LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

The make and model of fixtures is required in determining the baseline for the Water Efficiency Prerequisite, Indoor Water Use Reduction. This information is used to calculate the baseline water consumption of the building, which is then compared to the proposed water use to determine the percentage reduction.

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 References: 1: LEED v4 Reference Guide for Building Design and Construction, Location and Transportation Credit: Green Vehicles, page 467.

Using plug-in devices can affect the energy performance of the building, which is one of the criteria for achieving Indoor Environmental Quality Credit. Thermal Comfort. The LEED v4 Reference Guide for Building Design and Construction states that "the project team must demonstrate that the proposed design meets the minimum energy performance requirements of ASHRAE Standard 90.1-2010, Appendix G, with errata"1. Plug-in devices are considered as part of the process loads in the energy model, and they can increase the energy consumption and demand of the building. Therefore, the project team must account for the plug-in devices in the energy model and ensure that the proposed design meets or exceeds the baseline performance rating.
