Landscaping, entrance canopies, and the Bow's curved shape help shield pedestrians on the southern entrance plaza from strong winds.
In winter conditions, the heated, used air from offices discharges into the atrium. The return air rises and runs through a heat exchanger with a heat-recovery unit, preconditioning the incoming fresh air.
In summer conditions, the cool, used air spills into the atrium where it is warmed by solar radiation. The air rises to the top and runs through a heat-recovery unit, which partially pre-dehumidifies the incoming air.
