Which of the following strategies can be used to achieve a point in Innovation Credit, Innovation, Option 1. Innovation?
Correct Answer: B
Option 1 of the Innovation credit under LEED v4.1 BD+C rating system (Building Design and Construction) allows for achieving significant, measurable environmental performance using a strategy not addressed in the LEED green building rating system1. Implementing an employee engagement and education plan could be a unique strategy that promotes sustainability and environmental stewardship, which is not specifically addressed in the LEED rating system.
Question 112
A new school with a 20 car parking lot has set aside four preferred parking spaces for green vehicles. What else must the project team provide to achieve Location and Transportation Credit, Green Vehicles?
Correct Answer: D
The correct answer is D, provide qualifying electrical vehicle supply equipment in 2% of all parking spaces. According to the LEED v4 Reference Guide for Building Design and Construction, the Location and Transportation Credit, Green Vehicles, requires that projects provide preferred parking for green vehicles for 5% of the total vehicle parking capacity of the site. Green vehicles are defined as vehicles that achieve a minimum green score of 40 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide1 In addition, projects must provide one of the following: Install alternative-fuel fueling stations for 3% of the total vehicle parking capacity of the site. Alternative fuels are defined by the U.S. Energy Policy Act of 1992 and include biodiesel, electricity, ethanol, hydrogen, natural gas, and propane. Install electrical vehicle supply equipment (EVSE) for 2% of the total vehicle parking capacity of the site. EVSE must be Level 2 or higher as defined by SAE International's J1772 standard. Provide a discounted parking rate of at least 20% for green vehicles. The discounted rate must be available to all customers (not limited by time of day or user groups), publicly posted at the entrance of the parking area, and included in all marketing materials for the parking facility1 In this case, the project team has provided preferred parking for green vehicles for 20% of the total vehicle parking capacity of the site (4 out of 20 spaces), which exceeds the minimum requirement of 5%. However, they still need to provide one of the additional options listed above to achieve the credit. The most feasible option for a school project with a small parking lot would be to install EVSE for 2% of all parking spaces, which would be equivalent to one space. Therefore, answer D is correct. The other answers are incorrect because they do not meet the credit requirements. Answer A is incorrect because providing preferred parking alone is not sufficient to achieve the credit; one of the additional options must also be provided. Answer B is incorrect because providing bike racks is not relevant to this credit, which focuses on green vehicles; bike racks are part of another credit, Location and Transportation Credit, Bicycle Facilities. Answer C is incorrect because providing an additional parking space for a low-emitting and fuel-efficient vehicle would not increase the percentage of preferred parking above 20%, which is already more than enough; moreover, low-emitting and fuel-efficient vehicles are defined differently from green vehicles in LEED v4 and have their own credit, Location and Transportation Credit, Reduced Parking Footprint1 Reference: 1: LEED v4 Reference Guide for Building Design and Construction, Location and Transportation Credit: Green Vehicles, page 467.
Question 113
The project team wants to modify the design of an office building copy room to minimize the risk of airborne contamination to the surrounding space. The design includes a separate exhaust, but due to design constraints the partition walls of the room cannot run deck-to-deck. What can the team do to achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies?
Correct Answer: B
The Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies aims to establish better quality indoor air for the building occupants that promotes their comfort and well-being1. This credit requires the project team to implement several strategies to reduce the exposure of occupants and HVAC systems to environmental tobacco smoke, airborne contaminants, and chemicals1. One of the strategies is to design and construct all interior partitions to full height (deck-to-deck) or provide a hard-lid ceiling for spaces where hazardous gases or chemicals may be present or used2. This strategy helps prevent the migration of contaminants from one space to another through the plenum3. A copy room is an example of such a space, as it may contain printers, copiers, toners, and solvents that can emit volatile organic compounds (VOCs) and particulate matter (PM) into the air4. Therefore, the project team can achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies by providing a hard-lid ceiling for the copy room.

Question 114
Which of the following sinks is classified as a private lavatory faucet under Water Efficiency Credit, Indoor Water Use Reduction?
Correct Answer: C
A sink in a hotel room bathroom is classified as a private lavatory faucet under Water Efficiency Credit, Indoor Water Use Reduction. According to the LEED v4 BD+C Reference Guide, a private lavatory faucet is defined as "a faucet that is not generally accessible and is used only by the building's occupants and not by the public or visitors" 1. A sink in an office restroom, a school classroom, or a shared office restroom are examples of public lavatory faucets, which have different baseline flow rates and requirements. Reference: LEED v4 BD+C Reference Guide, Water Efficiency Category, WEc Indoor Water Use Reduction, page 681.
Question 115
Which of the following strategies is allowed under Energy Atmosphere Credit, Renewable Energy Production, and will help a project achieve Energy Atmosphere Credit, Optimize Energy Performance?
Correct Answer: A
Install an on-site photovoltaic array Installing an on-site photovoltaic array is a direct method to produce renewable energy on the project site, which can be used to achieve points under the Energy Atmosphere Credit for Renewable Energy Production. Additionally, it contributes to optimizing energy performance by generating clean electricity on-site and reducing the need for energy from non-renewable sources. References: As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the installation of on-site renewable energy systems like photovoltaic arrays is encouraged to reduce environmental impacts and improve a building's energy performance. This aligns with the goals of both the Renewable Energy Production and Optimize Energy Performance credits under the LEED rating system. For more detailed information, you can refer to the web-based reference guide in the credit library at USGBC's official website.
