Going beyond building automation, the Building Internet of Things (BIoT) is a development which will herald in a new breed of intelligent buildings that are driving real value and greater performance for all stakeholders. This multi-faceted drive encompasses technologies in building services installations, hardware infrastructure and data connectivity. Combined with tools from big data analytics and economic, behavioral and environmental considerations, it enables better strategic decisions for building managers and property owners to consider the building in the context of smart cities and smart occupants.
