Analysis of Cooling Mechanisms to Combat Heat Stress in the Construction Industry

---

Abstract

The purpose of this research was to determine the efficacy of various cooling technology garments based on a representative construction worker's ensemble, replicating a typical workday. An ANDI dynamic sweating thermal manikin was used to predict physiological responses (ManikinPC) under constant ambient conditions simulating a hot/humid outdoor working environment. Four commercially available cooling technology t-shirts and two active cooling vests were assessed. Each garment was compared to the control, a standard construction uniform with a 100% cotton t-shirt. A MET rate of 4.3 was selected for masonry construction for the 1-hour test duration. Three test replicates were performed for each cooling technology ensemble. Wearing VEST2 resulted in the lowest skin temperature, sweat rates, and most favorable comfort perceptions. Findings indicate the fiber content worn next to the skin plays a significant role in cooling pack effectiveness. Cooling vests were found to be more effective than cooling t-shirts.
