“…Stathopoulos et al [7], in their review of urban SWT technologies, argue that, although Vertical-Axis Wind Turbines (VAWTs) tend to be quieter and visually pleasant, the Horizontal-Axis Wind Turbines (HAWTs) remain a preferred choice for urban applications. This is because VAWTs remain commercially less cost-efficient than HAWTs.…”

While the vast majority of the wind energy market is dominated by megawatt-size wind turbines, the increasing importance of distributed electricity generation gives way to small, personal-size installations. Due to their situation at relatively low heights and above-ground levels, they are forced to operate in a low energy-density environment, hence the important role of rotor optimization and flow studies. In addition, the small wind turbine operation close to human habitats emphasizes the need to ensure the maximum reliability of the system. The present article summarizes a case study of a small wind turbine (rated power 350 W @ 8.4 m/s) from the point of view of aerodynamic performance (efficiency, flow around blades). The structural strength analysis of the blades milled for the prototype was performed in the form of a one-way Fluid–Structure Interaction (FSI). Blade deformations and stresses were examined, showing that only minor deformations may be expected, with no significant influence on rotor aerodynamics. The study of an unorthodox material (PA66 MO polyamide) and application of FSI to examine both structural strength and blade deformation under different operating conditions are an approach rarely employed in small wind turbine design.

“…In the urban area the oscillating bodies or structures can be placed to harvest the energy where the wind velocities are relatively higher. Recently, Stathopoulos et al (2018) and Micallef and Bussel (2018) showed that the suitable places for the devices to install in the urban areas and harvest the energy from the wind.…”

An experimental setup is constructed to harvest energy from wind by means of oscillating of a body, structure or even trees. A vertical stem which can oscillate or bend is connected with a rack and pinion and finally pinion is connected with generator to harvest the electrical energy. Once the force is applied on the top of the stem, the connecting wire pulls the rack and pinion is in rotary motion and generates the power. The experiments are carried out for both applied static force and wind assist dynamic force. The experimental results show that the forces exerted on the stem are very much influenced by the stem height, the rack length for power generation. The results from wind assist experiments reveals that the sail size and the materials of both stem and sails play vital role on power generation. The constructed setup shows a good prospect on power generation from wind specially the places like highways, urban areas or any other places where the tree or any other object or structure oscillate.

“…Therefore, applying the local identity is one of the most important issues to protect the heritage village's features, conserve the local traditions, and investigate the village regarding historical tourism purposes. Furthermore, climatic conditions must be taken into account when designing the heritage village in order to employ the local natural resources, such as solar design, shading strategies (Ghosh andNeogi 2018, Luo, Li et al 2018), and urban wind energy to provide efficient natural ventilation for the heritage village ( Stathopoulos, Alrawashdeh et al 2018). The design of Al-Qahad heritage village must take into account the local climatic conditions and the original urban and architectural identity.…”

This paper investigates and analyses the redesigning of a heritage village in the southern region of Saudi Arabia to determine the impact of sustainable design strategies and green open spaces for the village rehabilitation. Heritage village development is an important step to consider for sustainable urban planning and design due to its influence in urban development, the local economy, and historical conservation. Al-Qahad heritage village has been selected as the case study due to its involvement with different historical domestic buildings, military castles, and mosques and its location on the main highway between Albaha and other regions. Furthermore, this heritage village reflects in its urban identity the local environment, social culture, and local construction materials and vernacular architecture. The applied approach involved visiting Al-Qahad heritage village for (a) analysis of the site and environmental conditions, (b) mobility survey analysis, and (c) the application of urban sustainable design strategies for redesigning Al-Qahad heritage village. The site visit included a physical survey to determine the current condition of buildings regarding heights, conditions, land use, and construction materials used. The output of the study is to redesign the heritage village including suggesting some other urban facilities, such as a museum, hotel, and other social activities to attract visitors and rehabilitate the village. The study highlights the importance of many urban sustainable design strategies that can be applied in other heritage villages in Saudi Arabia to protect and conserve the historical buildings and invest in these facilities for tourism purposes. Saudi Arabia is a nation rich with heritage villages, which are found across the country especially in the southern region. The study concludes by offering several recommendations for developers and investors.
