Architectural Planning

In the architectural planning and design, the commonly used architectural layout forms are determinant, diagonal, etc. Because of its centralized and symmetrical layout form, determinant architecture has been widely used in urban architectural design. Due to the high density of multi span buildings, the ventilation effect is not good, so this paper mainly studies the influence of multi span building layout on the wind field of urban ordinary residence. In order to optimize the wind environment of the building, a 7-story residential area was modeled and calculated by CFD. Through the analysis of wind field characteristics at different building heights, the results show that the total wind speed in Z direction of the building is the smallest, about 3.354 m/s; At the same time, the overall wind pressure values are within 5Pa of the standard wind pressure difference, but we still need to pay close attention to the possible environmental impact at the outlet of the determinant residence.

By analyzing measurements of the thermal environment of a qilou (arcade building) street, this study used the relative warmth index (RWI) to evaluate the thermal comfort in the colonnade space of a qilou. The analysis of the influence of the temperature, humidity, and wind speed on the thermal comfort in the colonnade space of a qilou street was conducted, and it was shown that the ambient wind speed had a strong influence on the RWI, indicating that a proper increase in the wind speed positively affected thermal comfort in this space. Then, this study also analyzed the effects of different forms of qilou streets on the wind environment by employing computational fluid dynamics (CFD) and summarized the architectural design measures that can improve the thermal comfort, including adopting back chamfer, street gaps, and the appropriate sizing of building components. It was concluded that the wind environment of a qilou could be optimized in terms of these measures, and the average RWI value decreased by 0.06, effectively enhancing the thermal comfort in the colonnade space. The research findings are applicable toward designing a thermally comfortable environment in the transitional space.

Through FLUENT numerical simulation, this paper is aimed on studying the influence of outdoor wind environment on indoor environment. We found that building height, building layout format and opening format in the wall are significant impacted on indoor natural ventilation. At the three-fourth height of building, if the building layout and housing opening is stagger, it can get high-quality indoor natural ventilation and more evenly indoor wind field.

Based on large amount of meteorological wind field records observed in Wenzhou district, this paper analyzed the annual maximum wind speed (maximum 10 minute mean wind speed), annual extreme wind speed (maximum 3 seconds mean wind speed), reference wind pressure and wind field characteristics of typhoon in Wenzhou. The results shows that the annual maximum wind speed have a decreased trend on the whole in different areas of Wenzhou, and the trend in coastal area is more obvious than that in inland areas; the annual maximum wind speed in different areas of Wenzhou is unsteady and the typhoons have great effect on it; the value of reference wind pressure in Dongtou is greater than the value given by the design load code of China (GB50009-2001, 2002), but the values of other areas are less than the value of Code. Based on the wind field of three typhoon records, some significant results about the variation and routine characteristics of typhoon are also discussed.

Key Parameter

Estimation of maximum wind speed associated with tropical cyclones (TCs) is crucial to evaluate potential wind destruction. The Holland B parameter is the key parameter of TC parametric wind field models. It plays an essential role in describing the radial distribution characteristics of a TC wind field and has been widely used in TC disaster risk evaluation. In this study, a backpropagation neural network (BPNN) is developed to estimate the Holland B parameter (Bs) in TC surface wind field model. The inputs of the BPNN include different combinations of TC minimum center pressure difference (Δp), latitude, radius of maximum wind speed, translation speed and intensity change rate from the best-track data of the Joint Typhoon Warning Center (JTWC). We find that the BPNN exhibits the best performance when only inputting TC central pressure difference. The Bs estimated from BPNN are compared with those calculated from previous statistical models. Results indicate that the proposed BPNN can describe well the nonlinear relation between Bs and Δp. It is also found that the combination of BPNN and Holland’s wind pressure model can significantly improve the maximum wind speed underestimation and overestimation of the two existing wind pressure models (AH77 and KZ07) for super typhoons.

Post Disaster

The need for temporary housing in natural disasters is an important issue for people to develop. During this period, post-disaster accommodation needs are often planned with temporary housing applications that require rapid installation and where the minimum needs of inhabitant can be met. Decisions to be taken in the residential area; can range from the choice of urban relations to the architectural design of temporary residences and can affect the resident's quality of life. A temporary home that will resist a recurring disaster should be a design suitable for climate conditions, close to the adequacy of basic needs in containers, security, and access to urban infrastructure, sustainability of materials, sociality, health and education facilities. In this context, environmental and architectural evaluation of Van and Onagawa container settlements planned after the major earthquakes in 2011 reveals the essence and importance of the study. It also aims to analyse and compare architectural and urban decisions in these settlements, creating a checklist for projects made with the principle of planning and design before future disasters.

This paper examines how the architectural, social, and cultural heritage of the United Arab Emirates and other Gulf countries may contribute to better development of this region’s lived environment. Modern urbanism has largely neglected heritage in architectural design and in social and private spaces, creating inauthentic places that foster a hunger for belongingness in the UAE’s built environment. The paper reviews recent urban developments in the UAE and the Gulf Region, and identifies elements of local heritage that can be incorporated into contemporary planning and design. It proposes that adapting vernacular architectural heritage to the modern built environment should not be the principal goal for heritage-informed design. Instead we may examine the social processes underlying the traditional lived environment, and aim for social sustainability based on the lifeways and preferences of local peoples, especially in kinship and Islamic values. Among the most promising precedents for modern social sustainability are social and spatial features at the scale of the neighborhood in traditional Islamic settlements. Interviews with local Emiratis will also recommend elements of traditional knowledge to modern settings.
