Why is it important to categorize spaces in LEED?
- A.
It helps with floor area calculations
- B.
Depending on the space categorization, the credit requirements may not apply
- C.
The types of spaces are used to determine building density
- D.
Smaller spaces have lower baseline requirements
Correct Answer
B. Depending on the space categorization, the credit requirements may not applyExplanation
Categorizing spaces in LEED is important because depending on the categorization, the credit requirements may not apply. This means that certain spaces may be exempt from certain credit requirements, allowing for more flexibility in achieving LEED certification. By categorizing spaces, it becomes easier to determine which credits are applicable to each space and to prioritize sustainability efforts accordingly. This helps streamline the certification process and ensures that the appropriate credits are pursued for each space.Rate this question:

What are the long term effects of climate change? (Choose 3)
- A.
Increased ozone layer
- B.
Increased glaciers
- C.
Higher temperatures
- D.
Longer droughts
- E.
Reduced CO2 emissions
- F.
Higher sea levels
Correct Answer(s)
C. Higher temperatures
D. Longer droughts
F. Higher sea levelsExplanation
The long-term effects of climate change include higher temperatures, longer droughts, and higher sea levels. As the Earth's temperature rises due to increased greenhouse gas emissions, it leads to a range of consequences. Higher temperatures can disrupt ecosystems, cause heatwaves, and impact human health. Longer droughts result in water scarcity, affecting agriculture, ecosystems, and human populations. Rising sea levels are caused by the melting of glaciers and ice sheets, which leads to coastal flooding, erosion, and displacement of communities. Increased ozone layer, reduced CO2 emissions, and increased glaciers are not directly linked to climate change and are not long-term effects of it.Rate this question:

A building owner's project includes a major HVAC renovation, significant envelope modifications, and core plumbing renovation. An interior fit-out is not part of the project. What LEED rating system would be most appropriate for this project?
- A.
LEED O+M: Existing Buildings
- B.
LEED BD+C: Core and Shell
- C.
LEED BD+C: New Construction
- D.
LEED ID+C: Commercial Interiors
Correct Answer
B. LEED BD+C: Core and ShellExplanation
Based on the information provided, the most appropriate LEED rating system for this project would be LEED BD+C: Core and Shell. This is because the project involves major HVAC renovation, significant envelope modifications, and core plumbing renovation, which are all related to the building's core structure and systems. Since an interior fit-out is not part of the project, the LEED ID+C: Commercial Interiors rating system would not be suitable. The LEED BD+C: New Construction rating system is typically used for projects that involve new construction from the ground up, so it may not be the best fit for this project. LEED O+M: Existing Buildings is focused on the ongoing operation and maintenance of existing buildings, so it would not be appropriate for a project involving major renovations and modifications.Rate this question:

Including task lighting and increasing ventilation levels in a new building has what effect on the triple bottom line?
- A.
Decreased ozone depletion
- B.
Decreased maintenance
- C.
Lower first costs
- D.
Increased occupant performance
Correct Answer
D. Increased occupant performanceExplanation
Including task lighting and increasing ventilation levels in a new building can have a positive impact on the triple bottom line by increasing occupant performance. Task lighting provides focused lighting for specific tasks, improving productivity and reducing errors. Increased ventilation levels help to improve indoor air quality, which can lead to better health and well-being for occupants, resulting in increased performance. This can have a positive effect on the overall productivity and satisfaction of the building's occupants, ultimately benefiting the organization's bottom line.Rate this question:

What product for an entryway system allows for good indoor air quality and is a good material choice?
- A.
Low VOC rubber mat
- B.
Wood flooring made in another country
- C.
Carpeted tile shipped from overseas
- D.
Stone tiles extracted and manufactured locally
Correct Answer
A. Low VOC rubber matExplanation
A low VOC rubber mat is a good choice for an entryway system as it allows for good indoor air quality. VOC stands for volatile organic compounds, which are chemicals that can be released from certain materials and negatively impact air quality. Rubber mats with low VOC emissions are made from materials that have minimal off-gassing, reducing the potential for harmful chemicals to be released into the air. This makes them a safer and healthier option for indoor environments.Rate this question:

Proper ventilation systems remove which of the following contaminants? (Choose 3)
- A.
CFCs
- B.
Material off-gassing
- C.
Radon
- D.
Phosphorus
- E.
CO2 concentrations
Correct Answer(s)
B. Material off-gassing
C. Radon
E. CO2 concentrationsExplanation
Proper ventilation systems are designed to remove contaminants from the air. Material off-gassing refers to the release of volatile organic compounds (VOCs) from materials such as furniture, carpets, and cleaning products. Radon is a radioactive gas that can seep into buildings from the ground, and proper ventilation helps to reduce its concentration. CO2 concentrations can increase in enclosed spaces due to human respiration and combustion processes, and ventilation systems help to remove this excess CO2. Therefore, material off-gassing, radon, and CO2 concentrations are all contaminants that can be removed by proper ventilation systems.Rate this question:

Which of the following should a green cleaning policy include?
- A.
The replacement of Minimum Efficiency Reporting Value (MERV) filters and the selection of low VOC materials, furniture, and finishes
- B.
A waste stream audit of recyclable materials and instructions for calibrating indoor air quality sensors
- C.
Standards for selecting products and technologies and certification of cleaning equipment
- D.
Measures to prevent against unwanted pests and the amount of waste to divert from the waste stream
Correct Answer
C. Standards for selecting products and technologies and certification of cleaning equipmentExplanation
A green cleaning policy should include standards for selecting products and technologies and certification of cleaning equipment. This means that the policy should outline specific criteria and guidelines for choosing cleaning products and technologies that are environmentally friendly and sustainable. It should also require certification of the cleaning equipment used to ensure that it meets certain environmental standards. This is important in promoting sustainability and reducing the environmental impact of cleaning practices.Rate this question:

When would a project team member use the HERS Index?
- A.
When measuring the amount of rainfall on a site
- B.
When determining the minimum energy performance of a two-story residential project
- C.
During the Discovery phase of water-related systems
- D.
When calculating the minimum indoor air quality of a warehouse
Correct Answer
B. When determining the minimum energy performance of a two-story residential projectExplanation
The HERS Index is a rating system used to measure the energy efficiency of a home. It provides a standardized way to determine the energy performance of a residential project. By using the HERS Index, project team members can assess the energy efficiency of a two-story residential project and determine if it meets the minimum energy performance requirements. This allows them to make informed decisions about energy-saving measures and ensure that the project meets energy efficiency standards.Rate this question:

What are examples of structural incentives that may be available to a developer to encourage green building? (Choose 2)
- A.
Fee waivers
- B.
Density bonuses
- C.
Tax credits
- D.
Grants
- E.
Expedited review of permits
Correct Answer(s)
B. Density bonuses
E. Expedited review of permitsExplanation
Structural incentives are tangible benefits that developers can receive to promote green building practices. Density bonuses allow developers to construct more units or increase building height in exchange for incorporating sustainable features. This encourages the construction of environmentally friendly buildings. Expedited review of permits reduces the time and effort required for developers to obtain necessary approvals, making it easier and more attractive to pursue green building projects. Both of these incentives provide direct benefits to developers and incentivize them to prioritize sustainability in their projects.Rate this question:
