In a bid to mitigate energy consumption and achieve thermal comfort, several countermeasures have been suggested. Green and thermally insulated roofs are presented in this paper. Experimental research and numerical simulation analysis applied to a school building in Gaza Strip. This research is the first of its kind in this geographical area. The experiment using design builder 6.1.0.006 software is conducted to compare four types of roofs (a traditional roof, a traditional roof with thermal insulation, a green roof, and a green roof with thermal insulation) during all seasons of the year (hot-humid summer, cool winter, and equinoxes). The research aimed to determine which of the roofs would give more thermal comfort. Essential parameters of green roofs, such as leaf area index (LAI) and soil depth, are also set at different values to determine their effects. It is found that the thermal performance of green roof with thermal insulation is the best throughout the year, as it offers the best PMV values. In addition, higher LAI is the key to maximize energy savings in hot humid season but it increases energy consumption in cold seasons, and higher soil depth is the solution to reduce energy consumption in the cold season, but it has a negative effect in hot and warm seasons.","PeriodicalId":431920,"journal":{"name":"2023 8th International Engineering Conference on Renewable Energy & Sustainability (ieCRES)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125252715","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}

Furthermore, the increase in the poverty level among the people and the lack of fossil fuel resources, and the high intensity of solar radiation in the strip have grabbed the attention of the authors to think about a suitable alternative to produce potable water via solar energy. This study aims to investigate the linear Fresnel collector (LFC) coupled with a solar still-single effect active system. The solar still was designed to match the LFC output to avoid any heat losses that may decrease the system’s effectiveness. A CFD simulation was carried out using Ansys Fluent software to predict temperature and pressure distributions to find out the efficiency of the LFC collector. The results showed that the use of LFC leads to an increase in the efficiency of the solar still, and the daily production of distilled water reaches 1.5 $mathrm{Litre}/mathrm{m}^{2}$.","PeriodicalId":431920,"journal":{"name":"2023 8th International Engineering Conference on Renewable Energy & Sustainability (ieCRES)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128467632","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}

The results presented in this research is based on real measured data that had been collected over long periods of time series by monitoring and control systems of the considered power plants. Thus, the presented here Co2 emission factors on different basis can be considered as an indicator to the environmental situation of the power industry sector of Libyan State. The methodology used in this study can be adopted to estimate other air pollutions emission factors in the power sector or even in other sectors. The results were also compared with emission inventories published by environmental agencies such as IPCC, EAA, EAI, and EEM, as well as the standards set by UNFCCC.

The focus of this work is on investigating the effect of adding CdS quantum dots doped with Ag nanoparticles layer into the solar cell structure.

The proposed solar cell structure comprises $mathrm{F}mathrm{T}mathrm{O}/mathrm{T}mathrm{i}mathrm{O}_{2}/mathrm{A}mathrm{g}$-doped $mathrm{C}mathrm{d}mathrm{S}$ quantum dots/Iodide-Triiodide $(mathrm{I}^{-}/mathrm{I}^{-3})/$Platinum. The transmittance, reflectance and absorbance power are analytically studied using transverse matrix method and numerically calculated using Maple. The transmittance, reflectance and absorbance power is studied for different fractions of Ag nanoparticle and different CdSe quantum dots concentrations. Results show that the absorbance power increases as the fraction of Ag nanoparticles increases. In particular, there is a clear peak around 700 nm. However, absorbance hardly changes as quantum dots fraction changes.
