Advanced Building Management Systems

The driver in advanced building management systems is the increasing complexity of buildings. From an equipment or hardware perspective we now have buildings with energy and sustainability systems which are relatively new for buildings, systems that even five years ago were not commonplace. These include systems such as rain water harvesting, exterior shading, water reclamation, electric switchable glass, sun tracking systems, and so forth. Maintaining and optimizing each of these new systems is a challenge, further burdening and challenging facility management. The other aspect of increased complexity is related to management decisions regarding building operations. Many of these decisions now involve several variables, with some situations requiring real-time decisions, for example a demand response event from a utility requiring immediate action.

The shortcomings of the typical legacy BMS is quite a long list, including limited integration capabilities, inadequate and elementary analytic tools, proprietary programming languages, a dearth of software applications, and legacy user interfaces.

A smart building will have an advanced building management system with an open programming language where all integration is accomplished via software. It requires middleware to normalize and standardize all data from subsystems into an open, standardized database using SOAP/XML or other computer software exchange architecture. The database would include all physical, virtual and calculated points. The user interface to the advanced systems include displays and dashboards completely configurable and customizable by users, with access via a browser. The system would be capable of data exchange with information in enterprise and business level software, providing a suite of software applications such as energy management, building performance analytics, alarm management, and automatic fault detection and diagnosis.
