1、Question 1Show Answer LegendWhich item can contribute to Construction Waste ManagementAHazardous construction debrisBFill dirtCConcreteDSteel and wallboardNotes:Hazardous debris does not qualify for this credit; therefore, hazardous construction debris is incorrect.Fill dirt does not qualify for thi
2、s credit; therefore, fill dirt (excavated soil) is incorrect.Question 2Show Answer LegendA project team has decided to shrink the building footprint. This change can have a positive impact on what issueACar pool parkingBParking capacityCPedestrian accessDOpen spaceNotes:Reducing the size of the buil
3、ding footprint may allow for more open space (fields, grasslands, landscaping, etc.)Open space are the ground areas that are vegetated and pervious.Green roofs can be considered open space but only for urban areas.For the purposes of LEED, open space is the property area minus the development footpr
4、int, when local zoning does not define open space.Question 3Show Answer LegendWhat would contribute to community connectivityAA site with pedestrian access between basic servicesBA site near mass transitCA site near public parkingDA site near a restaurantNotes:Community connectivity channels develop
5、ment to urban areas with existing infrastructure. This includes areas with walkways and areas near basic services.Basic services are those services that are open to the public, and are common services that people might use regularly. People must be able to walk between the project and the service wi
6、thout being blocked by walls, highways, or other barriers (this is called pedestrian access). LEED encourages building near a variety of basic services, not just one type of service such as twelve clothing stores in a strip mall. LEED provides examples of basic services as:BankChurchSupermarket / co
7、nvenience storeDay careDry cleaner / laundry matFire stationSalonHardware storeLibraryMedical / dental officeParkPharmacyPost officeRestaurantSchoolTheatre / museumCommunity centerGymAccess to public transpiration (mass transit) helps with reducing automobile use in the LEED Rating System, however p
8、icking a site near mass transit does not help earn the community connectivity credit.The answer choice of public parking is incorrect because a parking lot or parking garage is not defined by LEED as a service. A public park is defined by LEED as a basic service.Question 4Show Answer LegendWho is re
9、sponsible for the development of the LEED Rating SystemsAArchitects, engineers, and contractors onlyBProduct manufacturersCLocal, state, and federal government agenciesDVolunteersNotes:The intent of this question is to learn the LEED Rating Systems are developed by committees of volunteers from all
10、types of backgrounds.From USGBCs website:LEED Rating Systems are developed through an open, consensus-based process led by LEED committees. Each volunteer committee is composed of a diverse group of practitioners and experts representing a cross-section of the building and construction industry.Whil
11、e it is true employees of local, state, and federal government agencies can volunteer for the committees, as can product manufacturers and architects, engineers, and contractors, it is volunteers that make up the committees from these professions as well as many others.Question 5Show Answer LegendWh
12、at is the goal of providing secure bicycle storageATo keep bicycles dryBTo meet local regulationsCTo prevent theftDTo increase the life cycle of bicyclesNotes:Glossary: Secure storage is any method or methods that prevent theftQuestion 6Show Answer LegendWastewater from sinks can:ASometimes be recyc
13、led and used for irrigation, depending on local codesBAlways be recycled and used for irrigationCNever be recycled and used for irrigationDAlways be used for makeup water in cooling towersNotes:Reference: USGBC GlossaryWastewater treatment systems are sometimes used in projects to treat wastewater a
14、nd reuse it onsite for non-potable uses such as irrigation and for flushing fixtures.Blackwater does not have a single definition accepted nationwide. Adjacent cities may have different codes that allow or prohibit the use of sink/shower water for non-potable uses. On jurisdiction may define sink/sh
15、ower water as blackwater and not permit its use, while another may define it as graywater and will permit its use. Review local codes before making design decisions based on the use of wastewater.Question 7Show Answer LegendWhat is the baseline water demand of a buildingAThe annual fixture and fitti
