LEED-AP-ID-C Exam Questions and Answers

QUESTION: 6

The project material costs for Building Product Disclosure and Optimization cost-based credits are

actual costs, furniture included
default costs, 30% of total construction cost
actual costs, furniture optional
default costs, 40% of total construction cost

Answer(s): C

Explanation:

The costs considered for Building Product Disclosure and Optimization (BPDO) cost-based credits should reflect the actual costs of the materials used in the project. Furniture is considered optional for these calculations. This approach allows for flexibility in reporting and aligns with the intent of the BPDO credits to encourage the use of sustainable materials.

Reference:

The information is based on the guidelines provided by the U.S. Green Building Council for LEED v4 ID+C MR Credits Building Product Disclosure and Optimization.

QUESTION: 7

Best practices recommend that the LEED AP confirm that minimum program requirements have been met

as part of the discovery phase
as part of the final certification submittal
after the design phase but before construction
after the Commissioning (Cx) review but before design phase submittal

Answer(s): A

Explanation:

Best practices for ensuring that minimum program requirements (MPRs) for LEED certification are met involve confirming these requirements early in the project lifecycle. Specifically, this confirmation should occur during the discovery phase, which is the initial stage of a project. The discovery phase involves beginning initial research and analysis, and when sufficient information has been gathered, a goal-setting workshop is held to discuss findings. Part of these findings should include checking that the project complies with the MPRs for the applicable LEED rating system. Confirming MPRs during this early phase helps in setting a clear direction for the project and ensures that all subsequent work is aligned with LEED's fundamental requirements, facilitating a smoother certification process.

QUESTION: 8

What should a team focus on first to significantly improve energy performance or achieve the lowest possible operation cost?

Choosing energy efficient systems
Conducting a simple box energy model
Implementing passive design strategies
Performing commissioning of energy systems

Answer(s): C

Explanation:

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.

Reference:

The LEED v4 Reference Guide for Interior Design and Construction emphasizes the importance of passive design strategies within the integrative process for optimizing energy performance. 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 design.

QUESTION: 9

A project is pursuing Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control.
Which lighting control could the design team specify to meet the credit requirements for open-office workstations?

Standard on-off switches at each workstation
Plug-in task light at each workstation that allow for on, off and a 50% light level
Overhead lighting for the open-office space with fully automatic dimming via daylight sensors for the space
Overhead lighting for the open-office space with controls that allow for on, off and a 50% light level for the space

Answer(s): D

Explanation:

To meet the requirements for Indoor Environmental Quality Credit, Interior Lighting, Option 1, the design team should specify lighting controls that enable adjustments to suit individual tasks and preferences. This includes providing controls that allow for on, off, and at least one intermediate light level, such as 50%. Overhead lighting with these controls for the open-office space would meet this criterion.

Reference:

The LEED reference guide for Interior Design and Construction provides detailed information on the requirements for lighting controls under the Indoor Environmental Quality Credit, Interior Lighting, Option 1. Specifically, it states that for at least 90% of individual occupant spaces, there must be individual lighting controls that enable occupants to adjust the lighting to suit their tasks and preferences, with at least three lighting levels or scenes (on, off, midlevel) 1.

QUESTION: 10

A tenant moving into an existing building will need to install new HVAC, power, lighting systems and other equipment.
Which of the following resources would help the tenant meet the requirements of Energy and Atmosphere Credit, Optimize Energy Performance?

Green Seal Standard 11
ANSI/ASHRAE Standard 62.1-2010
ANSI/ASHRAE/IESNA Standard 90.1-2010
South Coast Air Quality Management District (SCAQMD)

Answer(s): C

Explanation:

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.

Reference:

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 Performance.
