State-of-the-art cooling technologies have predominantly focused on clothing (e.g. moisture wicking, phase change materials, active cooling technologies) for individuals who are performing high levels of physical activity. Additionally, materials currently used for clothing fabrics (e.g. cotton and polyester) have a transmittance of 1-2% in the infrared (IR) spectrum, which doesn't allow cooling via radiation. ITVOF are transparent in the infrared spectrum and increase a person’s cooling rate by >23W. Personal cooling rate and ambient temperature affect personal thermal comfort. Therefore, increasing a person's cooling rate allows a higher ambient temperature to achieve the same level of comfort. Specifically, a >23W increase in cooling rate allows an ambient temperature increase ≥ 4oF (to ~79oF), which leads to lower air conditiong set points and significant energy savings in buildings.
