A clustering framework to identify non-residential building archetypes using subsystem-level targeting

The commercial building stock is often represented through aggregated representation that do not consider the time-series profiles. It is crucial to determine the types of patterns in these profiles to provide a deeper understanding of the building’s operations. This study proposes a clustering framework that uses time-series trends to identify commercial building archetypes. The case study uses synthetic time-series data generated using US DOE building archetype EnergyPlus models. Results indicate that water heater use side outlet temperature as a feature is effective in formation of a building cluster which contains buildings that closely resemble a medium office building archetype (homogeneity score = 0.8). Stakeholders could use the identified clusters to model deep retrofits or perhaps run targeted energy-efficiency campaigns.
