What is a blower door test? Effective July 1, 2017 - The Fifth Edition of the Florida Building Code (FBC) requires blower door testing for all residential dwelling units. This would include single family houses, town houses, duplexes, and each condominium and apartment unit where the building is three stories or less.The smoke pen is a simple test tool used to pinpoint air leaks. It has a wick that is lit on fire with a lighter or match. Once the wick has burned for a few seconds, you blow out the flame and allow the wick to smoke. The smoke lasts only a few minutes; when the the pen stops smoking, you will have to re-light the wick. Minneapolis Blower Doors (5) Oakton (1) PCE Instruments Your Price: $645.00.

Most people pay around $250 for a level 2 energy audit on a 1,200 sq.ft. home, including a blower test. At the low end of the spectrum is a level 1 energy audit on an 800 sq.ft. home for $80. At the high end is a level-3 energy audit on a 2,600 sq.ft. home using advanced tools and methods for $1,500.
Q = CΔP n. Q is the flow (cubic feet per minute), C is a constant, P is pressure, and n is the exponent of the power law equation. The exponent can vary between 0.5 and 1.0, with essentially big holes in the building making an exponent of 0.5 the best fit (curved line) and very tiny holes making the exponent of 1 the best fit (a straight line).Sections R402.4.1.2 and R104.5 indicate that a Florida blower door test must be done by an approved third party Energy Auditor or Energy Rater . Both titles require certification – either from the Building Performance Institute (BPI) or Residential Energy Services Network (RESNET) – to qualify.
