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

The Whole Building Simulation option is used to meet the Energy and Atmosphere Prerequisite, Minimum Energy Performance for a hospital project. This option involves creating a detailed computer model of the building to simulate its energy performance and identify opportunities for improvement.

Furniture is the only type of product that needs to be evaluated for both VOC content and VOC emissions in the LEED BD+C Low-Emitting Materials credit. Flooring, composite wood, and wet applied products only need to meet the VOC content requirements, while other types of products, such as ceilings, walls, thermal and acoustic insulation, and exterior applied products, only need to meet the VOC emissions requirements 1 .

This option requires the project to classify wood derived fuel as a recycled material that contributes towards the credit, because it is a waste material that is converted into a useful energy source1. Wood derived fuel can be used for heating, electricity generation, or co-firing with other fuels2. According to the LEED V5: Building Design + Construction Guide, recycled materials are those that have been reprocessed or remanufactured from recovered materials3.

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

According to the LEED V5 .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 area 1 . This option rewards projects for implementing waste prevention strategies, such as designing for material optimization, prefabrication, modular construction, deconstruction, and reuse 1 . 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 area 1 . Projects must also provide a narrative describing the waste prevention measures taken during design and construction 1 .
