This evaluation is based on WELL v2 tool. The energy performance assessment is achieved by Design Builder software which allows creating the reference point building (building complying with ASHRAE 90.1 standards). The results show that energy consumption of the studied building is 220.75 kWh/m2. While for the reference building, the energy consumption is estimated to 277.7 kWh/m2. Therefore, the achieved savings of 20.5% consents attainment of a relevant score of 9 points according to the LEED v4 reference. The environmental impacts are evaluated using the attributional Life Cycle Analysis (LCA) approach by means of: OneClick LCA software, ecoinvent, GaBi database and the CML method. The Carbon footprint of the baseline construction showing results is numerically higher with an estimated value of 58.79 kg CO2e/m2/year while the proposed building was estimated at 15.58 kg CO2e /m2/year. according to the results of the analysis of the building's life cycle impact, the energy consumption can greatly increase ADP-Fossil results that achieve a score of 3 points according to the MR Credit 3 of LEED v4 tool. In addition, according to WELL v2, we note that the notion of sustainability is strongly present at the level of the educational building in Ifrane. In this scope, the building is obtaining a score of 1 point for concept L03, 1 point for L08, 3 points for V03, 2 points for V06, 2 points for V08 and 2 points for M09.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115809517","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}

Their capacity is typically 2–3 times higher than that of the graphite/carbon-based electrode materials. Moreover, their low cost and environmental benignity render them promising anodes for the next-generation lithium-ion batteries (LIBs). In this work, we report the synthesis of Ni<inf>0.5</inf>Mg<inf>0.5</inf>Fe<inf>1.7</inf>Mn<inf>0.3</inf>O<inf>4</inf> anode material by a sol-gel method. The synthesized product was characterized by X-Rays diffraction (XRD) and Raman spectroscopy techniques. The XRD result showed that at 800 °C temperature, the material exhibits a cubic symmetry with the space group (Fd-3m). The Raman's spectroscopy results showed that there are six Raman active modes (A<inf>1g</inf> (1), A<inf>1g</inf> (2), T<inf>2g</inf> (1), T<inf>2g</inf> (2), E<inf>g</inf> and T<inf>2g</inf> (3)), which are all observed at 800 °C temperature. The electrochemical properties of this anode material are investigated by galvanostatic and cyclic voltammetry tests. The material delivers an initial discharge/charge specific capacity of 1275 and 874 mAh g−1 under the current density of 100 mA g-1.

Two MPPT techniques have been presented which are SDM-BSC and ANNDDM-BSC. In the SDM-BSC control, the reference voltage that guarantees the maximum power point is generated by an analytical equation. The nonlinear backstepping control was introduced to track the reference voltage generated with the single diode modeling (SDM) by adjusting the duty cycle of a SEPIC converter. In order to improve the maximum power point tracking performance, the (SMD) is replaced by an artificial neural network (ANN) trained by a PV modeling based on DDM. The ANN is trained using double diode modeling (DDM), by varying the temperature and irradiance and computing the maximum voltage in every condition, thus a database of about ten photovoltaic module operating scenarios has been developed, which includes the temperature, irradiance and the maximum voltage delivered under every operating conditions. The ANN was designed with two inputs, which are temperature and insolation, and with a single output, which is the optimum voltage. The simulation results in the Matlab software showed excellent stability and speed compared to the InC-BSC and PO-BSC methods. And a power gain of about 0.3 W compared to the MSD-BSC method. The experimental setup has shown that the two proposed methods can be easily implemented and confirms the superiority of the ANNDD-BSC method.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117104766","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}
