1.

Which strategy for indoor water reduction may be used only in WE Credit–Indoor Water Use Reduction? 

  • Using alternative water sources 

  • Using WaterSense labeled fixtures and fittings 

  • Using water efficient toilets and urinals 

  • Installing Energy Star dishwashers and washing machines

Correct answer: Using alternative water sources 

WE Prerequisite–Indoor Water Use Reduction does not allow project teams to use alternative water sources to achieve the initial 20% water use reduction. WE Credit–Indoor Water Use Reduction, however, does allow the use of alternate water sources as a strategy. 

Using WaterSense labeled fixtures and fittings, using water-efficient toilets and urinals, and installing Energy Star dishwashers and washing machines are strategies that can and should be used to achieve WE Prerequisite–Indoor Water Use Reduction. 

2.

 To earn points in LT Credit–Access to Quality Transit, how far from the building site can a streetcar stop be? 

  • Within a 1/4-mile (400-meter) walking distance 

  • Within a 1/3-mile (530-meter) walking distance 

  • Within a 1-mile (1,600-meter) walking distance 

  • Within a 1/2-mile (800-meter) walking distance 

Correct answer: Within a 1/4-mile (400-meter) walking distance 

To earn points in LT Credit–Access to Quality Transit, projects must be within a 1/4-mile (400-meter) walking distance of an existing or planned bus, streetcar, or rideshare stop or within a 1/2-mile (800-meter) walking distance of an existing or planned rapid transit bus stop, light or heavy rail station, commuter rail station, or commuter ferry terminal. 

Streetcars need to be within a 1/4-mile (400-meter) walking distance; heavier modes of transportation can be within a 1/2-mile (800-meter) walking distance. A 1-mile walking distance is too far to be counted, and a 1/3-mile walking distance is not used in this credit.

3.

 Which of the following LEED Neighborhood Development locations should a project avoid to be eligible for points in LT Credit–LEED for Neighborhood Development Location? 

  • LEED ND Pilot Stage 1 for Neighborhood Development Pre-reviewed Plan

  • LEED 2009 Stage 2 Pre-certified LEED for Neighborhood Development Plan

  • LEED ND Pilot Stage 3 LEED for Neighborhood Development Certified Project

  • LEED v4 Neighborhood Development Certified Built Project

Correct answer: LEED ND Pilot Stage 1 for Neighborhood Development Pre-reviewed Plan

Not all LEED Neighborhood Developments will earn project points in the Location and Transportation credit category. LEED ND Pilot Stage 1 for Neighborhood Development Pre-reviewed Plan, LEED 2009 Stage 1 Conditional Approval at LEED ND Plan, and LEED v4 LEED for Neighborhood Development Conditional Approval are not eligible locations for points in the Location and Transportation credit category. 

Building in locations with the LEED 2009 Stage 2 Pre-certified LEED for Neighborhood Development Plan, LEED ND Pilot Stage 3 LEED for Neighborhood Development Certified Project, or LEED v4 Neighborhood Development Certified Built Project, however, does provide opportunities to earn points in the Location and Transportation category. 

4.

EQ Credit–Thermal Comfort requires project teams to provide individual thermal comfort controls to at least 50% of individual occupant spaces. How should guest rooms in hospitality projects be counted in calculations? 

  • Guest rooms should not be included in credit calculations 

  • Guest rooms should be counted twice in credit calculations 

  • Only 50% of guest rooms should be included in credit calculations 

  • Only guest rooms should be included in credit calculations 

Correct answer: Guest rooms should not be included in credit calculations 

Guest rooms should already provide individual thermal comfort controls, so they should not be counted at all for this credit. 

Guest rooms definitely should not be counted twice.

5.

What is the minimum percentage of the project's energy that must be specified for provision from green power, carbon offsets, or renewable energy certificates in EA Credit–Green Power and Carbon Offsets?

  • 50%

  • 25%

  • 75%

  • 100%

Correct answer: 50% 

To earn EA Credit–Green Power and Carbon Offsets, project teams' green power, carbon offsets, or renewable energy certificate contract must specify that at least 50% or 100% of the project's energy is from any of the aforementioned sources.

Obtaining 25% of the project's energy from those sources would not meet this requirement. While 75% and 100% are excellent, they're not the minimum needed to earn points in this credit. 

6.

All of the following should be considered when choosing a site except:

  •  Lighting levels 

  • Building site attributes

  • Transportation

  • Occupant and community well-being

Correct answer: Lighting levels 

Lighting levels is not a site consideration. It is one of the options that projects can choose to assess in their simple box energy model analysis. The minimum site considerations include building site attributes, transportation, and occupant and community well-being.  

