QUESTION: 133

Which rating system is being used if all of the credits below have been submitted towards certification?
- Location and Transportation Credit, Reduced Parking Footprint
- Energy and Atmosphere Credit, Fundamental Refrigerant Management
- Indoor Environmental Quality Credit, Acoustic Performance
- Materials and Resources Credit, Persistent, Bio accumulative, and Toxic (PBT) Source Reduction - Lead, Cadmium, and Copper

Building Design and Construction: Schools
Building Design and Construction: Healthcare
Building Design and Construction: Hospitality
Building Design and Construction: Data Centers

Answer(s): C

Explanation:

The rating system that is being used if all of the credits below have been submitted towards certification is Building Design and Construction: Hospitality. This is because the Location and Transportation Credit, Reduced Parking Footprint and the Indoor Environmental Quality Credit, Acoustic Performance are only available for the Hospitality rating system among the four options.

The other two credits are common for all the rating systems.

QUESTION: 134

A project's total site area is 240,000 ft2 (22 297 m2) and the building footprint is 40,000 ft2 (3 716 m2). How much outdoor space and vegetated space must it provide to earn Sustainable Sites Credit, Open Space?

60,000 ft2 (5 574 m2) of outdoor space of which 15,000 ft2 (1 394 m2) must be vegetated
60,000 ft2 (5 574 m2) of outdoor space of which 50,000 ft2 (4 645 m2) must be vegetated
72,000 ft2 (6 689 m2) of outdoor space of which 18,000 ft2 (1 672 m2) must be vegetated
72,000 ft2 (6 689 m2) of outdoor space of which 60,000 ft2 (5 574 m2) must be vegetated

Answer(s): C

Explanation:

According to the LEED v4 Reference Guide for Building Design and Construction, the project must provide outdoor space that is at least 30% of the total site area (including the building footprint), of which at least 25% must be vegetated. In this case, the project must provide 0.3 x 240,000 ft2 = 72,000 ft2 (6 689 m2) of outdoor space, of which 0.25 x 72,000 ft2 = 18,000 ft2 (1 672 m2) must be vegetated. Therefore, option C is the correct answer.

QUESTION: 135

Which of the following will result in a higher demand for potable water use in irrigation?

Sparsely planted area
Drip irrigation system
High evapotranspiration rate
Rainwater harvesting system

Answer(s): C

Explanation:

The answer is C. A high evapotranspiration rate will result in a higher demand for potable water use in irrigation. Evapotranspiration is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants. The higher the evapotranspiration rate, the more water is lost from the soil and plants, and the more irrigation is needed to replenish the moisture. The other options will not increase the demand for potable water use in irrigation. A sparsely planted area will have less vegetation and less transpiration, reducing the water demand. A drip irrigation system will deliver water directly to the plant roots, minimizing evaporation and runoff, and saving water. A rainwater harvesting system will collect and store rainwater for irrigation, reducing the reliance on potable water sources. For more information on outdoor water use reduction and irrigation efficiency, you can refer to the LEED v4 Reference Guide for Building Design and Construction or the WaterSense Water Budget Tool.

QUESTION: 136

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

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

Answer(s): 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."1 Therefore, 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.
