ABSTRACT: Energy Information Systems (EIS), which can monitor and analyze building energy consumption and related data throughout the Internet, have been increasing in use over the last decade. Though EIS developers describe the capabilities, costs, and benefits of EIS, many of these descriptions are idealized and often insufficient for potential users to evaluate cost, benefit and operational usefulness. LBNL has conducted a series of case studies of existing EIS and related technology installations.
Introduction: This paper begins with a summary of background research and a definition of Energy Information Systems. The main part of the paper is a case study of the use of an EIS at a large campus. The case study includes a description of the system, daily operations and findings from the EIS, energy savings, and a cost-benefit analysis. It is followed by a short description of case studies of technologies related to
