考试相关信息一、如何选取正确的培训机构目前互联网上流传着一些拷贝友绿课表、拷贝友绿复习资料的所谓培训机构，因为现在互联网技术的成熟，建设一个网站的成本十分低廉，在网络上进行传播的途径也很多，并且没有任何成本，比如百度贴吧，百度问答，QQ空间，QQ群，BBS等，故一些完全没有任何资质的骗子公司大行其道。

去年央视报道的百度搜索作恶的问题，就反映了这一现象：一些图谋不轨的个人在网上散布维修、培训等虚假信息，拷贝正规公司的业务介绍和页面设计，看起来和真的一样，但一旦交钱，发现服务完全不是所承诺的那样，拿了钱电话就不通了。

为避免类似情况的发生，保障广大对LEED感兴趣的绿色建筑爱好者和从业者，我们给出以下判断标准，用于识别那些假公司或皮包公司：1.如果要缴费，一定要索取正规发票，目前国家税收制度改革，统一为增值税发票，但对培训企业，一定要求开具培训费发票；2.查看公司的工商注册，是否正规注册，有无正规经营场所；查看公司营业执照，注册资金是否与实际相符合，通常国家规定最低注册资金为10万，注册资金越高，部分的反映了公司的实力；3.对于LEED培训，一定要询问对方是否能出具资质证明，USGBC仅允许授权的Education Provider在当地提供LEED相关培训服务， Education Provider 的课程要经过USGBC的严格审核之后，才能发布到网站上，大家也可以在这个网站上查找合格的课程；4.看讲师素质，LEED看起来简单，但要讲好，讲深入，讲的有用，无论对做项目，还是对考试都得有用，就必须有至少5-10年的实际项目操作经验，否则照本宣科，还不如自己自学；5.正规的培训网站，都会列出有照片，有真实姓名的讲师介绍，可在类似的QQ群查询这些人，是否在被业内人士认可；6.友绿网作为业内第一家，到目前为止，也是唯一一家USGBC授权的Ecudation Provider，最早在网上发布了很多LEED GA 和LEED AP的介绍和答疑，被一些网站非法盗用，大家可检索对比是否具有系统性和连贯性，以及与友绿网的相似度，来判断是否原创；7.目前网上流行的课表，99%都是从友绿网拷贝过去的，可查一下与友绿网公布课表的差别，基本也能辨别这家公司是否具备开展这项业务起码的诚意——做一张自己的课表。

For example instead of having a 1 story页脚内容8building with a 10,000 SF footprint design a 2 story building with a 5,000 SF footprint. Both designs have 10,000 SF of total floor area but the 2 story building has a smaller footprint.C The LEED project boundary changesThe project boundary would remain unchanged. Only the building footprint changes - not the site area.D The building footprint increasesThe building footprint would decrease because the project is building up rather than out.Question 25 of 100页脚内容9What are the benefits of becoming a tenant or owner of a building that is certified under LEED for NewConstruction if the project team wants to also certify under LEED for Commercial Interiors?A There are no certification feesB There is no registration feeGBCI offers free registration for LEED for Existing Buildings: Operations & Maintenance for projectscertified under LEED for New Construction, LEED for Schools, and LEED for Core & Shell prior to January1, 2011.If the question had asked about the project team wanting to certify under LEED for Existing Buildings:Operations & Maintenance, a correct answer choice would also be 'There is no registration fee'.C The project will be well situated to earn the additional certification(s)A building that has a prior LEED certification is in a better position to earn additional LEEDcertifications.D Certification fees are reducedC页脚内容10D页脚内容11C页脚内容12A页脚内容13Question 37 of 100LEED Online can be used for all of the following except:A Managing public facing project detailsWhat are public facing project details?You can search USGBC's website to find out about specific projects going on. LEED Online can be used to show/limit what is displayed to the public. For example using LEED Online you would enter in 'Project ABC is going to have a budget of $10M'. You probably don't want anyone to see the project budget so you could hide that detail from public view.Managing the public facing details of the project means this: The person who is the administrator of the project can use LEED online to pick and choose what details they want to make available to the public. For页脚内容14example, 'do you want everyone to know your project budget', check yes or no. 'Do you want everyone toknow the project's address', check yes or no. Using LEED Online the administrator restricts or allows access to this and other various project information. USGBC may then reveal any information that has been marked as publicaly available.B Accessing online reference guidesReference guides are not available in LEED Online.C Submit technical inquiries regarding LEED CreditsD Document compliance with LEED Credit RequirementsB页脚内容15B页脚内容16页脚内容17A页脚内容18AD页脚内容19C页脚内容20CC页脚内容21Question 58 of 100The process of green building begins with the idea of the project and continues until:A The schematic design is completedB The project is reused or recycledGreen building continuously improves a project from when the idea is first realized in a person's head to页脚内容22when the project is finally either reused for a different purpose or it is demolished and hopefully recycled.This differs from conventional design where all trades are not involved in all parts of the process throughthe project's life cycle.C The construction documents are preparedD The project begins operatingB页脚内容23页脚内容24页脚内容25B页脚内容26C页脚内容27A页脚内容28AIf the project team was denied a credit the team may appeal. Appeals are allowed for design phase and construction phase credits if a split review is being done. Otherwise the appeals come after the final review.Appeals are $500 per credit - no discounts.页脚内容29Question 78 of 100What is applicable to the ongoing operations and maintenance of a building?A Sustainable purchasing policySustainable purchasing policies give preference to the purchase of environmentally preferable products and the companies that supply them. For ongoing operations and maintenance it is required to a have a policy in place to address product purchases for the building. The program should address ongoingconsumables, like office paper and printer cartridges, as well as durable goods like computers andfurniture.B Passive design strategiesPassive design strategies such as natural ventilation and daylighting are part of building design.C CommissioningCommissioning is the systematic process of assuring that a building and its systems performs in accordance with the design intent and the owner's requirements. This is part of building construction.D Floor area ratio页脚内容30The FAR would be used during planning and construction. A页脚内容31AFor O&M the building must be in a state of typical physical occupancy.For example, a hotel usually has a typical occupancy of about 60% of the rooms rented out. The O&M certification could not be attempted until the hotel was at least 60% occupied. If the hotel was just constructed and didn't have any occupants the certification could not be earned.A school dormitory is another example. If the dormitory was completed in April but will not be occupied until the fall semester in September, the project is not yet in typical occupancy because no students are living in the dorm between April - August.页脚内容32页脚内容33页脚内容34页脚内容35CThe heat island effect refers to the ability of dark, non-reflective paved areas-city streets, rooftops, and sidewalks-to absorb and radiate heat, making urban areas and the surrounding suburbs noticeably hotter than rural towns nearby. Other contributors include reduced air flow due to tall buildings and narrow streets, calm and sunny weather, and auto exhaust.页脚内容36页脚内容37页脚内容38BD页脚内容39。

What does LPE mean? 在线LEE D的一些分值都有一个LPE选项。

Question 1Show Answer Legend Which item can contribute to Construction Waste Management?A Hazardous construction debrisB Fill dirtC ConcreteD Steel and wallboardNotes:Hazardous debris does not qualify for this credit; therefore, hazardous construction debris is incorrect.Fill dirt does not qualify for this credit; therefore, fill dirt (excavated soil) is incorrect.Question 2Show Answer Legend A project team has decided to shrink the building footprint. This change can have a positive impact on what issue?A Car pool parkingB Parking capacityC Pedestrian accessD Open spaceNotes:Reducing the size of the building 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 footprint, when local zoning does not define open space.Question 3Show Answer Legend What would contribute to community connectivity?A A site with pedestrian access between basicsB A site near mass transitC A site near public parkingD A site near a restaurantNotes:Community connectivity channels development to urban areas with existinginfrastructure. This includes areas with walkways and areas near basics.Basics are thoses that are open to the public, and are commons that people might use regularly. People must be able to walk between the project and the without being blocked by walls, highways, or other barriers (this is called pedestrian access). LEED encourages building near a variety of basics, not just one type of such astwelve clothing stores in a strip mall. LEED provides examples of basics as:BankChurchSupermarket / convenience 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 picking 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. A public park is defined by LEED as a basic.Question 4Show Answer Legend Who is responsible for the development of the LEED Rating Systems?A Architects, engineers, and contractors onlyB Product manufacturersC Local, state, and federal government agenciesD VolunteersNotes:The intent of this question is to learn the LEED Rating Systems are developed by committees of volunteers from all types of backgrounds.From USGBC's 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.'While 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 Legend What is the goal of providing secure bicycle storage?A To keep bicycles dryB To meet local regulationsC To prevent theftD To increase the life cycle of bicyclesNotes:Glossary: Secure storage is any method or methods that prevent theftQuestion 6Show Answer Legend Wastewater from sinks can:A Sometimes be recycled and used for irrigation, depending on local codesB Always be recycled and used for irrigationC Never be recycled and used for irrigationD Always be used for makeup water in cooling towersNotes:Reference: USGBC GlossaryWastewater treatment systems are sometimes used in projects to treat wastewater and reuse it onsite for non-potable uses such as irrigation and for flushing fixtures.Blackwater does not have a single definition accepted nationwide. Adjacent citiesmay have different codes that allow or prohibit the use of sink/shower water fornon-potable uses. On jurisdiction may define sink/shower 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 Legend What is the baseline water demand of a building?A The annual fixture and fitting water consumption based on the rates from the EPAct 1992 standardB The annual installed fixture and fitting water consumption rateC The amount of graywater