The aim of this research is to optimize a methodology used in eco-design, that so-called Life Cycle Assessment (LCA), in order to increase its representativeness when evaluating systems. This optimization consists of introducing temporal factors in the environmental impact assessment. This process is called Dynamic Life Cycle Assessment (DLCA). It uses the Enhanced Structural Path Analysis (ESPA) method combined with OpenLCA software and an algorithm written under MATLAB. Then, the Life Cycle of the Inventory (LCI), carrying out the inventory of input and output masses of the controlled compounds (NOx, O3, PM10, etc.) for relevant studied subsystems, takes the date of the process into account and breaks the amount of pollutants flows down. A double glazing bay was chosen to apply this method.

The composite Cobalt hydroxide/ternary nitrogen, phosphorus and sulfur doped graphene (Co(OH)2/NSPGr) as catalyst for oxygen reduction reaction (ORR), was synthesized by hydrothermal method. The catalytic activity for ORR of catalyst samples were studied by rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) in alkaline medium. Compared to Co(OH)2 which shows a poor catalytic activity, Co(OH)2/NSPGr composite exhibits better catalytic performances, including more positive onset potential and higher limiting current density. Moreover, RRDE results indicate that the composite undergoes a 4-electron electrochemical process as well as a low production of hydrogen peroxide % H2O2. The enhanced performances of Co(OH)2/NSPGr composite could be attributed to the effect of heteroatom doping of graphene and also the strong chemical coupling between Co(OH)2 and NSPGr.

Energy demand within the residential sector represents a fairly large percentage at 25.4%, which exceeds 1/4 of the total energy consumption. In this regard, decreasing this consumption is to be preferred in order to align with the Moroccan strategy for energy efficiency. Houses, which have low consumption, can be very auspicious. The goal of this project is to design two types of small low-energy two-storey houses with an area of 35m2 each, taking into consideration the weather and the climatic characteristics of Ben Guerir city and later compare the results with respect to a conventional one. First of all, we will present an overview of the passive strategies of the building's energy. Then, this data will be used to propose two configurations of energy efficient homes. Furthermore, we will carry out the thermal study of these two houses along with a standard one. Our goal is to undergo a thermal analysis of three residential buildings with a Dynamic Thermal Simulation software DESIGN BUILDER. We’ve found that the conventional house doesn’t respect the requirements underlined by the the Thermal Regulation for Construction in Morocco (RTCM). However, the two other proposed conceptions abide by the regulations. This comparative study showcases that accurate building materials combined with passive strategies with respect to local climatic conditions can help reduce significantly thermal loads inside the houses.

Medium Access Control (MAC) protocol plays vital role for improving the efficiency of wireless sensor networks (WSNs). Thus, several energy efficient MAC protocols are introduced for better outcomes. This paper introduces an energy efficient Medium Access Control (EE-MAC) protocol for WSNs. EE-MAC handles idle listening and congestion problem to preserve the energy. EE-MAC uses semi synchronous low duty cycle that takes less time for channel access. As a result, higher data delivery rate is expected, and extra energy is preserved. Evaluation of EE-MAC is performed using network simulator-3 (ns3) then compared with X-MAC (low duty cycles energy efficient protocol) and low power listening (LPL). We compared BN-MAC with MAC hybrid protocols: Speck-MAC, Boarder Node MAC (BN-MAC), advertisement-based MAC (A-MAC), Adaptive Duty Cycle SMAC (ADC-SMAC) and low power real-time MAC (LPR-MAC) protocol. Based on initial experimental results, we demonstrate that EE-MAC protocol saves additional 2% to 4.5% energy as compared with other MAC protocols.

