Blower door testing is an essential part of ensuring energy efficiency, indoor air quality, and overall building performance in commercial structures. As buildings become more complex and energy standards more stringent, the demand for accurate testing and inspections has increased. This blog explores the best practices for blower door testing in commercial buildings, highlighting methods, preparation steps, and key considerations for achieving precise results. References are taken from industry standards and practices such as those outlined by Cornerstone Middle East. Understanding Blower Door Testing Blower door testing is a diagnostic method used to measure the airtightness of a building. In commercial buildings, uncontrolled air leakage can lead to higher energy costs, uneven indoor temperatures, and reduced comfort for occupants. The test involves using a powerful fan mounted in a temporary frame within an exterior doorway. This fan either pressurizes or depressurizes the build...
