Question #8
A rectangular office building is located in an extremely humid climate and is shaded by very large adjacent buildings on all four sides.
If the building owner wants to decrease the annual energy cost for operating the building, which of the following would be the best design approach?
- A . Install glazing with a higher solar heat gain factor
- B . Install photovoltaic panels on the sides of the building
- C . Increase outdoor air intake quantities during summer months
- D . Recover waste energy through exhaust air energy recovery systems
Correct Answer: D
D
Explanation:
The best design approach for the office building is D. Recover waste energy through exhaust air energy recovery systems.
This is because:
– Installing glazing with a higher solar heat gain factor would increase the cooling load and energy consumption of the building, especially in an extremely humid climate where heat gain is high1.
– Installing photovoltaic panels on the sides of the building would generate electricity from solar radiation, but it would not reduce the cooling load or energy consumption of the building, unless the electricity is used to power a heat pump or other cooling device2.
– Increasing outdoor air intake quantities during summer months would provide more fresh air to dilute the indoor pollutants and improve the indoor air quality, but it would not reduce the cooling load or energy consumption of the building, unless it is combined with a ventilation system that recovers waste energy from the exhaust air stream34.
An exhaust air energy recovery system (ERV) is a type of mechanical ventilation that uses a heat exchanger to transfer heat between two streams of air: one that enters the building and one that exits. The ERV pre-cools and dehumidifies the incoming ventilation air bysending the rejected heat into the exhaust airstream to cool the condenser coil at a lower temperature. This reduces both the cooling load and energy consumption of the building, as well as improving its indoor humidity levels34. An ERV can also provide some fresh outdoor air to meet ASHRAE Standard 62 ventilation rates5.
Therefore, an ERV is a more efficient and effective design approach than glazing, photovoltaic panels, or increased outdoor air intake quantities for reducing the annual energy cost for operating an office building in an extremely humid climate and shaded by very large adjacent buildings on all four sides.

Question #24
A LEED Building Design and Construction project includes an outdoor stage for theatrical performances. In pursuit of Sustainable Sites Credit, Light Pollution Reduction the engineer has specified an LED fixture to illuminate actors on the stage while limiting light pollution.
Which of the following suggestions should the LEED AP give to the project owner?
- A . Modify the design to enclose the performance areas
- B . Calculate the return on investment over the 20-year life of the project
- C . Compare the energy consumption against an alternative
- D . Inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction
Correct Answer: D
D
Explanation:
The Sustainable Sites Credit, Light Pollution Reduction aims to minimize the adverse effects of artificial lighting on the night sky, human health, and wildlife1. However, the credit does not apply to lighting that is required for safety, security, or emergency purposes2. According to the LEED Reference Guide for Building Design and Construction, lighting for theatrical performances is considered an emergency purpose and is exempt from the credit requirements3. Therefore, the LEED AP should inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction and does not need to be modified or compared to an alternative. Enclosing the performance areas would not reduce light pollution, but rather increase energy consumption and affect the outdoor experience. Calculating the return on investment over the 20-year life of the project is irrelevant to the credit and would not help achieve it.

- D . 15 dwelling units per acre (36 dwelling units per hectare) and a FAR of 0.70
Correct Answer: C
C
Explanation:
The surrounding residential density is calculated by dividing the total number of dwelling units by the total residential land area. In this case, it would be 780 dwelling units divided by 60% of 130 acres, which equals approximately 13 dwelling units per acre (or 32 dwelling units per hectare).
The nonresidential density, or Floor Area Ratio (FAR), is calculated by dividing the total nonresidential building floor area by the total nonresidential land area. In this case, it would be 1,600,000 ft² divided by 40% of 130 acres, which equals a FAR of approximately 0.47.
These calculations are used when attempting to achieve the Location and Transportation Credit, Surrounding Density and Diverse Uses, under the LEED AP BD+C V4 rating system.

Question #34
Which of the following will result in a higher demand for potable water use in irrigation?
- A . Sparsely planted area
- B . Drip irrigation system
- C . High evapotranspiration rate
- D . Rainwater harvesting system
Correct Answer: C
C
Explanation:
The answer is C. A high evapotranspiration rate will result in a higher demand for potable water use in irrigation. Evapotranspiration is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants. The higher the evapotranspiration rate, the more water is lost from the soil and plants, and the more irrigation is needed to replenish the moisture. The other options will not increase the demand for potable water use in irrigation. A sparsely planted area will have less vegetation and less transpiration, reducing the water demand. A drip irrigation system will deliver water directly to the plant roots, minimizing evaporation and runoff, and saving water. A rainwater harvesting system will collect and store rainwater for irrigation, reducing the reliance on potable water sources. For more information on outdoor water use reduction and irrigation efficiency, you can refer to the LEED v4 Reference Guide for Building Design and Construction1or the Water Sense Water Budget Tool2.

