NEW QUESTION # 175
Which of the following should be analyzed when pursuing an Integrative Design Process focusing on Energy- Related Systems?
- A. Acoustic performance of the project
- B. Site conditions
- C. Applicability of Green Vehicles to the project
- D. Potable water availability
Answer: B
Explanation:
The correct answer is A, site conditions. According to the LEED v4: Building Design + Construction Guide, the Integrative Process Prerequisite, Integrative Project Planning and Design, requires the project team to perform a preliminary "simple box" energy modeling and analysis before the completion of schematic design.
The purpose of this analysis is to evaluate the energy performance goals of the project and to identify and compare the energy-related design strategies. The analysis should include the following aspects1:
* Site conditions, such as climate, solar orientation, shading, and natural ventilation potential
* Massing and orientation, such as building shape, size, and orientation, and how they affect the heating and cooling loads, daylight availability, and passive design strategies
* Basic envelope attributes, such as insulation levels, window-to-wall ratio, glazing properties, infiltration rates, and thermal bridging
* Lighting levels, such as the target illumination levels, daylighting potential, and lighting power density
* Plug and process loads, such as the equipment and appliances that consume electricity, and their schedules and controls
* Programmatic and operational parameters, such as the occupancy, operating hours, and zoning of the building
* Thermal comfort ranges, such as the acceptable temperature and humidity levels for the occupants
* HVAC system selection, such as the type, efficiency, and control of the heating, ventilation, and air conditioning system The other choices are not aspects that should be analyzed when pursuing an integrative design process focusing on energy-related systems, because:
* Potable water availability is related to the water efficiency and water quality goals of the project, not the energy performance goals2.
* Acoustic performance of the project is related to the indoor environmental quality and occupant comfort goals of the project, not the energy performance goals3.
* Applicability of green vehicles to the project is related to the location and transportation and greenhouse gas emissions goals of the project, not the energy performance goals4.

NEW QUESTION # 176
A tenant of a new office building will require 100 workstations per floor. Each floor will have two bathroom facilities and one conference room. How many lighting control devices with at least three lighting levels per floor are required to comply with Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control?
- A. 93 lighting control devices
- B. 91 lighting control devices
- C. 103 lighting control devices
- D. 100 lighting control devices
Answer: A
Explanation:
To comply with Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control, the tenant of a new office building will require 93 lighting control devices with at least three lighting levels per floor. This is because the credit requires that at least 90% of individual occupant spaces have lighting controls that enable occupants to adjust the lighting to suit their individual tasks and preferences1. The credit also requires that all shared multioccupant spaces have lighting controls that enable adjustments that meet the needs of the group1. According to the LEED BD+C Reference Guide, an individual occupant space is defined as an enclosed space or an open space that is occupied by one person and is at least 50 square feet (4.6 square meters) in area1. A shared multioccupant space is defined as an enclosed or open space that is occupied by more than one person and is at least 100 square feet (9.3 square meters) in area1.
Based on the given information, each workstation can be considered as an individual occupant space, and each bathroom facility and conference room can be considered as a shared multioccupant space. Therefore, the number of lighting control devices per floor can be calculated as follows:
For the 100 workstations, 90% of them need lighting controls, which is 90 workstations. Each workstation needs one lighting control device, so the total number of lighting control devices for the workstations is 90.
For the two bathroom facilities, each facility needs one lighting control device, so the total number of lighting control devices for the bathroom facilities is 2.
For the one conference room, one lighting control device is needed, so the total number of lighting control devices for the conference room is 1.
The total number of lighting control devices per floor is then 90 + 2 + 1 = 93.
NEW QUESTION # 177
In order to achieve Indoor Environmental Quality Credit, Quality Views the project team increased the window-to-wall ratio. Which prerequisite was impacted by this action?
- A. Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification
- B. Energy and Atmosphere Prerequisite, Fundamental Refrigerant Management
- C. Energy and Atmosphere Prerequisite, Building-Level Energy Metering
- D. Energy and Atmosphere Prerequisite, Minimum Energy Performance
Answer: D
Explanation:
Explanation
The correct answer isA. Energy and Atmosphere Prerequisite, Minimum Energy Performance. This is because:
* Increasing the window-to-wall ratio (WWR) would reduce the solar heat gain and the cooling load of the building, which are two of the main factors that affect the energy performance of a building12.
* The WWR is defined as the ratio of the area of windows to the area of external walls in a building3.The
* higher the WWR, the more natural light and ventilation can be achieved, which can improve the indoor environmental quality (IEQ) and reduce the need for artificial lighting and mechanical systems4.
* The LEED AP BD+C V4 credit for IEQ requires that buildings have a minimum WWR of 15% for south-facing walls and 20% for north-facing walls5.However, this minimum WWR may not be sufficient to achieve optimal IEQ in hot regions, where high solar radiation and humidity levels create high cooling demand6. Therefore, increasing the WWR beyond these minimum values can help achieve better IEQ by reducing both solar heat gain and cooling load.
* The other prerequisites are not impacted by increasing the WWR.Building-level energy metering is a prerequisite that requires measuring and reporting energy use at individual building units or zones5.Fundamental refrigerant management is a prerequisite that requires ensuring proper handling, storage, use, recovery, and disposal of refrigerants used in cooling systems5.Fundamental commissioning and verification is a prerequisite that requires ensuring that all commissioning activities are documented and verified according to LEED standards5.

NEW QUESTION # 178
For minimum acoustic performance, peak-hour is defined as M
- A. an energy-average of noise level divided by total sample time and area of the space
- B. highest noise level over various periods of time
- C. lowest noise level over a specified sample time
- D. an energy-average of the noise level over a specified sample time
Answer: B
Explanation:
Peak-hour is a term used to describe the time period when the traffic noise is highest, usually during morning and evening rush hours. Peak-hour noise level is measured by the equivalent continuous sound level (Leq), which is an energy-average of the noise level over a specified sample time. For minimum acoustic performance, LEED requires projects to implement acoustic treatment and other measures to minimize noise intrusion from exterior sources for high-noise sites (peak-hour Leq above 60 dBA during school hours).

This strategy preserves the embodied energy in the building materials, reducing the environmental impact of new material extraction, processing, and transportation, which is a core focus of LEED's sustainable building strategies.
NEW QUESTION # 181
Which strategy should be employed to improve daylighting when designing a new building?
- A. Increase the number of skylights
- B. Increase the building depth
- C. Increase the height of interior partitions
- D. Decrease the number of exterior light shelves
Answer: A
Explanation:
Increase the number of skylights
Skylights are openings in the roof or ceiling that allow natural light to enter the building. They can improve daylighting by providing more uniform and diffuse illumination, reducing the need for artificial lighting, and enhancing the visual comfort and well-being of occupants. Skylights can also reduce cooling loads by minimizing solar heat gain through the roof. However, skylights must be designed carefully to avoid glare, overheating, and heat loss issues.

NEW QUESTION # 182
A building owner installs a building automation system (BAS) to allow programmable load control. Which of the following credits can be pursued because of the installation?
- A. Energy and Atmosphere Credit, Demand Response
B Energy and Atmosphere Credit, Ongoing Commissioning - B. Energy and Atmosphere Credit, Enhanced Refrigerant Management
- C. Energy and Atmosphere Credit, Enhanced Commissioning
Answer: A
Explanation:
This is because:
* A building automation system (BAS) is a system that controls and monitors various aspects of a building's operation, such as lighting, heating, ventilation, air conditioning, security, fire alarm, and energy management1.
* A BAS can allow programmable load control (PLC), which is the ability to adjust the power consumption of devices or equipment based on a schedule, a sensor, or an event2. PLC can help reduce the energy demand and cost of a building by optimizing the use of resources and avoiding unnecessary or wasteful consumption3.
* The LEED AP BD+C V4 credit for Demand Response requires that buildings have a demand response program that can respond to changes in electricity prices or supply by reducing or shifting the demand for electricity4. A BAS can enable such a program by allowing PLC and other features that can modulate the power usage of devices or equipment in response to market signals or internal conditions.
Therefore, installing a BAS to allow PLC can help achieve the Energy and Atmosphere Credit for Demand Response by reducing the energy demand and cost of a building.

NEW QUESTION # 184
A project attempting to meet the preferred parking requirements for Location and Transportation Credit, Green Vehicles may provide what incentive to meet the requirements and highlight the project sustainable vehicle strategy?
- A. Three years of free parking for green vehicles
- B. Preferred parking decals for 5% of occupants utilizing carpool vehicles
- C. An annual maintenance voucher for at least 5% of occupants driving green vehicles
- D. A permanent discounted parking rate of at least 20% for all green vehicles
Answer: D
Explanation:
Explanation
The Location and Transportation Credit, Green Vehicles aims to reduce transportation-related greenhouse gas emissions by promoting the use of low-emitting, fuel-efficient, and alternative-fuel vehicles1. One of the requirements for this credit is to provide preferred parking for green vehicles for 5% of the total vehicle parking capacity of the project1. Preferred parking is defined as parking that is clearly marked and located in the most convenient spaces available to the driver or nearest to the main entrance of the project2. In addition to providing preferred parking, the project may also offer one or more incentives to encourage the use of green vehicles, such as a discounted parking rate, free parking passes, or rebates for parking fees3. The question asks what incentive may be provided to meet the requirements and highlight the project sustainable vehicle strategy. The correct answer is C. A permanent discounted parking rate of at least 20% for all green vehicles, because this incentive meets the minimum threshold of 20% discount suggested by the LEED Reference Guide for Building Design and Construction3, and it also demonstrates the project's commitment to supporting green vehicles in the long term. The other options are either not sufficient or not relevant for this credit. Option A.
Three years of free parking for green vehicles is not sufficient because it is not permanent and may not be attractive enough for drivers to switch to green vehicles. Option B. Preferred parking decals for 5% of occupants utilizing carpool vehicles is not relevant because it does not address green vehicles, but rather carpool vehicles, which are covered by a different credit (Location and Transportation Credit, Reduced Parking Footprint)4. Option D. An annual maintenance voucher for at least 5% of occupants driving green vehicles is not sufficient because it is not directly related to parking and may not be a significant incentive for drivers.

