Which type of testing is usually executed in the depressurization direction on smaller buildings?

• A. Multi-point testing
• B. Repeated single-point testing
• C. Two-point testing
• D. Continuous flow testing

Answer: (B)

The testing that is typically executed in the depressurization direction on smaller buildings is repeated single-point testing. This method involves depressurizing the building and then measuring the air leakage at a single point to assess the overall airtightness. This approach is particularly useful for smaller buildings because it requires less elaborate setup compared to other techniques, making it more efficient in terms of time and resources. Repeated single-point testing allows for quick assessments and is practical when dealing with smaller structures where one may want to quickly identify areas of significant air leakage without the need for a comprehensive multi-point or continuous flow analysis. In contrast, multi-point testing and two-point testing usually involve more complex setups and may require significant time to execute, making them less practical for smaller buildings. Continuous flow testing, while useful for certain applications, also tends to be more suited for larger buildings or specific conditions rather than the straightforward approach needed for smaller structures.