and rainwater harvesting a building is planning to useD The annual water rate as determined by water billsNotes:To calculate water consumption in 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, urinals, 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 onthe higher efficiency fixtures that will be installed. For example if waterlessurinals 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 / yearDesign case: 60,000 gallons of water /year60,000/100,000 = 0.61 -0.6 = 0.4Percent reduction = 40% reductionQuestion 8Show Answer Legend What types of systems are not acceptable by LEED as sources of renewable energy?A Low-impact hydroelectric power systemsB BiomassC WindD High-impact hydroelectric power systemsNotes:This question asks what choices are not acceptable 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, and the negative impact it has on fish and wildlife.Question 9Show Answer Legend What is a characteristic of open-grid pavement?A It is 100% imperviousB Vegetation can grow in itC It is at least 50% imperviousD It is at least 75% imperviousNotes:Reference: O+M GlossaryOpen grid pavement is pavement that is less than 50% impervious and contains vegetation in the open cells.Here is an example of open grid pavement:i.treehugger./files/th_images/hastings.jpgOpen 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 water 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 pervious pavement:.us-concrete./images/news_pervious_a.jpgQuestion 10Show Answer Legend In a state with a closed electricity market, how can off-site green power be purchased?A Through an ENERGY STAR approved utility providerB Enroll in a Green-e renewable power program from the utility providerC Have certified wood scraps delivered onsite for burningD Purchase 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 Legend Ozone-friendly refrigerants differ from ozone-damaging refrigerants in what way?A Ozone-friendly refrigerants are global warming neutralB Ozone-friendly refrigerants may cause less global warmingC Ozone-friendly refrigerants may cause more global warmingD Ozone-friendly refrigerants are more energy efficientNotes:According to Treatment by LEED of Environmental Impact of 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 building 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 usesmore fossil fuels to run the HVAC equipment and generates more pollution, thereby increasing the greenhouse effect and global warming.Question 12Show Answer Legend At a minimum, a project team must successfully do which of the following to obtain LEED certification?A Gather documentation for the prerequisitesB Hire a USGBC approved consultantC Record all vendors used on the projectD Gather documentation for 40 points of the 110 points 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 Legend What issues do the ASHRAE standards NOT address?A Plumbing codesB Thermal comfortC Energy efficiencyD Heat 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 credit category.ASHRAE 55-2004 Thermal Environmental Conditions for Human Occupancy help withdefining what makes a comfortable indoor environment for occupants. Indoorconditions are considered acceptable if 80% or more of occupants find them acceptable.ASHRAE 90.1-2007 establishes minimum requirements 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 types?A High-rise residential buildingsB Interior spacesC Commercial buildingsD Community developmentE Institutional buildingsNotes:Reference: GBCI website, Minimum Project RequirementsYou should go to and review the Minimum Project Requirements page.Question 15Show Answer Legend Which of the following does not help achieve a water-efficient landscape?A Installing hardscapesB PerennialsC Adaptive plantingsD Overhead 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 the area that needs irrigation.Question 16Show Answer Legend What type of water is rainwater?A GraywaterB BlackwaterC Non-potable waterD Potable waterNotes:Potable water is water which is fit for consumption by humans and other animals. Itis also called drinking water, in a reference to its intended use. Water may be naturally potable, as is the case with pristine springs, or it may need to betreated in order to be safe.In most jurisdictions rainwater is considered non-potable and is thereforeconsidered non-potable.Question 17Show Answer Legend A door found onsite and turned into a table as part of a major renovation would automatically qualify as:A Comingled materialB Regional materialC Rapidly renewable materialD Pre-consumer contentNotes:The door would be extracted (salvaged) and used within 500 miles, qualifying it as regional material.Question 18Show Answer Legend What does the IPMVP Volume III provide information on?A Best practices for verifying the energy performance of a new buildingB Best management practices for construction activity pollution preventionC Government restrictions for the water flow limits of fixturesD Best design techniques for