“…Architectural diversity comes from various spatial characteristics identified in urban space, such as geometry, orientation, urban structure, and materials [17]. Spatial diversity is also accompanied by thermal diversity, defined in terms of various microclimatic conditions related to temperature and air circulation in hot environments [18,19].…”

This study analyzed the environmental role of a flexible canopy as a microclimate modifier in balancing indoor energy demands and outdoor thermal comfort. Flexible building elements are often installed in traditional buildings, depending on the local climate in southern Europe. The architectural performance of a canopy was analyzed using several environmental software packages (Ecotect, Rayman, WinAir, DaySim, and EDSL TAS). Coupling methods were applied to determine the environmental influence of the attached building element, a canopy with fixed and operable panes in different orientations and locations. The results showed that the flexible canopy played a crucial role in reducing indoor energy demands (heating and electricity for lighting) and increasing outdoor thermal comfort under the canopy area. Outdoor thermally comfortable conditions ranging between 13 and 29 °C in the canopy space could be enhanced by 56.3% over the entire year by manipulating a flexible canopy, compared with a fixed canopy with 90% transparency in London. The flexible canopy with higher transparency helped increase outdoor thermal comfort in Glasgow, while one with lower transparency showed better performance during summer in London. The findings of this research will help broaden the range of architectural elements used in buildings.

“…Another essential aspect responsible for increasing building energy consumption is climate change, which occurs naturally or by human interventions [6]. These changes are attributed to change in meteorological variables (such as solar radiation, longwave radiation, air temperature, air humidity, air wind speed and direction, and their interactions [7][8][9]) prevailing over a large area (spatial), usually spanning over several years (temporal). The built environment alters the local meteorological variables and creates its unique local microclimate, which is significantly different from surrounding neighbourhoods [10,11].…”

A correct prediction of building cooling load is essential in building energy consumption in a hot and humid urban area. To this extent, the current study emphasizes a meticulous review of different convective heat transfer coefficient correlations including those developed considering neighbourhood microclimate effect, and the existing ones used in building energy simulation programs such as EnergyPlus, Environmental Systems Performance -Research (ESP-r), Integrated Environmental Solutions Ltd (IES), IDA, and TAS. Furthermore, rigorous quantitative assessment of associated convective thermal load from the windward, leeward, and roof surfaces under the case of microclimatic conditions is performed. The data used in the current assessment are computational fluid dynamics results, as a reference, from previously published data and actual weather data from the hot and humid climate. It is observed that very few convective heat transfer coefficient correlations show closer predicted thermal load (deviation less than 30%) with computational fluid dynamics results, and others exhibit a varying degree of prediction ability with over-predictions in general for the windward, leeward and roof surfaces. Current analysis suggests that further attention is required to increase the prediction ability of convective heat transfer coefficient correlations by developing a convective heat transfer coefficient model considering computational fluid dynamics analysis of the whole district, validating and modifying or redefining existing convective heat transfer coefficient correlations based on real field measurement data considering flow field around the building, and incorporation of urban morphology, vegetation, urban heat island, and urban pollution level in convective heat transfer coefficient correlations development.

“…Urban microclimate CFD software varies substantially depending on its physical basis, spatial-temporal resolution, and output variables (Allegrini, et al, 2015). The most widely used both nationally and internationally are Envi-MET met (Crank et al, 2018;Maggiotto, 2021), Energy-Plus (Kuo-Tsang & Yi-Jhen, 2017;Yang et al, 2012), SOLENE-Microclimate (Merlier et al, 2019;Morille et al, 2015), TRNSYS (Palme & Salvati, 2018;Perini et al, 2017), and SIMEDIF (Boutet et al, 2016;Ruiz & Correa, 2015), among others.…”

The Metropolitan Area of Mendoza (MMA), Argentina, has extended towards peripheral hillside areas without considering the environmental impact of this action. This growth has continued the urban model of flatland development, causing changes in the ecosystem and an increase in outdoor air temperature. This work proposes and evaluates urban schemes that incorporate design criteria with the objective of preserving environmental characteristics and mitigating the effect of urbanization on the microclimate. The proposed grid layouts, located in three predominant slopes, were linear organic and Cul-de-Sac. Methodologically, the microclimatic response of the proposed schemes was evaluated by applying ENVI-met software simulation. The results show that urban growth is possible when carefully considering environmental limitations which grant maximum air temperature reductions of up to 2 °C.