7.

What type of control systems should be in place for shared multi-occupant spaces according to EQ Credit–Interior Lighting? 

  • Multizone control systems that enable occupants to adjust lighting to group needs and preferences, with at least three lighting levels or scenes (on, off, midlevel)

  • Individual control systems for each occupant with remote access

  • Automated control systems that adjust lighting based on occupancy and daylight levels

  • Monitored control systems that enable building management to adjust the lighting levels remotely

Correct answer: Multizone control systems that enable occupants to adjust lighting to group needs and preferences, with at least three lighting levels or scenes (on, off, midlevel)

To earn EQ Credit–Interior Lighting, project teams must offer individual lighting controls for at least 90% of individual occupant spaces with at least three lighting levels (on, off, and midlevel). Midlevel is 30% to 70% of the maximum illumination level (not including daylight contributions). All multi-occupant spaces must have multizone control systems that enable occupants to adjust the lighting to meet group needs and preferences, including at least three lighting levels or scenes (on, off, midlevel). 

The controls do not need to be automated or monitored control systems for multi-occupant spaces, nor do individual controls need to be present for each occupant. 

8.

What is the required internal temperature range for occupation during flush-out?

  • At least 60°F (15°C) and no higher than 80°F (27°C)

  • At least 50°F (10°C) and no higher than 75°F (24°C)

  • At least 65°F (18°C) and no higher than 85°F (29°C)

  • At least 55°F (13°C) and no higher than 70°F (21°C)

Correct answer: At least 60°F (15°C) and no higher than 80°F (27°C)

EQ Credit–Indoor Air Quality Assessment, Path 2, is for project teams who want to perform a flush-out during occupancy. During this process, the team must maintain an internal temperature of at least 60°F (15°C) and no higher than 80°F (27°C) and relative humidity no higher than 60%.

9.

Which type of water system is the first choice for project teams wishing to use alternative sources of water?

  • Uses that require the least treatment

  • Uses that require water-type-specific treatment 

  • Uses that require a moderate level of treatment

  • Uses that require the most treatment

Correct answer: Uses that require the least treatment

Uses that require little to no treatment of the alternative water supply before it can be used are the most efficient option for project teams. 

Uses that require specific treatments or moderate to large amounts of treatment should not be the first choice for project teams. 

10.

What is the minimum required MERV rating that is acceptable according to IEQ Credit–Enhanced Indoor Air Quality Strategies? 

  • MERV 13

  • MERV 7

  • MERV 10

  • MERV 2

Correct answer: MERV 13

IEQ Credit–Enhanced Indoor Air Quality Strategies requires project buildings to have air filters with a minimum MERV rating of 13 or a Class F7 or higher. 

MERV ratings below 13 would not meet the minimum requirement for this credit. 

11.

What is the minimum average residential and nonresidential density to meet the requirements for Option 1: Density of LT Credit–Surrounding Density and Diverse Uses? 

  • Residential density must be at least 7 DU/acre (17.5 DU/hectare), and nonresidential density must be at least 0.5 FAR

  • Residential density must be at least 0.5 DU/acre (1.25 DU/hectare), and nonresidential density must be at least 7 FAR

  • Residential density must be at least 22,000 DU/acre (55,000 DU/hectare), and nonresidential density must be at least 35,000 FAR

  • Residential density must be at least 12 DU/acre (30 DU/hectare), and nonresidential density must be at least 0.8 FAR

Correct answer: Residential density must be at least 7 DU/acre (17.5 DU/hectare), and nonresidential density must be at least 0.5 FAR

Projects wanting to achieve Option 1: Density of LT Credit–Surrounding Density and Diverse Uses can calculate the density within a 1/4-mile (400-meter) radius of the project boundary using combined density or by using separate residential and nonresidential densities. The minimum requirement for residential density is 7 DU/acre (17.5 DU/hectare), and the minimum nonresidential density is 0.5 FAR. 

The next threshold for residential density, not the minimum, is 12 DU/acre. The next threshold for nonresidential density is 0.8 FAR. Projects that meet the next threshold get more points than those that meet the minimum.

12.

Project teams must demonstrate what percentage of energy improvement for EA Prerequisite–Minimum Energy Performance? 

  • 3%

  • 20%

  • 5%

  • 28%

Correct answer: 3%

Option 1 of EA Prerequisite–Minimum Energy Performance requires projects to demonstrate a 3% improvement in energy performance. 

