Optimal Timing for Blower Door Tests
Determining the best time to conduct blower door tests depends on various factors, including weather conditions and the purpose of testing. Typically, testing is most effective during moderate weather when temperature and humidity levels are stable, allowing for accurate assessment of air leakage without external influences.
Perform blower door tests prior to seasonal weather shifts to establish baseline air leakage levels.
Ideal conditions are during spring or fall when temperatures are moderate, ensuring consistent results.
Testing immediately after construction or renovation ensures building envelope integrity is maintained.
Conduct tests before sealing or weatherproofing to accurately identify air leaks.
Equipment is calibrated and prepared for precise air leakage measurement.
Technicians seal the building and depressurize the space to identify leaks.
Data is collected and analyzed to determine air infiltration levels.
