ARCHITECTURAL REPRESENTATIONS OF HUMAN RIGHTS
The United Nations defines the Human Rights as the rights of all human beings, regardless of race, gender, language, religion, nationality, or any other status. These rights include all claims to live freely, to educate and work in equality, and to inhabit humanistic urban and architectural spaces. Throughout the history of architecture, civilisations have generated different perspectives towards respecting the human rights. Temples of Ancient Egyptian Architecture crushed the human scale to introduce religious experiences to their visitors. Tibetan temples over mountains enforced people to make anti-humanistic journeys to reach them. After thousands of years, the mega-scale palaces and cathedrals in the Gothic era underestimated the human scale due to the powerful rule of Church in Europe. On contrary, pioneers of Renaissance Era made an intellectual revolution to respect humanism through humane proportions. After a while, the Industrial Revolution employed all materials, machines, and sciences to serve humanism. Architectural projects therefore fulfilled the physical without covering the spiritual and emotional human needs. This remained until 1960s when the postmodern architecture emerged. Nowadays, several architectural projects have unfortunately neglected achieving equality for all categories of users. Critics, such as Jane Jacobs 2000, have pointed out that a number of starchitects - pioneers of the architectural world - have designed anti-humanistic spaces. Within the onslaught of digitization, deconstruction, and free forms, some architects have celebrated the power of building technology in designing non-traditional compositions, disregarding the humane essence. These uncanny forms have missed the feeling of humane dimension. This research aims to investigate the relationship between architecture and human rights, trying to propose a new architectural manifestation putting the human rights as the first priority. In order to achieve this aim, the paper followed scientific methods, starting by literature review defining the meaning of human rights, its values, and its relation to the humane architecture. To collect this data, the authors depended on desk research and reviewed previous readings to highlight the examples that put the humane factor at the first place as the main design-concept. A deep analysis for two case studies has been conducted, based on observations, photos, and documentation. Authors experienced these two projects during personal site visits. The analysis detected the architectural representations of humane design in both projects. A comparison between the case studies presented the most important elements and features that their architects were keen to apply. The research concludes that architecture and human rights are inseparable, and the design of human space needs a symphony of multiple tasks and elements including specific materials, meaningful spaces, and advanced technology
EVALUATING THE TRANSFORMATION OF LAND USE AND MORPHOLOGY ON THE MICROCLIMATE: THE CASE OF GEMMAYZEH NEIGHBOURHOOD – BEIRUT
This paper investigates the effect of urban areas on local climate by examining the correlation between urban morphology, land use and urban thermal climates. It focuses on Gemmayzeh area in Beirut. Urban parameters were evaluated by developing an energy balance model with the aim of understanding how heterogeneous geometry, height, and finishing material can change the mechanical and thermal structure of the urban atmosphere. It simulates the current urban condition in order to compare it with other scenarios using ENVI-met 4.The results from the numerical simulation reveal that a network of green infrastructure connecting the existing green patches can ameliorate heat extraction and improve the outdoor thermal comfort level. The PMV value at the pedestrian level is reduced from extreme heat stress to moderate heat stress near the green areas. The study concludes that Beirut city center can mitigate the urban heat island by using vegetation and especially green roofs and densification of high trees in the left over spaces
Optimising the urban environment through holistic Microclimate Modelling – The case of Beirut's pericenter
Various studies have suggested that urbanisation may significantly alter microclimate conditions. To address this, expanding urban vegetation cover can be used to aid the dissipation of excess heat through enhancing evapotranspiration. This study aims to numerically assess and optimize the use of green corridors to reconnect leftover and in-between building plots within Beirut city centre through the use of ENVI-met V4, a holistic microclimate modelling system used to optimize green
infrastructure strategy to improve pedestrian comfort
levels. Analysis results illustrate the significant effect of urban intervention strategies in decreasing pedestrian
heat stress, where the air temperature is reduced by 4-5 (PET) °C. Furthermore, a correlation between the leaf area density and PET values was identified. In the wider context, this work supports the case for the application of ecological urbanism supported by integrated micro-urban environment modelling as a catalyst for the improvement of the quality of urban space
THE IMPACT OF INDOOR ENVIRONMENT QUALITY ON THECONSERVATION PRACTICE OF HISTORICAL BUILDINGTHECASE OF LEBANESE COASTAL ZONE
