A primary advantage computer-based ECS's enjoy is a dynamic display, which provides tremendous flexibility. Dynamic displays can change based on the operation that the user is carrying out, which simplifies both the user's interaction with the system and the design of the system's interface.
Dynamic displays are also capable of changing to accommodate the specific needs of a user.
Additionally, they allow graphic user interfaces, which make a program easier to understand and learn how to use. The computer's disk drive allows a computer-based ECS to provide the ability to store backups of environmental control system information permanently. This means that a sudden loss of power will not erase all of the data stored in the ECS, which can happen to a stand-alone system without a battery backup feature. A computer-based system can make use of equipment that the client already has or will be purchasing to meet other needs. In addition, for clients that spend much of their time in front of a computer, an ECS that is integrated with their computing system may represent the most accessible location for centralized control of their environment.
