CEA Benchmarking & Energy Star Certification 5

Question 1

A retail strip mall benchmarks at a site EUI of 55 kBtu/sq ft/yr. The national median for retail is 70 kBtu/sq ft/yr. What does this suggest?

Accepted Answer

The building is performing better than the national median

Answer

A site EUI of 55 vs. a national median of 70 kBtu/sq ft/yr means the building uses roughly 21% less energy per square foot than the median, indicating above-average efficiency.

Question 2

Which section of ASHRAE Standard 100 directly supports the benchmarking process required in many municipal energy disclosure ordinances?

Accepted Answer

Section 5 – Energy Use Classification and Benchmarking

Answer

ASHRAE 100 Section 5 establishes energy use classification and benchmarking methodology that aligns with Portfolio Manager and local ordinance requirements.

Question 3

A university wants to benchmark its entire campus in Portfolio Manager. How should shared metering across multiple buildings be handled?

Accepted Answer

Use Portfolio Manager's campus aggregation feature to aggregate meters and allocate energy to individual buildings

Answer

Portfolio Manager's campus feature allows a parent campus account with aggregate meters, and individual buildings can be allocated proportional energy shares.

Question 4

What is the relationship between ENERGY STAR score and greenhouse gas emissions for a typical commercial building?

Accepted Answer

Higher ENERGY STAR scores generally correspond to lower GHG emissions per square foot

Answer

Because source energy includes the carbon intensity of the grid, higher scores (lower source EUI) generally correlate with lower GHG emissions per square foot.

Question 5

Under EPA's ENERGY STAR program, what is the 'National Median Source EUI' used for?

Accepted Answer

As the 50th percentile baseline from which the 1–100 scoring scale is calibrated

Answer

The national median source EUI anchors the 50th percentile of the scoring distribution, against which all benchmarked buildings are ranked.
