Lack of thermal comfort in the existing building stock in many warm summer climates and the COVID-19 pandemic have increased residents' temporary occupation of urban open spaces. However, climate change and other effects such as urban heat islands are also negatively affecting the livability of these spaces. Therefore, strategies are needed to improve the thermal conditions in these areas. In this context, the research designs, simulates and assesses an urban green infrastructure supported by an adaptative solar shading system. For this purpose, a public square to be renovated in Seville (Spain) is chosen. After an analysis of the current situation, more vegetation is added. However, trees are not planted fully grown, so their cover is not enough in the short term and an artificial system that protects from the sun by casting shade and that adapts to both their growth and the seasons is included. The urban space is characterized by on-site measurements, proposing four (initial, intermediates and final) scenarios using computational fluid dynamics simulations in an holistic microclimate modelling system. In turn, changes in thermal comfort are analyzed using the COMFA model. Results show that the air and surface temperature are decreased, reducing the number of hours in discomfort by 21% thanks to incorporating the green structure and by 30% due to the vegetation. It can be concluded that the use of these temporary urban prostheses enables urban spaces regenerated with vegetation to be enjoyed without waiting 20 or 30 years for the trees to mature, encouraging people to spend more time outdoors from the start of the intervention.

在许多温暖的夏季气候和 COVID-19 大流行中，现有建筑存量缺乏热舒适性，增加了居民对城市开放空间的临时占用。然而，气候变化和城市热岛效应等其他影响也对这些空间的宜居性产生了负面影响。因此，需要采取策略来改善这些地区的热条件。在此背景下，该研究设计、模拟和评估了由自适应遮阳系统支持的城市绿色基础设施。为此，我们选择了塞维利亚（西班牙）的一个公共广场进行翻新。在分析当前情况后，添加了更多的植被。然而，树木并没有完全种植，因此它们的覆盖在短期内是不够的，并且包括一个通过投射阴影来保护免受阳光照射并适应它们的生长和季节的人工系统。城市空间的特点是现场测量，在整体微气候建模系统中使用计算流体动力学模拟提出四种（初始、中间和最终）情景。反过来，使用 COMFA 模型分析热舒适度的变化。结果表明，空气和地表温度降低，由于采用绿色结构，不适时间减少了 21%，由于植被减少了 30%。可以得出结论，使用这些临时的城市假肢，可以享受植被再生的城市空间，而无需等待 20 或 30 年的树木成熟，
