Architectural Engineering Test 1 Practice

Energy Use Intensity is about how much energy a building uses relative to its size over a year. It is defined as annual site energy consumption divided by the building’s floor area, with units of kBtu per square foot per year. This normalization by floor area lets you compare buildings of different sizes and occupancies on a common basis, since raw energy totals can be misleading for larger or busier buildings. EUI is a practical benchmark: you can set targets, track improvements from design choices or retrofit work, and monitor performance over time. It supports informed decisions in design and operations and is widely used in building certifications and performance programs. Remember, EUI measures energy consumption per area, not energy cost or peak power demand, and not energy use per occupant.
