A ferry service or commuter rail that is within 1/2 mile (800 meters) of a functional entrance must provide at least how many trips to qualify for points in LT Credit–Access to Quality Transit? 

  • 24 weekday trips and six weekend trips 

  • 40 weekday trips and eight weekend trips 

  • 20 weekday trips and four weekend trips 

  • 72 weekday trips and 40 weekend trips 

Correct answer: 24 weekday trips and six weekend trips 

Commuter rail and ferry services must offer a minimum of 24 weekday trips and six weekend trips to qualify for points. Transit services that meet these minimums will earn projects one point. 

Commuter rail and ferry services that provide 40 weekday and eight weekend trips meet the next threshold, not the minimum, and give projects two points. Those that provide 20 weekday trips and four weekend trips do not have enough trips to qualify for points. Commuter rail and ferry services offering 72 weekday trips and 40 weekend trips provide projects with three points; however, these are not the minimum numbers of trips. 

162.

A project team uses 20 different permanently installed products that have reports from their raw material suppliers, but to qualify for MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials, how many different manufacturers must those products come from? 

  • At least five different manufacturers 

  • At least three different manufacturers 

  • At least ten different manufacturers 

  • At least 15 different manufacturers 

Correct answer: At least five different manufacturers 

MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials, Option 1, requires project teams to use at least 20 different permanently installed products from at least five different manufacturers that have publicly available reports on their raw material suppliers.

Using 20 different products from 10 or 15 manufacturers would qualify the project for this credit, but this is not the minimum required to earn points. Products from only three different manufacturers would not qualify for points. 

163.

Reviewing the ANSI Consensus National Standard Guide would help project teams with which of the following? 

  • Integrative Process 

  • Materials and Resources

  • Location and Transportation 

  • Regional Priority 

Correct answer: Integrative Process 

The ANSI Consensus National Standard Guide is the standard used for IP Credit–Integrative Process. 

This guide is not used in Materials and Resources, Location and Transportation, or Regional Priority. 

164.

What is the minimum percentage of construction and demolition materials required to be diverted for Option 1, Path 1 of MR Credit–Construction and Demolition Waste Management?

  • 50%

  • 75%

  • 100%

  • 30%

Correct answer: 50%

Option 1, Path 1 of MR Credit–Construction and Demolition Waste Management requires projects to divert at least 50% of their total construction and demolition material. These diverted materials must include at least three material streams. 

The requirement for Path 2 of Option 1 for this credit is diversion of 75%. Diverting 100% is not required but is an excellent achievement. Diverting 30% would not meet the minimum requirement for this credit. 

165.

Which of the following uses a purple pipe to distinguish it from other water sources? 

  • Reclaimed water

  • Gray water

  • Black water

  • Potable water

Correct answer: Reclaimed water

Municipally supplied reclaimed water is labeled with purple piping to warn users that water from these pipes is not potable. While it cannot be used for drinking and cooking, it can be used in toilets, irrigation systems, etc. 

Gray water and black water are types of water that have been used and then discarded. Gray water has been used in laundry machines, bathtubs, showers, and bathroom sinks, and it may be transported in purple pipes if it's being reclaimed.

Black water has come into contact with human waste; this is usually water from toilets. However, water from kitchen sinks can sometimes be considered black water due to having contact with meat. Black water can be reclaimed only after extensive treatment.

Potable water is acceptable for drinking; purple piping is used to warn people not to drink the water because it is not potable. 

166.

A project with 5% of renewable energy use earns how many points in EA Credit–Renewable Energy Production? 

  • Three points 

  • Two points 

  • One point 

  • Five points 

Correct answer: Three points 

A project with 5% of renewable energy use or ownership would earn a project three points, which is the maximum number of points in this credit. 

A project with 1% earns one point, and 3% earns two points. This credit does not award five points. 

167.

For a team to choose LEED ID+C: Core and Shell, how much of the interior must be complete at the time of certification? 

  • 60%

  • 50%

  • 40%

  • 30%

Correct answer: 60% 

To qualify for LEED ID+C: Core and Shell, project interiors must be at least 60% complete by the time of certification. 

