Energy use intensity (EUI) is an important factor in determining energy usage. What does EUI refer to?
A: The amount of energy consumed per unit floor space
B: The total daily energy use
C: Energy consumption divided by the site area
D: The ratio of maximum daily energy use divided by the total annual energy use

参考答案: A

When a building is benchmarked, as in Portfolio Manager, one of the key metrics is energy use intensity, or EUI. Essentially, the EUI expresses a building’s energy use as a function of its size or other characteristics. For most property types in Portfolio Manager, the EUI is expressed as energy per square foot per year. It’s calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building. The user can enter the energy use information from their energy bills and Portfolio Manager automatically does the conversion to thousand British thermal units (kBtus). Generally, a low EUI signifies good energy performance.
