Use Cases Building Automation & Control

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.

Medanta the Medicity
Medanta the Medicity
Medanta is one of India's largest multi-super specialty institutes located in Gurgaon, India. Some of the key challenges facing Medanta included: - No Monitoring & Control over Energy Use, Indoor Air Quality, Indoor Lighting Quality & Noise Levels. - No compliance monitoring of temperature & pressure in critical care wards. - Energy bills were a surprise with no way to forecast energy costs. - Missing data & insights that could be used for targeting areas of improvement. - Existing Billing Management System (BMS) was inflexible and could not be used across the enterprise to serve the needs of different users. Requirements Based on these challenges, Medanta was looking for a comprehensive solution to Monitor & Control: - Energy Usage - Power Generators - Clean Rooms - HVAC Temperature - Chiller Temperature - Hydrant Pressure - Air Quality & Noise Levels - Critical Wards

- Multiple A/C systems to be monitored through single central monitoring system. - Monitor Status of UPS, generator and switch gear status. Both digital and analog signals. - Monitor building for low voltage conditions and power usage. - Monitor for water leak detections. - Monitor the actual operation of HVAC units to include compressor amperages, refrigerant pressures, fan and filter status. - Implement open protocol Building Automation System for future multi-vendor expansion. - Monitoring and alarming of Space Temperature within a prescribed limits. The Ernst & Young's primary concern was a power loss and high space temperatures in the both the data center and LAN rooms. The UPS or generator would start and all A/C units would cycle on and off with no delay and this would put a drain on the power supply. E&Y sought to implement an integrated system that would not only effectively monitor, but also time out and stage the A/C system restart. They were also looking for a system that allowed for future expansion of the remote alarm monitoring.
Turning Kitchens Greener and more Efficient with Building Automation
Turning Kitchens Greener and more Efficient with Building Automation
Fast food chains like McDonald's seek to manage labor and energy costs along multiple nodes of their supply chain. One place where all the challenges of running these restaurants converge is the kitchen. In fact, the kitchen is the ideal place where energy can be saved, monitored and improved. The toughest part about effecting changes in the kitchen though is the fact that these buildings are often old and difficult to upgrade.

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 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.

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.
