Wind

A building changes the wind around it. Tall volumes catch faster air from above and push it down their faces to the street. Corners speed it up, and a gap between two towers can turn a breeze into a draught. The people who feel it are the ones on the pavement, at the entrance, or sitting in the square the plan was meant to give them.

These effects come from the massing: height, spacing, orientation, and whether a tower meets the ground directly or sits on a podium. That is why wind belongs in the earliest design stage, when moving a volume is still easy.

Canvas evaluates wind alongside its solar and micromobility studies, on the same model as every other lens. When the massing changes, the effect on comfort at ground level around the new volumes shows up with it, so an option that works for capacity but not for the street is caught before it goes further.
