BUILDING MANAGEMENT SYSTEMS


E FUTURE WITH IoT TECHNOLOGY


SMART SERVERS Smart servers are revolutionising the way buildings are managed, allowing for more efficient and effective control of HVAC and lighting systems. By directly interfacing with existing infrastructure, these servers offer a smooth integration into buildings without the need for extensive and costly retrofitting. Smart servers designed specifically for IoT applications are providing exceptional benefits to building managers looking to optimise their facilities. This system goes beyond simple reporting


and dashboard functions because it actively manages buildings to reduce energy waste and improve overall performance. With the ability to automate lighting and HVAC controls in line with sensor data, building managers can achieve significant energy savings and improve the comfort of occupants. Plus, when the sensors and smart server


seamlessly integrate into existing Wi-Fi networks, it eliminates the need for additional gateways or infrastructure. This makes the roll-out process significantly smoother and more cost- effective, as there is no need to install new hardware or run additional cables. Instead, the system utilises existing Wi-Fi access points to connect and communicate with the building’s lighting and HVAC systems. This innovative approach allows building managers to quickly and easily deploy the system, minimising disruption to day-to-day operations. As a result of this, facilities can achieve the


benefits of a smart building without the typical expense and time associated with a full-scale upgrade. This helps transform existing buildings into smarter, more sustainable facilities,


Smart servers are revolutionising the way buildings are managed, allowing for more efficient and effective control of HVAC and lighting system


without the need for major renovations or costly infrastructure upgrades.


ENERGY HARVESTING Why is it important to use self-powered sensors that don’t need cables or batteries for a sustainable IoT system? Both powering methods have a significant impact on our environment. The production of wires requires mining and processing of materials, which can cause environmental damage and pollution. The installation of wired sensors also requires significant resources and energy, particularly if it involves digging or excavation. The production and disposal of batteries releases harmful chemicals into the environment, such as lead, cadmium, and mercury. These chemicals can contaminate soil


and water, posing a threat to human health and wildlife. Additionally, batteries take a long time to decompose, adding to the growing problem of electronic waste. Furthermore, the energy required to manufacture and transport batteries also contributes to greenhouse gas emissions and climate change. And let’s not forget to mention the high effort and cost of changing the batteries on a regular basis. Wireless and battery-free sensors are not


only a more sustainable solution, but they are also more cost-effective. They use energy harvesting to gain energy, which is the process of capturing and storing energy from the surrounding environment, such as light, temperature, or motion. This means that these sensors do not require batteries or wiring. Energy harvesting has a number of advantages


over traditional battery-powered sensors. First, it eliminates the need for expensive and environmentally harmful batteries, reducing the overall cost and environmental impact of the sensors. Second, it allows the sensors to be more flexible and adaptable, as they can be placed in locations where it would be difficult or impossible to run power cables or replace batteries. Finally, it allows the sensors to operate indefinitely, reducing the need for maintenance and replacement over time.


A SUSTAINABLE SOLUTION Solutions that use wireless and battery-free radio sensors mean businesses can reduce their energy consumption and costs in a sustainable manner, while also improving the working environment for employees. At the same time, they can reduce the carbon footprint of their buildings.
