The boundary
Attics and garages in a Grand Ridge test
Vented attic over the rooms
Stays outside. The ceiling drywall and everything cut through it form the line the fan reads.
Insulation at the roof deck
An attic sealed and insulated at the roof deck is opened to the house for the test, and its space is measured with the rooms.
Unconditioned attached garage
Stays outside. The shared wall and the door into the house are part of the measured boundary.
A room over the garage
Inside the test once it is heated and cooled, and its floor over the garage becomes part of the boundary.

Test day
Test-day set-up
Windows and outside doors
Shut and latched, not taped.
Fans, the hood and the dryer
Kitchen and bath fans off with their dampers closed, and the dryer not running, with its vent flap shut.
Fireplaces and stoves
Doors shut and flue damper closed.
Interior doors
Open throughout, bedrooms and closets included, so the whole house sits at one pressure.
Heating and cooling
Off for the test, with every supply and return register open.
Drain traps
Filled in any bath or kitchen that has not been used yet.
