A project team is deciding on the impact of a proposed concrete walkway. Which of the following will be impacted as a result of adding the walkway?
Correct Answer: A
Explanation:
Adding a concrete walkway will increase the site’s impervious cover, which is the percentage of the site area that does not allow water to infiltrate into the ground1. Impervious cover can affect the site’s stormwater management, heat island effect, and habitat quality. The project team should consider using permeable paving materials, vegetated roofs, or rain gardens to reduce the impervious cover and mitigate its impacts2. The other options are not directly impacted by adding a concrete walkway. Project density calculations are based on the floor area ratio and the number of occupants, not the site features3. Erosion and sediment control plan during construction is required for any site disturbance, regardless of the type of material used4. Air quality as a result of off gassing that occurs as concrete cures is not a significant issue for outdoor applications, and can be minimized by using low-emitting concrete products5.
Question 2
What is the basis of energy consumption in determining the percentage of green power or carbon offsets?
Correct Answer: B
Explanation:
B. Quantity is the correct answer because the percentage of green power or carbon offsets is determined based on the amount (quantity) of energy consumed. Organizations calculate how much energy they use and then purchase an equivalent percentage of green power or carbon offsets to match that consumption. The calculation is based on measurable energy quantities (such as kilowatt-hours), not on the quality, efficiency, or performance of the energy source.
Question 3
When the LEED AP is applyingthe Integrative Process to a Building Design and Construction project, which of the following information is required to be present in the Owner's Project Requirements (OPR)?
Correct Answer: D
Explanation:
According to, page 11, scenario based risk identification involves “creating different scenarios based on varying assumptions about how events might unfold”. This can help explore alternative ways to achieve an objective under different circumstances. Energy efficiency goals and training requirements are required to be present in the Owner’s Project Requirements (OPR) when applying the Integrative Process to a Building Design and Construction project. According to the LEED v4 BD+C Reference Guide, the OPR is a document that details the ideas, concepts, and criteria that are determined by the owner to be important to the success of the project 1. The OPR must include, among other things, the following information related to energy efficiency 1: • • • • • The owner’s energy performance goals and expectations The owner’s requirements for energy metering and monitoring The owner’s requirements for energy modeling and analysis The owner’s requirements for commissioning and verification The owner’s requirements for training and documentation The other options are not required to be present in the OPR, as they are either related to other aspects of the project, such as codes and standards, interior finishes, or project team members, or they are not relevant to the Integrative Process, which focuses on early analysis of energy, water, and site systems 2.