The water consumption reduction from the baseline required for WE Prerequisite–Indoor Water Use Reduction is 20%. EA Credit–Optimize Energy Performance awards six points for a further 5% improvement in energy performance and 25 points for a 28% improvement in energy performance. 

13.

For a Cradle to Cradle Material Health certified product to qualify for MR Credit–Building Product Disclosure and Optimization–Material Ingredients, it must be at least Bronze level certified and have at least what percentage of materials assessed by weight? 

  • 90%

  • 100%

  • 50%

  • 70%

Correct answer: 90%

A qualified Cradle to Cradle Material Health certified product must be at least Bronze level certified and have at least 90% percent of materials assessed by weight. 

A product that has 100% of materials assessed by weight does qualify, but this is not the minimum. However, 50% or 70% of materials is too low to qualify according to the credit's requirements. 

14.

To qualify for EA Credit–Green Power and Carbon Offsets, the contract for the green power or carbon offset used by the project must be for at least how many years? 

  • Five years 

  • Three years 

  • Ten years 

  • One year

Correct answer: Five years 

A contract for green power or carbon offsets must cover at least five years of use, delivered annually. 

A contract that is for only one or three years would not qualify. Ten years is excellent but not the minimum. 

15.

Your project has a functional entrance within a 200-yard (180-meter) bicycling distance from a bicycle network that connects to an employment center. For the project to earn LT Credit–Bicycle Facilities, the employment center needs to be within what distance of the project boundary?

  • A 3-mile (4,800-meter) bicycling distance 

  • A 4-mile (6,437-meter) walking distance 

  • A 200-yard (180-meter) bicycling distance 

  • A 1/2-mile (800-meter) walking distance 

Correct answer: A 3-mile (4,800-meter) bicycling distance 

All destinations on the bicycle network must be within a 3-mile (4,800-meter) bicycling distance of the project boundary. 

A 4-mile (6,437-meter) bicycling distance is too far to meet this requirement, and the measurement must be bicycling distance, not walking distance. A 1/2-mile (800-meter) walking distance is used for LT Credit–Surrounding Density and Diverse Uses, not for LT Credit–Bicycle Facilities. A 200-yard (180-meter) bicycling distance is how far the project's functional entry needs to be from a bicycle network. 

16.

Environmental Product Declarations used in Option 1 of MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations must have at least which of the following?  

  • Cradle-to-gate scope 

  • Industry-wide (generic) EPD

  • Product-specific Type III EPD

  • FSC Certification 

Correct answer: Cradle-to-gate scope 

Environmental Product Declarations used in Option 1 of MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations must have at least cradle-to-gate scope. 

Products may have an industry-wide (generic) EPD or a product-specific Type III EPD, but neither is required by this credit. FSC (Forest Stewardship Council) Certification is required for wood products in MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials. 

17.

According to LEED requirements, a project's entire gross floor area must be certified under which of the following?

  • A single rating system

  • Up to two rating systems 

  • At least three rating systems 

  • No rating system is required, but it is highly recommended

Correct answer: A single rating system

Every LEED project must be certified under only one rating system. LEED projects cannot use more than one rating system per building.

18.

Which of the following is an appropriate alternative to potable water? 

  • Rainwater

  • Well water

  • Blackwater

  • Sea water

Correct answer: Rainwater

Rainwater is an excellent alternative to potable water. 

Well water, black water, sea water, and other untreated water sources are ineligible as potable water alternatives. 

19.

EQ Credit–Quality Views requires 75% of the building's regularly occupied floor area to have a direct line of sight to the outdoors. The occupants must have at least how many acceptable types of views? 

  • Two

  • Eight

  • Four

  • Six

Correct answer: Two

To earn points in EQ Credit–Quality Views, 75% of the building's regularly occupied floor area must have a direct line of sight to the outdoors using vision glazing. Additionally, these views must have at least two of the four acceptable types of views to earn this credit. 

There are only four types of acceptable views for this credit, and project teams are not required to have all four. 

20.

Which of the following credit categories offers project teams up to six points? 

  • Innovation

  • Regional Priority

  • Integrative process

  • Water Efficiency 

Correct answer: Innovation 

The Innovation category offers up to six points for projects. There are many ways to achieve these points, including having a LEED professional on the project, creating innovative strategies that are not touched on anywhere else in LEED, and trying a pilot credit. 

The Integrative Process category can earn projects up to one point. The Regional Priority category can earn projects up to four points. The Water Efficiency category can earn projects up to 11 points.
