Today's building automation systems enable building systems integration and access to information from a variety of sources, e.g. fire alarm systems, access control, security systems, lighting and control systems. With the help of Internet technology and XML (Extensible Markup Language) building automation systems can also connect to other enterprise\ applications such as facility management software, maintenance management systems, ERP or financial systems. New applications are also emerging to manage energy consumption in buildings, for example demand response and fault detection and diagnosis. Systems integration and the new technologies emerging into the building systems field enable new services for building maintenance. This presentation will introduce an ongoing project where a Finnish building systems service provider is developing a process to innovate new services for building maintenance.
