Final answer:
The correct procedure for a blower door test under windy conditions is to seal exterior openings. Students use diagrams and tissue paper to record and analyze airflow, updating their hypotheses with experimental evidence.
Step-by-step explanation:
When undertaking a blower door test under windy conditions, the correct troubleshooting procedure would be to seal exterior openings. This step helps to minimize the effect of wind on the test results, ensuring that the measurement of the building's air tightness is as accurate as possible. During the experiment, students are expected to hypothesize and record air flow using diagrams and physical tests involving tissue paper. They will modify their hypothesis based on evidence collected during the experiment, which involves analyzing the direction of airflow in relation to open windows or doors and recording this on their diagrams for further discussion and correction based on the experimental data and any limitations noted.
