“…The outcomes for physical properties such as ET and shade are sufficient and reliable, according to previous studies [9,30,32]. The model output has been validated in various research (i.e., [30,38]) and its reliability has been proven [44]. This research attempts to validate ENVI-met simulation results.…”

“…The tool generates Typical Meteorological Year (TMY) weather data for the required location, based on field measurements from the nearest weather stations, which is accepted as long as it is within no more than 3 km, according to the WMO measurement instructions [35]. Meteonorm creates hourly time-step weather files in various formats (i.e., EPW and STAT files), that could be refined or coupled with other simulation tools, consistent with accepted accuracy [22,[36][37][38][39][40][41]. The 20th of July was chosen as the simulation day, as it represented both the peak and typical hottest days of summer in the examined site, as shown in Figure 5.…”

In the Middle East and North Africa (MENA) region, studies focused on the relationship between urban planning practice and climatology are still lacking, despite the fact that the latter has nearly three decades of literature in the region and the former has much more. However, such an unfounded relationship that would consider urban sustainability measures is a serious challenge, especially considering the effects of climate change. The Greater Cairo Region (GCR) has recently witnessed numerous serious urban vehicular network re-development, leaving the city less green and in need of strategically re-thinking the plan regarding, and the role of, green infrastructure. Therefore, this study focuses on approaches to the optimization of the urban green infrastructure, in order to reduce solar irradiance in the city and, thus, its effects on the urban climatology. This is carried out by studying one of the East Cairo neighborhoods, named El-Nozha district, as a representative case of the most impacted neighborhoods. In an attempt to quantify these effects, using parametric simulation, the Air Temperature (Ta), Mean Radiant Temperature (Tmrt), Relative Humidity (RH), and Physiological Equivalent Temperature (PET) parameters were calculated before and after introducing urban trees, acting as green infrastructure types that mitigate climate change and the Urban Heat Island (UHI) effect. Our results indicate that an optimized percentage, spacing, location, and arrangement of urban tree canopies can reduce the irradiance flux at the ground surface, having positive implications in terms of mitigating the urban heat island effect.

For long periods last years, the majority of cities suffer from exceptionally hot- dry climate. However, the most urban patterns within these cities are unsuitable for these severe occurrences and raise the value of the Urban Heat Island (UHI). The goal of this study is to see how UHI mitigation options affect outdoor human thermal comfort in three different forms of frequent urban trees patterns in the world’s most populous city in Egypt, Aswan. The ENVI-met model was utilised to assess meteorological using simulation climate program (Ecotect Analysis), buildings and vegetation distribution, using Pupulus Alba. All measurements were taken in a pedestrian walkway at the microclimate case study (case 1. without trees, case 2. distribution trees each 8m total coverage 50%, case 3. distribution trees each 12m total coverage 21.5% were conducted to measure, relative humidity, mean radiant temperature, wind speed, air temperature and prediction mean vote as a key indicator for human thermal comfort. This study provided a better understanding of the role of Urban Heat Island UHI mitigation strategies on human thermal comfort in the outdoor spaces of Aswan’s residential neighborhoods. The simulation results revealed high thermal comfort and discomfort after setting 3 cases for trees pattern for the climate and the possible vegetation (trees patterns). This result indicate that an optimized percentage of urban trees pattern can mitigate (UHI) effect and clear the role that urban trees serve in modifying microclimates.
