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

The Sustainable Sites Credit, Light Pollution Reduction aims to minimize the adverse effects of artificial lighting on the night sky, human health, and wildlife1. However, the credit does not apply to lighting that is required for safety, security, or emergency purposes2. According to the LEED Reference Guide for Building Design and Construction, lighting for theatrical performances is considered an emergency purpose and is exempt from the credit requirements3. Therefore, the LEED AP should inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction and does not need to be modified or compared to an alternative. Enclosing the performance areas would not reduce light pollution, but rather increase energy consumption and affect the outdoor experience. Calculating the return on investment over the 20-year life of the project is irrelevant to the credit and would not help achieve it.

To achieve the maximum number of Energy and Atmosphere points, the project team must include an energy modeler and a commissioning agent. The energy modeler is responsible for performing the whole-building energy simulation that demonstrates the energy performance improvement over the baseline building, which is required for Energy and Atmosphere Prerequisite 2 and Credit 11. The commissioning agent is responsible for verifying that the building’s energy systems are installed, calibrated, and perform according to the owner’s project requirements, basis of design, and construction documents, which is required for Energy and Atmosphere Prerequisite 1 and Credit 31. The commissioning agent also ensures that the renewable energy systems are properly integrated and functioning2. The contractor and the construction manager are not directly involved in the energy modeling or commissioning process, although they must follow the design specifications and coordinate with the commissioning agent. The facilities manager is not required for achieving the Energy and Atmosphere points, although they may benefit from the training and documentation provided by the commissioning agent. References:

A vegetated roof primarily contributes to the Sustainable Sites (SS) Credit: Heat Island Reduction. Green roofs reduce the heat island effect by minimizing roof surface temperatures through vegetation, which absorbs less heat than conventional roofing materials. This helps lower building cooling costs and mitigates urban heat effects. Sensitive Land Protection (B) and Site Assessment (C) are unrelated to roof treatments, while Light Pollution Reduction (D) deals with exterior lighting strategies.
