Agenda Automated Demand Response Integration Energy Initiatives & Building Management Systems Dashboarding

OpenADR What is OpenADR? 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.

OpenADR Why 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 control Set-Point relaxation Lighting Non-Critical Items

Integration Considerations for new buildings and existing buildings. Existing Buildings Migration plan from existing system Solutions for proprietary and open systems oWhen and why? Integration to other building systems Lighting Power / Energy Monitoring Fire Alarm Access / Security

Integration Cont’ Considerations when designing a new building. Life Cycle philosophy Cost over the life of the building (training, simplicity, continuous commissioning, energy savings) Integration to “other” building systems Lighting Power / Energy Monitoring Fire Alarm Access /Security

Open Systems Two primary protocols BACnet LON Certification process for both systems. ASHRAE, LonMark International. Integration to many other protocols

BACnet BACnet is a communications protocol for building automation and control networks. 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)

LON LonMark / 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.

BMS & Energy How does BMS impact Energy Initiatives BMS should play a major role in energy strategy Modern BMS is the easiest way to implement initiatives.
