Free Practice Questions for USGBC LEED-AP-ID+C Exam

Option 2 of the Location and Transportation Credit, Surrounding Density and Diverse Uses, requires that the project’s main entrance be within a 1/2-mile walking distance of at least seven operational and publicly accessible uses. The existing fast-food restaurant without a drive-in service, being only 1/8 mi. away, meets the criteria for proximity and is considered a diverse use under this credit1.

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.

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.

 Implementing passive design strategies should be the primary focus as they utilize the climate to maintain a comfortable temperature range in the building, reducing the reliance on mechanical heating and cooling systems. This approach can significantly improve energy performance and reduce operational costs by maximizing natural heating, cooling, and daylighting before considering mechanical or electrical systems.

References: The LEED v4 Reference Guide for Interior Design and Construction emphasizes the importance of passive design strategies within the integrative process for optimizing energy performance1. Additionally, the LEED v4 energy update reflects a focus on increased energy efficiency and greenhouse gas emissions reductions, which can be effectively addressed through passive design23.

When green power is not Green-e certified, the project team can still pursue the Energy and Atmosphere Credit for Green Power by demonstrating that the purchased green power meets equivalent standards. This involves providing documentation that verifies the green power’s quality and production process align with the criteria set by Green-e certification.

References: The LEED v4 Reference Guide for Interior Design and Construction includes provisions for using green power that is not Green-e certified, as long as the project teamcan substantiate its equivalence. This can be done through third-party verification and ensuring that the energy source meets the requirements for renewable resources detailed in the current version of the Green-e standard123.

Wood derived fuel contributes toward the Materials and Resources Credit, Construction and Demolition Waste Management, as it is considered a form of waste diversion. Diverting wood waste to be used as fuel is a recognized strategy for reducing the amount of waste sent to landfills and incinerators, aligning with the goals of sustainable waste management practices outlined in LEED1.

The Water Efficiency Prerequisite for Indoor Water Use Reduction in LEED AP ID+C V4 focuses on reducing the aggregate indoor water consumption by 20 percent from the baseline. This includes water usage by appliances such as residential clothes washers and dishwashers, which are common contributors to indoor water use.

References: The LEED v4 Indoor Water Use Reduction Calculator provides guidance on the baseline water consumption for various fittings and fixtures, including residential appliances1. Additionally, the LEED v4: Interior Design + Construction Guide outlines the requirements for achieving the prerequisite, emphasizing the reduction of indoor water use through efficient appliances2.

In the Water Efficiency Prerequisite for Indoor Water Use Reduction, the focus is on reducing potable water usage through efficient fixtures and appliances. The eligible appliances that fall under this prerequisite are residential clothes washers and dishwashers, as they are commonly used appliances within buildings and contribute to indoor water use. These appliances must meet certain efficiency standards, such as being ENERGY STAR certified or equivalent, which ensure they use less water than conventional models.

In LEED, densely occupied spaces are relevant for assessing indoor environmental quality strategies, especially concerning carbon dioxide monitoring. High-density occupancy can lead to increased levels of CO2, which may affect occupants' comfort and health. Identifying densely occupied spaces is a crucial step in designing appropriate ventilation and air quality monitoring systems, and the carbon dioxide monitoring strategy aims to maintain the CO2 levels within acceptable limits in such spaces.

The LEED v4 criteria for the Energy and Atmosphere Credit, Advanced Energy Metering, Option 2 requires advanced energy metering for all whole-building energy sources as well as for any individual energy end uses that account for 10% or more of the total annual consumption of the building. From the provided energy end-use consumption data, it is clear that space cooling, interior fans, and receptacles each represent more than 10% of the total energy consumption. Additionally, interior lighting and space heating together also account for a significant portion of the energy consumption. Hence, to meet the creditrequirements, advanced metering must be installed for all these categories, aligning with option C.
