Abstract

Previous studies have shown that vertical greening has a significant cooling and energy-saving effect, most of which are applied to opaque walls. However, windows are the critical factor contributing to the indoor thermal environment. This study developed a modular vertical greening shading device (MVGSD), and introduces its detailed structure: water supply mode, plant selection, and substrate preparation. To investigate the thermal performance of MVGSD, a structural model test was carried out. The results show that MVGSD has a noticeable effect on indoor temperature. Specifically, the greatest indoor temperature can be reduced by 4 °C and effectively low the concentration of CO (The CO absorption rate is 53.1%). In addition, the characteristics of the louver shading and MVGSD were compared, and it was found that the indoor temperature by using MVGSD is 2.6 °C lower than the louver. It is also worth mentioning that indoor humidity is improved by MVGSD, which has a beneficial effect on the thermal comfort of human beings.

摘要

先前的研究表明，垂直绿化具有显著的降温节能效果，其中大部分应用于不透明墙壁。然而，窗户是影响室内热环境的关键因素。本研究开发了一种模块化垂直绿化遮阳装置（MVGSD），并介绍了其详细的结构：供水模式、植物选择和基质准备。为了研究 MVGSD 的热性能，进行了结构模型测试。结果表明，MVGSD 对室内温度有显著影响。具体来说，最大室内温度可降低 4°C，并有效降低 CO 浓度（CO 吸收率为 53.1%）。此外，比较了百叶窗遮阳和 MVGSD 的特点，发现使用 MVGSD 的室内温度比百叶窗低 2.6°C。值得一提的是，MVGSD 提高了室内湿度，对人体热舒适有有益影响。
