Why Façade Testing?
Last chance for correction of design to meet performance.
Key to stability certification to the building.
Must for every building validation and certification.
Must for safety as a whole.

Weather - AIR LEAKAGE
Air Infiltration
-Under positive pressure
-Air infiltration means heat entering inside.
Air Exfiltration
-Under negative pressure
-Air exfiltration means loss of cool air.
Either way is loss of air-conditioning
Also loss in Acoustical performance.
Cannot be verified in drawings alone.
