Surple uses time series analysis to calculate your buildings' expected energy consumption based on your historical usage patterns.
The model does more than look at your historical data. The technique is more developed than this, and over time, recognises changes to your usage patterns. More recent readings have the strongest influence, but gradual changes over time are also accounted for.
As the model automatically understands seasonal and weekly cycles, it is perfect for calculating the expected energy consumption of buildings that follow a cyclic usage pattern such as offices, schools or homes.
