QUIZ: Water Conservation 101

Green School Water ConservationThe following quiz is from a recent article in Environmental Design + Construction (ED+C) Magazine on water conservation and the elements of facility design. The Green Schoolhouse Series believes in the importance of water conservation and smart usage, and it’s the expertise of our Partners like BRAE, Elkay Manufacturing and Sloan that helps ensure that our Green Schools meet the highest levels of water efficiency.

Post your answers to the quiz in the comments section of this blog post by this Thursday, June 21 for a chance to be mentioned as a “Green Building Guru” on our social media sites!

1.       One of the most regular and predictable of all indoor water uses accounts for about 33 percent of total building water consumption. What is it?

a.       Coffee machines.

b.      Toilet flushing.

c.       Janitorial maintenance.

d.      Restroom faucets.

 

2.       Which of the following is NOT used to treat storm water or greywater for reuse within a facility?

a.       Aerobic pretreatment.

b.      Reverse osmosis.

c.       Rain sensors.

d.      Settling.

 

3.       True or false: Aside from leaks, the three ways that water is eliminated from cooling towers include evaporation, drift and blowdown. The total of these effects equals the cooling towers total makeup water needed.

a.       True.

b.      False.

 

4.       To improve the water efficiency of heating and hot water systems by as much as 70 percent, a retrofit or new construction project can include:

a.       A single-pass cooling system.

b.      Blowdown processes.

c.       Drift elimination.

d.      Condensate return system.

 

5.       A novel restroom fixture technology seen recently in Europe allows users to determine the level of water flow, from ultra-low flow to higher flow levels, based on a mechanical feature. This fixtures work based on…

a.       Resistance to force applied to the handle.

b.      Use of aerators to change the water flow appearance.

c.       A range of setting indicators corresponding to specific water needs.

d.      None of the above.

 

6.       Predevelopment site hydrology includes awareness of both site conditions as well as regional conditions of a natural site before construction-related land disturbance. Which of the following is NOT considered on the assessment of predevelopment hydrology?

a.       Runoff.

b.      Irrigation needs.

c.       Infiltration.

d.      Evapotranspiration rates.

 

7.       True or false: By definition, xeriscaping plantings are (1) appropriate to the local climate, (2) require minimum watering, and (3) contribute to landscaping that minimizes evaporation and runoff.

a.       True.

b.      False.

 

8.       Which of the following statements accurately describes the features or use of rain sensors?

a.       They can be hardwired or wireless.

b.      Some contain hygroscopic disks to activate switches.

c.       They can be combined with freeze sensors.

d.      All of the above.

 

9.       For site installations where irrigation systems are used, assessments of potential water-use reduction goals may be undertaken with a basic punch list or audit, which provides for:

a.       Pre-selection of low-flow restroom fixtures.

b.      Full commissioning of irrigation systems.

c.       Review of site inspection, performance testing and irrigation scheduling.

d.      None of the above.

 

10.   True or false: Two fixtures with the same rated efficiencies will save the same amount of water, regardless of use conditions or end-user behaviors.

a.       True.

b.      False.
