在多层商业建筑中，应用于建筑立面的太阳幕遮阳系统为管理太阳能热增益、日光穿透和眩光影响提供了机会。这些阴影类型被誉为被动的本土系统，作为低能耗的设计策略经受住了时间的考验。尽管人们对在当代建筑中采用这些本土策略越来越感兴趣，但缺乏从视觉、热质量和数量两方面研究不同屏幕几何形状、穿孔百分比、形状、材质之间的关系，以及它们对周边空间室内环境质量的影响。虽然之前已经研究过屏幕遮阳系统对建筑物形状的影响，但很少有研究比较这些屏幕系统对不同炎热气候区热舒适性的影响。 此外，尚未全面研究其节能、冷负荷和多舒适性潜力，以揭示这些系统对建筑物及其居住者的综合影响。本文旨在评估两个不同炎热气候区三种遮阳结构的动态能量性能和室内热舒适性；巴基斯坦拉合尔气候炎热潮湿，卡塔尔多哈气候炎热干燥。本文报告了一种多方法研究设计，结合三种不同几何形状和穿孔率的遮光系统的现场评估。使用动态环境建模软件Integrated Environments Solutions Virtual Environment（IES-VE）Apache thermal engine对不同系统的实验性能进行了模拟。 对两个代表性城市的ASHRAE典型年份气象数据进行了模拟。对既有办公楼朝南和朝西的玻璃幕墙的屏幕几何形状、深度和穿孔百分比等自变量进行了操纵。评估的因变量包括能源性能的降低、太阳能热增益系数、照明能量和室内热舒适性的改善。我们的现场研究和计算环境建模结果表明，在卡塔尔多哈气候区，深度为3-5厘米、穿孔率为30%、穿孔宽深比为1:1的筛网可以改善办公楼的热舒适性，并比更大的穿孔筛网提高能源性能。然而，穿孔率为50%的筛网更适合巴基斯坦拉合尔气候区。 然而，通过改变穿孔率，热舒适性更好，尤其是在巴基斯坦拉合尔等湿热气候条件下。屏幕几何结构的不同程度排列表明，太阳能屏幕的空隙和模式在炎热气候区的表现不同，由于中东地区城市内部和城市之间的各种微气候，从湿热、炎热干旱、炎热中等到炎热干燥，因此不应将结果推广到整个中东地区。这项研究表明，事实上，一种形式的太阳能屏并不适合所有炎热气候下的所有建筑。引文:2018年冬季会议，伊利诺伊州芝加哥，会议论文

Solar-Screen shading systems applied to building facades present an opportunity to manage solar heat gains, daylight penetration, and glare impacts in multi-story commercial buildings. These shading typologies are praised as passive vernacular systems that stood the test of time as low energy design strategies. Despite the increased interest in adopting these vernacular strategies in contemporary buildings, there is a lack of studies investigating the relationship between different screen geometries, perforation percentage, form, materiality, and their impacts on indoor environmental quality of the perimeter spaces from both the visual as well as the thermal qualities and quantities. While the impacts of screen shading systems on the building’s shape have been previously studied, few studies compared the impacts of these screen systems on thermal comfort in different hot climate zones. In addition, their energy savings, cooling loads, and multi-comfort potential have not been studied comprehensively to unveil the combined impacts of these systems on the building and its occupants. This paper aims to assess dynamic energy performance and indoor thermal comfort of three screen shading geometries in two different hot climate zones; Lahore, Pakistan, a hot-humid climate and Doha, Qatar, a hot-arid climate.The paper reports on a multi-method approach research design combining a field assessment of three screen-shading systems with different geometries and perforation percentages. Experimental performance of the different systems were simulated using a dynamic environmental modelling software, Integrated Environments Solutions-Virtual Environment (IES-VE) Apache thermal engine. The simulation was performed for an ASHRAE typical year meteorological weather data for the two representative city locations. Independent variables including screen geometry, depth, and perforation percentages were manipulated for both south and west-facing glazed façades of an existing office building. The dependent variables assessed were reductions in energy performance, solar heat gain coefficient, lighting energy, and improved indoor thermal comfort. Results from our field studies and computational environmental modelling revealed that screens with 3-5 cms in depth and 30% perforation ratio with 1:1 perforation width to depth ratio improve thermal comfort in office buildings and energy performance over larger perforated screens for Doha, Qatar climate zone.Screens with 50% perforation ratio, however, were better suited for Lahore, Pakistan climate zone. Thermal comfort, however, was better achieved with variable perforation ratios, especially for hot-humid climates such as, Lahore, Pakistan. Various degrees of permutations of screen geometries revealed that solar screens voids and patterns perform differently in hot climate zones and results should not be generalized across the Middle East region due to various micro-climates within and between cities of the region ranging from hot-humid, hot-arid, hot-moderate, to hot-dry. This study suggests that, indeed, solar screens of one form do not fit all buildings at all hot climates.
