Indoor Air Quality

Indoor Air Quality (IAQ) is included in indoor environmental quality (IEQ). Indoor air quality intelligent monitoring system detects the carbon monoxide, carbon dioxide and other harmful gases. Indoor environmental compliance rate is 100%.

Good indoor air quality includes three kinds of controls: source, improving ventilation, air purification.

The best treatment should be made before pollution problems happen. Therefore, the first step to improve the indoor air quality is the pollution source control. If it can not be effectively controled the indoor pollution problems, ventilation is needed to improved to reduce indoor air pollutants and ameliorate the indoor temperature and humidity. If ventilation is not effective enough to provide indoor fresh air then nencessary equipments should be used for forced ventilation. In addition，some air pollutants can be removed by physical, chemicalor biochemical purification technology.

The indoor air quality of the Shanghai Tower:

PM2.5 particles can be effectively filtered. A variety of bacteria, virus, formaldehyde and other chemical pollutants as well as harmful gases in the air can be captured.

Green plants in the atriums can effectively absorb harmful gases and improve indoor air quality. Besides adsorbing dust and adjusting the temperature, humidity, the plants can also effectively reduce the noise and radiation from computers, printers, fax machines and other office equipment.
