A strategy for minimizing or avoiding the so-called stack effect within buildings ( 20 ) includes controlling the temperature within a vertically extending shaft ( 40 ) such as an elevator hoistway or stairwell. Controlling the air pressure at each of a plurality of levels (A, B, C, D) within the useable or occupied space of a building ( 20 ) allows for controlling a pressure differential between the useable or occupied space and an interior of the shaft ( 40 ). Maintaining appropriate pressure differential levels allows for minimizing or avoiding the stack effect that otherwise results in undesirably large drafts between the building interior and the outside, surrounding environment.
