• Question 283:

  The maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are

  A. 8
  B. 10
  C. 12
  D. 16
  D. 16

  ---

  The LEED for Neighborhood Development rating system has four certification levels: Certified, Silver, Gold, and Platinum. Each level requires a minimum number of points to achieve, based on the total number of available points in the rating system..The total number of available points is 110, and the minimum points for Platinum certification is 801. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 110 - 80 = 30 points..However, there are also four regional priority credits that can be earned for addressing geographicallyspecific environmental issues2. These credits are worth one point each, and can be added to the total score of a project. Therefore, the maximum possible points a new construction platinum LEED for Neighborhood Development certification level can earn are 30 + 4 = 34 points. However, the question asks for the maximum points that can be earned by a.new construction.project..According to the LEED Reference Guide for ND, new construction projects must meet all prerequisites and achieve at least 50% of the points available under the Green Infrastructure and Buildings category3..This category has 21 criteria, each worth one point, except forCertified Green Buildings, which is worth up to five points4. Therefore, the maximum points available under this category are 21 + 4 = 25 points. Since new construction projects must achieve at least 50% of these points, they must earn at least 13 points under this category..This means that they have less points to earn under the other categories (Smart Location and Linkage, and Neighborhood Pattern and Design), which have a total of 32 criteria worth one point each4. Therefore, the maximum points a new construction project can earn under these categories are 110 - 25 - 13 = 72 points. Adding the regional priority credits, the maximum possible points a new construction project can earn are 72 + 4 = 76 points..To achieve Platinum certification, a new construction project must earn at least 80 points1. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 80 - 76 =.4 points.under each of the four categories: Smart Location and Linkage, Neighborhood Pattern and Design, Green Infrastructure and Buildings, and Regional Priority Credits. Hence, the answer is D..16.

• Question 284:

  In the context of a LEED project, the charrette is a

  A. set of preliminary design specifications submitted by project team members
  B. forum at which the final schematic of the project is presented to the community
  C. procedure through which experts are selected to participate on the project team
  D. meeting of stakeholders, project team members and others to establish project objectives
  D. meeting of stakeholders, project team members and others to establish project objectives

  ---

  In the context of a LEED project, the charrette is a meeting of stakeholders, project team members and others to establish project objectives. The charrette is a collaborative and participatory process that involves brainstorming, discussing, and generating ideas and solutions for the project's sustainability goals, design strategies, performance targets, and evaluation methods. The charrette is usually held at the early stages of the project to ensure alignment and integration among all parties involved. The

  LEED Green Associate Candidate Handbook states that one of the steps in the integrative process is to "conduct a preliminary LEED assessment with key project team members, including owner" [1, p. 12]..

• Question 285:

  The Commissioning (Cx) Process has been structured to coincide with the phases of a generic project in which of the following sequences of phases?

  A. OPR, Design, Construction, Operations and Maintenance
  B. Basis of Design (BOD), OPR, Cx, Construction
  C. Pre-Design, Design, Construction, Occupancy and Operations
  D. Basic Design, Construction, Cx, Owner's Project Requirements (OPR)
  C. Pre-Design, Design, Construction, Occupancy and Operations

  ---

  According to LEED guidelines:

  "Integrated Project Delivery phases: Pre-Design, Design, Bidding, Commissioning, Occupancy"

  Commissioning aligns with these project phases for quality assurance and system verification.

• Question 286:

  An architect found a source for reclaimed wood doors from a recently demolished building 600 mi. (966 km) away from the project site. Towards which of the following sustainable criteria can the doors be used?

  A. Certified Wood
  B. Materials Reuse
  C. Recycled Content
  D. Local Materials
  B. Materials Reuse

  ---

  The reclaimed wood doors can be used to meet the Materials Reuse credit under the Building Product Disclosure and Optimization category in LEED v4. This credit rewards projects for reusing materials that have been recovered from existing buildings or products, and reduces the demand for virgin materials and the associated environmental impacts. The credit does not have any distance requirements for the source of the reused materials, unlike the Recycled Content and Regional Materials credits.

• Question 287:

  Which materials strategy helps reduce demand for virgin resources?

  A. Increasing packaging volume
  B. Using salvaged building products
  C. Selecting single-use construction items
  D. Specifying fossil fuel-based plastics
  B. Using salvaged building products

  ---

  Salvaged and reused materials reduce extraction impacts and are recognized under the Materials and Resources category.

• Question 288:

  Which of the following is a strategy for reducing indoor water use?

  A. Install submeters
  B. use graywater for hand washing
  C. Reuse Salvaged plumbing fixtures
  D. Install a time-sensitive drip irrigation system
  B. use graywater for hand washing

  ---

  Using graywater for hand washing is a strategy for reducing indoor water use, as it can save potable water that would otherwise be used for this purpose. Graywater is the wastewater that is generated from activities such as bathing, laundry, and dishwashing, which can be treated and reused for non-potable applications, such as toilet flushing, irrigation, and hand washing..Using graywater for hand washing can reduce the indoor water use by up to 40%, according to a study by the Pacific Institute1..LEED v4 recognizes and rewards this strategy in the Indoor Water Use Reduction credit2, which aims to reduce the potable water consumption of a building by at least 25% compared to a baseline3. The other options are not directly related to reducing indoor water use, as they involve different types of measures or systems that are not relevant for saving potable water.

• Question 289:

  A company is considering investing in green power for its operations facilities, but is reluctant because of the high capital investment, maintenance costs and slow initial financial returns. Which of the following is a practical strategy to help the company overcome these obstacles?

  A. Relocate the company to a region that is better suited for harnessing renewable energy
  B. Divert the company's research and development funds to investment in large scale hydroelectric power
  C. Host an on-site renewable energy generation system and agree to buy the power without owning the equipment
  D. Hire employees to staff a new operations department in preparation for the maintenance needs of the new renewable energy equipment
  C. Host an on-site renewable energy generation system and agree to buy the power without owning the equipment

  A charrette is an intensive, multi-disciplinary workshop with the aim of developing a design or vision for a project or planning activity. Charrettes are often conducted to design such things as parks and buildings, or to plan communities or transportation systems. A charrette should take place at the beginning of the project, when the design team can engage with all the stakeholders, including the client, users, consultants, contractors, regulators, and community members. A charrette at this stage can help to: Establish clear goals and objectives for the project Identify opportunities and constraints for the site and program Generate creative and innovative ideas and solutions Foster collaboration and consensus among diverse perspectives Reduce conflicts and delays during later phases of the project Enhance communication and trust among the project team The other options are not appropriate phases for a charrette. Post commissioning is too late to influence the design or planning of the project. During the design process, some decisions may have already been made or some stakeholders may have been excluded. During the construction process, changes may be costly or impractical to implement..

• Question 290:

  Waste water from kitchen sinks is considered blackwater unless

  A. it is for use in toilets
  B. local codes state otherwise
  C. it is only used for drip irrigation
  D. a CIR is submitted and approved
  B. local codes state otherwise

  ---

  Blackwater is wastewater that contains fecal matter and pathogens, such as from toilets..Greywater is wastewater that is less contaminated, such as from showers, sinks, and washing machines1. However, the classification of kitchen sink wastewater may vary depending on local codes and regulations..Some states and authorities consider kitchen sink wastewater as blackwater because it may contain food waste and germs123..Others consider it as greywater if it meets certain quality standards and is used for beneficial purposes, such as irrigation or toilet flushing45. A CIR (Credit Interpretation Request) is a process to seek clarification on a specific credit or prerequisite in a LEED rating system, but it does not change the definition of blackwater or greywater.
