Building Automation & Control

Building automation and control (BAC) systems involve a combination of hardware and software that control aspects of a building’s systems, potentially including power, lighting and illumination, access and security, heating, ventilation and air-conditioning systems (HVAC), environmental sensors, elevators and escalators, and entertainment. Benefits of building automation and control systems can include efficient control of environmental conditions, individual room control, increased staff productivity, effective use of energy, improved equipment reliability, and preventative maintenance. For example, systems can provide information on problems with building equipment, allowing for computerized maintenance scheduling as opposed to reactive identification and management of issues. Building management systems are most commonly implemented in large projects with extensive mechanical, HVAC, electrical, and plumbing systems. Building management systems (BMS) are central to BAC use cases. Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches 70% on average. BMS systems are thus critical components for managing energy demand. Improperly configured BMS systems are believed to result in the wastage of 20% of a typical building's energy usage, or approximately 8% of total energy usage in the United States.

  • Advantech: Convenience Store Energy Saving Application
    Since electricity costs keep on rising, the bills for convenience stores keep on increasing and unfortunately it’s difficult for convenience stores to raise their prices to maintain the same profit margins. Variable overheads are difficult to budget for and give accountants a headache, therefore one convenience store chain in Thailand has decided to redress the balance and put themselves in chargeof power generation by installing solar panels in their stores.Our customer wanted to reduce their energy costs by at least 10 percent and having installed solar panels in their store locations they needed to be able to send the power to where it was needed and when it was needed. Since the stores are open for 24 hours and it’s onlysunny forroughly 12 of those, it was essential that the power distribution to the lighting and refrigeration units was managed efficiently.
    relayr: Unleashing Your Data From the Digital Ceiling Ecosystem
    In the Buildings space, connecting to the data in various systems has always been difficult and complicated; controlling those systems was even harder. The number of proprietary gateways, layers of complicated technology, and disparate programming languages has made it impossible to effectively collect and analyze data or control the various systems in the building without monstrous, bloated building automation applications.

  • BUSINESS VIEWPOINT
  • 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.

     

  • STAKEHOLDER VIEWPOINT
  • TECHNOLOGY VIEWPOINT
  • 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 protocols 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 interfaces for data reporting and interaction with the BACS system.

  • DATA VIEWPOINT
  • DEPLOYMENT CHALLENGES
  • 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.
