LEED-AP-BD+C Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

According to the LEED v4 Reference Guide for Building Design and Construction, the project team must conduct a waste stream audit to identify the top five recyclable waste streams generated by the building and its occupants. The audit must cover a representative time period of a minimum of 24 hours, and must account for variations in the type and quantity of waste generated by different building uses and operations. The project team must then provide dedicated areas for the collection and storage of these materials for recycling. The project team must also provide dedicated areas for the collection and storage of batteries, mercury-containing lamps, and electronic waste, or demonstrate that a local program is in place to properly dispose of these materials.

For schools intended for grades eight and below (or ages 14 and below), Option 2. Pedestrian Access requires that at least 50% of the students live no more than a 3/4 mi. (1.20 km) walking distance from a functional entry of a school building. This option aims to encourage schools to locate in areas where students can walk or bike to school, reducing vehicle trips and emissions, and promoting physical activity and health. Option 2 is available only for projects that do not meet the requirements of Option 1. Transit-Served Location, which requires access to quality transit service within a 1/4 mi. (400 m) walking distance for at least 50% of the students. References:

Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices

Natural rubber flooring is a bio-based material that can contribute to the achievement of Option 2 of the Sourcing of Raw Materials credit, which requires using products that meet at least one of the responsible extraction criteria for at least 25%, by cost, of the total value of permanently installed building products in the project1. By meeting the Sustainable Agriculture Standard (SAN), the natural rubber flooring demonstrates that it has been produced in a way that conserves biodiversity, protects natural resources, and enhances social and economic well-being2. Therefore, the cost of the substituted flooring ($80,000) can be counted towards the credit threshold.

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 Consortium for Energy Efficiency (CEE) Tier 3A standard applies to water-efficient appliances, such as dishwashers, clothes washers, and commercial kitchen equipment. It is recognized in LEED BD+C for improving indoor water efficiency.

CEE Tier 3A focuses on high-efficiency appliances that meet stringent water and energy performance requirements.

These appliances contribute to Water Efficiency (WE) credits in LEED by reducing potable water consumption.

Other options are unrelated to standard appliances for indoor water reduction:

GreenSeal pertains to environmental product certifications, including low-VOC materials.

ASHRAE 62.1-2010 relates to ventilation and indoor air quality standards.

ISO 14044-2006 addresses life cycle assessment (LCA) methodologies.

According to the LEED v4: Building Design + Construction Guide, the bicycle network must connect to a rapid transit stop that is within 3 mi. (5 km) biking distance of the project boundary. This is one of the options to meet the requirement for Option 1: Bicycle Network and Storage. The other options are to connect to at least 10 diverse uses or to connect to a school or employment center that is within 3 mi. (5 km) biking distance of the project boundary. References: LEED v4: Building Design + Construction Guide, Location and Transportation Credit: Bicycle Facilities, Option 1: Bicycle Network and Storage1

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.

Under LEED BD+C Energy and Atmosphere (EA) Credit: Renewable Energy Production, renewable biofuels must be sustainably sourced and not contaminated.

Non-mill residue forestry biomass waste qualifies as renewable biofuel because it consists of untreated wood residues from sustainable forestry operations.

Municipal solid waste is not considered renewable due to its mixed content.

Wood coated with paints, plastics, or resins is not renewable as it contains harmful chemicals.

Animal waste is not explicitly recognized by LEED as a renewable fuel.

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

Source reduction focuses on minimizing waste at its origin.

Prefabrication reduces waste by manufacturing components off-site with optimized material use, leading to less on-site cutting, packaging waste, and construction debris.

Custom design (Option A) and design-build (Option B) do not inherently reduce waste.

Material science (Option C) refers to material properties but does not directly address waste reduction.

Prefabrication is the most effective source reduction strategy, making Option D correct.
