LEED-AP-ID+C Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

Innovation Credit, Innovation, Option 3: Additional Strategies allows for the pursuit of exemplary performance in an existing LEED v4 prerequisite or credit that allows for such performance. In this case, achieving exemplary performance in the Indoor Environmental Quality Credit for Acoustic Performance can provide the additional point needed for LEED Platinum certification. This would involve surpassing the standard requirements for acoustic performance, thereby contributing to a superior indoor environment1.

 The Integrative Process Credit under LEED AP Interior Design + Construction V4 emphasizes the importance of a holistic approach that includes various phases of a project. The correct phases that should be included to comply with the intent of this credit are Discovery, Design and Construction, Occupancy, Operations, and Feedback. This approach ensures that sustainable strategies are integrated from the earliest stages of the project and continue through to post-occupancy to maximize performance and sustainability.

References: The LEED v4 Reference Guide for Interior Design and Construction provides detailed guidance on the Integrative Process Credit, highlighting the need for a comprehensive approach that spans the entire project timeline12.

For the Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 2, Leadership Extraction Practices, the total cost determination of each product includes not only the materials costs but also the transportation costs and installation labor. This is because these factors contribute to the overall expense of the product from its origin to its final installed state in the project1.

The visible light transmittance of the existing exterior glazing affects the amount of natural light that penetrates the space, which is directly related to the Indoor Environmental Quality Credit for Daylight. This credit assesses the daylighting conditions in occupied spaces to promote occupants’ comfort and well-being. Since no modifications to the building envelope are being made, the existing glazing’s light transmittance will influence the daylight credit’s performance1.

For the Materials and Resources Credit, Interiors Life Cycle Impact Reduction, Option 1. Interior Reuse, the calculation includes items that are demolished and not replaced. This is because the credit aims to encourage the reuse of interior nonstructural elements to reduce the need for new materials and minimize waste, thus contributing to a reduction in life cycle impacts1.

In the context of LEED AP Interior Design + Construction, especially under Materials and Resources Credit for Interiors Life Cycle Impact Reduction, Option 1. Interior Reuse, the aim is to encourage the reuse of interior nonstructural elements to reduce the need for new materials and minimize waste. The calculation for this credit involves determining the area of interior nonstructural elements that are reused. Items that are demolished and not replaced are included in this calculation because their non-replacement implies a reduction in the demand for new materials, thereby contributing to resource conservation and waste minimization. This approach aligns with the LEED principles of sustainable materials management and waste reduction. It's important to note that the calculation excludes elements that are not part of the interior nonstructural scope, such as exterior windows, doors, and structural floor assemblies. Hazardous materials remediated as part of the project are also excluded, as their handling is governed by specific environmental and health safety regulations.References:

For a project to achieve the Indoor Environmental Quality Credit for Low Emitting Materials, it must ensure that all materials meet the current standards. If the certifications are outdated, the LEED AP should obtain current certifications for the wall and ceiling paints to demonstrate compliance with the latest requirements. This is essential to verify that the materials used are indeed low-emitting according to the most recent standards and to maintain the integrity of the certification process123.

The ANSI/ASHRAE/IESNA Standard 90.1-2010 is the benchmark for energy efficiency in building design, providing minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. It is directly referenced in LEED v4 for the Energy and Atmosphere Credit, Optimize Energy Performance, as it sets the baseline for energy performance.

References: The LEED v4 Reference Guide for Interior Design and Construction specifically mentions ANSI/ASHRAE/IESNA Standard 90.1-2010 as a key standard for establishing the baseline for the Energy and Atmosphere Credit, Optimize Energy Performance12.

The integrative process is a strategy that can lead to both immediate and long-term cost savings. By engaging in early analysis of the interrelationships among systems, the project team can identify unique opportunities and challenges. This early engagement helps to optimize the design, which can reduce the time and cost associated with making design changes later in the project and minimize the need for change orders during construction1.

The LEED requirement for Indoor Environmental Quality Credit, Indoor Air Quality Assessment, specifies that after construction, a non-phased flush-out must supply a total air volume of14,000 cubic feet of outdoor air per square foot of floor area1. For a new office space of 36,000 ft², the calculation would be:

36,000 ft2×14,000 ft3/ft2=504,000,000 ft3

This aligns with option C, which is the correct answer.

Pre-consumer recycled content refers to materials that have been diverted from the waste stream during the manufacturing process but have not yet been used by a consumer. Sawdust from a lumber mill, which is used to make composite board, is an example of pre-consumer recycled content because it is a by-product of the manufacturing process that is being repurposed into a new product.

References: The LEED v4 reference guide for Interior Design and Construction defines pre-consumer recycled content as material diverted from the waste stream during a manufacturing process. This excludes materials that can be reclaimed within the same process they are created in1. Sawdust from a lumber mill is a waste by-product that is often repurposed into new products like composite board, making it a valid example of pre-consumer recycled content2.
