A study on the strategies of Park City construction of Chengdu from the perspective of urban heat island mitigation | Author : Lichen Wang | Abstract | Full Text | Abstract :In the process of urbanization, various urban problems have become increasingly prominent, and the heat island effect is one of them. The expansion of urban land, the increase in construction intensity and the increase in population make the urban heat island effect even worse. The construction of park cities improves the ecological environment of the city and is considered to have a positive effect on alleviating the heat island effect, but it is not clear whether it has such an effect or not. This article explores whether the construction of Park City can help to improve the urban thermal environment effectively, and also, seek solutions for how to improve the construction of park cities so that the heat island effect can be better mitigated. Landsat8 remote sensing images in 2014 and 2019 were used to estimate the fractional vegetation cover (FVC) and land surface temperature (LST) in the Third Ring Road of Chengdu. Land use data were also introduced into the study to analyze LST changes in different surfaces and FVC.The results indicate that: (1) the area of the heat island zone in the Third Ring Road of Chengdu decreased by 0.91% from 2014 to 2019, and the area of the cold island zone increased by 17.89% ; (2) the urban blue-green space is conductive to mitigating the urban heat island effect, in which the water provides the best mitigation, while impervious surface and bare land may aggravate the urban heat island effect; (3) the FVC in the area of the Third Ring Road in Chengdu is on the rise as a whole, and there is a significant negative correlation between FVC and LST (p < 0.01). Based on the above results, this paper shows that Park City construction is beneficial to alleviate the urban heat island effect, and more attention should be paid to blue-green space layout and quality, along with urban ventilation and FVC control. Our results provide useful input for green space planning and the construction of Park City in the future. |
| Development of A User-Centered Design Framework for Palliative and Hospice Care Patients for a Better Quality of Life Experience | Author : Shahira Assem Abdel-Razek | Abstract | Full Text | Abstract :Goal Three of the Sustainable Development Goals emphasizes the concept of “leaving no one behind”; a model for inclusivity and coherence. Amongst those that are often “left behind” are patients at the end stage of their life due to a terminal illness or a medical diagnosis. These are often left to die without thought to the quality of life that they receive before their demise, and many experience this stage at home due to fear of expenses, or in a best-case scenario at a hospital to help alleviate or manage pain. In many places worldwide, this is where palliative and hospice care come in and focus on the End-of-Life care provided to patients who fit the criteria.
The number of architecture and design related studies in this field are not numerous, and those that are there do not focus on the patient as a user with rights, but merely as a patient that is there. The concept of a user-centered design is forgotten in midst of all the pain and suffering of all concerned, namely, the patient, his beloved, and his caregivers. However, focusing on this nexus at the core of the design project may help promote this painful and stressful time in life and induce serenity and acceptance in a time that is often dark and ominous. This research aims to develop a design framework for places that deal with End-of-Life care and how to provide a better quality of End-of-Life experience for terminally ill patients. |
| Cultural Landscapes Preservation at the Interface of Urban Planning and Sprawl | Author : Laouar Imene | Abstract | Full Text | Abstract :From ancient times, the sea has played a key role in shaping and generating settlements and cities. The history of civilizations has been marked by the cultural development of human societies along coastlines. Accordingly, these territories are harbor of an important coastal heritage; that plays a pivotal role in maintaining the link between the past and the future. In fact, while cities grow and their populations increase, their planning becomes a challenge for sustainable development. Through different forms and mechanisms, coastal sprawl is materialized, by the massive occupation of populations and industrial activities along coastlines. In this vein, coastlines endure many conflicts, which lead to the degradation of cultural and natural resources and may result in loss of cultural identity associated with the presence of cultural landscapes. The paper aims, to discuss planning approaches and challenges related to managing cultural and coastal landscapes, facing the impact of coastal sprawl. The paper is based on a landscape analysis; it interviews the urban, social, juridical and morphological frame. An understanding of urban sprawl through the lens of Annaba’s coastline is required for its implication as a social support of the identity and the history of the city. The paper also examines how the coastalization affects the cultural heritage based on the monograph of one of the valuable French colonial constructions in Algeria. Lastly, the study demonstrates, some key opportunities for advancing future adjustments, and coastal management approaches. For instance, new tools and more appropriate methodologies that combine the preservation of the coastline and the preservation of the cultural heritage. |
| The Role of Value Engineering in Government Housing Projects in Developing Countries to Improve Value | Author : Mahmoud Zaki | Abstract | Full Text | Abstract :Government housing projects are among the complex issues facing developing countries’ governments. There have been many attempts to solve problems related to this issue and a lot of effort has been made in this direction. The main problem is lowering the cost of lodging, without sacrificing its quality and the effectiveness by which it fulfills the needs of its occupants. This became possible upon the use of the value engineering technique. Value engineering is an effective tool used to solve problems related to housing, by lowering cost on one hand and sustaining or even ameliorating quality and performance.
