The LEED AP Building Design + Construction (LEED AP BD+C) (LEED-AP-BD+C)

LEED v5 places biophilic design within EQc2 Occupant Experience because visual and experiential connections with nature contribute to health, well-being, satisfaction, and emotional connection to the building. Under the Biophilic Environment pathway, LEED specifically recognizes sustained engagement with nature and provides points for Quality Views to natural or urban environments. Such views support psychological restoration, attention, and cognitive well-being rather than directly performing ventilation or temperature-control functions. Option A is incorrect because looking through a fixed window does not exchange indoor and outdoor air or remove pollutants. Option C confuses visual awareness of weather with actual thermal-environment control. The primary value of access to nature and quality views in this context is the positive human response associated with visual connections to natural elements. Therefore, Option B best represents the intended quality-of-life benefit.

The make and model of fixtures is required in determining the baseline for the Water Efficiency Prerequisite, Indoor Water Use Reduction.This information is used to calculate the baseline water consumption of the building, which is then compared to the proposed water use to determine the percentage reduction.

QUSTION NO: 147

In order to comply with Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2. Additional Enhanced IAQ Strategies

A. all entrances to the building must have entryway systems 10 ft. (3 m) long in the direction of travel

B. CO2 monitors must be fitted in all densely occupied spaces and configured to provide an alert

C. all outdoor air supply systems must have an airflow measurement device that measures at least 90% of the airflow

D. all particle filters in the ventilation system must meet Comité Européen de Normalisation (CEN) standard Class F7 or better

Answer: D

To comply with the Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2, all particle filters in the ventilation system must meet the Comité Européen de Normalisation (CEN) standard Class F7 or better.This requirement ensures that the air quality inside the building is maintained at a high standard, contributing tothe health and well-being of the occupants.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources1

According to theLEED V5Reference Guide for Building Design and Construction, the Carbon Dioxide Monitoring strategy requires CO2 monitors to be located in each densely occupied space, which is defined as a space with a design occupant density of 25 people or more per 1,000 square feet (93 square meters).This strategy is intended to provide feedback on ventilation system performance and indoor air quality12References:1:LEED V5Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Enhanced Indoor Air Quality Strategies, Option 2: Additional Enhanced IAQ Strategies, Strategy 3: Carbon Dioxide Monitoring, page 704.2:LEED V5Reference Guide for Building Design and Construction, Glossary, page 1019.

Detailed Explanation:

For the Brownfield Remediation option under the High-Priority Site credit, the project site must include contaminated soil or groundwater requiring cleanup to improve environmental conditions. This credit incentivizes the redevelopment of previously unusable or hazardous sites, helping to promote environmental restoration and sustainable land use.

ASHRAE 90.1-2010 is the reference standard used to determine compliance with the Energy and Atmosphere Prerequisite, Minimum Energy Performance when the whole building energy modeling option is used.This prerequisite requires demonstrating a 5%improvement in the proposed building performance rating compared to the baseline building performance rating per ASHRAE 90.1-2010, Appendix G1.The baseline building performance rating is based on a building design that meets the minimum requirements of ASHRAE 90.1-20102.References:

Whileincreased ventilation improves indoor air quality, it can also lead tohigher energy consumption, impactingLEED BD+C Energy and Atmosphere (EA) Credit: Optimize Energy Performance.

More ventilation requires more heating/cooling energy, which canincrease energy useandreduce overall energy efficiency.

This can lower the points earned for energy optimization, sinceLEED rewards projects that minimize energy consumption.

Other credits (Options A, B, and D)are not directly affected by increased ventilation rates.

Energy performance is negatively impacted when additional ventilation leads to increased HVAC energy demand.

Option C is the only choice that expressly requires treatment sufficient for the proposed potable applications. Graywater is normally directed to nonpotable uses, such as toilet flushing, irrigation, or cooling-tower makeup, because untreated graywater does not meet drinking-water standards. It may be used for potable purposes only when comprehensive treatment produces water that satisfies all applicable public-health regulations, testing requirements, and plumbing codes. Option A provides little meaningful potable-water reduction because alternative supplies are used only as backup. Option B appropriately assigns graywater to cooling-tower makeup but incorrectly directs harvested rainwater to drinking fountains without specifying potable-grade treatment. LEED v5 encourages the responsible and safe use of resources, so alternative water must be matched to an end use according to its quality and required treatment.

According to the LEED AP BD+C V4 reference guide for Healthcare, places of respite must be outdoors or located in interior spaces with views of nature, and have options for shade or indirect sun for a portion of seating spaces. The other options are either incorrect or not required by the credit. References: LEED AP BD+C V4 reference guide for Healthcare, Places of respite

A charrette is a collaborative design process that involves multiple stakeholders, such as the owner, the design team, the community, and the users. By including the public in a charrette for a new school before the pre-design phase, potential partnerships with the community can be revealed. For example, the school might share facilities or resources with a nearby library, park, or community center.This can enhance the social and environmental benefits of the project, as well as reduce costs and increase efficiency.References: LEED BD+C Reference Guide, Introduction, page 171; LEED BD+C Reference Guide, Integrative Process, page 291
