In a study of the energy consumption of apartment buildings, conducted under contract for the Division of Building Research, the possible effects of infiltration were given close scrutiny, since there seemed to be some major differences between these buildings and similar ones with other occupancies. This field study was aimed at establishing whether these differences existed in practice, and in particular if stack effect causes significant variations in the heating requirements of apartment units according to their location in tall buildings. Indications are that stack effect is suppressed in tall apartment buildings when supply and exhaust fans are running, and that the corresponding effect on heating consumption is weak or negligible depending on building height.
