According to the Indoor Environmental Quality credit category, which of the following is considered an unoccupied space?
- A. Mechanical and electrical rooms
- B. Restroom
- C. School classroom
- D. Corridor
正解：A
解説：
Explanation
According to the Indoor Environmental Quality credit category of LEED, mechanical and electrical rooms are considered unoccupied spaces. These spaces are typically not intended for human occupancy, except for maintenance or operational purposes, and therefore do not require the same level of environmental control (such as ventilation or temperature control) as occupied spaces.

質問 # 13
Which of the following is a strategy that a design team should consider In order to decrease the Impact of a new construction project?
- A. Increase the project's footprint to maximize roof space for a solar array
- B. Maximize views of the existing wetland
- C. Locate the project in an existing office park with ample parking
- D. Select native plants to provide habitat for local fauna
正解：D
解説：
Selecting native plants to provide habitat for local fauna is a strategy that a design team should consider in order to decrease the impact of a new construction project. Native plants are plants that have evolved in a specific region and have adapted to the local climate and soil conditions. Native plants can offer many benefits for the environment, such as:
Reducing water use and runoff by requiring less irrigation and fertilization Enhancing biodiversity and ecosystem services by supporting native wildlife and pollinators Improving air quality and mitigating climate change by sequestering carbon and reducing greenhouse gas emissions Increasing soil health and stability by preventing erosion and improving infiltration Creating a sense of place and cultural identity by reflecting the natural heritage of the region The other options are not strategies that would decrease the impact of a new construction project. Maximizing views of the existing wetland may improve occupant satisfaction, but it does not necessarily reduce the environmental footprint of the project. Locating the project in an existing office park with ample parking may reduce land use and transportation impacts, but it may also increase heat island effect and stormwater runoff. Increasing the project's footprint to maximize roof space for a solar array may increase renewable energy generation, but it may also increase site disturbance, material use, and energy demand.

質問 # 14
Which of the following techniques IS recommended for preventing the negative effects of indoor pollutants?
- A. Keeping material containers open during construction
- B. Deep cleaning all surfaces during occupant move-in
- C. Specifying and installing low-emitting materials at the source
- D. Keeping doors and windows open after installation of interior finishes
正解：C
解説：
Low-emitting materials are those that have minimal or no emissions of volatile organic compounds (VOCs) and other harmful pollutants that can affect indoor air quality (IAQ)1. Specifying and installing low-emitting materials at the source can help prevent the negative effects of indoor pollutants by reducing the exposure of occupants and workers to these substances2. Some examples of low-emitting materials are paints, coatings, adhesives, sealants, flooring, furniture, and insulation that meet the criteria of third-party certification programs such as Green Seal, Greenguard, or SCS3.
質問 # 15
In a large site that has a short, intense rainy season and a long, dry season, what component of a collected rainwater irrigation system is most likely to make it cost prohibitive over a conventional system?
- A. Landscaping plant selection
- B. Rainwater storage cisterns
- C. Irrigation piping systems
- D. Irrigation control systems
正解：B
解説：
Explanation
Rainwater storage cisterns are components of a collected rainwater irrigation system that are most likely to make it cost prohibitive over a conventional system in a large site that has a short, intense rainy season and a long, dry season. A collected rainwater irrigation system is a system that collects, stores, and distributes rainwater for irrigation purposes. Rainwater storage cisterns are containers that store the collected rainwater until it is needed for irrigation. In a large site that has a short, intense rainy season and a long, dry season, the rainwater storage cisterns would need to be very large and durable to capture and store enough rainwater for the dry season. This would increase the initial cost and maintenance cost of the system compared to a conventional system that uses potable water or groundwater for irrigation1 .

