Urban environments are characterized by a diversity of microclimates. To manage this complexity, assessments generally involve a certain kind of simplification: either an areal constriction (e.g. the analysis of distinct urban squares), or a spatial reduction (e.g. the reliance on the urban canyon model). This paper approaches the task at the scale of the urban block. In the analysis of metropolitan urban block typologies, the study adopts Probáld's concept of microclimate assemblages. With the presented approach, the research aims to compliment existing urban microclimate assessments. Utilizing the numerical modelENVI‐met, this paper focuses on the effect of building configurations.
