Question 48

A downtown office building is unable to construct dedicated parking for its occupants. However, the building developer has partnered with a parking garage to offer discounted parking for its occupants. If the discounted parking rate is $450 per month, how much must the rate be for green vehicles for the building to receive one point for Location and Transportation Credit, Green Vehicles?

A.$90
B.$225
C.$360
D.$405

Question 49

A project attempting to meet the preferred parking requirements for Location and Transportation Credit, Green Vehicles may provide what incentive to meet the requirements and highlight the project sustainable vehicle strategy?

A.Three years of free parking for green vehicles
B.Preferred parking decals for 5% of occupants utilizing carpool vehicles
C.A permanent discounted parking rate of at least 20% for all green vehicles
D.An annual maintenance voucher for at least 5% of occupants driving green vehicles

Correct Answer: C

The Location and Transportation Credit, Green Vehicles aims to reduce transportation-related greenhouse gas emissions by promoting the use of low-emitting, fuel-efficient, and alternative-fuel vehicles1. One of the requirements for this credit is to provide preferred parking for green vehicles for 5% of the total vehicle parking capacity of the project1. Preferred parking is defined as parking that is clearly marked and located in the most convenient spaces available to the driver or nearest to the main entrance of the project2. In addition to providing preferred parking, the project may also offer one or more incentives to encourage the use of green vehicles, such as a discounted parking rate, free parking passes, or rebates for parking fees3. The question asks what incentive may be provided to meet the requirements and highlight the project sustainable vehicle strategy. The correct answer is C. A permanent discounted parking rate of at least 20% for all green vehicles, because this incentive meets the minimum threshold of 20% discount suggested by the LEED Reference Guide for Building Design and Construction3, and it also demonstrates the project's commitment to supporting green vehicles in the long term. The other options are either not sufficient or not relevant for this credit. Option A. Three years of free parking for green vehicles is not sufficient because it is not permanent and may not be attractive enough for drivers to switch to green vehicles. Option B. Preferred parking decals for 5% of occupants utilizing carpool vehicles is not relevant because it does not address green vehicles, but rather carpool vehicles, which are covered by a different credit (Location and Transportation Credit, Reduced Parking Footprint)4. Option D. An annual maintenance voucher for at least 5% of occupants driving green vehicles is not sufficient because it is not directly related to parking and may not be a significant incentive for drivers.

Question 50

A new athletic facility contains a laundry room which is adjacent to the locker rooms. Whichstrategy will contribute toward the Interior Cross-Contamination Prevention strategy in Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies?

A.Relocate the laundry facility to the basement
B.Naturally ventilate the laundry space per ASHRAE 62.1-2010
C.Install particle filters, with a MERV of 13 or higher or F7
D.Provide a ventilation system specifically for the laundry facility that has no recirculating air

Correct Answer: D

Explanation
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 the LEED v4 Reference 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 v4 Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52
