Final answer:
The Construction Blower Door Service assesses a building's air tightness, identifying leaks and improving energy efficiency; it is usually undertaken during and/or after the construction process.
Step-by-step explanation:
The Construction Blower Door Service is an assessment used to measure the air tightness of buildings and identify areas where air leakage is occurring. This helps improve the energy efficiency of the building by ensuring that heating and cooling efforts are not wasted due to uncontrolled air infiltration, which can also lead to moisture problems. The purpose of this test is to:
- A) Test under construction conditions to identify leaks early and rectify them before construction is completed.
- B) Test after construction is complete to verify that the building meets required air tightness standards and to ensure that all leaks have been adequately sealed.
- C) Test only when requested by the builder, depending on the project requirements or specifications set by the builder or relevant codes.
- D) Do not perform blower door tests during construction is not a standard recommendation as testing can be beneficial during different construction stages.
In an educational context, designing an air flow diagram and testing hypotheses with tissue paper is a practical way to understand air movement and its effects on a room's environment, hence relating to the principles assessed by a blower door test.
