An experimental data set for the analysis of the thermophysical behavior of a single-story naturally ventilated double-skin façade (DSF) under summer boundary conditions

Double-skin facades (DSFs) are adaptive building envelope elements that offer the possibility to dynamically interact with the heat and mass flow between indoor and outdoor environments. Though designed to provide better performance compared to more conventional envelope solutions, these façade systems may, in some cases, underperform and lead to an increase in energy use or in thermal discomfort if not properly designed and operated. One of the known problems is the risk of overheating, in hot periods, in the ventilated cavity. In order to analyze this effect, we have systematically investigated the performance of a single-story, naturally ventilated DSF. The DSF is operated in the so-called outdoor air curtain mode and has venetian blinds installed in the 20 mm deep ventilated cavity. Tests were carried out under a steady-state regime corresponding to relevant summertime conditions. In an effort to enable the scientific community to access experimental data to analyze this problem further or for model validation purposes, we released together with the open-access paper entitled "Characterization of a naturally ventilated double-skin façade through the design of experiments (DOE) methodology in a controlled environment," the entire set of experimental data collected during the tests. The data set contains the results of a series of experimental runs where different configurations of the DSF, as detailed below, have been subjected to various boundary conditions through a climate simulator facility equipped with a solar simulator device. The database is supported by a guide ("Guide.pdf"), where further explanations about how to read data and schematic drawings of the sensor layout are provided. Additional information about the original aims of the experiments, the detailed methods, and other data processing procedures can be found in the article mentioned above. The collection of experimental tests in this data set covers:

49 steady-state measurements where the following factors were changed using different experimental designs: solar irradiance (0, 350, and 700 Wm-2), outdoor chamber temperature (15, 25, and 35 ℃), opening size (7, 21, and 42 dm2), and venetian blinds angle (closed blinds θ=0 º, θ=45 º, and open blinds θ=90 º) [file name: "Complete_data.csv"],

双层表皮幕墙（Double-skin Facades, DSFs）是一种自适应建筑围护结构构件，可实现室内外环境间热量与质流的动态交互。尽管相较于传统围护结构方案，该类幕墙系统的设计初衷是实现更优性能，但如果设计与运维不当，在部分场景下其性能可能不佳，进而导致能源消耗增加或热舒适度下降。已知的问题之一是，在炎热时段，其通风空腔存在过热风险。

为分析该效应，本研究系统调研了单层自然通风双层表皮幕墙的性能表现。该双层表皮幕墙采用所谓的室外空气幕模式运行，在深度20 mm的通风空腔内安装了百叶帘。测试在符合典型夏季工况的稳态条件下开展。

为便于科研人员获取实验数据以开展该问题的进一步研究或用于模型验证，我们随开放获取论文《基于控制环境下的实验设计（Design of Experiments, DOE）方法表征自然通风双层表皮幕墙》发布了测试期间采集的全部实验数据集。本数据集包含一系列实验测试的结果：通过配备太阳模拟器的气候模拟装置，为不同配置的双层表皮幕墙施加各类边界条件，具体配置详述如下。

该数据集附带一份指南文件（"Guide.pdf"），其中包含数据读取方法的详细说明以及传感器布局的示意图。关于实验初始目标、详细研究方法及其他数据处理流程的更多信息，可参见上述论文。

本数据集收录的实验测试包括：
49组稳态测试，通过不同实验设计改变以下参数：太阳辐照度（0、350、700 W·m⁻²）、室外腔室温度（15、25、35 ℃）、开口面积（7、21、42 dm²）以及百叶帘角度（闭合θ=0°、θ=45°以及开启θ=90°）[文件名："Complete_data.csv"]。
