LEED Water Efficiency Concepts 2

Question 1

Which LEED credit category specifically addresses outdoor water use reduction?

Accepted Answer

Water Efficiency: Outdoor Water Use Reduction

Answer

The Water Efficiency credit category includes Outdoor Water Use Reduction, which targets landscape irrigation.

Question 2

What is the baseline irrigation requirement used to calculate outdoor water use reduction in LEED?

Accepted Answer

A calculated mid-summer peak-week irrigation demand

Answer

LEED uses a calculated mid-summer peak-week water demand baseline for the site's landscape to measure outdoor water savings.

Question 3

A building project installs a green roof with drought-tolerant sedums and no irrigation. How does this affect LEED Water Efficiency credits?

Accepted Answer

It can earn points by reducing or eliminating outdoor potable water use

Answer

A non-irrigated green roof reduces outdoor potable water consumption, contributing to Outdoor Water Use Reduction credit.

Question 4

Which measurement unit does LEED use to express indoor water use reduction compared to a baseline?

Accepted Answer

Percent reduction in annual gallons per occupant

Answer

LEED expresses indoor water savings as a percentage reduction in annual gallons per occupant versus the calculated baseline.

Question 5

Under LEED, which fixture type is NOT typically included in the indoor water use baseline calculation?

Accepted Answer

Irrigation controllers

Answer

Irrigation controllers manage outdoor water and are addressed under the outdoor water credit, not the indoor water baseline.
