“…The building area size significantly affects the UHI effect [ 234 , 235 , 236 ], both during the day and at night [ 153 ]. Increasing the building area leads to an increase in LST [ 237 ] and extends the duration of high air temperature.…”

“…In a narrow canyon, orientation is not correlated or is slightly correlated with canyon air temperature, both in summer and winter [ 132 ]. However, it contributes to lower wind speeds [ 235 ], which positively concerns PET in the winter [ 132 ]. In addition, increasing the direction variation in the narrow street may result in less radiation infiltration into the canyon, irrespective of the street main direction [ 256 ].…”

“…The increase of built-up areas’ volume and density can reduce the wind speed and the convective heat transfer. That increases the thermal mass, thus having a more substantial impact on the radial energy absorption and lower SVF leading to the thermal trap effect [ 235 , 241 ]. That leads to the growth of wall, street, and air temperatures in canyons and causes the nighttime UHI [ 227 , 241 ].…”

“…It depends on the growing season during a year, too. In addition to shade patterns, the density of the vegetation models the airflow [ 235 , 314 ]. Increasing the greenery density within a green area reduces not only the daily LST [ 171 , 172 ] but also the wind speed [ 235 , 314 ] and the convective cooling effect.…”

The urban heat island (UHI) effect is the main problem regarding a city’s climate. It is the main adverse effect of urbanization and negatively affects human thermal comfort levels as defined by physiological equivalent temperature (PET) in the urban environment. Blue and green infrastructure (BGI) solutions may mitigate the UHI effect. First, however, it is necessary to understand the problem from the degrading side. The subject of this review is to identify the most essential geometrical, morphological, and topographical parameters of the urbanized environment (UE) and to understand the synergistic relationships between city and nature. A four-stage normative procedure was used, appropriate for systematic reviews of the UHI. First, one climate zone (temperate climate zone C) was limited to unify the design guidelines. As a result of delimitation, 313 scientific articles were obtained (546 rejected). Second, the canonical correlation analysis (CCA) was performed for the obtained data. Finally, our research showed the parameters of the UE facilities, which are necessary to mitigate the UHI effect. Those are building density and urban surface albedo for neighborhood cluster (NH), and distance from the city center, aspect ratio, ground surface albedo, and street orientation for street canyon (SC), as well as building height, material albedo, and building orientation for the building structure (BU). The developed guidelines can form the basis for microclimate design in a temperate climate. The data obtained from the statistical analysis will be used to create the blue-green infrastructure (BGI) dynamic modeling algorithm, which is the main focus of the future series of articles.
