Full Description

This is part two of a paper that presents an excerpt of ASHRAE Research Project 1011-RP, "Utility/Energy Management and Controls System (EMCS) Communication Protocol Requirements." The focus of this project was on the definition of energy-related 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, and 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. This paper introduces the Common Application Service Models (CASM) as a data-modeling framework for achieving topology independence in the implementation of these services in diverse networks using a wide range of computing plat-forms. A detailed data model for a real-time-pricing rate schedule will be presented and further described by means of an example of a real-time-pricing communication. The paper concludes with a mapping approach to map data objects defined for the above services from a CASM framework to the BACnet protocol.
