Integrating Building Management System and facilities management on the Internet

Recently, it is of great interest to adopt the Internet/Intranet to develop Building Management Systems (BMS) and Facilities Management Systems (FMS). This paper addresses two technical issues: the Web-based access (including database integration) and the integration of BMS and FMS. These should be addressed for accessing BMS remotely via Internet, integrating control networks using the Internet protocols and infrastructures, and using Internet/Intranet for building facilities management. An experimental Internet-enabled system that integrates Building and Facilities Management Systems has been developed and tested. This system integrated open control networks with the Internet and is developed utilizing the embedded Web server, the PC Web server and the Distributed Component Object Model (DCOM) software development technology on the platform of an open control network. Three strategies for interconnecting BMS local networks via Internet/Intranet are presented and analyzed.
