air leakage

Infiltration and ventilation in Russian multi-family buildings.

Equivalent leakage areas (ELAs) of 50 Russian apartments were measured under three conditions: 1) as found, 2) exhaust vents sealed, and 3) vents, electric boxes and windows sealed, in 12 buildings of similar construction. Distributions of ELA per unit of apartment volume are presented for the three conditions. Apartment ELAs were found to vary slightly with floor, indicating that the level of occupant-applied weatherstripping is a function of occupants' perception of infiltration rates and that lower floor occupants perceive larger infiltration rates than upper floor occupants.
