Last Attempt LEED-AP-BD+C Questions

Temporary wood products cannot be included in the calculations for the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices. This is because the credit only applies to permanently installed building products, not to products purchased for temporary use on the project1. The other options are false. If any temporary wood materials are included in the calculation, they must be excluded from the total value of permanently installed building products1. Non-certified wood materials do not contribute to other credits, unless they meet other criteria such as recycled content or regional materials2. FSC-certified wood materials purchased for more than one project cannot be applied to other projects seeking LEED certification, unless they are reused or salvaged materials3.

The assembly U-value of a building envelope component is the overall rate of heat transfer through that component, taking into account the different materials and layers that make up the component. For example, the assembly U-value of a wall would include the effects of the insulation, framing, sheathing, cladding, air films, etc. The assembly U-value is different from the material U-value, which is the rate of heat transfer through a single material. For example, the material U-value of steel is much higher than the material U-value of glass, but the assembly U-value of a steel-framed window may be lower than the assembly U-value of a glass curtain wall, depending on the other factors involved.

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.

Discussing the project goals to help identify the credits and options that the team should attempt is an example of developing the LEED Scorecard. The LEED Scorecard is a tool that shows the potential points that a project can achieve under each credit category of the LEED rating system1. Developing the LEED Scorecard involves selecting the most appropriate credits and options based on the project’s goals, location, budget, and design2. The scorecard helps the project team track their progress and prioritize their actions throughout the design and construction process1. References:
