ASHRAE, Electrical ManufacturersBegin Work on Energy Standard

Will define an “object-oriented information model

Under a national Smart Grid effort, ASHRAE and the National Electrical Manufacturers Association (NEMA) are jointly developing a standard that would provide a common basis for electrical energy consumers to describe, manage and communicate about electrical energy consumptions and forecasts.

A kickoff meeting to begin work on the proposed standard was held Aug. 30-31 at ASHRAE Headquarters in Atlanta, GA.

ASHRAE/NEMA Standard 201P, Facility Smart Grid Information Model, will define an “object-oriented information model.” The model will enable communications between appliances and control systems in homes, buildings and industrial facilities and a “smart” electrical grid. The goal is to improved the management of electrical loads and generation sources. It will also communicate information about those electrical loads to utility and other electrical service providers.

“Smart grids lead to smart meters, lead to smart systems,” says ASRHAE President Lynn G. Bellenger, P.E. “As the smart grid adjusts to suit load distribution and maintain power quality and reliability, it will communicate with building metering systems. Those systems will communicate with building systems and equipment. This ties into demand response control to reduce peak demand. One day in the future, we likely will have real-time pricing with dramatic differences in power costs dependent upon the time of day or grid load.”

“NEMA and the members of their smart grid and high-performance buildings councils see the creation of this standard as a strategic element in driving development of a nation-wide smart electrical grid while increasing energy efficiency, occupant productivity and cost-effectiveness in safe secure buildings,” adds Jim Lewis, manager, High Performance Buildings, NEMA. The standard is part of ASHRAE’s supporting efforts for the Smart Grid Interoperability Panel, a public-private partnership initiated by the National Institute of Standards and Technology to speed development of interoperability and cyber security standards for a nationwide smart electric power grid.

The proposed ASHRAE/NEMA standard will coordinate with work by the North American Energy Standards Board to develop a basic energy usage data model standard and create a facilities data model that provides additional energy usage data elements for commercial and industrial buildings. This includes lighting, heating, HVACR and other electrical loads.
