According to Aman Taluja, Operations Head, Brightflow Engineers, indoor air quality affects health, productivity, and well-being. Maintaining optimal IAQ is crucial in large commercial spaces due to high occupancy and potential contaminants. IoT technology impacts IAQ monitoring and management, providing real-time, data-driven solutions.

The air we breathe indoors impacts our health, productivity, and well-being. In commercial spaces like offices, factories, and hospitals, maintaining optimal indoor air quality (IAQ) becomes even more critical due to high occupancy, limited ventilation, and the potential for airborne contaminants. Thankfully, advancements in Internet of Things (IoT) technology are revolutionising how we monitor and manage IAQ in these environments.

Traditionally, IAQ monitoring relied on manual spot checks with bulky and expensive equipment. This approach offered limited data points and often failed to capture real-time fluctuations in air quality. Additionally, responding to IAQ issues was reactive, leading to potential health risks and discomfort for occupants.

Rise of connected building

The rise of IoT has transformed building management by enabling a network of interconnected devices that collect and transmit real-time data. In the context of IAQ, this translates to a network of sensors strategically placed throughout a building.

These sensors can monitor various parameters, including elevated carbon dioxide (CO2) levels, which lead to drowsiness, headaches, and decreased cognitive function. They also detect volatile organic compounds (VOCs) released or outgassed from building materials, furniture, and cleaning products, which impact respiratory health. Additionally, the sensors measure particulate matter (PM) like dust, smoke, and other airborne particles that can cause irritation, allergies, and respiratory problems. Temperature and humidity are also tracked, as they influence thermal comfort and can affect mould growth or allergen activity.

Benefits of IoT-based IAQ monitoring

 IoT systems offer several advantages for IAQ management in large commercial spaces by continuously collecting and analysing data. They enable real-time monitoring, providing continuous data that allows for the immediate identification of IAQ issues and proactive interventions before these issues impact occupants. By analysing historical data, these systems offer data-driven insights that help identify trends and pinpoint areas with consistently poor IAQ, facilitating targeted solutions and preventive maintenance.

Automated ventilation systems can adjust based on real-time data, optimising energy consumption and improving efficiency by reducing unnecessary operations. Facility managers benefit from remote monitoring capabilities, allowing quicker response times and enhancing overall building management. Additionally, real-time data can create a more comfortable and healthy environment for occupants, potentially increasing productivity and reducing absenteeism.

Smart building solutions for better air

IoT technology offers data visibility and paves the way for Smart building solutions to improve indoor air quality (IAQ). Smart HVAC systems, for instance, integrate with IAQ sensors to automatically adjust temperature, humidity, and ventilation based on real-time needs. IoT-enabled air purifiers can optimise efficiency by adjusting fan speed and filter settings according to detected pollutants.

Additionally, building automation systems that integrate IAQ data with other building systems provide a holistic approach to managing energy consumption and occupant comfort.

Healthy air culture

Beyond technology, fostering a culture of awareness is crucial for maximising the benefits of IoT-based IAQ management. This involves educating employees about the importance of IAQ and its potential health impacts, encouraging them to report any discomfort or concerns. Transparent communication, achieved by regularly sharing IAQ data with employees, fosters trust and promotes a sense of control over their environment. Additionally, preventive maintenance, including regular upkeep of HVAC systems, filters, and building materials, minimises the source of potential air quality problems.

IAQ management future

 As IoT technology evolves, we expect even more sophisticated solutions for monitoring and managing IAQ. Machine learning algorithms will analyse data to predict IAQ issues and suggest proactive measures. Furthermore, integration with other Smart building technologies will create an interconnected ecosystem that optimises energy use, occupant comfort, and overall building health.


By leveraging the power of IoT technology, large commercial spaces can move beyond reactive IAQ management and embrace a proactive approach. From real-time monitoring to Smart building solutions, the connected building revolution leads to healthier, more comfortable and ultimately more productive environments for everyone.
