“…However, that is why adaptation to climate change considers vegetation as major applications to reducing heat stresses, energy consumption and in turn carbon emissions [18,52,85]. In completion to the green infrastructure, Ayad et al [86] used a coupled simulations workflow for three combined simulation models; microclimate, building energy and climate change. The author investigated the effect of both green and blue infrastructure (GBI) in present and future climates through the climate change projections of the Fifth Assessment Report (AR5) published by IPCC around Al-Mahmoudya channel in Alexandria, Egypt.…”

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.

Regulations corroborate the importance of retrofitting existing building stocks or constructing new energy-efficient districts. There is, thus, a need for modeling tools to evaluate energy scenarios to better manage and design cities, and numerous methodologies and tools have been developed. Among them, Urban Building Energy Modelling (UBEM) tools allow the energy simulation of buildings at large scales. Choosing an appropriate UBEM tool, balancing the level of complexity, accuracy, usability, and computing needs, remains a challenge for users. The review focuses on the main bottom-up physics-based UBEM tools, comparing them from a user-oriented perspective. Five categories are used: (i) the required inputs, (ii) the reported outputs, (iii) the exploited workflow, (iv) the applicability of each tool, and (v) the potential users. Moreover, a critical discussion is proposed, focusing on interests and trends in research and development. The results highlighted major differences between UBEM tools that must be considered to choose the proper one for an application. Barriers of adoption of UBEM tools include the needs of a standardized ontology, a common threedimensional city model, a standard procedure to collect data, and a standard set of test cases. This feeds into future development of UBEM tools to support cities' sustainability goals.

“…Coupling indoor-outdoor has already been a research strategy in the Egyptian context starting from the work of Fahmy et al (2009), but very few of such studies have been achieved to date. Another research gap to be filled is the assessment of the effects of green and blue infrastructure lumped together, on which Ayad et al, (2019) conducted the only published study on an Egyptian case.…”

The formation of urban heat islands (UHI) over cities is the main challenge to the urban environmental sustainability worldwide. To mitigate UHI effects, passive cooling using cool materials and/or greening is thought to be the most effective strategy. As urban greening is relatively nascent in the urban literature, a multitude of research gaps are still to be filled, especially for the cities belonging to the hot arid belt. The present study aims to explore to what extent are three greening strategies (façade greening, roofs greening and urban parks) feasible in UHI mitigation using case study in Greater Cairo Metropolitan Area (GCMA). This task is best achieved through modeling, using the micro-scale numerical model ENVI-met, to simulate the probable outdoor cooling effects of greening for a hot summer day. The results, for this specific case, show that both façade and roof greening would yield up to 0.5 o C average reduction of air temperature compared with the actual case, while the cooling effects of the hypothetical pocket parks may be as high as 7 o C during day time till 15.00 PM, and after that parks would exhibit heat island properties. The study findings may assist in better planning of urban green spaces to increase their cooling potentialities.
