1. Which of the following is the primary purpose of an energy code
inspection during building construction?
A. To verify architectural aesthetics only
B. To ensure compliance with adopted energy conservation requirements
C. To determine property tax assessments
D. To evaluate the market value of the building
B. To ensure compliance with adopted energy conservation requirements
Rationale: Energy code inspections verify that buildings comply with
applicable energy conservation codes by ensuring proper installation of
insulation, air barriers, HVAC systems, lighting, and other energy-related
components, thereby improving energy efficiency and reducing operating
costs.
2. Which building component has the greatest influence on thermal
performance of the building envelope?
,A. Landscaping
B. Building envelope insulation and air barrier system
C. Interior paint color
D. Furniture arrangement
B. Building envelope insulation and air barrier system
Rationale: The building envelope, including insulation and air barriers,
controls heat transfer and air leakage, making it the most significant factor
affecting building energy efficiency.
3. An Energy Code Inspector should primarily verify that installed
materials match:
A. Manufacturer advertising brochures
B. Contractor preferences
C. Approved construction documents and applicable energy code
requirements
D. Homeowner recommendations
C. Approved construction documents and applicable energy code
requirements
Rationale: Inspection focuses on ensuring that installed systems conform
to approved plans and adopted code requirements rather than personal
preferences or promotional materials.
4. Continuous insulation is primarily intended to:
A. Increase structural strength
B. Reduce thermal bridging
C. Improve sound transmission
D. Support roofing materials
B. Reduce thermal bridging
,Rationale: Continuous insulation minimizes heat flow through framing
members by providing uninterrupted insulation across the building
envelope, significantly improving energy performance.
5. Thermal bridging occurs when:
A. Air conditioning equipment is oversized
B. Heat flows through highly conductive building materials
C. Windows are cleaned frequently
D. Plumbing pipes are insulated
B. Heat flows through highly conductive building materials
Rationale: Thermal bridges occur where conductive materials bypass
insulation, allowing heat to transfer more readily and reducing overall
energy efficiency.
6. The purpose of an air barrier is to:
A. Support roof loads
B. Prevent uncontrolled air leakage through the building envelope
C. Replace insulation
D. Improve acoustics only
B. Prevent uncontrolled air leakage through the building envelope
Rationale: Air barriers limit unintended airflow through the building
enclosure, reducing energy loss, moisture migration, and occupant
discomfort.
7. Which test is commonly used to measure building air leakage?
A. Slump test
B. Blower door test
C. Compression test
D. Rebound hammer test
, B. Blower door test
Rationale: A blower door test depressurizes or pressurizes a building to
measure air leakage and evaluate envelope tightness required by many
energy codes.
8. The R-value of insulation measures:
A. Fire resistance
B. Structural capacity
C. Resistance to heat flow
D. Water absorption
C. Resistance to heat flow
Rationale: Higher R-values indicate greater resistance to conductive heat
transfer and improved insulating performance.
9. The U-factor of a building assembly represents:
A. Air leakage rate
B. Overall heat transfer rate
C. Solar reflectance
D. Moisture permeability
B. Overall heat transfer rate
Rationale: Lower U-factors indicate better thermal performance because
less heat passes through the assembly.
10. Vapor retarders are primarily installed to:
A. Increase roof drainage
B. Control moisture diffusion through building assemblies
C. Improve sound insulation
D. Increase daylighting
B. Control moisture diffusion through building assemblies
