Accepted Answer

40 gpm

Answer

60 gpm

Answer

10 gpm

Answer

50 gpm

Question 2

Which of the following best describes a 'water balance' for a facility?

Accepted Answer

An accounting of all water inputs, uses, and outputs across the site

Answer

The ratio of hot to cold water in the domestic plumbing system

Answer

A hydraulic model of pipe pressure throughout the building

Answer

The difference between potable water cost and sewer charges

Question 3

What is the main advantage of using a soil moisture sensor in a landscape irrigation system?

Accepted Answer

It prevents irrigation when soil already contains sufficient moisture

Answer

It increases water pressure to improve sprinkler coverage

Answer

It filters sediment from irrigation water before application

Answer

It automatically adjusts the irrigation schedule based on plant growth stage

Question 4

According to ASHRAE 191, a facility's water efficiency standard should prioritize which hierarchy of water sources?

Accepted Answer

Reduce demand first, then reuse and recycle, then use potable supply as last resort

Answer

Use potable supply first, then reclaimed water, then harvested rainwater

Answer

Treat all water sources equally based on cost-effectiveness

Answer

Maximize stormwater harvesting before any other conservation measure

Question 5

Which type of landscape design approach is most aligned with sustainable water management in arid US climates?

Accepted Answer

Xeriscaping with drought-tolerant native plantings

Answer

Dense turf grass with automated irrigation schedules

Answer

Raised garden beds with high daily watering requirements

Answer

Ornamental water features with continuous recirculation

Question 6

What is the purpose of submetering water in a multi-tenant facility?

Accepted Answer

To allocate water costs accurately and identify tenant-level consumption anomalies

Answer

To increase water pressure to upper floors

Answer

To comply with federal drinking water quality standards

Answer

To reduce the size of the main utility meter required

Question 7

A facility installs a condensate recovery system on its air handling units. What is the primary benefit?

Accepted Answer

It captures distilled-quality water that can offset cooling tower make-up or irrigation demand

Answer

It reduces refrigerant charge in the chiller plant

Answer

It improves indoor air quality by lowering humidity at the coil

Answer

It eliminates the need for water treatment chemicals in the HVAC loop