The purpose of this study is to try to identify a series of proposed solutions and value indicators and to describe their role in improving value in government housing projects. This process may assist the designer in choosing and managing, value indicators during the creative phase, using references from the literature and the analysis of case studies.
The literature review identified the reasons for high costs and poor performance, which are often a result of a misunderstanding of the fundamental principles of design criteria and value indicators, followed in government housing projects. The review also pinpointed the most important considerations that improve value.
Results obtained in this study feature the positive effects of methods under the umbrella of value engineering, applied in government housing projects. It was found that savings of 15% to 40% can be achieved in the total cost of a certain project, using this technique. Generating ideas in the creative phase is one of the most important stages in value engineering studies. A set of value indicators and proposed solutions in the form of a checklist were derived and can be used in the future, during the creative phase of value engineering studies in the initial design stage of government housing projects. |
| Towards a Comprehensive Climate Adaptation Framework for India’s Port Infrastructure and Operations: Lessons from Global Best Practices | Author : Pushp Bajaj | Abstract | Full Text | Abstract :The ever-growing impacts of climate change such as extreme heat, more frequent heavy precipitation events, intensifying tropical revolving storms, and sea level rise continue to pose major threats to India’s critical maritime infrastructure. As the country moves towards its ambition of becoming a leading Blue Economy of the world, a wide range of initiatives have been taken by the central and state governments to expand the maritime sector with a specific focus on the transport sector. However, there is little emphasis being paid on protecting the existing and planned seaport infrastructure against the deleterious impacts of climate change. None of the major ports in India have a dedicated climate action strategy and climate adaptation finds no mention in the policy documents pertaining to the maritime transport sector. In this context, this paper aims to highlight the need for a comprehensive, holistic and dynamic climate change adaptation strategy for India’s port infrastructure including support infrastructure and supply chains. The adaptation strategy, at the individual ports’ level and the national level, must be preceded by rigorous risk assessment studies to identify and prioritise the major challenges arising from climate change at the local level. The paper draws upon international best practices in climate risk assessments and adaptation measures to provide a way forward for Indian ports |
| Challenges facing components reuse in industrialized housing: A literature review | Author : Lisco Margherita | Abstract | Full Text | Abstract :Concerns over the earth’s ability to sustain itself over the long term as a consequence of human consumption of natural resources points towards sustainable development. Since a large proportion of human consumption is linked to buildings and construction, this means managing the construction process in more sustainable ways. Strategies that target greater material efficiency and which promote circular economy concepts are among several approaches that are gaining in popularity. The adoption of life-cycle thinking and practices in design, construction and end of life through the reuse of construction components and materials is one such action to achieve a sustainable built environment. Reuse is not a new concept and technical solutions do exist; however, practical realization is hampered by many interrelated challenges. This review paper is the result of a literature review for an exploratory study that aims to identify obstacles to the reuse of building components and materials. The context is industrialized housing, particularly timber-based construction, as this is a sector where modern manufacturing and onsite practices have become established. The main obstacles identified and corroborated in the literature, along with their potential solutions, are summarized and conclusions drawn on the future direction of research needs. |
| Towards Programs Sustainability: Assessment of Institutional Determinants for Effective Community Participation in Development Programs in Tanzania | Author : Daniel Wandera Clief Naku | Abstract | Full Text | Abstract :This paper brings to the fore an assessment of institutional determinants for effective community participation in development programs for the case of Tanzania. It is highly acknowledged in various scholarly literature that there is a strong link between community participation and development programs. In fact, literature shows that community-based development programs that have allowed community members to be fully involved in various programs have been successful when compared to those where community members are seen as spectators.
However, in order for community members to take part in the programs, there are several determining factors, ranging from socio-economic, socio-cultural to institutional based factors.
This study therefore sought to assess institutional determinants with the aim of identifying the major institutional determinants capable of influencing effective community participation in development programs. The study used four programs that were categorized as Locally Funded, Government Funded, Donor Funded and Joint Funded development programs. A combined sample size of 316 participants from all the four programs was employed. Collected data were analyzed through the within-case analysis and the comparative analysis approaches.
