USGBC Updated LEED-AP-BD+C Exam Questions and Answers by danyal

USGBC’s vision for using LEED internationally is to promote green building practices that are globally applicable, locally relevant, and culturally sensitive1. To achieve this vision, USGBC provides opportunities for alternative compliance paths (ACPs) that meet the unique needs of a particular region, such as climate, codes, standards, market conditions, and priorities2. ACPs are modifications or additions to existing LEED credits or prerequisites that recognize regional differences and allow for more flexibility and applicability of LEED3. ACPs are developed by USGBC in collaboration with local green building councils, experts, and stakeholders, and are reviewed and approved by the LEED Steering Committee3. ACPs are available for various regions and countries, such as China, India, Brazil, Europe, and Canada2.

A compliant water meter is a device that measures and records the total potable water use of the building and associated grounds. According to the LEED v4 Reference Guide for Building Design and Construction, a compliant water meter must meet the following requirements1:

•It must be permanently installed and measure the total water use of the building and grounds.

•It must have a remote communication capability or be readable from a location that is accessible to building management.

•It must have a data storage capability of at least 18 months, or be connected to a system that can store data for at least 18 months.

•It must have a resolution of 0.5 gallons (2 liters) or less, or the smallest unit of measure that is appropriate for the expected water use of the building.

According to the LEED v4: Building Design + Construction Guide, the owner or an owner’s representative must be a member of the integrated project team for the Integrative Process Prerequisite, Integrative Project Planning and Design.The owner or an owner’s representative is responsible for establishing the project’s vision, goals, budget,and schedule, as well as defining the owner’s project requirements (OPR) and participating in the design charrettes and reviews1.The owner or an owner’s representative also plays a key role in ensuring the continuity and alignment of the project’s performance and environmental objectives throughout all phases of the project1.

The other choices are not mandatory members of the integrated project team, although they may be involved in the integrative process depending on the project’s scope and needs.The general contractor is typically hired after the design phase and may not be involved in the predesign and schematic design analyses required by the prerequisite1.A LEED AP is a professional who has demonstrated knowledge and experience in applying the LEED rating system, but is not required to be part of the integrated project team, although it is recommended and rewarded by the LEED credit, Integrative Process1.The project’s mechanical engineer is one of the possible design consultants who may contribute to the integrative process, especially for the energy-related systems analysis, but is not required to be part of the integrated project team1.

The Materials and Resources Credit, Building Life-Cycle Impact Reduction, rewards projects that reuse existing building structures and envelopes, or salvage materials from off-site or on-site sources. According to the LEED v4 Reference Guide for Building Design and Construction, the project team must calculate the percentage of building being reused by dividing the area of the existing building structure and envelope that is reused by the total area of the completed building structure and envelope1. However, the project team must exclude from the calculation any hazardous materials that are remediated as a part of the project, such as asbestos, lead, mold, or PCBs1. Therefore, the asbestos containing materials found on the perimeter walls will be excluded from the calculation, regardless of the volume.