Interiors that are 50%, 40%, or 30% complete by the time of certification do not meet the requirement for ID+C. 

168.

Which of the following is not a rating system for LEED ID+C?  

  • ID+C: Schools 

  • ID+C: Commercial Interiors 

  • ID+C: Retail

  • ID+C: Hospitality 

Correct answer: ID+C: Schools 

The rating systems in LEED ID+C include ID+C: Hospitality, ID+C: Retail, and ID+C: Commercial Interiors. There is no ID+C: Schools rating system.

169.

What is the minimum percentage of construction and demolition materials required to be diverted for Option 1, Path 2 of MR Credit–Construction and Demolition Waste Management to earn two points?

  • 75%

  • 50%

  • 100%

  • 30%

Correct answer: 75%

Option 1, Path 2 of MR Credit–Construction and Demolition Waste Management requires projects to divert at least 75% of their total construction and demolition material to earn two points. These diverted materials must include at least four material streams. 

Diverting 50% is the requirement to earn one point for Path 1 of Option 1 for this credit. Diverting 100% is not required but is an excellent achievement. Diverting 30% would not meet the minimum requirement of this credit. 

170.

 Which of the following credits or prerequisites would a project team be attempting by assessing the basic envelope attributes and site conditions of the project? 

  • IP Credit–Integrative Process

  • EA Credit–Optimize Energy Performance

  •  EA Prerequisite–Fundamental Commissioning and Verification

  • MR Credit–Long-Term Commitment 

Correct answer: IP Credit–Integrative Process

Teams hoping to achieve IP Credit–Integrative Process are required to do a simple box energy model analysis. Teams must choose at least two of six applicable aspects of the project. 

Based on the assessments being made, the project is not attempting MR Credit–Long-Term Commitment, EA Credit–Optimize Energy Performance, or EA Prerequisite–Fundamental Commissioning and Verification in the scenario. 

171.

What is the second phase in the integrative process?

  • Design and construction

  • Occupancy

  • Discovery

  • Operation

Correct answer: Design and construction

The design and construction phase comes after the discovery phase. The design and construction phase is when the data and strategies formed in the discovery phase are put into practice. 

Occupancy comes after the design and construction phase. There is no operation phase.

172.

What is one method used to gather feedback regarding occupants' satisfaction?

  • Surveys and data collection

  • Review of utility bills

  • Building audits

  • Evaluation of lighting levels

Correct answer: Surveys and data collection

It's important to receive feedback from occupants about their experience in the building. LEED project teams do this by sending out surveys and collecting data. 

Reviewing bills and conducting building audits will help give an idea of energy consumption, but not of occupant satisfaction. Evaluating lighting levels and optimizing them for occupant comfort may improve occupant satisfaction, but only by collecting feedback can project teams be sure that their occupants are satisfied. 

173.

To comply with MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials, wood products must be certified by which entity?

  • Forest Stewardship Council

  • LEED Certification

  • Green Seal Certification

  • USGBC Certification

Correct answer: Forest Stewardship Council

To comply with requirements in MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials, wood products must be certified by the Forest Stewardship Council. 

LEED Certification is for buildings. Green Seal Certification allows project teams to identify lead- and cadmium-free paints. There is no such thing as the USGBC Certification. 

174.

Which type of building is not eligible for LEED certification?

  • Movable building

  • Permanent building

  • A building that meets the rating system size requirement 

  • A project with reasonable LEED boundaries 

Correct answer: Movable building

Movable buildings are ineligible for LEED certification. 

Permanent buildings, buildings that meet rating system size requirements, and projects with reasonable LEED boundaries meet the LEED MPRs and qualify for certification. 

175.

A project team has fulfilled the first requirement of MR Prerequisite–Storage and Collection of Recyclables by recycling the required materials. To fulfill the second part of the requirements, they must choose two more materials to recycle. Which of the following is an appropriate choice? 

