Whole Building Air Tightness Testing. Air tightness testing is a process in which the building envelope is tested to quantify the air tightness. The test measures air leakage rates through a building envelope under controlled pressurization and depressurization. Air leakage of the envelope can be a quantitative value which can affect the .
What is a blower door test? Blower door tests are becoming part of many State and Provincial mandatory building codes - the new BC Energy Step Code in British Columbia, Canada is one example. A blower door test is often an essential part of a home audit, we don’t know for sure just yet if it will be part of the free home energy audits promised by the Canadian .

Given this, improving your home’s air sealing can be an extremely cost-effective approach for reducing energy consumption, carbon emissions and energy bills! Our Blower Door Air Tightness Testing process will locate all major areas of natural air infiltration in your home and provide strategies for remediation.1.2 Testing procedures of watertight compartments for SOLAS Ships (including CSR BC & OT) are to be carried out in accordance with PART A, unless: . A test to verify tightness by means of air pressure differential and leak indicating solution. It includes tank air test and joint air tests, such as compressed air fillet weld tests and .
Air Testing – also known as Air Tightness Testing, Air Permeability Testing, Air Leakage Testing, and Air Pressure Testing – measures the amount of air escaping through cracks and gaps in the building envelope. A more airtight building translates to better energy efficiency, lower heating and cooling costs, and a more comfortable living .
The below table summarizes maximum air leakage rates and testing standards across British Columbia for different Building types, Code requirements, Home Labeling, or Certification programs. Click HERE to read the full bulletin from BC Housing “Building Airtightness Targets in Code and Standards Across BC: Appendix A“Test air tightness at completion; Quantify mechanical efficiency and heating needs; As shown below, the regulation sets performance targets for new construction and groups them into “steps” that apply across various building types and regions of the province. The Lower Steps are relatively straightforward to meet; the Upper Steps are more .The building’s air leakage rate is quantified by testing. The most common air tightness test is typically referred to as a “blower door” test (page 2). The test equipment consists of a calibrated fan, a panel to seal off the door, and a flow and pressure .
A mid-construction blower door test is a diagnostic test which depressurizes or pressurizes the home to identify unintentional leaks and issues with the air barrier. Importantly, the mid-construction blower door test needs to be scheduled at a point in the construction when it is not too late to effectively remedy identified air leakage issues. A Air Tightness Metrics. Beyond energy performance, airtightness is another crucial aspect of the BC Energy Step Code. It introduces additional airtightness testing metrics, known as NLR (Normalized Leakage Ratio) and NLA (Normalized Leakage Area). Applicable to both Part 9 and Part 3 buildings, this webinar will discuss diagnostic methods in detail, such as infrared thermography and smoke tracer testing, and use them to compile an air leakage inventory. Presenters will share remediation methods and show how following a particular order of operations can prevent the need for repairs. Concepts [.]
AIR TIGHTNESS SOLVED Island AeroBarrier utilizes innovative and award-winning technologies to stop air leaks in commercial and residential building envelopes and ducting. Sealing is accomplished by pressurizing the enclosure with a fan while creating a fog of sealant. The air that is escaping through all of the undesired holes carries the . The paper designs an air tightness test system of electric pneumatic valves based on differential pressure method using MSP430 as controlling core and proves that this system can realize quantitative description based on qualitative description for testing leakage rate.
