LEED (Leadership in Energy and Environmental Design Certification) Water Efficiency 2

Question 1

Which LEED credit category specifically addresses cooling tower water management?

Accepted Answer

Cooling Tower Water Management

Answer

LEED has a dedicated Cooling Tower Water Management credit that targets water efficiency in HVAC cooling systems.

Question 2

What is the baseline flush volume (gpf) for a standard tank-type toilet under LEED Water Efficiency calculations?

Accepted Answer

1.6 gpf

Answer

LEED v4 uses 1.6 gpf as the baseline for tank-type toilets when calculating water use reduction.

Question 3

A building installs a greywater system to flush toilets. Which LEED prerequisite or credit does this strategy primarily support?

Accepted Answer

Indoor Water Use Reduction

Answer

Using greywater for toilet flushing directly reduces potable water consumption for indoor fixtures, supporting the Indoor Water Use Reduction credit.

Question 4

Under LEED v4, which of the following appliances is NOT typically included in the indoor water use baseline calculation?

Accepted Answer

Cooling towers

Answer

Cooling towers are addressed in a separate LEED credit (Cooling Tower Water Management) rather than the indoor water use baseline fixtures.

Question 5

What does 'potable water' mean in the context of LEED Water Efficiency credits?

Accepted Answer

Water that meets drinking water quality standards

Answer

Potable water meets drinking water quality standards and is suitable for human consumption; LEED credits aim to reduce its use wherever non-potable alternatives suffice.
