COMMON EXAM FREQUENTLY TESTED
QUESTIONS AND ANSWERS IN DETAILS 100%
VERIFIED EXAM HIGHLY RECOMMENDABLE
FOR GRADE A+
1. A client requests a conceptual residential design that maximizes passive
solar gain. Which orientation is most appropriate for the main glazing?
A. North-facing
B. South-facing
C. East-facing
D. West-facing
Correct Answer: B. South-facing ✓
Explanation: South-facing glazing maximizes winter solar gain and allows
shading control in summer, making it optimal for passive solar design.
2. Which document typically outlines the scope of work, responsibilities, and
compensation for a building designer?
A. Bill of quantities
B. Construction schedule
C. Design contract
D. Zoning ordinance
Correct Answer: C. Design contract ✓

3. In residential construction, what does “R-value” measure?
A. Structural strength
B. Thermal resistance
C. Moisture content
D. Air infiltration
Correct Answer: B. Thermal resistance ✓
Explanation: R-value indicates how well a material resists heat flow; higher
values mean better insulation.
4. A setback requirement primarily affects which aspect of site design?
A. Building height
B. Distance from property lines
C. Roof slope
D. Interior layout
Correct Answer: B. Distance from property lines ✓

A. Load-bearing walls throughout
B. Post-and-beam construction
C. Masonry partition walls
D. Balloon framing only

codes?
A. 6 feet
B. 6 feet 8 inches
C. 7 feet
D. 8 feet
Correct Answer: C. 7 feet ✓
