the model was validated by comparison with the experimental data. Based on the validated model, the simulations were performed in a Mediterranean climate to comprehensively investigate the hygrothermal and energy performance of the integrated envelope. The results highlighted the indispensable role moisture transfer plays in determining the indoor hygric environment and heat load, as well as the valuable effect of the integrated envelope on improving both energy and hygrothermal performance. Besides, the integrated envelope with PCM close to (but not in contact with) the interior showed great potential for saving energy and adapting to climate humidity variation while guaranteeing moisture equilibrium within the HC.Finally, the parametric analysis was performed from the perspective of PCM properties (thickness, latent heat, and phase transition range), and the application (condensation and mold growth) risk was evaluated. The results of the parametric analysis illustrated that the performance of the integrated envelope could be improved by increasing the thickness and latent heat and identifying the appropriate phase transition range of the PCM. The risk evaluation results confirmed that the integrated envelope was free from the risk of condensation and mold growth

Recently, low cost housing thermal performance standards were developed and approved in Brazil. These standards establish requirements and criteria that low cost housing must satisfy. However, the approach used generally deals with climatic conditions and the evaluation is based on analysis of individual components. This approach cannot express the real thermal behaviour of housing. This study presents a thermal performance evaluation method for low cost single-family one-floor housing considering the climatic conditions of Porto Alegre, Brazil. The method aims toward a global evaluation of housing through requirements and criteria that complement the standards approved recently and it considers mathematical procedures that can be easily applied by government agents involved in this task. Inner surface condensation, global flow heat coefficients, thermal inertia, among others, obtained from literature, are proposed. Four low cost houses built in Porto Alegre, considered to be references according to social and economic local reality, were evaluated through the method. Government agents involved in the project, design, financing, building, overseeing and evaluation of low cost housing in Porto Alegre and experts from research institutes in Brazil also gave their opinions of the method. Three degrees of performance for housing, in accordance with availability of government resources, are defined. The method can be used as an evaluation of possible solutions, thereby aiding decision makers.

O alto consumo de energia dos centros de dados tem sido foco na maioria das pesquisas recentes. Em ambientes de nuvem, v?rias solu??es est?o sendo propostas com o objetivo de alcan?ar efici?ncia energ?tica, que v?o desde o dimensionamento da frequ?ncia de processadores, da utiliza??o de estados suspens?o, at? a consolida??o de servidores virtuais. Embora estas solu??es permitam redu??o no consumo de energia, apresentam impacto sobre o desempenho das aplica??es. Visando resolver esta limita??o, n?s apresentamos uma orquestra??o de diferentes t?cnicas e mecanismos de economia de energia, com a finalidade de melhorar o balanceamento entre economia de energia e desempenho das aplica??es. Para este fim, implementamos o e-eco, um sistema de gest?o que atua juntamente com a plataforma de nuvem, decidindo qual estado de suspens?o pode ser melhor aplicado sobre os servidores, al?m de escolher a melhor op??o entre consolida??o de servidores ou dimensionamento de frequ?ncia dos processadores. Para avaliar o e-eco, testes foram realizados em ambientes de nuvem real e simulado, utilizando aplica??es scale-out em uma infraestrutura de nuvem din?mica, levando em considera??o transa??es-por-segundo como m?trica de desempenho. Os resultados mostraram que nossa proposta apresenta a melhor rela??o entre economia de energia e desempenho de aplica??es em ambientes de nuvem, quando comparada com outros trabalhos apresentados na literatura.
The high energy consumption of data centers has been a recurring issue in recent research. In cloud environments, several solutions are being used that aim for energy efficiency, ranging from scaling the processors frequency, through the use of sleep states, to virtual machine placement mechanism. Although these solutions enable the reduction in power consumption, they usually impact on the application performance. To address this limitation, we present an orchestration of different energy-savings techniques and mechanisms to improve the trade-off between energy savings and application performance. To this end, we implemented the Energy-Efficient Cloud Orchestrator ? e-eco ? a management system that acts along with the cloud platform, deciding which sleep state can be better applied on hosts, in addition to choosing the best option between virtual machines consolidation and dynamic processor frequency scaling. To evaluate e-eco, tests were carried out in a real and a simulated environment using scale-out applications on a dynamic cloud infrastructure, taking into account transactions per second as a performance metric. Results showed that our proposal presents the best improvement on the trade-off between energy savings and performance applications for cloud environments when compared with other works presented in the literature.

