Blown Away by Blower Door Testing.

1 Blower Door IMG_0295 700x420The humble Blower Door Test is one of the lynchpins of modern home energy assessments and analysis. And, if we may be so bold, probably a piece of testing equipment you’ve never heard of nor knew you needed! Let us explain, so, as homeowners, you have the knowledge and resources necessary to make the best buying decisions.

Air leakage can increase heating and cooling costs by over 30% and contribute to comfort, health, and safety issues, according to Energy Upgrade California experts. As a professional Home Energy Auditor and Advanced Home Energy Upgrade Specialist, Beckner Energy Upgraders uses blower door testing to help determine your home’s airtightness.

Reasons for improving building airtightness:

  • Reduces energy consumption due to home air leakage
  • Avoids moisture condensation problems
  • Mitigates uncomfortable drafts caused by cold air leaking in from the outdoors
  • Determines how much mechanical ventilation is needed for acceptable indoor air quality

HOW THE BLOWER DOOR TEST WORKS
A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside; higher outside air pressure then flows in through all unsealed cracks and openings. Allowing us to accurately track and measure results.

This test determines the air infiltration rate. It’s one of the most important assessment procedures to identify home energy consumption and pinpoint energy efficient measures to take. Problem areas, when corrected, can save you a significant amount of money longterm.
