USGBC LEED-AP-BD+C Questions Answers

According to the U.S. Green Building Council (USGBC) and U.S. Department of Energy , buildings account for approximately 40% of total energy consumption in the United States.

This includes electricity, heating, and cooling loads across residential, commercial, and industrial buildings .

Buildings are the largest energy consumers , surpassing transportation and industry sectors .

LEED emphasizes energy efficiency to help reduce this 40% energy demand .

Buildings account for 40% of all energy consumption, making Option C the correct answer.

The Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide allows projects to follow the recommendations of the ASHRAE 50% Advanced Energy Design Guides (AEDGs) for different building types and climate zones.  The AEDGs provide design guidance for buildings that use 50% less energy than those built to the requirements of the ANSI/ASHRAE/IES Standard 90.1-2004 commercial code 1 . However, not all building types and sizes are covered by the AEDGs.  According to the LEED Reference Guide for Building Design and Construction 2 , the following building types and sizes are eligible for this option:

Small to Medium Office buildings up to 100,000 ft2 (9 290 m2)

Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2)

K-12 School buildings up to 200,000 ft2 (18 580 m2)

Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2)

Therefore, among the given options, only the school project is eligible to pursue this option, as it falls within the size limit for the K-12 School AEDG 3 .

Detailed Explanation:

The project must meet the more stringent requirement, which in this case is 500 CFM (14.1 CMM) as per the local code. LEED Enhanced Indoor Air Quality prerequisites and credits prioritize compliance with the highest applicable ventilation standards to improve indoor air quality and occupant comfort.

The Basis of Design (BOD) is the document that contains the design team’s interpretation of the Owner’s Project Requirements (OPR). The BOD describes the proposed systems and how they will meet the OPR, as well as the assumptions and criteria used for the design. The BOD is a key document for the Integrative Process credit and the Enhanced Commissioning credit in LEED BD+C 1 2 .