It is necessary for large companies to understand and be able to adapt to the industrial Transformation towards an increasing focus on energy efficiency, which takes place today. The Energy Efficiency Directive (EED)issued by the European Union has enlarged the focus on working with energy efficiency within large companies. Further, the Swedish government has introduced the law about energy auditing in large companies, which is based on the EED. These regulations encourage companies to develop a management system that includes requirements on conducting energy audits and propose cost Deffective measures. Energy efficiency is already an important aspect within many companies environmental work, however a more developed and systematic approach to energy efficiency than most companies already have is needed in order to fulfill the legal requirements. The Company investigated in this study is one the worlds leading technology companies with more than 9000 employees in Sweden. Currently, they have energy as a significant aspect in their environmental work according to the international management system standard ISO 14001. Today they are also developing their energy work by conducting energy audits in order to comply with the new legislation. This gives a mor detailed view of the energy use and potential improvements that can be done, but in order to ensure continual improvements over a long period of time further measures are needed. Within this study it was investigated what measures a large company needs to implement in order to increase their energy performance and comply with the legislation. By a literature review focusing on management systems as well as interviews within the Company, a complementary study with two companies covered by the EED and three expert interviews, five key factors were identified. These factors are, top management commitment, awareness, goals, measurements and evaluation. A model was then developed aligning these factors. Further, concrete proposals for action to manage these factors were presented. By!increasing focus on these key factors and implement proposed measures companies will increase their energy performance and also make the organization aware of how actions affect a company’s energy performance

Building energy simulation is an important tool for evaluating the energy consumption of a building and can provide guidance in the design of a building and its mechanical systems. EnergyPlus is a new energy simulation program meant to be a major advance over existing energy simulation programs. This study uses EnergyPlus to compare several alternative low-energy cooling systems for an office building in suburban London and compare them to the chilled ceiling system installed in the actual building. Prior to modeling the full -scale building, several validation studies demonstrate the accuracy of EnergyPlus and the author's competency as an EnergyPlus user. Systems considered include displacement ventilation, traditional mixing variable air volume ventilation, night cooling, and natural ventilation. Several changes were made to the EnergyPlus source code to model these systems appropriately. Most notable are a displacement ventilation three-node vertical temperature gradient model and a simple model for prediction of the natural ventilation rate. A detailed building model is created from inputs gathered from both building design documents and measured data. An excellent comparison between simulated and measured space temperatures over a one-month period demonstrates the accuracy of the model. System comparisons show that systems using free cooling from outside air and night cooling use the least energy and have the smallest equipment. Natural ventilation alone is insufficient to maintain summer comfort within the building, but could be used within a hybrid ventilation system. Conclusions are that EnergyPlus should be adopted for general use, because it represents a major improvement over previous energy simulation programs and is capable of modeling real-world buildings. A hybrid ventilation system would have the lowest building system energy use, but displacement ventilation is also a good choice, and could be implemented with few changes to the existing building.

As redes de sensores sem fio se constituem numa área que outorga grandes oportunidades para a oferta de uma série de aplicações inovadoras e com baixo custo. Os dispositivos destas redes são bastantes pequenos e sua fonte de alimentação são baterias. O tempo de vida destas é limitado, limitando assim o tempo da vida dos sensores e da rede como um todo. Por esta razão nos últimos anos o tema de eficiência energética tem atraído grande interesse de pesquisadores. O aumento do custo da energia e do consumo global da energia pelo setor de ICT (Information and Communications Technologies) têm crescido vertiginosamente devido ao aumento continuo do número de clientes e da demanda por aplicações de maior complexidade. Por tudo isso têm sido desenvolvidos distintos métodos e técnicas para economizar energia nas RSSF. Neste trabalho se implementam dois algoritmos que levam em conta critérios para economizar os custos de energia da rede e através de experimentos de simulação se avalia os mesmos. Nos resultados pode se observar as vantagens de trabalhar com sistemas que visam a eficiência energética.
The WSNs (Wireless Sensor Networks) belong to an area that gives rise to great opportunities to spread innovative and low cost applications. These kinds of networks are composed of tiny devices with limited energy. The main source of power supply for WSNs are batteries, which are limited in cycle life, thus limiting the sensors lifetime and the network as a whole. Due to that fact, the energy efficiency network is becoming the main concern to be addressed by researchers. Rising energy prices and global energy consumption by the ICT (Information and Communications Technologies) sector have grown dramatically due to the continuous increase in customer number and the demand for more complex applications. For the reasons outlined above, different energy-saving techniques for WSNs have been developed. Two energy-saving algorithms for WSNs were implemented in this thesis, and they were tested by experimental evaluation using simulation. The results obtained from the simulations showed the advantages of working with systems aiming at energy efficiency.

