In hot arid environments like Egypt, adequate outdoor ventilation is required to aid in the removal of heat and pollutants and provide healthy living environments. In this context, the current research analyses the urban ventilation of typical Egyptian housing layouts using a simulated multi-directional approach. It is significant because few studies on evaluating urban ventilation of housing prototypes were undertaken in Egypt, and the approaches used were employed in nearly no relevant research in the region. Linear parallel, clustered, dot, and clustered-shifted patterns were investigated. Eight wind directions were analyzed to assess five parameters: 1) wind velocity, 2) age of air (aoa), 3) airflow, 4) pressure coefficient (cp) and 5) comfort index. An automated toolkit that enables the simultaneous simulation of several wind directions was employed. It consists of Eddy3D, a validated Grasshopper tool that uses OpenFOAM’s RANS models. The results showed that best velocities were found in the linear-parallel-unaligned and clustered layouts, directions NNE and N. The latter exhibited favorable airflow within its courtyards. In addition, wind directions had little influence on aoa, as did the layout pattern. Uncomfortable wind was greater in the clustered layout and lowest in the clustered-shifted layout. Except for ENE direction, cp was in opposition with ventilation, since W and WNW directions witnessed the greatest cross-ventilation potential. While linear-parallel-unaligned and clustered layouts created optimum ventilation and allowed outdoor activities, they require more research to increase cp and reduce uncomfortable winds.","PeriodicalId":31454,"journal":{"name":"HBRC Journal","volume":"14 4","pages":"453 - 481"},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138587754","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}

Since residential buildings are considered the main electricity consumer sector in Egypt, they consume up to 42% of total energy consumption, which contributes to increasing temperatures and constitutes UHI in cities. In this context, the research aims to examine the effectiveness of using the closed vertical loop geothermal system (GSHPCV) for cooling residential buildings in a hot, dry climate, such as Cairo, Egypt. In addition to determining its effect on carbon emissions and the amount of energy consumed for cooling, this was done using TRNSYS-17 software as a simulation tool to compare the traditional building in a hot, dry climate before and after adding GSHPCV in Cairo, Egypt. The simulation revealed that using GSHPCV in hot, dry climate zones has a significant impact on residential buildings. It reduced the electricity consumption up to 19.7% of the electricity consumed for cooling, and it reduced temperatures indoors for buildings up to 15.8% on the ground floor, up to 11.3% on the first floor, and up to 3.5% on the roof floor. In addition, it reduced up to 19.7% of the carbon emissions and reached human thermal comfort on the ground floor for the study case at peak times during the summer period. Which provide a solution to reduce UHI and environmental hazards such as climate change.","PeriodicalId":31454,"journal":{"name":"HBRC Journal","volume":"59 42","pages":"483 - 507"},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138592538","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}

However, the emergence of gated communities in Egypt has shifted priorities, prioritizing isolation over social interaction. This paper examines the impact of social interaction in gated communities in the West of the Greater Cairo Region from a social sustainability perspective. This study conducted a literature review on definitions and concepts of social sustainability and social interaction. We launched an online survey to measure social interaction in our case studies. We analyzed data retrieved from the survey to assess the correlation between social interaction and sustainability indicators. The results demonstrate that social interaction neutrally affects social sustainability indicators and users’ satisfaction. The survey findings indicate that users of gated communities rarely consider social interaction, which reflects their satisfaction with the isolation in the gated communities. As such, residents of gated communities should reconsider the shared spaces within these communities to improve social interaction and enhance social sustainability. This could lead to improved quality of life for people living in gated communities. Furthermore, improved social interaction within gated communities could also help to reduce social isolation and loneliness, which are associated with a range of physical and mental health issues.","PeriodicalId":31454,"journal":{"name":"HBRC Journal","volume":"51 5","pages":"543 - 562"},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138597439","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}

Recent studies have focused on the relationship between spatial characteristics and wellbeing, and the relationship between transportation and mobility with subjective wellbeing of the people. However, few studies tackled the influence of the urban form and the elements of built environment on wellbeing during commuting in the city. This manuscript discusses the concept of urban form, and perceptual qualities of urban design. Afterwards, it proceeds with delineating the research variables (i.e., Spatial and Perceptual). The case study selected is South 90 Street, New Cairo, Egypt, which serves as an urban corridor that accommodates various transit modes, diverse land uses, and variety of urban facades. The analysis is carried out utilizing the built environment dataset and collected responses about users’ experience via a questionnaire. This manuscript attempts to answer two main questions: (1) What is the influence of urban form on commuters’ travel time perception? (2) How do the elements of the built environment impact the subjective wellbeing of commuters? Descriptive analysis is conducted to understand the relationship and influence of the built environment on the perceived travel time during mobility and individuals’ wellbeing. The manuscript further discusses the results, depicting which built environment elements are associated with either positive or negative effect on commuters’ subjective wellbeing. The manuscript concludes with highlighting the potentials for maintaining the overall wellbeing of individuals and their perception during urban mobility. Thus, facilitating the design of functional, efficient, and reliable cities.","PeriodicalId":31454,"journal":{"name":"HBRC Journal","volume":"11 10","pages":"563 - 587"},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138594522","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}

One of the most important buildings of Iran from the Zandiyeh Era (250 years ago) is Vakil Mosque, which is located in Shiraz. Vakil Mosque is a sacred and Islamic building in Iran, which is the aim of this article to investigate and find geometry in the architectural body of this building. In the current research, descriptive-analytical methods were used to collect data. Then I studied the geometrical drawings of this mosque, which some of the most important books of Muslim scholars in this field have been studied to obtain the geometry of the plan and elevations of Vakil Mosque, and after many tests and finding acceptable answers, options were proposed as the physical geometry of this sacred building. Finally, I came to the conclusion that the architect or architects of this magnificent building have used their utmost efforts in designing its physical to create golden proportions and regular geometry on it, and this order and geometry is the reason for the glory and strength of this building. The findings of this article can be used along with other similar studies to recognize Iran’s architectural works and restore its original Islamic-Iranian identity.","PeriodicalId":31454,"journal":{"name":"HBRC Journal","volume":" 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135286550","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 research is focusing on the idea of heritage preservation from a different perspective, adopting branding techniques and mechanisms to overlap the two disciplines in a study framework. Branding heritage re-introduces heritage values from the marketing perspective, in which the research reflects the idea of the place attachment and refreshes memories from the economic dimension. The research proposes a structural framework that accommodates the literature domains of heritage preservation as tangible elements, patterns, geometry … etc. and intangible values as spiritual, sense of place … etc. mapped with the branding approaches. The aim of this research is to trace the branding heritage tactics and examine the approach. The purpose is to preserve heritage from deterioration and use its values as economic assets. The research intends to validate the importance of marketing experience in branding heritage process, using the symbols of tangible and intangible meanings and its significance. The research anticipates studying marketing the heritage within multi-cultural societies, in terms of contributing the heritage of some urban setting within the heritage of others. The proposed structural framework reflects the mechanism of branding heritage.
