Under LEED EA Credit: Enhanced Commissioning, what is the primary purpose of the 'commissioning authority' (CxA) being independent from the project team?
Answer: To provide unbiased verification that building systems perform as intended
Independence ensures the CxA can objectively verify that building systems meet owner project requirements without conflicts of interest.
Which refrigerant property is most critical when evaluating the Ozone Depletion Potential (ODP) under LEED EA Credit: Enhanced Refrigerant Management?
Answer: Chlorine or bromine content in the refrigerant molecule
Chlorine and bromine atoms in refrigerant molecules are the compounds that catalytically destroy stratospheric ozone.
A building project wants to pursue LEED EA Credit: Optimize Energy Performance using the Prescriptive Compliance Path. Which reference standard does LEED primarily require for this path?
Answer: ASHRAE 90.1-2016
ASHRAE 90.1 is the energy standard LEED references for both the whole-building energy simulation and prescriptive compliance paths.
What does the term 'Measurement & Verification' (M&V) refer to in the context of LEED EA?
Answer: The ongoing process of measuring and verifying actual energy savings compared to predicted savings
M&V is the ongoing process of quantifying actual energy savings achieved by energy conservation measures against a baseline.
Under LEED v4 EA Prerequisite: Fundamental Commissioning and Verification, at what project phase must the commissioning process begin?
Answer: During the pre-design or early design phase
Fundamental commissioning must begin early in the design process to ensure owner project requirements are incorporated before major design decisions are locked in.
Which of the following LEED EA credits specifically addresses the long-term operational energy performance of a building after occupancy?
Answer: EA Credit: Advanced Energy Metering
Advanced Energy Metering requires whole-building energy metering and sub-metering of major end uses to track ongoing energy performance.
In LEED Enhanced Refrigerant Management, the LCGWP calculation accounts for which combination of factors?
Answer: Refrigerant GWP, equipment lifetime, and annual leakage rate
The life-cycle GWP calculation uses refrigerant GWP, equipment lifetime (years), and annual refrigerant leakage rate to estimate total climate impact.
