Conservation Of Heritage Building Facade, The Case Study Of Traditional Tower Houses In Old Sana’a, Yemen
(2024-09)
Abdulhameed, Noran Abduljabbar Mohammed
Old Sana'a's traditional tower houses, a UNESCO World Heritage Site, face ongoing threats from unregulated alterations and modern construction practices. These changes have compromised the buildings' authenticity and cultural significance, highlighting the need for a comprehensive approach to heritage conservation. This study investigates the relationship between authenticity and conservation interventions in the context of tower house façade preservation. Employing a qualitative methodology, this research delves into three case studies of tower houses that have undergone recent alterations, supplemented by interviews with heritage conservation experts. Fundamental authentic values embedded in the façades, such as material choices, design elements, and their relationship to the urban fabric, are identified and analysed. The study examines the extent to which conservation interventions have impacted these authentic values and evaluates their effectiveness in preserving the cultural heritage of Old Sana'a. Challenges such as the absence of clear guidelines, limited institutional capacity, and a lack of public awareness are underscored. Based on these findings, the research proposes a comprehensive conservation guideline that prioritises the preservation of authenticity. This guideline emphasises using traditional materials and techniques, carefully assessing proposed interventions, and robust community engagement. These recommendations aim to inform policy development, guide conservation practice, and raise public awareness, ultimately contributing to the long-term safeguarding of Old Sana'a's unique architectural heritage.
Destination Choice Through Push And Pull Motivations Factors Of Vietnamese Domestic Tourists
(2024-04)
Nhu Ngoc, Ho
This study investigates the destination choices of Vietnamese domestic tourists through the lens of push and pull motivational factors. The objectives are to identify the underlying travel motivations perceived by Vietnamese domestic tourists, examine the push and pull motivational factors, and compare the important of push and pull motivational factors on destination choices across destinations. A quantitative approach was employed. Descriptive analysis, factor analysis, and binary logistic regression models were applied. The findings resulted from descriptive analysis revealed the six push motivational items that pushed Vietnamese domestic tourists and five pull motivational items that pulled them to specific destinations. Additionally, the study identified seven push and four pull motivational factors from the findings resulted from factor analysis. Based on the results from binary logistic regression it found that while push motivational dimensions did not differ significantly across destinations, pull motivations dimensions varied. Various pull dimensions influenced the choice of different destinations. The study contributes to both practical implications and academic literature. Academically, it enriches the understanding of tourist behaviour and destination choice, particularly in the context of Vietnam, and provides a framework for future research in tourism studies. Practically, it offers insights for tourism stakeholders to tailor marketing strategies and develop tourism policies that align with the motivations of Vietnamese domestic tourists. Several implications based the findings of this study provided tourism authorities to create tourism policies.
Effectiveness Of Semi-Transparent Photovoltaic Application At Highrise Vertical Facade In Malaysian Urban Area
(2024-08)
Mahmoud Rababah, Haitham Esam
This research endeavours to leverage the vertical facades of buildings within Malaysia's high-rise urban areas to generate renewable energy, addressing the challenge of limited space for traditional solar installations. Specifically focusing on the urban setting of Kuala Lumpur, the study employs sophisticated modelling and simulation techniques to assess solar exposure potential and optimise the placement of photovoltaic (PV) panels. The primary objective is to explore the feasibility and effectiveness of utilising vertical surfaces for solar energy production, by concentrating on a specific area encompassing high-rise buildings in Kuala Lumpur. By using Revit software for developing a conceptual 3D model and IES VE software for simulations, the study focused on factors such as neighbouring buildings, shading effects, and distances to ascertain their impact on solar exposure. The findings highlighted that installing PV panels have the potential to reduce electricity costs by 42.67%. Moreover, the research underscores the economic viability of this approach, with an estimation that PV panels have an average Return on Investment (ROI) between 6.7% and 11%, depending on the ratio of PV panels to windows, this innovative integration promises significant returns for building owners. Overall, the research signifies a promising step towards sustainable urban development, demonstrating the potential of vertical facades in contributing to renewable energy goals while enhancing the urban landscape.
Impact Of Building Envelope Modifications On Thermal Performance Of Classrooms In Typical Schools In Hot Arid Climate Of Oman
(2014-04)
Ali, Alsaadi Mutaib Ibrahim
This study addresses a critical oversight in environmental design and energy conservation for typical government schools in Muscat, Oman, which grapples with inadequate adaptation to its hot-arid climate, leading to a heavy reliance on mechanical systems for temperature control. This research examined the thermal performance of building envelope elements and their impact on indoor air temperature by modifying the exterior wall, roof, glazing type, window area, and orientation. Simultaneously, it provided nuanced design recommendations for optimal thermal comfort. The study was conducted in two pivotal phases. The first phase involved fieldwork measurements in three secondary schools, providing a real-world snapshot of existing thermal conditions within such buildings. The second phase employed computer simulations using Design-Builder software to replicate field measurements, explore hypothetical scenarios and modify building envelope elements. Winter indoor temperatures recorded in the fieldwork phase ranged from 24.2oC to 24.8oC, ensuring a baseline understanding of the existing conditions. In contrast, summer temperatures spanned from 32.7oC to 33.3oC, illustrating the considerable temperature fluctuations of typical schools. The recorded field measurements and the simulation results revealed a close alignment of minimal differences of less than 2oC, highlighting the study's credibility and strengthening the validity of the proposed design recommendations.
Business Environment Uncertainty`S Effect On The Performance Of Three Stars Hotels And Below In Saudi Arabia: The Mediating Role Of Competitive Advantage
(2024-07)
Ali M, Alsubaihi Ibrahim
Despite the rising demand and occupancy rates in Saudi Arabia's hotel industry, the sector faces significant performance challenges due to intensified competition and supply dynamics. The proliferation of small and medium-sized accommodations has compelled hotel managers and owners to adopt competitive strategies to navigate environmental uncertainties successfully. This is particularly crucial in today's global context, where uncertainties have become prevalent across various domains of life, including the hospitality sector. This study examines the relationship between environmental uncertainty and hotel performance within the context of small and medium-sized hotels in Saudi Arabia, focusing on how competitive advantage acts as a mediator in this relationship. The study encompassed five major regions in Saudi Arabia: Mecca, Medina, Riyadh, the Eastern border, and Jazan. Employing a quantitative approach, the instrument of survey form was used to targeted group of top management personnel and accommodation owners with a sample size of 375 respondents. Data was collected through an online questionnaire survey distributed via email to identified hotels. The study garnered a substantial response, with 238 usable responses. The data was meticulously analysed using statistical tools such as SPSS and SmartPLS 3.2.1. The study's key findings unveiled a strong and significant relationship between market uncertainty, technology uncertainty, competitive uncertainty, competitive advantage, and hotel performance.
