It is no profound observation that commercial buildings today squander energy in a manner that is manifestly not sustainable. The proper management of building energy requires intelligent energy systems that rely on distributed generation, buildings-to-grid, responsive loads, on-line monitoring of efficiency programs, microgrids, and other forms of distributed resource management. A key challenge will be the development of distributed information technology (IT) that can coordinate and optimize the participants of such an intelligent energy system. Dr. Palensky will share his research and professional experiences in designing, developing and running distributed systems for energy information systems, data acquisition, load management and network based control. His research has spanned from tiny embedded sensor nodes up to datacenters with Oracle application servers. Below are some of the lessons learned from Dr. Palensky's research: Energy system architects should not assume that IP is ubiquitously available Conventional computer network security measures, such as Secure Socket Layer (SSL), cannot ensure security in building applications Customers unknowingly waste up to 70% of their building energy yet most of that can be solved by the appropriate application of distributed IT.
