3.5.1 EnergyUsage
The Facility and Energy Management objects are used to report energy usage and associated environmental information; and to convey the results of the analysis of that information in standardized reports. The Energy Usage Object provides multiple information sources with the opportunity to publish time-based events containing Energy Usage data for a school building or facility. This information includes:
- Thermostat settings and outside temperature measurements from the Building Automation System
- Dynamic energy demand costs from smart meters or data from typed-in utility bill monthly spreadsheets
- Energy Usage information from shadow meters (which intercept BAS readings) from an Energy Management System
The primary goal of this object is to allow maximum flexibility in the ways in which a SIF Zone may be utilized to gather energy management data published by multiple sources, while leaving it to the Energy Analysis program (the subscriber) to take the varied data events issued in conformance with this SIF standard, and correlate them into a unified format which it can use. In general this will involve storing the information in the equivalent of an Energy Management longitudinal data system (LDS).
Please see Appendix E: Energy Management Notes for more detail about this object.
