The project described was supported by the Research Experience for Undergraduates Program Site: Materials for Society at Boise State University under Award No. 1658076.
Abstract
Many studies have been conducted to find possible strategies for reducing the Urban Heat Island (UHI) effect during hot summer months. One of the largest contributors to UHI is the role paved surfaces play in the warming of urban areas. The use of heat-reflective coatings to combat the effects of pavement have been previously studied, with mixed conclusions. While studies show that heat-reflective coatings may have many useful applications, this study is focused on their ability to reduce UHI. To elaborate this, a concrete sample is put through tests in which it is heated with a halogen lamp and the surface temperature is measured using an infrared thermal camera. The air temperature and body temperatures at varying depths are also recorded using a thermometer and thermocouple respectively. Analyzing the limited results that have been collected thus far found that the concrete was cooler when coated as compared to the concrete samples without coating. This conclusion shows that heat-reflective coatings are capable of reducing the surface temperature of concrete and may have the potential to lessen UHI effects in cities.
