Which of the following is required to earn Energy and Atmosphere Credit, Renewable Energy Production if using a Solar Photovoltaic System?
Correct Answer: D
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.
LEED-AP-BD-C Exam Question 62
When working on a renovation project, asbestos containing materials have been found on the perimeter walls. When calculating the percentage of building being reused under the Materials and Resources Credit, Building Life-Cycle Impact Reduction, the materials remediated will be
Correct Answer: B
The Materials and Resources Credit, Building Life-Cycle Impact Reduction, rewards projects that reuse existing building structures and envelopes, or salvage materials from off-site or on-site sources. According to the LEED v4 Reference Guide for Building Design and Construction, the project team must calculate the percentage of building being reused by dividing the area of the existing building structure and envelope that is reused by the total area of the completed building structure and envelope1. However, the project team must exclude from the calculation any hazardous materials that are remediated as a part of the project, such as asbestos, lead, mold, or PCBs1. Therefore, the asbestos containing materials found on the perimeter walls will be excluded from the calculation, regardless of the volume.
LEED-AP-BD-C Exam Question 63
Increasing which of the following variables will require an increase in the outdoor airflow rate under Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
Correct Answer: B
The outdoor airflow rate is the amount of outdoor air that is supplied to the building by the ventilation system to dilute indoor air pollutants and provide fresh air for the occupants. The outdoor airflow rate depends on the ventilation standard that the project follows, which can be either ASHRAE 62.1-2010 or CEN Standard EN 15251-20071. Both standards specify the minimum outdoor airflow rate per person and per unit area for different occupancy types and zones. Therefore, increasing the number of occupants will require an increase in the outdoor airflow rate to maintain the minimum ventilation level. The other variables, such as supply air velocity, system ventilation efficiency, and supply air temperature set point, do not directly affect the outdoor airflow rate, although they may influence the energy consumption and thermal comfort of the ventilation system.
LEED-AP-BD-C Exam Question 64
Which of the following would be classified as a public use faucet?
Correct Answer: D
Under LEED BD+C Water Efficiency (WE) credits, a public use faucet is defined as a sink or faucet that is available for general use in shared spaces, rather than being restricted to private, residential, or patient- specific settings. * School classroom sinks are used by multiple people throughout the day, making them a public use fixture. * Patient room sinks, hotel sinks, and dorm room sinks are considered private use fixtures, as they are designated for individual users or a limited number of occupants. LEED water efficiency calculations differentiate between private and public use fixtures due to differences in water usage patterns and flow rate requirements.

LEED-AP-BD-C Exam Question 65
What reference standard is used to determine compliance with the Energy and Atmosphere Prerequisite, Minimum Energy Performance when the whole building energy modeling option is used?
Correct Answer: C
ASHRAE 90.1-2010 is the reference standard used to determine compliance with the Energy and Atmosphere Prerequisite, Minimum Energy Performance when the whole building energy modeling option is used. This prerequisite requires demonstrating a 5% improvement in the proposed building performance rating compared to the baseline building performance rating per ASHRAE 90.1-2010, Appendix G1. The baseline building performance rating is based on a building design that meets the minimum requirements of ASHRAE 90.1- 20102.