Ph.D.
The continuous growth in computing capability has expedited the scientific discovery and enabled scientific applications to simulate physical phenomena for increased problem sizes. However, as the computing capability escalates, power constraints are becoming a first-order concern for high performance computing (HPC) facilities. For example, the U.S. Department of Energy has set a power constraint of 20 MW to each exascale machine. How to achieve the target performance under power constraints remains to be an issue. Therefore, efficient operation of these facilities requires power constraints to be taken into account at all layers, which potentially impacts the performance and energy efficiency. In order to improve the performance and energy efficiency for computing and storage resources under power constraints, I proposed the following three techniques. First, I developed a power-aware checkpointing model through exploring the interplay among power capping, temperature, reliability, performance, and energy efficiency. Applying the model leads to maximized performance and energy efficiency, and minimized data movements over storage systems. Second, I characterized the performance and energy efficiency of HPC workflows on heterogeneous processors. In addition, I also characterized how scientific simulation and analysis react to power capping differently and how they vary based on error resilience. Based on the characterization of HPC workflows, I developed a reliability-aware platform configuration model to determine the optimal platform configuration which includes power allocation and distribution, power capping levels, and computing scales for power-constrained HPC workflows. Third, I developed a proactive burst buffer draining scheme to minimize the I/O provisioning requirement of permanent storage systems while preserving the system I/O performance. Facing power constraints, reducing the storage provisioning level directly decreases the power consumption of storage systems. Applying the proactive burst buffer draining scheme minimizes the storage provisioning level and power consumption without compromising the storage I/O performance.

La eficiencia energética es un gran reto en el área de la Supercomputación (HPC), las grandes necesidades de energía no solo limitan el potencial de las computadoras de nueva generación, sino que también aumentan el coste de funcionamiento de estos sistemas. Mientras que los sistemas HPC tienden a ser cada vez más energéticamente proporcionales en un empeño por reducir costes, los enlaces de interconexión siguen siendo muy ineficientes. Los enlaces de interconexión comunes funcionan en modo "always-on", es decir, consumiendo energía incluso cuando no transmiten. Aunque se han propuesto algunas técnicas que ayuden a la proporcionalidad energética de los enlaces de interconexión, éstas han sido muy agresivas o poco enfocadas hacia su uso con sistemas HPC. Las técnicas de ahorro energético para los enlaces más agresivas no suelen ser utilizadas en HPC, particularmente porque degradan excesivamente el rendimiento. Cualquier técnica de ahorro energético solo será adoptada en sistemas HPC si no hay un impacto excesivo en el rendimiento, el cual es el principal objetivo de estos sistemas. En esta tesis, primeramente se presenta una nueva caracterización de aplicaciones HPC, remarcando el enorme potencial de la proporcionalidad en los enlaces de interconexión proporcionales para aplicaciones HPC. Seguidamente, se evaluará siguiendo el protocolo "IEEE Energy Efficient Ethernet" un link de interconexión on/off. Esta evaluación presentará una relación de impacto energético y rendimiento en aplicaciones HPC, enfatizando en la necesidad de usar un enlace de interconexión enfocados a la eficiencia. Se continuará con la presentación de un mecanismo adaptivo, PerfBound, que ahorra energía respetando unos límites máximos de impacto en el rendimiento. Finalmente, esta estructura es aplicada a un nuevo estado intermedio de funcionamiento adicional a los estados tradicionales on/off. Los resultados de este estudio, muestran que en más de 15 aplicaciones HPC la energía en los enlaces puede ser reducida en un 70% en comparación con enlaces "always-on", mientras que el impacto en el rendimiento es de tan solo un 1%.
