Building Air Leakage Testing for Commercial Properties

Central Energy Audits provides commercial blower door testing to help identify air leakage, measure building airtightness, and support better energy performance for commercial and multifamily properties. A blower door test uses specialized diagnostic equipment to create a controlled pressure difference in the building, allowing air leakage issues to be measured and located more accurately.

Central Energy Audits is based in Kansas City, MO and serves clients throughout Kansas and Missouri. The company’s work focuses on energy audits, HERS ratings, blower door testing, duct testing, thermal imaging, HVAC load calculations, and energy performance documentation. Their website states that blower door testing is used to measure airtightness and identify air leaks that may affect comfort, efficiency, and performance.

​

What Is Commercial Blower Door Testing?

Commercial blower door testing is a diagnostic process used to evaluate how much uncontrolled air leakage exists in a building. During the test, calibrated blower door equipment is installed in an exterior opening. The equipment changes the pressure inside the building so that air movement through gaps, cracks, penetrations, doors, windows, and other leakage points can be measured.

The purpose of the test is to provide useful data about the building envelope. This helps building owners, contractors, developers, and project teams better understand how air is moving through the building.

A commercial blower door test may help identify leakage around:

​

• Exterior doors

• Windows

• Wall penetrations

• Roof and ceiling transitions

• Mechanical, electrical, and plumbing penetrations

• Utility openings

• Envelope connections

• Air barrier details

• Areas with visible drafts or comfort complaints

​

Central Energy Audits already uses blower door systems and infrared cameras as part of its diagnostic testing approach to locate leaks and thermal losses that may not be visible during a basic inspection.

​

Why Commercial Blower Door Testing Matters

Air leakage can affect building performance in several ways. When outside air enters or conditioned air escapes through uncontrolled leakage points, HVAC systems may have to work harder to maintain indoor temperatures. This can contribute to higher energy use, comfort issues, and inconsistent indoor conditions.

Blower door testing helps move the conversation from guesswork to measured data. Instead of relying only on visual inspection, the test provides information about the building’s airtightness and can help identify where air sealing may be needed.

The U.S. Department of Energy explains that blower door testing is used by energy professionals to determine how much air is entering or escaping a building and to identify areas of air leakage. The test can also help with energy-saving improvements, HVAC sizing considerations, and determining whether ventilation needs should be evaluated.

​

When a Commercial Blower Door Test May Be Needed

Commercial blower door testing may be useful for several types of projects, including new construction, renovations, energy performance evaluations, building envelope troubleshooting, and projects where documentation is needed for code, certification, or owner requirements.

A test may be helpful when a building is experiencing:

​

• High heating or cooling costs

• Drafts or comfort complaints

• Uneven indoor temperatures

• Suspected air leakage

• Recent air sealing or envelope improvements

• Renovation or retrofit planning

• Energy efficiency concerns

• Building performance documentation needs

​​

For project teams, blower door testing can also provide verification after air sealing or envelope work has been completed. This helps confirm whether improvements made a measurable difference.

​

A Data-Based Approach to Building Performance

Central Energy Audits focuses on testing, inspection, and documentation. Their energy audit process includes blower door testing, infrared thermal imaging, duct leakage testing, attic and crawl space inspection, HVAC review, and written reporting with recommendations.

For commercial buildings, this same data-based approach can help project teams better understand how the building envelope is performing. Air leakage is not always visible. A building may look complete from the outside while still having hidden gaps, unsealed penetrations, or areas where conditioned air is escaping.

Commercial blower door testing helps identify these issues so that the next steps can be based on actual test results.

​

Commercial Blower Door Testing and Energy Efficiency

A tighter, better-performing building envelope can support improved energy efficiency and indoor comfort. While blower door testing itself does not fix air leakage, it provides the information needed to make targeted improvements.

The test can help building owners and contractors avoid random air sealing by showing where the biggest leakage concerns may be located. This allows the project team to prioritize improvements more effectively.

For commercial properties, this can be especially important because air leakage may affect larger spaces, multiple rooms, shared walls, mechanical systems, and building-wide energy performance.

​

Blower Door Testing With Thermal Imaging

Central Energy Audits uses advanced diagnostic tools such as blower door testing and infrared thermal imaging to help identify leaks, poor insulation, HVAC inefficiencies, and other building performance concerns.

Thermal imaging may help locate temperature differences in walls, ceilings, floors, windows, and other areas of the building. When used with blower door testing, it can provide additional visual evidence of where leakage or thermal loss may be occurring.

This combination can be helpful for buildings where comfort complaints, energy loss, or envelope problems are not obvious during a standard walkthrough.
