Since the emergence of automation and intelligent technology driven by the Internet of things, the whole value chain of buildings and infrastructure has undergone revolutionary changes, although the traditional building management and control industry has made slow progress in implementing and matching the pace of innovation. Due to climate change, energy demand and the changing labor force of millennials, the demand for intelligent buildings driven by the Internet of things is unprecedented.
The owners and managers of buildings gradually realize that the maximum value of buildings is determined by the occupants. Now, we have shifted our focus to the buildings that are tailored for the residents, which is the great advantage of intelligent buildings. Intelligent building technology brings many benefits to owners and managers, such as remote control and energy efficiency. It also provides residents with a better experience than other buildings. The possibility of this technology is huge. The future buildings, especially the commercial real estate, will become the most intelligent and closely connected buildings in the IOT ecosystem.
So, what is the Internet of things? How can traditional building automation benefit from it?
In short, the Internet of things is a concept, in which any device can connect to other devices and the Internet – it is essentially the network of all things connected to the Internet, so data can be obtained and collected from all these connected objects, and they can communicate with each other. These devices are equipped with sensors and then connected through a public network. Sensors help collect data, which is then used to gain insight through data analysis.
The traditional building management system works on the computer system, which can manage and track the control of the building, reduce energy consumption and ensure that the facility manager can handle the operation better. However, the traditional building automation system and various control systems (such as HVAC, security, lighting, etc.) are independent and isolated from each other. The data collected from all of these systems is not integrated, so it is difficult for facility managers to fully understand the efficiency of buildings. Since traditional systems have no elements for data analysis, the responsibility for data analysis lies with the facility team. This means that analyzing the complex data in the excel worksheet after the excel worksheet can be time-consuming and prone to human errors. Traditional systems can only collect data to automate some operations, but cannot optimize performance.
Advantages of Internet of things
In the building automation / management system (BAS / BMS) with the function of Internet of things, data from all kinds of sources are concentrated in one place even from outside the scope of the building to ensure the analysis.
For intelligent buildings, the Internet of things collects and analyzes data collected from a variety of intelligent devices, which monitor energy consumption and usage. Based on these data, the system can determine the best course of action to ensure energy efficiency and occupant comfort. For example, sensors detect that certain areas are uninhabited and can communicate with switches to turn off lights and air cooling systems in that area. Similarly, the air quality sensor can detect the rise of CO2 content and communicate with the HVAC system to use external air to clean the air inside the office. When certain patterns are repeated at a specific time, the building can also learn the behavior of the occupants. For example, if more than 20 people gather in a meeting room at a specific time every Monday for a meeting, the technology can prepare in advance by increasing the ventilation of 20 people and keeping all the lights on. This technology makes the building intelligent and intuitive, and saves energy at the same time. The improvement of efficiency can recover the investment within 1-3 years!
The future is connected
According to memoori’s research, the global building networking market (now known as Biot) will grow from US $34.8 billion at the end of 2017 to US $84.2 billion in 2022, with a compound annual growth rate of 19.4%. In addition, according to a survey conducted by Deloitte as part of its 2020 commercial real estate (CRE) outlook, most CRE executives say that the Internet of things and artificial intelligence can reduce costs and improve operational efficiency. They acknowledge that the tenant experience is not the only factor in implementing the Internet of things in buildings. Facility managers, owners, operators or developers can save 30% to 50% of their energy.
Deloitte also pointed out that the Asia Pacific region will soon invest the most in intelligent building projects, mainly due to the acceleration of urbanization and the development of green and sustainable development. According to the survey, the share of Biot revenue in the Asia Pacific region is expected to increase from 34% in 2017 to 36% by 2022.
The use of intelligent technologies such as the Internet of things and cloud computing is a driving force of the green building movement. As IOT driven buildings reduce energy consumption and become more sustainable, they are becoming one of the most environmentally friendly options for all stakeholders. According to world green building trends, 55% of Indian respondents expect that more than 60% of their projects will be green by 2021. Intelligent building automation system driven by Internet of things will play an important role in this green future.
Therefore, in terms of building automation system, the Internet of things will change the rules of the game. The Internet of things can make the building management system become an intelligent entity, which can respond to the changing situation and predict the next development. The future of buildings lies in their connectivity.