Results of the study revealed that program benefits, objectives and leadership were the major institutional determinants for promoting effective community participation in development programs. when compared to methods used in the other three examined programs. Hence, the study concluded by emphasizing on the need to ensure these institutional based factors (program benefits, objectives and leadership) should always be given due attention in any development program. |
| Rural Regeneration in Egypt: A Review of Existing Typologies in Borderline Areas | Author : Shahira Assem Abdel-Razek | Abstract | Full Text | Abstract :Tracking rural areas and studying them may not be an easy task. The concept of whether the area at hand is urban or rural could be simple, but lately rural areas could carry many features that may deviate the definition into one which is unclear. In urbanized rural development, reversing the urbanization spotted may not be the ideal way to go, urban developers often suggest that to go back to the roots is to regenerate the area back into rural, however, regenerating rural areas using rural parameters and definitions may not be what the urban area in hand needs and the changes and challenges that are facing rural communities in Egypt need to be understood before any plan can be deemed as effective or even worthwhile The rapid increase in urbanization and how it affects agriculture land, shorelines, and rural land, has affected badly the rural capacity, and led to a constant threat of overhaul in place of towns, cities, and other urban activities. However, rural areas are the lungs of the planet alongside forests and other green areas and having them diminish substantially will lead to an inevitable catastrophe. Regenerating rural areas should focus on revitalizing and embedding them into the social, cultural, and economic structure of the region, however, it may not always involve turning them back to what is commonly termed as rural.
This research attempts to review and discuss the meaning and definitions of rural regeneration with a view to propose a strategic plan to regenerate borderline areas in Egypt. |

| Sustainability and diversity in the architecture of intercultural universities in Mexico | Author : Peña Dalia | Abstract | Full Text | Abstract :Intercultural universities in Mexico have been created since 2001, currently there are 12, the last one to be created is the Intercultural University of Baja California in San Quintin. These universities are governed by an intercultural model that states that they must incorporate linguistic expressions and manifestations and knowledge of indigenous peoples in their substantive functions as well as in their scientific activity, but some of them have also incorporated cultural and sustainable expressions in their architecture. In this sense, there are experiences of these universities that incorporate different cultural and sustainable elements in their architecture. Based on the above, this study presents some experiences of Intercultural Universities in Mexico that recover cultural and sustainable elements in their architecture. Methodologically, we resorted to reflexive ethnography by conducting several interviews with the architect of the UICEH. Some of the results obtained in the research show the importance of how, through the architectural spaces, elements of interculturality and sustainability are embodied, including some related to local cultures where the Universities have an impact. |

| Turning Urban Streets from Infrastructures into Living Places Early Research Outcomes of a Case Study in Prato, Tuscany | Author : Gabriele Paolinelli | Abstract | Full Text | Abstract :In the second half of the twentieth century urban landscapes were affected by heavy infrastructural development. With regard to streets, managing the growing fluidity and speed of motor vehicle flows has been a priority for most designers. Nowadays there are multiple driving forces behind a transition that could accommodate different uses within the streets, primarily the cultural, social and economic exchanges that streets faciliated in the past but that have been lost over time. In the spreading practice called “shared street” most signage and traffic lights can be removed to permit the self-regulated and spontaneous circulation of all users and vehicles. This paradigm is discussed with regard to its potential to strengthen urban landscape identity, ensuring accessibility, redefining uses and practices within the street, reducing injuries and misbehaviour, and offering real and perceived safety to all users. “Back to the street” is an ongoing design research project dealing with integration strategies for different kinds of urban streetscapes. Which design features are necessary to encourage a change in attitude, speed and hierarchy for street users? How can these features positively affect urban landscapes in general and the liveability of streets first and foremost? The research attempts to answer these questions by considering street design as a means of triggering the effective enhancement of urban public spaces. The paper is based on the case study of Via San Paolo in Prato (Tuscany) and presents a set of quality requirements for street design such as plant integration, water drainage, and comfortable paths for both cyclists and pedestrians. As the design for separate flows cannot fulfill all the quality features in Via San Paolo, mostly due to its varying width, it is assumed that the “shared street” can replace it in order to enhance community life within the streets while promoting local sustainable mobility. The research examines two options: sharing the street in narrow stretches or along its whole length. A preliminary comparison is proposed to discuss the earlier research outcomes |
