What is the purpose of a blower door test?
Answer: Detect air infiltration
A blower door test measures air leakage in a home to evaluate airtightness and identify areas needing sealing.
Which tool is commonly used to detect insulation gaps?
Answer: Thermal camera
Thermal imaging cameras help inspectors identify missing or poorly installed insulation by revealing heat patterns.
What is a duct leakage test used for?
Answer: Determine duct system airtightness
A duct leakage test identifies leaks in a duct system to assess efficiency and improve HVAC performance.
Why is visual inspection important in the HERS rating process?
Answer: Confirm insulation and sealing quality
Visual inspection confirms that construction and installation details meet energy efficiency standards.
When should field inspections be conducted in new construction?
Answer: At rough-in and final stages
Field inspections are typically conducted at rough-in and final stages to verify installation practices and energy features.
Which measurement is commonly recorded during a blower door test?
Answer: CFM50 air leakage
CFM50 (cubic feet per minute at 50 Pascals) is the standard measurement used to evaluate air leakage.
