Building Automation and Controls (BAC) | Building Management System (BMS)

Building Automation and Controls (BAC) are a combination of hardware and software that control a building’s power systems; lighting and illumination; electric power and control; security, observation and magnetic card access; heating, ventilation and air-conditioning systems (HVAC); outdoor controls; lift, elevator and escalator controls; entertainment and BMS (Building Management Systems).

BAC systems provide efficient control of internal comfort conditions, individual room control, increased staff productivity, effective use of energy, improved building reliability and life, quick and effective responses to HVAC problems, and save time and money. The systems also provide information on problems in the building, allow for computerized maintenance scheduling, are easy and effective for employees to use, and easily detect problems.

Building management systems are most commonly implemented in large projects with extensive mechanical, HVAC, electrical, and plumbing systems. Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches to 70%. BMS systems are a critical component of managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.

In addition to controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for monitoring. In case a fire is detected then only the fire alarm panel could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them.

Cisco Connected Real Estate for Healthcare
Today’s healthcare executives encounter new challenges to providing quality healthcare within their budgets. The world's growing population is increasingly moving back into cities. And governments around the globe are mandating energy savings. This impacts healthcare facilities disproportionately because healthcare buildings use three to four times the energy of a typical building with the high consumption of clinical and business equipment running around the clock. At the same time, the cost of care is rising, a result of advances in the tools, treatments, and techniques used to prevent and cure disease. And yet the financial resources available for health services are limited, even in the richest nations. Hospital administrators must therefore grapple with the need to maintain or increase care levels without increasing budgets. This requires new ways of working, using labor-saving technology and more efficient workflows, and better ways to get the most out of facilities investments.
Turning A Stadium Into A Smart Building
Turning A Stadium Into A Smart Building
Honeywell created what it called the “intelligent system” for the National Stadium in Beijing, China, turning the venue for the opening and closing events at the 2008 Summer Olympics into a “smart building.” Designed by highly controversial artist Ai Weiwei, the “Bird’s Nest” remains one of the most impressive feats of stadium architecture in the world. The 250,000 square meter structure housed more than 100,000 athletes and spectators at a time. To accommodate such capacity, China turned to Honeywell’s EBI Integrated Building Management System to create an integrated “intelligent system” for improved building security, safety and energy efficiency.
Hospital Management Solution
Hospital Management Solution
The Oncology Diagnosis and Treatment Center of Brasov wanted to give patients as much freedom to roam as possible, while at the same time ensuring optimal patient safety and security. The centre was in need of an adequate wireless voice communication and messaging solution that would give patients the confi dence that medical staff is always on call, and reduce stress levels of nurses and doctors when called in case of urgent need.

The building automation system (BAS) market was valued at USD 53.66 billion in 2016 and is expected to reach USD 99.11 billion by 2022, at a CAGR of 10.73% between 2017 and 2022

What is the business value of this IoT use case and how is it measured?
Your Answer

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.

Which technologies are used in a system and what are the critical technology?
Your Answer

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, integration, or regulatory challenges could impact deployment?
Your Answer

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.