Small faults, cracks, and other structural defects that occur in some components of a wind turbine, might lead to a catastrophic failure. Moreover, an important operating requirement that relates to a wind turbines airfoils are its ability to perform when the smoothness of its surface is compromised. The accreted dust on the surface of blade increases the drag of the airfoil and a decrease in the lift, while large accumulation can lead to complete turbine stops, thereby reduction in the power output of the wind turbine. Additional, to accreted dust and debris. To prevent such failures, proactive measures have to be taken to identify and detect defects at its early stages. In this paper, vibration signature of the structure is utilized for identification and detection of defects. Changes in resonant frequencies and resonant amplitude of the turbine blades are compared before and after damage. These changes are utilized as means for identifying damage in the blades. A 2k factorial experiment is constructed to generate changes in resonant frequencies and spectral amplitudes due to changes in crack length, location from the center of the blades’ hub, and the orientation of the crack. Three accelerometers placed at the hub center, middle and tip of the blade measure the acceleration at corresponding locations. Power spectral density (PSD) of acceleration is generated for various test conditions in the factorial experiment. Damage in the vicinity of the accelerometers locations have well defined power spectral densities. However damage characteristics at all other locations are predicted using the Kriging method in which, given measurements at a set of locations in a region, Kriging creates a map of predicted value throughout the region. Damage characteristics estimates using the proposed method revealed an error as low as 0.3%. Simulation is used to validate the proposed method and the results are discussed.

This paper is about evaluating the energy potential of the roof of a typical modest village house of 77m2 in Zaouiat Sidi-Abdeslam village and compute its approximate electrical energy generation per year potential, on while taking into account different variables that might affect the end photovoltaic system output, for instance shading scene, wiring losses, system losses etc. using PVSYST software. The simulation resulted in a total of 9666 kWh/year produced by a conventional polycrystalline photovoltaic panels system. The photovoltaic roofing technology was also evaluated, especially TESLA’s innovative technology of solar shingles. A solar tile has been made using tempered glass as the encapsulating material, and the process of material selection is made clear as the project unfolds. After the prototype has been developed and assembled, it was subject to different tests. The Mechanical test using a load calculator has showed that the maximum load capacity that the tile can stand is 543.3 kg. The electrical test of the photovoltaic tile resulted in a measured efficiency of 9.75% while the theoretical one can reach up to 15.63%. While the thermal test revealed that the tile can heat up to 30°C in a day in which the ambient temperature does not exceed 16°C.

In this paper, an efficient and fast MPPT power control of photovoltaic systems based on backstepping approach is presented. The proposed control scheme consists of two cascade loops; in the first loop, the auto-scaling variable step-size perturb and observe MPPT technique estimates the reference voltage of all electrical load values. The robust backstepping controller has been adopted to remove steady state oscillations in the second loop. Further, the performance of proposed control system has been analyzed through dSPACE DS-1104 experimental validation with Isofoton photovoltaic module under real climatic conditions at Biskra (Algeria) region. The results obtained by the used controller averred a good improvement.

within the framework of the sustainable development, the building sector seems an important component of the green economy programs in Morocco. Major research studies are undergoing in this field in order to highlight passive low-energy consumption construction techniques. And especially in Morocco, Energy efficiency in buildings is a national priority. Given the advantages of indigenous materials, academic institutions and industrials alike try to promote the development of new materials, especially the hygrothermal performance improvement of green building materials, that improve internal thermal comfort. Following this trend, hemp material is a good choice to respond to this demand and it is more and more used in construction. This paper comes in this order of ideas. And it aims to study and evaluate the thermal performance of hemp building envelope compared with two conventional construction alternatives. The building design of three case studies are based on the recommendations of Givoni and Mahoney methods. So as to compare between the performances of the three variants, we carried out a thermal simulation of the thermal behavior of each one by the dynamic thermal simulation software software DESIGN BUILDER considering a typical meteorological year (TMY) of Tangier, which refers to the second climatic zone in the thermal regulation for constructions in Morocco (RTCM).

And it aims to study and evaluate the thermal performance of hemp building envelope compared with two conventional construction alternatives. The building design of three case studies are based on the recommendations of Givoni and Mahoney methods. So as to compare between the performances of the three variants, we carried out a thermal simulation of the thermal behavior of each one by the dynamic thermal simulation software software DESIGN BUILDER considering a typical meteorological year (TMY) of Tangier, which refers to the second climatic zone in the thermal regulation for constructions in Morocco (RTCM).","PeriodicalId":186042,"journal":{"name":"2018 6th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128007528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
