Airtightness tests for residential homes and commercial buildings

Whether in a residential home or a commercial building, controlling air leakage is the most important retrofit strategy when addressing energy efficiency. Controlling air leakage is simply an essential element in managing air movement and air moisture throughout a building envelope. While much focus is placed on air sealing and energy efficiency in high-rise buildings, these are equally important in a residential home environment.

The idea behind air leakage control is to systematically identify leakage, and comprehensively seal as many leakage paths as possible. Industry wide, professionals are endlessly pushing the concept of effective air sealing. And while cursory weather-stripping and weatherization techniques might be helpful, nothing compares with a professional approach to air sealing (from those who have experience and expertise).

Professionals simply do a better job – they accurately locate air leakage in a building envelope, and effectively retrofit to correct the compromises. They perform a professional blower door test, use advanced infrared scanners, and can isolate the source and full scope of air leakage. Controlling air leakage, in a home or building, is integral to maximizing energy efficiency. More than that, it’s a matter of managing indoor moisture levels and general air circulation. Finally, controlling air movement will have a direct effect on the HVAC system (heating and cooling).

Air Leakage Is Detrimental To Energy Efficiency

While air leakage can account for 25-30% of energy waste when heating and cooling a building, corrective measures can turn the equation around into substantial dollar savings. In a residential home, it means effectively sealing the roof, attic, basement, and any other air leaks. Similarly, in a building, comprehensive air sealing will create dramatic improvement in energy efficiencies. For professionals, air sealing retrofits represent the very best return-on-investment.

To begin with, there are substantial heating and cooling savings that derive from a well-sealed building. Season after season, the savings mount up, and in many scenarios the cost of retrofitting can be “paid down” by the substantial annual savings. Home or building, it makes economic sense.

Airtightness Tests From Barrier Sciences Group

As accredited energy auditors, Barrier Sciences Group uses a blower door test to determine a building’s airtightness. Essentially, the airtightness test measures “Air Changes Per Hour” - in other words, how much indoor air volume is changing every hour. It may not be noticeable, but indoor air moves quite a bit – and constantly. Measuring this air movement (ACH) will reveal how much air infiltration or exfiltration is happening throughout the building envelope.

The team at Barrier Sciences Group provides comprehensive air tightness testing, with objective reporting, and viable retrofit proposals. Whether it’s residential, commercial, or institutional, BSG tests for air leakage with some of the most advanced diagnostic tools available. Homeowners and building owners are therefore equipped to make astute decisions on repairs, retrofits, and renovations going forward. The bottom line, of course, is to improve energy efficiency.
