LEED (Leadership in Energy and Environmental Design Certification) Energy and Atmosphere 3

Question 1

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

Accepted Answer

Ongoing automated monitoring to flag system faults and inefficiencies

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

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

Answer

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