acoustics in schoolsNotes:The IPMVP Volume III is used for measurement & verification, and provides bestpractice techniques for verifying the energy performance of a new building.You can view the IPMVP v3 here if you want to take a quicklook: /ref/41/40512.pdfDon't spend too much time in this document - the link is only provided to reinforce your knowledge. The document isn't in the exam reference materials so don't readthis 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 Legend How should a project team view all green building costs when budgeting for a project?A IndividuallyB As soft costsC SynergisticallyD CumulativelyNotes: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 pointsin other areas. Costs are also not individual costs for this reason. LEED of course includes soft costs, but not all LEED elements will be soft costs.Question 20Show Answer Legend What needs to be done for water management?A Install an onsite wastewater systemB Use waterless urinalsC Use drip irrigationD Establish a baseline water demandNotes:The first step in water management is determining how much water is being used, orwill be used. This 'baseline' allows project teams to determine how much they can save.Question 21Show Answer Legend How long must an existing building be occupied before the LEED application process may begin for LEED for Existing Buildings: Operations and Maintenance certification?A The application process can begin as soon as regular occupancy is reachedB 3 monthsC 6 monthsD12 monthsNotes:This question is asking about the Existing Buildings: Operations and Maintenance rating system.For this rating system, the LEED project must be in a state of typical physical occupancy, and all building systems must be operating at a capacity necessary to serve the current occupants, for a period that includes all performance periods as well as at least the 12 continuous months immediately preceding the first submission for a review.In short, for Existing Buildings: Operations and Maintenance you must wait twelve months after the building is occupied before applying (not registering, applying). LEED requires this because this provides 12 months worth of utility bills which are needed for measurements.Question 22Show Answer Legend What does the baseline water case represent?A Flow and flush rates of all design case fixturesB The Energy Policy Act of 1992 (EPAct 1992) flow and flush ratesC The amount of water metered for the building's indoor areasD The amount of water metered for the entire projectNotes:All Water Efficiency credits measure water savings by comparing a baseline case against the proposed design case. The baseline case uses the flow and fixture rates from the EPAct 1992 standard.The baseline water usage is based on estimated occupant usage (Full Time Equivalent calculations) and the water fixtures and fittings, such as:Commercial toilets have a baseline water use of 1.6 gallons per flushCommercial urinals have a baseline water use of 1.0 gallons per flushCommercial lavatory faucets have a baseline water use of 2.2 gallons per minuteResidential toilets have a baseline water use of 1.6 gallons per flushResidential lavatory faucets have a baseline water use of 2.2 gallons per minute Residential kitchen faucets have a baseline water use of 2.2 gallons per minute Residential showerheads have a baseline water use of 2.5 gallons per minuteQuestion 23Show Answer Legend Which of the following is a strategy to prevent stormwater runoff?A Minimizing the quantity of open space in the project boundaryB Installing a vegetated roofC Replacing native plants with turf grass to capture and filter the waterD Locating the building 40 feet from a water bodyNotes:A vegetated roof helps capture stormwater on a roof.Minimizing open space would negatively affect runoff - you need to maximize open space.Turf grass should be avoided because it requires more watering than native plants. Replacing plants with turf grass may have a negative effect, because turf grass may have more compact soil and not infiltrate as well.Question 24Show Answer Legend Which of the following causes depletion of the ozone layer?A PropaneB AmmoniaC CFCsD CO2Notes:Reference: Treatment by LEED of HVAC RefrigerantsCO2, ammonia, and propane are natural refrigerants that are not detrimental to the ozone layer.Question 25Show Answer Legend What type of water has the highest quality?A Waste waterB Process waterC Potable waterD Green waterNotes:Potable water is water that is suitable for drinking.Potable water is water that meets or exceeds EPA's drinking water standards andcomes from wells or the municipal water supply.Question 26Show Answer Legend Which of the following are counted as part of the buildable land area?A Public rights-of-wayB Public streetsC Areas with treesD Land excluded from residential development by lawNotes:Reference: LEED for Homes Rating System, Compact DevelopmentBuildable land is the portion of the site where construction can occur.

