5 Ways IoT Is Reshaping Smart Building Automation
Complete autonomous control of an entire facility is the goal that any modern automation system attempts to achieve. The distributed control system - the computer networking of electronic devices designed to monitor and control the mechanical, security, fire, lighting, HVAC and humidity control and ventilation systems in a building or across several campuses.
The Building Automation System (BAS) core functionality is to keep building climate within a specified range, light rooms based on an occupancy schedule, monitor performance and device failures in all systems and provide malfunction alarms. Automation systems reduce building energy and maintenance costs compared to a non-controlled building. Typically they are financed through energy and insurance savings and other savings associated with pre-emptive maintenance and quick detection of issues.
A building controlled by a BAS is often referred to as an intelligent building or "smart building". Commercial and industrial buildings have historically relied on robust proven protocols like BACnet.
Global building automation system market is estimated to reach USD 73 billion by 2026, registering a healthy CAGR of 10.6% in the forecast period of 2019-2026. This rise in market value can be attributed to rising demand for the automation of security systems in building and technological developments.

How Building Automation Systems Work
Building automation systems control various components within a building's structure, such as heating, ventilation, air conditioning (HVAC). HVAC system performance and sustainability is key for today's building operation.
The primary goal of this type of infrastructure is to improve system efficiency, reduce costs and increase safety. A centralized building management platform brings all of these parts together, but this description is a simplification of what's really going on behind the scenes.

How IoT Is Reshaping the Building Automation System Sector
Amid mounting pressure for energy efficiency and complex demands from a new generation of tech-savvy tenants, the BMS sector is due for a makeover. But it would be a grave mistake to think that modernizing legacy BMS inevitably costs you a fortune. With the proliferation of IoT technologies, you can tap into boundless possibilities to optimize property operations without incurring outrageous costs.
1. Hassle-free BMS Upgrades for Extended Functionalities
2. Greater Utility Savings to Reduce Costs and Environmental Footprint
3. 360-View Facility Management
4. Improved Tenants/Occupants’ Wellbeing and Satisfaction
5. New Revenue Generation Opportunities
Main Components of a BAS
Building Automation Systems can be implemented either during initial construction or through a retrofitting process for an existing structure. It uses five component categories to provide a smart building environment.
- Sensors:
These devices track temperature, humidity, the number of people in a room, the lighting level and other values. The sensors transmit this information to centralized controllers.
- Controller:
This component acts as the "brain" of the BAS. It collects data from the sensors and then sends commands to HVAC units, lighting systems, security alarms and other connected parts.
- Output devices:
Once the controller sends out a command, actuators and relays go into action to follow the requirements. For example, they can reduce or increase the heating in a particular part of the building, dim lights in unused offices, or turn on the air conditioning before people come to work.
- Communication protocols:
The BAS uses a specific language that's understood by the system's individual components. BACnet and Modbus are the most commonly used options.
- Terminal interface:
Users can interact with the BAS through this interface. It presents information so that users can monitor the condition of the building or choose to override settings manually.
What are the benefits of a Building Automation System?
A modern BAS equipped with appropriate meters and sensors conveys benefits in three main categories: comfort, financial, and environmental.
Comfort Advantages
In terms of tenant comfort, the most obvious benefit from a BAS is temperature regulation. By automating HVAC systems, a BAS can help to avoid frigid and sweltering mornings in the winter and summer, respectively, by powering up temperature control systems before anyone arrives and turning them down after everyone leaves.
Financial Advantages
A correctly used BAS will generally pay for itself over time in lower utility bills alone. According to one estimate, simply monitoring occupancy and allowing the BAS to adjust HVAC use accordingly results in savings between 10 and 30 percent. Reductions in peak load and other energy use benefits serve to further decrease utility costs.
Environmental Advantages
While environmental advantages don’t generally accrue to the building owner directly, as noted above, they can serve to make a property more desirable. Many owners also have a personal interest in maintaining a portfolio of energy efficient buildings.
