Pass the USGBC Leadership in Energy and Environmental Design (LEED) LEED-AP-BD+C Questions and answers with ExamsMirror

The correct answer is C. Proximity of vulnerable populations to major sources of air pollution.

According to the LEED v4.1 Reference Guide for Building Design and Construction, the Site Assessment credit requires projects to conduct and document a site inventory and analysis that covers the following topics1:

Topography

Hydrology

Climate

Vegetation

Soils

Human use

Human health effects

The human health effects topic includes identifying the proximity of vulnerable populations, such as children, elderly, or low-income residents, to major sources of air pollution, such as highways, power plants, or industrial facilities. This information can help the project team design strategies to minimize the exposure of occupants and visitors to harmful pollutants and improve the indoor and outdoor air quality of the project1.

The other options are not required for the Site Assessment credit, although they may be relevant for other credits or prerequisites. A targeted Brownfield remedy plan is required for the Brownfields Remediation credit, which applies to projects located on sites contaminated by past uses1. A historic preservation plan to include neighboring properties is not required for any LEED credit, although projects that involve historic buildings or districts must comply with local regulations and standards for preservation1. The surrounding density within a 1/4 mi. (0.40 km) radius of the project boundary is not required for the Site Assessment credit, but it is used to calculate the points for the Surrounding Density and Diverse Uses credit, which encourages projects to locate in areas with high levels of existing development and mixed land uses1.

The evapotranspiration rate is the amount of water loss in a vegetated surface in units of water depth, such as millimeters or inches. It is a measure of the water demand of the plants and the climate conditions. It is used to calculate the baseline water use for irrigation in the Outdoor Water Use Reduction credit.

According to the LEED v4: Building Design + Construction Guide, Federal Renewal Community sites are designated by the U.S. Internal Revenue Service (IRS) as areas that are eligible for tax incentives to encourage businesses to locate and hire residents within the community. These sites are considered High Priority Sites for project development, as they support the revitalization of economically distressed areas. The other federal agencies listed do not designate Federal Renewal Community sites. References: LEED v4: Building Design + Construction Guide, Location and Transportation Credit, High Priority Site, Requirements1; U.S. Internal Revenue Service, Renewal Communities2

Detailed Explanation:

Providing shade with structures that incorporate energy generation systems (e.g., photovoltaic panels) not only reduces heat island effects but also supports renewable energy credits. LEED encourages such multi-functional strategies that address multiple sustainability objectives.

The correct answer is D. critically reviewed life-cycle assessment conforming to ISO 14044. This is because:

•Option 1 of this credit requires the use of products that have environmental product declarations (EPDs), which are documents that provide information about the environmental impact of a product throughout its life cycle1.

•EPDs are based on life-cycle assessments (LCAs), which are systematic analyses of the environmental aspects and potential impacts of a product from raw material extraction to disposal2.

•LCAs must conform to the international standard ISO 14044, which specifies the principles and framework for conducting and reporting LCAs3. LCAs must also be critically reviewed by an independent panel of experts to ensure their validity and reliability4.

•The other options are not relevant for this credit. FSC certification is a label that indicates that a wood product comes from a well-managed forest5. Cradle-to-cradle certification is a label that indicates that a product is designed for circular economy, with minimal waste and toxicity. CSR is a report that discloses the social and environmental performance of a company.

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

Detailed Explanation:

The space-by-space method allows for a more precise calculation of allowable lighting power by assigning specific lighting power densities (LPDs) to each space type based on its function. This method aligns with LEED’s goal of optimizing energy performance by tailoring lighting to the actual requirements of the building’s spaces.

The Indoor Air Quality Assessment credit under LEED v4.1 BD+C rating system (Building Design and Construction) seeks to establish better quality indoor air in the building after construction and during occupancy. The credit provides two options for compliance, which cannot be combined1. Therefore, Indoor Environmental Quality test results would be required for credit compliance.

According to the LEED v4 Reference Guide for Building Design and Construction, Option 1 of the Site Development - Protect or Restore Habitat credit requires restoring 25% of the site area (including the building footprint) with native or adapted vegetation1. To achieve exemplary performance, the project must double the credit requirements and restore 50% of the site area2. In this case, the site area is 100,000 ft2 (9 290 m2), so the project must restore 50,000 ft2 (4 645 m2) with vegetation. The project already has 35,000 ft2 (3 250 m2) of native vegetated open space, so it needs to add another 15,000 ft2 (1 395 m2) of vegetation. Since the on-grade surface is fully occupied by the building footprint and the asphalt parking, the only option is to incorporate a vegetated roof. Therefore, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of 15,000 ft2 (1 395 m2).

The LEED Accredited Professional (LEED AP) plays a consultative role in helping the owner develop the Owner’s Project Requirements (OPR).

The OPR defines project goals, including energy efficiency, sustainability, and occupant comfort.

It is the owner’s responsibility to define the OPR, while the LEED AP provides guidance and technical expertise.

The design team and commissioning authority (CxA) reference the OPR throughout the project.

A LEED AP does not author, oversee, or publish the document, but ensures that LEED goals align with the project’s sustainability vision.
