Blower Door Testing

At HERS Rating Specialist, we provide professional blower door testing services to measure the airtightness of your building and ensure it meets energy efficiency and code compliance standards. This critical test identifies air leaks, helping improve energy performance, occupant comfort, and overall sustainability.

What is Blower Door Testing?

Blower door testing involves using a powerful fan mounted in an exterior door frame to depressurize the building. This process measures how much air is leaking through gaps, cracks, and other unsealed areas in the building envelope.

Why is Blower Door Testing Important?

  1. Energy Code Compliance: Required for meeting Massachusetts energy codes, including the 2018 IECC and Stretch Code.
  2. Increased Energy Efficiency: Detects and quantifies air leaks, reducing energy waste and lowering utility costs.
  3. Improved Indoor Comfort: Seals drafts and maintains consistent indoor temperatures.
  4. Enhanced Air Quality: Reduces the infiltration of outdoor pollutants and allergens.

 

Our Blower Door Testing Process

We follow a detailed approach to ensure accurate results and actionable insights:

1. Preparation

  • Seal all intentional openings, such as vents and dampers.
  • Close windows and interior doors to isolate the testing area.

2. Testing Setup

  • Install a blower door frame and fan in an exterior doorway.
  • Use precision gauges to measure air pressure changes.

3. Conducting the Test

  • Depressurize the building and monitor air leakage.
  • Identify specific areas with high leakage using diagnostic tools like smoke pencils or infrared cameras.

4. Reporting & Recommendations

  • Provide a detailed report of air leakage rates.
  • Offer tailored recommendations for air sealing and energy-saving improvements.

 

Who Needs Blower Door Testing?

  • Homeowners: To identify and address drafts, improving energy efficiency.
  • Builders: To meet energy code requirements and avoid costly delays.
  • Developers: To ensure large-scale projects comply with energy standards.