An urban heat island effect is caused by sunlight heatingup dark colored surfaces such as roads and rooftops. Huge quantities of heat are generated in buildings that have dark rooftops and absorb heat rather than reflectit.LEED defines a heat island as one whose temperatures are at least 10 degrees higher than those of surrounding suburban or rural areas.Question 28Show Answer Legend At what point can a project earn points for credits?A After the construction phaseB After the design phaseC After the LEED Scorecard is completed and submittedD After the statement of work has been uploaded to LEED OnlineNotes:No points can be earned after the design phase.Points may be marked as Anticipated in LEED Online after the design phase butpoints are only Achieved after the construction phase. This is true of all credits and prerequisites.Question 29Show Answer Legend Economic prosperity, environmental stewardship and social responsibility define a project's:A Triple bottom lineB InnovationC Minimum Program RequirementsD Federal, state, and/or local regulationsNotes:One of USGBC's Guiding Principles is to promote the Triple Bottom Line: 'USGBC will pursue robust triple bottom line solutions that clarify and strengthen a healthy and dynamic balance between environmental, social, and economic prosperity.'The triple bottom line (also known as 'people, planet, profit') captures an expanded spectrum of values and criteria for measuring organizational (and societal) success: economic prosperity, environmental stewardship and social responsibility.In practical terms, triple bottom line accounting means expanding the traditional reporting framework to take into account ecological and social performance inaddition to financial performance.'People, planet and profit' succinctly describes the triple bottom lines and thegoal of sustainability.Question 30Show Answer Legend Which of the following are strategies to reduce construction waste?A Give unused materials to a salvage yardB Use FSC certified materialsC Haul unused materials to a landfillD Select sustainable building materialsNotes:To reduce construction waste, divert any unused materials from the waste stream-namely, landfills and incinerators.Materials can be donated, sold, or recycled, to keep them out of landfills and tohelp reduce the demand for virgin materials.Question 31Show Answer Legend What environmental issue is associated with refrigerants used in HVAC&R systems?A Increasing greenhouse gas emissionsB Groundwater contaminationC Soil contaminationD Increased CO2 indoorsNotes:Reference: Treatment by LEED of HVAC RefrigerantsRefrigerants have ozone depletion potential (ODP) and global warming potential (GWP) due to greenhouse gas emissions. Low values of each are best for refrigerant choices.Question 32Show Answer Legend What information is needed to determine if a product will help with the heat island effect of a non-roof surface?A SRI of the materialB Life cycle costs of the materialC Run-off coefficients for the materialD Emissivity of materialNotes:Reference: LEED O+M Glossary:The heat island effect is created when developed areas have higher temperatures than surrounding rural areas. An urban heat island effect is caused by sunlight heatingup dark colored surfaces such as roads and rooftops. Huge quantities of heat are generated in buildings that have dark rooftops and absorb heat rather than reflectit.Many outdoor materials now come with the SRI value printed on the label sopurchasers know how the product will impact the urban heat island effect. The higher the SRI number the more solar heat the material can reflect. Black asphalt has anSRI of 0.LEED defines a heat island as one whose temperatures are at least 10 degrees higher than those of surrounding suburban or rural areas.LEED defines solar reflectance as: A measure of the ability of a surface materialto reflect sunlight-visible, infrared, and ultraviolet wavelengths-on a scale of 0to 1. Solar reflectance is also called albedo. Black paint has a solar reflectanceof 0; white paint (titanium dioxide) has a solar reflectance of 1.LEED defines solar reflectance index (SRI)as: A measure of a material's abilityto