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

During preliminary energy analysis, massing and orientation are energy reduction strategies that can best help in reducing the energy load in the new building construction project. Massing and orientation refer to the shape, size, and direction of the building, which affect the amount of solar heat gain, daylight, and natural ventilation that the building receives. By analyzing the massing and orientation of the building, the project team can optimize the design to minimize the heating, cooling, and lighting energy demand, and enhance the thermal comfort and indoor environmental quality of the building. The LEED v4 Reference Guide for Building Design and Construction states that "the project team should use the results of the analysis to inform the owner’s project requirements, basis of design, and design documents"1. The other options, such as green roof, site conditions, and programmatic and operational parameters, are not energy reduction strategies, but factors that influence the energy performance and demand of the building.

According to the LEED v4: Building Design + Construction Guide, Federal Renewal Community sites are designated by the U.S. Internal Revenue Service (IRS) as areas that are eligible for tax incentives to encourage businesses to locate and hire residents within the community. These sites are considered High Priority Sites for project development, as they support the revitalization of economically distressed areas. The other federal agencies listed do not designate Federal Renewal Community sites. References: LEED v4: Building Design + Construction Guide, Location and Transportation Credit, High Priority Site, Requirements1; U.S. Internal Revenue Service, Renewal Communities2

The system boundary that a building life cycle analysis must be defined to account for is the cradle-to-grave stage, which includes the production, construction, use, and end-of-life stages of the building. This stage covers all the inputs and outputs of the building system, such as materials, energy, water, emissions, waste, and maintenance.

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.

A preventive maintenance plan is a document that outlines the procedures and schedules for maintaining the building systems and equipment. It helps to ensure that the systems and equipment are operating efficiently and effectively, and that they meet the design intent and performance goals. A preventive maintenance plan can also help to reduce the risk of failures, breakdowns, and repairs, and extend the service life of the systems and equipment. A preventive maintenance plan is especially important for improving the indoor environmental quality, as it can prevent issues such as poor ventilation, air leaks, moisture problems, mold growth, and indoor air pollution. Therefore, the project team should provide the facility manager with a preventive maintenance plan for the building, along with the necessary training and resources to implement it.

Volatile Organic Compounds (VOCs) (D) are chemicals often found in building materials, such as paints, adhesives, and finishes, and are associated with health risks, including asthma, chronic obstructive pulmonary disease, and certain cancers. VOCs release harmful gases that contribute to indoor air pollution, and LEED encourages using low-VOC materials to protect occupant health. PVCs (B) and CFCs (C) are harmful to the environment but are not directly linked to these health conditions.

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.

In LEED-certified projects, residential buildings (D) are the exception to the rule prohibiting smoking inside buildings. For residential projects, the standard is modified to require designated smoking areas with special ventilation or separation rather than a complete ban, as smoking regulations in residential settings often involve tenant rights and are treated differently than commercial or institutional buildings. LEED requires that precautions be taken to control environmental tobacco smoke migration in multifamily residential projects to protect air quality in common areas.
