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

For the Water Efficiency Credit, Indoor Water Use Reduction calculations, all fixtures within the LEED project boundary must be included, both new and existing. The baseline for the existing fixtures should be the same as the baseline flush/flow rates used for the new fixtures. This approach ensures a consistent and fair comparison between the current and proposed water use.

According to the EPA’s hierarchy, source reduction is prioritized because it addresses the environmental impacts of materials across their entire life cycle. This includes the extraction of raw materials, manufacturing, distribution, usage, and end-of-life management, including recycling and disposal. By reducing the amount of material used, source reduction minimizes the environmental footprint throughout the entire process.

References: The explanation aligns with the principles outlined in the EPA’s waste management hierarchy, which emphasizes the importance of source reduction as the most preferred approach to managing materials and waste streams12. This is also consistent with the sustainable materials management strategies detailed in the LEED v4 Reference Guide for Interior Design and Construction3.

Integrated decision-making involves the collaborative effort of various stakeholders in a project, from its conception through completion, to ensure the building's design serves its intended purpose effectively. In the context of placing circulation near the office perimeter next to the window wall, integrated decision-making would mean making design choices that enhance the building's performance and occupant comfort. Option A, installing blinds to increase occupant comfort, would address issues such as glare and thermal gains from the sun, which directly impact the occupants' comfort and the building's heating and cooling loads. This decision would emerge from the iterative process of identifying the unique needs and challenges of the project and making early design decisions that benefit the project both in execution and operation.

 Advanced Energy Metering is the credit that works synergistically with the Energy and Atmosphere Credit, Enhanced Commissioning. This is because Advanced Energy Metering involves the implementation of submetering systems that provide data on the building’s energy use. This data is crucial for the ongoing commissioning process to ensure that the building’s systems are operating as intended over time. The data helps in identifying opportunities for energy savings and ensures that energy conservation measures continue to perform optimally12.

In an Integrative Process project approach, it is essential for all principal project team members to be present at a goal-setting workshop. This includes not just the design team, but also the owner, contractor, and other key stakeholders. The integrative process is collaborative and requires the input and expertise of all principal team members to set goals that are informed by each discipline’s perspective, ensuring a holistic approach to the project1.

For the LEED AP ID+C V4 Materials and Resources Credit, under Interiors Life Cycle Impact Reduction, Option 1: Interior Reuse, hazardous materials that are remediated as part of the project must be excluded from the calculation. This ensures that the assessment of reused materials does not inadvertently promote the retention of hazardous substances in the interior space.

References: The information is based on the guidelines provided by the U.S. Green Building Council, specifically for the LEED v4 Interior Design and Construction rating system, which outlines the exclusion of hazardous materials from life cycle impact calculations1.

Incorporating a strategy where the tenant purchases energy from the building owner’s campus facility that produces renewable power to Green-e standards can contribute towards earning a LEED credit. This is because it supports the use of renewable energy, which is a key component of LEED’s sustainable energy criteria.

References: The LEED v4 reference guide for Building Design and Construction outlines that strategies involving renewable energy procurement, especially when it adheres to recognized standards like Green-e, can help in achieving LEED credits related to energy sustainability1. Additionally, the LEEDuser forum discusses the importance of binding tenantsales and lease agreements in pursuing additional credits, emphasizing the role of tenant agreements in meeting technical credit requirements2.

To achieve the Owner’s Project Requirements of a 45% reduction in indoor water usage, the strategy should focus on reducing process water demand. This can be done by evaluating the efficiency of kitchen and laundry equipment and optimizing their operational schedules to minimize water use. This approach targets water-intensive processes within the building, offering a significant opportunity for water savings.

References: The LEED v4 Reference Guide for Interior Design and Construction outlines strategies for reducing water use, which includes optimizing process water use as a means to achieve water efficiency within a building12.

 To achieve the Materials and Resources Credit for Building Product Disclosure and Optimization - Material Ingredients, a product can demonstrate material ingredient optimization through the GreenScreen v1.2 Benchmark. This method involves a screening processto assess the hazards of chemicals used in products and aims to reduce the use of chemicals that are harmful to human health and the environment1.

For LEED projects, the commissioning (Cx) process is critical to ensure that all building systems are designed, installed, tested, and capable of being operated and maintained according to the owner's operational needs, including energy efficiency and sustainability goals. If a photovoltaic (PV) system is installed after the initial commissioning process has been completed, it is essential for the original Commissioning Authority (CxA) to return and either conduct or oversee the commissioning of the newly installed PV system. This ensures that the PV system is integrated properly into the building's overall energy management strategy and that it performs according to design specifications, contributing to the building's energy efficiency and sustainability goals as outlined in the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification.References:
