To create a high-performing building, you have to know how air quality can affect your design. For example, will the building exhaust recirculate right back into the building, causing occupants to breathe unhealthy air? Will it contaminate the daycare center or operating room? Will exhaust affect the performance of equipment? Will the plume freeze on the façade?

Assessing and mitigating building air quality issues can be complex. Wind flow around buildings is the key. Exhaust travels with the wind, and wind is invisible. As a result, sometimes exhaust ends up where you least expect it, like at an air intake opposite the direction of the wind. Seemingly small design choices, such as architectural features or equipment placement, may have unexpectedly broad effects on wind flow patterns, either positive or negative. It takes a specialist eye to see the unseen and to bring practical solutions to this often complicated issue.