質問 # 16
Which of the following does LEED promote by encouraging compact development?
- A. Urban sprawl
- B. Historic preservation
- C. Walkability
- D. Development of new infrastructure
正解：C
解説：
Explanation
One of the things that LEED promotes by encouraging compact development is walkability. Compact development is a form of urban planning that aims to reduce sprawl and make more efficient use of land and resources by increasing density, diversity, and connectivity of land uses5. Compact development can enhance walkability by creating mixed-use neighborhoods that provide a variety of destinations within walking distance, such as shops, services, workplaces, schools, parks, and transit stops. Walkability can offer multiple benefits for the environment, health, economy, and social equity. For example, walkability can reduce greenhouse gas emissions and air pollution by replacing car trips with walking or transit; improve physical and mental health by increasing physical activity and reducing stress; support local businesses and generate tax revenues by increasing foot traffic and property values; and foster social cohesion and civic engagement by creating vibrant public spaces and enhancing accessibility for all6.

質問 # 17
A project plans to build a campus of buildings. Which of the following strategies should the project team consider to reduce energy demand?
- A. Design buildings to shade each other
- B. Select HVAC equipment without refrigerants
- C. Enroll in a demand response program
- D. Purchase carbon offsets
正解：A
解説：
Designing buildings to shade each other can help reduce energy demand by decreasing cooling loads. By strategically positioning buildings on a site, it's possible to use the buildings themselves to block solar heat gain, reducing the need for air conditioning.

質問 # 18
Sustainable forestry is the practice of maintaining forest resources to meet the long-term forest product needs of humans while maintaining the
- A. quality Of salvaged wood products
- B. biodiversity of the forest and landscape
- C. cost of the forest products
- D. harvesting of the rapidly grown forest
正解：B
解説：
Explanation
Sustainable forestry is the practice of managing forest resources in a way that meets the current and future needs of humans for forest products, while also conserving and enhancing the ecological, social, and economic values of the forest and its surrounding landscape1. One of the key aspects of sustainable forestry is to maintain the biodiversity of the forest, which refers to the variety and abundance of living organisms, such as plants, animals, fungi, and microorganisms, and their interactions within the forest ecosystem2. Biodiversity is important for the health and resilience of the forest, as it provides essential ecosystem services, such as carbon sequestration, water purification, soil formation, nutrient cycling, pollination, pest control, and climate regulation23. Biodiversity also supports the livelihoods, cultures, and well-being of forest-dependent communities and indigenous peoples23.

During which stage of a project is implementation of the Integrative Process most effective in improving performance?
- A. Construction
- B. Construction document
- C. Operation
- D. Early de sign
正解：D
解説：
The Integrative Process is most effective during the early design stage of a project. This is when key decisions about the project are being made that can have a significant impact on its sustainability performance. By considering sustainability objectives from the outset, teams can identify opportunities for synergies and cost savings that may not be apparent later in the project.

質問 # 20
Which strategy for roof coverage best addresses both heat island effect and rainwater runoff from the roof only?
- A. 100% high-albedo
- B. 50% standing seam copper and 50% vegetated
- C. 100% vegetated
- D. 20% high-albedo and 80% conventional
正解：C
解説：
Explanation
A 100% vegetated roof coverage best addresses both heat island effect and rainwater runoff from the roof only. A vegetated roof, also known as a green roof, is a layer of living plants that covers the roof surface. A vegetated roof reduces the heat island effect by providing shade, evapotranspiration, and insulation, lowering the roof temperature and the surrounding air temperature. A vegetated roof also reduces rainwater runoff by retaining and absorbing precipitation, decreasing the volume and peak flow of stormwater leaving the roof.
The other options are not as effective as a 100% vegetated roof coverage in addressing both heat island effect and rainwater runoff from the roof only. A 100% high-albedo roof reflects more solar radiation than a conventional roof, reducing the heat island effect, but it does not reduce rainwater runoff. A 20% high-albedo and 80% conventional roof has a lower reflectance than a 100% high-albedo roof, resulting in a higher heat island effect, and it does not reduce rainwater runoff either. A 50% standing seam copper and 50% vegetated roof has a lower vegetated area than a 100% vegetated roof, resulting in less shade, evapotranspiration, insulation, retention, and absorption, leading to a higher heat island effect and more rainwater runoff.

