USGBC Updated LEED-AP-BD+C Exam Questions and Answers by pia

Exemplary Performance is not available for Option 2 of Location and Transportation Credit, Surrounding Density and Diverse Uses. According to the LEED v4 BD+C Reference Guide, this credit has two options: Option 1. Surrounding Density (5 points) and Option 2. Diverse Uses (1 point). Exemplary Performance is only available for Option 1, and it requires achieving a surrounding density of at least 405,000 square feet per acre (100,000 square meters per hectare)1. Option 2 does not have any Exemplary Performance criteria, and it only requires locating the project within a 1/2-mile (800-meter) walking distance of at least seven diverse uses2. References:

Surrounding Density and Diverse Uses - LEED v4

The only stage of LEED for Neighborhood Development certification that is eligible for points under Building Design and Construction: New Construction, Location and Transportation Credit, LEED for Neighborhood Development Location, is LEED for Neighborhood Development Pilot, Stage 3 LEED for Neighborhood Development Certified Project. This is because the credit requires that the project be located within the boundary of a development that has achieved certification under LEED for Neighborhood Development (either Stage 2 or Stage 3 under the Pilot or 2009 rating systems, or Certified Plan or Certified Project under the LEED v4 rating system)1 The other stages listed in the question are either conditional approvals or pre-reviews that do not guarantee certification23 References: 1: LEED v4 Reference Guide for Building Design and Construction, Location and Transportation Credit: LEED for Neighborhood Development Location, page 460. 2: LEED for Neighborhood Development Location – Above Green 3 3: LEED v4: Building Design + Construction Guide - U.S. Green Building Council 1

The correct answer is D. Document total waste per building floor area.

According to the LEED v4.1 Reference Guide for Building Design and Construction, Option 2 of the Construction and Demolition Waste Management credit requires projects to reduce the total construction waste generated by the project to less than 12.2 kilograms per square meter (2.5 pounds per square foot) of the building’s floor area1. This option rewards projects for implementing waste prevention strategies, such as designing for material optimization, prefabrication, modular construction, deconstruction, and reuse1. To meet the requirements of this option, projects must document the total weight or volume of all construction waste generated by the project, excluding land-clearing debris and excavated soil, and divide it by the building’s floor area1. Projects must also provide a narrative describing the waste prevention measures taken during design and construction1.

The percentage of recycled content contributing to the credit is calculated based on the value of the recycled content relative to the total construction cost. The combined value of recycled content here is $1 million (post-consumer) + $1 million (pre-consumer) = $2 million. The percentage is then calculated as:

2,000,00010,000,000×100=20%\frac{2,000,000}{10,000,000} \times 100 = 20\%10,000,0002,000,000​×100=20%

Therefore, the recycled content accounts for 20% of the total material value for the project, contributing to the Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials.
