To effectively mitigate heat risks, it is crucial to pinpoint areas of high vulnerability and assess the severity of heat-related threats to construction workers. This paper advances the understanding of heat risks in construction by mapping the associated risks across time and space to support informed decision-making. This paper presents a framework for heat risk monitoring, enabled by a construction site digital twin. This framework leverages geometric modeling, incorporates real-time weather data from a weather station, and utilizes computational simulations for assessing spatio-temporal heat risks. Its effectiveness was validated through a case study in Stephenville, Texas, USA, where it demonstrated superior fidelity when compared to using the conventional black-globe thermometer. Moreover, the results substantiated that incorporating the spatio-temporal variability of heat risks enhances heat risk surveillance in construction workplaces. This approach offers practical insights into imminent heat-related threats, aiming to prevent potential heat-related accidents in construction.

建筑中的时空热风险分析：基于数字孪生的监控


为了有效降低高温风险，确定高度脆弱的区域并评估与高温相关的威胁对建筑工人的严重性至关重要。本文通过绘制跨时间和空间的相关风险来支持明智的决策，从而促进对建筑中热风险的理解。本白皮书提出了一个由建筑工地数字孪生实现的热风险监控框架。该框架利用几何建模，整合来自气象站的实时天气数据，并利用计算模拟来评估时空高温风险。它的有效性通过美国德克萨斯州斯蒂芬维尔的案例研究得到验证，与使用传统的黑球温度计相比，它表现出卓越的保真度。此外，结果证实，纳入热风险的时空变化可以增强建筑工作场所的热风险监测。这种方法为迫在眉睫的高温相关威胁提供了实用见解，旨在防止建筑中潜在的高温相关事故。
