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

The credit that should be pursued when considering the regional context of frequent power supply grid fluctuations (brown-outs) is Energy and Atmosphere Credit, Demand Response. This credit encourages participation in demand response programs that reduce peak electricity demand and help stabilize the grid. It also provides an opportunity to earn regional priority points, which are bonus points for credits that address regional environmental issues. The other credits are not directly related to the regional context of brown-outs.

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 V5 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.

A narrow floor plate allows daylight to penetrate more deeply into retail areas, reducing reliance on electric lighting during occupied hours. When combined with appropriate glazing, exterior shading, daylight-responsive controls, and glare management, this strategy can lower lighting energy, reduce internal heat gains, and improve visual connection to the outdoors. These outcomes support both lower operating costs and a better occupant experience. Increasing peak thermal loads directly conflicts with the developer’s energy objective. Reducing parking and supporting electric vehicles improves transportation performance but does not necessarily reduce the mall’s building operating costs or enhance the interior environment. Rainwater collection improves water and stormwater performance, but it has a less direct effect on retail-space experience and lighting costs.
