ASHRAE research project 1011-RP, titled "Utility/Energy Management and Controls System (EMCS) Communication Protocol Requirements" focussed on the definition of information services and the analysis of data requirements to enable these services. The following nine information services were defined, and their communication and data requirements were analyzed: (1) revenue meter reading (electricity, gas, water, heating and cooling energy); (2) quality of service monitoring; (3) real-time-pricing transmission; (4) load management service; (5) on-site generation supervisory control; (6) energy efficiency monitoring; (7) weather reporting and forecasting services; (8) indoor-air quality monitoring; and (9) dynamic demand bidding into a power exchange.

The result of the service definition and data requirements analysis is a series of proposed data object models that define a set of data and their relation to each other. These data sets are necessary and sufficient for the implementation of the proposed services. The research provides a brief discussion on a mapping approach to transfer the data object model proposed into a BACnet environment.
