    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

    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

    Get PDF
    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

    This study assess the effect of using two nanofluids ; composed of Ferric Oxide (Fe2O3) which is a metalic oxide and Red Clay Brick Waste (RCBW) containing over 60% SiO2 a nonmetalic oxide nanoparticles in ordinary water upon the performance of a basin solar still .An increase in the still productivity was observed for both the tested nanomaterials while the gain achieved with Fe2O3 exceeded that for RCBW at all the concentrations used .For both materials, the rise in concentration adds to the still yield which reached its maximum values ; 11% and 9.5% for Fe2O3 and RCBW respectively at 0.01 vol % then a depltion in the still yield was recorded with additional increase in concentration .The operation of the tested solar still is intermittent as the basin fluid is kept stationary during offshine sun hours . This leads to a continous decrease in thr still productivity over its operating period due to the loose of nanofluid stability causing aggregation ,clustering and gravity aided sedimentation of the nanoparticles .These effects negatively affect the optical and heat transfer characteristics of the nanofluid suspension which determines the rate of vaporization and condensation of water in the still .Over 70% depltion in the still yield relative to that obtained in the first day of operation was recorded in the third day of operation for Fe2O3 nanofluids while four consecutive days of operation were needed for RCBW nanofluids to cause similar effect

    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

    Conservation of Beirut’s Urban Heritage Values Through the Historic Urban Landscape Approach

    Get PDF
    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

    THE IMPACT OF PLASTERING ON THE HYGROTHERMAL BEHAVIOUR OF HISTORICAL SANDSTONE LOCATED IN THE COASTAL REGION OF LEBANON

    Get PDF
    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

    Get PDF
    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

    IMPACT OF BIM ON BUILDING DESIGN QUALITY

    Get PDF
    During last decades, the aim of new technologies was to develop new information systems to automate manual processes. Large-scale projects in the field of construction industry need a different approach to organize and analyze data creating a database without any duplication or redundancy. Building Information Modeling (BIM) is a teamwork process using advanced technologies to generate data modeling. Based on a literature review, the present research proposes a set of hypotheses that links BIM implementation with the enhancement of information sharing capability (ISC) and collaborative decision capability (CDC) in the construction sector of the building industry. Consequently, it relates the degree of BIM use to the design quality enhancement using ISC and CDC as mediators. Towards this end, the research adopts three sets of criteria namely, functionality, form and aesthetic values, and building construction quality as indicators to design quality improvement. Finally, the research proposes a new conceptual model to set the potential relations between the different variables included in the study. Hence it offers several implications for practitioners and decision makers concerning the importance of BIM to enhance the design quality

    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
