Creating Smart Campus with BMS Systems:
Real-time Monitoring and Control of HVAC Systems
to Maximize Energy Efficiency and Sustainability

Solutions

In this project, our partner ADEEB Group, has successfully deployed IoT solutions designed for the university in Abu Dhabi, transforming into smart buildings in campus. The deployed system monitors the occupancy of the space with the help of VS121 AI Workplace Occupancy Sensor and control the operation of the area as per the feedback received from the AM103 3-in-1 IAQ Sensor. By monitoring CO₂, temperature and humidity in real time, the facility manager can have more accurate data on the environment. For example, during the school day, when the occupancy sensor detects that an area is occupied and the CO₂ concentration value reaches a threshold, facility managers can be informed and adjust the HVAC system accordingly. In this way, the comfort of students and staff can be better guaranteed. Alternatively, when a “ghost room” is present, occupancy sensors will report that the room is “vacant,” thereby notifying staff. As a result, lights and air conditioning can be turned off to avoid unnecessary waste, while also freeing up the use of the room for more people in need.

Having the appropriate source of data is incredibly important as not all will provide the same accuracy and quality. Embedded AI algorithm, AI Workplace Occupancy Sensor is able to accurately realize counting with up to 98% high accuracy. The accuracy gets enhanced with continuous deep learning. With 3-in-1 IAQ Sensor, real-time and accurate data is available. This is suitable for bench-marking and developing ventilation, filtration, and other indoor air quality management strategies.

Given that Milesight UG65 Semi-Industrial LoRaWAN® Gateway supports for BACnet/IP, real-time data can be seamlessly integrated into existing Building Management System (BMS). Here, LoRaWAN® serves as data channel to the control applications without any changes to BACnet protocol network. All data collected by AI Workplace Occupancy Sensor and 3-in-1 IAQ Sensor are then sent to BMS system as BACnet points. Additionally, a UG67 Outdoor LoRaWAN® Gateway is located at the top of the building, acting as a master (in fleet mode) and providing a backup cellular connection to the Internet.
