Question 1

What is the primary goal of energy commissioning in a new building?

Accepted Answer

Verifying that energy-consuming systems operate as designed to meet energy performance targets

Answer

Energy commissioning ensures building systems operate efficiently and as designed, achieving the intended energy performance benchmarks.

Question 2

ASHRAE Standard 90.1 is primarily referenced in US building commissioning for which purpose?

Accepted Answer

Energy efficiency requirements for buildings except low-rise residential

Answer

ASHRAE 90.1 sets the energy efficiency minimum requirements for commercial buildings and is the basis for most US energy codes.

Question 3

What is an 'Energy Use Intensity (EUI)' metric used for in building commissioning?

Accepted Answer

Quantifying a building's annual energy consumption per square foot to benchmark performance

Answer

EUI normalizes energy consumption by building area (kBtu/sq ft/yr), enabling fair comparison to similar buildings and performance targets.

Question 4

During retro-commissioning of an existing building, a commissioning agent discovers that the AHU is running at full speed 24/7 even when the building is unoccupied. What is the recommended corrective action?

Accepted Answer

Implement an occupancy-based scheduling sequence and add a VFD if not present

Answer

Implementing occupancy-based schedules and VFD control dramatically reduces energy waste during unoccupied periods.

Question 5

What does LEED's 'Enhanced Commissioning' credit require beyond fundamental commissioning?

Accepted Answer

A third-party commissioning authority independent of the design team, with additional scopes including envelope and lighting systems

Answer

LEED Enhanced Commissioning requires an independent CxA engaged early in design and expands scope to include building envelope, lighting controls, and renewable energy systems.
