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

Including the material requirements in the project specifications (D) ensures that all project team members are aware of and prioritize materials compliant with the Materials and Resources (MR) Credit: Building Product Disclosure and Optimization. Clearly defined specifications communicate the importance of sustainability criteria, such as environmental product declarations and sourcing. Whole-building life-cycle analysis (C) is part of separate LEED credits and doesn’t directly influence material prioritization by the team.

This option allows the project to comply with the minimum energy performance prerequisite by following the prescriptive recommendations of the ASHRAE 50% Advanced Energy Design Guide (AEDG) for the applicable building type and climate zone1. This option simplifies the decision making and analysis process by providing clear and specific guidance on how to achieve 50% energy savings compared to the baseline standard2. This option also reduces the need for energy modeling and documentation, which can save time and money for the project3.

When calculating the reverberation time of a room, the operating sound level of the nearest HVAC equipment is the least relevant piece of information. The reverberation time is the time it takes for the sound to decay by 60 decibels after the source stops emitting sound. The reverberation time depends on the volume and the surface area of the room, as well as the sound absorption coefficients of the materials that cover the surfaces. The height and width of the room are needed to calculate the volume and the surface area. The noise reduction coefficient of the ceiling surface and the sound absorption coefficient of the floor surface are needed to calculate the total sound absorption of the room. The operating sound level of the nearest HVAC equipment is not relevant for calculating the reverberation time, but it may affect the background noise level and the speech intelligibility in the room.
