NEW QUESTION # 130
In the energy modeling of a building envelope, which of the following U-values should be considered as an assembly U-value?
- A. Concrete
- B. Steel
- C. Glass
- D. Wall
Answer: D
Explanation:
Explanation
The assembly U-value of a building envelope component is the overall rate of heat transfer through that component, taking into account the different materials and layers that make up the component. For example, the assembly U-value of a wall would include the effects of the insulation, framing, sheathing, cladding, air films, etc. The assembly U-value is different from the material U-value, which is the rate of heat transfer through a single material. For example, the material U-value of steel is much higher than the material U-value of glass, but the assembly U-value of a steel-framed window may be lower than the assembly U-value of a glass curtain wall, depending on the other factors involved.

NEW QUESTION # 132
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. 100 lighting control devices
- B. 91 lighting control devices
- C. 93 lighting control devices
- D. 103 lighting control devices
Answer: C
Explanation:
Explanation
To comply with Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control, the tenant of a new office building will require93 lighting control deviceswith 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 # 135
During a design charrette, community neighbors raise a concern about potential glare resulting from a project's highlyreflective roof. Which option should the LEED AP recommend to best address these concerns?
- A. Install a vegetative roofing system
- B. Change the roofing material to a dark material to eliminate the issue
- C. Increase the parapet height
- D. Change the design to reduce the amount of roofing area
Answer: A
Explanation:
Explanation
Installing a vegetative roofing system is the best option to address the potential glare resulting from a project's highly reflective roof. A vegetative roofing system, also known as a green roof, is a roof that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. A vegetative roofing system can reduce the reflectivity of the roof surface and mitigate the glare impact on the surrounding environment. It can also provide other benefits, such as reducing heat island effects, improving stormwater management, enhancing biodiversity, and increasing roof insulation. Therefore, option A is the correct answer. The other options are not as effective or desirable as installing a vegetative roofing system.
Changing the design to reduce the amount of roofing area (option B) may not be feasible or desirable, as it may compromise the project's program or performance. Changing the roofing material to a dark material to eliminate the issue (option C) may reduce the glare, but it will also increasethe heat absorption and emission of the roof, contributing to heat island effects and increasing cooling loads. Increasing the parapet height (option D) may block some of the glare, but it will also increase the material and construction costs, and it may not be sufficient to prevent glare from all angles.For more information on vegetative roofing systems and their benefits, you can refer to the LEED v4 Reference Guide for Building Design and Construction1or the Green Roofs for Healthy Cities website2.

NEW QUESTION # 141
What is the basis of energy consumption in determining the percentage of green power or carbon offsets?
- A. Efficiency
- B. Quantity
- C. Quality
- D. Performance
Answer: B
Explanation:
Explanation
The basis of energy consumption in determining the percentage of green power or carbon offsets is the quantity of energy used by the project, measured in kilowatt-hours (kWh) or British thermal units (Btu). Green power is electricity generated from renewable sources, such as solar, wind, hydro, biomass, or geothermal.
Carbon offsets are reductions or removals of greenhouse gas emissions from a project or activity that compensates for theemissions from another source. According to the LEED Reference Guide for Building Design and Construction1, the Energy and Atmosphere Credit, Green Power and Carbon Offsets, requires the project to engage in a contract for qualified resources that meet the following requirements:
* The contract term is at least five years.
* The green power or carbon offsets are based on the quantity of energy consumed by the building.
* The green power is Green-e Energy certified or the equivalent.
* The carbon offsets are Green-e Climate certified, Verified Carbon Standard certified, Gold Standard certified, or the equivalent.

NEW QUESTION # 142
A project has a potable water source as well as two alternative water sources. Which of the following statements is applicable for a project using two alternative water sources?
- A. Match uses by location: indoor sources to indoor uses, outdoor sources to outdoor uses
- B. All alternative water sources should be treated to potable water standards
- C. A project may not use two alternative water sources
- D. Target the uses that require the least treatment first
Answer: D
Explanation:
Explanation
The best practice for using alternative water sources is to target the uses that require the least treatment first, such as irrigation, toilet flushing, and cooling tower makeup. This reduces the energy and cost associated with treating water to higher standards than necessary. Matching uses by location is not a requirement, nor is treating all alternative water sources to potable water standards. A project may use more than one alternative water source as long as they meet the applicable codes and standards.
