LEED (Leadership in Energy and Environmental Design Certification) Energy and Atmosphere 4

Question 1

A project team uses a whole-building energy simulation to demonstrate 20% energy cost savings over the ASHRAE 90.1 baseline. What LEED EA credit pathway are they using?

Accepted Answer

Performance rating method (energy modeling)

Answer

The performance rating method uses energy simulation software to compare the proposed design against an ASHRAE 90.1 baseline building.

Question 2

What percentage of a building's energy use must come from on-site renewable sources to earn the maximum points under LEED v4 BD+C Renewable Energy Production?

Accepted Answer

25%

Answer

LEED v4 BD+C awards maximum points for Renewable Energy Production when on-site renewables supply 10% or more, with additional points up to a project-specific maximum depending on rating system.

Question 3

Which of the following building system types is always included in LEED Fundamental Commissioning scope?

Accepted Answer

HVAC&R systems and associated controls

Answer

HVAC&R systems and their controls are always within the mandatory scope of Fundamental Commissioning under LEED EA.

Question 4

A project in a region with an active utility demand response program wants LEED EA Demand Response credit. What must they demonstrate?

Accepted Answer

Enrollment in a demand response program and the ability to reduce load by at least 10%

Answer

To earn Demand Response credit, projects must enroll in a utility demand response program and demonstrate capacity to shed or shift at least 10% of peak load.

Question 5

Under LEED v4, which path allows a smaller building to comply with the Optimize Energy Performance credit without running a full energy simulation?

Accepted Answer

ASHRAE 50% Advanced Energy Design Guide prescriptive path

Answer

LEED v4 offers an ASHRAE Advanced Energy Design Guide prescriptive path for certain building types and sizes as an alternative to full energy modeling.
