LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED v5 AP BD+C)

Selecting a high-reflectance interior paint that meets the SCAQMD Rule 1113 can help contribute towards two credits: Indoor Environmental Quality Credit, Low-Emitting Materials and Indoor Environmental Quality Credit, Interior Lighting.The first credit requires that interior paints and coatings comply with the VOC content limits specified by the SCAQMD Rule 1113 or equivalent standards to reduce indoor air contaminants that are odorous, irritating, and/or harmful to the comfort and well-being of installers and occupants1The second credit aims to provide high-quality lighting that supports visual acuity and occupant comfort, and that responds to the needs of the space and its users.One of the strategies to achieve this credit is to use light-colored finishes with a minimum reflectance of 0.7 for ceilings, 0.5 for walls, and 0.2 for floors to increase the effectiveness of daylighting and electric lighting systems2References:1:LEED V5Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Low-Emitting Materials, page 692.2:LEED V5Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Interior Lighting, page 715.

 According to the LEED Reference Guide for Building Design and Construction1, the Indoor Environmental Quality Credit, Indoor Air Quality Assessment, Option 1. Flush-Out requires the project to perform a building flush-out by supplying a total air volume of 14,000 cubic feet of outdoor air per square foot of gross floor area while maintaining an internal temperature of at least 60°F and no higher than 80°F and relative humidity no higher than 60%. The gross floor area of the building is 1,000 ft2 and the ceiling height is 10 ft, so the required volume of supply air for the entire building flush-out is:

14,000 ft3/sf x 1,000 sf = 14,000,000 ft3

The Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide allows projects to follow the recommendations of the ASHRAE 50% Advanced Energy Design Guides (AEDGs) for different building types and climate zones. The AEDGs provide design guidance for buildings that use 50% less energy than those built to the requirements of the ANSI/ASHRAE/IES Standard 90.1-2004 commercial code1. However, not all building types and sizes are covered by the AEDGs. According to the LEED Reference Guide for Building Design and Construction2, the following building types and sizes are eligible for this option:

Small to Medium Office buildings up to 100,000 ft2 (9 290 m2)

Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2)

K-12 School buildings up to 200,000 ft2 (18 580 m2)

Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2)

Therefore, among the given options, only the school project is eligible to pursue this option, as it falls within the size limit for the K-12 School AEDG3.

This option requires the project to classify water from toilets as blackwater, not graywater, because it contains human waste and pathogens that pose a health risk1. Graywater is defined as wastewater that contains fewer contaminants than blackwater, such as water from showers, sinks, and washing machines2. Graywater can be reused for non-potable purposes, such as irrigation and toilet flushing, after appropriate treatment3.

This option requires the project team to use the same building operating schedule and occupancy hours for both the baseline building and the proposed building in the whole building simulation model1. This option ensures that the energy savings are calculated based on the same level of building activity and occupancy, which are major factors that affect the energy performance of a building2.
