US Green Building Council LEED AP Building Design + Construction Exam Practice Test

Answer : C

The Location and Transportation (LT) Credit: Bicycle Facilities requires short-term bicycle storage to be within 100 feet (30 meters) of a main entrance to ensure convenient access for visitors or short-term users. This credit encourages alternative transportation methods by making bicycle storage easily accessible, thereby reducing vehicular dependency. Other locations like bicycle networks or shower rooms may be relevant for long-term storage or end-of-trip facilities but are not specifically mandated for short-term storage.

Answer : D

LEED requires that at least 50% of a building's annual electricity consumption be offset by green power or carbon offsets to achieve the Energy and Atmosphere Credit: Green Power and Carbon Offsets. For this building with a projected annual consumption of 2,200,435 kWh, half of this amount, 1,100,218 kWh, must be purchased from green sources to meet the credit requirements. This strategy helps mitigate carbon emissions by promoting the use of renewable energy.

Answer : A

Reducing the envelope load involves minimizing the heat that enters or escapes through a building's envelope (walls, windows, roof, etc.). Summer solar shading is an effective strategy to block direct sunlight during warmer months, decreasing the cooling load on the HVAC system. This method helps reduce solar heat gain, which lowers energy usage for cooling. Other options like maximizing daylighting (B) increase natural light but may also increase heat gain, and decreasing the opaque wall area (C) can actually increase energy loss. Economizers (D) are HVAC strategies and don't directly reduce the envelope load.

Answer : B

Changing lighting fixtures in a conference room can affect multiple LEED credits. For LEED AP ID+C certification, the Energy and Atmosphere (EA) Credit: Optimize Energy Performance and the Indoor Environmental Quality (IEQ) Credit: Interior Lighting are directly impacted, as updated lighting can improve energy efficiency and provide better control over light quality. Improved fixtures may optimize energy use, helping to achieve credits in energy performance. Additionally, achieving better interior lighting quality can positively influence occupant well-being.

Answer : D

The document that details ideas, concepts, and criteria that are essential for a building's success is the Owner's Project Requirements (OPR). The OPR outlines the goals, expectations, and criteria from the owner's perspective, setting a foundational vision for the project. It is used in LEED AP ID+C certification as a guideline for aligning design and construction decisions with the owner's objectives. The Basis of Design (BOD) then takes the OPR's high-level goals and translates them into technical requirements. Both documents support integrated project delivery by helping ensure design aligns with the owner's goals, but the OPR specifically details what the owner considers essential.

Answer : B

Prefabrication is a source reduction strategy that can help eliminate waste produced by a project. It involves the production of components in a factory before being transported to the construction site for assembly. This method reduces waste as it allows for precise measurements and controlled conditions, minimizing the amount of excess material produced.

Answer : C

The commissioning (Cx) agent must have completed the commissioning process activities for a minimum of two similar projects in order to meet the minimum qualifications for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. This is stated in the LEED v4 Building Design + Construction Guide, under the section ''Energy and Atmosphere Credits Overview''. The guide also provides examples of similar projects that can be used as references for commissioning.
