• A BAS is more like a steering wheel of a car, which lets you control the vehicle, but we don’t actually know what’s going on in the inside of the system. A BAS provides building management staff with the tools to control a building, but no information about what is going on in that building. The knowledge is mainly limited to the developers and technicians • A full upgrade into a BAS can require a significant amount of initial investment depending upon the scale of the building. • Vendor lock-in is another challenge. When a single company provides all the integrated system in a building, further adding new features often requires sticking with the existing service provider. An overlaid or retrofit system can defeat this challenge. Otherwise, the updates provided by the company may offer limited features and lack the flexibility that a building manager wants from a modern BAS. • The final challenge of using a BAS is obsolescence, i.e, a decade or two after installation, the technology used in the building will likely become out of date.
