To provide a healthy environment for preschool children and in response to Taoyuan City's air quality improvement plan for preschools and special education facilities, Delta joined up with Ho Tai Development Co, the agent for Daikin air conditioning, to install indoor air quality management solutions for monitoring and improving the environment in six preschools. The partnership uses Delta's UNOnext indoor air quality monitor and a management platform to monitor the indoor air quality of the preschools 24/7. When indoor air quality turns poor, Daikin's smart-linked HVAC/fresh air system kicks in to filter out the bad air. Since the installation, the 8-hour average of CO2 measured at below1000ppm in all of the classrooms and the 24-hour average of PM2.5 averaged below 35μg/m3. After the Taiwan Indoor environment quality management association (TIEQM) conducted rigorous field testing to confirm standard compliance, Delta was awarded the clean & safe certificate, which is designed especially for epidemic prevention and indoor air quality management.

Mr. Roland Chiang, general manager of Delta's Building Automation BU stated that the donated UNOnext indoor air quality monitor sports an all-in-one design that instantly monitors fine particulate matters such as PM2.5 and PM10, organic vapors, formaldehyde, ozone, carbon monoxide, carbon dioxide, temperature, humidity, and many other variables. Each indicator can be monitored and controlled in real-time through a cloud management platform and can be connected with various HVAC/fresh air systems brands. We are glad to take this opportunity to not only help preschools improve their environment but also to raise awareness of how important indoor air quality management is in the wake of the pandemic.

Delta is actively developing smart, energy-efficient, and healthy buildings. In 2019, Delta acquired a keystone membership of the nternational WELL Building Institute (IWBI) and provides corporations with relevant solutions to create more comfortable, convenient, and safe indoor environments. The preschools that participated in the Taoyuan City's demonstration plan for improving air quality include Taoyuan City Longtan Kindergarten, Yangmei Preschool, Chungli HSR Kindergarten, Bade Kindergarten, Luzhu Kindergarten, and Taoyuan Municipal Taoyuan Special School.
