• Plug-in Electric And Hybrid Electric Vehicles

• Thermal-storage Air • Demand-side Resources

• ‘‘Smart’’ Appliances And Consumer Devices

•

• Thermal-storage Air Conditioning

• Information And Control Options For Consumers


Smart Building – Smart Grid Questions

• What are the attributes and characteristics of the connection between smart buildings and the smart grid?

• What are the applications?• What are the applications?• What is the communications interface?• How will it be addressed technically?• What could or will it mean for building owners

and facility management?


Demand Response

• Grid initiating communications; buildings acknowledging the acknowledging the signal

• Response to a demand response notification can be manual or automated.


DR Continued

• Building systems automatically respond - turning off lights and equipment, adjusting set points

• If the demand response is “anticipated” - scheduled.

• If it’s dynamic real time • If it’s dynamic real time communication

• Open standards‐based - XML, SOAP and Web services

• Standards for pricing formats/ time-of-day schedules to be established

• Requires enhanced building management systems.


Distributed Generation (DG)

• Alternative on-site energy sources

• Buildings will both energy consumer and energy consumer and potential provider

• Integration require communication and verifying of the quality of the energy provided, security and safety.


Energy Information to Consumers

• Real-time and historic data, the cost, the rate schedule the trends and the projected forecast

• Amount and cost of • Amount and cost of renewable energy sources; carbon content

• Weather forecasts• The quality and reliability of

the power Commercial customersmore granular, more technicalReporting for cap-and-trade, LEED, Energy Star or gov. req.


Plug-In Hybrid Electric Vehicles (PHEV)

• Hybrid and electric cars -futuristic

• PHEVs recharged at off peak hours -store energy transferred to the grid transferred to the grid during peak.

• Depend on when the driver wants to use the car, how much the batteries are discharged and what the time-of-day energy rate is.


Building Control Systems and Devices

• Success of the smart grid will depend on the control systems within the buildings.

• Buildings will need to • Buildings will need to integrate sub-systems,

• Provide more sensors and sub-metering.

• BACnet is identified in the first draft of operational standards


Standards and Protocols

• Draft report in September.• 77 standards/specifications • 16 standards were initially

identified having strong consensusconsensus

• Expanded to 31 after public comment

• Added 46 standards were identified as potentially applicable


Standards
