Preliminary energy modeling focuses on the building's massing, orientation, thermal comfort ranges, and energy supply sources. Plug and process loads are typically omitted at this stage as they are highly variable and depend on specific occupant behavior and equipment usage. LEED focuses on the building's core energy performance during preliminary analysis.
NEW QUESTION # 44
Which of the following will contribute to reducing the heat island effect?
- A. Intensive vegetated roof
- B. Artificial turf grass
- C. Low sloped roof with initial Solar Reflectance Index (SRI) of 64
- D. Steep sloped roof with initial SRI of 35
Answer: A
Explanation:
An intensive vegetated roof is a roof that has a thick layer of soil and plants that provide shade, evapotranspiration, and stormwater management. It can reduce the heat island effect by lowering the surface and air temperature of the roof and the surrounding area. Artificial turf grass does not reduce the heat island effect because it is not a living plant and does not provide cooling benefits. A steep sloped roof with initial SRI of 35 does not meet the minimum requirement of 39 for Option 1 or 32 for Option 2 of the Heat Island Reduction credit. A low sloped roof with initial SRI of 64 exceeds the minimum requirement of 82 for Option
1 or 64 for Option 2, but it is not the best option among the choices because it only reflects solar radiation and does not provide other benefits such as shading, evapotranspiration, and stormwater management. References:

NEW QUESTION # 46
An owner has requested that the project team redesign a large office building. As part of the redesign, the owner would like to move the main entrance to the opposite side of the building. Achievement of which credit may be affected by the move?
- A. Location and Transportation Credit, Sensitive Land Protection
- B. Location and Transportation Credit, Surrounding Density and Diverse Uses
- C. Location and Transportation Credit, High-Priority Site
- D. Location and Transportation Credit, LEED for Neighborhood Development Location
Answer: B
Explanation:
Achievement of the Location and Transportation Credit, Surrounding Density and Diverse Uses may be affected by the move of the main entrance to the opposite side of the building. This is because the credit requires that the project be located within a minimum density area and within walking distance of diverse uses1. The walking distance is measured from a main functional entry of the project building to the diverse use entry1. If the main functional entry is moved, the distance to the diverse uses may change and affect the credit achievement. The other credits are not affected by the move of the main entrance, as they are based on the location of the project site, not the building entry. The Location and Transportation Credit, High-Priority Site rewards projects that are located on sites that are previously developed, infill, or adjacent to existing development2. The Location and Transportation Credit, Sensitive Land Protection rewards projects that are located on sites that do not contain sensitive land features such as prime farmland, wetlands, or habitats3. The Location and Transportation Credit, LEED for Neighborhood Development Location rewards projects that are located within the boundary of a LEED for Neighborhood Development certified plan4.

NEW QUESTION # 47
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. All alternative water sources should be treated to potable water standards
- B. Match uses by location: indoor sources to indoor uses, outdoor sources to outdoor uses
- C. Target the uses that require the least treatment first
- D. A project may not use two alternative water sources
Answer: C
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. References: WE Credit Indoor Water Use Reduction, WE Credit Outdoor Water Use Reduction, WE Credit Cooling Tower Water Use1

However, not all building types and sizes are covered by the AEDGs. According to the LEED Reference Guide for Building Design and Construction2, the following building types and sizes are eligible for this option:
* Small to Medium Office buildings up to 100,000 ft2 (9 290 m2)
* Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2)
* K-12 School buildings up to 200,000 ft2 (18 580 m2)
* Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2) Therefore, among the given options, only the school project is eligible to pursue this option, as it falls within the size limit for the K-12 School AEDG3.
NEW QUESTION # 51
A design team is working on a new building project and is employing an integrated, whole-building approach. The architects want to increase the size of a glazed opening on the south facing wall. Which team members are first affected by this change?
- A. Landscape architects
- B. Civil engineers
- C. Facility managers
- D. Mechanical engineers
Answer: D
Explanation:
According to the LEED v4: Building Design and Construction Guide, an integrated, whole-building approach is a process that requires collaboration and communication among all project team members and stakeholders throughout all phases of a project, from pre-design to occupancy and operations. The goal of this approach is to optimize the environmental and human health performance of a building as a whole, rather than focusing on individual components or systems1.
One of the benefits of an integrated, whole-building approach is that it allows the project team to identify and evaluate the interrelationships and trade-offs among various design strategies and decisions, and to optimize the synergies and minimize the conflicts among them1. For example, increasing the size of a glazed opening on the south facing wall may have implications for the daylighting, solar heat gain, thermal comfort, energy use, and mechanical system design of the building2. Therefore, the team members who are first affected by this change are the mechanical engineers, who are responsible for designing the heating, ventilation, and air conditioning (HVAC) system of the building, and ensuring that it meets the thermal comfort and energy performance requirements of the project3. The mechanical engineers may need to adjust the size, type, and location of the HVAC equipment, ductwork, and controls, as well as perform energy modeling and analysis to evaluate the impact of the change on the building's energy consumption and emissions3. The mechanical engineers may also need to coordinate with the architects, lighting designers, and other team members to ensure that the change does not compromise the other design goals and criteria of the project3.
