! Extensive experimental program ! Perfluorocarbon tracer (PFT)
testing to measure airflows
! Long term monitoring of pressure differences
! Pressure neutralized airtightness testing
Case Study Building
! Very interesting measured results regarding: ! Pressurized corridor ventilation systems
! Interaction of driving forces (wind, stack effect, & mechanical)
! Airtightness and compartmentalization