Question #40
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 . 12,500 ft2 (1 160 m2)
- B . 15,000 ft2 (1 400 m2)
- C . 25,000 ft2 (2 300 m2)
- D . 35,000 ft2 (3 250 m2)
Correct Answer: C
C
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).

Question #64
For major renovation and new construction projects, the required energy and water-related system analyses should be the same except for
- A . site conditions
- B . massing and orientation
- C . plug and process load needs
- D . building envelope performance
Correct Answer: C
C
Explanation:
For major renovation and new construction projects, the required energy and water-related system analyses should be the same except for plug and process load needs. Plug and process loads are the electrical loads that are not related to lighting, heating, ventilation, and air conditioning (HVAC)systems, such as computers, appliances, equipment, and machinery. Plug and process load needs may vary depending on the type and function of the building, and they can have a significant impact on the energy performance and demand of the building. Therefore, the project team should analyze the plug and process load needs for each project and design strategies to reduce or optimize them. The other factors, such as site conditions, massing and orientation, and building envelope performance, are common to both major renovation and new construction projects, and they should be analyzed in the same way for both types of projects.

- D . the parcels are part of a land trust or conservation organization for which the LEED project provides financial support for in the Sustainable Sites Credit, Site Development Credit, Protect or Restore Habitat, Option 2. Financial Support
Correct Answer: B
B
Explanation:
In determining the LEED project boundaries, the LEED AP may include non-contiguous parcels of land if the parcels directly support or are associated with normal building operations and are accessible to the project’s occupants. This is according to the Minimum Program Requirements (MPRs) for LEED v4.1, which state that non-contiguous parcels of land may be included within the LEED project boundary if they meet these criteria1. Facilities such as parking lots, bicycle storage, shower/changing facilities, and/or on-site renewable energy that are outside of the LEED project boundary may also be included in certain prerequisites and credits if they directly serve the LEED project and are not double-counted for other LEED projects1. The other options are not valid reasons to include non-contiguous parcels of land within the LEED project boundary. Temporary uses such as parking or staging that are owned and managed by a third party do not directly support or are associated with normal building operations of the LEED project1. Existing public preservation easements or resource protection areas that are directly adjacent to the LEED project boundary are not considered as part of the LEED project boundary, unless they are owned by the project owner or the project team has permission to use them2. Land trusts or conservation organizations for which the LEED project provides financial support are not considered as part of the LEED project boundary, unless they are located within the same EPA Level III ecoregion as the project site3.

Question #70
A commercial new construction project consists of mixed space usage. When deciding which LEED rating system to use, the LEED AP should follow which of the following rules?
- A . If a rating system is appropriate for less than 50% of the gross area of the LEED project space then the rating system must not be used
- B . If a rating system is appropriate for more than 50% of the gross floor area of LEED project space, then that rating system must be used
- C . If a rating system is appropriate for 30% to 60% of the gross floor area, the project team must independently assess their situation and decide which rating system is most applicable
- D . If a rating system is appropriate for 40% to 60% of the gross floor area, the project team must independently assess their situation and decide which rating system is most applicable
Correct Answer: D
D
Explanation:
According to the LEED v4: Building Design + Construction Guide, the 40/60 rule provides guidance for making a decision when several rating systems appear to be appropriate for a project. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type. If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used. If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used. If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams must independently assess their situation and decide which rating system is most applicable1.

Question #79
Which of the following strategies will aid in reducing indoor water use?
- A . Design drip irrigation for landscape
- B . Use high-efficiency HVAC systems
- C . Exclude janitor closets in the building
- D . Optimize consumption of showerheads
Correct Answer: D
D
Explanation:
According to the LEED v4: Building Design + Construction Guide, one of the strategies to reduce indoor water use is to optimize the consumption of showerheads by selecting fixtures that have a flow rate lower than the baseline of 2.0 gallons per minute (gpm) at 80 psi, or a local equivalent for projects outside the U.S. This can help the project achieve the Water Efficiency Prerequisite, Indoor Water Use Reduction, and the Water Efficiency Credit, Indoor Water Use Reduction, by reducing the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline1.
The other choices are not strategies to reduce indoor water use, because:
– Designing drip irrigation for landscape is a strategy to reduce outdoor water use, not indoor water use1.
– Using high-efficiency HVAC systems is a strategy to reduce energy use, not water use, although it may have some indirect water savings by reducing the cooling tower water use2.
– Excluding janitor closets in the building is not a feasible or practical strategy, as janitor closets are necessary for cleaning and maintenance purposes, and may also be required by codes or standards3.

