Data centers consume vast amounts of electrical energy to power their IT equipment, cooling systems, and supporting infrastructure. This high energy consumption contributes to the overall demand on the electrical grid and release of greenhouse gas emissions. By optimizing energy performance, data centers can reduce their electricity bills, overall operating costs and their environmental impact. This includes implementing energy-efficient technologies, improving cooling systems, and adopting efficient power management practices. Adopting new cooling solutions, such as liquid cooling and indirect evaporative cooling, offer higher energy efficiency and can significantly reduce the cooling-related energy consumption in data centres.In this work, two experimental investigations on a new cooling topologies for information technology racks are conducted. In the first topology, the rack-cooling system is based on a combination of close-coupled cooling and direct-to-chip cooling. Five racks with operational servers were tested. Two temperature difference (15 K and 20 K) was validated for all the IT racks. The impact of these temperature difference profiles on the data-centre performance was analysed using three heat rejection systems under four climatic conditions for a data centre of 600 kW. The impact of the water temperature profile on the partial power usage effectiveness and water usage effectiveness of data centre was analysed to optimise the indirect free cooling system equipped with an evaporative cooling system through two approaches: rack temperature difference and by increasing the water inlet temperature of the data centre. In the second topology, an experimental investigation conducted on a new single-phase immersion/liquid-cooling technique is developed. The experimental setup tested the impact of three dielectric fluids, the effect of the water circuit configuration, and the server power/profile. Results suggest that the system cooling demand depends on the fluid’s viscosity. As the viscosity increased from 4.6 to 9.8 mPa.s, the cooling performance decreased by approximately 6 %. Moreover, all the IT server profiles were validated at various water inlet temperatures up to 45°C and flow rates. The energy performance of this technique and the previous technique was compared. This technique showed a reduction in the DC electrical power consumption by at least 20.7 % compared to the liquid-cooling system. The cooling performance of the air- and liquid-cooled systems and the proposed solution was compared computationally at the server level. When using the proposed solution, the energy consumed per server was reduced by at least 20 % compared with the air-cooling system and 7 % compared with liquid-cooling system.In addition, a new liquid cooling technology for 600 kW Uninterruptible Power Supply (UPS) units. This cooling architecture gives more opportunities to use free cooling as a main and unique cooling system for optimal data centres (DCs). Five thermal hydraulic tests are conducted with different thermal conditions. A 20 K temperature difference profile was validated with a safe operation for all UPS electronic equipment resulting with a thermal efficiency of 82.27 %. The impact of decreasing water flow rate and increasing water and air room temperatures was also analysed. A decrease in inlet water and air temperatures from 41°C to 32°C and from 47°C to 40°C respectively increases the thermal efficiency by 8.64 %. Furthermore, an energy performance analysis comparison is made between air cooled and water cooled UPS units on both UPS and infrastructure levels

The environmental concern has given rise to various reflections in order to meet two essential requirements: reduce energy consumption and impact on the external environment, and ensure the quality and comfort of buildings. It is obvious that the solutions used today are not universal and their effectiveness depends on many factors such as the surrounding climate, the type of use, etc. The choice of materials used and the understanding of the basic physical phenomena related to the climate are essential factors for the success of the design of a building with high environmental and energy qualities. The use of bio-based materials in construction (agricultural co-products) is a rapidly developing approach worldwide that aims to limit the use of fossil fuels and reduce the energy bill. Among the new materials, those developed based on agro-resources have been the subject for several years of renewed interest and resumption of studies, highlighting their ability to regulate ambient hygric variations. However, the literature review shows that these materials have a low thermal inertia that could be improved by using the phase change material (PCM) that can absorb and release heat energy when phase change occurs depending on the imposed temperature conditions. The aim of the thesis is to study the hygrothermal performance of hemp concrete and hemp coating incorporating phase change materials for application in the building

In a context of global warming and planned end of fossil fuels, the construction industry aims to reduce by 38% its energy consumption and to achieve 10% of bio-based materials used in construction in 2020. Thus, the hemp concrete can play a major role thanks to its positive environmental impact and its hygrothermal properties that allow it to ensure a role of heat damper and comfort stabilizer. Or hygrothermal behavior of hemp concrete throughout the building is little discussed in the literature and never for commercial buildings. The main objective of this project is to fill this gap by studying and optimizing the energy performance of a hemp concrete building designed for offices and / or classrooms. To ensure inside thermal comfort, different technical solutions will be coupled to the building and compared with each other: - A double flow thermodynamical ventilation combining a heat pump with a double flow central. - A simple flow ventilation associated to a pipe system which recovers heat from the basement to preheat ventilation air in winter and cool in the summer. - A double flow ventilation associated to a Canadian well. Through computer simulation and measurements made initially at the level of components, it will be possible to evaluate the potential of each component on the energy and hygrothermal comfort of commercial buildings mainly integrating the project boundary Grand Campus Reims but also can be extended to other French specificity climates