It is widely acknowledged that a multidisciplinary approach should be adopted to conserve historical buildings that include indoor environmental features. This paper discusses the effect of healthier indoor environment requirements on the conservation of historical buildings. Conservation, being an essential sustainable practice using inherited built assets to satisfy present needs, imposes limitations on the intervention that can be induced to historical buildings. Healthier indoor environment requires controlling various factors as Indoor Air Quality and Thermal Comfort, which directly affect the Heat-Air- Moisture transfer (hygrothermal behavior) of the historic building envelope and may lead to its deterioration and degradation. Focusing on the historic built fabric of the Lebanese coastal zone, this paper investigates the impact of Indoor climate control on the pathology of the historic building envelope and presents recommendations that mitigate that impact while preserving both conservation requirements and occupant comfort. A case study analysis is conducted to identify the qualitative parameters in the Indoor space of an 18th century heritage building located in the coastal zone of Lebanon and used as public building. The conclusion highlights the potential for comfort establishment in refurbished historic building through raising awareness in relation to occupant behavior and identifying scientific approaches to control hygrothermal behavior of the historic envelope, by the mean of whole building simulation software, which adds significant contribution to the conservation practice
Monitoring participatory approaches in Mediterranean waterfront developments (El Mina, Lebanon; Alexandria, Egypt; and Antalya, Turkey)
Public participation is an important tool for communities to influence development decisions for public spaces in general and waterfronts in particular. In coastal cities, waterfronts are an important touristic attraction and are affected by social and economic issues. Users’ activities and responsiveness to waterfront projects are affected by the development types and methods. This study is part of ongoing research aiming to evaluate the participatory approach methods in the waterfronts of Mediterranean cities. It examines three coastal cities that have developed differently based on sustainable development studies. This study is a top–down approach that investigates the applied phases and methods of participation and evaluates these involvements after comparison with the preferred phases and methods. This paper uses qualitative and quantitative methods, which are based on analysis of social studies about participation priorities. It uses methods such as documentation, lengthy interviews and questionnaires with visitors. The outcome of this research proves the need for application of participatory approaches in Mediterranean cities
INVESTIGATING COMMERCIAL URBAN CORRIDORS - A PILOT STUDY IN BEIRUT LEBANON
Urban environments are multifaceted, varied, dynamic, complex, and evolving as are the underlying features for human health and wellbeing (Bai, Nath, Capon, Hasan & Jaron, 2020). Healthy and resilient cities can be entry points and platforms for change, adaptation and innovation to achieve optimal health for urban communities and the environment (Regional Framework for Urban Health in the Western Pacific 2016–2020: Healthy and Resilient Cities, 2016). Planners considered urban corridors, which are connection and access between urban districts, as major elements in shaping the city image and forming its identity and investigating them are vital for enhancing healthy and resilient cities. Narrowing the scope on commercial urban corridors, which are a concentration of retail stores that serve a common trade area and lie along a single street (Catherine Dyste, 2012). These corridors can be seen as a dynamic space, but at the same time, they are created to create a range of experiences (Shaban et al., 2018). Improving commercial urban corridors requires several indicators for reviving the companionable and sociable life of a street. Problems occur when space use is not driven. The society therefore uses the urban commercial corridor according to their own interests. This condition may generate conflict between users of the \u27Link\u27 and users of the \u27Space’, may make the corridor an uncomfortable location, and may decreases its livability. Rapid urbanization and unplanned rapid changes of commercial activities in corridors that have an impact on the surrounding streets and users’ activities imposes burdens on surrounding land use and mobility. However, this problem has contributed to various issues such as traffic congestion, pollution, decrease in green areas and degradation of the urban quality of living. That’s why investigating these corridors is imperative to know its utilization and functioning to identify the existing problems and chaos in the corridor since they are facing significant challenges, which is the lack of reliable knowledge on their characteristics and development; important for local authorities to provide wealth of knowledge and data collection. The paper aims to investigate commercial urban corridors to identify and analyze livability aspects and indicators for reviving its companionable and sociable life that can be implemented in a way of a considerable checklist which acts as a systematic structure for communicating the data required, diagnosing issues, and defining the strengths and limitations of the efficiency of a commercial urban corridor to promote a healthy and resilient urban context. To achieve the aim, the research investigates a commercial urban corridor focusing on one of the urban corridors in Beirut, Lebanon. By using Geoportal Interactive Tool, conducted by UN-Habitat and UNICEF to create cartography of the existing conditions of the pilot study, and then analyzes the aspects and indicators of livability based on cartography, walk through analysis and face-to-face interviews with inhabitants in area. After analyzing the commercial urban corridor and identifying the effective indicators, the research resulted in proposing some guidelines for enhancing livability in commercial urban corridors, which were mainly related to the physical aspect since it defines the most inadequate quality and performance
