shows the breakdown by energy end-use for each cluster. Key findings are that buildings in the low energy use cluster
consume roughly 1/3 of the energy as the average building in the
high energy use cluster. Process energy use is the most significant
energy end-use, followed by heating, then lighting. Cooling energy
use intensity in the high use cluster is 3 times greater that of the
low use cluster, fan and pump energy use is 2.5 times greater, and
process energy use is 3 times greater. These end-uses have a similar percentage of energy use across all clusters, suggesting that they
are codependent, and may serve as key indicators for a building’s
total energy use
