True or False: The LEED program covers the indoor air quality of a building.

FALSE

What is a "no disturbance zone"?
an area on a property where plants and trees cannot be cut down
Under LEED guidelines, a "no disturbance zone" is a special part of the property where no trees or plants can be removed. For new construction, the zone can be an area where new foliage is planted. Luckily for wildlife, though, LEED does award points for buildings that steer clear of endangered habitats.

a sound-proofed area of a home

What percentage of the yard must be dedicated to a "no disturbance zone" to get a credit under the LEED guidelines?
100 percent
at least 80 percent
at least 40 percent
At least 40 percent of a yard needs to be set aside for plants and trees to grow to take full advantage of LEED certification credits. Areas underneath the roof and eaves of the house cannot count toward the 40 percent.

How close should a LEED home be to existing water and sewer lines to claim certification credit?
within one-half mile
To claim this particular credit, LEED homes need to be built within one-half a mile of existing water and sewer infrastructure. Building houses close to existing water lines reduces the amount of disruption to the soil and plant life required to put in new utilities.
within 1 mile
within 100 yards

Which of these natural features should NOT be located near a LEED home in order to claim certification credits?
wetlands
Home builders can claim credits for homes that aren't built within 100 feet of any wetlands or bodies water, including swamps, bogs and lakes.
mountains
deserts

As a prerequisite for certification, all LEED homes must meet minimum requirements under which other energy standard?
ENERGY STAR
The EPA's ENERGY STAR standards award a special status to homes that are 20 to 30 percent more energy efficient than the average home, and LEED uses those energy standards as the baseline for its own efficiency requirements. Homes can earn additional points when they exceed ENERGY STAR.
California's energy efficiency standards

True or False: A builder can earn LEED points for a building when he or she educates its tenants or buyers on green living.
TRUE
True. The USGBC doesn't want to award a certification for a building, only for it to be sold to someone who leaves the water running all day, cancelling out the environmental benefits of the property. So, builders or owners who sell or rent a certified property can claim points for making efforts to teach the new residents how to use a LEED home to its full green potential.

What is the maximum percentage of a new construction's budget that can be spent on wasted materials, under LEED guidelines?
0 percent
8.3 percent
Out of all the money spent on building materials, 8.3 percent -- at most -- can be spent on materials that go to waste. Of course, LEED credits are available for builders who go above and beyond that maximum in their attempt to limit wasted construction materials.
12.6 percent

What is the urban heat island effect?
the tendency of urban areas to be hotter than rural areas, because of heat absorbed by stone, concrete, roofing material and metal
Because urban areas tend to absorb more sunlight and heat up quickly, LEED guidelines provide credits for builders who make efforts to reduce the effect on their green properties. The increased heat of urban areas results in more energy being used to keep the inside of buildings cool during the summer.

What does the term "high-albedo" mean?
It refers to a material that reflects more sunlight than it absorbs.
"High-albedo" is a term that describes any substance that reflects most of the light that hits it. High-albedo materials are useful in green construction and LEED certification, because they reduce the urban heat island effect.
It means that the water coming from a home's pipes is too toxic to be consumed.
It describes a LEED building that has the highest certification level.

What is "conventional turf"?
a typical grass lawn
Green is not always good when it comes to the environment. Conventional turf, or any typical grass lawn, requires a large amount of mowing and water to maintain. So, LEED guidelines award points for homes that use less grass than materials like mulch and plantings. The less grass, the more points are awarded.
a synthetic type of grass
a type of grass that is more environmentally friendly

What is gray water?
another word for rainwater
water that is recycled from drains, washing machines and showers
Gray water, or re-filtered water that is recycled from showers, sink drains and gutters, can be reused for irrigation. LEED guidelines award points for homes that have gray-water recycling systems installed.

True or False: LEED gives no points for environmental improvements that aren't outlined in the standards.
TRUE
FALSE
False. LEED guidelines provide up to six bonus certification points for green design features that go above and beyond the standards the USGBC has outlined. Many builders hire LEED experts to help them score these bonus points.

How many gallons per flush must a LEED home's toilets use?
1.6 gallons
1 gallon
There is no firm requirement.
Unlike businesses, which must meet strict water use thresholds for all toilets they install, homes don't need to meet any requirements for toilet water consumption to get LEED certified. But the program does have credit points that can be awarded when homes use toilets and other fixtures that conserve water.

True or False: To be certified, LEED homes must be subjected to a process called "commissioning" to make sure they are using energy efficiently.
TRUE
FALSE
False. The intense commissioning process is only necessary for businesses, which have much more extensive energy use needs than the typical home. Homes need only meet ENERGY STAR requirements to be eligible for LEED certification.

True or False: LEED-certified homes cannot contain fireplaces.
TRUE
FALSE
While home builders can take credit points for not installing fireplaces into homes, having a fireplace is not a deal breaker for LEED certification. Even if a home does have a fireplace, it can still qualify for some additional points if it meets certain emissions standards.
