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

To comply with LEED BD+C Indoor Environmental Quality (IEQ) Credit: Enhanced Indoor Air Quality Strategies, Option 2, a project must implement at least two of the following enhanced air quality strategies:

Use of an outdoor airflow measurement device to monitor and measure at least 90% of the outdoor air intake flow to ensure proper ventilation.

Advanced filtration systems (such as CEN Class F7 or MERV 13 filters) for mechanically ventilated buildings.

Carbon dioxide (CO₂) monitoring in densely occupied spaces, with alerts for elevated CO₂ levels.

Entryway systems (such as walk-off mats) at all regularly used building entrances to reduce dirt and contaminants.

Option D correctly identifies outdoor airflow measurement as one of the acceptable strategies under Option 2.

Building Product Disclosure and Optimization is based on market transparency, which means providing information about the environmental and social impacts of the products and materials used in the building. The LEED v4 Reference Guide for Building Design and Construction states that "the intent of this credit category is to encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts"1. By disclosing the information about the product ingredients, environmental product declarations, sourcing of raw materials, and material ingredients optimization, the project team can make informed decisions and support the development of a more sustainable market.

This option requires the project to calculate the contributing value of the fixture by multiplying the cost of the fixture by the percentage of recycled content by weight1. Since the shades are 10% of the overall weight of the fixture and are 50% post-consumer recycled content, the contributing value of the fixture is:

$1,500 x 10% x 50% = $75
