AICM Certified Green Built Environment
Specialist CGBES Exam
**Question 1. Which of the following best defines the “triple bottom line” in sustainability?**
A) Economic profit only
B) Environmental protection, social equity, and economic viability
C) Energy efficiency and waste reduction
D) Green certification compliance
Answer: B
Explanation: The triple bottom line expands success measurement to environmental, social, and
economic dimensions.
**Question 2. What is the primary source of a building’s operational carbon footprint?**
A) Embodied carbon in materials
B) Transportation of occupants
C) Energy used for heating, cooling, lighting, and equipment
D) Construction waste disposal
Answer: C
Explanation: Operational carbon arises from the energy consumed during the building’s use
phase.
**Question 3. In a cradle‑to‑grave Life Cycle Assessment, which stage is NOT included?**
A) Raw material extraction
B) Manufacturing
C) End‑of‑life disposal
D) Re‑manufacturing of reclaimed material
Answer: D
Explanation: Cradle‑to‑grave LCA stops at disposal; re‑manufacturing belongs to
cradle‑to‑cradle.

**Question 4. Which international green building rating system uses “Credits” for performance
categories?**
A) BREEAM
B) LEED
C) WELL
D) Green Star
Answer: B
Explanation: LEED awards points (credits) across categories such as Energy, Water, and
Materials.
**Question 5. Which regional code emphasizes “Zero Net Energy” for new construction in the
Pacific Northwest?**
A) California Title 24
B] New York Local Law 97
C) Washington State Energy Code (WSEC)
D) Texas Green Building Ordinance
Answer: C
Explanation: WSEC includes provisions encouraging zero net‑energy buildings.
**Question 6. When assessing a site’s solar orientation, which direction provides the greatest
passive solar gain in the Northern Hemisphere?**
A) North
B) South
C) East
D) West
, AICM Certified Green Built Environment
Specialist CGBES Exam
Answer: B
Explanation: South‑facing façades receive the most consistent solar radiation throughout the
year.
**Question 7. Which soil characteristic most directly affects stormwater infiltration capacity?**
A) pH level
B) Bulk density
C) Organic matter content
D) Color
Answer: B
Explanation: High bulk density reduces pore space, limiting infiltration.
**Question 8. Transit‑oriented development (TOD) primarily aims to reduce which
environmental impact?**
A) Indoor air pollutants
B) Vehicle miles traveled (VMT)
C) Building material waste
D) Water consumption
Answer: B
Explanation: TOD encourages high‑density, mixed‑use development near public transit, lowering
VMT.
**Question 9. Which design strategy is most effective at mitigating the urban heat island
effect?**
A) Installing high‑efficiency HVAC systems
B) Using reflective roofing materials (high albedo)
, AICM Certified Green Built Environment
Specialist CGBES Exam
C) Adding interior partitions
D) Increasing ceiling heights
Answer: B
Explanation: High‑albedo roofs reflect solar radiation, reducing surface temperatures.
**Question 10. Light pollution can be minimized by which of the following exterior lighting
practices?**
A) Using high‑intensity floodlights
B) Installing fixtures with full‑cutoff lenses
C) Positioning lights at 45° upward angles
D) Operating lights 24 hours a day
Answer: B
Explanation: Full‑cutoff fixtures direct light downward, reducing glare and skyglow.
**Question 11. What is the typical flow rate reduction of a WaterSense‑labeled faucet
compared with a standard faucet?**
A) 10 %
B) 20 %
C) 30 %
D) 50 %
Answer: C
Explanation: WaterSense faucets reduce flow from 2.2 gpm to about 1.5 gpm, a ~30 %
reduction.
**Question 12. Which landscaping approach conserves water by using plants adapted to local
climate conditions?**
