Changed LEED-AP-BD+C Exam Questions

The correct answer is D, provide qualifying electrical vehicle supply equipment in 2% of all parking spaces. According to theLEED V5Reference 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 guide1In 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 inLEED V5and have their own credit, Location and Transportation Credit, Reduced Parking Footprint1References:1:LEED V5Reference Guide for Building Design and Construction, Location and Transportation Credit: Green Vehicles, page 467.

The strategy that will contribute toward the Interior Cross-Contamination Prevention strategy in Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies is to provide a ventilation system specifically for the laundry facility that has no recirculating air. This is because the laundry facility is a space where hazardous gases or chemicals may be present or used, such as detergents, bleach, or fabric softeners. According to theLEED V5Reference Guide for Building Design and Construction, the project must " sufficiently exhaust each space where hazardous gases or chemicals may be present or used (e.g., garages, housekeeping and laundry areas, copying and printing rooms), using the exhaust rates determined in EQ Prerequisite Minimum Indoor Air Quality Performance or a minimum of 0.50 cfm per square foot (2.54 l/s per square meter), to create negative pressure with respect to adjacent spaces when the doors to the room are closed.For each of these spaces, provide self-closing doors and deck-to-deck partitions or a hard-lid ceiling. " 1Therefore, option D is the correct answer. The other options will not prevent cross-contamination from the laundry facility to the locker rooms. Relocating the laundry facility to the basement (option A) may reduce the exposure of the occupants to the laundry chemicals, but it will not eliminate the possibility of cross-contamination to other spaces in the basement. Naturally ventilating the laundry space per ASHRAE 62.1-2010 (option B) may not provide sufficient exhaust to create negative pressure and prevent cross-contamination, especially if the outdoor air quality is poor or the natural ventilation is not well designed. Installing particle filters, with a MERV of 13 or higher or F7 (option C) may improve the air quality in the laundry space, but it will not prevent the hazardous gases or chemicals from escaping to the adjacent spaces through the ventilation system or the gaps in the doors or ceiling.References:LEED V5Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52

Short-term bicycle storage must be located within a maximum walking distance of 600 ft. (182.88 m) from a main entrance. The purpose is to ensure that visitors and other short-duration bicycle users receive convenient, visible, and practical access to the building. Storage should also be positioned in a safe location and should allow bicycles to be securely locked without obstructing pedestrian circulation or accessible routes. The distance should be evaluated along the actual walking route rather than by drawing a straight radius through buildings, barriers, or inaccessible areas. Locations 800 ft. away exceed the permitted distance, while 400 ft. would comply but is not the maximum allowed distance. Therefore, Option A states the applicable maximum.

The referenced standard forIndoor Environmental Quality (IEQ) Prerequisite: Minimum Indoor Air Quality (IAQ) Performancein LEED AP ID+C projects isASHRAE 62.1 - 2010. ASHRAE 62.1 specifies ventilation rates and air quality requirements for acceptable indoor air quality in commercial buildings, establishing the minimum standards needed to maintain health and comfort. ASHRAE 62.2 (A) is relevant to low-rise residential buildings, ASHRAE 90.1 (B) covers energy standards, and ASHRAE 55 (C) relates to thermal comfort rather than air quality.
