NEW QUESTION # 100
A project team has installed a rainwater harvesting system on site. In which of the following could this system be recognized?
- A. Sustainable Sites Credit, Rainwater Management and Water Efficiency Credit, Indoor Water Use Reduction
- B. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Indoor Water Use Reduction
- C. Sustainable Sites Credit, Rainwater Management and Water Efficiency Prerequisite, Indoor Water Use Reduction
- D. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Outdoor Water Use Reduction
Answer: A
Explanation:
Explanation
A rainwater harvesting system on site could be recognized in the Sustainable Sites Credit, Rainwater Management and the Water Efficiency Credit, Indoor Water Use Reduction. The Sustainable Sites Credit, Rainwater Management rewards projects that reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. A rainwater harvesting system can help achieve this by capturing and reusing rainwater on site2. The Water Efficiency Credit, Indoor Water Use Reduction rewards projects that reduce indoor water consumption by installing water-efficient fixtures and fittings3. A rainwater harvesting system can help achieve this by providing an alternative source of water for non-potable uses such as toilet flushing and irrigation4.
The other options are not correct. The Water Efficiency Credit, Water Metering does not recognize rainwater harvesting systems, but rather requires projects to install permanent water meters that measure the total potable water use for the building and grounds. The Water Efficiency Prerequisite, Outdoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce outdoor water consumption by using plant species that are native or adapted to the region and by using irrigation systems that are efficient and properly controlled. The Water Efficiency Prerequisite, Indoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce indoor water consumption by 20% from the baseline by installing water-efficient fixtures and fittings.

NEW QUESTION # 103
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 design to reduce the amount of roofing area
- C. Increase the parapet height
- D. Change the roofing material to a dark material to eliminate the issue
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 # 104
Which of the following is a leadership extraction practice that rewards projects for choosing materials with closed-loop recycling and take-back programs in LEED?
- A. Extended producer responsibility
- B. Material reuse
- C. Bio-based elements
- D. Forest Stewardship Council (FSC) wood products
Answer: A
Explanation:
Explanation
Extended producer responsibility
Extended producer responsibility is a leadership extraction practice that encourages manufacturers to take back their products or packaging at the end of their useful life and recycle them in a closed-loop system. This reduces the environmental impacts of extraction, transportation, and disposal of raw materials. LEED rewards projects for choosing materials that have extended producer responsibility programs or policies in place.

NEW QUESTION # 108
A new five-story building with a 30,000 ft2 (2 800 m2) footprint is being designed on a previously disturbed100,000 ft2 (9 290 m2) site. The remaining on-grade surface will be 35,000 ft2 (3 250 m2) of asphalt parking, and 35,000 ft2 (3 250 m2) of native vegetated open space. To achieve a point for exemplary performance under Option 1 of Sustainable Sites Credit, Site Development - Protect or Restore Habitat, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of
- A. 15,000 ft2 (1 400 m2)
- B. 25,000 ft2 (2 300 m2)
- C. 35,000 ft2 (3 250 m2)
- D. 12,500 ft2 (1 160 m2)
Answer: B
Explanation:
Explanation
According to the LEED v4 Reference Guide for Building Design and Construction, Option 1 of the Site Development - Protect or Restore Habitat credit requires restoring 25% of the site area (including the building footprint) with native or adapted vegetation1. To achieve exemplary performance, the project must double the credit requirements and restore 50% of the site area2. In this case, the site area is 100,000 ft2 (9 290 m2), so the project must restore 50,000 ft2 (4 645 m2) with vegetation. The project already has 35,000 ft2 (3 250 m2) of native vegetated open space, so it needs to add another 15,000 ft2 (1 395 m2) of vegetation. Since the on-grade surface is fully occupied by the building footprint and the asphalt parking, the only option is to incorporate a vegetated roof. Therefore, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of 15,000 ft2 (1 395 m2).

NEW QUESTION # 110
A developer is considering an urban infill site for a new commercial building rather than a rural greenfield site adjacent to a stream. Which of the following is an economic advantage of the infill site?
- A. Reduces need for new utility infrastructure
- B. Preserves habitat and natural resources
- C. Protects greenfields and farmland
- D. Reduces potential damage to an existing stream
Answer: A
Explanation:
Explanation
An economic advantage of the infill site is that it reduces the need for new utility infrastructure. This is because the infill site is located within an existing urban area that already has access to water, sewer, electricity, and other utilities1. The developer can save on the costs of extending or installing new utility lines and services to the rural greenfield site, which may not have adequate or reliable utility infrastructure2. The other options are not economic advantages, but rather environmental benefits of the infill site. Protecting greenfields and farmland, preserving habitat and natural resources, and reducing potential damage to an existing stream are all positive outcomes of avoiding development on the rural greenfield site, but they do not directly translate into monetary savings for the developer3.

NEW QUESTION # 111
During a review of the HVAC equipment submittal, the Commissioning Authority (CxA) determined that the contractorsubstituted a higher efficiency piece of equipment. Which of the following is the priority for the CxA to consider?
- A. Equipment Maintenance Plan
- B. Coordination of other contractors
- C. Energy meter location
- D. Owner's Project Requirements
Answer: D
Explanation:
Explanation
The Owner's Project Requirements (OPR) is a document that defines the goals, expectations, and performance criteria of the project, as established by the owner or the owner's representative1. The OPR is one of the key deliverables of the commissioning process and serves as the basis for the design, construction, and operation of the building systems. Therefore, the priority for the Commissioning Authority (CxA) to consider when the contractor substitutes a higher efficiency piece of equipment is whether the substitution meets or exceeds the OPR. The CxA should verify that the new equipment is compatible with the OPR and does not compromise the performance, functionality, or reliability of the system. The CxA should also communicate the substitution to the owner and the design team and document the change in the commissioning plan and report.

NEW QUESTION # 120
A facility manager cleaning highly reflective paving material is
- A. lowering the Solar Reflectance Index (SRI)
- B. unnecessarily wasting water
- C. increasing the heat island effect
- D. reducing the heat island effect
Answer: D
Explanation:
Explanation
The heat island effect is the phenomenon of urban areas having higher air temperatures than surrounding rural areas due to the absorption and emission of heat by human-made surfaces, such as buildings, roads, and pavements. The heat island effect can have negative impacts on theenvironment, human health, and energy consumption. One of the strategies to reduce the heat island effect is to use highly reflective paving materials that have a high solar reflectance index (SRI), which measures the ability of a surface to reflect solar radiation and stay cool. However, over time, the paving materials can accumulate dirt and dust, which can lower their reflectance and increase their heat absorption. Therefore, a facility manager cleaning highly reflective paving material is reducing the heat island effect by restoring the reflectance and cooling potential of the surface12.
