SFP Water Management & Conservation

Question 1

Which fixture type is most effective for reducing potable water use in commercial restrooms?

Accepted Answer

Low-flow toilets with dual-flush technology

Answer

Dual-flush low-flow toilets allow users to select a lower flush volume for liquid waste, significantly reducing overall water consumption compared to single-flush models.

Question 2

What does 'Water Use Intensity' (WUI) measure in a facility context?

Accepted Answer

Water consumption per square foot of conditioned space

Answer

WUI normalizes water consumption by dividing total water use by the facility's conditioned floor area, enabling meaningful benchmarking across similar building types.

Question 3

A cooling tower at a facility is experiencing a cycles of concentration (COC) of 2. What does increasing COC to 5 primarily achieve?

Accepted Answer

Reduces blowdown water discharge and overall water consumption

Answer

Higher cycles of concentration mean water is reused more times before blowdown, directly reducing the volume of water discharged and makeup water needed.

Question 4

Which LEED v4 credit category addresses outdoor water use reduction?

Accepted Answer

Water Efficiency — Outdoor Water Use Reduction

Answer

LEED v4's Water Efficiency category includes the Outdoor Water Use Reduction credit, which rewards strategies like native plantings, efficient irrigation, and non-potable water sources for landscaping.

Question 5

Greywater systems in facilities typically collect water from which sources for reuse?

Accepted Answer

Lavatories, showers, and laundry — excluding toilet waste

Answer

Greywater is lightly contaminated wastewater from sinks, showers, and laundry that can be treated and reused for toilet flushing or irrigation without full sewage treatment.
