Final Performance Assessment
The builder/owner must be present for the walk-through final inspection. An air infiltration analysis (blower door) and infrared thermal scan will be completed to determine the overall air-tightness or infiltration rate of the home, and to check insulation levels and quality of installation. The results of the blower door analysis will help the builder/owner identify any areas of air leakage requiring remedial action.
The builder and his/her subcontractors must insure the ventilation system meets minimum air change standards and that there is sufficient makeup air in the home to prevent negative pressure.