reject solar heat, as shown by a small temperature rise. Standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. For example, a standard black surface has a temperature rise of 90 degrees F (50 C) in full sun, and a standard white surface has a temperaturerise of 14.6 F (8.1 C). Once the maximum temperature rise of a given material has been computed, the SRI can be computed by interpolating between the values for white and black.Project teams do not need the emittance of a material. They do need the SRI valuebecause that is what is needed for the LEED credits. Emittance is used by manufacturers to calculate the SRI, but a project team doesn't need that info.Question 33Show Answer Legend The baseline water demand within a building includes the measurements of which ofthe following items?A Irrigation systemsB UrinalsC Cooling towersD Bathroom faucetsE ToiletsNotes:The baseline water demand within a building includes the measurement of fixtures and fittings (toilets, faucets). Toilets are measured in gallons per flush, whilefixtures are measured in gallons per minute.Question 34Show Answer Legend An office park design includes a parking lot. How could the parking be redesigned to reduce the heat island effect?A Designate preferred parking spacesB Encourage occupants to use public transportation one day a weekC Place the parking undergroundD Use black asphalt for the parking lotNotes:Moving a parking lot/spaces under the building is one way to reduce the heat island effect. This reduces the amount of impervious area above ground.The heat island effect is created when developed areas have higher temperatures than surrounding rural areas. An urban heat island effect is caused by sunlight heatingup dark colored surfaces such as roads and rooftops. Huge quantities of heat are generated in buildings that have dark rooftops and absorb heat rather than reflectit.LEED defines a heat island as one whose temperatures are at least 10 degrees higher than those of surrounding suburban or rural areas.Question 35Show Answer Legend How is ozone created?A A sunlight-driven chemical reaction between moleculesB Emissions from incineratorsC Emissions from factoriesD Transportation emissionsNotes:See the reference guide glossary entry for Ozone.Question 36Show Answer Legend A product's materials were extracted 300 miles from a project site, while theproduct was manufactured 600 miles from the project site. What statement is trueabout the product?A The product counts toward source reductionB The product is considered a locally harvested and manufactured materialC The product can count as a salvaged materialD The product does not count as a locally harvested and manufactured materialNotes:LEED gives credit when certain percentages of materials are extracted, harvested or recovered, and manufactured within 500 miles.In this example the material was extracted within 500 miles, but it wasnot manufactured within 500 miles. An example would be bricks where the materialused to make the bricks was extracted out of the ground 300 miles from the project site, but the bricks were baked 600 miles from the project site.Question 37Show Answer Legend In whole building design, at what starting point in the process would the facilities managers, end users, contractors, and architects all be involved at the same time?A Pre-designB Design phaseC Construction phaseD Pre-occupancyNotes:Reference: AIA Integrated Project DeliveryIn whole building design, all team members begin at the earliest point in thebuilding process to define common goals.Question 38Show Answer Legend Which items are considered pre-consumer recycled content?A Wood chips from a millB Soda cansC Cardboard boxesD Milk jugsNotes:Sawdust, shavings, and wood chips are pre-consumer material that can be used elsewhere, even if they are used for landscaping purposes.Question 39Show Answer Legend Who rules on CIRs?A Green RatersB Local USGBC ChapterC Technical Advisory GroupD LEED Standards BoardNotes:Make sure you understand what CIRs are and how they work:/DisplayPage.aspx?CMSPageID=142Also see Guidelines for CIR Customers from USGBC.There is no such thing as the LEED Standards Board.