16、ng water consumption based on the rates from the EPAct 1992 standardBThe annual installed fixture and fitting water consumption rateCThe amount of graywater and rainwater harvesting a building is planning to useDThe annual water rate as determined by water billsNotes:To calculate water consumption i
17、n a building, a baseline water demand is compared to an installed design case.The baseline demand uses the fixture and flow rates from the EPAct 1992 standard. For example, commercial toilets have 1.6 gallons per flush, commercial urinals have 1.0 gallons per flush. These rates for all toilets, urin
18、als, and faucets are used to create a baseline. Also used is the number of Full Time Equivalents (FTEs) to determine how frequently the fixtures will be used.The design case water consumption (or design demand) calculates the rates based on the higher efficiency fixtures that will be installed. For
19、example if waterless urinals are used the design case will calculate them at their zero gallon per flush rate. The percent in water savings is determined by dividing the design case by the baseline case and subtracting that from the number 1Example:Baseline case: 100,000 gallons of water / yearDesig
20、n case: 60,000 gallons of water /year60,000/100,000 = 0.61 -0.6 = 0.4Percent reduction = 40% reductionQuestion 8Show Answer LegendWhat types of systems are not acceptable by LEED as sources of renewable energyALow-impact hydroelectric power systemsBBiomassCWindDHigh-impact hydroelectric power system
21、sNotes:This question asks what choices arenotacceptable by LEED as sources of renewable energy.While low-impact hydroelectric power systems are accepted, high-impact hydroelectric power systems are not. High-impact hydropower is not considered environmentally friendly because of water quality issues
22、, and the negative impact it has on fish and wildlife.Question 9Show Answer LegendWhat is a characteristic of open-grid pavementAIt is 100% imperviousBVegetation can grow in itCIt is at least 50% imperviousDIt is at least 75% imperviousNotes:Reference: O+M GlossaryOpen grid pavement is pavement that
23、 is less than 50% impervious and contains vegetation in the open cells.Here is an example of open grid pavement:Open grid pavement is different than pervious pavement.Pervious pavement is designed to allow percolation or infiltration of stormwater through the surface into the soil below where the wa
24、ter is naturally filtered and pollutants are removed. In contrast normal pavement is an impervious surface that sheds rainfall and associated surface pollutants forcing the water to run off paved surfaces directly into nearby storm drains and then into streams and lakes.Here is an example of perviou
25、s pavement:Question 10Show Answer LegendIn a state with a closed electricity market, how can off-site green power be purchasedAThrough an ENERGY STAR approved utility providerBEnroll in a Green-e renewable power program from the utility providerCHave certified wood scraps delivered onsite for burnin
26、gDPurchase power from a USGBC approved providerNotes:Some utility companies allow the purchase of renewable energy, sometimes for a price premium. Make sure the source of the energy is Green-e certified.Question 11Show Answer LegendOzone-friendly refrigerants differ from ozone-damaging refrigerants
27、in what wayAOzone-friendly refrigerants are global warming neutralBOzone-friendly refrigerants may cause less global warmingCOzone-friendly refrigerants may cause more global warmingDOzone-friendly refrigerants are more energy efficientNotes:According to Treatment by LEED of Environmental Impact of
28、HVAC Refrigerants, some refrigerants cause more ozone depletion than others, but the most ozone-friendly refrigerants cause more global warming.HFCs, while generally better for the environment in regards to ozone depletion potential, are less efficient than HCFCs. Because they are less efficient a b
29、uilding that uses HFC refrigerants must spend more energy to keep the building as cool compared to using HCFC refrigerants. Using more energy to cool the building uses more fossil fuels to run the HVAC equipment and generates more pollution, thereby increasing the greenhouse effect and global warmin
30、g.Question 12Show Answer LegendAt a minimum, a project team must successfully do which of the following to obtain LEED certificationAGather documentation for the prerequisitesBHire a USGBC approved consultantCRecord all vendors used on the projectDGather documentation for 40 points of the 110 points
