LEED - Leadership in Energy and Environmental Design Energy and Atmosphere Credits Questions and Answers

Question 1

A new office building project is pursuing LEED BD+C certification. To meet the prerequisites for the Energy and Atmosphere (EA) category, which of the following is required?

Accepted Answer

Perform Fundamental Commissioning and Verification.

Answer

Fundamental Commissioning and Verification is a prerequisite in the LEED v4.1 Energy and Atmosphere (EA) category. Its purpose is to verify that the building's energy-related systems are installed, calibrated, and perform according to the owner's project requirements, basis of design, and construction documents. Demand response, renewable energy generation, and green power purchasing are all credits, not prerequisites, within the EA category.

Question 2

A project team is aiming to maximize points in the Optimize Energy Performance credit under LEED v4.1 BD+C. The latest update to this credit splits the points between which two performance metrics?

Accepted Answer

Energy efficiency improvement and greenhouse gas (GHG) emissions reduction.

Answer

LEED v4.1 updated the Optimize Energy Performance credit to award points based on two distinct metrics: energy efficiency improvement (which can be measured by source energy or cost) and greenhouse gas (GHG) emissions reduction. This dual-metric approach places a greater emphasis on decarbonization.

Question 3

Which of the following strategies directly contributes to earning points under the LEED EA credit for Renewable Energy in LEED v4.1?

Accepted Answer

Installing a rooftop photovoltaic (PV) array to supply a portion of the building's electricity.

Answer

The Renewable Energy credit in LEED v4.1 awards points for using on-site renewable energy systems, such as photovoltaic panels, or procuring renewable energy from off-site sources. High-efficiency HVAC systems contribute to Optimize Energy Performance, carbon offsets were part of a separate credit in older LEED versions that has now been merged, and measurement and verification is related to other credits like Advanced Energy Metering.

Question 4

A project is evaluating its options for refrigerant management to earn points in the Energy and Atmosphere category. To comply with the EA Credit: Enhanced Refrigerant Management, the project team must demonstrate what?

Accepted Answer

That the selected refrigerants have a combined Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) below a specified threshold.

Answer

The Enhanced Refrigerant Management credit aims to reduce ozone depletion and minimize direct contributions to climate change. Compliance involves selecting refrigerants and HVAC&R systems that minimize or eliminate the emission of compounds contributing to both issues, which is calculated based on their ODP and GWP values to stay below a required impact threshold. A complete phase-out of CFCs is a prerequisite (Fundamental Refrigerant Management).

Question 5

A developer is building a new data center in a region with a strained electrical grid. To support grid stability and earn a LEED credit, they decide to enroll in a program that allows the utility to temporarily reduce the building's electricity consumption during peak hours. This strategy aligns with which EA credit?

Accepted Answer

Grid Harmonization (formerly Demand Response).

Answer

This scenario describes participation in a demand response program, which is the core of the Grid Harmonization credit (referred to as Demand Response in LEED v4). This credit incentivizes buildings to be responsive to the needs of the electrical grid, helping to increase efficiency and reliability.
