Combating air pollution with IoTand UV technology

Indoor and outdoor air pollution sources vary, with indoor contaminants often originating from combustion, building materials, and biological agents. Harsh Gupta, Manager, Blue Star, shares the mitigation methods using IoT and UV technology.

How do indoor air pollution sources differ from outdoor pollution sources?

Indoor air contaminants largely come from a variety of sources within buildings. These sources differ from outdoor pollution sources in terms of nature and behaviour. The principal sources of indoor air pollution and how they differ from outdoor ones are combustion sources, which include cooking gas, woodstoves, and tobacco smoke. Building materials, household products, and biological agents contribute to indoor air pollution.

How can IoT technology impact indoor air quality monitoring and management in large commercial spaces?

IoT advancements improve indoor air quality monitoring and management in large commercial spaces by enhancing efficiency and safety. IoT sensors enable real-time monitoring of indoor air quality (IAQ) parameters like CO2, VOCs, particulate matter, temperature, and humidity, allowing facility managers to detect deviations.

Data analysis and IoT-enabled IAQ monitoring systems can work with building management systems to provide predictive maintenance. By analysing IAQ data trends, the system can detect possible difficulties with HVAC equipment or ventilation systems before they cause IAQ problems. It allows maintenance schedules to be optimised, leading to a reduction in downtime.

IoT devices can automatically respond to IAQ issues based on predefined thresholds or conditions. For example, if CO2 levels in a conference room exceed a specific threshold, IoT-enabled ventilation systems can automatically boost circulation to improve air quality without requiring human participation. 

How can building managers optimise IAQ using filtration systems while reducing energy consumption?

Building managers who want to create healthier indoor environments must consider optimising IAQ using filtration systems while reducing energy consumption. Several tactics and technologies can help attain this balance: HEPA (High-Efficiency Particulate Air) filters, MERV (Minimum Efficiency Reporting Value) filters, activated carbon filters, and ultraviolet (UV) germicidal irradiation. 

Building managers can use appropriate filtering technology, including energy-efficient ventilation systems, and apply smart monitoring and maintenance practices. This technique improves occupant health and comfort while helping building operations and reducing costs over time.

How do advancements in UV technology improve energy efficiency and indoor air quality?

The recent advancements in integrating UV technology into HVAC systems aim to increase energy efficiency, improve disinfection efficacy, incorporate smart controls, and ensure safety and regulatory compliance. These developments make UV-C technology an effective tool for improving indoor air quality and generating healthier indoor environments in various settings, including healthcare facilities, offices, schools, and residential buildings. By using these best practices, building managers can efficiently use UV-C technology to reduce the transmission of airborne diseases and increase occupant well-being.