According to the LEED v4: Building Design + Construction Guide, one of the strategies to reduce indoor water use is to optimize the consumption of showerheads by selecting fixtures that have a flow rate lower than the baseline of 2.0 gallons per minute (gpm) at 80 psi, or a local equivalent for projects outside the U.S. This can help the project achieve the Water Efficiency Prerequisite, Indoor Water Use Reduction, and the Water Efficiency Credit, Indoor Water Use Reduction, by reducing the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline1.
The other choices are not strategies to reduce indoor water use, because:
– Designing drip irrigation for landscape is a strategy to reduce outdoor water use, not indoor water use1.
– Using high-efficiency HVAC systems is a strategy to reduce energy use, not water use, although it may have some indirect water savings by reducing the cooling tower water use2.
– Excluding janitor closets in the building is not a feasible or practical strategy, as janitor closets are necessary for cleaning and maintenance purposes, and may also be required by codes or standards3.

- A . Carbon offsets
- B . Daylighting strategies
- C . Passive solar strategies
- D . Produced electricity consumed on-site
Correct Answer: D
D
Explanation:
The Energy and Atmosphere Credit, Renewable Energy Production rewards projects that use renewable energy systems to offset building energy costs1. According to the LEED Reference Guide for Building Design and Construction2, the credit has two options: Option 1. On-Site Renewable Energy and Option 2. Off-Site Renewable Energy. Option 1 requires the project to use renewable energy systems that are located on the project site and that produce electricity or thermal energy for the project. The amount of renewable energy production is calculated based on the percentage of the annual energy cost that is offset by the renewable energy systems. Option 2 requires the project to use renewable energy systems that are located off the project site and that are owned by the project or have a long-term contract with the project. The amount of renewable energy production is calculated based on the percentage of the annual energy use that is offset by the renewable energy systems.
Therefore, among the given options, only Option D is relevant to the credit requirements, as it implies that the solar photovoltaic system is located on the project site and that the produced electricity is consumed by the project. The other options, such as carbon offsets, daylighting strategies, and passive solar strategies, are not directly related to the credit requirements, although they may have other benefits for the project.

- A . HVAC air system for air conditioning
- B . Electrical lighting system during peak use hours
- C . Water flow system used for public faucets and toilets
- D . Condenser water system with a cooling tower and condenser water pumps
Correct Answer: D
D
Explanation:
A condenser water system with a cooling tower and condenser water pumps is classified as a system composed of discrete pieces of equipment that can be metered together for the purposes of Energy and Atmosphere Credit, Advanced Energy Metering. This is because the condenser water system is a single energy end use that serves a specific function and can be isolated from other systems1. HVAC air system, electrical lighting system, and water flow system are not considered as single energy end uses, but rather as multiple energy end uses that serve different functions and cannot be easily isolated2.

Question #88
Which of the following is the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
- A . At least 6 ft. (2 m) above the floor
- B . At least 3 ft. (1 m) away from windows
- C . Between 3 ft. and 6 ft. (1 m and 2 m) above the floor
- D . On the ceiling 3 ft. (1 m) away from adjacent walls
Correct Answer: C
C
Explanation:
According to the LEED v4: Building Design + Construction Guide, the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance is between 3 ft. and 6 ft. (1 m and 2 m) above the floor. This is one of the requirements for Option 2. Naturally Ventilated Spaces, which applies to projects that rely on natural ventilation for all or part of the occupied spaces. The CO2 sensors must be located in each zone with natural ventilation openings, and must be capable of generating an alarm when the CO2 concentration exceeds the design value1.
The other choices are not correct, because:
At least 6 ft.(2 m) above the floor is the location of CO2 sensors in mechanically ventilated spaces, not naturally ventilated spaces1.
At least 3 ft.(1 m) away from windows is a general guideline for locating CO2 sensors, but it does not specify the height above the floor2.
On the ceiling 3 ft.(1 m) away from adjacent walls is not a recommended location for CO2 sensors, as it may not reflect the actual CO2 concentration at the breathing zone of the occupants2.

Question #89
The Solar Reflectance Index (SRI) includes the measure of a material’s
- A . color (shade of gray)
- B . ability to reflect solar radiation
- C . ability to absorb solar radiation
- D . ability to reflect thermal radiation
Correct Answer: B
B
Explanation:
The Solar Reflectance Index (SRI) is a measure of the roof’s ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI is calculated using the roof surface’s Solar Reflectance (SR) and Thermal Emittance (TE). SR is the fraction of solar energy that is reflected by the roof, and TE is the relative ability of the roof surface to radiate heat. Therefore, SRI includes the measure of a material’s ability to reflect solar radiation, but not its ability to absorb or emit thermal radiation.
