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

Answer : B

The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will be both water efficient and high performing. The WaterSense label is a voluntary program by the U.S. Environmental Protection Agency (EPA) that identifies and promotes water-efficient products that meet EPA's specifications for water efficiency and performance. The label applies to tank-type toilets, water-using urinals, private lavatory faucets, and showerheads. For projects outside the U.S., local equivalents may be used if they meet the same criteria as WaterSense or are listed on the USGBC website. The label does not imply that the fixtures are LEED compliant, comply with mandatory federal government regulations, or comply with all international plumbing system requirements. Reference:

Answer : A

The renewable energy option is economically feasible if the present value of the utility cost savings over the lifetime of the system is greater than or equal to the present value of the higher initial cost of the system. This means that the system will pay for itself and generate net savings in the long run. The utility cost savings depend on the amount of energy produced by the solar thermal panel, the price of natural gas, and the inflation rate. The higher initial cost depends on the size, type, and installation of the solar thermal panel.

Answer : D

The Water Efficiency Credit, Indoor Water Use Reduction aims to reduce indoor water consumption by installing water-efficient fixtures and fittings, such as faucets, showerheads, toilets, and urinals1.A commercial dishwasher that is ENERGY STAR labeled or performance equivalent would help reduce the water use for dishwashing, which is one of the process water uses included in the credit calculation2. A standard garbage disposal would not reduce water use, but rather increase it. An electronic submeter at the domestic water supply pipe to the building would help measure and monitor water use, but not directly reduce it. An open-loop HVAC system that discharges potable cooling water to a nearby lake would waste a lot of water and potentially harm the environment.

To meet the requirements for EVSE compliance under LEED, the equipment must adhere to regional, state, or local standards for electrical connectors. This ensures alignment with the local codes and practices for electric vehicle infrastructure, supporting accessibility and usability of EVSE. LEED prioritizes sustainable transportation by promoting infrastructure that meets standardized requirements, enabling efficient and effective EV charging.

Answer : A

Answer : B

The Integrative Process Credit is a credit in LEED Building Design and Construction that supports high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems1.The credit requires project teams to perform analyses for both energy- and water-related systems before completing the schematic design, and to use the findings to inform the owner's project requirements, basis of design, and design and construction documents1. The example given in the question is an illustration of how selecting a paint color with a higher light reflectance value can reduce the energy use and cost of lighting fixtures, which is an energy-related system. This strategy shows how the project team applied an integrative process to evaluate the impacts of different design options on the building performance and environmental benefits. Therefore, the correct answer is B. Integrative Process Credit.

Answer : A

To comply with Indoor Environmental Quality Credit, Thermal Comfort, the standard that needs to be followed is ASHRAE 55-2010, Thermal Environmental Conditions for Human Occupancy, with errata or a local equivalent1. This standard specifies the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space2. The standard also provides methods for measuring and evaluating thermal comfort, as well as guidance for design, operation, and maintenance of thermal comfort systems2.
