Since the first automated buildings, sensor data was used to monitor and visualize building operations. The first automated buildings had only a few meters and sensors on the main equipment and were operated by dedicated computers in special control rooms. Modern buildings tend to have thousands of sensors down to individual desk level. The systems can now be managed remotely and mobile smart devices are on the advent of becoming primary interfaces for operation. But, the sheer amount of data that needs to be visualized adds a new layer of complexity. The tools and workflows that were designed to operate a few systems are not efficient for large buildings with thousands of sensors neither are modern apps developed to control small smart homes. The demo explores ways to visualize real-time building data on smart devices using virtual and augmented reality without specialized software requirements on devices.
