Specifications for the Future Building Management System (IBMS)
Some innovative medium-sized companies around the globe have made the first significant steps in providing building management systems that are beginning to meet today's challenges in building operations. What follows is a list of essential functionality of an IBMS:
The platform for the IBMS must be similar to that of smartphones and tablets. The base IBMS platform will have an operating system, much like laptops and smartphones where third parties provide the applications. That model is familiar and comfortable.
The base operating system for the IBMS will do the heavy lifting: acquiring data from different building systems, standardizing or normalizing the data into an open or standard database, possibly using something like XML/SOAP. This is extensive middleware, where the operating system can deal with the BAS communications protocol standards and data formats, as well as nonstandard data (i.e., some PLCs), with the BMS fully integrated into other facility management systems, such as work order systems, asset management, maintenance systems, inventory systems, and incorporating data from BIM files.
The IBMS must allow third-party applications for specific manufacturer equipment. Given that, every company that manufactures a valve, fan coil, sensor, or roof top unit will create an app for their equipment, much like they have for product objects in BIM. These apps are likely to be much richer in monitoring and managing the equipment and will create a burgeoning marketplace.
Third-party analytic software applications to optimize building performance are critical as they keep high performance buildings at peak performance and provide a rationale for similar analytics in many other building systems. Applications that can consolidate functions across systems, such as alarm management and master scheduling will become popular. Building managers will be able to test, compare, and choose the applications they need from a variety of third-parties.
The integration capabilities of the IBMS must be extensive. It has to go beyond typical fire, HVAC, access control, and elevator integration, and progressively integrate any building system, including the smart grid and external data such as weather and the financial metrics of energy markets.
The IBMS must be an open and secured system. It requires the tools that program the IBMS be transparent so that the building owner has choices in configuring, maintaining, and programming the IBMS. System security, which is almost nonexistent on traditional BMS, is a must on an open IBMS and probably best dealt with via IT security appliances and software.
The IBMS must be able to data mine and learn a person's use of the IBMS to identify their preferences along with data important to that user. Each dashboard is meant to convey important information and key indicators, and requires an examination of the needs of individual and group audiences. IBMS analysis of users' routines, usage, and interactions with
