室内空气质量的研究引起了人们对居住者健康和人类福祉的严重关注，而仅仅依靠当前的通风策略可能无法完全实现这一点。室内污染物的环境暴露，如挥发性有机化合物（VOCs）和二氧化碳排放（CO2）水平，仍然是一个有问题的问题，仅通过增加通风率可能无法完全解决。植物能够清除室内污染物的活体介质可以提供一种有效的被动策略，影响居住者的健康、福祉以及建筑物的通风系统效能。尽管有许多关于园艺生物技术改善实验室环境中室内空气质量的研究，但活性植物生物过滤器或功能性绿墙在实际室内空间中的表现似乎不同，而不是在封闭的实验室中进行评估。 通过将活性植物绿墙系统作为空气过滤策略引入双层外墙，可以通过改善建筑围护结构的热性能来提高室内空气质量和建筑节能潜力。本文旨在通过对已发表结果的元分析，将生物过滤、植物空气过滤器和盆栽植物的去除效率与其空气室容积进行比较，来评估之前的结果。结果通过特定的定义指标呈现，在这些指标中，以植物种类、叶面积、时间、风量和腔室几何形状为形式的自变量被计算，以呈现不同实验条件在减少室内空气污染物方面的空间和技术影响。 本文的结论是，当植物被放置在封闭空间时，具有更高的叶面积与腔室容积比，从而提高了过滤速率，从而显示出更高的去除效率。尽管植物的潜热可能会改善围护结构的隔热性能，但风量和分层是改善围护结构热性能的更重要变量。需要进一步研究，在实地研究中以及在不同气候和建筑类型下测试封闭式植物生物过滤器的影响，以确定该策略在高性能开发设计中的适用性和优化潜力。引用:佛罗里达州奥兰多2020年冬季会议论文

Studies of indoor air quality have prompted serious concerns of occupant’s health and human well-being, which might not be fully achieved solely bycurrent ventilation strategies. Environmental exposures to indoor contaminants such as volatile organic compounds (VOCs), and Carbon Dioxideemissions (CO2) levels remain problematic issues that might not be fully addressed through increased levels of ventilation rate only. Living media whereplants are able to remove indoor contaminants can provide an effective passive strategy that impact occupant’s health, well-being, as well as building’sventilation system efficacy.Despite many studies on horticultural biotechnologies for improving indoor air quality in laboratory settings, active botanical biofilters or functional greenwalls seem to perform differently in actual indoor spaces rather than being assessed in closed experimental chambers. By introducing the idea ofincorporating active botanical green wall systems as an air filtration strategy into double skin facades, a dual benefit might be achieved to improve indoorair quality and the building’s energy saving potential by improving thermal performance of the building’s envelope. This paper aims at evaluating previousresults of biofiltration, botanical air filters, and potted plants by comparing their removal efficiencies to their air chamber volumes based on a metaanalysisof published results. Results are presented through specific defined metrics in which independent variables in the form of, plant species, leaf areas,time, air volume, and chamber geometry are computed to present spatial and technical influences of different experimental conditions in reducing indoor aircontaminants.The paper concludes that plants show higher removal efficiencies when placed in enclosed spaces with higher ratio of leave areas to chamber volumes whichalso increases the rate of filtration. Although plants’ latent heat might improve the envelope thermal insulation, air volume and stratification are moresignificant variables at improving the envelope thermal properties. Further studies are needed to test the impact of enclosed botanical biofilters in fieldstudies and under different climatic and building types to determine the suitability and optimization potential of this strategy for the design of highperformanceenvelopes.
