What are the core functions of a BACS system?
- Maintain control of the building's environment
- Operate systems according to occupancy and energy demand
- Monitor and correct the performance of systems
- Sound alerts as required
What are the facilities that may be controlled by a BACS?
Mechanical systems, plumbing, electrical systems, heating, ventilation and air-conditioning (HVAC), lighting control, security and surveillance, alarms and lifts.
What sensors are typically used to provide data into the IoT system, and which factors define their deployment?
Sensors that are low power or energy harvesting, miniature, secure and versatile lead to lower capital expenses, decreased maintenance costs and easier deployments. Data from the sensors are translated and transmitted through routers, gateways, nodes and edge computers through a myriad of proprietary and open protocols. The gateways translate and bridge protools and enable on premise control of the building through central workstations and mobile devices.
What factors define the cloud and edge platforms used to integrate?
Gateways also connect the building to the cloud through cellular or Ethernet connectivity. The cloud enables remote access, higher level analytics and communication with the grid and micro-grid.
What are the basic components of a BACS?
Sensors: Measure values such as temperature, humidity, lighting levels, room occupancy, and so on.
Controllers: Instigate the system's response from the collected data, using algorithms that apply logic and send commands.
Output devices: Carry out commands from the controller.
Communications protocol: The 'language' used by the BACS components.
Dashboard: The user interface for data reporting and interaction with the BACS system.
What business challenges could impact deployment?
Since organization structures vary, finding the optimal system and sensors to install is a great challenge. It is a case-by-case situation. Another challenge is overcoming the potential security issues that may arise and high initial investments.
