WitrynaHeald, 1940). The importance of infiltration was demonstrated by the creation of the Air Infiltration Centre (AIC), which held its first conference in 1980 focusing on infiltration measurement (Air Infiltration Centre, 1980), and subsequently evolved into the Air Infiltration and Ventilation Centre (AIVC). WitrynaThe importance of infiltration combined with the difficulties in obtaining reliable data suggests that the field technician should expect to spend considerable time evaluating infiltration.
