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

For the Materials and Resources Credit, Building Life-Cycle Impact Reduction, Option 2. Renovation of Abandoned or Blighted Buildings, up to 25% of the building surface area may be excluded from the credit calculation due to deterioration or damage 1 .

the local equivalent standard is more stringent than ASTM E1527-05

According to the LEED V5 Reference Guide for Building Design and Construction, a Phase I ESA is required for all projects, except for those located on previously developed land that has not been used for industrial, commercial, or agricultural purposes. The Phase I ESA must follow the ASTM E1527-05 standard or a local equivalent. However, if the local equivalent is more stringent than the ASTM standard, then the project must comply with the local equivalent. Therefore, if the new building project is located in a jurisdiction that has a more rigorous standard for Phase I ESA than ASTM E1527-05, then it must complete a new Phase I ESA, regardless of the previous ESA done for the certified facility.

For the small commercial building described, the applicable requirement is whole-building energy-use monitoring for each energy source at least monthly. This establishes a basic record of electricity, natural gas, district energy, fuel oil, or other energy supplied to the building. Fifteen-minute electricity monitoring represents a much more granular interval and is not the stated minimum for this building-size condition. End-use submetering separately measures categories such as lighting, HVAC, plug loads, and service water heating and is generally associated with more extensive monitoring provisions rather than the basic small-building requirement presented here. Monthly whole-building data enables owners to benchmark performance, identify abnormal changes, compare actual use with forecasts, and support ongoing energy-management activities. Therefore, Option C correctly describes the required monitoring level.

An energy meter must be installed for hot water at the main service point for the project to meet the requirements for Energy and Atmosphere Prerequisite, Building-Level Energy Metering. According to the LEED V5 BD+C Reference Guide, this prerequisite requires that “all energy sources used by the building must be metered or submetered” 1 . The hot water from the central utility plant is an energy source used by the building, even if it is not directly paid by the office. Therefore, it must be metered at the point where it enters the building. The other options are incorrect because natural gas is not an energy source used by the building in this case, and the flat fee or the ownership of the energy source do not exempt the project from the metering requirement.

A preliminary water budget analysis should be conducted before schematic design is completed to integrate water efficiency strategies early in the project.

Option D is correct as early-stage planning maximizes efficiency.

The distance between the project site and the manufacturing location is determined by the straight line distance.  This is because the LEED V5 Reference Guide for Building Design and Construction states that the distance should be measured as the crow flies 1 . The straight line distance is the shortest distance between two points on a plane, regardless of the mode of transportation or the road conditions. The image that you sent shows the straight line distance between the project site and the manufacturing location as the line segment AB.

The bonus location valuation factor in several Materials and Resources credits under LEED AP BD+C V4 is intended to incentivize the purchase of products that support the local economy. Products extracted, manufactured, and produced within 100 miles (161 km) of the project are valued at 200% of their cost within the calculations 1 . This adds value to locally produced products and materials 2 .

Achievement of the Location and Transportation Credit, Surrounding Density and Diverse Uses may be affected by the move of the main entrance to the opposite side of the building. This is because the credit requires that the project be located within a minimum density area and within walking distance of diverse uses1. The walking distance is measured from a main functional entry of the project building to the diverse use entry1. If the main functional entry is moved, the distance to the diverse uses may change and affect the credit achievement. The other credits are not affected by the move of the main entrance, as they are based on the location of the project site, not the building entry. The Location and Transportation Credit, High-Priority Site rewards projects that are located on sites that are previously developed, infill, or adjacent to existing development2. The Location and Transportation Credit, Sensitive Land Protection rewards projects that are located on sites that do not contain sensitive land features such as prime farmland, wetlands, or habitats3. The Location and Transportation Credit, LEED for Neighborhood Development Location rewards projects that are located within the boundary of a LEED for Neighborhood Development certified plan4.

The most likely group of documents to support both Indoor Environmental Quality Credit, Thermal Comfort, and Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control is C, lighting plans, surveys of occupants, sequence of operations.

Lighting plans show the layout and type of lighting fixtures, as well as the lighting controls, such as dimmers, timers, occupancy sensors, or daylight sensors. Surveys of occupants provide feedback on the satisfaction and comfort level of the building users regarding the thermal and lighting conditions. Sequence of operations describes how the mechanical and lighting systems operate and respond to different scenarios, such as occupancy, temperature, or daylight levels.

These documents can demonstrate that the project meets the requirements for both credits, which are:

For Thermal Comfort, the project must design the HVAC systems and the building envelope to meet the requirements of ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy, or a local equivalent, and provide individual thermal comfort controls for at least 50% of the individual occupant spaces, and group thermal comfort controls for all shared multi-occupant spaces 1 .

For Interior Lighting, Option 1. Lighting Control, the project must provide individual lighting controls that enable adjustments to suit individual task needs for at least 90% of the individual occupant spaces, and provide lighting system controls for all shared multi-occupant spaces that allow occupants to adjust the lighting to meet group needs and preferences 2 .

The other groups of documents are less likely to support both credits, because:

Architectural floor plans, mechanical plans, and lamp specifications do not show the lighting controls or the occupant feedback.

Photometric plans, mechanical schedules, and lamp specifications do not show the thermal comfort design or the occupant feedback.

Surveys of occupants, photometric plans, and mechanical schedules do not show the lighting controls or the thermal comfort design.

The LEED Platinum certification requires the project to achieve exemplary performance in at least one credit that allows it, as specified in the LEED Reference Guide 1 . One of the credits that meets this criterion is the Indoor Environmental Quality Credit, which focuses on providing healthy and comfortable indoor environments for occupants. The credit has two options: Quality Views and Enhanced Commissioning. Quality Views requires the project to have windows that provide views of natural scenery or water bodies, which can enhance the well-being and satisfaction of occupants. Enhanced Commissioning requires the project to have a comprehensive commissioning plan that ensures all systems are properly installed, tested, and operated before occupancy. Both options can help reduce energy consumption, improve indoor air quality, and create a positive sensory experience for occupants.
