The Impact of Peri-Urbanisation on Housing Development: Environmental Quality and Residents\u27 Productivity in Ibeju-Lekki, Lagos
No full textThis paper assesses the impact of peri-urbanisation on housing, environmental quality and residents’ socio-demography in Ibeju-Lekki peri-urban in Lagos, Nigeria. Primary data was collected through administration of 370 questionnaires to household heads in purposively selected sixteen settlements in the study area while secondary data was sourced from spatial images, land use maps and satellite images of the study area. Quantitative data were analysed using descriptive statistics while qualitative data was analysed using time series and satellite image analysis. The result shows a spatial expansion due mainly to increased housing development, a multi-dimensional environmental and socio-cultural challenges that impact negatively on the quality of living and a literate, high-income group dominance in the selected peri-urban settlements in Ibeju-Lekki. The study recommends the creation of a database to capture the pattern of housing development, residents’ socio-economic demography and infrastructure needs for intervention in policy design for sustainable development
Morphological and GIS-based land use Analysis: A Critical Exploration of a Rural Neighborhood
Get PDFThe significance of neighbourhood in hosting a group of dwellings units and possessing adequate communal facilities could not be overemphasized in the study of people and place relationships. There are two main objectives of this study: (i) to study the neighbourhood’s associated challenges through the size, growth, and land use distribution, and (ii) to investigate the perceived inhabitants’ activities pattern within the neighbourhood. The objectives are explored through a morphological and GIS-based land use analysis of a rural neighbourhood in South-west, Nigeria. The town is studied in three transformation phases, dating back to five decades using ArcGIS version 10.3. The 1st phase spanned between the year 1910 to 1959, while the 2nd and 3rd phases ran through the year 1960 to 1999, and the year 2000 to 2015 respectively. The exploration in this study is to document the diverse neighbourhood challenges, features, and prospects, which remain uninvestigated in the case study area for the past years. In conclusion, human historical and social influences play a significant role in ameliorating the challenges associated with the spatial developments of the settlements. The implication of the study becomes vital to the major stakeholders and professionals in the built environment on the significance of enhancing the sustainable communities in Nigeria
Vernacular Architectural Preservation of Material and Spiritual Interconnected Cultural Heritage
No full textVernacular architecture presents sustainable minimum-impact structures harmonized with their context and inhabitants. Heritage preserved tangible and intangible in material forms, encrypted spiritual believes of humanity\u27s life in dwellings’ organization unveiling the details of our ancestors’ life and world cultures’ connectivity. Instigated by modern-world urbanization, sustainability and cultural diversity issues, the study is researching on cultures connectivity, corresponding to the scale and context of the global cityscape and attempting to synthesize vernacular heritage. The objective of this research is to study indigenous human congruent architectural examples and their relationship with intangible aspects of habitat. This paper will be adopting a qualitative method, by which it aims to study and observe various examples so as to analyze interconnections of Siberian Chums and Native-American Tipi, their design driving forces, settlement of the 2nd century BC- Arkaim and Japanese traditional architecture
The Scale of Public Space: Taksim Square in Istanbul
Get PDFThis article aims at following the traces of the transformation of public sphere in Turkey through its manifestations on urban public spaces with the case study of Taksim Square. In this attempt, the article illustrates how Taksim square, as a public space, has been shaped by struggles between different ideologies, discourses, political decisions and daily activities taking place at personal, interpersonal, local, national, supranational and global scales. Through this way this article also aims at understanding how these contestations at different scales are affecting people, individually and collectively, from daily life practices to political integration. The article also discusses that our daily life practices and preferences are political decisions and our participation in public sphere occurs through those daily actions of the personal spheres. Therefore, the article suggests that a paradigm shift is needed in the design and production of the built environments that will facilitate the coexistence of multiple counter publics.

