Developing a Campus Wide Building Information System Based on Open Standards

University campuses can significantly benefit from IoT technologies, especially from operational efficiencies and user experience perspective. Traditionally, such systems have been limited to lab based environments, where involvement of end-users is limited and the results may not reflect reality. To build IoT systems for real-world that are reliable and relevant, it is important to build experiments in real-world conditions and involve end-users. From technological perspective, there is a need for convergence of diverse fields ranging from Building Information Systems and Building Services to Building Automation Systems, IoT devices and finally the campus services that include academic and research activities.This paper outlines the efforts to develop a campus wide web based system called Otaniemi3D that provides information about energy usage, occupancy and user comfort by integrating Building Information Models and IoT devices through open messaging standards (O-MI and O-DF) and IFC models. The paper describes the design criteria and the system architecture and the workflow to generate the information needed to develop such a system.
