LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

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.

This alternative analysis can help the team check the impact of reducing the amount of concrete used in the building, which can affect several impact categories, such as global warming potential (GWP), acidification, and eutrophication1. Concrete is a material with high embodied energy and carbon emissions, and reducing its use can lower the environmental impact of the building2. Optimizing the slab depth can also improve the thermal performance and daylighting of the building, which can reduce the operational energy use and demand3.

Under LEED BD+C Water Efficiency (WE) credits, a public use faucet is defined as a sink or faucet that is available for general use in shared spaces, rather than being restricted to private, residential, or patient-specific settings.

School classroom sinks are used by multiple people throughout the day, making them a public use fixture.

Patient room sinks, hotel sinks, and dorm room sinks are considered private use fixtures, as they are designated for individual users or a limited number of occupants.

LEED water efficiency calculations differentiate between private and public use fixtures due to differences in water usage patterns and flow rate requirements.