  • Batteries and mercury-containing lamps

  • Glass and plastics

  • Paper and cardboard

  • Metals and e-waste

Correct answer: Batteries and mercury-containing lamps

For MR Prerequisite–Storage and Collection of Recyclables, commercial interiors and hospitality projects must recycle mixed paper, corrugated cardboard, glass, plastics, and metals. Projects must also choose two of the following to collect: e-waste, mercury lamps, and batteries. 

176.

 What range of points should a project team aim for to achieve LEED Silver?

  • 50–59

  • 60–69

  • 40–49

  • 79–80

Correct answer: 50–59 

To achieve the second level of LEED certification, LEED Silver, projects should aim to earn anywhere from 50 to 59 points. Projects earning 40–49 points achieve LEED Certified, while those earning 60–79 points achieve LEED Gold and those earning 80+ points achieve LEED Platinum.

177.

Which of the following is the default gender ratio for full-time-equivalent occupants? 

  • 50:50

  • 90:10

  • 30:60

  • 70:20

Correct answer: 50:50

The default gender ratio, which is appropriate for most projects, is 50:50. Projects with special circumstances, such as single-gender schools, must provide a narrative and supporting documentation justifying the use of an alternative ratio. 

Other ratios, such as 30:60, 90:10, and 70:20, are not defaults and should not be used for most projects. Projects with special circumstances, however, may need to use alternative gender ratios such as these. 

178.

Your project team is using Option 1: Whole Building Energy Simulation for EA Prerequisite–Minimum Energy Performance and is calculating their baseline and savings. Your building has many unregulated loads. How should your team calculate the savings from this equipment into the baseline and why? 

  • By using the Exceptional Calculation Method (ECM) because these are unregulated loads

  • These shouldn't be included in calculations because they are unregulated loads

  • By using ASHRAE 50% Advanced Energy Design Guides because these guides don't have any requirements for unregulated loads

  • By using the Core Performance Guide to calculate these loads because the guide defines unregulated loads

Correct answer: By using the Exceptional Calculation Method (ECM) because these are unregulated loads 

ECM is used in ASHRAE 90.1 and LEED v4. It specializes in calculating the savings for unregulated loads, such as copiers, computers, and elevators. 

Unregulated loads should be included in calculations for this credit. ASHRAE 50% Advanced Energy Design Guides and the Core Performance Guide are used in the other options for this credit. 

179.

Which of the following is not listed as a possible alternative to potable water? 

  • Black water

  • Gray water

  • Rainwater

  • Used process water

Correct answer: Black water

Black water is water that has come into contact with human waste. It's not safe to use as an alternative water source without extensive treatment. 

Used process water has been used in manufacturing processes. Gray water has been used in laundry machines, bathroom sinks, showers, and bathtubs. Rainwater, gray water, and used process water are all excellent alternatives to potable water for some purposes. 

180.

For a flush-out performed during occupancy, what is the minimum rate of ventilation required once the space is occupied?

  • 0.30 cubic feet per minute (cfm) per square foot of outdoor air (1.5 liters per second per square meter of outdoor air)

  • 0.20 cubic feet per minute (cfm) per square foot of outdoor air (1.0 liters per second per square meter of outdoor air)

  • 0.45 cubic feet per minute (cfm) per square foot of outdoor air (2.25 liters per second per square meter of outdoor air)

  • 0.60 cubic feet per minute (cfm) per square foot of outdoor air (3.0 liters per second per square meter of outdoor air)

Correct answer: 0.30 cubic feet per minute (cfm) per square foot of outdoor air (1.5 liters per second per square meter of outdoor air)

EQ Credit–Indoor Air Quality Assessment, Path2, is for project teams who want to perform a flush-out during occupancy. First, the project must deliver a minimum of 3,500 cubic feet of outdoor air per square foot (1,066,260 liters of outdoor air per square meter) before occupancy. Then, once the building is occupied, this path requires a minimum ventilation rate of 0.30 cubic feet per minute (cfm) per square foot of outdoor air (1.5 liters per second per square meter of outdoor air) to complete the process.
