Common pollutants in indoor air include carbon dioxide (CO₂), particulate matter (PM) and volatile organic compounds (VOC). Apart from ventilation and dilution method, there are currently many practical filtration and absorption methods for PM and VOC pollutants. However, most of these approaches are not applicable for reducing indoor CO₂ concentration. The introduction of vertical farming (VF) into buildings is one of the latest directions in ecological design, which can absorb CO₂ and release oxygen based on the plant photosynthesis. Office buildings are particularly suitable for integrated VF due to their spatial form, working hours and other characteristics. In this study, the effect of VF on indoor CO₂ concentration was investigated in an enclosed office. Additionally, the reduction in building ventilating energy consumption by using the VF was assessed. Results concluded that the CO₂ absorption rate of the VF vegetables can be up to 9.2 times higher than that of shade-loving landscape plants owing to higher net photosynthetic rate (NPR). And also, for a normal 30 m² office with 1–3 occupants, the indoor CO₂ concentration of a 100-plant-scale VF could be reduced by 25.7%–34.3% resulting in a reduction in building ventilating energy consumption by 12.7%–58.4% on the basis of the number of occupants and growth status of VF.

室内空气中的常见污染物包括二氧化碳（CO ₂），颗粒物（PM）和挥发性有机化合物（VOC）。除了通风和稀释方法外，目前还有许多实用的PM和VOC污染物过滤和吸收方法。然而，这些方法中的大多数不适用于降低室内CO ₂浓度。在建筑物中引入垂直耕作（VF）是生态设计的最新方向之一，生态吸收可以吸收CO ₂并根据植物的光合作用释放氧气。办公大楼由于其空间形式，工作时间和其他特点，特别适合集成VF。在这项研究中，VF对室内CO _2的影响在一个封闭的办公室里调查浓度。另外，评估了通过使用VF减少的建筑通风能耗。结果得出结论，由于较高的净光合速率（NPR），VF蔬菜的CO ₂吸收率可以比喜欢遮阳的园林植物高9.2倍。而且，对于一个正常的30 m ^2的办公室，可容纳1-3名乘客，可以将100个工厂规模的VF的室内CO ₂浓度降低25.7％–34.3％，从而使建筑物的通风能耗降低12.7％。 -基于乘员人数和VF的成长状况，为–58.4％。
