I will add though (in reference to the comment above), that simple alerts don’t provide adequate information. If simple alerts are set up (for temperature, etc.), then the manager will receive many alerts if the temperature drops below a given number even for a second. It is important to have a chain of alerts set up. For example, an alert if temperature drops below a certain number for a certain amount of time, then process an alert.

Building automation describes the functionality provided by the control system of a building. A building automation system (BAS) is an example of a distributed control system. The control system is a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building.

BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures and provides email and/or text notifications to building engineering staff. The BAS functionality reduces building energy and maintenance costs when compared to a non-controlled building. A building controlled by a BAS is often referred to as an intelligent building system.
