Read the first 7 (Leadership in Energy and Environmental Design Certification) Energy and Atmosphere flashcards as text

  1. In LEED v4, the Enhanced Commissioning credit includes a 'monitoring-based commissioning' path. What is a key feature of this path?

    Answer: Ongoing automated monitoring to flag system faults and inefficiencies

    Monitoring-based commissioning uses automated data collection to continuously track system performance and alert operators to faults.

  2. Which refrigerant characteristic is measured by the Global Warming Potential (GWP) metric?

    Answer: The refrigerant's heat-trapping effect relative to CO2 over 100 years

    GWP measures a refrigerant's capacity to trap heat in the atmosphere compared to carbon dioxide over a 100-year timeframe.

  3. A hotel earns points under the LEED EA Green Power and Carbon Offsets credit. What must they procure to earn this credit?

    Answer: RECs or carbon offsets from Green-e certified or equivalent sources for at least 5 years

    Green Power and Carbon Offsets requires procurement of Green-e certified (or equivalent) RECs or offsets contracted for a minimum of 5 years.

  4. What is the role of the Commissioning Authority (CxA) in a LEED project?

    Answer: To independently verify that building systems are installed and performing as designed

    The CxA is an independent party responsible for verifying that building systems are installed and operate per the Owner's Project Requirements.

  5. How does LEED v4 treat buildings that use chlorofluorocarbon (CFC)-based refrigerants in existing HVAC equipment?

    Answer: Projects must complete a phase-out or a comprehensive refrigerant reduction plan

    LEED v4 requires projects with existing CFC-based HVAC to implement a refrigerant phase-out or achieve significant reduction in refrigerant leakage rates.

  6. Which metric does LEED use to quantify the combined climate impact of refrigerant leakage over equipment lifetime?

    Answer: LCGWP (Life Cycle Global Warming Potential)

    LEED uses the LCGWP formula to account for refrigerant leakage and end-of-life loss across the full equipment lifetime.

  7. Which LEED EA credit specifically requires sub-metering of major energy end uses such as lighting, plug loads, and HVAC?

    Answer: Advanced Energy Metering

    Advanced Energy Metering requires whole-building and sub-metering of major energy end uses to enable ongoing energy monitoring and management.
