What distinguishes multi-point testing from single-point testing?

• A. Number of pressure points measured
• B. Type of equipment used
• C. Time taken for testing
• D. Number of personnel needed

Answer: (A)

The distinction between multi-point testing and single-point testing primarily lies in the number of pressure points measured during the testing process. Multi-point testing involves taking measurements at various pressure points throughout the building or area being tested. This approach allows for a more comprehensive assessment of the airtightness of a structure, as it can identify variations in air leakage that may occur due to different conditions within the space. In contrast, single-point testing focuses on measuring airtightness at just one specific point, which offers a limited view and may not accurately reflect overall building performance. By utilizing multiple pressure points, multi-point testing provides a more detailed and reliable understanding of how air moves through a building envelope, enhancing the quality of the testing results and the subsequent decisions made regarding building performance and improvements.
