OpenADR is a high level computer to computer communication protocol which was a product of the Smart Grid initiative

A way for utility suppliers to automatically and securely communicate with their customers building systems to reduce peak demand.

OpenADRWhy would a customer want to implement OpenADR?

The primary reason is to reduce cost.

Utility companies are willing to incentivize their customers to reduce the peak demand.

Title 24 requires controls and equipment to be OpenADR compatible.How does demand response impact you?You control that. Various levels of comfort controlSet-Point relaxationLightingNon-Critical Items

Show Integration PDFOpen SystemsTwo primary protocolsBACnetLONCertification process for both systems. ASHRAE, LonMark International.Integration to many other protocolsBACnet & LON are the two most widely acknowledged open protocols for Building Automation Systems

BACnet developed and certified through ASHRAE (Independent Industry Trade Standards Organization) LON developed and certified through LonMark International (Indpendent Private Organization) LonMark chip in every control device.

Both BACnet and Lon based systems have the ability to integrate to many other building automation system protocols9BACnetBACnetis acommunications protocol forbuildingautomation andcontrolnetworks. It is an ASHRAE, ANSI, and ISO standard protocol.BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems and their associated equipment. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform. Proper communication between building automation devices is critical for maximizing building energy efficiency, indoor air quality, and other aspects of "green" buildings. ASHRAE Standard 135)BACnet can be described as a software standardization10LONLonMark / LonWorks is an open protocol developed by Echelon Corporation. LonMark was conceived as a general purpose real-time control technology. Which would enable plug & play interoperability and a single tool set. LonMark products can be found in all of the major building system categories as with BACnet.Every LON device has a neuron chip manufactured by Echelon Corp.LonMark is the certifying agency that certifies the product adheres to the LonMark standards.Lon is more of a hardware standardization (Neuron Chip) and some software standardization11BMS & EnergyHow does BMS impact Energy InitiativesBMS should play a major role in energy strategyModern BMS is the easiest way to implement initiatives.Scheduling, retro-commissioning, continuous commissioning, Optimization, Demand VentilationDependent on systems controlledHVACLightingPlug LoadDashboard Public Education

Client ServerHow will I get the most out of my system over time?Interview partners and select with the intent to have a long term relationship. But have the flexibility to change course, should your needs or relatioship change.How intuitive is the system. Are there any tools that I will not have access to and have to rely on the contractor for modifications?What level can I train my staff to. Can I become independent and only call on my contractor when needed?Is the system web accessible remotely? Do I need to pay for additional software keys to access my system anywhere other than my server?What is the history of the product? Have the new products and product enhancements had a history of backward compatability? Back to training, how can I continue to educate my staff?16Thank You!