| Sustainable Urban Development: Bioregionalistic Vision for Small Towns | Author : C K Surekha | Abstract | Full Text | Abstract :Cities and towns are the social constructs in regional settings. They physically manifest and exist as power centres through various layers of culture, economy, politics, and religion. There was a symbiotic relationship between the ‘setting’ and the ‘construct’ in the past. With time and advent of technology, haphazard developments led to degradation of ecological systems and have become a confronted affair. Global warming, its adverse effects and the constant references to the words ‘sustainability’ and ‘resilience’ pose questions on the existing planning models. Small towns experiencing a tremendous pressure of urbanisation and rich in natural resources, coherence and identity are fast changing. An indispensable change in the planning models is necessary to mitigate this existential crisis and condition the emerging urbanism in small towns sustainably. This paper unearths the role and possibilities of bioregional planning as a sustainable urban development paradigm and suggests few indicative parameters for envisioning bioregionalism in small towns. |
| Rejuvenation in rural Ireland in response to the COVID-19 induced urban-to-rural migration phenomenon | Author : Shreya Sen | Abstract | Full Text | Abstract :The aim of this paper is to discuss the paradigm shift in residential choices induced by the COVID-19 pandemic in Europe. Firstly, the resilience of the rural regions belonging to the Northern Periphery and Arctic Program will be explored—the challenges brought about by COVID-19 within their tourism sectors, and the opportunities for rural revival generated by the current shifts in workplace mobility. The paper will then delve deeper into the case study of Ireland. The pre-existing issue of Ireland’s one-off housing and suburban sprawl will be explored, and the extent to which the regional plan “Our Rural Future” will tackle these issues by optimizing building density and dwelling typology in the post-COVID-19 era. |
| Research and application of climate-responsive design of traditional vernacular houses in Chaoshan, China | Author : Jinglei Li | Abstract | Full Text | Abstract :Chaoshan vernacular house is an important branch of Lingnan traditional houses in South China, with a long architectural history and excellent climate responsiveness to the hot-humid climate. The modern rural houses learn the traditional experiences mainly in the form but fail to inherit the climate-responsive design and wisdom of the traditional houses. This study took the widely distributed Xiashanhu houses in Chaoshan as the object, generated 128 Xishanhu parametric models by combinations of various parameters on design factors of building, opening, shading, construction, and street layout, and investigated the climate-responsive design techniques by using the parametric methods. The results show that the hall width, room width, cornice height, orientation, and wall construction are the key climate-responsive design factors oriented towards thermal performance of Xiashanhu houses. The optimized designs are: the smaller hall width (4.05m,4.32m,4.59m), the smaller room width (2.7m,2.97m,3.24m), the larger cornice height (4.92m,5.1m), the orientation ranged from 30° north by west to 30° north by east, and the brick and concrete wall. The rationality and validity were verified by applying the optimized climate-responsive designs to the re-construction of a new rural house. Compared to the original case, the thermal performance is significantly improved by 5.18-9.98%. A detailed discussion was also provided on considering the actual situation and needs of the modern buildings in the process of "using the past for the present." This study is believed to provide valuable references for the research and modern applications of climate-responsive designs of traditional vernacular houses. It also contributes to the preservation of architectural and cultural regional characters and the inheritance of architectural climate responsiveness in contemporary times. |
| Analysis Of Solar Radiation Towards Optimization and Location Of The Urban Blocks In The Neighborhood Units | Author : Omid Veisi | Abstract | Full Text | Abstract :Increasing population causes Energy consumption and environmental pollution. It is essential to consider renewable forms of energy, especially solar power, to reduce energy consumption. This requires attention to energy issues in the early stages of urban design and practical and creative solutions for more efficient use of this type of energy. This study aims at calculating the annual solar radiation at a city scale through a novel process and methodology. In this regard, artificial intelligence algorithms and satellite data can help maximize the amount of sunlight in neighborhoods and urban blocks in neighborhood units during the development process. In the simulation process, location, and optimization of the urban form, it is necessary to consider the limitations and resources for field study and simulation of urban blocks. Therefore, in this study, Farhangian neighborhood in phase 1 of Kermanshah, Iran, which has a good level of structural diversity and lends itself to field studies, was selected and studied at neighborhood and urban block scales. The case study indicates the significant role of calculating and optimizing the patterns of urban blocks to achieve maximum solar energy. Estimates at different levels show that urban block variables effectively access solar radiation energy and, given various scales of development - from macro-scale spatial planning to micro-scale local design - can improve energy intake by 3 to 5 percent. Accordingly, the results show that to accelerate the calculation of energy at the planning scale, the use of 2.5D locating model and 3D optimization contribute to achieving the maximum or minimum solar radiation, respectively. On the other hand, this method can be used to organize calculations and planning for maximum absorption of solar radiation at different stages of development. |
