Assessing Air Tightness

A blower door test is a highly effective way to measure the air tightness of your home. Furthermore, by using a powerful fan to depressurize the house to 50 pascals, equivalent to a 20 mph wind on all sides of the residence, our experts can determine areas where air leakage occurs. Investing in blower door testing can help you identify and address areas of energy loss, leading to lower energy bills and increased comfort.

Understanding the Results of a Blower Door Test

Understanding the results of a blower door test is essential for identifying areas where air leakage is occurring and for making improvements to enhance a building’s energy performance and comfort.Blower door test results revealed the building’s air infiltration rates to be within acceptable limits, indicating effective sealing and insulation. These findings underscore the structure’s energy efficiency and adherence to performance standards. The auditor makes some various calculations from the blower door test in order to give you the results. Below are some terms that the auditor may speak to when referring to the results of a blower door test:

This refers to Air Changes Per Hour at the 50 pascals. The system will replace the total volume of air in your home 5 times every hour. The lower the number the tighter the exterior envelope of the house is. It is important to note that anything at 2 ACH at 50 and below requires fresh exchange from your HVAC system for health and safety reasons.

This refers to cubic feet per minute at 50 pascals. It helps the auditor/homeowner understand how much air is moving from the house to the outside. The results of this number are helped to calculate ACH at 50. A tighter sealed envelope is usually under 1250 CFM at 50 and anything above 2500 would be considered a very leaky home.

The blower door test helps identify areas of concern and guides the selection of appropriate measures to address them. Additionally, it can contribute to cost savings through reduced energy consumption and improved building performance.

  • Building codes and energy efficiency standards often specify target ACH50 or CFM50 values that buildings should achieve. These targets vary by region and type of construction.
  • Technicians may also use smoke sticks or infrared cameras to visualize airflow and pinpoint the location of leaks.The test results are typically compared to these target values to assess whether the building meets energy efficiency or airtightness requirements.
  • During the blower door test, technicians may perform visual inspections and use thermal imaging cameras to identify areas of significant air leakage, such as gaps, cracks, or improperly sealed openings.
  • Technicians may also use smoke sticks or infrared cameras to visualize airflow and pinpoint the location of leaks.It is also important to test out your home after any air sealing improvements have been made for health and safety reasons. Schedule a test or energy audit today!
