Supervisory and Energy Management System of large public buildings

Buildings are important contributors to energy consumption accounting for around one-third of energy consumed in cities, where large public buildings are the dominant energy consumers and energy consumption might be significantly decreased through Building Energy Management Systems (BEMS). A supervisory and management system for energy conservation in large public buildings is presented in this paper, with a PC or a embedded computer system running a BEMS software designed to connected to distributed energy metering system, wireless sensor networks, even conventional building automation (BA) systems. The supervisory and management software consists of information inquiry, energy consumption metering, energy efficiency analysis and decision support subsystems. The system framework is introduced with development and application of the software described in detail.