The performance of a system must be well defined, attainable and above all measurable. This is not the case today for ventilation. On the one hand ventilation performance is usually declined on energy efficiency considerations or simply on a rough estimation of ventilation rates. The performance related to thermal comfort and IAQ are addressed separately through dedicated evaluation tools. On the other hand, the existing evaluation tools today are nowadays limited in their practical applications for in situ measurements, in particular in the case of natural and mixed ventilation. The aim of the present thesis is to examine the existing experimental technics, at full scale building in order to propose improvements on evaluation methods and commissioning protocols. The present thesis deals with ventilation performance taking into account ventilation efficiency as intrinsic performance and thermal comfort as overall performance.The first part is devoted to the in situ assessment of intrinsic ventilation performance (ventilation rates, mean age of air, and air exchange efficiency), based on decay tracer gas techniques. After a theorical analysis of the various performance indexes and their corresponding measurement techniques, an experimental study was carried out in a classroom under different ventilation strategies (mechanical, natural & mixed mode). The analysis proved the importance of the application of the tracer gas decay on ventilation rates accuracy with in particular a strong influence of measurement times and used tracer gas concentration. A methodology has been adapted and tested for the measurement of the air exchange efficiency in natural and mixed mode ventilation, by avoiding measurements in exhaust vents (a technique usually used and advocated by current standards).The second part is devoted to in situ assessment of thermal comfort under different ventilation strategies. Different methods, standards and evaluation techniques were tested and compared with occupants’ perception. The results demonstrated the presence of several inadequacies during the implementation of existing methods and standards. Mainly, it concerns the inadequacy of static methods (PMV PPD) for thermal comfort assessment in the presence of fluctuating thermal conditions, even with mechanical ventilation. Uncertainty analysis related to measurement errors has demonstrated the incoherence of current standards in the classification of comfort categories

Solar thermal systems combined with a backup system such as a boiler, a heat pump or incorporating an absorption chiller, can play an important role in reducing buildings energy consumption for heating, cooling and hot water production needs. In this sense, characterizing the energy performance of thermal systems is crucial.Currently available methods of system characterization are either based on several separate physical tests of system components to be evaluated, which do not take into account the real interactions between them, or on physical models that can be complex and difficult to identify especially because systems nowadays are compact and prefabricated in the factory. Due to the lack of a reliable method to estimate the performance of solar thermal systems before their integration into buildings, their market faces a lot of impediment to be developed.In this context, it becomes essential to develop a generic methodology that can be applied to different types of systems which overcomes the difficulties encountered by the current ones.The proposed evaluation approach in this manuscript is composed of four main steps: determining a test sequence, testing the system in a semi-virtual test bench according to predetermined sequence, data acquisition and identifying an artificial neural network (ANN) of the system and finally the model simulation in order to estimate the system consumption in the desired boundary condition. Using a completely "black box" model of the whole system using the ANN makes the methodology totally "non-intrusive". No prior knowledge about the systems internal parameters (yields, thermal conductivities, regulation etc.) is necessary to apply the proposed approach.The methodology validation was performed through several numerical experiments for seven systems coming from three different typologies. During the validation process, ANN estimates were compared with calculations of physical models in several different conditions (quality of building, climate and collector area). The developed approach was applied to five real systems as well. The application results allowed the confirmation of the methodology relevance

The global context of energy savings and greenhouse gases emissions control led to significant efforts in France to boost the thermal insulation in buildings in order to reduce heating consumption. Nevertheless, the stated thermal performance before construction or refurbishment is rarely achieved in practice, for many reasons (calculation errors, defects in materials or workmanship, etc.). Yet, guaranteeing the real thermal performance of buildings on the spot is crucial to enhance the refurbishment market and the construction of energy efficient buildings. To do so, measurement techniques of the intrinsinc thermal insulation performance indicators are needed. Such techniques already exist worldwide, and consist in processing the measurement data from the indoor and outdoor thermal conditions and the heat consumption. Some of them have already proved themselves in the field, but are either binding or very imprecise. And above all, the related uncertainty calculations are often rough. The objective of this thesis funded by CSTB is to consolidate a novel measurement method of the thermal insulation quality of a whole building after reception of work (ISABELE method). In the first chapter, a state of the art of the existing methods allows to identify possible ways to pursue this goal from a comparative synthesis. The primary reflection is about the uncertainty calculation method (which is a central issue). The second chapter presents a global methodology to combine the propagation of random and systematic errors from bayesian and classical approaches. One of the most important uncertainty sources deals with the infiltration air flow evaluation during the test. The third chapter investigates the characterization of this uncertainty, as well as its impact on the final result, depending on the chosen experimental approach (rule of thumb, simplified aeraulic models, tracer gases). Lastly, an improvement of the inclusion of the bluiding thermal dynamics during the test will be proposed in the last chapter. The basis of this improvement is to adapt the inverse model according to the building type and the test conditions. To do so, the proposed algorithm selects a model form a variety of simplified greybox models based on statistical criteria and parcimony. All these contributions have been tested on a large serie of measurements on a same timber-framed building (OPTIMOB shed). The robustness and precision of the results have been slightly improved. The intial infiltration air flow calculation, neither too simple of too complicated, has also been validated. Finaly, a better ordrer of magnitude of the minimal test duration has been determined, depending on the building inertia
