Study on the Relationship between Indoor Vertical Greening and Oxygen Content in High-Rise Buildings

This article clarifies the quantitative relationship between vertical greening, indoor ventilation, and oxygen content in high-rise buildings, with aim of determining values for a high-oxygen-content threshold to assess ventilation greening buildings. The index could be provided architects assist sustainable design offers an effective, convenient, environmentally friendly oxygen-content-testing method interior spaces, while avoiding air pollution caused by current red phosphorus combustion method. Firstly, floor building Harbin was selected on-site fixed-point experiments. Secondly, through candle-burning experiment gas bottle, we measured change time before after installing as well under different states. Finally, changes relative each functional space states were statistically analyzed. results showed that there potential correlation placement buildings; this found directly related room orientation, degree plants’ photosynthesis, airflow. In general, should placed south-facing rooms. For daily two or more windows opened ensure convection rooms, which can increase their content.
