Abstract: Various of the disclosed embodiments contemplate a computer-implemented method of energy consumption and energy demand management in a building. In accordance with some embodiments, interval energy data of a specific building may be collected with a fixed time interval and paired with local historical weather data and other forms of operational data, as well as financial data including historical utility bills, utility rate structures and billing cycle dates. Paired energy interval data and the local historical weather data may be analyzed according to one or more analytic algorithms.

Abstract: The invention provides the ability to test rules in a rule-based system for configuring a product. The configuration system defines the components of a product using elements contained in a parts catalog and rules that define relationships between the components of a product. The user provides test cases that select at least one part to include in the product configuration, and the configuration tester processes the rule to determine whether the at least one part selected in the test case conflicts with the plurality of parts previously included in the product configuration.