31、 availableNotes:Projects must meet all prerequisites to earn LEED certification.The minimum number of points required for certification is 40.USGBC consultants are not required for projects.The product vendors are not needed when submitting documentation on the project.Question 13Show Answer LegendW
32、hat issues do the ASHRAE standards NOT addressAPlumbing codesBThermal comfortCEnergy efficiencyDHeat island measurementNotes:ASHRAE 62.1-2007 Ventilation for Acceptable Indoor Air Quality specifies minimum ventilation rates. These rates are used to improve indoor air quality as part of the IEQ credi
33、t category.ASHRAE 55-2004 Thermal Environmental Conditions for Human Occupancy help with defining what makes a comfortable indoor environment for occupants. Indoor conditions are considered acceptable if 80% or more of occupants find them acceptable.ASHRAE 90.1-2007 establishes minimum requirements
34、for the energy efficient design of buildings (not included are single family homes or multifamily homes less than 3 stories).Question 14Show Answer LegendLEED for New Construction, Core & Shell, Schools, and Existing Buildings: Operations & Maintenance were designed to evaluate what building typesAH
35、igh-rise residential buildingsBInterior spacesCCommercial buildingsDCommunity developmentEInstitutional buildingsNotes:Reference: GBCI website, Minimum Project RequirementsYou should go to gbci.org and review the Minimum Project Requirements page.Question 15Show Answer LegendWhich of the following d
36、oes not help achieve a water-efficient landscapeAInstalling hardscapesBPerennialsCAdaptive plantingsDOverhead sprinklersNotes:Overhead sprinklers contribute to runoff and evaporation by wind and sun.Hardscapes can increase the heat island effect and stormwater runoff, but they do reduce the size of
37、the area that needs irrigation.Question 16Show Answer LegendWhat type of water is rainwaterAGraywaterBBlackwaterCNon-potable waterDPotable waterNotes:Potable water is water which is fit for consumption by humans and other animals. It is also called drinking water, in a reference to its intended use.
38、 Water may be naturally potable, as is the case with pristine springs, or it may need to be treated in order to be safe.In most jurisdictions rainwater is considered non-potable and is therefore considered non-potable.Question 17Show Answer LegendA door found onsite and turned into a table as part o
39、f a major renovation would automatically qualify as:AComingled materialBRegional materialCRapidly renewable materialDPre-consumer contentNotes:The door would be extracted (salvaged) and used within 500 miles, qualifying it as regional material.Question 18Show Answer LegendWhat does the IPMVP Volume

41、e III is used for measurement & verification, and provides best practice techniques for verifying the energy performance of a new building.You can view the IPMVP v3 here if you want to take a quick look: Dont spend too much time in this document - the link is only provided to reinforce your knowledg
42、e. The document isnt in the exam reference materials so dont read this document for more than a minute.The standard is used in the rating systems and you should be familiar with what the standard is used for.Question 19Show Answer LegendHow should a project team view all green building costs when bu
43、dgeting for a projectAIndividuallyBAs soft costsCSynergisticallyDCumulativelyNotes:The best answer for this question is synergistically. Costs are not cumulative since the cost of adopting one sustainable strategy for LEED may assist in earning points in other areas. Costs are also not individual co
44、sts for this reason. LEED of course includes soft costs, but not all LEED elements will be soft costs.Question 20Show Answer LegendWhat needs to be done for water managementAInstall an onsite wastewater systemBUse waterless urinalsCUse drip irrigationDEstablish a baseline water demandNotes:The first
45、 step in water management is determining how much water is being used, or will be used. This baseline allows project teams to determine how much they can save.Question 21Show Answer LegendHow long must an existing building be occupied before the LEED application process may begin for LEED for Existing Buildings: Operations and Maintenance certificationAThe application process can begin as soon as regular occupancy is reachedB3 monthsC6 monthsD12 monthsNotes:This question is asking about the
