How Blower Door Airtightness Testing Works
Blower Door Airtightness Testing is a crucial process for assessing and improving the air tightness of residential properties. During a Blower Door Airtightness Test, a large industrial fan is set up in an exterior door of the home to create negative pressure or a vacuum effect. This depressurization process allows experts to identify air leakage points such as doors, windows, attic hatches, wiring, and more. By conducting this test, professionals can determine the air changes per hour (ACH) in a building, which is a key metric for assessing its airtightness level.
Why Blower Door Testing Matters
Blower Door Testing is a vital component of energy efficiency assessments, allowing our experts at Monolith Housing Solutions to measure the air leakage in a home and identify areas where energy is being wasted. By conducting a Blower Door Test, we can determine the air changes per hour (ACH) in a building, assess its airtightness level, and pinpoint areas of concern that may compromise energy efficiency.
Mid-Construction Blower Door Test: Ensuring Quality Throughout the Build Process
Building Experts
Mid-construction blower door tests are frequently performed by outside experts, which builders, contractors, and construction project managers employ. Specialized tools, such a blower door fan, pressure gauges, and other instrumentation, must be used during the testing procedure and must be operated by qualified specialists. Accurately determining the building’s airtightness is the goal.
Mid-construction blower door testing should be performed by qualified experts to assist guarantee the accuracy and dependability of the findings. These professionals are capable of analyzing the data, pointing out problem areas, and making suggestions for enhancing the building’s airtightness and energy efficiency. Efficient and sustainable building methods are implemented more successfully when construction teams work together with knowledgeable experts during mid-construction blower door testing.

Benefits of Blower Door Airtightness Testing
Energy Savings By improving a home’s airtightness, homeowners can reduce energy consumption, lower utility bills, and minimize their environmental impact, aligning with CleanBC’s initiatives to promote sustainable living. Comfort Enhanced airtightness leads to improved indoor air quality, temperature consistency, and overall comfort for residents. Durability Airtight homes are less prone to moisture damage, mold growth, and structural issues, ensuring long-term durability and sustainability. Compliance Our testing services help homeowners meet energy efficiency standards, building codes, and eligibility requirements for incentives such as BC Hydro rebates plans, which support energy-efficient upgrades and sustainable living practices.Partner with Monolith Housing Solutions for Energy Efficiency Excellence

What the Test May Include
These could be included in a mid-construction blower door test service:
- Measurements needed to compute area and volume.
- Utilizing a blower door fan to conduct the airtightness test.
- Identifying and recording the air leaks: when the house is pressurized or depressurized, air can be felt slipping in through inadvertent openings in the building envelope.
- Utilizing HOT2000 or alternative software to calculate preliminary blower door metrics.
- Air changes hourly (ACH) or alternatively.
- NLA, or normalized leakage area, and/or
- Leakage rate normalized (NLR).
The energy adviser is present at the location with the blower door while a team performs air sealing, a process known as “blower door guided air sealing.” This enables the builder to gain from the energy advisor’s experience and the assurance that the air leakage objective is met. - Supplying a proper blower door test report (along with a story and pictures of the spots where air leaks).
- Additional duties that the two parties decided upon (such as retaking the test to look for improvements).
BENEFITS OF MID-CONSTRUCTION BLOWER DOOR TEST
A mid-construction blower door test helps your company avoid surprises and helps you to meet energy efficiency targets early in the process.
A home built with minimal levels of air leakage (and right ventilation) can reduce heat loss and energy bills in the winter, keep the home cooler in the summer, improve home comfort, enhance air quality, protect the building structure and other materials from moisture damage, and help prevent dust, noise, and insects from entering from outdoors.
A well-built and air sealed home can also shrink the environmental footprint of the home by reducing the greenhouse gas emissions produced by using energy to heat and cool your home.
The cost of addressing air leakage issues at the right time in the construction process can be negligible. If you wait until construction has been completed to identify air leakage issues, fixing the problem may be time consuming, expensive, or nearly impossible.
The mid-construction blower door test can be a practical teaching tool for your crews and sub trades. Involve them in the process: the test can be an opportunity for them to learn how to identify and address air leakage issues many builders have called the mid-construction blower door test more educational than weekend-long workshops on air tightness.
