What LEED Building Design and Construction rating system mandates a preliminary LEED meeting with the principal members of the project team to create a LEED action plan that includes the anticipated certification tier, targeted credits and parties responsible for each credit?
Correct Answer: C
Data centers is the only LEED BD+C rating system that mandates a preliminary LEED meeting with the principal members of the project team to create a LEED action plan that includes the anticipated certification tier, targeted credits and parties responsible for each credit. This is because data centers have unique design and operational characteristics that require a more integrative and customized approach to achieve LEED certification.The preliminary LEED meeting is intended to facilitate early goal setting, alignment, and communication among the project team members12.Reference: LEED BD+C Reference Guide, Data Centers, page 91;LEED V5.1 BD+C: Data Centers
Question 137
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?
Correct Answer: D
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.

Question 138
The Sustainable Sites Credit, Heat Island Reduction takes into account both new and three-year aged Solar Reflectance Index (SRI) values for roofing material because
Correct Answer: B
SRI generally decreases with age The Solar Reflectance Index (SRI) is a measure of the ability of a surface to reflect solar heat, as shown by a small temperature rise. It is calculated using the values of solar reflectance and thermal emittance of the surface. The higher the SRI, the lower the heat island effect. However, SRI generally decreases with age due to factors such as weathering, dirt accumulation, and biological growth. Therefore, the Sustainable Sites Credit, Heat Island Reduction takes into account both new and three-year aged SRI values for roofing material to ensure that the material maintains a high level of reflectance over time.

Question 139
The use of lead, mercury, copper and cadmium should be limited because they all
Correct Answer: A
According to the LEED v4: Building Design + Construction Guide, lead, mercury, copper and cadmium are examples of persistent bioaccumulative toxins (PBTs) that should be limited in building products. PBTs are substances that remain in the environment for long periods of time, accumulate in living organisms, and pose health risks to humans and wildlife. One of the prerequisites for the Materials and Resources Credit, Building Product Disclosure and Optimization - Material Ingredients, is to reduce the use of products that contain PBTs above certain thresholds1.

Question 140
Which strategy should be employed to improve daylighting when designing a new building?
Correct Answer: B
Increase the number of skylights Skylights are openings in the roof or ceiling that allow natural light to enter the building. They can improve daylighting by providing more uniform and diffuse illumination, reducing the need for artificial lighting, and enhancing the visual comfort and well-being of occupants. Skylights can also reduce cooling loads by minimizing solar heat gain through the roof. However, skylights must be designed carefully to avoid glare, overheating, and heat loss issues.
