“…Studies on UHI mitigation strategies, such as those using green roofs [27,28], cool materials [29], vegetation [30,31], and water sources [32,33], have received a lot of attention recently. Adopting mitigation techniques is crucial for both large urban regions like cities as a whole and smaller localized urban locations like urban canyons [34,35].…”

It is well-known that the occurrence of urban heat islands (UHI) is related to climate change and urbanization. Urban locations experience local overheating throughout the summer, which is uncomfortable and it has a detrimental impact on buildings ability to consume energy. In this study, a methodology was developed to assess the urban heat island effect in a localized urban area and to evaluate the effects of different kind of mitigation strategies. The numerical model was developed using the ENVI_met tool and it was calibrated with weather data and albedo measured inside the examined area and near the simulated domain. The procedure adopted overtaking the limit of the software in reproducing accurate weather conditions without calibration. Finally, combination of extensive mitigation strategies (cool pavements, greenery, grass pavers) with local strategies (shading) were investigated. An experimental and numerical investigation of a square in Rome was exanimated to evaluate the possible solution for mitigating outdoor air temperatures. Results of the paper affirm that an intervention on the pavement albedo and the increase of vegetation inside the square, lead to an improvement of the air thermal conditions. In particular, the application of the grass pavers would lead to the greatest benefits. A maximum decrease in the air temperature of 1.2 °C was obtained through the application of cool material, while the reduction reaches up to 2.88 °C when a grass paver is applied. The improve of the vegetation can bring to a maximum decrease of 1.46 °C, while the use of shading projecting roof allows a reduction up to a maximum of 2.07 °C.

Currently, there is a lack of accurate simulation tools for the thermal performance modeling of courtyards due to their intricate thermodynamics. Machine Learning (ML) models have previously been used to predict and evaluate the structural performance of buildings as a means of solving complex mathematical problems. Nevertheless, the microclimatic conditions of the building surroundings have not been as thoroughly addressed by these methodologies. To this end, in this paper, the adaptation of ML techniques as a more comprehensive methodology to fill this research gap, covering not only the prediction of the courtyard microclimate but also the interpretation of experimental data and pattern recognition, is proposed. Accordingly, based on the climate zoning and aspect ratios of 32 monitored case studies located in the South of Spain, the Support Vector Regression (SVR) method was applied to predict the measured temperature inside the courtyard. The results provided by this strategy showed good accuracy when compared to monitored data. In particular, for two representative case studies, if the daytime slot with the highest urban overheating is considered, the relative error is almost below 0.05%. Additionally, values for statistical parameters are in good agreement with other studies in the literature, which use more computationally expensive CFD models and show more accuracy than existing commercial tools.

“…Recent studies on courtyards and their thermal environment have demonstrated their ability to provide a cool microclimate in the summer [5,6], especially in hot and humid regions [7]. Diz-Mellado et al [8] used thermal comfort modeling to highlight the thermal performance and usability of courtyards in hot climates and demonstrated how courtyards are used to promote thermal comfort in large spaces by casting shadows.…”

The campus courtyards in the Lingnan area are commonly used spaces. Therefore, their thermal comfort is highly important for improving user satisfaction. This study conducted field research on 18 courtyards in four universities in Lingnan to explore the effects of their architectural design factors on the thermal environment. Relevant studies have proved that courtyards are cost-effective in microclimate regulation, and individual factors such as the scale and openness of the courtyards have also been shown to have an effect on the thermal comfort of the courtyards. This study synthesizes multidimensional architectural design factors to explore and analyze the thermal environments of college courtyards. Physiologically equivalent temperature (PET) is selected as the thermal comfort evaluation index for the study and the conclusions are as follows: (1) The thermal environment is the most important factor influencing visitors to the courtyards (22%), and good thermal comfort improves the efficiency of using the college courtyards; (2) the courtyards have a positive microclimate regulating function, and a cooling effect occurs in 80% of them; and (3) the floor location, type, orientation, and sky view factor (SVF) of the courtyards are the main design factors affecting the thermal environment and PET. The first three factors were negatively correlated with PET (p < 0.05),and SVF was positively correlated with PET (p = 0.651). Passive courtyard design strategies are presented based on the findings of this study.
