The growing focus on energy efficiency and air quality management in buildings is driving significant advancements in the smart building technology sector. In contrast, companies are increasingly investing in solutions that help track and enhance indoor air quality while optimizing energy use to address rising environmental and health concerns. Furthermore, Siemens Aktiengesellschaft introduced Connect Box in 2023, an IoT-based solution designed to oversee small to medium-sized buildings. This product, part of the Siemens Xcelerator lineup, facilitates better building management by monitoring air quality through live updates on temperature and humidity levels. It enables users to control and improve energy efficiency by providing real-time insights, which aligns well with the global emphasis on sustainable building practices. Besides this, such innovations illustrate the increasing role of IoT technology in making buildings eco-friendly and more responsive to indoor environmental quality standards. Similarly, in 2024, Bosch Sensortec launched the BME690, a 4-in-1 MEMS air quality sensor that takes energy efficiency a step further with 50% lower power consumption than its previous model. This sensor captures data on gases, humidity, temperature, and barometric pressure, designed specifically for indoor spaces, thereby supporting air quality management compliant with WELL and RESET Air standards.

Moreover, Bosch's sensor aids in creating healthier indoor environments while reducing power use by adhering to these recognized frameworks. Also, this aligns with the broader industry trend toward low-power, high-accuracy sensors capable of enhancing indoor air quality. Furthermore, these examples highlight how major companies are pushing for smarter and greener solutions to meet modern building requirements. Focusing on region-specific initiatives, Vietnam has announced plans to install 113 new air quality monitoring stations across the country by 2024. These stations will feature automated systems to track environmental conditions and health alerts more effectively, reflecting Vietnam's commitment to public health and environmental monitoring. This initiative supports Vietnam’s goal of improving public health outcomes through enhanced air quality awareness and regional assessments by gathering and analyzing extensive data on air quality. Consequently, these developments underline the global trend toward adopting advanced technologies for real-time monitoring and sustainable management of indoor and outdoor environments.
