A building control system that includes a post VEE readings data stores, a rules processor, weather stores, and a building controller. The stores provide tagged data sets that are each associated with a corresponding one of energy consumption streams, each of the sets having groups of contiguous interval values tagged as having been validated. The rules processor reads the stores and creates anomalies having different durations using only the groups of contiguous interval values and generates estimates for the anomalies by employing estimation techniques for each of the different durations and selects one of the estimation techniques for subsequent employment. The building controller receives post VEE readings and outside temperatures corresponding to the interval-based streams and determines and controls cumulative energy consumption corresponding to the interval-based streams and manages the cumulative energy consumption by scheduling run times for building elements that are coupled to the building controller.
