EXAM Q&A WITH RATIONALES
1. A project team is considering the location of a new
building. Which strategy would best support the
Sustainable Sites (SS) credit for "Site Development –
Protect or Restore Habitat"?
A) Building on a previously undeveloped greenfield
B) Restoring a degraded site and planting native
vegetation
C) Increasing the building footprint to maximize land
use
D) Using non-native ornamental grasses for
landscaping
Correct answer: B
Rationale: Restoring degraded sites and planting
native vegetation (or creating a habitat conservation
plan) supports biodiversity and earns the credit.
Building on greenfields (A) typically reduces habitat.
2. Which of the following refrigerants is most
preferred under LEED's "Fundamental Refrigerant
,Management" prerequisite due to its zero ozone
depletion potential (ODP) and low global warming
potential (GWP)?
A) R-22 (HCFC)
B) R-134a (HFC)
C) R-410A (HFC)
D) R-744 (Carbon Dioxide, CO2)
Correct answer: D
Rationale: Natural refrigerants (R-744, R-717) have
zero ODP and low GWP. R-22 (A) has high ODP and is
being phased out. R-134a (B) and R-410A (C) have
zero ODP but high GWP.
3. A building owner wants to reduce water use in
landscaping. Which strategy would contribute to the
"Outdoor Water Use Reduction" credit?
A) Installing a fountain with recirculating water
B) Planting turf grass that requires frequent watering
C) Using native or adapted plants that require no
irrigation after establishment
D) Using spray irrigation at night
Correct answer: C
,Rationale: Selecting native or adapted plants that do
not require permanent irrigation (or using drip
irrigation with high-efficiency fixtures) reduces
outdoor water use. Turf grass (B) is typically water-
intensive.
4. Which of the following is a core concept of the
Integrative Process credit?
A) Designing the building in isolation without input
from other disciplines
B) Conducting a preliminary "Simple Box" energy
modeling analysis during early design to inform
decisions
C) Waiting until construction is complete to evaluate
performance
D) Using a single type of insulation throughout the
building envelope
Correct answer: B
Rationale: The Integrative Process credit requires
early analysis (energy, water, HVAC) to identify
synergies and optimize performance before
decisions are locked in.
5. A project is located within 1/2 mile of a commuter
rail station. This would contribute to which credit
, under the Location and Transportation (LT)
category?
A) High-Priority Site
B) Access to Quality Transit
C) Bicycle Facilities
D) Reduced Parking Footprint
Correct answer: B
Rationale: Access to Quality Transit requires
proximity to bus, light rail, or commuter rail stations.
The distances vary by transit type (e.g., 1/4 mile for
bus, 1/2 mile for rail).
6. A building owner wants to reduce indoor water
use. Which of the following fixtures would contribute
most to the "Indoor Water Use Reduction" credit?
A) Standard 2.5 gallons per minute (gpm)
showerheads
B) 1.6 gallons per flush (gpf) toilets
C) High-efficiency fixtures (e.g., 1.28 gpf toilets, 1.5
gpm showerheads)
D) Pre-rinse spray valves with flow rates of 1.6 gpm
Correct answer: C
