With the continuously development of ventilation technology. People is able to control the indoor environment in the building and creat a comfortable indoor climate. However, In the condition of worldwide scarcity of energy, increasing pressure of energy conservation and emission reduction, deterioration of AQI(air quality index) and SBS(Sick Building Syndrome), building air ventilation draws unprecedented attention.
Requirement of ventilation design
1. On-demand of fresh airflow;
2. Balanced fresh and exhaust air system;
3. Low energy consumption,low noise and low operation cost;
4. Reasonable control system and management.
Requirement of Architectural effec
1. Ensure the efficient exhaust of indoor foul and polluted air
2. Meet the need on comfortableness of indoor people in all occasions;
3. Ensure the need of fresh air when the number of indoor staff changes.

Policy Guidance
In 2011, the Ministry of Housing and Construction and the Ministry of Health jointly organized and compiled the “Technical Specification for Evaluation of Green
Hospital Construction”.
In 2014, the government updated "Green Building Evaluation Standards"GB/T 50378-2014