THE IMPACT OF PLASTERING ON THE HYGROTHERMAL BEHAVIOUR OF HISTORICAL SANDSTONE LOCATED IN THE COASTAL REGION OF LEBANON
In an unusual trend in the conservation practice of built heritage in Lebanon, the external plaster layer, which protects the sandstone from weathering factors, is being removed for aesthetic reasons. These buildings are in a coastal region, hot humid climate in the summer and moderate cold weather in the winter. This paper discusses the importance of external and internal plastering of the historical sandstone bearing wall, by the mean of a computational tool that underlines the role of the plastering in the hygrothermal behaviour of the historical stone, in the aim to validate the practice of the ancestors in covering the envelope of their buildings to avoid the degradation of these natural stones. The methodology adopted in this paper is a comparative quantitative study, using a hygrothermal simulation modelling tool, named Wufi Pro, which is a standard program for evaluating moisture conditions in building envelopes developed by the Fraunhofer Institute for Building Physics (IBP) Stuttgart, Germany. The results are in the form of values for the heat and moisture fluxes through the high porosity sandstone assembly that composes the building envelope. These values represent the hygrothermal behaviour of the stone, and they are compared between two cases, one without plastering while the second has the inner and outer layers of traditional plaster. The analysis of the results is guiding to a conclusion that favours one of the two cases, taking into consideration the interstitial condensation threat avoided by the means of plastering
THE IMPACT OF CHANGES IN BEIRUT URBAN PATTERNS ON THE MICROCLIMATE: A REVIEW OF URBAN POLICY AND BUILDING REGULATIONS
Previous studies conducted on Beirut have historically overlooked research in the field of urban microclimate. A better understanding of how Beirut urban development, including zoning and building regulations, has affected the current urban thermal climate is crucial in order to analyse how different factors have led to the structure of the city, including the quality of urban space and the degradation of its natural environment. Within the context of limited government capability to set out strategies for sustainable urban development, this paper examines the historical evolution of the Lebanese building regulations specifically in Beirut and investigates the impact of changes in building regulations on the city’s urban microclimate. The review highlights the historical urban growth of the city and identifies the dynamics that have contributed to the uncontrolled expansion of the built up areas. Analyses linked to the direct effects of the urban morphological features forming a different local microclimate in Beirut. Initial findings highlight the correlations between building regulations and the different urban design factors and how they affect Beirut local climate, resulting in the formulation and adaption of the necessary strategies to alleviate unhealthy urban conditions
Conservation of Beirut’s Urban Heritage Values Through the Historic Urban Landscape Approach
Cities are complex urban systems with dynamic transformations in their socio-economic and environmental dimensions. Several studies have shed light on the fragility of the urban heritage and the strategies of its conservation. The historic urban landscape (HUL) approach is a new framework adopted by UNESCO to deal with urban heritage. This article aims to apply the HUL approach to the rehabilitation and management of Beirut historic neighbourhoods impacted by the massive Beirut port explosion, focusing on Armenia Street in the Mar Mikhael neighbourhood as a case study. The application of the HUL framework allows for the re-evaluation of heritage not as an individual physical form but as an urban fabric interconnected to the city, inclusive of its cultural, social, architectural, and urban layers. The article investigates the application of the four tools identified within HUL recommendations—(1) regulatory systems, (2) community engagement, (3) planning, and (4) financial tools—by proposing implementation strategies in the assessment of urban heritage to mitigate major risks. The result reveals that cooperative efforts among private and public stakeholders can play a vital role in the development of Beirut heritage, acting as catalysts for urban heritage conservation. Strategies for establishing a new legislative framework that is focused on protecting Lebanese cultural heritage and ensuring sustainable adaptation planning are highlighted
INVESTIGATING THE RELATIONSHIP BETWEEN USER\u27S DENSITIES AND FUNCTIONS DISTRIBUTION ON MEDITERRANEAN WATERFRONTS: STATISTICAL ANALYSIS APPROACH
The type of buildings and activities along the waterfronts have to stimulate the interactivity between public spaces and their users to reach the desired comfort, enjoyment and appropriate densities. This study is part of a continuing research and it aims to highlight the spatial relationship between the type of buildings and the densities on cities waterfronts of the Mediterranean Sea. It undertakes three case studies with different economic and touristic levels. It is a top-bottom approach that analyzes the existing population densities on waterfronts and the surrounding building functions. This paper uses quantitative analysis based on spatial statistics along each of the three waterfronts. The data collection is made through documentation, direct observations, mapping, Global Positioning System, and Geographic Information System software. The outcome of this research evaluates the relationship between functions and population densities to record how locations of functions increase population on waterfronts by making them attractive and recommends how waterfront zoning laws will consider specific land uses and techniques
