Gunkiyeon Develops 'Air Quality Improvement Coating Material' to Remove Garyeongchwi

[Asia Economy Reporter Junho Hwang] A customized air quality improvement solution that can reduce carbon dioxide levels in elderly care facilities with aging odor and daycare centers with high child density has been developed. The Korea Institute of Civil Engineering and Building Technology announced on the 2nd that it developed an indoor air quality improvement solution for multi-use facilities for vulnerable health groups and successfully confirmed the improvement effect through demonstration research.

The Indoor Air Quality Research Team at the Korea Institute of Civil Engineering and Building Technology diagnosed and monitored the indoor environment of multi-use facilities to identify problems and developed customized solutions suitable for the characteristics of multi-use facilities, such as ventilation systems and naturally derived functional mineral coatings developed in-house.

They also applied this to daycare centers and elderly care facilities to conduct demonstration research. As a result, they confirmed a reduction in carbon dioxide concentration in daycare centers by an average of 38% (1175→728 ppm) and ammonia (NH3) concentration in elderly care facilities by up to 97% (1.37→0.04 ppm).

Carbon dioxide concentration is a representative indicator of indoor air pollution, and the indoor air quality maintenance standard for multi-use facilities in Korea is 1000 ppm. The WHO (World Health Organization) sets an 8-hour average of 920 ppm as the standard. Ammonia is a designated odor substance under the Odor Prevention Act, and the permissible concentration in general areas is below 1 ppm.

The research team developed and applied a functional mineral coating to reduce harmful substances and improve odors. This indoor finishing coating material, mainly composed of natural minerals, has the performance to adsorb and reduce 69% of HCHO (formaldehyde) and 98% of TVOC (total volatile organic compounds), harmful substances emitted from building materials. HCHO and TVOC are carcinogens regulated by the WHO and are known to cause sick building syndrome.

Lee Yoon-gyu, head of the Indoor Air Quality Research Team at the Korea Institute of Civil Engineering and Building Technology, stated, "We confirmed the effect through the application of customized improvement solutions according to the characteristics of daycare centers and elderly care facilities."
