The space offered to a pedestrian is continually recomposed by orientation, canopy and air flow. Studying open urban fabrics in Barranquilla, Therán-Nieto and colleagues use two computer-simulation protocols to explore the effects of canyon geometry, building materials, tree cover, solar radiation and wind in a hot, dry tropical climate. Their simulations distinguish sharply among facades, ground planes, solstice dates and street orientations; favourable shade conditions can coexist with less favourable ventilation, and morphological parameters interact rather than operate as isolated variables. The operation is the controlled construction of alternative microclimatic situations, not the direct observation of a population's thermal comfort. Neither simulated radiation nor local wind speed can stand alone for a health effect. The study instead gives comparative walking research a demanding vocabulary of place: the same route requires timestamped orientation, surface and vegetation records before its climatic qualities can be interpreted or reproduced elsewhere.
