Abstract

The article deals with the implementation of plants in the indoor environment of buildings to reduce the concentration of CO2. Based on a specified model representing the internal environment of an office space, it was studied whether the requirement for the total amount of ventilated air could be reduced by using plants, thereby achieving savings of operating costs in the building ventilation sector. The present research describes the effect of plant implementation according to different levels of CO2 concentration of the supply air, specifically with values of 410 ppm corresponding to the year 2020, 550 ppm to the year 2050 and 670 ppm to the year 2100, as well as according to different levels of CO2 concentration in the indoor environment, namely 1000 ppm and 1500 ppm, the illumination of plants in the indoor environment is constant in the model, PPFD equals to 200 μmolm−2 s−1. Based on the computational model, it was found that the implemented plants can positively influence the requirement for the total amount of ventilated air, the most significant effect is in the case of a low indoor environment quality, with the CO2 concentration of 1500 ppm, and a high supply air quality 410 p˙pm. The simulation also showed that compared to 2020, by the year 2100, it will be necessary to increase the ventilation of the indoor environment by 25.1% to ensure the same quality of the indoorenvironment.

利用植物降低建筑物中二氧化碳浓度的研究

本文论述了在建筑物的室内环境中种植植物以降低二氧化碳浓度。根据代表办公空间内部环境的特定模型，研究了是否可以通过使用植物来减少对通风总量的要求，从而节省建筑通风部门的运营成本。本研究描述了根据供应空气的不同CO2浓度水平，特别是对应于2020年的410ppm、对应于2050年的550ppm和对应于2100年的670ppm的值，以及根据室内环境中的不同CO2含量水平，即1000ppm和1500ppm，实施工厂的效果，模型中植物在室内环境中的光照是恒定的，PPFD等于200μmolm−2s−1。基于计算模型，研究发现，所实施的工厂可以对通风总量的要求产生积极影响，最显著的影响是在室内环境质量较低的情况下，CO2浓度为1500ppm，供应空气质量较高的情况下为410p*pm。模拟还显示，与2020年相比，到2100年，有必要将室内环境的通风量增加25.1%，以确保室内环境的质量不变。

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