In pursuit of the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices, which of the following statements is true related to products purchased for temporary use (formwork, bracing and scaffolding) on the project?
- A. If any temporary wood materials are included in the calculation, all wood materials must be included in the calculation
- B. Only Forest Stewardship Council (FSC)-certified wood materials are included in the calculation; non-certified wood materials contribute to other credits
- C. Temporary wood products cannot be included in the calculations
- D. FSC-certified wood materials purchased for more than one project can be applied to other projects seeking LEED Certification
Answer: C
Explanation:
Explanation
Temporary wood products cannot be included in the calculations for the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices.
This is because the credit only applies to permanently installed building products, not to products purchased for temporary use on the project1. The other options are false. If any temporary wood materials are included in the calculation, they must be excluded from the total value of permanently installed building products1.
Non-certified wood materials do not contribute to other credits, unless they meet other criteria such as recycled content or regional materials2. FSC-certified wood materials purchased for more than one project cannot be applied to other projects seeking LEED certification, unless they are reused or salvaged materials3.

- A. Pilot Credit feedback surveys must be completed
- B. A registered Pilot Credit must be replaced on the LEED project's scorecard if that pilot credit is removed from the Pilot Credit Library
- C. Pilot Credits can be attempted in the design review stage only
- D. Pilot Credits are not specific to the rating systems
Answer: A
Explanation:
One of the requirements for attempting a pilot credit is to complete a feedback survey after submitting the project for review. The LEED v4 Reference Guide for Building Design and Construction states that "the project team must complete a feedback survey for each pilot credit attempted. The survey link is provided in the pilot credit language. The survey must be completed after the project has been submitted for review and before the project receives a final rating"1. The feedback survey is an important tool for USGBC to evaluate the effectiveness and applicability of the pilot credit, and to make improvements or modifications based on the project team's experience.

- A. Energy and Enhanced Commissioning
- B. Energy and Atmosphere, Optimize Energy Performance
- C. Indoor Environmental Quality, Thermal Comfort
- D. Indoor Environmental Quality, Interior Lighting
Answer: B
Explanation:
While increased ventilation improves indoor air quality, it can also lead to higher energy consumption, impacting LEED BD+C Energy and Atmosphere (EA) Credit: Optimize Energy Performance.
* More ventilation requires more heating/cooling energy, which can increase energy use and reduce overall energy efficiency.
* This can lower the points earned for energy optimization, since LEED rewards projects that minimize energy consumption.
* Other credits (Options A, B, and D) are not directly affected by increased ventilation rates.
Energy performance is negatively impacted when additional ventilation leads to increased HVAC energy demand.

Rainwater collected from the building roof would be the most appropriate nonpotable water source for use in a cooling tower. This is because rainwater is generally cleaner than other nonpotable sources and does not require extensive treatment before use. Additionally, using rainwater can help to reduce stormwater runoff, providing an additional environmental benefit.
NEW QUESTION # 191
Which one of the following represents quality transit service as defined in Location and Transportation Credit, Access to Quality Transit?
- A. A private shuttle bus stop providing hourly service Monday through Friday to a rail station two hours away, located across the street from the project building
- B. A rail station served by two train lines Monday through Sunday, located 1 mi. (1.60 km) from the project building
- C. A bus stop served by two bus lines Monday through Friday, located 1/8 mi. (0.20 km) from the project building
- D. A rail station served by one train line Monday through Sunday, located 1/2 mi. (0.80 km) from the project building
Answer: D
Explanation:
The Location and Transportation Credit, Access to Quality Transit requires projects to locate within walking distance of existing or planned transit stops that provide access to quality transit service1. Quality transit service is defined as transit service that meets the minimum weekday and weekend headways (time between vehicles) and hours of operation listed in Table 1 of the credit requirements2. According to Table 1, the minimum weekday headway for bus service is 15 minutes, and the minimum weekday headway for rail service is 10 minutes. The minimum weekend headway for both bus and rail service is 30 minutes. The minimum hours of operation for both bus and rail service are 6 a.m. to 8 p.m. on weekdays and 8 a.m. to 6 p.
m. on weekends2. In addition, the credit requires projects to locate within a 1/4 mi. (0.40 km) walking distance of bus, streetcar, or rideshare stops or within a 1/2 mi. (0.80 km) walking distance of bus rapid transit stops, light or heavy rail stations, commuter rail stations, or ferry terminals1.
Option A does not represent quality transit service because it only has two bus lines that may not meet the minimum headway and hours of operation requirements. Option C does not represent quality transit service because it is beyond the maximum walking distance of 1/2 mi. (0.80 km) for rail stations. Option D does not represent quality transit service because it is a private shuttle bus that does not qualify as a public transportation service, and it provides hourly service that does not meet the minimum headway requirements.
Option B represents quality transit service because it has a rail station that is within the maximum walking distance of 1/2 mi. (0.80 km) from the project building, and it has one train line that operates Monday through Sunday, which implies that it meets the minimum headway and hours of operation requirements.
