Owner-builders

Booking the test on a house you are building yourself

An owner-builder books directly with our office. No contractor has to place the booking, and the details are the ones a builder would send.

  • The address

    The street address of the new house.

  • The permit number

    The building permit for the house.

  • The ready date

    The day the last pipe, wire, vent and duct through the outer walls, ceiling and floor will be in place. On your own build, that means confirming with the plumber, the electrician and the heating and cooling installer that their last opening is made.

  • The site contact

    The name and number of the person who opens the house on test day. If you live out of town during the build, that can be your builder or someone local with a key.

  • Getting in

    Any gate code, lockbox or directions needed to reach the house and open it.

Custom plans

Custom features that move the measured boundary

The test measures the shell around the heated and cooled rooms. On a custom plan, the attic, the garage and the outdoor living areas decide where that shell runs, so mention them when you book.

  • An attic sealed at the roof deck

    The attic is opened to the house for the test and measured with it, roof deck and gable walls included.

  • A vented attic

    The attic sits outside the test, and the ceiling below it is the boundary.

  • An attached garage

    A garage that is not heated or cooled is outside the test. The wall and the door between it and the living area are part of the measured boundary.

  • A room over the garage

    When that room is heated and cooled and the garage below is not, the floor between them is part of the boundary too.

  • Sunrooms and enclosed porches

    One heated and cooled with the house is inside the shell. An open or screened porch is outside it.

  • Pools and outdoor kitchens

    They sit outside the test. Only a gas line, water line or wire that leaves the house to reach them makes an opening in the shell.

Setting the test date on a long custom build

A custom build can run long, and its ready date can move more than once. Book the test well ahead of the date you need the house finished, so the calendar has room for corrections and a second test if the first reading is over 7. Paint, flooring, trim, cabinets and countertops do not change the reading, which lets the test come before the finish work instead of after it.

When the ready date slips, call the office and a new test date is set. Put the booked date on the schedule your trades work from, so tile, trim and paint crews know the day the fan will be in the house.

Test day

How the house is left for the test

The code sets these conditions for the time the test runs. Wide sliding and folding glass doors count as exterior doors and are closed and latched with the rest.

  • Windows and exterior doors

    Closed, but not taped or sealed.

  • Fireplace and stove

    Their doors closed.

  • Dampers

    Exhaust, intake and flue dampers closed.

  • Interior doors

    Open, where they are installed.

  • Heating and cooling

    Turned off.

  • Registers

    Supply and return registers fully open, where they are installed.

What happens when the fan goes in

A fan is fitted in an exterior doorway, in a frame and panel that close off the rest of the opening. The fan moves air through the doorway until the house sits at the test pressure, and the amount of air it has to move to stay there is the leakage. The result is one reading for the whole house.

Testing a custom house before or after the drywall

A custom house can be tested before the drywall goes up or after. A test before drywall reads the shell as it stands that day, so whatever the plan relies on to stop air, whether sheathing, house wrap, sealed top plates or a sealed roof deck, has to be complete by then. A test after drywall reads the finished shell. On a custom build the builder picks the point, and the booking works the same way either way.

Trades working in the house on test day

On a custom build with trades still inside, work can continue during the test as long as the house stays in the test-day set-up and nobody uses the doorway holding the fan. Noise, dust and work on the lot next door have no effect on the reading. The person named as site contact is the one who keeps the house that way until the fan comes out.

Scope

What the reading leaves out

A blower door reading is about air leakage alone. Other parts of a custom house are covered by other sections of the energy code.

  • Insulation

    How much insulation is in the walls, floor and attic is not part of the reading.

  • Windows and glass doors

    Their energy ratings are set out elsewhere in the code.

  • Heating and cooling equipment

    The size and efficiency of the system are not measured by the fan.

The limit

The limit for a new Santa Rosa Beach house

Section R402.4.1.2 of the 2023 Florida Building Code, Energy Conservation, allows a new house no more than 7 air changes per hour at 50 pascals in Climate Zones 1 and 2. Table R301.1 places Walton County in Climate Zone 2.

  • At 7 or below

    The reading is within the limit.

  • The retest

    Run under the same conditions as the first test, so the two readings compare.

FAQ

Santa Rosa Beach blower door questions

Have another question? Call (850) 819-6031.

Does a bigger house get a looser limit?
No. The limit is 7 for any size of house. Size is already in the number, because the airflow the fan measures is divided by the volume of the house.
What does air changes per hour mean?
It is how many times the air inside the house would be replaced by outside air in one hour at the test pressure. It does not describe how long the test takes.
What does 50 pascals equal?
50 pascals is 0.2 inches of water gauge. The code gives both figures for the same test pressure.
Can the test happen before the driveway and landscaping are done?
Yes. Driveways, walks and planting beds are outside the house and have no effect on the reading.
Does the house need to be furnished?
No. Furniture sits inside the shell and does not change the reading.
Does a detached garage or pool house count?
No. A building standing apart from the house shares no wall with it and is not part of the test.
