“…Due to increase in population that are expected to live in urban areas, as well as, the increase in air temperature because of the changing climate [115], it is crucial to establish an adaptive and responsive thermally efficient built environment by means of implementing passive design strategies at both building and urban scales. At the urban scale, reducing energy consumption in buildings and alleviating the urban canyon temperature is an integration of several passive design strategies such as trees [3,59,60,116], green roofs [69,73,117,118], green walls, and the fabric of local micro-climate scale [44,[119][120][121]. Based on these studies, the energy consumption of the whole examined urban forms and the housing typologies is proposed to be passively reduced through design, and the remaining energy demand can be met by renewable energy systems.…”

Since the mid-1970s, urban development in Egypt has sprawled far from the distinguished compact arid built environment, as the court-yarded housing typologies that completed the vernacular picture of desert architecture have been discarded in the early 20th century. This has motivated urban microclimate research in Egypt. The main objective was initially to improve outdoor thermal comfort. Therefore, Egyptian research started with assessing different existing patterns for the sake of climate responsive and sustainable urban design practice characterized with low carbon, thermal comfort and energy efficiency in such a hot arid conditions. That is why the review workflow of this article has followed a design progress workflow that led to solving design complexities with regard to generating housing urban forms on a microclimate basis rather than an article regular review workflow in order to extract the research gaps and conclude insights. After discussing a general framework for generating housing sustainable design identified from the concluded gaps, the main conclusion is a vision and a call to integrate the Urban microclimate-Building passiveness-Renewables design dimensions, UBR, towards the evolution of a new era of energy efficient housing typologies and a 5th generation of Egyptian sustainable cities where the 1st generation of new Egyptian cities started 1970s.

“…See figure 8.The city went through a series of systematic destruction after ISIS took control of it in 2014. As a result of the military operations that the city witnessed to liberate it from the organization, the city was subjected to massive destruction, reaching 80% in its right part, which represents the originality in its heritage, roots, and architecture, which is the real starting point for the restoration of Building the features of the traditional city as the original and important aspect inherited by the city, which must be preserved on the one hand and repurposed in the construction, reconstruction and development of the city as a whole on the other hand [35]. It is also known that the urban planning process for new cities is easier than re-planning the existing cities, so how if they have gone through crises represented by wars, pollution, or others [36].…”

The research attempts to shed light on how to invest the philosophical and intellectual concept of the event in preparing the development plans for the city. Based on it, there are three strategies to read the event (Explanation, Interpretation, and Deconstruction) that are regularly responded to it with three strategies represented by (Revitilaization, Renewal, and Reform). Through the use of reading and response strategies, and the corresponding planning policies represented by: preservation, rehabilitation, and redevelopment. The research adopted an analytical and descriptive methodology for some world experiences for the eventful cities, such as Warsaw, which reflects (Explanation - Revitilaization) and used preservation, Bilbao, which reflects (Interpretation - Renewal) and used rehabilitation, and Tianjin, which reflects (Deconstruction - Reform) and used redevelopment. In an attempt to benefit from these experiences and derive some indicators for each strategy. By applying the derived indicators to the traditional Mosul city, it concluded that the most appropriate strategy for the reconstruction of this city is the strategy of Explanation – Revitalization, which represents preservation because the destruction of the city was intending to crush the historical and cultural value of the city and destroy the local and national identity.

“…Providing an area for a courtyard in buildings to facilitate such purposes has been of interest to building designers and researchers. The proportion and shapes of courtyards have drawn research attention, and a series of studies on this topic confirm that various configurations of courtyard proportions, building geometry, and shading solutions can vary the sunlit area of courtyards and affect the cooling or heating energy consumption of buildings (Soflaei et al 2017, Al-Hafith et al 2017.…”

Selecting a building layout is a fundamental task in the early stage of the architectural design process. High thermal mass buildings with well-insulated envelopes are a common solution for colder climates; however, thinner wall construction and lower mass in most tropical architecture means that a well-designed building layout with good consideration of contextual factors is essential to enhance passive cooling and to decrease heat gain by solar radiation. Building layout factors of perimeter and wall surface area are pivotal in long-term energy utilization. This simulation-based research employs Sketchup, Openstudio, and SPSS to investigate the effect of surface solar radiation on indoor air temperature and sensible cooling energy of 17 geometries with and without a self-shading feature under the identical space volume, floor area, and climatic conditions of Bangkok. The simulation conducted in two phases (with and without an active cooling system) revealed that the lower the F/W ratio is, the lower the DBTindoor-annual and operational cost of the A/C system. The circular plan with the highest F/W ratio (0.47) has the lowest annual wall solar heat gain and DBTindoor-annual (29.43°C), and saves approximately 10% of air cooling energy demand compared to the square design (F/W=0.42). The layouts with S/W ratio less than 2.4 are less effective in lowering the DBTindoor-annual and active cooling energy demand than those with S/W greater than 2.4. It is concluded that the self-shading designs (S/W<2.4) may face challenges due to greater wall surface area and receiving more diffuse solar radiation.