質問 # 21
By specifying the installation of occupancy sensors for the building's lighting system, what pair of LEED credit categories would be affected?
- A. Indoor Environmental Quality and Energy and Atmosphere
- B. Location and Transportation and Materials and Resources
- C. Innovation and Water Efficiency
- D. Integrative Process and Sustainable Sites
正解：A
解説：
Explanation
Occupancy sensors are devices that detect the presence or absence of people in a space and automatically turn the lights on or off accordingly. By installing occupancy sensors for thebuilding's lighting system, projects can achieve two benefits: improving the indoor environmental quality (IEQ) and reducing the energy consumption.
Occupancy sensors can enhance the IEQ by providing lighting control for individual spaces, allowing occupants to adjust the light levels to their preferences and needs. Occupancy sensors can also save energy by avoiding unnecessary lighting when spaces are unoccupied, thus lowering the electricity demand and greenhouse gas emissions.

質問 # 22
Strategically locating functional and decorative hardscape on a project site may reduce the amount of on-site
- A. waste area
- B. pervious area
- C. sensitive area
- D. impervious area
正解：D
解説：
Explanation
Strategically locating functional and decorative hardscape on a project site can reduce the amount of on-site impervious area. Impervious surfaces are surfaces that do not allow water to infiltrate into the ground (e.g., concrete or asphalt). By reducing these surfaces, we can increase water infiltration, which helps recharge groundwater supplies and reduces stormwater runoff that can lead to erosion and water pollution. References:
LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
質問 # 23
Which label or certification indicates reduced water consumption for appliances?
- A. ASHRAE 90.1
- B. ENERGY STAR
- C. GREENGUARD
- D. ISO 14001:2015
正解：B
解説：
ENERGY STAR is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy that promotes energy efficiency. Products that earn the ENERGY STAR label meet strict criteria for energy efficiency and often for water efficiency as well, helping consumers save money on utility bills and protect the environment through energy-efficient products and practices.

質問 # 24
In addition to the temperature and humidity, what is another factor to consider when implementing thermal comfort strategies?
- A. Acoustics
- B. Air movement
- C. Daylight
- D. Green cleaning
正解：B
解説：
Air movement is a factor that affects the thermal comfort of occupants, as it influences the heat exchange between the human body and the surrounding air1. Air movement can be controlled by mechanical systems, such as fans, or natural systems, such as operable windows2. LEED v4 requires that at least 50% of individual occupant spaces have thermal comfort controls that allow occupants to adjust air movement in their local environment3.
質問 # 25
In order to earn LEED certification, a project must
- A. earn a minimum 0t 50 points or meet a prerequisite
- B. employ a LEED AP on its project team
- C. conduct a whole-building life-cycle assessment
- D. satisfy all prerequisites and earn a minimum number of points
正解：D
解説：
LEED certification is a process that evaluates the environmental performance and sustainability of a building project based on a set of rating systems. To earn LEED certification, a project must satisfy all the mandatory requirements, or prerequisites, of the chosen rating system, and earn a minimum number of points by meeting optional criteria, or credits. The number of points determines the level of certification: Certified (40-49 points), Silver (50-59 points), Gold (60-79 points), or Platinum (80+ points)123.
Employing a LEED AP (Accredited Professional) on the project team is not a requirement for LEED certification, but it can provide an advantage, as LEED APs have demonstrated their knowledge and expertise in green building and LEED rating systems. Having a LEED AP on the project team can also earn one point under the Integrative Process credit4.
Conducting a whole-building life-cycle assessment is not a requirement for LEED certification, but it can be an option for earning points under the Building Life-Cycle Impact Reduction credit. A life-cycle assessment is a method of evaluating the environmental impacts of a building over its entire life span, from extraction of materials to disposal or reuse3.
Earning a minimum of 50 points or meeting a prerequisite is not a sufficient condition for LEED certification, as it does not account for the other prerequisites or the level of certification. A project must meet all the prerequisites and earn at least 40 points to qualify for the lowest level of certification
