Solar chimneys play a major role in improving thermal comfort for university spaces. The research dealt with the design of eight Solar chimneys on the southern facade of a classroom in the university campus in Sohag, Arab Republic of Egypt, to achieve the maximum indoor air velocity and the lowest temperature during the summer, with a special focus on thermal comfort for students, as the ANSYS program was used to simulate and analyse air movement, fluid flow, temperature distribution, and electromagnetic efficiency, and the study of other effects over time. A 3D model of the hall was created using Solid Work, and a solar chimney was proposed using PCM panels to achieve the best passive ventilation. First, the CFD numerical analyses were performed within the ANSYS program to test the best solar chimney dimensions and compare the results with field measurements. (DOE) experiments were conducted on two fixed dimensions with chimney widths 20 cm and 40 cm, with testing the chimney entrance openings of 20 cm x 20 cm and 40 cm x 40 cm and testing the internal temperature and air velocity in the hall over the study months in summer and winter and understanding the mechanism. The physical phenomenon of atmospheric buoyancy. The experiments also included the design of a solar chimney with a 45-degree inclined roof attached to a runway without considering the humidity factor. for the effect of wind speed in a vacuum with a deviation (RMS) of 0.8% between the two values. Runway temperatures were reduced by 2.5°C by","PeriodicalId":440630,"journal":{"name":"MSA Engineering Journal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116948052","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}

Architectural thinking usually uses a standard space prototype, giving no respect for students` learning styles. The scope has covered a deductive framework within a survey that started with a learning styles questionnaire and ended with an applicable descriptive study with a sample of architectural students to frame their environmental preferences according to their learning style. The methodology utilized multiple data accumulations as questionnaires, interviewing participants individually and noting their descriptions of their favorite inspiring spaces. Afterward, the data investigation was designated using Statistical Analysis Software (SAS) for data analysis and the Midjourney AI server in the text-to-image generation stage. The initial results showed how much architectural students prefer the reflector learning style. Although participants are different in gender and locality distribution, most showed a clear tendency to the inspiring personal space. Remarkably, the intermission space showed a higher preference frequency than the presentation space, which reflects the self-motivated nature of inspiration. In contrast, all participants showed little interest in inspiring collaboration or making spaces. Consequently, the analysis concluded a descriptive study minding the characteristics of different categories of personal spaces described by architectural","PeriodicalId":440630,"journal":{"name":"MSA Engineering Journal","volume":"106 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126232019","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}