Identity in Changing Context: Factors of losing Identity in new developed part of the city of Famagusta, North Cyprus
No full textHistorical cities due to its magnificent building in its context have a tremendous influence on the formation of city identity, which is created through the interaction of natural, social and built elements. Unfortunately, modernization after the industrial revolution couldn’t adapt itself to the vernacular area, owing to the fact that cities began to lose their identity and sense of belonging to the environment. The new technology of construction lets the cities to expand itself outside, but in this transformation, some factors which have an influence on the identity of the city have been forgotten. In this research, it is aimed to analysis Physical and social factors which are causing the loss of identity in the city of Famagusta (Gazimagusa). Both qualitative and qualitative methods have been used in this research and the adopted techniques are personal observation, sketches, and comparing new development part of the city with the traditional part. The research will try to answer the question of why urban sprawl could not maintain the identity of the city of Gazimagusa?. This research revealed that Globalization by neglecting historical housing principles is the main factor which threatening the identity of the city
Establishment of space syntax to read urban road network; the case of Sari, Iran
No full textCities have permanent changes as a living organism, where the transformation required in designing a solution for structural and social demands achieving safe and healthy human contacts. Some scholars divide city sustainable development toward two main views, as the building\u27s set are connected by a space, on the other hand, human social actions are linked by urban network interaction. The aim of this paper is to study on the urban road network by the establishment of space syntax logic, this issue is divided into two main parts, as a first part, the study on already existing and the second part is bringing the new suggestions to a more qualified urban road network. Sari city of Iran is selected for this Case Study
Experimental analysis of a flat plate solar collector with integrated latent heat thermal storage
No full textIn the present paper, an experimental analysis of a solar water heating collector with an integrated latent heat storage unit is presented. With the purpose to determine the performance of a device on a lab scale, but with commercial features, a flat plate solar collector with phase change material (PCM) containers under the absorber plate was constructed and tested. PCM used was a commercial semi-refined light paraffin with a melting point of 60°C. Tests were carried out in outdoor conditions from October 2016 to March 2017 starting at 7:00 AM until the collector does not transfer heat to the water after sunset. Performance variables as water inlet temperature, outlet temperature, mass flow and solar radiation were measured in order to determine a useful heat and collector efficiency. Furthermore, the operating temperatures of the glass cover, air gap, absorber plate, and PCM containers are presented. Other external variables as ambient temperature, humidity and wind speed were measured with a weather station located next to the collector. The developed prototype reached an average thermal efficiency of 24.11% and a maximum outlet temperature of 50°C. Results indicate that the absorber plate reached the PCM melting point in a few cases, this suggests that the use of a PCM with a lower melting point could be a potential strategy to increase thermal storage. Thermal analysis and conclusions of the device performance are discussed
Power Quality Improvement by Using Statcom Control Scheme in Wind Energy Generation Interface to Grid
No full text“Electric Power Quality (EPQ) is a term that refers to maintaining the near sinusoidal waveform of power distribution bus voltages and currents at the rated magnitude and frequency.” The power quality is basically customer-centric. The increased focus on utilities toward maintaining reliable power supply by employing power quality improvement tools has reduced the power outages and blackout considerably. Good power quality is the characteristic of a reliable power supply. Low power factor, harmonic pollution, load imbalance, fast voltage variations are some common parameters which are used to define the power quality. If the power quality issues are not checked it will lead to a high electricity bill, the high running cost in industries, malfunctioning of equipment, challenges in connecting renewables. Capacitor banks, FACTS devices, harmonic filters, SVC’s, STATCOM are the solutions to achieve power quality. This paper presents the STATCOM system with the BESS and studies the impact on the power quality in a system which consists of the wind turbine generator, nonlinear load, hysteresis controller for controlling the operation of STATCOM and grid. The model is simulated in the MATLAB/Simulink. This scheme mitigates the power quality issues, improves voltage profile and also reduces harmonic distortion of the waveforms. BESS level out the imbalances caused by real power due to the intermittent nature of wind power available due to varying wind speeds

The article proposes an ethical approach which can go beyond and above professions and their limited professional interests to be able to prevent the unethical professional conducts
Courtyard Housing in China: Chinese Quest for Harmony
No full textThe Chinese have lived in single-extended-family courtyard houses in many parts of China for thousands of years. The earliest courtyard house found in China was during the Middle Neolithic period (5000-3000 BCE). The courtyard form signifies Chinese quest for harmony with nature and in social relationships. However, the 20th century was a significant turning point in the evolution of Chinese courtyard houses; this paper provides an overview of this transition. It starts by briefly introducing traditional Chinese courtyard houses and their decline since 1949, it then examines the emergence of new courtyard housing in Beijing and Suzhou since the 1990s, and then it evaluates the new development of Chinese-style courtyard garden villas in/around these two cities since the 2000s, such as Beijing Guantang and Suzhou Fuyuan villa estates. They are explorations of a new way to honour Chinese architectural history and philosophy, meanwhile, incorporating Western interior design principles to meet modern living requirements. This architectural acculturation represents Chinese sustained quest for harmony in their art of living. The paper finally proposes four designs of new courtyard garden houses for future practice
